Influence of the supply network on the availability of healthy foods in small food stores of urban, low‐income settings (384.4)

Abstract

Disparities in healthy food access commonly exist in urban low‐income neighborhoods, where small food stores predominate. What is not commonly understood is the supply network of these small food stores, and how this influences the food they stock. We conducted a network analysis to assess the influence of the supply network of corner stores on food procurement patterns and stocking of essential foods (fresh produce) versus non‐essential foods (snacks and beverages). We surveyed a sample of corner stores (n=24) in low‐income neighborhoods of Baltimore City, their suppliers (wholesalers, warehouse clubs, supermarkets, superstores) and their delivery vendors that provide shipments from manufacturers. Preliminary findings showed that, on average, each corner store is connected to more delivery vendors (6) than suppliers (3), resulting in a greater supply of non‐essential foods. Furthermore, non‐essential food procurement was more likely in corner stores with greater numbers and types of delivery vendors. With few alternatives, corner stores also show more reliance on a limited number of wholesalers in procuring essential foods. Our study highlights the significance in analyzing the supply network structure to identify potential points of intervention. To improve the availability of essential foods in small food stores, efforts are needed to increase diversity and density in a corner store’s supply network.
