Effect of Time-Varying Exposure to School-Based Health Promotion on Adiposity in Childhood
- Cluster randomised controlled trial
- 48 schools in Madrid (Spain)
Authors' conclusion
Early elementary school interventions may be more effective than later interventions on abdominal adiposity.
Study context
