Physical activity and self-rated health among 55- to 89-year-old Dutch people.

The aim of this study was to examine the effects of physical activity and the possible mediating role of perceived physical self-efficacy (PPSE) on self-rated health (SRH) in the 55- to 89-year-old Dutch population. The data are based on a structured interview carried out in a random sample of 120 subjects--60 men and 60 women with the average ages of 69 and 71 years, respectively--in Sassenheim, the Netherlands, as a pilot study of the Longitudinal Aging Study Amsterdam (LASA). The results of linear multiple regression analyses showed that physical activity was a significant predictor of self-rated health. Moreover, the results supported the role of PPSE as a mediator in the association between physical activity and self-rated health status even when age, gender, and chronic diseases were controlled. These findings suggest that in the elder population, increasing perceived physical self-efficacy may be more important for perceived health than raising the level of physical activity.
