[Development in health status of a group of retired subjects in the Paris region according to their practice of physical activity].

The relation between physical activity and health among retired people aged 65 and over was studied in a sample of 993 subjects, men and women, living at home in the Paris area and randomly selected from a pension fund roll. In 1982-1983 (T1), 627 subjects were interviewed. Five years later (T2), 464 subjects participated in the survey. Health was measured by the number and types of impairments and disability. The incidence of cardiorespiratory impairment and the incidence of disability were weaker among subjects with physical activity in T1 than among subjects without physical activity. These findings were unchanged after adjustment for age, sex, socioeconomic status, cigarette smoking, body mass index, uncomfortable housing, living alone and hard physical conditions during working life. This result suggests the beneficial effect of physical activity in promoting health among retired people aged 65 and over.
