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.

项目摘要：非常需要创新且适合文化的多层次政策和环境干预措施来解决高风险人群的肥胖流行问题。然而，绝大多数干预策略都侧重于选定的目标和方法，例如，对消费者进行健康食品选择教育，而在许多情况下，获得健康食品选择的机会减少极大地限制了影响。 MOPS 将测试一种创新的多层次干预措施，该干预措施直接解决与儿童饮食行为和肥胖相关的复杂系统。我们的总体目标是制定和评估基于社区的肥胖预防计划，该计划在城市食品系统的多个层面（政策、批发商、街角商店、外卖、家庭、个人；在马里兰州巴尔的摩）运作，并将改善健康食品供应链，以提高低收入少数族裔社区健康食品的可负担性、可用性、购买和消费。我们提出的研究将包括不同级别的利益相关者/合作伙伴，例如政策、批发商、零售商、成人护理人员和儿童个体级别，然后制定、实施和评估为期两年的多层次系统性儿童肥胖预防策略针对少数族裔和低收入群体 儿童（主要是 AA）。将确定 30 个低收入、主要是 AA 的地理区域（“健康饮食区域”）。这些区域的一半将被随机分配进行干预，而另一半将进行控制。在每个干预区内，我们将与至少 5 家小型食品店和预制食品来源合作，通过批发商折扣、展示购买点宣传材料以及针对青少年和护理人员提供营养和食品准备教育来增加获得健康食品的机会。我们将工作 与当地政策制定者合作，将这些变革制度化并维持下去。该项目将评估该计划对以下方面的影响：a) 健康食品的定价和供应，b) 低收入非裔美国人成人食品的购买和准备，以及 c) 低收入非裔美国人青年饮食以及相关的心理社会因素。拟议的干预试验通过利用基于系统的方法来测试和直接解决 RFA 评估多个层面的结构性干预措施。
