This article investigates the effect of fast-food availability on childhood weight outcomes by gender, race, and location. We use a novel identification strategy based on changes in fast-food exposure along the route between the home and school that occur as students progress through the public school system and transition to different types of schools, e.g. from elementary school to intermediate school or from intermediate school to high school. Using a longitudinal census of height and weight for public school students in Arkansas, we find no evidence that changes in fast-food exposure are associated with changes in body mass index -score for any student subpopulation.
本文按性别、种族和地点研究了快餐可得性对儿童体重结果的影响。我们采用了一种新颖的识别策略，该策略基于随着学生在公立学校系统中升学并转入不同类型学校（例如从小学升入初中或从初中升入高中），家庭与学校之间路线上快餐接触情况的变化。利用阿肯色州公立学校学生身高和体重的纵向普查数据，我们发现没有证据表明快餐接触情况的变化与任何学生亚群体的体重指数得分变化有关。
