School-Based Cardiovascular Health Promotion in Adolescents
- Cluster randomised controlled trial
- 4-year
- 24 secondary schools
- Barcelona and Madrid, Spain
Authors' conclusion
Overall, the tested school-based health promotion strategies in this randomized clinical trial had a neutral effect on the CVH of the adolescents. Although there was evidence of a marginal beneficial effect at a point halfway through implementation in the LTI group, such a benefit was not noted at 4 years.
Study context
- Population
- Adolescents in the first grade of secondary school, Barcelona and Madrid, Spain, 2017–20211,326 enrolled
- Participants
- 412 / 504 / 441
- Comparison
- School-based health promotion (SI! Program) over 4 or 2 school years vs standard curriculum
- LTIn = 412
- STIn = 504
- Controln = 441reference
- Primary endpoint
- Between-group difference in change from baseline of overall cardiovascular health (CVH) score (AHA; 0-14 points, higher = healthier)
- Follow-up
- 2 and 4 years
