Impact of Grocery Store Proximity on Store Preference Among Atlanta SNAP-Ed Participants

To assess the association between grocery store proximities and the individual's grocery store preferences among Supplemental Nutrition Assistance Program Education participants in Atlanta.

University of Georgia Supplemental Nutrition Assistance Program Education participants (n = 615, response rate is 36%) in 3 counties provided their preferred grocery store chains. The association between store proximity (both network distance and driving time) and store preference was measured through logistic regression controlling for age, sex, and race.

Descriptive statistics showed participants had widely varying proximities to grocery stores. Model results were significant for all smaller chains (Aldi, Big Bear, Wayfield, Food Depot, and Save-A-Lot), Kroger (P < 0.01), as well as for Walmart (time only, P = 0.002).

Future studies might identify whether local groceries are more willing to partner on interventions or are more effective at reaching local residents. Surveys or techniques such as sketch mapping could also show whether individuals shop in neighborhoods close to work or friends and family.
