Self-rated health and associated factors among men of different ages.

The connections of certain clinico-physiological indicators of health state, chronic diseases, felt symptoms, and psychic well-being with self-rated health were studied among men of different ages as a part of the more extensive research project Jyväskylä Studies on Functional Aging. Study population was selected by using systematic random sampling among men aged 31 to 35, 51 to 55 and 71 to 75 years in the city of Jyväskylä. Log-linear and logit models as well as regression and structural equation models within the framework of LISREL were used as methods of analysis. The associations between general self-rated health and the explanative variables were different in different age groups: In the youngest age group self-rated health was best explained by symptoms and index of physical fitness; among the middle-aged by symptoms and psychic well-being; and among the oldest by chronic diseases. The results suggest that self-rated health belongs to the important indicators of health, and more attention should be paid to it both in research and in medical practice.
