Abstract:
Identify and categorise different models of community-based fruit and vegetable prescription programs, to determine variation in terms of methodology, target population characteristics, and outcomes measured. Applying the scoping review methodology, ten electronic databases were utilised to identify community-based fruit and vegetable incentive programs. Results were evaluated by two independent reviewers, using Covidence software. All full-text reviews were completed and documented using the PRISMA-ScR guidelines. Search results were stored and reviewed within the Covidence software. Thirty full-text articles were utilised from the 40 206 identified in the search. Target populations were predominantly female, non-white, and low-income. Considerable heterogeneity was found in both study design and quality. Fruit and vegetable vouchers were utilised in 63 % (n 19) of the studies. Prescriptions were primarily provided by community health centres (47 %; n 14) or NGOs (307 %; n 9) and could be redeemed at farmers\' markets (40 %; n 12) or grocery stores (27 %; n 8). When measured, diet quality significantly improved in 94 % (n 16), health outcomes significantly improved in 83 % (n 10), and food security status improved in 82 % (n 10) of studies. Providing financial incentives to offset the cost of fresh fruits and vegetables can increase consumption, improve health outcomes, and improve food security status. The majority of studies showed significant improvements in at least one outcome, demonstrating the effectiveness of community-based fruit and vegetable prescription programs. However, the diversity of measurement techniques and heterogeneity of design, dosage, and duration impeded meaningful comparisons. Further well-designed studies are warranted to compare the magnitude of effects among different program methodologies.
摘要:
识别并分类基于社区的水果和蔬菜处方计划的不同模型,为了确定方法上的差异,目标人群特征,和衡量的结果。应用范围审查方法,十个电子数据库被用来确定基于社区的水果和蔬菜奖励计划。结果由两名独立审核员进行评估,使用Covidence软件。使用PRISMA-ScR指南完成并记录所有全文审查。在Covidence软件中存储和审查搜索结果。从搜索中确定的40206中使用了30篇全文文章。目标人群主要是女性,非白色,和低收入。在研究设计和质量上都发现了相当大的异质性。63%(n19)的研究使用了水果和蔬菜券。处方主要由社区卫生中心(47%;n14)或非政府组织(307%;n9)提供,可以在农贸市场(40%;n12)或杂货店(27%;n8)兑换。测量时,饮食质量显著提高了94%(n16),健康结果显着改善了83%(n10),在82%(n=10)的研究中,粮食安全状况有所改善。提供财政奖励以抵消新鲜水果和蔬菜的成本可以增加消费,改善健康结果,改善粮食安全状况。大多数研究表明,至少一个结果有显著改善,展示以社区为基础的水果和蔬菜处方计划的有效性。然而,测量技术的多样性和设计的异质性,剂量,和持续时间阻碍了有意义的比较。需要进一步精心设计的研究来比较不同计划方法之间的影响程度。
