OBJECTIVE: Examine whether use of a grocery list is associated with healthier diet and weight among food desert residents. METHODS: Cross-sectional analysis of in-person interview data from randomly selected household food shoppers in 2 low-income, primarily African American urban neighborhoods in Pittsburgh, PA with limited access to healthy foods. RESULTS: Multivariate ordinary least-square regressions conducted among 1,372 participants and controlling for sociodemographic factors and other potential confounding variables indicated that although most of the sample (78%) was overweight or obese, consistently using a list was associated with lower body mass index (based on measured height and weight) (adjusted multivariant coefficient = 0.095) and higher dietary quality (based on the Healthy Eating Index–2005) (adjusted multivariant coefficient = 0.103) (P < .05). CONCLUSIONS AND IMPLICATIONS: Shopping with a list may be a useful tool for low-income individuals to improve diet or decrease body mass index.
