Perspective: Food Access at Dollar Stores and Its Implications for Public Health-Report of a Workshop on Identifying Research Priorities.

The rapid growth of dollar stores as retail sources of food in the United States is a phenomenon with implications for diets, nutrition, and well-being. We convened a broadly interdisciplinary group of researchers and experts from government and academia at the 2-day Food Access at Dollar Stores (FADS) workshop, held in Boston, MA in 2022. The event brought together economists, social scientists, public health researchers, and advocates to discuss the concerns and research questions raised by the growth of dollar stores and their increased role in food retail and access. In-person, moderated discussions on day 2 of the workshop generated a range of topics considered important for future research. A subsequent survey, using a modified Delphi approach, identified priority research areas. Nine research area categories emerged as a result of discussion at the FADS workshop and received prioritization from the experts: Local community impacts; Health and nutrition impacts; Policy and programs; Systemic issues - racism, poverty, and food access; Store offerings and locations; Shoppers and customers; Employees and employment; Corporate distribution, strategy, and marketing; and Dollar stores compared with other food sources. The growth of dollar stores as food retailers remains an under-researched area of study for food access and nutrition that requires interdisciplinary expertise and collaboration to understand.
