Introduction
The National Center for Health Statistics (NCHS) of the Centers for Disease
Control and Prevention (CDC) collects, analyzes, and disseminates data on
the health status of U.S. residents. The results of surveys, analyses, and
studies are made known through a number of data release mechanisms
including publications, mainframe computer data files, CD-ROMs (Search and
Retrieval Software, Statistical Export and Tabulation System (SETS)), and the
Internet (http://www.cdc.gov/nchswww/nchshome.htm).
The National Health and Nutrition Examination Survey (NHANES) is a periodic
survey conducted by NCHS. The third National Health and Nutrition
Examination Survey (NHANES III), conducted from 1988 through 1994, was the
seventh in a series of these surveys based on a complex, multi-stage sample
plan. It was designed to provide national estimates of the health and
nutritional status of the United States' civilian, noninstitutionalized
population aged two months and older.
Data from NHANES III are being released in five public release data files:
NHANES III Household Adult Data File (Catalog Number 77560)
NHANES III Household Youth Data File (Catalog Number 77550)
NHANES III Examination Data File (Catalog Number 76200)
NHANES III Laboratory Data File (Catalog Number 76300)
NHANES III Dietary Recall Data Files (Catalog Number 76700)

GUIDELINES FOR DATA USERS
Please refer to the following important information before analyzing data.
NHANES III Background Documents
o The Plan and Operation of the Third National Health and Nutrition
Examination Survey, 1988-94, (NCHS, 1994; U.S. DHHS, 1996) provides an
overview of the survey and includes copies of the survey forms.
o The sample design, nonresponse, and analytic guidelines documents on
the NHANES III Reference Manuals and Reports CD-ROM (U.S. DHHS, 1996)
discuss the reasons that sample weights and the complex survey design
should be taken into account when conducting any analysis.
o Instruction manuals, laboratory procedures, and other NHANES III
reference manuals on the NHANES III Reference Manuals and Reports
CD-ROM(U.S. DHHS, 1996) are also available for further information on
the details of the survey.
Analytic Data Set Preparation
o Most NHANES III survey design and demographic variables are found only
on the Adult and Youth Household Data Files. In preparing a data set
for analysis, other data files must be merged with either or both of
these files to obtain many important analytic variables.
o All of the NHANES III public use data files are linked with the common
survey participant identification number (SEQN). Merging information
from multiple NHANES III data files using this variable ensures that
the appropriate information for each survey participant is linked
correctly.
o NHANES III public use data files do not have the same number of
records on each file. The Household Questionnaire Files (divided into
two files, Adult and Youth) contain more records than the Examination
Data File because not everyone who was interviewed completed the
examination. The Laboratory Data File contains data only for persons
aged one year and older. The Individual Foods Data File based on the
dietary recall has multiple records for each person rather than the one
record per sample person contained in the other data files.
o For each data file, SAS program code with standard variable names and
labels is provided as separate text files on the CD-ROM that contains
the data files. This SAS program code can be used to create a SAS
data set from the data file.
o Modifications were made to items in the questionnaires, laboratory,
and examination components over the course of the survey; as a result,
data may not be available for certain variables for the full six years.
In addition, variables may differ by phase since some changes were
implemented between phases. Users are encouraged to read the Notes
sections of this document carefully for information about changes.
o Extremely high and low values have been verified whenever possible,
and numerous consistency checks have been performed. Nonetheless, users
should examine the range and frequency of values before analyzing
data.
o Some data were not ready for release at the time of this publication
due to continued processing of the data or analysis of laboratory
specimens. A listing of those data are available in the general
information section of each data file.
o Confidential and administrative data are not being released to the
public. Additionally, some variables have been recoded to help
protect the confidentiality of the survey participants. For example,
all age-related variables were recoded to 90+ years for persons who were
90 years of age and older.
o Some variable names may differ from those used in the Phase 1 NHANES
III Provisional Data Release and some variables included in the Phase 1
provisional release may not appear on these files.
o Although the data files have been edited carefully, errors may be
detected. Please notify NCHS staff (301-436-8500) of any errors in
the data file or the documentation.
Analytic Considerations
o NHANES III (1988-94) was designed so that the survey's first three
years, 1988-91, its last three years, 1991-94, and the entire six
years were national probability samples. Analysts are encouraged to use
all six years of survey results.
o Sample weights are available for analyzing NHANES III data. One of
the following three sample weights will be appropriate for nearly all
analyses: interviewed sample final weight (WTPFQX6), examined sample
final weight (WTPFEX6), and mobile examination center (MEC)- and
home-examined sample final weight (WTPFHX6). Choosing which of these
sample weights to use in any analysis depends on the variables being
used. A good rule of thumb is to use "the least common denominator"
approach. In this approach, the user checks the variables of
interest. The variable that was collected on the smallest number of
persons is the "least common denominator," and the sample weight that
applies to that variable is the appropriate one to use for that
analysis. For more detailed information, see the Analytic and Reporting
Guidelines for NHANES III (U.S. DHHS, 1996).

SURVEY DESCRIPTION
The third National Health and Nutrition Examination Survey (NHANES III) was
the seventh in a series of large health examination surveys conducted in
the United States beginning in 1960. Three of these surveys, the National
Health Examination Surveys (NHES), were conducted in the 1960's (NCHS, 1965;
NCHS, 1967; NCHS, 1969). In 1970, an expanded nutrition component was added
to provide data with which to assess nutritional status and dietary
practices, and the name was changed to the National Health and Nutrition
Examination Survey (Miller, 1973; Engel, 1978; McDowell, 1981). A special
survey of Hispanic populations in the United States was conducted during
1982-1984 (NCHS, 1985).
The general structure of the NHANES III sample design was similar to that
of the previous NHANES. All of the surveys used complex, multi-stage,
stratified, clustered samples of civilian, noninstitutionalized
populations. NHANES III was the first NHANES without an upper age limit; in
fact, the age range for the survey was two months and older. A home
examination option was employed for the first time in order to obtain
examination data for very young children and for elderly persons who were
unable to visit the mobile examination center (MEC). The home examination
included only a subset of the components used in the full MEC examination
since it would have been difficult to collect some types of data in a home
setting. A detailed description of design specifications and copies of the
data collection forms can be found in the Plan and Operation of the Third
National Health and Nutrition Examination Survey, 1988-1994 (NCHS, 1994; U.S.
DHHS, 1996).
NHANES III was conducted from October 1988 through October 1994 in two
phases, each of which comprised a national probability sample. The first
phase was conducted from October 18, 1988, through October 24, 1991, at 44
locations. The second phase was conducted from September 20, 1991, through
October 15, 1994, at 45 different locations. In NHANES III, 39,695 persons
were selected over the six years; of those, 33,994 (86%) were interviewed
in their homes. All interviewed persons were invited to the MEC for a
medical examination. Seventy-eight percent (30,818) of the selected persons
were examined in the MEC, and an additional 493 persons were given a special,
limited examination in their homes.
Data collection began with a household interview. Several questionnaires
were administered in the household: Household Screener Questionnaire,
Family Questionnaire, Household Adult Questionnaire, and Household Youth
Questionnaire.
At the MEC, an examination was performed, and five automated questionnaires
or interviews were administered: MEC Adult Questionnaire, MEC Youth
Questionnaire, MEC Proxy Questionnaire, 24-Hour Dietary Recall, and Dietary
Food Frequency (ages 12-16 years). The health examination component
included a variety of tests and procedures. The examinee's age at the time
of the interview and other factors determined which procedures were
administered. Blood and urine specimens were obtained, and a number of tests
and measurements were performed including body measurements, spirometry,
fundus photography, x-rays, electrocardiography, allergy and glucose
tolerance tests, and ultrasonography. Measurements were taken of bone
density, hearing, and physical, cognitive, and central nervous system
functions. A physician performed a limited standardized medical examination
and a dentist performed a standardized dental examination. While some of the
blood and urine analyses were performed in the MEC laboratory, most analyses
were conducted elsewhere by contract laboratories.
A home examination was conducted for those sample persons aged 2-11 months
and aged 20 years or older who were unable to visit the mobile examination
center. The home examination consisted of an abbreviated version of the
tests and interviews performed in the MEC. Depending on age of the sample
person, the components included body measurements, blood pressure,
spirometry, venipuncture, physical function evaluation, and a questionnaire
to inquire about infant feeding, selected health conditions, cognitive
function, tobacco use, and reproductive history.
SAMPLE DESIGN AND ANALYSIS GUIDELINES
Sample Design
The general structure of the NHANES III sample design is the same as that
of the previous NHANES. Each of these surveys used a stratified, multi-stage
probability design. The major design parameters of the two previous NHANES
and the special Hispanic HANES, as well as NHANES III, have been previously
summarized (Miller, 1973; McDowell, 1981; NCHS, 1985; NCHS, 1994). The
NHANES III sample was designed to be self-weighting within a primary
sampling unit (PSU) for subdomains (age, sex, and race-ethnic groups). While
the sample was fairly close to self-weighting nationally for each of these
subdomain groups, it was not representative of the total population, which
includes institutionalized, non-civilian persons that were outside the
scope of the survey.
The NHANES III sample represented the total civilian, noninstitutionalized
population, two months of age or over, in the 50 states and the District of
Columbia of the United States. The first stage of the design consisted of
selecting a sample of 81 PSU's that were mostly individual counties. In a
few cases, adjacent counties were combined to keep PSU's above a minimum
population size. The PSU's were stratified and selected with probability
proportional to size (PPS). Thirteen large counties (strata) were chosen
with certainty (probability of one). For operational reasons, these 13
certainty PSU's were divided into 21 survey locations. After the 13
certainty strata were designated, the remaining PSU's in the United States
were grouped into 34 strata, and two PSU's were selected per stratum (68
survey locations). The selection was done with PPS and without
replacement. The NHANES III sample therefore consists of 81 PSU's or 89
locations.
The 89 locations were randomly divided into two groups, one for each phase.
The first group consisted of 44 and the other of 45 locations. One set
of PSU's was allocated to the first three-year survey period (1988-91) and
the other set to the second three-year period (1991-94). Therefore,
unbiased estimates (from the point of view of sample selection) of health and
nutrition characteristics can be independently produced for both Phase 1
and Phase 2 as well as for both phases combined.
For most of the sample, the second stage of the design consisted of area
segments composed of city or suburban blocks, combinations of blocks, or
other area segments in places where block statistics were not produced in
the 1980 Census. In the first phase of NHANES III, the area segments were
used only for a sample of persons who lived in housing units built before
1980. For units built in 1980 and later, the second stage consisted of sets
of addresses selected from building permits issued in 1980 or later. These
are referred to as "new construction segments." In the second phase, 1990
Census data and maps were used to define the area segments. Because the
second phase followed within a few years of the 1990 Census, new construction
did not account for a significant part of the sample, and the entire sample
came from the area segments.
The third stage of sample selection consisted of households and certain
types of group quarters, such as dormitories. All households and eligible
group quarters in the sample segments were listed, and a subsample was
designated for screening to identify potential sample persons. The
subsampling rates enabled production of a national, approximately
equal-probability sample of households in most of the United States with
higher rates for the geographic strata with high Mexican-American
populations. Within each geographic stratum, there was a nearly
equal-probability sample of households across all 89 stands.
Persons within the sample of households or group quarters were the fourth
stage of sample selection. All eligible members within a household were
listed, and a subsample of individuals was selected based on sex, age, and
race or ethnicity. The definitions of the sex, age, race or ethnic
classes, subsampling rates, and designation of potential sample persons
within screened households were developed to provide approximately
self-weighting samples for each subdomain within geographic strata and at the
same time to maximize the average number of sample persons per sample
household. Previous NHANES indicated that this increased the overall
participation rate. Although the exact sample sizes were not known until
data collection was completed, estimates were made. Below is a summary of
the sample sizes for the full six-year NHANES III at each stage of selection:
Number of PSU's 81
Number of stands (survey locations) 89
Number of segments 2,144
Number of households screened 93,653
Number of households with sample persons 19,528
Number of designated sample persons 39,695
Number of interviewed sample persons 33,994
Number of MEC-examined sample persons 30,818
Number of home-examined sample persons 493
More detailed information on the sample design and weighting and estimation
procedures for NHANES III can be found in the Plan and Operation of the
Third National Health and Nutrition Examination Survey, 1988-94 (NCHS, 1994;
U.S. DHHS, 1996) and in the Analytic and Reporting Guidelines: Third National
Health and Nutrition Examination Survey (NHANES III), 1988-94 (U.S. DHHS,
1996).
Analysis Guidelines
Because of the complex survey design used in NHANES III, traditional
methods of statistical analysis based on the assumption of a simple random
sample are not applicable. Detailed descriptions of this issue and possible
analytic methods for analyzing NHANES data have been described earlier (NCHS,
1985; Yetley, 1987; Landis, 1982; Delgado, 1990). Recent analytic and
reporting guidelines that should be used for most NHANES III analyses and
publications are contained in Analytic and Reporting Guidelines (U.S. DHHS,
1996). These recommendations differ slightly from those used by analysts for
previous NHANES surveys. These suggested guidelines provide a framework to
users for producing estimates that conform to the analytic design of the
survey. All users are strongly urged to review these analytic and reporting
guidelines before beginning any analyses of NHANES III data.
It is important to remember that this set of statistical guidelines is not
absolute. When conducting analyses, the analyst needs to use his/her
subject matter knowledge (including methodological issues) as well as
information about the survey design. The more one deviates from the original
analytic categories defined in the sample design, the more important it is to
evaluate the results carefully and to interpret the findings cautiously.
In NHANES III, 89 survey locations were randomly divided into two sets or
phases, the first consisting of 44 and the other of 45 locations. One set
of PSU's was allocated to the first three-year survey period (1988-91) and
the other set to the second three-year period (1991-94). Therefore, unbiased
national estimates of health and nutrition characteristics can be
independently produced for each phase as well as for both phases combined.
Computation of national estimates from both phases combined (i.e., total
NHANES III) is the preferred option; individual phase estimates may be
highly variable. In addition, individual phase estimates are not
statistically independent. It is also difficult to evaluate whether
differences in individual phase estimates are real or due to methodological
differences. That is, differences may be due to changes in sampling methods
or data collection methodology over time. At this time, there is no valid
statistical test for examining differences between Phase 1 and Phase 2.
Therefore, although point estimates can be produced separately for each
phase, no test is available to test whether those estimates are
significantly different from each other.
NHANES III is based on a complex, multi-stage probability sample design.
Several aspects of the NHANES design must be taken into account in data
analysis, including the sample weights and the complex survey design.
Appropriate sample weights are needed to estimate prevalence, means,
medians, and other statistics. Sample weights are used to produce correct
population estimates because each sample person does not have the same
probability of selection. The sample weights incorporate the differential
probabilities of selection and include adjustments for noncoverage and
nonresponse. A detailed discussion of nonresponse adjustments and issues
related to survey coverage have been published (U.S. DHHS, 1996). With the
large oversampling of young children, older persons, black persons, and
Mexican-Americans in NHANES III, it is essential that the sample weights be
used in all analyses. Otherwise, a misinterpretation of results is highly
likely. Other aspects of the design that must be taken into account in data
analyses are the strata and PSU pairings from the sample design. These
pairings should be used to estimate variances and test for statistical
significance. For weighted analyses, analysts can use special computer
software packages that use an appropriate method for estimating variances for
complex samples such as SUDAAN (Shah, 1995) and WesVarPC (Westat, 1996).
Although initial exploratory analyses may be performed on unweighted data
using standard statistical packages and assuming simple random sampling,
final analyses should be done on weighted data using appropriate sample
weights. A summary of the weighting methodology and the type of sample
weights developed for NHANES III is included in Weighting and Estimation
Methodology (U.S. DHHS, 1996).
The purpose of weighting the sample data is to permit analysts to produce
estimates of statistics that would have been obtained if the entire
sampling frame (the United States) had been surveyed. Sample weights can be
considered as measures of the number of persons the particular sample
observation represents. Weighting takes into account several features of
the survey: the specific probabilities of selection for the individual
domains that were oversampled as well as nonresponse and differences between
the sample and the total U.S. population. Differences between the sample and
the population may arise due to sampling variability, differential
undercoverage in the survey among demographic groups, and possibly other
types of response errors, such as differential response rates or
misclassification errors. Sample weighting in NHANES III was used to:
1. Compensate for differential probabilities of selection among subgroups
(i.e., age-sex-race-ethnicity subdomains where persons living in
different geographic strata were sampled at different rates);
2. Reduce biases arising from the fact that nonrespondents may be
different from those who participate;
3. Bring sample data up to the dimensions of the target population
totals;
4. Compensate, to the extent possible, for inadequacies in the sampling
frame (resulting from omissions of some housing units in the listing
of area segments, omissions of persons with no fixed address, etc.); and
5. To reduce variances in the estimation procedure by using auxiliary
information that is known with a high degree of accuracy.
In NHANES III, the sample weighting was carried out in three stages. The
first stage involved the computation of weights to compensate for unequal
probabilities of selection (objective 1, above). The second stage adjusted
for nonresponse (objective 2). The third stage used poststratification of
the sample weights to Census Bureau estimates of the U.S. population to
accomplish the third, fourth, and fifth objectives simultaneously. In
NHANES III, several types of sample weights (see the sample weights table
that follows) were computed for the interviewed and examined sample and are
included in the NHANES III data file. Also, sample weights were computed
separately for Phase 1 (1988-91), Phase 2 (1991-94), and total NHANES III
(1988-94) to facilitate analysis of items collected only in Phase 1, only
in Phase 2, and over six years of the survey. Three sets of pseudo strata
and PSU pairings are provided to use with SUDAAN in variance estimation.
Since NHANES III is based on a complex, multi-stage sample design,
appropriate sample weights should be used in analyses to produce national
estimates of prevalence and associated variances while accounting for
unequal probability of selection of sample persons. For example, the final
interview weight, WTPFQX6, should be used for analysis of the items or
questions from the family or household questionnaires, and the final MEC
examination weight, WTPFEX6, should be used for analysis of the
questionnaires and measurements administered in the MEC. Furthermore, for a
combined analysis of measurements from the MEC examinations and associated
medical history questions from the household interview, the final MEC
examination weight, WTPFEX6, should be used. We recommend using SUDAAN
(Shah, 1995) to estimate statistics of interest and the associated variance.
However, one can also use other published methods for variance estimation.
Application of SUDAAN and alternative methods, such as the average design
effect approach, balance repeated replication (BRR) methods, or jackknife
methods for variance estimation, are discussed in Weighting and Estimation
Methodology (U.S. DHHS, 1996).
Appropriate Uses of the NHANES III Sample Weights

Use only in conjunction with the MEC- and home-examined persons
assigned to the afternoon/evening subsample and with items
collected during the MEC and home examinations.
DATA PREPARATION AND PROCESSING PROCEDURES
Automated data collection procedures for the survey were introduced in
NHANES III. In the mobile examination centers, data for the interview and
examination components were recorded directly onto a computerized data
collection form. With the exception of a few independently automated
systems, the system was centrally integrated. This operation allowed for
ongoing monitoring of much of the data. Before the introduction of the
computer-assisted personal interview (CAPI), the household questionnaire
data were reviewed manually by field editors and interviewers. CAPI
(1992-1994 only) questionnaires featured built-in edits to prevent entering
inconsistencies and out-of-range responses. The multi-level data
collection and quality control systems are discussed in detail in the Plan
and Operation of the Third National Health and Nutrition Examination Survey,
1988-1994 (NCHS, 1994; U.S. DHHS, 1996). All interview, laboratory, and
examination data were sent to NCHS for final processing.
Guidelines were developed that provided standards for naming variables,
filling missing values and coding conventional responses, handling missing
records, and standardizing two-part quantity/unit questionnaire variables.
NCHS staff, assisted by contract staff, developed data editing
specifications that checked data sets for valid codes, ranges, and skip
pattern consistencies and examined the consistency of values between
interrelated variables. Comments, collected in both interviews and
examination components, were reviewed and recoded when possible. Responses
to "Other" and "Specify" were recoded either to existing code categories or
to new categories. The documentation for each data set includes notes for
those variables that have been recoded and standardized and for those
variables that differ significantly from what appears in the original data
collection instrument. While the data have undergone many quality control
and editing procedures, there still may be values that appear extreme or
illogical. Values that varied considerably from what was expected were
examined by analysts who checked for comments or other responses that might
help to clarify unusual values. Generally, values were retained unless they
could not possibly be true, in which case they were changed to "Blank but
applicable." Therefore, the user must review each data set for extreme or
inconsistent values and determine the status of each value for analysis.
Several editing conventions were used in the creation of final analytic
data sets:
1. Standardized variables were created to replace all two-part
quantity/unit questions using standard conversion factors.
Standardized variables have the same name as the variable of the
two-part question with an "S" suffix. For instance, MAPF18S (Months
received WIC benefits) in the MEC Adult Questionnaire was created from
the two-part response option to question F18, "How long did you receive
benefits from the WIC program?," using the conversion factor 12 months
per year.
2. Recoded variables were created by combining responses from two or more
like variables, or by collapsing responses to create a summary
variable for the purpose of confidentiality. Recoded variables have the
original variable name with an R suffix. For example, place of birth
variable (HFA6X) in the Family Questionnaire was collapsed to a three
level response category (U.S., Mexico, Other) and renamed HFA6XCR.
Generally, only the recoded variable has been included in the data file.
3. Fill values, a series of one or more digits, were used to represent
certain specific conditions or responses. Below is a list of the fill
values that were employed. Some of the fill values pertain only to
questionnaire data, although 8-fill and blank-fill values are found in
all data sets. Other fill values, not included in this list, are used
to represent component-specific conditions.
6-fills = Varies/varied. (Questionnaires only)
7-fills = Fewer than the smallest number that could be reported within
the question structure (e.g., fewer than one cigarette per day).
(Questionnaires only)
8-fills = Blank but applicable/cannot be determined. This means that
a respondent was eligible to receive the question, test, or component
but did not because of refusal, lack of time, lack of staff, loss of
data, broken vial, language barrier, unreliability, or other similar
reasons.
9-fills = Don't know. This fill was used only when a respondent did
not know the response to a question and said, "I don't know."
(Questionnaires only)
Blank fills = Inapplicable. If a respondent was not eligible for a
questionnaire, test, or component because of age, gender, or specific
reason, the variable was blank-filled. In the questionnaire, if a
respondent was not asked a question because of a skip-pattern,
variables corresponding to the question were blank-filled. For
examination or laboratory components, if a person was excluded by a
defined protocol (e.g., screening exclusion questions) and these
criteria are included in the data set, then the corresponding
variables were blank-filled for that person. For home examinees,
variables for examination components and blood tests not performed as
part of the home examination protocol were blank-filled.
4. For variables describing discrete data, codes of zero (0) were used to
mean "none," "never," or the equivalent. Value labels for which "0"
is used include: "has not had," "never regularly," "still taking," or
"never stopped using." Unless otherwise labeled, for variables
containing continuous data, "zero" means "zero.
5. Where there are logical skip patterns in the flow of the questionnaire
or examination component, the skip was indicated by placing the
variable label of the skip destination in parentheses as part of the
value label of the response generating the skip. For example, in the
Physical Function Evaluation, the variable PFPWC (in wheelchair) has a
value label, "2 No (PFPSCOOT)" that means that the next item for
persons not in a wheelchair would be represented by the variable,
PFPSCOOT.
Variable Nomenclature
A unique name was assigned to every NHANES III variable using a standard
convention. By following this naming convention, the origin of each
variable is clear, and there is no chance of overlaying similar variables
across multiple components. Variables range in length from three to eight
characters. The first two variable characters represent the topic (e.g.,
analyte, questionnaire instrument, examination component) and are listed
below alphabetically by topic. For questionnaires administered in the
household, the remainder of the variable name following the first two
characters indicates the question section and number. For example, data
for the response to the Household Adult Questionnaire question B1 are
contained in the variable HAB1. For most laboratory and examination
variables, as well as some other variables, a "P" in the third position
refers to "primary" and the remainder of the variable name is a brief
description of the item. For instance, in the Laboratory Data File,
information on the length of time the person fasted before the first blood
draw is contained in the variable PHPFAST. The variable PHPFAST was derived
as follows: characters 1-2 (PH) refer to "phlebotomy," character 3 (P)
refers to "primary," characters 4-8 (FAST) refer to an abbreviation for
"fasting."

NHANES III Household Youth Data File
GENERAL INFORMATION
The NHANES III Household Youth Questionnaire Data File contains all data
collected during the household interviews for children and youths 2 months to 16
years of age. Demographic data, survey design variables, and sampling weights
for this age group are also included. This first section provides a brief
background and information about the contents of the Household Youth
Questionnaire Data File. The second section is the Data File Index, a
listing of all of the variables with the standard names and their positions in
the data set. The third section contains the frequency counts and codes for
all of the variables, followed by notes and appendices. References are found
in the fourth section.
The data that comprise this file were obtained from three separate interviews
administered in the household: the Screener, the Family, and Household Youth
questionnaires. The Screener was a brief interview administered to all
households within selected sampling units to determine eligibility for
participation in the survey. Information obtained from the Screener
questionnaire was the basis for the demographic variables, and survey-related
variables. The purpose of the Family questionnaire was to obtain data on
educational levels, occupation, health insurance coverage, income, and food
security of family members, and to record characteristics of the house itself.
The Household Youth questionnaire was administered to a proxy respondent,
usually the child's parent or guardian. Questions on topics such as birth
experience, motor and social development, health services usage, dental care,
selected medical conditions, school attendance, language, and vitamin, mineral
and medicine usage were asked according to age subgroups. The Household
Youth questionnaire was completed for 13,944 children and youths ages 2 months -
16 years of age during the six years of NHANES III.
Interviews were conducted by field staff, in both English and Spanish. All
staff received intensive initial training, and formal retraining was conducted
throughout the survey to ensure that high skill levels were maintained. The
data collection system was automated in Phase 2, at which time interviews were
conducted using CAPI (computer-assisted personal interview). Details on survey
instruments and forms, training manuals and data collection procedures are
published elsewhere (U.S. DHHS, 1996).
Data processing and editing were performed for consistency of responses within
sections of the questionnaire sections. Identifiable information including
names, addresses, and social security numbers, as well as other administrative
items were excluded from the data file in order to ensure confidentiality. Notes
are provided both for standardized and recoded variables, and for variables
requiring additional explanation. Hand cards and other diagrams that were used
during interviews are located with copies of the survey instruments in the Plan
and Operation of the Third National Health and Nutrition Examination Survey
(U.S. DHHS, 1996). Users should note that because questions were modified,
reordered, added, or deleted, this documentation may not follow the
exact ordering of the questions on survey instruments.
Since NHANES III was based on a complex multistage design, appropriate sample
weights should be used in analyses to produce national estimates and associated
variances. The final interview weights WTPFQX6 should be used for analysis of
interview data alone. If interview data are combined with examination,
laboratory or dietary data, the total MEC weights (WTPFEX6) or MEC+home weights
(WTPFHX6) should be used.

NOTES
Demographic Data
DMPSTAT: Examination/interview status
This variable identifies the interview or examination status of all persons
selected for the NHANES III sample. Interviewed persons completed
preselected questions in specific sections of the Household Adult or Youth
Questionnaires. Mobile examination center (MEC)-examined persons were
interviewed and successfully completed at least one examination component
in the MEC. Home-examined persons were interviewed and successfully
completed at least one home examination component. The home examination
was an option for frail older adults, infants 2-11 months of age, and other
adults who were unable to come to the MEC.
DMARETHN: Race-ethnicity
This key analytic variable, based on the NHANES III survey design, was
derived from many sources of data and is based on reported race and
ethnicity. The other category includes all Hispanics, regardless of
race, who were not Mexican-American and also includes all non-Hispanics
from racial groups other than white or black.
DMARACER: Race
This variable was obtained from two primary sources: the Screener and
the Family Questionnaires. Prior to the selection of the sample, race
(Black, White, Other) was self-reported or reported by proxy in the
Screener Questionnaire. During the administration of the Family
Questionnaire, race was self-reported or reported by the respondent of
the Family Questionnaire from five categories (Aleut, Eskimo, American
Indian, Asian or Pacific Islander, Black, White, Other). Responses from
the two sources were adjudicated, as necessary, to create a three level
variable (Black, White, Other).
DMAETHNR: Ethnicity
This variable was obtained from two primary sources: the Screener and
the Family Questionnaires. As part of both interviews, hand cards were
used to determine Mexican/Mexican-American or Other Latin
American/Spanish ancestry or national origin. Responses of non-Hispanic
ancestry or national origin were categorized as other. Responses from
the two interviews were adjudicated, as necessary, and this three
level variable was created.
HSAGEIR: Age (Screener Questionnaire)
Age was calculated using the birth date which was obtained from the
Screener Questionnaire. The variable HSAGEU provides the age unit
(months or years) for HSAGEIR. Ages of 90 years or greater were recoded
into a single category of 90+ years to help protect the confidentiality
of survey participants.
HSAITMOR: Age in months (Screener Questionnaire)
Age in months was calculated by computing number of months between the
Screener Questionnaire date and date of birth. This variable was
created for analyses where exact age at the interview may be needed.
HSAITMOR differs slightly from the age in years (HSAGEIR), the variable
most often used for analyses. Ages of 1080 months and older (90 years
and older) were recoded into a single category of 1080+ months to
protect the confidentiality of survey participants.
HSFSIZER: Family Size
Family size represents the total number of related persons living in a
household (single dwelling unit). All household members were rostered
by family during the Screener interview. Household members who were
related to the family reference person (knowledgeable household member
17 years or older who owned or rented the dwelling unit) by blood or
marriage were considered part of the family. Adopted children, foster-
and god-children were also included, if they were living in the dwelling
unit. However, family members who were away at college, or living
independently were not included. Other household members who were
unrelated to the reference person were considered members of separate
families. Families with 10 members or more were recoded into a single
response category of 10+ persons to help protect confidentiality. See
note for Household Size (HSHSIZER).
HSHSIZER: Household Size
Household size represents the total number of persons living in a single
dwelling unit, both related and unrelated. All permanent household
members were rostered according to their family as part the Screener
interview. This was done in order to obtain a complete list of all
persons living or staying in the dwelling unit, and to distinguish
household and family members. Households with 10 members or more were
recoded into a single response category of 10+ persons to help protect
confidentiality. See note for Family Size (HFHSIZER).
DMPCNTYR: County FIPS codes for United States counties with populations of
500,000 and more
These county FIPS codes identify large counties with populations of
500,000 and more that were sampled in the survey. Counties with
population less than 500,000 are not included to prevent identification
of these locations. See Appendix 1 for listing of codes.
DMPFIPSR: State FIPS codes for United States counties with populations of
500,000 and more
These state FIPS codes identify counties with populations of 500,000+
that were sampled in the survey. Counties with population less than
500,000 are not included to prevent identification of these locations.
See Appendix 1 for listing of codes.
DMPMETRO: Urbanization classification based on USDA Rural-Urban
continuum codes
These classifications are based on the USDA Rural-Urban codes (Butler and
Beale, 1993) that describe metro and nonmetro counties by degree of
urbanization and nearness to metro areas. The USDA codes were recoded
into two categories to prevent identification of counties that were
sampled in the survey.
DMPCREGN: Census region
The United States was divided into four broad geographic regions as
defined by the Bureau of Census. Because all states were not included in
the selected sample, regional estimates may not be representative for a
given region.
DMPPIR: Poverty income ratio (or poverty index)
The poverty income ratio (PIR) was computed as a ratio of two
components. The numerator was the midpoint of the observed family
income category in the Family Questionnaire variable:HFF19R. The
denominator was the poverty threshold, the age of the family reference
person, and the calender year in which the family was interviewed.
Poverty threshold values (in dollars) are produced annually by the
Census Bureau (Series P-60). These threshold values are based on
calendar years and adjusted for changes caused by inflation between
calendar years. Reports for each of the calendar years in the survey
(1988-94) were used in the calculation of PIR. For the years 1991 and
1994, data from preliminary reports were used. The poverty income ratio
allows income data to be analyzed in a comparable manner across the six
years of the survey and with previous NHANES.
Persons who reported having had no income and were assigned a zero value
for PIR. A substantial proportion of persons refused to report their
income or income category during the Family Questionnaire. Due to the
income nonresponse the potential for bias in PIR may be high. Users are
cautioned to examine potential nonresponse bias for PIR and
other income variables.
Survey Design Data
SDPPHASE: Phase of NHANES III survey
For operational purposes, 81 primary sampling units were divided into 89
survey locations (or stands) and randomly allocated to two three-year
phases. Phase 1 data were collected from October 1988 through October
1991 and Phase 2 data were collected from October 1991 through October
1994.
SDPSTRA6, SDPSTRA1, SDPSTRA2, and SDPPSU6, SDPPSU1, SDPPSU2: Pseudo strata
codes and pseudo PSU pair codes
Because NHANES III was based upon a complex sample design, the
assumptions of many statistical tests and routinely available
statistical programs are not met. For this reason, when estimates of
the variances of statistics are computed, the technique of estimation
must be based upon complex sampling theory. In order to provide users
with the capability of estimating the complex sample variances, 49
pseudo strata and a pair of Primary Sampling Unit (PSU) codes per
stratum were designed.
A software package, "SUDAAN- Software for the Statistical Analysis of
Correlated Data" (Shah, 1995), was developed by the Research Triangle
Institute to analyze complex sample design data like NHANES. SUDAAN
uses strata and PSU codes to conduct analysis with two PSU per stratum
design. Therefore, definition of pseudo strata and PSU provided in this
data file should be used to compute complex sample variances in
analyses. Other software available for estimation of complex sample
variance may also be used. For further discussion of methods of
variance estimation in NHANES III, see additional information on this
subject in Weighting and Estimation Methodology (U.S. DHHS, 1996) and
NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996).
Sampling Weights
WTPFQX6, WTPFQX1, WTPFQX2: Total NHANES III and phase-specific final
interview weights
These sampling weights should be used only for items collected during
the household interviews. To compute final interview weights, final
basic weights were first adjusted for nonresponse to household
interview, then post-stratified to the unpublished Current Population
Survey 1990 (Phase 1) and 1993 (Phase 2) population control estimates of
the U.S. population adjusted for undercount. For details, see
Weighting and Estimation Methodology (U.S. DHHS, 1996) and NHANES III
Analytic and Reporting Guidelines (U.S. DHHS, 1996).
WTPFEX6, WTPFEX1, WTPFEX2: Total NHANES III and phase-specific final MEC
examination weights
These MEC sampling weights should be used for analysis of measurements
or interview items collected in the MEC. Persons who were not examined
in the MEC have a sampling weight of zero and should be excluded from
analyses. To compute final MEC examination weights, final interview
weights were first adjusted for nonresponse to MEC examinations, then
post-stratified to the unpublished Current Population Survey 1990
(Phase 1) and 1993 (Phase 2) population control estimates of the U.S.
population adjusted for undercount. For details, see Weighting and
Estimation Methodology(U.S. DHHS, 1996) and NHANES III Analytic and
Reporting Guidelines (U.S. DHHS, 1996).
WTPFHX6, WTPFHX1, WTPFHX2: Total NHANES III and phase-specific MEC+home
examination weights
These MEC+home sampling weights should be used for analysis of the
examination items where measurements or interview items were collected
in the MEC and home. Persons who were not examined in the MEC or home
have a sampling weight of zero and should be excluded from analyses. To
compute final MEC+home examination weights, final interview weights were
first adjusted for nonresponse to MEC and home examinations, then
post-stratified to unpublished Current Population Survey 1990 (Phase 1)
and 1993 (Phase 2) population control estimates of the U.S. population
adjusted for undercount. No separate sampling weights were computed for
home examinees. For details, see Weighting and Estimation Methodology
(U.S. DHHS, 1996) and NHANES III Analytic and Reporting Guidelines
(U.S. DHHS, 1996).
WTPFALG6, WTPFALG1, WTPFALG2: Total NHANES III and phase-specific allergy
examination subsample weights
These subsample weights are for analysis of allergy measurements.
Allergy skin reactivity tests were administered to all MEC-examined
persons aged 6-19 years and a random half-sample of the adults aged
20-59 years. Eligible MEC-examined persons who did not complete the
allergy tests have a sampling weight of zero and should be excluded from
the analyses. Final MEC examination weights were first adjusted for
selection of the half-sample among adults (20-59 years), and
post-stratified to the unpublished Current Population Survey 1990 (Phase
1) and 1993 (Phase 2) population control estimates of the U.S.
population adjusted for undercount in the final step. For details, see
Weighting and Estimation Methodology (U.S. DHHS, 1996) and NHANES III
Analytic and Reporting Guidelines (U.S. DHHS, 1996).
WTPFCNS6, WTPFCNS1, WTPFCNS2: Total NHANES III and phase-specific central
nervous system (CNS) examination subsample final weights
These subsample weights are for analysis of measurements from the
Central Nervous System (CNS) test. The CNS examination was administered
to a random half-sample of the adults aged 20-69 years. Eligible
MEC-examined persons who did not complete CNS testing have a sampling
weight of zero and should be excluded from the analyses. Final MEC
examination weights were first adjusted for selection of half sample
among adults (20-59 years), and post-stratified to unpublished Current
Population Survey 1990 (Phase 1) and 1993 (Phase 2) population control
estimates of the U.S. population adjusted for undercount in the final
step. For details, see Weighting and Estimation Methodology
(U.S. DHHS, 1996) and NHANES III Analytic and Reporting Guidelines
(U.S. DHHS, 1996).
WTPFSD6, WTPFSD1, WTPFSD2: Total NHANES III and phase-specific morning
session MEC examination subsample final weights
These subsample weights are for special analyses where fasting time may
be an important factor. They were computed for persons aged 12 years
and older who were scheduled and examined in the MEC morning session.
Sampled households in the survey were randomly assigned to one of two
groups -- morning session ("standard") or afternoon/evening session
("modified") assignments. All sample persons from a household received
the same session assignment and were requested to schedule examinations
for the assigned session. Fasting instructions varied by age and
session assignment (Plan and Operation of The Third National Health and
Nutrition Examination Survey, 1988-94 , U.S. DHHS, 1996). It should be
noted that actual fasting time may have differed from the instructed
fasting time and can be obtained from the variable PHPFAST in the NHANES
III Laboratory Data File. To compute these weights, final MEC examination
weights were first adjusted for the random half selection, then
adjusted for the non-response to assigned session, and finally,
post-stratified to the unpublished Current Population Survey 1990 and
1993 Population control estimates of the U.S. population adjusted for
undercount. Eligible MEC-examined persons who were assigned to the morning
session and examined in another session have a sampling weight of zero and
should be excluded in analyses. For details, see Weighting and Estimation
Methodology (U.S. DHHS, 1996) and NHANES III Analytic and Reporting
Guidelines (U.S. DHHS, 1996).
WTPFMD6, WTPFMD1, WTPFMD2: Total NHANES III and phase-specific
afternoon/evening session MEC examination subsample final weights
These subsample weights are for special analyses where fasting time
might be an important factor. They were computed for MEC examined
persons aged 12 years and older who were scheduled and examined in the
afternoon or evening sessions. Sampled households in the survey were
randomly assigned to one of two groups -- morning session ("standard")
or afternoon/evening session ("modified") assignments. All sample

for the random half selection, then adjusted for the nonresponse to
assigned session, and finally, post-stratified to the unpublished Current
Population Survey 1990 and 1993 population control estimates of the U.S.
population adjusted for undercount. Eligible MEC examined persons who were
assigned to the afternoon or evening sessions and examined in
another session have a sampling weight of zero and should be excluded in
analyses. For details, see Weighting and Estimation Methodology
(U.S.DHHS, 1996) and NHANES III Analytic and Reporting Guidelines

WTPFHSD6, WTPFHSD1, WTPFHSD2: Total NHANES III and phase-specific morning
session MEC+home examination subsample final poststratified
weights
These subsample weights are for special analyses where fasting time may
be an important factor. They were computed for MEC+home examined
persons aged 12 years and older who were scheduled and examined in the
morning session. Sampled households in the survey were randomly
assigned to one of two groups -- morning session ("standard") or
afternoon/evening session ("modified") assignments. All sample persons

Reporting Guidelines (U.S. DHHS, 1996).
WTPFHMD6, WTPFHMD1, WTPFHMD2: Total NHANES III and phase-specific afternoon/
evening MEC+home examination subsample final weights
These subsample weights are for special analyses where fasting time may
be an important factor. They were computed for MEC+home examined

(U.S. DHHS, 1996).
WTPQRP1--WTPQRP52: Fay's BRR Replicate interview sample
To allow for alternative methods to estimate variance, 52 replicate
weights were computed using repeated sampling method where WESVAR or
other software that use repeated samples, can be used for estimating
variance. Fay's method (see Fay, 1990; Judkins, 1990) was used to draw
half samples and adjust sampling weights in each of the random half
samples. Sampling weights in one half sample were multiplied by the
factor k=1.7 and in the other half sample by k=0.3 using the Fay's
method. After this adjustment, sampling weights were further adjusted
for non-response and post-stratified using the same procedure as the
final full sample interview weights. These weights should be used only
for estimating variance of items from the household adult and youth
interviews. For details, see Weighting and Estimation Methodology
(U.S. DHHS, 1996) and NHANES III Analytic and Reporting Guidelines
(U.S. DHHS, 1996).
WTPXRP1--WTPXRP52: Fay's BRR Replicate weights for MEC- examined sample
To allow for alternative methods to estimate variance, 52 replicate
weights were computed using repeated sampling method where WESVAR or
other BRR type software can be used to estimate variance. Fay's method
(see Fay, 1990; Judkins, 1990) was used to draw half samples and adjust
sampling weights in each of the random half samples. Sampling weights
in one half sample were multiplied by the factor k=1.7 and in the other
half sample by k=0.3 using Fay's method. After this adjustment, weights
were further adjusted for nonresponse and were post-stratified using the
same procedure as the full sample final weights. These weights should
be used only for estimating variance of outcome measurements or
interview items from the MEC Examination. For details, see additional
information on this subject in Weighting and Estimation Methodology
(U.S. DHHS, 1996) and NHANES III Analytic and Reporting Guidelines (U.S.
DHHS, 1996).
Household Youth Questionnaire
HYAITMO: Age in months (Household Youth Interview)
Age in months was calculated by computing number of months between
Household Youth Interview date and the date of birth. It was created for
special analyses where exact age at the interview may be needed. This
computed age may be different from the self-reported age in HSAGEIR and
HSAGEU, or HSAITMOR. For most analyses, age reported in HSAGEIR (and
HSAGEU) should be used.
MEC Examination
MXPLANG: Language of MEC examination
This variables designates the language of conduct for the MEC examination.
questionnaires were designed to be implemented in a bilingual
(English/Spanish) format so that respondents could to be interviewed in
their preferred language. When it was necessary to conduct an interview
in a another language, a translator assisted the interviewer in
administering the questionnaires. These interviews were coded as other.
MXPSESSR: Examination session for MEC examinees
This variable designates the period during the day that the examination
occurred. To increase response rates and allow flexibility, examinations
were scheduled in three sessions: morning, afternoon and evening. On
occasion, more than one session was attended in order to complete the full
examination. In such a situation, the session was coded as the one when
most of the examinations were completed.
MXPAXTMR: Age in months at MEC examination
Age in total months was created for special analyses where exact age at the
examination may be needed (e.g., computation of growth charts). It was
calculated by computing number of months between examination date and the
date of birth. Some examinees may have had a birthday between household
interview and examination so that this computed age at examination may
differ slightly from the age reported in HSAGEIR (and HSAGEU), or HSAITMOR.
For most analyses age reported in HSAGEIR (and HSAGEU) should be used.
Ages of 1080 months and older (90 years and older) were recoded into a
single category of 1080+ months to protect the confidentiality of survey
participants.
Home Examination
HXPAXTMR: Age in months at home examination
Age in total months was created for special analyses where exact age at the
examination may be needed (e.g., computation of growth charts). It was
calculated by computing number of months between examination date and the
date of birth. Some examinees may have had a birthday between household
interview and examination so that this computed age at examination may
differ slightly from the age reported in HSAGEIR (and HSAGEU), or HSAITMOR.
For most analyses age reported in HSAGEIR (and HSAGEU) should be used.
Ages of 1080 months and older (90 years and older) were recoded into a
single category of 1080+ months to protect the confidentiality of survey
participants.
HXPSESSR: Examination session for home examinees
This variable designates the period during the day that the examination
occurred. To increase response rates and allow flexibility, examinations
were scheduled in three sessions: morning, afternoon and evening. On
occasion, more than one session was attended in order to complete the full
examination. In such a situation, the session was coded as the one when
most of the examinations were completed.
Family Questionnaire Notes
HFVERS: Version of household family questionnaire
During the six years of the survey, portions of the Family Questionnaire
were modified several times resulting in four different versions.
Questions were dropped, revised, or added to meet divergent research needs.
Changes were made in the ordering of selected questions, in the reference
time period, and in the wording of questions. Versions 1
and 2 were implemented during Phase 1, and Versions 3 and 4 were
implemented during Phase 2. Versions 3 and 4 vary only by implementation
mode; Version 3 was conducted by pencil and paper and Version 4 was
conducted using the computer-assisted personal interview (CAPI). The
Family Questionnaire printed in the Plan and Operation of the Third
National Health and Nutrition Examination Survey (U.S. DHHS, 1996) most
closely resembles the final version. During the editing of this data
file, variables from different versions were put together where
feasible to enable analysis of complete six-year data for as
many variables as possible. Notes elaborating question modifications
are provided in this document. Users should carefully examine the
differences to determine how to conduct analyses. HFVERS can be used
to identify the sample persons who were administered each version.
HFLANG: Language of household family questionnaire
This variable designates the language of conduct for the Family
Questionnaire. Questionnaires were designed to be implemented in a
bilingual (English/Spanish) format so that respondents could to be
interviewed in their preferred language. When it was necessary to conduct
an interview in another language, a translator assisted the interviewer in
administering the questionnaires. These interviews were coded as "Other".
Individual Characteristics
HFA6XCR: In what state or foreign country was -- born?
This recoded variable derived from question A6 in the Household Family
Questionnaire. Place of birth was regrouped into three broad categories in
order to maintain confidentiality of the survey participant.
HFA8R: What is the highest grade or year of regular school -- has completed?
This recoded variable was created from two separate questions A7 and A8.
Question A7 asked "What is the highest grade/year of regular school -- has
ever attended?" Question A8 asked "Did you finish that grade/year?"
HFB1-HFB17: Health insurance coverage questions
Three versions of the health insurance questions were asked during the
survey. The major difference was the time frame referenced for recall
(e.g. "now" versus "in the last month"). Some questions had slight
variations in the wording across versions; others may have been omitted
from one version but added in another. When differences in versions were
slight, the variable was created for the full survey time period. When
differences were significant, version-specific variables were maintained.
The variable HFVERS can be used to identify version. Separate notes are
provided to show differences by version. Because of many changes for this
section of questions, data may not be available for all survey participants
HFB1: Medicare coverage of all SPs in the family
This question differed in the time frame referenced for recall. Versions 1
and 2 read, "Is anyone in the family NOW covered by Medicare?" Versions 3
and 4 read "DURING THE LAST MONTH was anyone in the family covered by
Medicare?"
HFB2: Medicare coverage of specific family members
This question differed in the time frame referenced for recall. Versions 1
and 2 read, "Is -- NOW covered by Medicare?" Versions 3 and 4 read,
"DURING THE LAST MONTH was -- covered by Medicare?"
HFB4: Medicare coverage for hospital bills
This question refers to specific coverage for hospital bills. The versions
differed in the time frame referenced for recall. Versions 1 and 2 read,
"Is -- NOW covered by the part of Medicare that pays for hospital bills?"
Versions 3 and 4 read, "DURING THE LAST MONTH was -- covered by the part of
Medicare that pays for hospital bills?"
HFB5: Medicare coverage for doctor bills
Medicare has an optional feature that requires additional funds and helps
to pay for doctor bills. The different versions varied in the time frame
referenced for recall. Versions 1 and 2 read, "Does --'s Medicare pay for
doctor's bills?" Versions 3 and 4 read, "DURING THE LAST MONTH was --
covered by the part of Medicare that pays for doctor's bills?"
HFB6: Medicaid coverage of any SPs in the family
This question refers to the national program called Medicaid which pays for
health care for persons in need. The different versions varied in the time
frame referenced for recall. Versions 1 and 2 read, "DURING THE PAST 12
MONTHS was anyone in the family covered by Medicaid?" Versions 3 and 4
read, "DURING THE LAST MONTH was anyone in the family covered by Medicaid?"
HFB7: Medicaid coverage for specific persons in the family
This question differs by version in the time frame referenced for recall.
Versions 1 and 2 read, "At any time DURING THE LAST 12 MONTHS was --
covered by Medicaid?" Versions 3 and 4 read, "DURING THE LAST MONTH was --
covered by Medicaid?"
HFB8: Coverage by CHAMPUS, CHAMPVA, the VA, or military health care of any SPs
in the family
This question was not asked on Version 1 of the questionnaire, and had time
frame variations between Versions 2 and 3 and 4. Version 2 reads, "DURING
THE PAST 12 MONTHS was anyone in the family covered by CHAMPUS/CHAMPVA, the
VA or military health care?" Versions 3 and 4 read, "DURING THE LAST MONTH
was anyone in the family covered by CHAMPUS/CHAMPVA, the VA or military
health care?"
HFB9: Coverage by CHAMPUS, CHAMPVA, the VA, or military health care of specific
persons in the family
This question was not asked on Version 1, and had time frame variations
between Versions 2 and 3 and 4. Version 2 reads, "DURING THE PAST 12
MONTHS was -- covered by CHAMPUS/CHAMPVA, the VA or military health care?"
Version 3 and 4 read, "DURING THE LAST MONTH was -- covered by
CHAMPUS/CHAMPVA, the VA or military health care?"
HFB10: Coverage by health insurance plans obtained privately or through an
employer or union for any SPs in the family
This question changed in wording, and in time frame between all versions
versions of the questionnaire. For Versions 1 and 2, the frame of
reference was NOW. For Versions 3 and 4, the frame of reference was DURING
THE LAST MONTH. For Versions 1 and 3 and 4 the introductory statement read,
"We are interested in all kinds of health insurance plans except those that
pay only for accidents." The Version 2 introductory statement read, "We
are interested in all kinds of private health insurance except those that
pay only for accidents."
Version 1 of the question read, "(Not counting Medicare) is anyone in the
family NOW covered by a health insurance plan that pays any part of a
hospital, doctor's, or surgeon's bill?" Version 2 of the question reads,
"(Not counting Medicare, Medicaid, or Veteran's payments) is anyone in the
family NOW covered by a health insurance plan obtained privately or through
a current or former employer or union that pays any part of a hospital,
doctor's, or surgeon's bill?" Versions 3 and 4 of the question read, "(Not
counting Medicare, Medicaid, or Veteran's payments) DURING THE LAST MONTH
was anyone in the family covered by a health insurance plan obtained
privately or through a current or former employer or union that pays any
part of a hospital stay or routine doctor's care? Include membership in a
health maintenance organization."
HFB11 and HFB11A-HFB11E: Coverage by health insurance plans obtained privately
or through an employer or union for specific family members
Questions HFB11A-HFB11E follow from the lead-in question HFB11. The time
frame for all of the questions is dependent upon the version of the lead-in
question. Version 1 read, "Is -- NOW covered by a health insurance plan?"
Version 2 read,"Is -- covered by a health insurance plan?" Versions 3 and
4 read, "During the LAST MONTH was -- covered by a health insurance plan
obtained privately or through an employer or union?" Many of the questions
that follow are version-specific, as noted.
HFB11B: Coverage of routine doctor's care from health insurance plans obtained
privately or through an employer or union
This question was asked only on Versions 3 and 4 of the questionnaire.
HFB11C: Dental care coverage of health insurance plans obtained privately or
through an employer or union
This question was not asked in Version 1 of the questionnaire.
HFB11D: Insurance plan from former employer or union rather than obtained
privately
This question was asked only on Version 3 of the questionnaire.
HFB11E: Coverage of doctor's or surgeon's bills for operations from health
insurance plans obtained privately or through an employer or
union
This question was asked only on Versions 1 and 2.
HFB12: Has --- ever been refused health insurance or limited in the kind of
insurance coverage
This question was asked only on Versions 3 and 4 of the questionnaire.
HFB14AA-HFB14BI: Reasons for not having health insurance
The response categories for this question differed significantly by
version and were therefore all included. A respondent could give multiple
responses for this question. HFB14AA and HFB14AH were possible responses
in Version 1. HFB14BA-HFB14BI were possible responses in Version 2.
HFB16A and HFB16B: Main reason -- not covered by health insurance
These were retained as separate variables because the response categories
for the question differed significantly by Version. Categories for question
16A were included in Versions 1 and 2. Categories for question 16B were
included in Versions 3 and 4.
HFB17: Health insurance that pays any part of dental care
This was asked only on Version 1 of the questionnaire. The question for
variable HFB11C (Versions 2,3 and 4) also dealt with dental care coverage,
though had different criteria in its lead-in question.
HFC2S: How much (does --'s mother/do you) weigh? (pounds)
This variable was created from question C2 to standardize responses to
pounds. For responses in kilograms the conversion factor 2.2046
kilograms/pound.
HFC3S: How tall (is --'s mother/are you)? (inches)
This variable was created from question C3 to standardize responses to
inches. For responses in centimeters, the conversion factor was 0.3937
centimeters/inch.
HFC4S: How much (does --'s father/do you) weigh? (pounds)
This variable was created from question C4 to standardize responses to
pounds. For responses in kilograms the conversion factor 2.2046
kilograms/pound.
HFC5S: How tall (is --'s father/are you)? (inches)
This variable was created from question C3 to standardize responses to
inches. For responses in centimeters, the conversion factor was 0.3937
centimeters/inch.
HFC7S: How long has -- lived at this address? (weeks)
This standardized variable was created from the two-part question (quantity
and unit) C7 using the conversion factors 4.3 weeks/month and 52
weeks/year. If the response was "whole life", then the time was converted
to weeks based on age at interview (HSAGEIR and HSAGEU).
HFC8S: How long has -- lived in this (city/town/area)? (weeks)
This variable was created from the two part question (quantity and unit) C8
using the conversion factors 4.3 weeks/month and 52 weeks/year. If the
response was "whole life", then the time was converted to weeks based on
age at interview (HSAGEIR and HSAGEU).
HFD1, HFD9R, HFD10R, HFD12: Questions on occupation of the Family Reference
Person (FRP)
These questions were asked about the occupation of FRPs only if they were
not sample persons. FRPs who were also sample persons responded to
questions on occupation in the Household Adult Questionnaire (HAS1-HAS29).
For additional information on the FRP from the Family Questionnaire, see
variables that begin with the prefix HSH.
HFD9R: Business or industry of Family Reference Person
Classification of business or industry based on categories defined by the
U.S. Bureau of Census in 1980 (U.S. Bureau of the Census, 1981).
HFD10R: Occupation of Family Reference Person
Classification of occupation based on categories defined by the U.S. Bureau
of Census in 1980 (U.S. Bureau of the Census, 1981).
HFD12: Class of worker Family Reference Person (FRP)
The category armed forces was added in Versions 3 and 4. In the earlier
version, armed force status can be ascertained from HFD9. In Versions 3
and 4,FRPs who were in active military service skipped out of the detailed
occupational questions in this section.
HFE1: Year house was built
A small number of sample persons were unable to answer this question
because they reported living in mobile homes. Since there was not category
for this response, they were included as blank but applicable.
HFF2R: Total number of persons who smoke cigarettes in the home
This total was derived by counting the number of persons recorded
as smoking in the home (questions F1 and F2).
HFF4-HFF8: Food Insufficiency
The intent of these questions was to capture insufficient food availability
at the family level due to lack of money and/or other resources as answered
by the respondent to the Family Questionnaire. Related questions answered
by individuals or their proxies were asked following the 24-hour dietary
recall in the MEC (See NHANES III Dietary Data File).
HFF6: Reasons for no food or money to buy food
More than one response could be answered yes for question F6. Textual
responses to this question were reviewed and coded into existing categories
HFF6A-HFF6C where possible. Remaining responses which could not be coded
back into existing questions, such as health reasons, are included in HFF6D
as "Other."
HFF7 and HFF8: Size of meals cut
Questions F7 and F8 were asked only in Versions 3 and 4. The variable
HFVERS can be used to select only those records for sample persons who were
asked these questions. The purpose of the questions was to ascertain
information on cutting back or skipping meals as a coping strategy for not
having enough food in the family.
HFF9: WIC participation in family
WIC is the Special Supplemental Food Program for Women, Infants, and
Children administered by the U.S. Department of Agriculture. Question F9
was asked also of individuals or their proxies during the interviews that
took place in the MEC and home examinations. (See NHANES III Examination
Data File)
HFF10 and HFF11: Food Stamp Program participation in family
Food stamps refers to the Food Stamp Program administered by the U.S.
Department of Agriculture.
HFF12A-HFF17B: Types of family income
Questions F12 through F17 were structured similarly. The first part of the
question asked whether any family member received a certain type of income.
The second part of the question indicated the recording of the line
number(s) for the person(s) who received the income. Because the line
number from the Household Screener Composition Table will not be released,
the second part of the question will contain only the response for the
specific sample person to which a record refers.
HFF13A: Social Security or Railroad Retirement payments in family
The time frame as well as the wording changed in this question. In
Versions 1 and 2, the frame of reference was THE PAST 12 MONTHS. In
Versions 3 and 4, the frame of reference was the LAST MONTH. Versions 1 and
2 read "DURING THE PAST 12 MONTHS did any member of the family receive any
Social Security payments?" Version 3 and 4 read "DURING THE LAST MONTH did
anyone in the family receive any Social Security or Railroad Retirement
payments?"
HFF13DA-HFF13DB: Reason for receiving Social Security or Railroad Retirement
payments
The response categories for question F13d changed significantly between
Versions 1 and 2 and Versions 3 and 4 so that the question was retained by
version.
HFF13E: Another reason for receiving Social Security payments
In Versions 1 and 2, respondents were asked to state another reason that
they were receiving Social Security.
HFF14A: Supplemental Security Income payments in family
The time frame changed in this question. In Versions 1 and 2, the frame of
reference was THE PAST 12 MONTHS. In Versions 3 and 4, the frame of
reference was the LAST MONTH. Versions 1 and 2 read "DURING THE PAST 12
MONTHS did anyone in the family receive SSI (Supplemental Security Income)
payments from the U.S./Federal government?" Version 3 and 4 read "DURING
THE LAST MONTH did anyone in the family receive SSI (Supplemental Security
Income) payments from the Federal government?"
HFF14B: Supplemental Security Income payments to SP
The time frame changed in this question. In Versions 1 and 2 the frame of
reference was THE PAST 4 MONTHS. In Version 3 and 4 the frame of
reference was THE LAST MONTH. Versions 1 and 2 read"DURING THE PAST 4
MONTHS, did -- receive SSI payments from the U.S./Federal government?"
Version 3 and 4 reads "DURING THE LAST MONTH, did -- receive SSI payments
from the Federal government?"
HFF14D: Supplemental Security Income payments from State or local welfare
office
Question F14d was asked only in Versions 1 and 2 of the questionnaire. The
variable HFVERS should be used to select only those records for sample
persons who were asked this question.
HFF15A-HFF16B: Pension or disability payments- Public assistance or welfare
payments
Questions F15a-F16b were asked only in Version 3 and 4. The variable HFVERS
should be used to select only those records for sample persons who were
asked this question.
HFF16D-HFF16E: Aid to Families with Dependent Children payments
Questions F16d and F16e were asked only in Versions 2 and 3 of the
questionnaire. The time frame was modified between the last two versions.
For question F16d, Version 2 read "Does anyone in the family NOW receive
assistance through the "Aid to Families with Dependent Children" Program,
sometimes called "AFDC" or "ADC"?" Version 3 and 4 read "DURING THE LAST
MONTH did anyone in the family receive "Aid to Families with Dependent
Children", sometimes called AFDC or ADC?" For question F16e, Version 2
read "Is -- included in the AFDC assistance payment?" Version 3 and 4 read
"DURING THE LAST MONTH, did -- receive "Aid to Families with Dependent
Children," sometimes called AFDC or ADC?"
HFF17A-HFF17B: Income from any other source
These questions were asked only in Version 3. The variable HFVERS should
be used to select only those records for sample persons who were asked
these questions.
HFF19R: Family income during last 12 months
The response categories were changed between Versions 1 and 2 and Version 3
and 4 of the questionnaire. In Versions 1 and 2, the response categories
for question F19 ended with the category "$50,000 and over" (coded 27) In
Version 3 and 4, the categories were expanded to include four that were
over $50,000.
27 $50,000-$59,000
28 $60,000-$69,000
29 $70,000-$79,000
30 $80,000 and over
Variable HFF19R is a recoded variable based on response categories for
Versions 1 and 2. For comparability, responses to categories over $50,000
in Versions 3 and 4 were collapsed back into the single category "$50,000
and over."
HFF20R: Family income during last month
Respondents were allowed to indicate that their family income during the
last month was the annual income reported in question F19 divided by 12.
For these responses, the monthly income was imputed by dividing the
midpoint of the range selected in question F19 by 12.
The response categories were changed between Versions 1 and 2 d Version 3
of the questionnaire. In Versions 1 and 2, the response categories for
question F20 ended with the category "4,000 and over" (coded 20) In
Version 3 and 4, the categories were expanded to include:
20 $4,000-$4,999
21 $5,000-$5,999
22 $6,000-$6,999
23 $7,000 and over
Variable HFF20R is a recoded variable created using the response categories
for Versions 1 and 2. For comparability, responses in Versions 3 and 4 to
the expanded categories were collapsed back into the single category
"$4,000 and over."
Family Reference Person
HFHSEQN: Sequence number for Family Reference Person (FRP)
This variable is the unique identifier for the family reference person
(FRP). The FRP was designated during the Screener interview as the person
17 years of age or older who owned or rented the dwelling unit. If no one
owned or rented the unit, then the family reference was the first family
member mentioned by the Screener respondent who was 17 years of age. The
FRP was established in order to arrange household members into family
units. In earlier NHANES and in parts of the NHANES III interview
questionnaires, the FRP was referred to as "the head of the household."
(For more details, see the chapter on "Administering the Interview" in the
NHANES III Interviewer's Manual, U.S DHHS, 1996.)
HFHAGER: Age of the Family Reference Person (FRP)
Question A3 of the Family questionnaire asked the age (transcribed from the
Screener) of the FRP and of each sample person. See HSAGEIR and HSAGEU for
the age at interview (Screener Interview) of sample persons.
HFHSEX: Sex of the Family Reference Person (FRP)
Question A4 of the Family questionnaire asked the sex of the FRP and of
each sample person. See HSSEX for the sex of sample persons.
HFHFIPR: Place of birth Family Reference Person (FRP)
This recoded variable was derived from question A6 in the Household Family
Questionnaire. Place of birth was regrouped into three broad categories in
order to maintain confidentiality of the survey participant. See HFA6XCR
HFHEDUCR: Highest grade completed Family Reference Person (FRP)
This recoded variable was created from two separate questions A7 and A8 in
the Family questionnaire. These questions were asked of all sample persons
as well as of the FRP. Question A7 asked "What is the highest grade/year of
regular school -- has ever attended?" Question A8 asked "Did you finish
that grade/year?" Persons who did not complete the grade answered in A7,
were coded to having completed one previous grade. See HFA8R for completed
years of education for sample persons.
HFHEMPL: Employment status of Family Reference Person (FRP)
This derived variable combines responses from questions D2 and D3 of the
Family questionnaire for FRPs who were not sample persons, and from
questions S1 and S2 of the Household Adult questionnaire for FRPs who were
also sample persons. For more detail on the occupation of the FRP see:
variables HFD1, HFD9R, HFD10R and HFD12.
HFHMRST: Marital status of Family Reference Person (FRP)
Question A12 asked the marital status of the FRP and the sample person.
See HFA12 for the marital status of sample persons.
HFHMLSV: Military service of Family Reference Person (FRP)
Question A13 of the Family questionnaire asked whether the FRP or the
sample person ever served in the Armed Forces. Persons who were serving in
the military at the time of the interview, but living at home, were
permitted to be only Family Reference Persons, not sample persons. See
HFA13 for the military service of sample persons.
HFRELR: Relationship of respondent to the Family Reference person
No other information, except for age (HFAGERR), is available on respondents
to the Family Questionnaire who were not sample persons or family reference
persons.
HFAGERR: Age of respondent
Ages of 90 years or greater were recoded into a single category of 90+
years to help protect the confidentiality of survey participants.
Household Youth Questionnaire
HYA7S: Weight at birth
This variable was created from the original question A7 using the
conversion factor 28.349 grams/ounce (0.03527 ounces/gram) and 16
ounces/pound (0.00220 pounds/kilogram).
HYA9R: Approximate weight at birth
This variable is created by combining responses to questions HYA7S, HYA8
and HYA9. The exact birth weights reported in HYA7S were categorized into
the 3 categories: less than 2500 grams, 2500 grams through 4100 grams, and
more than 4100 grams. The responses to HYA8 and HYA9 were used when the
respondent did not know the exact birth weight. If the response in A8 was
less than 2500 grams it was coded as 1 in HYA9R. If the response was more
than 2500 grams in A8 and less than 4100 grams in A9, then it was coded as
2 in HYA9R. If the response was more than 2500 grams in A8 and more than
4100 grams in A9 then it was coded as 3 in HYA9R.
HYB3S: First fed something other than breastmilk or water
This question was only asked in Phase 2 of the survey. It is important to
note that although the skip pattern for HYB2 indicates that all persons who
answered "yes" were then asked HYB3S, this is only true for persons
interviewed in Phase 2. The variable was created from the two part
question (number and unit) B3 using the conversion factors 7 days/week
and 30.4 days/month.

This variable was created from the original question B18 using the
conversion factor 0.3937 inches/per centimeter. For persons 12-16 years,
this question was asked during the body measurements exam in the Mobile
Examination Center. Refer to the documentation for the NHANES III
Examination Data File, body measurements component, for these data.
HYB19S: Reported weight without clothes
This variable was created from the original question B19 using the
conversion factor 2.2046 pounds/kilogram. For persons 12-16 years, this
question was asked during the body measurements exam in the Mobile
Examination Center. Refer to the documentation for the NHANES III
Examination Data file, body measurements component, for these data.
HYC1-HYC50: Motor & Social Development
These questions were adapted from the Denver Developmental Screening Test
(Frankenbury, 1985).
HYC2: Age check item for questions on motor and social development
In Phase 1 the age in months at Screener interview (HSAITMOR) was used to
determine the check item response for this section of questions. In Phase
2 the age in months at time of the household youth interview (HYAITMO) was
used. These ages may or may not be different for all sample persons.
HYD12S: Number of months since health problem first noted
This variable was created from the two part question (number and unit) D12
using the conversion factor 12 months/year.
HYE2AS: Age in months first had rheumatic fever/rheumatic heart disease

using the conversion factor 12 months/year.
HYE7AS: Age in months first had hypertension or high blood pressure
This variable was created from the two part question (number and unit) E7A
using the conversion factor 12 months/year.
HYE7BS: Age in months first had high blood cholesterol
This standardized variable was created from the two part question (number
and unit) E7B using the conversion factor 12 months/year.
HYE17S: Number of months last tested
This standardized variable was created from the two part question (number
and unit) E17 using the conversion factor 12 months/year.
HYE20S: Number of months last treated
This standardized variable was created from the two part question (number
and unit) E20 using the conversion factor 12 months/year.
HYE23S: Number of months last DPT or tetanus shot
This standardized variable was created from the two part question (number
and unit) E23 using the conversion factor 12 months/year.
HYF4S: Number of days since --'s last visit to a dentist or dental hygienist
This variable was created from the two part question (number and unit) F4
using the conversion factors 7 days/week, 4.3 weeks/month, and 52
weeks/year.
HYH7S: Age in months when had first ear infection or earache
This variable was created from the two-part question (quantity and unit) H7
using the conversion factor 12 months/year.
HYJ3S: Number of months -- attended this kind of center or school
This variable was created from the two part question (number and unit) J3
using the conversion factor 12 months/year.
HYK1A: Has -- taken any vitamins or minerals in the past month?
This was the lead-in question for a series of questions on vitamins and
minerals. If the response to this question was yes, the respondent or
proxy was asked the number of supplements they took. For each supplement
taken the respondent was asked about how often the supplement was taken,
the dosage, and duration of use. The user should be aware, however, that
there were respondents who reported taking supplements, but did not answer
some or all of the remaining questions about the supplements. Although
this lead-in question was designed to determine whether the respondent was
using any vitamin or mineral supplements, respondents often reported taking
other types of dietary supplements such as formula diets, sports drinks,
herbs, plants and similar products, amino acids, bee pollen, lipotropics,
fish oils, and enzymes. This information was retained along with the
vitamin/mineral supplements. However, since the question did not ask
specifically about the use of other nonvitamin/nonmineral dietary
supplements, the frequency with which these products were reported should
not be considered to be nationally representative. It should also be noted
that all of the information from the section does not appear in this data
file; additional variables including supplement formulations will be
released as a separate data file.
HYK1B: Has -- taken or used any prescription medicines in the past month?
This was the lead-in question for a series of questions on prescription
medicines. If the response to this question was yes, the respondent or
proxy was asked the number of prescription medicines they took. For each
prescription medicine taken the respondent was asked to describe the health
problem for which they took the medicine, and how long they had been taking
the medicine. The user should be aware, however, that there were
respondents who reported taking prescription medicines, but were only able
to answer some of the remaining prescription drug questions. Prescribed
vitamin or mineral supplements (e.g., fluoride, iron, and prenatal
vitamins) originally reported as prescription drugs were moved to the
vitamin/mineral section. These could, in fact, be considered either a drug
or a supplement such as calcium-based antacid, calcitrol, and potassium.
It should also be noted that all of the information from the section does
not appear in this data file; additional variables including drug
formulations will be released as a separate data file.
HYK2A: Number of vitamins/mineral supplements reported
This variable represents the total number of different supplements reported
by the respondent or proxy. For each supplement reported, the interviewer
asked to see the supplement container in order to record the name of the
product and the manufacturer. If the container was not available, the
interviewer probed for this information. Supplements that appear to be
identical or duplications of another reported product are usually different
forms (e.g., tablet vs. liquid) of the same product.
HYK2B: Number of prescription drugs reported
This variable represents the total number of different prescription
medicines reported by the respondent or proxy. For each medication
reported, the interviewer asked to see the medication container in order to
record the name of the product. If the container was not available, the
interviewer probed for this information. Reports of non-prescription drug
use, such as antacids, were deleted. However, calcium-containing antacids
were moved to the vitamin/mineral supplements section. Medicines that
appear to be identical or duplications of another reported product are
usually different forms (e.g., tablet vs. liquid) of the same product.
HYK3CG, HYK3CH, HYK3CI, HYK3CJ, HYK3CK, HYK3CL, HYK3CM, HYK3CN, HYK3CO, HYK3CP:
Certainty index codes
A certainty index was derived as a means of evaluating how closely the
reported name of a dietary supplement matched a standard or brand name
product which, in turn, was used for determining nutrient intakes. Each
reported dietary supplement was assigned a certainty code. The index
consists of six levels ranging from the highest degree of certainty that
the reported supplement was correctly identified (code=1) to no level the
lowest degree of certainty (code=6) , i.e., no match could be made between
the reported supplement and a standard supplement. More specifically, the
code of 1 was used when the respondent provided enough information about
the product that it exactly matched a specific brand name supplement. A
code of 2 was applied when the product name was partially incomplete or
misspelled, but generally identifiable. A code of 3 was used for cases
where a single nutrient supplement, such as calcium, was reported without
the concentration. A code of 4 was applied when a generic type of
supplement was reported such as "children's chewable multivitamins" or
"iron vitamins" when it was not possible to identify the specific brand
name or nutrient composition. A code of 5 was assigned to supplements that
could not be readily identified although they were thought to be dietary
supplements such as "Shaklee vitamins" or "Diamite nutritional". A code of
6 was used for products that could not be identified.
HYK3DG, HYK3DH, HYK3DI, HYK3DJ, HYK3DK, HYK3DL, HYK3DM, HYK3DN, HYK3DO, HYK3DP:
Product class
Each reported dietary supplement was categorized into one of 7 broad
product-type classes according to general nutrient composition. The first
five classes (1-5) were assigned only to vitamin and/or mineral
supplements. The remaining two classes (6 and 7) were assigned to other
dietary supplements including amino acids, lipotropics, herbs, plants and
other nontraditional dietary supplements. Dietary supplements that also
contained a vitamin and/or a mineral (e.g., ginseng and bee pollen with
vitamin E) were assigned to class 6, whereas those that did not include
vitamins or minerals were assigned to class 7.
HYK6SG, HYK6SH, HYK6SI, HYK6SJ, HYK6SK, HYK6SL, HYK6SM, HYK6SN, HYK6SO, HYK6SP:
How often did -- take -- in the past month?
These variables were created for each reported dietary supplement from the
two-part (number and unit) question K6, and indicate how frequently each
supplement was taken in the past month. The conversion factors used for
days and weeks were 30 and 4, respectively. While frequency of use was
standardized to "month," new supplement users may have been taking the
supplement for less a month at the time of the interview. Analysts,
therefore, may want to examine duration (HYK8S variables) as well as
frequency of use.
HYK8SG, HYK8SH, HYK8SI, HYK8SJ, HYK8SK, HYK8SL, HYK8SM, HYK8SN, HYK8SO, HYK8SP:
How long has -- been taking this product? (months)
This variable was created from the two-part (number and unit) question K8,
and indicates the long-term duration of use. The conversion factor was 12
months/year. When supplements were reported as prescription drugs and
then moved as part of the data editing process (see note for variable HK1A)
much of the information was not directly transferable. For example,
categories for duration of taking drugs (HYK12S variables) did not
always match those listed for the corresponding question for
vitamin/mineral supplements (HYK8S variables). Responses reported in weeks
were rounded to the nearest month, whereas response in months and years
were transferred directly.
HYK9DG, HYK9DH, HYK9DI, HYK9DJ, HYK9DK, HYK9DL, HYK9DM, HYK9DN, HYK9DO:
Primary drug class code
Up to three drug class codes were assigned for each reported prescription
medication. These 4-digit codes were supplied by the Product Information
Branch, Center for Drug Evaluation and Research at the U.S. DDHS Food and
Drug Administration. The version of these codes that was used was last
updated in October 1994. The primary drug class code assignment was based
on the known drug action. For example, all cardiovascular drugs that were
beta-adrenergic blocking agents were assigned the drug class code 0512
(beta blockers). See Appendix 2 for listing of codes.
HYK9EG, HYK9EH, HYK9EI, HYK9EJ, HYK9EK, HYK9EL, HYK9EM, HYK9EN, HYK9EO:
Secondary drug class code
This variable contains the second drug class codes for each prescription
drug reported. If medical condition for which the medication was used (as
reported in question K11) was different than the known drug action, then a
secondary drug class code was entered. For example, a cardiovascular drug
that was a beta-adrenergic blocking agent was assigned the drug class code
0512 (beta blocker) as the primary drug code, and a secondary drug class of
0502 (antiarrhythmic). If the reason provided did not relate to any of the
known actions of the drug, then only the medication-specific (primary)
class code was assigned. See Appendix 2 for listing of codes.
HYK9FG, HYK9FH, HYK9FI, HYK9FJ, HYK9FK, HYK9FL, HYK9FM, HYK9FN, HYK9FO:
Tertiary drug class code
This variable contains the tertiary drug class codes for each prescription
drug reported. If medical condition for which the medication was used (as
reported in question K11) was different than the primary drug class, then a
secondary, and tertiary drug class code was entered. For example, a
cardiovascular drug was assigned the drug class code 0512 (beta blocker) as
the primary drug code, a secondary drug class code of 0502
(antiarrhythmics), and a tertiary code of 0506 (antihypertensives). If the
reason provided did not relate to any of the actions of the drug, then only
the medication-specific class code (primary) was assigned. See Appendix 2
for listing of codes.
HYK11AG, HYK11AH, HYK11AI, HYK11AJ, HYK11AK, HYK11AL, HYK11AM, HYK11AN, HYK11AO:
ICD-9-CM code
ICD-9-CM codes were used to classify the medical conditions reported in
question K11 for each prescription drug reported. Conditions were coded to
the forth digit ICD-9-CM level of specificity except in those cases where
the three digit ICD-9-CM code is the highest level of specificity. Some
conditions where no appropriate code was available in the Classification of
Diseases and Injuries ICD-9-CM codes, were coded using V Codes -
Supplementary Classification of factors Influencing Health Status and
Contact with Health Services. See Appendix 3 for listing of codes.
HYK12SG, HYK12SH, HYK12SI, HYK12SJ, HYK12SK, HYK12SL, HYK12SM, HYK12SN, HYK12SO:
For how long have -- been taking this medicine? (days)
This variable was created from the two-part (number and unit) question K12
(standardized in days). The conversion factors for weeks, months, and
years were 7, 30, and 365, respectively. For medicines originally reported
as supplements and moved in the data editing process, duration of use could
not always be directly transferred. The categories for duration of
supplement use in question K8 did not match those listed for the
corresponding question under prescription medicines (K12). A response of
"less than one month" in K8 was changed to blank but applicable (8-fills)
in K12 for medicines that were originally recorded as supplements.
HYM3: Quality of interview
Interviewers determed whether or not the one or more sections of the
Household Youth Interview was possibly unreliable. This determination was
subjective and based on a number of factors including the relationship of
the respondent (proxy) to the sample person (HYM1), mental competency of
the respondent (proxy), etc. Because there was norecord of the
sections that were possibly unreliable, all interviews were retained.
