Summary

Approximately 15% of the US population is enrolled in the Supplemental Nutrition Assistance Program (SNAP), and 50% are children. Although the goal is to improve nutritional health, preliminary data suggest that enrollment in SNAP is associated with obesity and metabolic risks and that SNAP reimburses $4 billion annually for sugar-sweetened beverages (SSBs). This pilot project tests an innovative strategy to reduce purchase of non-nutritive, SSBs by low-income families with children by combining targeted point-of-purchase education with a randomized trial of financial incentives to discourage purchase of unhealthy beverages. The study will take place at a mid-size grocery store that is located in a low-income, Latino community and where 30% of purchases are made with SNAP. Targeted beverage education will be provided to all study subjects with a traffic-light system to identify healthy and unhealthy beverages at the point-of-purchase. Individual beverage purchases will be tracked by electronically stored cash register sales. Supplementary validation of beverage consumption will be assessed by 24 hour dietary recall. Aim 1 is to conduct a randomized controlled trial to compare purchase and consumption of SSBs by families assigned to a financial incentive to reduce purchase of SSBs with families assigned to control (no incentives). Aim 2 is to compare the purchase of SSBs by families in both arms during the study period when they are exposed to the traffic-light system to a baseline period prior to traffic-light education. Results of this project will provide pilot data for larger scale interventions to promote healthy choices among low-income families.
