Area of Science:

• Nutrition Science

Background:

• Childhood nutrition is critical for long-term health and chronic disease prevention.
• School-based interventions are a key strategy for promoting healthy eating habits in children.
• Existing research on the effectiveness of these programs has varied findings.

Purpose of the Study:

• To assess the impact of school-based nutrition interventions on children's fruit and vegetable (FV) consumption.
• To conduct a pooled analysis of data from multiple studies to determine intervention effectiveness.
• To identify factors influencing FV intake in school settings.

Main Methods:

• A systematic search identified studies on school-based nutrition interventions published between 1990 and 2002.
• Data from 7 eligible studies, involving 8156 children, were pooled for analysis.
• Individual- and study-level analyses were performed using multivariable fixed-effects models.

Main Results:

• School-based nutrition interventions led to a significant increase in FV consumption.
• On average, children consumed an additional 0.45 servings of FV (net difference).
• This represented a 19% relative increase in FV intake.

Conclusions:

• School-based nutrition interventions are effective in moderately increasing children's FV intake.
• These findings have significant implications for public health initiatives aimed at chronic disease prevention, including cardiovascular disease and cancer.
• Implementing and supporting these programs can contribute to healthier childhood diets and reduced disease risk.
