关于课后环境中的营养环境如何影响儿童的饮食摄入量，人们知之甚少。我们测量了参与国家学校午餐计划或儿童和成人护理食品计划的项目提供的课后零食的营养质量，并将其与从家里带来或在其他地方购买的零食（非计划零食）进行了比较。我们量化了非计划零食对那些在放学后也接受计划提供零食的儿童饮食摄入量的影响。我们的研究目的是确定不同来源的零食如何影响儿童在放学后的零食消费。2011年4月和5月，我们在马萨诸塞州波士顿的18个课后项目中记录了298名儿童在5个项目日提供和带来的零食。我们使用经过验证的观察方案测量了2个项目日儿童的零食消费量。然后，我们计算了儿童内变化模型，以估计非计划零食对儿童放学后饮食摄入的影响。非计划零食比计划提供的零食含有更多的含糖饮料和糖果。在零食期间，吃非计划性零食与总热量（+114.7千卡，P < .001）、含糖饮料（+0.5盎司，P = .01）、甜点（+0.3份，P < .001）和添加糖的食物（+0.5份; P < .001）的消耗量显著增加相关。在孩子们自带课后零食的日子里，他们摄入的咸味和糖分食物更多，摄入的卡路里几乎是只吃项目提供的零食的日子的两倍。应进一步探讨限制非计划零食或为他们在课后设置营养标准的政策策略，作为促进儿童健康的一种方式。
Little is known about how the nutrition environment in after-school settings may affect children’s dietary intake. We measured the nutritional quality of after-school snacks provided by programs participating in the National School Lunch Program or the Child and Adult Care Food Program and compared them with snacks brought from home or purchased elsewhere (nonprogram snacks). We quantified the effect of nonprogram snacks on the dietary intake of children who also received program-provided snacks during after-school time. Our study objective was to determine how different sources of snacks affect children’s snack consumption in after-school settings. We recorded snacks served to and brought in by 298 children in 18 after-school programs in Boston, Massachusetts, on 5 program days in April and May 2011. We measured children’s snack consumption on 2 program days using a validated observation protocol. We then calculated within-child change-in-change models to estimate the effect of nonprogram snacks on children’s dietary intake after school. Nonprogram snacks contained more sugary beverages and candy than program-provided snacks. Having a nonprogram snack was associated with significantly higher consumption of total calories (+114.7 kcal, P < .001), sugar-sweetened beverages (+0.5 oz, P = .01), desserts (+0.3 servings, P < .001), and foods with added sugars (+0.5 servings; P < .001) during the snack period. On days when children brought their own after-school snack, they consumed more salty and sugary foods and nearly twice as many calories than on days when they consumed only program-provided snacks. Policy strategies limiting nonprogram snacks or setting nutritional standards for them in after-school settings should be explored further as a way to promote child health.
