Sommaire de l'article

Purpose . The aim of this study was to evaluate an intervention designed to assist after-school programs (ASPs) in meeting snack nutrition policies that specify that a fruit or vegetable be served daily and sugar-sweetened beverages/foods and artificially flavored foods eliminated.

Design . The study used a 1-year group-randomized controlled trial. Setting . The study took place in ASPs operating in South Carolina, United States.

Subjects . Twenty ASPs serving over 1700 children were recruited, match-paired postbaseline on enrollment size and days fruits/vegetables were served per week, and randomized to either intervention (n = 10) or control (n = 10) groups. Intervention . The study used Strategies To Enhance Practice for Healthy Eating (STEPs-HE), a multistep adaptive intervention framework that assists ASP leaders and staff to serve snacks that meet nutrition policies while maintaining cost.

Measures . Direct observation of snacks served and consumed and monthly snack expenditures as determined by receipts were used.

Analysis . The study used nonparametric and mixed-model repeated measures.

Results . By postassessment, intervention ASPs increased serving of fruits/vegetables to 3.9 ± 2.1 vs. 0.7 ± 1.7 d/wk and decreased serving sugar-sweetened beverages to 0.1 ± 0.7 vs. 1.8 ± 2.4 d/wk and sugar-sweetened foods to 0.3 ± 1.1 vs. 2.7 ± 2.5 d/wk compared to controls, respectively. Cost of snacks increased by $0.02/snack in the intervention ASPs ($0.36 to $0.38) compared to a $0.01 per snack decrease in the control group ($0.39 to $0.38). Across both assessments and groups, 80% to 100% of children consumed FVs.

Conclusions . The STEPs-HE intervention can assist ASPs in meeting nationally endorsed nutrition policies with marginal increases in cost.
