Proiect Summary: Innovative and culturally appropriate multilevel policy and environmental interventions are greatly needed to address the obesity epidemic in high-risk populations. However, the vast majority of intervention strategies have focused on selected targets and approaches, e.g., educating consumers about healthy food choices, while in many settings reduced access to healthy food choices greatly limits impact. MOPS will test an innovative multi-level intervention, which directly addresses the complex systems associated with childhood eating behaviors and adiposity. Our overarching goal is to develop and evaluate a community based obesity prevention program, which operates at multiple levels of an urban food system (policy, wholesaler, corner stores, carryout, household, individual; in Baltimore, MD), and will improve the healthy food supply chain to increase affordability, availability, purchasing and consumption of healthy foods within lowincome minority neighborhoods. Our proposed research will include stakeholders/ partners at different levels, e.g., the policy, wholesaler, retailer, adult caregiver, and individual child levels, and then develop, implement, and assess a two year multi-level systems-based child obesity prevention strategy targeting minority and low income children (predominantly AA). Thirty low-income, predominantly AA geographic zones will be identified ("healthy eating zones"). Half of these zones will be randomized to intervention, while the other half will be control. Within each intervention zone we will work with at least 5 small food stores and prepared food sources to increase access to healthy foods through wholesaler discounts, display point of purchase promotional materials, and provide nutrition and food preparation education targeting youth and caregivers. We will work with local policymakers to institutionalize and sustain these changes. The project will evaluate the impact of the program on: a) healthy food pricing and availability, b) low income African American adult food purchasing and preparation, and c) low-income African American youth diet, and associated psychosocial factors. The proposed intervention trial directly addresses the RFA by utilizing a systems-based approach to test and evaluate structural interventions at multiple levels.

研究摘要：在高风险人群中，非常需要进行创新和文化上适当的多层次政策和环境干预措施。但是，绝大多数干预策略都集中在选定的目标和方法上，例如对消费者进行健康食品的选择，而在许多情况下，在许多情况下都会减少获得健康食品选择的机会，极大地限制了影响。 MOP将测试创新的多层次干预，该干预直接解决与儿童饮食行为和肥胖相关的复杂系统。我们的总体目标是开发和评估一个基于社区的肥胖预防计划，该计划在多个级别的城市粮食系统（政策，批发商，角落商店，随身携带，家庭，家庭，个人；在巴尔的摩，医学博士）中运作，并将改善健康食品供应链，以提高可负担性，可用性，可用性，可用性，购买和消费较低的较低含量较小的次要社区内健康食品。我们拟议的研究将包括不同层次的利益相关者/合作伙伴，例如政策，批发商，零售商，成人照顾者和个人级别，然后开发，实施和评估针对少数目标和低收入的两年多级基于系统的基于系统的儿童肥胖策略 儿童（主要是AA）。将确定30个低收入，主要是AA地理区域（“健康饮食区”）。这些区域的一半将被随机分配到干预措施，而另一半将受到控制。在每个干预区内，我们将与至少5家小型食品商店和准备好的食物来源一起工作，以通过批发商的折扣，购买促销材料的显示点来增加健康食品的机会，并提供针对青年和看护者的营养和食品准备教育。我们将工作 与地方决策者一起制度化和维持这些变化。该项目将评估该计划对：a）健康食品定价和可用性，b）低收入非裔美国成人食品购买和准备，以及c）低收入的非裔美国青年饮食以及相关的社会心理因素。拟议的干预试验通过利用基于系统的测试和 评估多个级别的结构干预措施。
