Effectiveness of a health promotion program on overweight in vulnerable children from primary schools (BeE-school): A cluster-randomized controlled trial
Authors' conclusion
Conclusion: The school-based intervention, focusing on teacher training in health promotion and involving families, proved to be effective in improving body composition in socially vulnerable children.
