本文探讨了长期食品券计划（FSP）的参与和超重的儿童使用的数据从全国青年纵向调查1979年儿童样本的儿童之间的关系。如果一个孩子的BMI大于或等于性别和年龄特定BMI的第95百分位数，他或她就被归类为超重。这些数据被安排为一个小组，每个孩子有多个观察结果，超重的首选模型包括长期FSP参与，其他人口统计学，社会经济学和环境特征，以及儿童固定效应。儿童固定效应用于考虑儿童之间未观察到的差异，这些差异不随时间变化。模型分别针对年龄较小（5-11岁）和年龄较大（12-18岁）的儿童进行估计。在普通最小二乘模型中，长期FSP参与与年轻女孩的超重呈正相关（P = 0.048），与年轻男孩的超重呈负相关（P = 0.100）。与家庭在过去5年中没有参加FSP的女孩和男孩相比，在过去5年中参加FSP的女孩和男孩的预测超重概率分别增加了42.8%和28.8%。长期FSP参与与年龄较大儿童的超重没有显着相关。虽然这些模型没有控制粮食不安全，粮食不安全的潜在作用，在FSP参与和儿童体重之间的关系的解释被认为是FSP参与。
This paper examines the relation between long-term Food Stamp Program (FSP) participation and overweight in children using data on children from the National Longitudinal Survey of Youth 1979 Child Sample. A child was categorized as overweight if his or her BMI was greater than or equal to the 95th percentile of sex- and age-specific BMI. The data were arranged as a panel with multiple observations per child, and the preferred models of overweight included long-term FSP participation, additional demographic, socioeconomic, and environmental characteristics, and child fixed effects. Child fixed effects were used to take into account unobserved differences across children that did not vary over time. The models were estimated separately for younger (5-11 y old) and older (12-18 y old) children. In Ordinary Least Squares models, long-term FSP participation was positively and significantly related to overweight in young girls (P = 0.048), and negatively and significantly related to overweight in young boys (P = 0.100). Compared with girls and boys whose families did not participate in the FSP during the previous 5 y, FSP participation during all of the previous 5 y was associated with a 42.8% increase for young girls and a 28.8% decrease for young boys in the predicted probability of overweight. Long-term FSP participation was not significantly related to overweight in older children. Although these models did not control for food insecurity, the potential role of food insecurity in FSP participation was considered in the interpretation of the relation between FSP participation and child weight.
