The review was not prospectively registered. Eligible records examined at least one socioecological correlate in relation to physical activity, flourishing, wellbeing, depression, or depressive symptoms. Data were extracted using a standardized form, and methodological quality was appraised using design-appropriate tools, including AMSTAR-2 for systematic reviews and meta-analyses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Thirty-six evidence records were retained. Self-efficacy, enjoyment, perceived competence, parental logistic support, family cohesion, peer support, quality physical education, school sport opportunities, recreation-facility access, walkability, perceived safety, and national physical-activity policy emerged as recurrent correlates across socioecological levels. The evidence was most concentrated at intrapersonal and interpersonal levels and comparatively less developed for community and policy-level correlates. Evidence from prior meta-analyses suggested small-to-moderate beneficial associations of physical-activity interventions with depressive symptoms and broader mental-health outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Youth physical activity, flourishing, and depression are associated with correlates distributed across multiple socioecological levels. Coordinated school, family, community, and policy strategies are needed to promote equitable physical-activity participation and positive mental health, while causal claims should be interpreted cautiously because much of the evidence remains observational.<\/jats:p>\n
