Abstract

Objectives: We assessed the impact of a rewards-based incentive program on fruit and vegetable purchases by low-income families. Methods: We conducted a 4-phase prospective cohort study with randomized intervention and wait-listed control groups in Philadelphia, Pennsylvania, in December 2010 through October 2011. The intervention provided a rebate of 50% of the dollar amount spent on fresh or frozen fruit and vegetables, reduced to 25% during a tapering phase, then eliminated. Primary outcome measures were number of servings of fruit and of vegetables purchased per week. Results: Households assigned to the intervention purchased an average of 8 (95% confidence interval [CI] = 1.5, 16.9) more servings of vegetables and 2.5 (95% CI = 0.3, 9.5) more servings of fruit per week than did control households. In longitudinal price-adjusted analyses, when the incentive was reduced and then discontinued, the amounts purchased were similar to baseline. Conclusions: Investigation of the financial costs and potential benefits of incentive programs to supermarkets, government agencies, and other stakeholders is needed to identify sustainable interventions.
