• Description:
  Background ; Afterschool interventions have been found to improve the nutritional quality of snacks served. However, there is limited evidence on how these interventions affect children’s snacking behaviors. ; Objective ; To determine the impact of an afterschool intervention focused at the school district, site, family, and child levels on dietary consumption of foods and beverages served at snack. ; Design ; Secondary analysis of a group-randomized controlled trial. ; Participants/setting ; Data were collected from 400 children at 20 Boston, MA afterschool sites before (fall 2010) and after (spring 2011) intervention implementation. ; Intervention ; The Out-of-School Nutrition and Physical Activity intervention aimed to promote fruits, vegetables, whole grains, and water, while limiting sugary drinks and trans fats. Researchers worked with district foodservice staff to change snack foods and beverages. Teams of afterschool staff participated in three three-hour learning collaborative sessions to build skills and created action plans for changing site practices. The intervention included family and child nutrition education. ; Main outcome measures ; Research assistants observed dietary snack consumption using a validated measure on two days per site at baseline and follow-up. ; Statistical Analyses Performed ; This study used multivariable regression models, accounting for clustering of observations, to assess the intervention effect, and conducted post-hoc stratified analyses by foodservice type. ; Results ; Children in intervention sites had greater decreases in consumption of juice (−0.61 ounces/snack, 95% CI −1.11 – −0.12), beverage calories (−29.0 kcal/snack, 95% CI −40.1 – −17.9), foods with trans fats (−0.12 servings/snack, 95% CI −0.19 – −0.04), total calories (−47.8 kcal/snack, 95% CI −68.3 – −27.3) and increases in consumption of whole grains (0.10 servings/snack, 95% CI 0.02–0.18) compared to controls. In post hoc analyses, sites with on-site foodservice had significant improvements for all outcomes (p<0.001), with no effect for sites with satellite foodservice. ; Conclusions ; Results demonstrate that an afterschool intervention can improve children’s dietary snack consumption, particularly at sites with on-site foodservice.
