Fruit and Vegetable Prescription (FVRx) Programs combine produce prescriptions and nutrition education to reduce fruit and vegetable consumption barriers and promote health among low-income patient populations. This study examined whether a multi-level FVRx intervention model with intensive education improves dietary behaviors, food security, and health outcomes over single-level interventions alone. A 6-month nonrandomized, parallel, controlled trial was conducted with one intervention, FVRx ( = 31) and two comparison groups, Nutrition Education ( = 13) and Control ( = 16). The FVRx group received produce prescriptions (US$1/day/household member) redeemable at a farmer's market, two SNAP-Ed programs, one financial literacy program, and monthly health screenings. The Nutrition Education (NE) group participated in one SNAP-Ed program, and the Control group received safety-net clinic care only. Surveys assessed dietary intake, food security, food purchasing practices, and financial and food resource management. Pre-post clinical biomarkers (blood lipid and hemoglobin A1c) and monthly biometrics (anthropometrics and blood pressure) were measured. Descriptive analysis and one-way analysis of variance (ANOVA) were conducted. Compared with comparison groups, FVRx participants significantly increased the frequency of consuming dark green vegetables, FVRx (0.36 ± 0.72); NE (0.14 ± 0.33); Control (-0.09 ± 0.19) cups/day ( < .05). FVRx participants significantly improved multiple healthful food purchasing practices, and the ability to afford more utilities (FVRx (33%); NE (0%); Control (10%); < .05). Limited changes were observed in food security and clinical biomarker outcomes between groups. Combining expanded nutrition and financial literacy education with produce prescriptions improves low-income adults' financial and food resources, preference, knowledge, purchase, and consumption of locally grown vegetables over single-level interventions.
果蔬处方（FVRx）项目将农产品处方与营养教育相结合，以减少果蔬消费障碍，并促进低收入患者群体的健康。本研究探讨了强化教育的多层次FVRx干预模式与单一层次干预相比，是否能改善饮食行为、食品安全和健康状况。开展了一项为期6个月的非随机、平行对照试验，其中一组为干预组FVRx（n = 31），两组为对照组，即营养教育组（n = 13）和常规护理组（n = 16）。FVRx组接受农产品处方（每户家庭成员每天1美元），可在农贸市场兑换，参加两项补充营养援助计划教育项目、一项金融知识普及项目，并接受每月一次的健康筛查。营养教育（NE）组参加一项补充营养援助计划教育项目，常规护理组仅接受安全网诊所护理。通过调查评估饮食摄入量、食品安全、食品购买行为以及财务和食品资源管理情况。测量临床生物标志物（血脂和糖化血红蛋白A1c）的前后变化以及每月生物特征指标（人体测量指标和血压）。进行描述性分析和单因素方差分析（ANOVA）。与对照组相比，FVRx参与者显著增加了深绿色蔬菜的食用频率，FVRx组为（0.36±0.72）杯/天；NE组为（0.14±0.33）杯/天；常规护理组为（-0.09±0.19）杯/天（P <.05）。FVRx参与者显著改善了多种健康食品购买行为，以及购买更多生活必需品的能力（FVRx组为33%；NE组为0%；常规护理组为10%；P <.05）。各小组之间在食品安全和临床生物标志物结果方面观察到的变化有限。与单一层次干预相比，将扩展的营养和金融知识教育与农产品处方相结合，可改善低收入成年人的财务和食品资源、偏好、知识、购买和当地种植蔬菜的消费情况。
