Self-rated health and self-assessed change in health in elderly men and women--a five-year longitudinal study.

The purpose of the present investigation was two fold: (1) to examine how men and women self-rate their health as they age from 75 to 80 yr and how they assess the change in their health over the five year period; and (2) to ascertain how self-assessed change in health over the follow-up period corresponded to the difference in self-ratings of health between the assessments performed at baseline and at follow-up. The study was part of the Evergreen-project with the study group comprising all inhabitants born in 1914 (N = 388) living in Jyväskylä, central Finland. At baseline, 93.4%, and at follow-up, 93.3%, of those who were eligible participated in the interview. Self-rated health, when asked using the same questions, did not change at follow-up compared to baseline. However, nearly half of the follow-up group reported that their health had become worse over the five year period. Gender differences in self-rated health were not found, although women reported more often than men that their health had become worse and some of the men said their health had become better. It is concluded that self-rated health seems to be age-adjusted; elderly people who say their health has become worse as they age actually self-rate their health as the same or better than before.
