PROJECT SUMMARY/ABSTRACT The overarching objective of this trial is to test the impact of a full-service mobile food market (“a grocery store on wheels”) on diet quality, food insecurity (i.e., uncertain or not enough access to food for a healthy life) and food purchases in underserved communities. We will also explore personal, social, behavioral, and environmental factors that may influence adoption of mobile market shopping. The long-term goal of our work is to increase equity in diet/weight-related health outcomes by improving access to and intake of healthy foods. Currently, individuals from racial/ethnic minority backgrounds and those who experience low incomes are disproportionately impacted by poor nutrition and diet/weight-related health outcomes such as type 2 diabetes and high blood pressure. Lack of affordable, healthy food access and food insecurity are believed to be important contributing factors to these disparities. Mobile food markets have been proposed as a strategy for mitigating these health disparities because they bring low-cost, healthy food directly to underserved populations. Mobile food markets are increasingly available nationally and have been supported by state legislation, but little is known about their effectiveness. Full-service mobile markets may improve multiple aspects of the diet by providing foods to meet all dietary needs through a convenient one-stop shop. The full- service mobile market to be tested in this proposal (Twin Cities Mobile Market) sells staple foods from a bus that regularly visits low-income neighborhoods. Foods are sold at prices 10% below those of grocery stores. SNAP/EBT is accepted, and a state-funded fruit/vegetable incentive program (Market Bucks) is available to shoppers. Working in partnership with our community team members, we will enroll 6 community sites (clusters) in two waves (12 total sites/clusters) and recruit 20 participants per site (N=240). We will collect baseline data and randomize sites to either receive the full-service mobile market intervention or serve as the waitlist control. We will then implement the full-service mobile market at intervention sites, follow participants for one year, and collect follow-up data. After follow-up data collection, waitlist control sites will receive the full- service mobile market intervention. For Aim 1, changes in diet quality (our primary outcome measured with the Health Eating Index-2015) and food insecurity (measured with the 18-item U.S. Adult Food Security Survey Module) will be assessed. For Aim 2, changes in food purchases will be objectively measured by collecting one month of food purchase receipts at baseline and follow-up data collection. We will also assess mobile market food purchases during the implementation period with customer loyalty cards. For Aim 3, we will explore the factors that influence adoption of mobile market shopping. Findings will provide evidence on the effectiveness of a full-service mobile market to address disparities around diet, food security, and food purchasing outcomes. This innovative research will provide timely evidence to inform mobile market sustainability, policy, and legislative decisions.

项目总结/摘要 本试验的首要目标是测试提供全方位服务的移动的食品市场（“杂货店 “车轮上”）对饮食质量，粮食不安全（即，不确定或没有足够的食物来维持健康的生活）， 在服务不足的社区购买粮食。我们还将探讨个人，社会，行为， 可能影响采用移动的市场购物的环境因素。我们工作的长期目标 是通过改善健康食品的获取和摄入来增加饮食/体重相关健康结果的公平性。 目前，来自种族/少数民族背景的个人和那些经历低收入的人 不成比例地受到营养不良和饮食/体重相关健康结果的影响，如2型糖尿病 还有高血压人们认为，缺乏负担得起的健康食品和粮食不安全是 造成这些差异的重要因素。移动的食品市场已被提议作为一项战略， 减少这些健康差距，因为它们将低成本，健康的食品直接带到服务不足的地区， 人口。移动的食品市场在全国范围内越来越多，并得到了国家的支持。 立法，但对其有效性知之甚少。全业务移动的市场可能会改善多个 通过方便的一站式商店提供满足所有饮食需求的食品，完整的- 本提案中测试的服务移动的市场（双城移动的市场）在公交车上销售主食 定期走访低收入社区食品的价格比杂货店低10%。 接受SNAP/EBT，并提供国家资助的水果/蔬菜奖励计划（市场巴克斯）， 购物者。与我们的社区团队成员合作，我们将招募6个社区网站 （集群）在两个波（共12个站点/集群）和招募20名参与者每个站点（N=240）。我们将收集 基线数据，随机分配站点，以接受全方位移动的市场干预或作为 waitlist控件。然后，我们将在干预地点实施全方位服务的移动的市场， 为期一年，并收集随访数据。在后续数据收集后，等待名单对照研究中心将收到完整的- 服务移动的市场干预。对于目标1，饮食质量的变化（我们的主要结果用 健康饮食指数-2015）和粮食不安全（用18项美国成人粮食安全调查衡量） 模块）进行评估。就目标2而言，将通过收集一个 基线和随访数据收集时的食品购买收据。我们还将评估移动的市场 在实施期间用顾客忠诚卡购买食品。对于目标3，我们将探讨 影响采用移动的市场购物的因素。调查结果将提供有效性的证据 全方位服务的移动的市场，以解决围绕饮食，粮食安全和粮食购买结果的差异。 这项创新研究将提供及时的证据，为移动的市场的可持续性、政策和 立法决定。
