This study pilot-tested combining financial incentives to purchase fruits and vegetables with nutrition education focused on cooking to increase the consumption of fruits and vegetables and improve attitudes around healthy eating on a budget among low-income adults. The goal of the pilot study was to examine implementation feasibility and fidelity, acceptability of the intervention components by participants and effectiveness.
The study design was a pre-post individual-level comparison without a control group. The pilot intervention included two components, a scan card providing free produce up to a weekly maximum dollar amount for use over a 2-month period, and two sessions of tailored nutrition and cooking education. Outcomes included self-reported attitudes about healthy eating and daily fruit and vegetable consumption from one 24-h dietary recall collected before and after the intervention.
Greater Minneapolis/St. Paul area in Minnesota.
Adults (n 120) were recruited from five community food pantries.
Findings indicated that the financial incentive component of the intervention was highly feasible and acceptable to participants, but attendance at the nutrition education sessions was moderate. Participants had a statistically significant increase in the consumption of fruit, from an average of 1·00 cup/d to 1·78 cups/d (P < 0·001), but no significant change in vegetable consumption or attitudes with respect to their ability to put together a healthy meal.
While combining financial incentives with nutrition education appears to be acceptable to low-income adult participants, barriers to attend nutrition education sessions need to be addressed in future research.
本研究初步测试了将购买水果和蔬菜的经济激励措施与以烹饪为重点的营养教育相结合，以增加低收入成年人对水果和蔬菜的消费，并改善其在预算范围内健康饮食的态度。该试点研究的目标是检验实施的可行性和保真度、参与者对干预措施各组成部分的接受程度以及干预的效果。
该研究设计为个体水平的预-后比较，没有对照组。该试点干预包括两个组成部分，一是提供免费农产品的扫描卡，每周最多可使用一定金额，为期两个月；二是两期定制的营养和烹饪教育。结果包括通过干预前后各一次 24 小时膳食回顾收集的关于健康饮食态度和每日水果及蔬菜摄入量的自我报告。
明尼苏达州明尼阿波利斯/圣保罗大都市区。
从五个社区食品储藏室招募了 120 名成年人。
研究结果表明，干预措施的经济激励部分对参与者来说是高度可行和可接受的，但营养教育课程的出勤率中等。参与者的水果摄入量有统计学意义的增加，从平均 1.00 杯/天增加到 1.78 杯/天（P＜0.001），但蔬菜摄入量或其组合健康膳食的能力方面没有显著变化。
虽然将经济激励与营养教育相结合对低收入成年参与者来说是可以接受的，但未来的研究需要解决参加营养教育课程的障碍。
