Study 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).
Primary Outcome
Change in fruit and vegetable consumption from baseline (BL), i.e., before voucher receipt, to the end of the intervention at the end of month 6 (M6), i.e., during the final month of voucher receipt, measured by two 24-hour recalls at each data collection point (BL and M6).
