妇女、婴儿和儿童特殊补充营养计划 (WIC) 所服务的成年人的蔬菜摄入量低于建议水平。本研究的目的是确定一种新颖的、理论驱动的、从农场到 WIC 的促进蔬菜摄入的干预措施是否有望取得成功，因此是否适合进行功效测试。从 2019 年 6 月到 2020 年 1 月，干预措施在 3 个 WIC 机构地点进行了试点（其中一个随机分配到干预研究组，两个分配到对照组），这些机构根据服务参与者的规模和人口统计数据的相似性进行选择。参与者于 2019 年 6 月 3 日至 2019 年 8 月 1 日期间招募，主要是西班牙裔成年人，由位于新泽西州人口稠密城区的一家大型 WIC 机构提供服务（160 名在干预地点注册，137 名在对照地点注册）。该干预措施将以行为为重点的指导和讲义与基于 WIC 的农贸市场的介绍、地区农贸市场的实地考察、旅行前后的电话辅导和支持以及食谱演示和品尝结合起来。主要结果是蔬菜摄入量（使用真皮类胡萝卜素作为摄入生物标志物并通过自我报告进行客观测量）以及通过 WIC 农贸市场营养计划 (FMNP) 提供的在农贸市场购买水果和蔬菜的代金券的兑换（使用 WIC 提供的数据进行客观评估）。使用针对基线蔬菜摄入量和协变量进行调整的线性混合效应模型，在干预中期和干预后（分别是基线后 3 个月和 6 个月）检查蔬菜摄入量的组间差异。使用逻辑回归分析将 FMNP 优惠券兑换与研究组和协变量相关联。在干预中期，客观测量的蔬菜摄入量在对照组参与者中高于干预组；各组自我报告的摄入量没有差异。干预后，与对照组相比，干预组参与者客观测量和自我报告的蔬菜摄入量更高。接受干预与 FMNP 代金券兑换的可能性更大相关。干预组的优惠券兑换率为 87%，对照组为 28%（OR = 17.39，95% CI [8.64，35.02]）。干预措施、蔬菜摄入量和 FMNP 优惠券兑换之间存在有意义的关联，表明该计划适合进行功效测试。
Vegetable intake is below recommended levels among adults served by the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). The aim of this study was to determine whether a novel, theory-driven, farm-to-WIC intervention to promote vegetable intake showed promise of being successful and is therefore appropriate for efficacy testing. From June 2019 to January 2020, the intervention was piloted in 3 WIC agency sites (one randomized to the intervention study group and two to the control group) selected based on similarity in size and the demographics of participants served. Recruited between June 3, 2019 and August 1, 2019, participants were 297 primarily Hispanic adults served by a large WIC agency located in a densely populated urban area in New Jersey (160 were enrolled at the intervention site and 137 at control sites). The intervention combined behaviorally focused instruction and handouts with the introduction of a WIC-based farmers’ market, field trips to an area farmers’ market, telephone coaching and support before and after trips, and recipe demonstrations and tastings. The primary outcomes were vegetable intake (measured objectively using dermal carotenoids as a biomarker of intake and via self-report) and the redemption of vouchers provided through the WIC Farmers’ Market Nutrition Program (FMNP) for fruit and vegetable purchases at farmers’ markets (objectively assessed using data provided by WIC). Between-group differences in vegetable intake were examined at mid- and post-intervention (3 and 6 months post-baseline, respectively) with linear mixed-effects models adjusted for baseline vegetable intake and covariates. Logistic regression analysis was used to relate FMNP voucher redemption to study group and covariates. At mid-intervention, objectively measured vegetable intake was higher among participants in the control group as compared to the intervention group; self-reported intake did not differ by group. Post-intervention, objectively measured and self-reported vegetable intake were higher among participants in the intervention group as compared to the control group. Receipt of the intervention was associated with a greater likelihood of FMNP voucher redemption. Voucher redemption rates were 87% in the intervention group and 28% in the control group (OR = 17.39, 95% CI [8.64, 35.02]). Meaningful associations found between the intervention, vegetable intake, and FMNP voucher redemption suggest that the program is appropriate for efficacy testing.
