Abstract This administrative supplement will support the development of Christina Kasprzak’s research and professional skills and provide her with postdoctoral training. There are no proposed changes to the scope or human subjects of the parent grant and the abstract remains as follows: 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. 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. The research team recently completed one of the first randomized controlled trials of a MM program called the Veggie Van (VV). VV 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), the team 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 VV customers attributed many dietary changes to the MM program. While these results are very promising, it is important to test the effectiveness of the VV program when implemented by different organizations in multiple communities. If shown to be effective, the team can create a research-tested intervention toolkit which can be disseminated to communities across the country. For this research, they identified 8 organizations nationwide that are well-qualified to implement the VV model. Organizations will identify appropriate sites for MM deliveries (32 total), which will be randomized to either an implementation or planning condition. With the help of the team’s technical assistance and provided funding, partner organizations will engage community members in the process and initiate a MM program. The research team 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). They will also examine sustainability of MM financial models and determine implementation standards (i.e., dose needed to maintain impact) for inclusion in their MM toolkit for future dissemination.

摘要 这一行政补充将支持克里斯蒂娜Kasprzak的研究和专业的发展， 技能，并为她提供博士后培训。没有对范围或人 家长补助金和摘要的主题仍然如下：低收入和少数群体面临 在肥胖、癌症、心脏病和其他与饮食有关的慢性疾病方面， 条件饮食不佳，水果和蔬菜（F&V）含量低，饱和脂肪、钠和糖含量高， 造成弱势群体面临的许多健康问题。虽然社会经济地位和其他 个体水平因子（即，食物偏好、准备健康食物的时间和技能等）可导致减少 F&V消费，这些必须在环境背景下看待。与高收入相比 社区，低收入和少数民族社区不太可能有商店出售各种 F&V和其他健康食品。当商店可用时，产品可能不是负担得起的，高质量的， 文化上合适。农贸市场和移动的农产品市场越来越受欢迎 在服务不足的社区缓解粮食获取问题的战略。然而，目前尚不清楚这些 这些计划有必要的组成部分，对饮食产生明显的影响。研究团队最近 完成了一个名为蔬菜货车（VV）的MM项目的首批随机对照试验之一。VV 向社区提供新鲜的本地种植的农产品和以食品为重点的教育， F&V消费的障碍包括可用性、可负担性、质量和知识。在这个小小的星团里- 在12个社区（N=201）的随机试验中，研究小组发现干预后F&V摄入量发生了显著变化 参与者每天比对照组多吃1杯F& V。干预参与者还 据报道，健康食品和VV客户感知获得的增加归因于许多饮食变化， MM计划。虽然这些结果非常有希望，但测试验证与确认的有效性非常重要 当由多个社区的不同组织实施时，如果被证明是有效的， 团队可以创建一个经过研究测试的干预工具包，该工具包可以分发给整个社区， 国家在这项研究中，他们在全国范围内确定了8个有资格实施 VV模型。组织将确定MM分娩的适当地点（共32个），这些地点将随机分配至 无论是实施还是规划条件。在团队的技术帮助下， 资金，合作伙伴组织将在这个过程中吸引社区成员，并启动一个MM计划。的 研究小组将使用1型混合免疫力实现来测量有效性（饮食，BMI， 真皮类胡萝卜素）和实施（客户覆盖和销售，过程测量，定性访谈 MM工作人员）。他们还将检查MM财务模型的可持续性，并确定实施情况 标准（即，维持影响所需的剂量），以便纳入其MM工具包，供今后传播。
