SUMMARY:

Introduction: Common mental disorders (CMDs) are characterized by symptoms of anxiety, depression, and somatic complaints. The prevalence of CMDs is increasing, particularly among young people, and has a significant impact on health. Physical activity has been associated with a reduction in CMDs, while excessive screen time has been linked to worsening symptoms of depression and anxiety. Objective: To analyze the joint association between physical activity and screen time with the occurrence of common mental disorders in Brazilian adolescents aged 12 to 17 years, considering a dose-response gradient. Methods: This study utilized data from the Study of Cardiovascular Risk in Adolescents (ERICA), a multicenter cross-sectional study conducted between 2013 and 2014. The sample included adolescents from public and private schools in Brazilian municipalities with populations over 100,000. Physical activity was assessed through a validated questionnaire on moderate-to-vigorous physical activity (MVPA). Screen time was quantified using a questionnaire that evaluated daily hours spent using computers, watching TV, and playing video games during a typical week. CMDs were assessed using the 12-item General Health Questionnaire (GHQ-12). Sociodemographic and economic covariates were also considered. Poisson regression models with robust variance stratified by sex were used to analyze the associations. Results: A total of 65,048 adolescents with a mean age of 14.7 years were evaluated. The prevalence of CMDs was 16.9%, higher among girls. Excessive screen time (≥6 hours/day) was positively associated with CMDs in adjusted analyses for both girls (PR: 1.60; 95% CI: 1.44-1.79) and boys (PR: 1.40; 95% CI: 1.15-1.72). Regarding physical activity, a U-shaped association was observed with CMDs, showing greater protection among boys. In the joint analysis of physical activity and screen time with CMDs, no physical activity (0 min/day) combined with excessive screen time (≥6 hours/day) resulted in prevalence ratios 46% and 72% higher in girls and boys, respectively. Stratified analyses showed no attenuation in the association between screen time and CMDs based on the adolescents' physical activity levels. Conclusion: This study observed that engaging in physical activity and limiting screen time are associated with a lower prevalence of CMDs in Brazilian adolescents. Public policies aimed at promoting healthy movement behaviors could positively impact the mental health of adolescents.
