Unequal access to healthy food environments is often implicated in racial inequities in health and behaviors that are largest among college graduates. The aim of this study was to determine associations between perceived proximity to food sources and dietary behaviors between black and white college graduates.
In a cross-sectional online survey of dietary behaviors between black and white adults who have a ≥ 4-year bachelor's degree, respondents were asked how long it typically takes for them to get to grocery stores and fast-food restaurants from home. We used ordinal logit regression models to assess associations between perceived proximity to food sources and dietary behaviors.
Among black men, perceiving that a grocery store was ≥ 10 minutes from their home was associated with lower fruit consumption (beta=-0.94, SE=0.48). Perceiving that a grocery store was ≥ 10 minutes from their home was associated with more frequent fast-food consumption among black men (beta=1.21, SE=0.39), Black women (beta=0.98, SE=0.34), and white men (beta=0.74, SE=0.30).
The associations between perceived proximity to food sources and dietary behaviors differ by race and sex among college graduates with important implications for racial disparities in diet quality and obesity across SES.
健康食品环境获取机会不均等，往往与健康方面的种族不平等以及大学毕业生中最大的行为有关。本研究旨在确定黑人和白人大学毕业生之间感知食物来源的接近程度与饮食行为之间的关联。
在一项针对具有≥4 年学士学位的黑人和白人成年人饮食行为的横断面在线调查中，要求受访者回答他们通常从家到杂货店和快餐店需要多长时间。我们使用有序逻辑回归模型来评估感知食物来源的接近程度与饮食行为之间的关联。
在黑人男性中，认为杂货店离家≥10 分钟与水果摄入量较低有关（β=-0.94，SE=0.48）。认为杂货店离家≥10 分钟与黑人男性（β=1.21，SE=0.39）、黑人女性（β=0.98，SE=0.34）和白人男性（β=0.74，SE=0.30）食用快餐的频率更高有关。
感知食物来源的接近程度与饮食行为之间的关联因种族和性别而异，这对 SES 层面上饮食质量和肥胖的种族差异具有重要意义。
