Abstract

Food and nutrition insecurity disproportionately impact low-income households in the United States, contributing to higher rates of chronic diseases among this population. Addressing this challenge is complex because of various factors affecting the availability and accessibility of nutritious food. Short value chain (SVC) models, informally known as local food systems, offer a systemic approach that aims to optimize resources and align values throughout and beyond the food supply chain. Although specific SVC interventions, such as farmers markets, have been studied individually, a comprehensive review of SVC models was pursued to evaluate their relative impact on food security, fruit and vegetable intake, diet quality, health-related markers, and barriers and facilitators to participation among low-income households. Our systematic literature search identified 37 articles representing 34 studies from 2000–2020. Quantitative, qualitative, and mixed-method studies revealed that farmers market interventions had been evaluated more extensively than other SVC models (i.e., produce prescription programs, community-supported agriculture, mobile markets, food hubs, farm stands, and farm-to-school). Fruit and vegetable intake was the most measured outcome; other outcomes were less explored or not measured at all. Qualitative insights highlighted common barriers to SVC use, such as lack of program awareness, limited accessibility, and cultural incongruence, whereas facilitators included health-promoting environments, community cohesion, financial incentives, and high-quality produce. Social marketing and dynamic nutrition education appeared to yield positive program outcomes. Financial incentives were used in many studies, warranting further investigation into optimal amounts across varying environmental contexts. SVC models are increasingly germane to national goals across the agriculture, social, and health care sectors. This review advances the understanding of key knowledge gaps related to their implementation and impact; it emphasizes the need for research to analyze SVC potential comprehensively across the rural-urban continuum and among diverse communities through long-term studies of measurable health impact and mixed-method studies investigating implementation best practices.

This trial was registered at PROSPERO as CRD42020206532.

解决低收入人群粮食和营养安全问题的地方粮食系统方法:系统回顾
在美国,粮食和营养不安全对低收入家庭的影响尤为严重,导致这一人群的慢性病发病率较高。由于影响营养食品的可获得性和可及性的因素多种多样,应对这一挑战十分复杂。短价值链(SVC)模式被非正式地称为地方食品系统,它提供了一种系统性方法,旨在优化资源并调整整个食品供应链内外的价值。尽管已经对农贸市场等具体的短价值链干预措施进行了单独研究,但我们仍对短价值链模式进行了全面审查,以评估其对粮食安全、水果和蔬菜摄入量、饮食质量、健康相关指标以及低收入家庭参与障碍和促进因素的相对影响。我们的系统性文献检索发现了 37 篇文章,代表了 2000-2020 年间的 34 项研究。定量、定性和混合方法的研究显示,农贸市场干预措施的评估范围比其他SVC模式(即农产品处方计划、社区支持农业、流动市场、食品中心、农场摊位和农场到学校)更广。水果和蔬菜摄入量是衡量最多的结果;对其他结果的探讨较少或根本没有衡量。定性分析强调了使用 SVC 的常见障碍,如缺乏计划意识、可及性有限和文化不协调,而促进因素包括促进健康的环境、社区凝聚力、经济激励措施和优质农产品。社会营销和动态营养教育似乎产生了积极的计划成果。许多研究都采用了经济激励措施,因此有必要进一步研究不同环境背景下的最佳激励措施。SVC模式与国家在农业、社会和医疗保健领域的目标越来越密切相关。本综述加深了人们对有关其实施和影响的关键知识差距的理解;它强调了研究的必要性,即通过对可衡量的健康影响的长期研究和调查实施最佳实践的混合方法研究,全面分析SVC在城乡连续性和不同社区中的潜力。

期刊介绍: Advances in Nutrition (AN/Adv Nutr) publishes focused reviews on pivotal findings and recent research across all domains relevant to nutritional scientists and biomedical researchers. This encompasses nutrition-related research spanning biochemical, molecular, and genetic studies using experimental animal models, domestic animals, and human subjects. The journal also emphasizes clinical nutrition, epidemiology and public health, and nutrition education. Review articles concentrate on recent progress rather than broad historical developments. In addition to review articles, AN includes Perspectives, Letters to the Editor, and supplements. Supplement proposals require pre-approval by the editor before submission. The journal features reports and position papers from the American Society for Nutrition, summaries of major government and foundation reports, and Nutrient Information briefs providing crucial details about dietary requirements, food sources, deficiencies, and other essential nutrient information. All submissions with scientific content undergo peer review by the Editors or their designees prior to acceptance for publication.
