项目摘要

The overarching goal of this application is to develop and pilot test a web-based application (app) that will increase access to healthier foods and beverages in low-income urban communities in the United States. Small retail food stores are ubiquitous in low-income urban settings throughout the US and present a unique opportunity to supply surrounding neighborhoods with healthful food options. However, these small stores usually carry few or no foods that are both healthy and affordable. A primary barrier to stocking healthy, affordable foods in small urban food stores is the lack of an adequate distribution network; small store owners generally need to travel on their own to obtain healthy foods and beverages for their stores. Low access to healthy food and high access to food with low nutritional value have been associated with poor diet quality, obesity and chronic disease in many studies. Our research team has worked for more than 16 years in Baltimore to develop, implement, and evaluate chronic disease prevention programs by improving the food environment in low-income communities. Our preliminary formative research assessed the initial acceptability of a mobile app that will enable small urban food store owners to access a range of healthy foods from local wholesalers and producers, and facilitate affordable delivery to their stores. We found high acceptability for an app that would leverage the collective purchasing power of digitally-networked small food stores and introduce cost efficiencies into food delivery. For this NHLBI Clinical Trial Pilot Study (R34), we propose to develop a working web-based Baltimore Urban food Distribution (BUD) app, pilot the app, and evaluate its feasibility and impact on the availability, prices and distribution of healthful foods and beverages in East Baltimore, with the following primary aims: 1) To develop and optimize a technically stable and functional digital strategy to overcome small retail food system constraints common in low-income urban food settings; 2) To pilot the BUD app with Baltimore-based producers/wholesalers and corner stores, and assess its feasibility (i.e., acceptability, operability, perceived sustainability, user satisfaction); and 3) To evaluate the impact of the BUD app on corner store stocking (availability, timeliness, quality), prices, and sales of healthy and unhealthy foods and beverages in a pilot study employing a randomized controlled trial design of 38 corner stores. Secondary aims will examine impact on consumers and a cost-benefit analysis for participating retailers and producers. Findings will permit us to 1) produce a functional and acceptable web-based app, 2) provide preliminary data needed for power calculations for the full-scale trial, 3) generate and refine process evaluation instruments and set standards for implementation, and 4) establish protocols and demonstrate our ability to recruit and retain large numbers of wholesalers, producers, corner stores and consumers. We will assess generalizability of the app by conducting feasibility assessments of the developed app with small store owners and suppliers in other urban settings. The findings from this R34 application are essential to support a full-scale clinical trial, which will test a multi-city deployment of the BUD app and assess its impact on obesity and diet.

这个应用程序的首要目标是开发和试点测试一个基于Web的应用程序（应用程序），增加美国低收入城市社区获得更健康食品和饮料的机会。小型零售食品店在美国低收入城市环境中无处不在，有机会为周围的社区提供健康的食物选择。然而，这些小商店通常携带很少或没有既健康又负担得起的食物。一个主要的障碍，以放养健康，城市小食品店的负担得起的食品是缺乏足够的分销网络;小店主他们一般需要自己旅行，为他们的商店购买健康的食品和饮料。难以获得健康食品和大量获得营养价值低的食品与饮食质量差有关，肥胖和慢性病的关系。我们的研究团队已经在巴尔的摩工作了16年多，开发，实施和评估通过改善低收入社区的食品环境来预防慢性病。我们初步的形成性研究评估了一个移动的应用程序的初步可接受性，食品店老板从当地批发商和生产商那里获得一系列健康食品，价格实惠的送货上门服务我们发现，一个应用程序，将利用集体的高接受度数字联网的小型食品商店的购买力，并将成本效益引入食品交付。为本NHLBI临床试验试点研究（R34），我们建议开发一个基于网络的工作巴尔的摩城市食品配送（BUD）应用程序，试点应用程序，并评估其可行性和对在东巴尔的摩的健康食品和饮料的可用性，价格和分布，与以下主要目标：1）开发和优化技术稳定和功能强大的数字战略，以克服小低收入城市食品环境中常见的零售食品系统限制; 2）试点BUD应用程序，巴尔的摩的生产商/批发商和街角商店，并评估其可行性（即，可接受性，可操作性，感知的可持续性，用户满意度）;以及3）评估BUD应用程序对角落的影响商店库存（可用性，及时性，质量），价格，以及健康和不健康食品和饮料的销售在一项试验性研究中，采用了38家街角商店的随机对照试验设计。次要目标将审查对消费者的影响，并对参与的零售商和生产商进行成本效益分析。调查结果将使我们能够1）制作一个功能和可接受的基于Web的应用程序，2）提供初步数据用于全规模试验的功率计算所需的，3）生成和改进过程评估工具，制定实施标准，4）建立协议，并展示我们招募和留住人才的能力大量的批发商、生产商、街角商店和消费者。我们将评估的普遍性通过与其他地区的小商店业主和供应商对开发的应用程序进行可行性评估，城市环境。这项R34应用的发现对于支持全面的临床试验至关重要，将测试BUD应用程序的多城市部署，并评估其对肥胖和饮食的影响。
