RESUMO
OBJECTIVE: To evaluate the prevalence of leisure-time physical activity and episodes of mood alteration in a population-based sample of adults, and its relation with gender. METHOD: This is a cross-sectional population-based study with young adults aged between 18 and 35 years old. Sample selection was performed by clusters. The practice of physical activity was evaluated through the International Physical Activity Questionnaire (IPAQ), whereas mood disorders were evaluated using a short structured diagnostic interview-the Mini International Neuropsychiatric Interview (MINI) for DSM-IV and ICD-10 psychiatric disorders. LIMITATION: Causal inferences are limited due the study׳s design. RESULTS: Sample consisted of 1953 young adults. The prevalence of leisure-time physical activity and of depressive episodes in the total sample was 25.3% and 17.2%, respectively. The prevalence of activity amongst men was 1.18 (CI 95% 1.18-1.32) times higher than in the women׳s group, whereas depression was 1.87 (CI 95% 1.41-2.47) times more prevalent amongst women than men. The prevalence of physical activity was not different between women (p=0.287), nor between men (p=0.895) regarding the presence of mania/hypomania episode. CONCLUSION: The prevalence of physical activity and depression was different concerning gender. The prevalence of physical activity is lower amongst women, whereas the prevalence of depression is higher amongst women when compared to men.
