Abstract
Objective
To evaluate, through study- and individual-level analyses of data from 7 studies,
the effectiveness of school-based nutrition interventions on child fruit and vegetable
(FV) consumption.
Design
To find original studies on school-based nutrition interventions, the authors searched
electronic databases from 1990 to 2002. First authors of the 13 eligible studies were
contacted to request their data. Data from 7 studies were received for inclusion in
this pooled analysis.
Setting
Schools.
Participants
8156 children were matched from pretest to posttest. Participants were primarily elementary
school-aged (75.5%) and white (66%), and 50.4% were males.
Main Outcome Measures
Net FV difference and net FV relative change (%).
Analysis
Data were analyzed at both the study and individual levels. A fitted multivariable
fixed-effects model was used to analyze the role of potential covariates on FV intake.
Statistical significance was set at α = .05.
Results
At the individual level, the net difference in FV consumption was 0.45 (95% CI 0.33-0.59)
servings; the net relative change was 19% (95% CI 0.15-0.23) servings.
Conclusions and Implications
School-based nutrition interventions produced a moderate increase in FV intake among
children. These results may have implications for chronic disease prevention efforts,
including cardiovascular disease and cancer.
