Cost-effectiveness and health equity improvements from excluding sugar-sweetened beverages from the Supplemental Nutrition Assistance Program.

Introduction: Excluding sugar-sweetened beverages (SSBs) from eligible purchases in the Supplemental Nutrition Assistance Program (SNAP) has been proposed as a strategy to improve diet quality and health. This study estimates the cost-effectiveness of this policy and its potential impact on health equity.

Methods: The Childhood Obesity Intervention Cost Effectiveness Study (CHOICES) microsimulation and systematic review process was used in 2024 to estimate the potential impact of excluding SSBs from SNAP-eligible purchases over a ten-year period (2023-2032) for the U.S.

Population: Health outcomes related to excess weight, costs, and relative changes in obesity prevalence by income, race, and ethnicity group in 2032 were estimated.

Results: The policy is projected to be cost-saving, prevent 279,000 cases of obesity (95% UI: 149,000-446,000), and contribute 115,000 (95% UI: 60,100-187,000) quality-adjusted life years gained over ten years among SNAP participants. The policy could save an estimated $2.75 billion in healthcare costs related to excess weight over ten years, resulting in $3.35 in healthcare cost savings per dollar spent on implementation. Reductions in obesity prevalence were estimated to be 3.5 times greater among individuals with income ≤130% of the federal poverty level compared to the overall mean, and 3-3.5 times greater among non-Hispanic Black and Hispanic individuals compared to non-Hispanic white individuals.

Conclusions: Excluding SSBs from SNAP-eligible purchases could be a cost-saving strategy to improve health and health equity between income, racial, and ethnic groups. The U.S. Department of Agriculture could use pilot studies to test the real-world effects of excluding SSBs from SNAP.
