The effects of physical activity on the mental health of typically developing children and adolescents: a systematic review and meta-analysis
Abstract
Physical activity has gained attention in recent years as a promising intervention for improving the mental health of children and adolescents. However, evidence supporting the effectiveness of physical activity interventions for the mental health of typically developing children and adolescents remains limited. This study conducted a comprehensive search across five electronic databases up to July 2024. Studies were eligible for inclusion if they involved an intervention with a control group that examined the effects of physical activity on the mental health of typically developing children and adolescents. Articles focusing on participants with developmental, behavioral, or psychiatric disorders were excluded. A random-effects meta-analysis was conducted using Stata 18.0. The quality of evidence and risk of bias were assessed using the GRADE framework and the PEDro scale. The initial search yielded 27,527 articles, of which 30 met the inclusion criteria. Meta-regression analysis indicated that country and intervention frequency were significant sources of heterogeneity. Physical activity interventions were significantly more effective than the control group in improving mental health (SMD = 0.37, 95% CI: 0.20 to 0.53). These interventions showed particularly strong effects on stress reduction (SMD = 0.86, 95% CI: 0.15 to 1.56) and social competence enhancement (SMD = 0.56, 95% CI: 0.07 to 1.06). Moreover, physical activity interventions were notably more effective for male…
