FACTORS ASSOCIATED WITH SELF-RATED HEALTH FOR NON-INSTITUTIONALIZED AGED PERSONS

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 pesons (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 halth. 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.
