The purpose of this research was to examine whether the local food environment, specifically the distance to the nearest sugar sweetened beverage (SSB) vendor, a measure of SSB availability and accessibility, was correlated with the likelihood of self-reported SSB consumption among a sample of fast food consumers. As part of a broader SSB behavior study in 2013-2014, respondents were surveyed outside of major chain fast food restaurants in New York City (NYC). Respondents were asked for the intersection closest to their home and how frequently they consume SSBs. Comprehensive, administrative food outlet databases were used to geo-locate the SSB vendor closest to the respondents' home intersections. We then used a logistic regression model to estimate the association between the distance to the nearest SSB vendor (overall and by type) and the likelihood of daily SSB consumption. Our results show that proximity to the nearest SSB vendor was not statistically significantly associated with the likelihood of daily SSB consumption, regardless of type of vendor. Our results are robust to alternative model specifications, including replacing the linear minimum distance measure with count of the total number of SSB vendors or presence of a SSB vendor within a buffer around respondents' home intersections. We conclude that there is not a strong relationship between proximity to nearest SSB vendor, or proximity to a specific type of SSB vendor, and frequency of self-reported SSB consumption among fast food consumers in NYC. This suggests that policymakers focus on alternative strategies to curtail SSB consumption, such as improving the within-store food environment or taxing SSBs.
本研究旨在探讨局部食品环境(特别是距离最近的含糖饮料(SSB)供应商的距离,这是 SSB 供应和可及性的衡量标准)是否与快餐消费者中自我报告的 SSB 消费可能性相关。作为 2013-2014 年 SSB 行为研究的一部分,受访者在纽约市(NYC)的主要连锁快餐店外接受调查。受访者被问及离家最近的十字路口以及他们经常消费 SSB 的频率。综合行政食品店数据库用于确定受访者家十字路口附近最近的 SSB 供应商的地理位置。然后,我们使用逻辑回归模型来估计距离最近的 SSB 供应商(总体和按类型)与每日 SSB 消费可能性之间的关联。我们的研究结果表明,无论供应商类型如何,与最近的 SSB 供应商的距离与每日 SSB 消费的可能性均无统计学显著关联。我们的结果在替代模型规范下是稳健的,包括用 SSB 供应商总数的计数或受访者家十字路口周围缓冲区中 SSB 供应商的存在替代线性最小距离度量。我们得出的结论是,在纽约市快餐消费者中,最近的 SSB 供应商的距离或特定类型的 SSB 供应商的距离与自我报告的 SSB 消费频率之间没有很强的关系。这表明政策制定者应关注其他策略来限制 SSB 的消费,例如改善店内食品环境或对 SSB 征税。
