Abstract Objective : To analyze the association betwe -en physical activity during leisure time and common mental disorders among residents in urban areas of Feira de Santana City, Bahia. Methods : A cross-sectional study was conducted in a representative sample from the urban population. A sample of 3,597 individuals aged 15 years or older (71.4% female) was studied. A questionnaire gathered information about sociodemogra -phic information, self-reported diseases, screening for mental disorders, lifestyle habits and physical activity during leisure time. To evaluate common mental disorders (CMD) the Self-Reporting Questionnaire (SRQ-20) was used. To analyze the associa-tion between leisure physical activity (ac-tive/inactive) and CMD, prevalence ratios (PR) and their respective 95% confidence intervals were estimated by using multiple logistic regression and the Delta method. Results : We found a frequency of 27.7% of individuals who were active during leisure time. The prevalence of CMD was lower among those active in leisure time, after adjustment by sex, age, income, education, alcohol consumption and smoking (PR = 0.78; 95% CI0.70 to 0.87).
