The present study aims at identifying characteristics of non-respondents in a longitudi nal comprehensive observation of community elderly residents . The subjects were 422 elderly adults (197 males, 225 females) living at home in Koganei City, Tokyo. They res ponded to a comprehensive health survey in 1976 when they were aged from 69 to 71 years.They were followed up in 1981, 5 years later. Out of the 422 elderly, 213 responded to the follow-up survey (the respondents). One hundred and nineteen did not respond (the nonrespondents), although they were alive and living at home. The 116 non-respondents were interviewed at home. A one-fourth random sample of them were also examined medically at home. The differences were observed between the respondents and the non-respondents concerning the variables both at ages 69-71 and 74-76. The results obtained were as follows: 1) No difference was found between the respondents and the non-respondents as for the variables at age 69-71 for males. On the other hand, levels of education, activities of daily living (ADL), social activities, and memory as measured by Benton Performance test at age 69-71 were significatly lower in the non-respondents than in the respondents for females. 2) Concerning the variables at age 74-76, the non-respondents had significantly lower levels of locomotion and serum albumin, and a significantly higher rate of lying ill at home for more than a week during the year prior to the the survey in both sexes. In males, left axis deviation in electrocardiograms was found significantly more commonly in the nonrespondents than in the respondents. Only females showed significantly lower levels of ADL, grip, social activities, and memory, and, further, significantly higher blood pressures and a higher rate of admission to hospital during the year prior to the survey in the non-respon dents. It could thus be concluded that physical, psychological and social deteriorations with advancing age were more pronounced in the non-respondents than in the respondents.
