HOME EXAMINATION, INTERVIEW The Home Examination interview was administered at the homes of examinees aged 2-11 months and those aged 20 years and older who were unable to travel to the mobile examination center (MEC). The interview included sections similar to those found in other MEC questionnaires: infant food frequency, cognitive function, selected conditions/medicine, vitamin and mineral usage, tobacco use, and reproductive health. Data from examinations conducted in the home (body measurements, physical function, spirometry, and venipuncture) have been included with the corresponding examination and laboratory data; therefore, they have not been included here. Items from the MEC Adult Questionnaire and the Home Examination interview can be combined for analysis; however, there may be slight differences in the questions the way in which they are administered. For example, the reproductive health section in the interview during the Home Examination was shorter, and the skip patterns were not the same. For analysis of the Home Examination interview data alone or for combined MEC and Home Examination questionnaire data, the MEC+home Examination weights (WTPFHX6) should be used. Separate sample weights were not created for the Home Examination. For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). The interview during the Home Examination was brief in comparison to those conducted in the MEC. Like the MEC questionnaires, certain sections were asked only of specific age and gender groups. For instance, reproductive health questions were asked only of females aged 20 years and older. Cognitive function questions were asked of examinees age 60 years and older. Tobacco use was asked of examinees aged 20-60 years. The infant food frequency was asked of a parent or other adult in the household member for each child aged 2-11 months. Data processing and editing were performed for the consistency of responses within the sections of the questionnaire. Notes have been provided for variables that were standardized or recoded or those that require additional comments.
