BACKGROUND: Understanding the impact of environmental factors on physical activity (PA) and physical fitness (PF) is crucial for promoting a healthy lifestyle among children and adolescents. This study examines how awareness of sports policies, school, family, and community environments influence PA and PF in Chinese youth. METHODS: A cross-sectional study was conducted with 2747 children and adolescents (mean age 12.90 ± 2.49; 48.2% male) from 17 schools across five Chinese cities. Environmental factors were assessed via questionnaires, and PA levels were measured using the International Physical Activity Questionnaire-Short Form (IPAQ-SF). PF metrics, including BMI, waist-to-height ratio, grip strength, vertical jump, and 20-m shuttle run test (20-mSRT), were measured onsite. Structural Equation Modeling (SEM) was used to explore relationships between environmental factors and PA/PF outcomes. RESULTS: The school environment scored highest (78.0 ± 9.5), while the community environment scored lowest (38.7 ± 18.0). Family environment positively influenced low-intensity PA (LPA) (β = 0.102, P < 0.001) but negatively affected moderate-to-vigorous PA (MVPA) (β = -0.055, P = 0.035). Community environment and awareness of sports policies positively impacted MVPA (β = 0.216, P < 0.001; β = 0.072, P = 0.009, respectively). Family environment positively influenced BMI reduction (β = -0.103, P < 0.001) but negatively affected grip strength (β = -0.063, P = 0.018). Community environment...
