背景资料：本研究评估了在低收入人群的食品福利计划中，财政激励和购买限制对食品购买的影响。方法：参与者（n=279）被随机分为两组：1）激励-购买水果和蔬菜的30%财政激励与食品福利; 2）限制-不购买含糖饮料，甜烘焙食品，或糖果与食品福利; 3）激励加限制;或4）控制-没有激励或限制。参与者收到一张研究专用借记卡，每月增加资金，持续12周。在16周内收集了食品购买收据。根据收据计算了购买杂货和目标食品类别的总支出。结果：与限制组（$1.7）和对照组（$2.1）相比，激励加限制组（$4.8）每周水果购买量显著增加（p
Background: This research evaluated the effects of financial incentives and purchase restrictions on food purchasing in a food benefit program for low income people.Methods: Participants (n=279) were randomized to groups: 1) Incentive-30% financial incentive for fruits and vegetables purchased with food benefits; 2) Restriction-no purchase of sugar-sweetened beverages, sweet baked goods, or candies with food benefits; 3) Incentive plus Restriction; or 4) Control-no incentive or restrictions. Participants received a study-specific debit card where funds were added monthly for 12-weeks. Food purchase receipts were collected over 16 weeks. Total dollars spent on grocery purchases and by targeted food categories were computed from receipts. Group differences were examined using general linear models.Results: Weekly purchases of fruit significantly increased in the Incentive plus Restriction ($4.8) compared to the Restriction ($1.7) and Control ($2.1) groups (p
