    While many randomized controlled trials (RCTs) have demonstrated the positive effects of school-based programs in reducing body fat among children and teenagers, there is no conclusive evidence to indicate that one approach is superior to another, largely due to the lack of direct and indirect comparisons. This study evaluated the relative effectiveness of various school-based obesity prevention initiatives in improving body mass index (BMI) among children and adolescents through the use of network meta-analysis. Searches included 4 databases focusing on articles published in English between the years 2002 and 2024. The primary outcomes were BMI and BMI z-score (BMIz) (kg/m2). The mean differences (MDs) for each outcome were calculated before and after treatment. The current systematic review synthesized 53 RCTs with a sample of 68,489 children and adolescents. Results illustrated that physical activity (PA) only arm was the most effective intervention in improving BMI (MD: -0.42, 95% credible interval (Crl) -0.79, -0.07; p=0.02). While multiple components arm was the most effective intervention in improving BMIz (MD: -0.08, 95% Crl: -0.16, -0.01; p=0.03). Inversely, PA & another component arm was the least effective intervention in improving BMI (MD: 0.64, 95% Crl: -0.23, 1.53; p=0.15), in addition, diet & nutrition only arm was the least effective intervention in improving BMIz (MD: 0.09, 95% Crl: -0.11, 0.28; p=0.36). In conclusion, PA only and multiple components arms are effective intervention tools/strategies for reducing BMI-related outcomes, nevertheless, large well-designed studies to investigate the elements of multiple components arms warrants further justification.
