Availability and Quality of Healthy Foods Vary by Store Participation in SNAP and WIC in Low-Income California Neighborhoods

Between 2015–2017, California local health departments assessed the retail environment in a convenience sample of small markets and convenience stores in low-income neighborhoods. This study examined differences in availability and quality of healthy foods and the physical retail environment by retailer participation in SNAP and WIC and by store type. Among 731 stores, we found that SNAP + WIC stores offered the greatest availability of healthy foods, high-quality produce, and healthful exterior marketing. Select associations were stronger among convenience stores than for small markets. Policy levers to incentivize SNAP and WIC participation among retailers can improve the neighborhood food environment.
