Objective:
To determine the existence of a relationship between physical activity and depressive symptoms in community-dwelling elders.
Method:
This is a cross-sectional, population-based study, which included 379 community-dwelling elders from Novo Hamburgo, state of RS, Brazil. The level of physical activity was estimated using the International Physical Activity Questionnaire and depressive symptoms were diagnosed according to the Yesavage Geriatric Depression Scale. The association between the level of physical activity and depressive symptoms was analyzed by logistic regression.
Results:
A tendency towards a lower prevalence of depressive symptoms was observed in individuals with higher levels of physical activity, both in the sample as a whole as well as among men, but not among women (p for linear trend 0.04, 0.03 and 0.36, respectively). The odds ratio of the presence of depressive symptoms in the very active group as compared against that of the insufficiently active group was 0.32 (95% CI: 0.12-0.86) for men and 0.76 (95% CI: 0.39-1.46) for women.
Conclusion:
In this population of aged individuals, more intense physical activity is related to a lower prevalence of depressive symptoms. As shown by gender stratification, physical activity is inversely related to depressive symptoms in men, albeit not in women.
