Summary

We aim to examine whether a purchasing incentive for healthy foods has the same effect on dietary intake in a community with and a community without a purchasing penalty for unhealthy foods. We will perform a randomized non-inferiority trial in two locations, San Francisco (SF) and Los Angeles (LA) to test whether a voucher for purchasing fresh fruits and vegetables has a similar effect in LA and in SF, where the former does not but the latter does have a tax on sugar-sweetened beverages. Participants will be recruited from 4 neighborhoods (N=312) with 2 SF neighborhoods (exposed to the SSB tax) and 2 LA neighborhoods (not exposed to the SSB tax).

Interventions

BEHAVIORAL

Fruit and vegetable voucher

Participants will receive four vouchers, each dated for a month, to be used on fruits and vegetables at specified local corner stores, supermarkets, and farmer's markets for a duration of six months. Each study participant will have the same intervention, as this is a non-inferiority trial to compare voucher use in LA and test whether the nutritional effects of that use are non-inferior to use in SF.
