This paper examines the interactive effect between the price of unhealthy foods and Food Stamp Program participation on body weight status among low-income women in the United States. We merged the panel data of the National Longitudinal Survey of Youth 1979 cohort in 1985-2002 and the Cost of Living Index data compiled by the American Chamber of Commerce Researchers Association by using geographic identifiers. Using the merged data, we used panel econometric models to examine the impact of unhealthy food prices on the food stamp-eligible U.S. population. Our results indicate that higher prices for unhealthy food can partially offset the positive association between Food Stamp Program participation and bodyweight among low-income women.
本文研究了不健康食品价格与食品券计划参与情况对美国低收入女性体重状况的交互影响。我们利用地理标识符，将1985 - 2002年全国青年纵向调查1979年队列的面板数据与美国商会研究协会编制的生活成本指数数据进行了合并。利用合并后的数据，我们使用面板计量模型来研究不健康食品价格对符合食品券资格的美国人群的影响。我们的结果表明，不健康食品价格上涨可以部分抵消食品券计划参与与低收入女性体重之间的正相关关系。
