Abstract Lower-income and minority groups face significant health disparities with respect to obesity, cancer, heart disease and other diet-related chronic conditions. Poor diets, low in fruits and vegetables (F&V) and high in saturated fat, sodium and sugar, contribute to many of the health problems faced by vulnerable groups. While socioeconomic status and other individual level factors (i.e., food preferences, time and skills to prepare healthy food, etc.) can lead to reduced F&V consumption, these must be viewed in an environmental context. Compared with higher-income neighborhoods, lower-income and minority neighborhoods are less likely to have stores that sell a variety of F&V and other healthy foods. And when stores are available, produce may not be affordable, high quality or culturally appropriate. Farmers' markets and mobile produce markets (MM) have become increasingly popular strategies to alleviate food access concerns in underserved communities. However, it is unclear if these programs have the necessary components to have an appreciable impact on diet. Our research team recently completed one of the first randomized controlled trials of a MM program called the Veggie Van. Veggie Van was run in partnership with our team and a small non-profit organization in North Carolina; it delivered boxes of fresh, locally grown produce and food-focused education to communities with significant barriers to F&V consumption including availability, affordability, quality and knowledge. In this small cluster-randomized trial in 12 communities (N=201), we saw impressive changes in F&V intake with intervention participants eating almost 1 more cups per day of F&Vs than the control group. Intervention participants also reported increases in perceived access to healthy foods and Veggie Van customers attributed many dietary changes to the MM program. While these results are very promising, we believe it is important to test the effectiveness of the Veggie Van program when implemented by different organizations in multiple communities. If shown to be effective, we can create a research-tested intervention toolkit which can be disseminated to communities across the country. For this research, we will use a request for proposals process to identify 8 organizations nationwide that are well-qualified to implement the Veggie Van model. Organizations will identify appropriate sites for MM deliveries (32 total) and we will randomize them to either an implementation or planning condition. With the help of our team's technical assistance and provided funding, partner organizations will engage community members in the process and initiate a MM program. We will use a Type 1 Hybrid Effectiveness-Implementation to measure effectiveness (diet, BMI, dermal carotenoids) and implementation (customer reach and sales, process measures, qualitative interviews with MM staff). We will also examine sustainability of MM financial models and determine implementation standards (i.e., dose needed to maintain impact) for inclusion in our MM toolkit for future dissemination.

摘要 低收入群体和少数群体在肥胖、癌症、心脏病、 疾病和其他与饮食有关的慢性疾病。饮食不佳，水果和蔬菜（F&V）含量低， 饱和脂肪、钠和糖是造成弱势群体面临的许多健康问题的原因。而 社会经济地位和其他个人层面因素（即，食物偏好、时间和准备技巧 健康食品等）可导致F&V消耗减少，必须从环境角度看待这些问题。 与高收入社区相比，低收入和少数民族社区不太可能 有出售各种F&V和其他健康食品的商店。当商店可用时， 不是负担得起的，高质量的或文化上合适的。农贸市场和移动的农产品市场（MM） 已成为越来越受欢迎的战略，以缓解服务不足社区的粮食获取问题。 然而，目前还不清楚这些计划是否具有必要的组成部分， 饮食.我们的研究小组最近完成了一个名为MM项目的第一个随机对照试验之一， 蔬菜货车。蔬菜货车是与我们的团队和北卡罗来纳州的一个小型非营利组织合作经营的。 卡罗莱纳;它提供了新鲜的，当地种植的农产品和食品为重点的教育，以社区与 F&V消费的重大障碍，包括可用性、可负担性、质量和知识。在这个小 在12个社区（N=201）进行的一项随机分组试验中，我们看到了F&V摄入量的显著变化， 干预参与者每天比对照组多吃1杯F& V。干预 参与者还报告了获得健康食品的感知增加，素食货车客户归因于 MM计划的许多饮食变化。虽然这些结果非常有希望，但我们认为重要的是， 测试蔬菜货车计划在多个不同组织实施时的有效性 社区.如果被证明是有效的，我们可以创建一个经过研究测试的干预工具包， 向全国各地的社区传播。对于本研究，我们将使用征求建议书 在全国范围内确定8个有资格实施蔬菜货车模式的组织。 组织将确定MM交付的适当地点（共32个），我们将随机将其分配到 实施或规划条件。在我们团队的技术援助和提供资金的帮助下， 合作伙伴组织将使社区成员参与这一过程，并启动MM计划。我们将使用 a 1型混合免疫力-实施以测量有效性（饮食、BMI、皮肤类胡萝卜素），以及 实施（客户接触和销售，过程测量，与MM员工的定性访谈）。我们将 还检查MM财务模型的可持续性，并确定实施标准（即，需剂量 以保持影响力），以便纳入我们的MM工具包，供未来传播。
