Identifying effective strategies to promote healthier eating in underserved populations is a public health priority. In this pilot study, we examined the use of financial incentives to increase fresh fruit and vegetable purchases in low-income households (N=29). Participants received pre-paid coupons to buy fresh produce at the study store during the intervention period. Purchases were compared among the three study phases (baseline, intervention, and follow-up). A financial incentive provided by study coupons increased the average weekly purchase of fresh fruit but was less successful with fresh vegetables. These findings underscore the need for specific targeting of vegetable selection and preparation to exploit this strategy more fully.
确定在服务不足人群中促进更健康饮食的有效策略是一项公共卫生优先事项。在这项试点研究中，我们研究了使用经济激励措施来增加低收入家庭（N = 29）购买新鲜水果和蔬菜的情况。在干预期间，参与者收到预付费优惠券，可在研究商店购买新鲜农产品。对三个研究阶段（基线、干预和随访）的购买情况进行了比较。研究优惠券提供的经济激励增加了新鲜水果的平均每周购买量，但对新鲜蔬菜的效果较差。这些发现强调了需要针对蔬菜的选择和准备进行具体定位，以更充分地利用这一策略。
