Policies call on after-school programs (ASPs) to serve more nutritious snacks. A major barrier for improving snack quality is cost. This study describes the impact on snack quality and expenditures from a community partnership between ASPs and local grocery stores.
Four large-scale ASPs (serving ˜500 children, aged 6-12 years, each day) and a single local grocery store chain participated in this study. The nutritional quality of snacks served was recorded preintervention (18 weeks spring/fall 2011) and postintervention (7 weeks spring 2012) via direct observation, along with cost/child/snack/day.
Preintervention snacks were low-nutrient-density salty snacks (eg, chips, 3.0 servings/week), sugar-sweetened beverages (eg, powdered-lemonade, 1.9 servings/week), and desserts (eg, cookies, 2.1 servings/week), with only 0.4 servings/week of fruits and no vegetables. By postintervention, fruits (3.5 servings/week) and vegetables (1.2 servings/week) were increased, whereas sugar-sweetened beverages and desserts were eliminated. Snack expenditures were $0.26 versus $0.24 from preintervention to postintervention. Partnership savings versus purchasing snacks at full retail cost was 24.5% or $0.25/serving versus $0.34/serving.
This innovative partnership can serve as a model in communities where ASPs seek to identify low-cost alternatives to providing nutritious snacks.
政策要求课后项目(ASP)提供更营养的零食。提高零食质量的一个主要障碍是成本。本研究描述了ASP与当地杂货店之间的社区合作对零食质量和支出的影响。
四个大型ASP(每天为约500名6至12岁儿童提供服务)和一家当地连锁杂货店参与了本研究。通过直接观察记录干预前(2011年春/秋季18周)和干预后(2012年春季7周)提供的零食的营养质量,以及每个孩子每天零食的成本。
干预前的零食是低营养密度的咸味零食(如薯片,每周3.0份)、含糖饮料(如柠檬水冲剂,每周1.9份)和甜点(如饼干,每周2.1份),每周只有0.4份水果,没有蔬菜。到干预后,水果(每周3.5份)和蔬菜(每周1.2份)增加了,而含糖饮料和甜点被消除了。零食支出从干预前的0.26美元降至干预后的0.24美元。与按全零售价购买零食相比,合作节省了24.5%,即每份0.25美元,而不是0.34美元。
这种创新的合作模式可以为那些ASP寻求低成本方式提供营养零食的社区提供一个范例。
