Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess the impact of digital promotions of a Supplemental Nutrition Assistance Program (SNAP) fruit and vegetable incentive program on SNAP participant patronage and sales at farmers' markets. The study will analyze SNAP transactions from zip codes that receive digital promotions compared to zip codes that receive no additional promotions.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Supplemental Nutrition Assistance Program (SNAP) financial incentives for fruits and vegetables (FV) increase FV purchases and consumption with long-term implications for nutrition-related chronic disease. However, many SNAP participants are not aware of these programs, leaving them underutilized. The investigators aim to assess if digital promotions of SNAP incentive programs increase SNAP patronage and sales at farmers' markets. Eligible farmers' markets in the New England Nutrition Incentives Collaborative (NENIC) will receive digital promotions for their SNAP fruit and vegetable incentive programs on the Fresh EBT app and Facebook, randomly assigned to nearby eligible zip codes. Eligible zip codes will be randomized to receive the intervention (digital promotion) or serve as a comparison (no additional promotion) with ads running for 13 weeks (Summer 2020 market season).
