Supplemental Nutrition Assistance Program (SNAP) fruit and vegetable (FV) incentive programs aim to enhance food security and increase FV consumption among low-income United States families. A 2020 scoping review examined their implementation and outcomes, but no updated review has been conducted despite the programs' expansion over the past 5 y.
The purpose of this paper is to provide an updated scoping review characterizing the implementation and outcomes of SNAP FV incentive programs in the United States.
This updated review used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for scoping reviews. MEDLINE, PsycINFO, The Cochrane Library, Web of Science Core Collection, Scopus, and ProQuest Social Science Collection were systematically searched for peer-reviewed studies on FV incentive programs. Out of 4606 articles screened, 55 studies met inclusion criteria. Studies varied by design and included quantitative (n = 39), qualitative (n = 12), and mixed methods (n = 4). Programs were characterized by geographical and retail location type, criteria to earn and redeem incentives, incentive type and incentive amount.
Findings were summarized in articles by program implementation (participant and stakeholder awareness of program existence and function, redemption rates, and barriers and facilitators to program implementation) and program outcomes (food security, purchase and sales, and consumption). Overall, this review found mostly positive outcomes. For example, in 14/17 studies, FV incentive programs were found to increase FV purchases. In 18/25 studies, participants reported an increase in FV consumption.
Continued investment in FV incentive programs is critical in supporting SNAP families' nutrition and health. However, rigorous evaluation of long-term FV consumption, particularly in brick-and-mortar stores, is needed to guide program improvement and scaling.
The protocol for this study was registered in Open Science Framework on 9 April 2024 (https://osf.io/2rk9j) as a scoping review.
补充营养援助计划（SNAP）的水果和蔬菜（FV）激励计划旨在加强粮食安全，并增加美国低收入家庭的FV消费量。2020年的一项范围审查研究了这些计划的实施情况和成果，但尽管这些计划在过去5年中有所扩展，但尚未进行更新审查。
本文旨在提供一份更新的范围审查，描述美国SNAP FV激励计划的实施情况和成果。
本次更新审查采用系统评价和Meta分析的首选报告项目中范围审查的指南。系统检索了MEDLINE、PsycINFO、Cochrane图书馆、科学引文索引核心合集、Scopus和ProQuest社会科学合集，以查找关于FV激励计划的同行评审研究。在筛选的4606篇文章中，55项研究符合纳入标准。研究设计各不相同，包括定量研究（n = 39）、定性研究（n = 12）和混合方法研究（n = 4）。这些计划的特点包括地理和零售地点类型、获得和兑换激励的标准、激励类型和激励金额。
研究结果在文章中按计划实施情况（参与者和利益相关者对计划存在和功能的知晓度、兑换率以及计划实施的障碍和促进因素）和计划成果（粮食安全、购买和销售以及消费）进行了总结。总体而言，本次审查发现的大多是积极成果。例如，在17项研究中的14项中，发现FV激励计划增加了FV购买量。在25项研究中的18项中，参与者报告FV消费量有所增加。
持续投资FV激励计划对于支持SNAP家庭的营养和健康至关重要。然而，需要对长期FV消费进行严格评估，尤其是在实体店中，以指导计划的改进和扩大。
本研究方案于2024年4月9日在开放科学框架（https://osf.io/2rk9j）中登记为范围审查。
