Self-assessments of health are important because they appear to be good predictors of future physical health. To examine age differences in self-reports of health, the self-ratings of 149 adults (53.8 percent over 65 years of age; 46.2 percent 64 or younger; average age 57.1) were compared. Subjects were elderly participants in a community exercise program (N=45), attendees of a center for the aging (N=33), and neighborhood residents (N=70) who completed questionnaires on attitudes toward their own health, mood, disability, and specific medical problems. Analysis of results showed that the respondents tended to rate themselves as healthy; 49.3 percent stated they had no chronic health problems, and 79.5 percent stated they had not been sick in the last 2 months and had not had an accident or an injury. The most troublesome problems reported were high blood pressure and arthritis. There were no significant differences between the ratings of exercise program participants and nonparticipants or between ratings of women and men. Younger respondents, however, rated their health more highly than did older respondents. (MCF)
