Results showed that the various school-based lifestyle interventions were not associated with a statistically significant overall effect on BMI-for-age compared with control groups (MD = 0.03, 95% CI: −0.24 to 0.29; p = 0.813).
Contexto
What changed: Schools implemented lifestyle interventions combining physical activity, nutrition education, or dietary supplementation lasting 9 weeks to 1 year. Comparison: Control groups received usual schooling or standard basic care. Limits: High heterogeneity across studies, predominantly quasi-experimental designs, and geographic concentration in South Africa.
