Association between Proximity to Food Sources and Dietary Behaviors in Black and White College Graduates

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.
