DESCRIPTION (provided by applicant): Eating ample amounts of fruits and vegetables (F&V) is associated with a lower risk of chronic disease. Dietary guidelines recommend eating more F&V, but most Americans fall short of recommendations especially low income populations. Cost-effective multilevel interventions that improve access and availability to F&V as well as provide education and change the social environment to increase the F&V intake of underserved population are critically needed. The proposed research will study the efficacy of innovative interventions by building upon a successful pilot F&V delivery intervention that was conducted in worksites. The study will be conducted in 16 subsidized housing projects that will be pair-matched. A random sample of 135 household addresses will be chosen at each of the housing projects. Door-to-door recruitment will take place to enroll 108 households in an evaluation cohort. Individuals who agree will complete a baseline survey as well as 6 and 12 month follow-up surveys. Randomization will occur into one of two intervention groups after the baseline is completed: a Fresh To You group (including delivery of reduced price F&V directly to the housing project by a F&V distribution company, plus educational interventions) vs. a comparison group (receiving an attention placebo intervention and access to Fresh To You after the study). The primary outcome will be F&V consumption. The Specific Aims are: S.A.1 To conduct formative research with low income, ethnically diverse individuals living in subsidized housing projects to inform the adaptation of multi-level interventions to improve F&V intake and evaluation tools and measures. S.A.2 To employ a group randomized trial to study the efficacy of an innovative intervention combining educational interventions with a F&V delivery intervention to increase F&V access and availability on increasing participants' F&V consumption (Fresh To You intervention) compared to a Comparison intervention. We will also examine mechanisms involved in delivery and receipt of programming and the causal pathway of the intervention by addressing the following secondary aims: a) To include extensive implementation process evaluation to determine costs, reach, fidelity and dose and the relationship of these variables with evaluation outcomes; b) To use a mediating variable framework to examine relationships among important psychosocial factors/determinants with changes in F&V consumption.

描述（由申请人提供）：吃大量的水果和蔬菜（F&V）与慢性疾病的风险较低有关。饮食指南建议吃更多的F&V，但大多数美国人没有达到建议，特别是低收入人群。迫切需要采取具有成本效益的多层次干预措施，改善F&V的获取和提供，并提供教育和改变社会环境，以增加服务不足人口的F&V摄入量。拟议的研究将研究创新干预措施的有效性，建立在一个成功的试点F&V交付干预措施，是在工作场所进行。这项研究将在16个补贴住房项目中进行，这些项目将配对。每个房屋项目将随机抽取135个家庭地址。将挨家挨户招募108户家庭参加评估队列。同意的个人将完成基线调查以及6个月和12个月的随访调查。基线完成后，将随机分为两个干预组之一：Fresh To You组（包括由F&V分销公司直接向住房项目提供降价F&V，加上教育干预）与对照组（接受关注安慰剂干预并在研究后获得Fresh To You）。主要结果将是F&V消费。具体目标是：S.A.1对生活在补贴住房项目中的低收入、不同种族的个人进行形成性研究，以告知多层次干预措施的适应情况，以改善F&V的摄入量和评估工具及措施。S.A.2采用一项分组随机试验，研究将教育干预与F&V交付干预相结合的创新干预措施（Fresh To You干预措施）与比较干预措施相比的有效性，以增加参与者的F & V消费量，从而增加F&V的获取和可用性。我们还将审查方案拟订的交付和接收机制以及干预措施的因果途径，为此要实现以下次要目标：（a）包括广泛的执行过程评价，以确定成本、覆盖面、忠实度和剂量以及这些变量与评价结果的关系; B）使用中介变量框架来检查重要的心理社会因素/决定因素与F&V消费变化之间的关系。
