OBJECTIVE: To determine factors affecting self-rated health among the non-institutionalized elderly in Japan. METHODS: In 20 municipalities in Japan, 6,094 persons aged 65 years and older who were not institutionalized were selected at random. A questionnaire survey was conducted from September through November 2000. The distribution of self-rated health was rated in terms of dependent variables, with odds ratios and their 95% confidence intervals calculated using unconditional logistic models. RESULTS: Of the study population, 5,565 persons (91.8%) responded to the survey. Of the respondents, 64.4% answered that they were healthy, while 28.8% were not. The necessity for periodical visit to hospitals and clinics, and lowering of the activity of daily living greatly lowered self-rated health. Compared with those who were 85 years of age or older, a high health status was observed among those aged between 75 and 84 years, but not those aged 65 to 74 years. Those who tried to have exercise periodically, who had a vice-leadership role in a group, who joined social activities, who lived what they considered a worthwhile life, and who had positive positive activities in daily life, had high levels of self-rated health. Joining social activities for passive reasons elevated the health as well as joining for active reasons such as "because it is fun." CONCLUSION: Even if the reason is passive, joining social activities may elevate the self-rated health levels of elderly people.
