Official title: Multidimensional Intervention to Improve Healthy Lifestyle Practices and Nutrition and Health Status in Mexican Schoolchildren: Development of an Intervention Platform, Randomized Clinical Trial and Scaling Proposal
Run by Mexican National Institute of Public Health · NCT07185789 · Data updated 2026-11-12
This project will test whether a school-centered program that changes food, activity, and social surroundings can improve weight and health measures in 9–12-year-old students in three Mexican states.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are 9–12 year-old children in 4th grade who attend participating primary schools in Campeche, Mexico City, or Morelos during the morning or extended shifts (with specific school size requirements for Morelos).
✕Probably not a fit
Children who are not in 4th grade, who do not attend the selected schools or shifts, or who cannot participate in on-site school activities are unlikely to derive direct benefit.

What this trial studies
This is a randomized community trial delivering a multidimensional intervention across primary schools in Campeche, Mexico City, and Morelos targeting 4th-grade students (ages 9–12). The project includes a situational diagnosis, design and development of interventions, implementation, and evaluation phases carried out over multiple years. Interventions focus on healthy and sustainable eating, movement behaviors, and psychosocial determinants while measuring anthropometric, biological, psychological, behavioral, and environmental outcomes. Impact will be compared between intervention and control schools to see if changes in the school and surrounding environments translate to improved nutritional status and behaviors.
Why it matters
Potential benefit: If successful, students could adopt healthier eating and activity habits, show improved weight-related measures, and experience safer, more supportive school environments that reduce obesity risk.
How similar studies have gone: Previous school-based, multidimensional interventions have produced mixed but often modest positive effects on children's weight and health behaviors, so this approach has some supporting evidence.
