虽然水果和蔬菜中的营养素是正常发育和预防疾病所必需的，但大多数美国儿童的摄入量低于推荐量。由医生开具的水果和蔬菜处方，以换取新鲜农产品，解决了获取和负担能力方面的挑战，同时强调了饮食在促进健康和预防疾病方面的重要作用。密歇根州的第一个专门针对儿童的水果和蔬菜处方计划（FVPP）于2016年在弗林特的一家大型儿科诊所推出，并于2018年扩展到第二家诊所。该计划提供了一个15美元的处方新鲜农产品的所有儿科患者在每次办公室访问。处方药可以在全年开放的农贸市场或当地的移动的市场兑换。目前的研究将评估FVPP对饮食，食品安全和青少年体重状况的影响。将比较基线时具有不同FVPP暴露水平的人口统计学相似的儿科患者组：高暴露（> 24个月）、中等暴露（12-24个月）和既往无暴露。数据收集将侧重于8-16岁的青年。本研究将入组共计700对双胞胎儿童（每个家庭一名护理人员和一名儿童），其中约200对在诊所1（高暴露）; 200对在诊所2（中度暴露），300对在诊所3（无既往暴露）。将向先前没有接触过的儿童介绍FVPP，并在两年内跟踪饮食，食品安全和体重状况的变化。具体目标是（1）比较不同FVPP暴露水平的儿科患者之间的基线饮食、食物安全和体重状况;（2）测量从未暴露于FVPP的儿童在引入FVPP之前和之后的饮食、食物安全和体重状况的变化;以及（3）将初始无暴露组的平均12个月和24个月随访的饮食、食品安全和体重状况测量值与高暴露组的基线测量值进行比较。研究目的的完成将为儿科FVPP的有效性提供证据，并就影响变化所需的暴露持续时间和强度提供见解。本研究于2021年2月23日通过clinicaltrials.gov[ID：NCT 04767282]注册。
Although nutrients in fruits and vegetables are necessary for proper development and disease prevention, most US children consume fewer servings than recommended. Prescriptions for fruits and vegetables, written by physicians to exchange for fresh produce, address access and affordability challenges while emphasizing the vital role of diet in health promotion and disease prevention. Michigan’s first fruit and vegetable prescription program (FVPP) exclusively for children was introduced in 2016 at one large pediatric clinic in Flint and expanded to a second clinic in 2018. The program provides one $15 prescription for fresh produce to all pediatric patients at every office visit. Prescriptions are redeemable at a year-round farmers’ market or a local mobile market. The current study will assess the impact of this FVPP on diet, food security, and weight status of youth. Demographically similar pediatric patient groups with varying levels of exposure to the FVPP at baseline will be compared: high exposure (> 24 months), moderate exposure (12–24 months), and no previous exposure. Data collection will focus on youth ages 8–16 years. A total of 700 caregiver-child dyads (one caregiver and one child per household) will be enrolled in the study, with approximately 200 dyads at clinic 1 (high exposure); 200 dyads at clinic 2 (moderate exposure), and 300 dyads at clinic 3 (no previous exposure). Children with no previous exposure will be introduced to the FVPP, and changes in diet, food security, and weight status will be tracked over two years. Specific aims are to (1) compare baseline diet, food security, and weight status between pediatric patients with varying levels of exposure to the FVPP; (2) measure changes in diet, food security, and weight status before and after never-before-exposed children are introduced to the FVPP; and (3) compare mean 12- and 24-month follow-up measures of diet, food security, and weight status in the initial no exposure group to baseline measures in the high exposure group. Completion of study aims will provide evidence for the effectiveness of pediatric FVPPs and insights regarding the duration and intensity of exposure necessary to influence change. The study was registered through clinicaltrials.gov [ID: NCT04767282] on February 23, 2021.
