Household disability status, food store choice, and food insecurity in the United States.

Disability is a known risk factor for food insecurity, even when accounting for household income. However, the mechanisms driving the relationship between disability and food insecurity remain underexplored. Using the National Household Food Acquisition and Purchase Survey, I test the extent to which food store choice (representing food access) mediates the association between disability and food insecurity in the United States. The analysis is complicated by the notion that food insecurity also influences food store choice. Nevertheless, multivariate regression findings suggest that food access is not a significant driver of high rates of food insecurity among households where disabilities are present.
