Summary

The goal of this study is to determine the relationship between produce prescription program 'dose' on benefit redemption, food insecurity, and fruit and vegetable consumption. Participants will be randomized to receive one of three fruit and vegetable benefit dose amounts for 6 months ($40, $80, or $110/month).

Detailed description

Emerging evidence from the growing body of research around 'Food is Medicine' interventions shows promise that produce prescriptions (PPR) improve health by enabling purchases of healthy foods, reducing food insecurity, and improving diet quality. However, PPR amounts are often set seemingly arbitrarily, without clear connection to their intended purpose. In this study, investigators will conduct a three-armed randomized trial of 240 participants in Stockton, CA to test the impact of three 'doses' of a fruit and vegetable benefit on benefit redemption, food security, and fruit and vegetable intake. The goal of this study is to determine the relationship between PPR program 'dose' and the key intermediate outcomes of benefit redemption (primary outcome), food insecurity, and consumption of incentivized foods (secondary outcomes). Investigators will also seek to identify any 'ceiling effect' above which further increases in benefit value do not lead to further benefit redemption. This will be highly informative for subsequent PPR research. Investigators will leverage the existing infrastructure of the Vouchers 4 Veggies - EatSF produce prescription program to ensure feasibility.
