Understanding Access to Grocery Stores in Food Deserts in Baltimore City
Disparities in access to healthy foods result in a food desert, which adversely affects health. A better understanding of the ways in which individuals access grocery store options is paramount in determining how to address these disparities. Using a food acquisition survey questionnaire, this study analyzes the travel patterns of 543 residents in Baltimore City. We applied Geographic Information System (GIS) approaches to determine the location of stores and homes of our participants in order to do an origin-destination analysis and determine driving and walking distance to the store. Also, we applied statistical analysis including logit regression, ANOVA, and descriptive analysis. Common knowledge dictates that car availability is critical to grocery access, and the study found that those who own a car visit more grocery store locations and shop more frequently. Those without vehicles either walk, take public transportation or take for-hire vehicles. Travel cost and location were significant predictors of choosing the nearest grocery store.
