补充营养援助计划 (SNAP)、免费和降价午餐计划 (FRPL) 以及针对妇女、婴儿和儿童的特殊补充营养计划 (WIC) 减少了数百万低收入美国人的粮食不安全状况。然而，这些计划的批评者质疑它们是否会增加肥胖。这项研究调查了参加每个项目是否与从幼儿园到五年级的儿童体重指数 z 分数 (BMIz) 相关。作为早期儿童纵向研究 (ECLS-K:2011) 的一部分，我们对 4,457 名从幼儿园到五年级家庭收入等于或低于联邦贫困线 200% 的小学生的数据进行了分析。使用具有治疗/审查权重逆概率的边际结构模型来估计家长报告的 SNAP/FRPL 参与随时间变化与五年级 BMIz 之间的关联，并解释失访和随时间变化的混杂因素。使用加权广义估计方程来检验 WIC 参与与 BMIz 趋势之间的关联。所有分析均纳入 ECLS-K 采样权重。 ECLS-K:2011 数据收集于 2010 年至 2016 年，并于 2021 年和 2022 年进行分析。在基线时，该样本中有 2,419 名 (54.3%) ECLS-K 参与者使用 SNAP，3,993 名 (89.6%) 参与了 FRPL，3,755 名 (84.2%) 报告了过去参与过 WIC。没有发现任何计划与五年级结束时的 BMIz 之间或 WIC 参与与 BMIz 趋势之间存在关联。先前关于计划参与与体重指数之间关系的发现可能是由于较弱的研究设计和不受控制的混杂因素造成的。在最近进行的这项纵向研究中，SNAP、FRPL 和 WIC 与儿童肥胖风险增加无关。
The Supplemental Nutrition Assistance Program (SNAP), Free and Reduced Priced Lunch program (FRPL), and Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) reduce food insecurity for millions of Americans with lower incomes. However, critics of the programs have questioned whether they increase obesity. This study examined whether participating in each program was associated with child BMI z-score (BMIz) from kindergarten to fifth grade. Data from 4,457 primary grade students whose household incomes were equal to or below 200% of the federal poverty level from kindergarten to fifth grade as part of the Early Childhood Longitudinal Study (ECLS-K:2011) were analyzed. Marginal structural models with inverse probability of treatment/censoring weights were used to estimate the association between parent-reported SNAP/FRPL participation over time and fifth grade BMIz, accounting for loss-to-follow-up and time-varying confounders. Weighted generalized estimating equations were used to examine the association between WIC participation and BMIz trends. All analyses incorporated ECLS-K sampling weights. ECLS-K:2011 data were collected from 2010 to 2016, and analyses were conducted in 2021 and 2022. At baseline, 2,419 (54.3%) ECLS-K participants in this sample used SNAP, 3,993 (89.6%) participated in FRPL, and 3,755 (84.2%) reported past WIC participation. No associations were found between any program and BMIz at the end of fifth grade or between WIC participation and BMIz trend. Prior findings of a relationship between program participation and BMI may have been due to weaker study designs and uncontrolled confounding. SNAP, FRPL, and WIC were not associated with increased risk of childhood obesity in this recently conducted longitudinal study.
