Sommaire de l'article

OBJECTIVE
Great Taste, Less Waste (GTLW), a communications campaign, capitalized on the synergy between healthy eating and eco-friendly behaviors to motivate children to bring more fruits and vegetables and fewer sugar-sweetened beverages (SSBs) to school.

METHODS
A cluster-randomized trial in Eastern Massachusetts elementary schools in 2011-2012 tested the hypothesis that GTLW would improve the quality of foods from home more than a nutrition-only campaign-Foods 2 Choose (F2C)-or control. Lunch and snack items from home were measured at baseline and 7months later using digital photography. Mixed linear models compared change in mean servings of fruits, vegetables, and SSBs among groups, and change in mean prevalence of packaging type. Change in prevalence of food items of interest was compared among groups using generalized linear models.

RESULTS
Five hundred and eighty-two third and fourth graders from 82 classrooms in 12 schools participated. At follow-up, no significant differences were observed between groups in change in mean servings or change in prevalence of items of interest. No packaging differences were observed.

CONCLUSION
GTLW was well received, but no significant changes were observed in the quality of food brought to school. Whether classrooms are an effective environment for change remains to be explored. ClinicalTrials.gov identifier: NCT0157384.
