Sustaining Heart-Healthy Habits in Youth: A 15-Year Review of the SI! Program
摘要
This review examines the effectiveness of school-based interventions for preventing cardiovascular disease and promoting healthy lifestyles, drawing on evidence from the SI! Program. It addresses two key questions: how such interventions influence health behaviors throughout childhood and adolescence, and which contextual factors shape their effectiveness and sustainability.
Recent FindingsEvidence from multiple randomized controlled trials conducted over 15 years in diverse school settings shows that multicomponent, multilevel interventions can positively shape cardiovascular health behaviors. Studies involving more than 7,000 students in Colombia, Spain, and the United States highlight adherence and socioeconomic background as key determinants of impact.
SummaryIntervention effects are strongly influenced by educational stage, adherence, and the school and home environment. Periodic reinterventions appear necessary to sustain benefits over time. Baseline health status and intervention responsiveness are also conditioned by socioeconomic context. Scaling and supporting such programs may foster lasting healthy habits early in life and help reduce global cardiovascular disease burden.
