Objective To determine whether there was an independent association between diet quality and household food insecurity using the Healthy Eating Index (HEI) and Dietary Reference Intakes (DRI), controlling for specific demographic variables in a high‐risk population. Design Random digit dialing telephone survey designed to collect data on food intake, household demographics, and food security status. Setting A representative sample of adults who live in 36 counties in the Lower Mississippi Delta (LMD) region of Arkansas, Louisiana, and Mississippi Participants 1607 adults, both white and black Main Outcome Measures Food security status and diet quality, including the HEI and DRI determinations from food intake reported (one day intake). Results Food secure (FS) adults scored higher on HEI than Food Insecure (FI) adults, but the regression model showed no differences when multiple factors were included. FS individuals consistently achieved higher percentages of the DRI than FI individuals, with the greatest differences seen for vitamin A, copper, and zinc and very little difference for vitamins C and E. Both populations consumed diets extremely low in fiber. Conclusions Food insecurity is associated with lower quality diets in this population. These findings point to a pressing need for nutrition interventions to improve dietary intake. Supported by USDA, ARS #6251‐53000‐004‐00D.
