Sommaire de l'article

This group-randomized controlled trial examines the effects of a school garden intervention on availability of fruits and vegetables (FV) in elementary school children's homes. Within each region, low income U.S. schools in Arkansas, Iowa, New York, and Washington State were randomly assigned to intervention group (n = 24) or waitlist control group (n = 22). Children were in grades 2, 4, and 5 at baseline (n = 2768). The garden intervention consisted of both raised-bed garden kits and a series of grade-appropriate lessons. FV availability at home was measured with a modified version of the GEMS FJV Availability Questionnaire. The instrument was administered at baseline (Fall 2011) and throughout the intervention (Spring 2012, Fall 2012, Spring 2013). Analyses were completed using general linear mixed models. The garden intervention led to an overall increase in availability of low-fat vegetables at home. Among younger children (2nd grade at baseline), the garden intervention led to greater home availability of vegetables, especially, low-fat vegetables. Moreover, for the younger group, garden intervention fidelity (GIF) or robustness predicted home availability of fruit, vegetables, and low-fat vegetables. School gardens have potential to affect FV availability in the home environment.
