Sixteen percent of children 6-11 years of age were classified as overweight in 1999-2002, four times the percentage in 1965. Although poverty has traditionally been associated with underweight as a result of poor diet, researchers have recently pointed to a paradox in the U.S., which is that low income and obesity can coexist in the same population. This paper first examines whether income is linked to overweight in school-age children. Second, it explores whether food programs such as the Food Stamp Program, the National School Lunch Program, and the School Breakfast Program are associated with overweight among children in different income groups. The data come from the nationally representative 1997 Panel Study of Income Dynamics Child Development Supplement. No evidence either that poor children are more likely to be overweight or that food programs contribute to overweight among poor children was found.
1999年至2002年期间，16%的6至11岁儿童被归类为超重，这一比例是1965年的四倍。传统上，由于饮食不良，贫困一直与体重不足相关，但研究人员最近指出美国存在一个悖论，即低收入和肥胖可能在同一人群中并存。本文首先研究收入是否与学龄儿童超重有关。其次，探讨食品券计划、国家学校午餐计划和学校早餐计划等食品项目是否与不同收入群体儿童的超重有关。数据来自具有全国代表性的1997年收入动态面板研究儿童发展补充调查。没有发现证据表明贫困儿童更有可能超重，也没有发现食品项目导致贫困儿童超重。
