The Mountain Plains Region (Colorado, Iowa, Kansas, Missouri, Montana, Nebraska, North Dakota, South Dakota, Utah, Wyoming), in partnership with the Southwest Region (Arizona, Arkansas, Louisiana, New Mexico, Oklahoma, Texas), have combined efforts to produce the first cross-regional Supplemental Nutrition Assistance Program Education (SNAP-Ed) report. The SNAP-Ed program delivers evidence-based nutrition education and obesity prevention interventions through a combination of educational strategies and social marketing coupled with policy, system, and environmental (PSE) interventions to promote healthy eating and active lifestyles. Additionally, coordination and collaboration exists between federal, state, and local partners by supporting community and public health approaches ultimately connecting with other sectors of influence. During Fiscal Year 2019, over 35 million people living in nearly 18 million households received SNAP in the United States. Within the Mountain Plains Region, 1.6 million people living in 778,734 thousand households received SNAP, while in the Southwest Region 6.1 million people living in 2.7 million households received SNAP. SNAP-Ed not only supports SNAP's role in addressing food insecurity, but also works to improve healthy eating to prevent or reduce diet-related chronic disease and obesity among SNAP recipients and other eligible low-income individuals. This report provides an overview of the impact each state has in the regions, including reach, partnerships, coalitions, and program activities. Success stories are also included to illustrate the positive changes from SNAP-Ed programs. [The report was coordinated by Heidi LeBlanc and Casey Combs and edited by Kali McCrackin Goodenough.
