Evaluating the Implementation and De-Implementation of Pandemic Era SNAP Expansion on Diet and Health: A Mixed Methods Project - The Supplemental Nutrition Assistance Program (SNAP) has played a central role in reducing food insecurity during the pandemic. Since March 2020, SNAP eligibility was expanded, SNAP benefits increased, and SNAP administrative burden was reduced. By March 2023, most pandemic-era SNAP changes were discontinued, leading to measurable implications for food insecurity and health. There are significant knowledge gaps about the implementation and subsequent de-implementation of pandemic-era SNAP changes and their effects on the health of SNAP participants. The overall objective of this application is to evaluate the effects of implementation and de-implementation of pandemic-era SNAP expansion on adult diet-related health outcomes using a mixed methods approach that builds on the project team’s extensive existing work. The central hypothesis is that the onset of SNAP expansion led to improved dietrelated health outcomes (e.g., BMI, self-rated health status, anxiety, depression), mediated by higher diet quality, lower food insecurity, and higher food expenditures; the sunset of SNAP expansion adversely affected health through these same pathways. In Aim 1, the project team will create a novel comprehensive database to document states’ implementation and deimplementation of SNAP changes from 2020 to 2023 through surveys and focus groups with SNAP staff. In Aim 2, the project team will conduct a survey and in-depth interviews with SNAP participants to understand how these changes impacted program utilization, food insecurity, and dietary intake. Finally, in Aim 3, robust methods for causal inference will be applied to three large datasets to examine SNAP expansion on adult diet-related health (e.g., BMI, self-rated health status, anxiety, depression) and intermediate outcomes (e.g., diet quality, food security, food expenditures). This project will employ a sequential mixed methods study design to integrate data across all aims and add context and richness to the interpretation of the results. This rigorous evaluation will provide evidence for clinical providers and health care systems to identify actionable strategies to reduce food insecurity, thereby supporting improved cardiometabolic health and lowering medical costs.
