The lack of access to affordable and healthy food is cited as a significant reason for health disparities in society and threatens public health. For decades, trends in the urbanization and food retail sector have left a considerable part of the society deprived of affordable and healthy food outlets in their neighborhoods. This is especially the case for low-income groups and people of color. In addition to the uneven spatial distribution of healthy and affordable food outlets, defining food access in itself is a very complex task. This complexity makes developing strategies to solve food access issues in society challenging. People's or households' decisions regarding where to shop, how far to travel, and what to purchase, as well as different individual and household attributes, ranging from where they live to how much they value diet, are all important. Hence, the following dissertation aims to examine the different characteristics that impact where households shop, how far they travel, and what they purchase. The goal is to broaden our understanding of food access.
The dissertation includes three different studies using information from the USDA's National Household Food Acquisition and Purchase Survey (FoodAPS) dataset. Specifically, the first study addresses food store choice of shoppers, including their ability to access the nearest healthy store (supermarket/superstore), unhealthy stores (gas station, convenience store, dollar store), and other healthy stores (specialty stores, farmers' markets, medium to large grocery stores). The first study highlights how price and distance matter for selecting the nearest healthy store. When the nearest healthy store is a far distance, shoppers are driven to purchase at nearby stores, which may be unhealthy or small healthy stores, such as a grocery store. The second study examines factors that affect the distances household travel for food. The surrounding food environment is associated with total real traveled miles (open full item for complete abstract)
