This paper evaluates the effectiveness of restrictions on sugar-sweetened beverages (SSBs) in schools as a policy approach aimed at reversing the upward trend in obesity among adolescents. Specifically, we test if the implementation of SB 965 in California high schools led to detectable compensation effects outside of school by estimating changes in soda purchases observed in store-level scanner data. Our unique data and identification strategy address data limitations of previously published studies, and our reported results strengthen the notion that preferences for unhealthy foods will persist even after their availability is restricted in select environments.

加州高中对含糖饮料的国家规定限制是否增加了学校社区的苏打水购买量？

本文评估了在学校限制含糖饮料 (SSB) 作为旨在扭转青少年肥胖上升趋势的政策方法的有效性。具体来说，我们通过估计在商店级扫描仪数据中观察到的苏打水购买变化来测试加州高中实施 SB 965 是否会导致可检测到的校外补偿效应。我们独特的数据和识别策略解决了先前发表的研究的数据限制，我们报告的结果强化了这样一种观念，即即使在某些环境中限制了不健康食品的供应后，对不健康食品的偏好也会持续存在。
