背景：健康食品，健康家庭（hhff）是一项在低收入社区农贸市场实施的水果和蔬菜（F&V）暴露/奖励计划，目标是接受美国联邦食品援助的家庭。我们检查了项目对参与者饮食的影响，以及出勤率、人口统计学和饮食变化之间的关系。方法：通过餐饮品鉴和烹饪示范等方式进行体验活动。奖励措施包括电子福利转帐卡（EBT）用户获得40%的F&V奖励，每第三次访问市场购买F&V奖励20美元。在入组时对参与者进行营养行为/读写能力的自我报告调查（n = 425, 46.2%西班牙裔，94.8%女性）。参与者在季节中期（n = 186）和季节结束时（n = 146）在市场抽样进行随访。对出勤率进行了16周的跟踪调查。结果：干预后的参与者报告蔬菜摄入量显著增加（P = 0.005），苏打摄入量显著减少（P = 0.005）。报告F&V增幅最大的参与者参加了6-8次市场，并获得了40美元的奖励。食品和服务方面的食品援助支出没有变化（P = 0.94）；70%的受访者表示家庭对食品和饮料的消费显著增加，这表明补贴增加了食品和饮料的整体购买。参与者报告说，接触活动和奖励同样影响了项目出勤率。结论：在低收入社区的农贸市场，结合暴露活动和适度财政激励的干预措施显示出改善接受联邦食品援助家庭饮食质量的巨大潜力。
Background: Healthy Foods, Healthy Families (HFHF) is a fruit and vegetable (F&V) exposure/incentive program implemented at farmers’ markets in low-income neighborhoods, targeting families receiving US federal food assistance. We examined program effects on participants’ diet and associations between attendance, demographics and dietary change. Methods: Exposure activities included F&V tastings and cooking demonstrations. Incentives included 40% F&V bonus for electronic benefit transfer (EBT) card users and $20 for use purchasing F&V at every third market visit. Self-report surveys measuring nutritional behaviors/literacy were administered to participants upon enrollment (n = 425, 46.2% Hispanic, 94.8%female). Participants were sampled for follow-up at markets during mid-season (n = 186) and at season end (n = 146). Attendance was tracked over 16 weeks. Results: Participants post-intervention reported significantly higher vegetable consumption(P = 0.005) and lower soda consumption (P = 0.005). Participants reporting largest F&V increases attended the market 6-8 times and received $40 in incentives. No change in food assistance spent on F&V (P = 0.94); 70% reported significant increases in family consumption of F&V,indicating subsidies increased overall F&V purchasing. Participants reported exposure activities and incentives similarly affected program attendance. Conclusion: Interventions combining exposure activities and modest financial incentives at farmers’ markets in low-income neighborhoods show strong potential to improve diet quality of families receiving federal food assistance.
