Background: The Supplemental Nutrition Assistance Program Education (SNAP-Ed) is the federal nutrition education program of the United States Department of Agriculture Food and Nutrition Service (USDA-FNS) Supplemental Nutrition Assistance Program (SNAP). SNAP-Ed is designed to increase the likelihood that individuals with limited budgets can eat a healthy diet and achieve a physically active lifestyle based on the 2020-2025 Dietary Guidelines for Americans (DGA) (U.S. Department of Health and Human Services & U.S. Department of Agriculture, 2020) and public health approaches. The Food and Nutrition Service (FNS) Southeast Region SNAP-Ed program includes eight states with 25 implementing agencies (IAs) and their partners. This evaluation of the Southeast Region SNAP-Ed program assessed: (1) SNAP-Ed Policy, Systems and Environmental (PSE) changes implemented throughout the Southeast Region, including medium-term and long-term changes (MT5/MT6 and LT5/LT6); and (2) The COVID-19 response in implementing SNAP-Ed programming in the Southeast Region (SER). Methods: Medium-term and long-term PSE changes were reported by the SER IAs using a Microsoft Excel template or through a data export from the Program Evaluation and Reporting System (PEARS). Descriptive analyses were conducted to calculate the number of PSE changes and the reach of those changes. IAs reported how they have adapted to the COVID-19 pandemic via a SurveyMonkey questionnaire. Descriptive analyses of this data were also conducted. Results: IAs reported a total of 1,359 PSE changes across 7 states with a combined reach of 1,161,289. Of those changes, there were 108 (7.9%) policy changes, 602 (44.3%) systems changes, and 649 (47.8%) environmental changes. For long-term PSE changes, a total of 666 sites (91%) reported a multi-component intervention with their PSE nutrition change and a total of 194 sites (97%) reported a multi-component intervention with their PSE physical activity change. Also, all IAs reported adaptations to their SNAP-Ed programming based on COVID, which included partnering with 12,188 new or existing partners to implement direct education, PSE changes, and social marketing programs and moving direct and indirect education materials online. Conclusion: In 2020, states and IAs were able to quickly pivot to meet the needs of their communities during the COVID-19 pandemic, reaching more than 1.1 million people with PSE changes. Adaptations that proved successful included the development of digital resources, moving education classes online and maintaining and expanding partnerships.
