DESCRIPTION (provided by applicant): Consistent with NIH priorities, our long-term objective is to reduce the rates and risk of childhood obesity via school-based nutrition and physical activity policies. We propose to monitor and evaluate how Connecticut's first-ranked School Wellness Policy, in the New Haven Public School district, is implemented and determine its impact on children's obesogenic behaviors, weight outcomes, and school performance. We will evaluate a strategy of implementation at 12 targeted schools using a randomized design. We propose a multi-level assessment of factors that may influence childhood obesity using the Ecological Model as a guiding framework. This ambitious project is possible because of the expertise and strong collaborative partnerships between The New Haven Public Schools and two Yale University research centers: The Rudd Center for Food Policy and Obesity and CARE: Community Alliance for Research and Engagement. This study is designed to significantly advance empirical research on school wellness policies through targeted implementation and measurable impact on student health. Specific Aims are to: (1) track and evaluate a strategy of targeted school implementation of a District Wellness Policy; (2) identify factors that facilitate or impede implementation of The District Wellness Policy; and (3) evaluate the impact of implementation of The School Wellness Policy on obesogenic behaviors and health outcomes as well as school performance. We will implement nutrition and physical activity policies in 12 schools using a randomized 2 x 2 research design. This will permit comparison of unique and synergistic effects of nutrition and physical activity policies on student behaviors and health outcomes. We will follow a cohort of 5th grade students (NH700) annually for 4 years to assess potential changes in student eating behaviors, physical activity levels, and BMI. We use a multi-method approach to collect data and examine predictors of these outcomes from across the ecological framework: student variables, family characteristics, school policies, and neighborhood features (e.g., via environmental mapping and US Census Bureau statistics). This multidisciplinary proposal is synchronous with research objectives articulated in Program Announcement (PA-10-052) School Nutrition and Physical Activity Policies, Obesogenic Behaviors and Weight Outcomes. We directly target implementation and impact of health-related policies in schools; we have an active tracking system to monitor policies; and we focus on minority populations traditionally vulnerable and underserved. As stated by NIH, policy-based approaches to combat obesity in schools exist; however, knowledge is lacking in key areas concerning the optimal policies, key implementation strategies for such policies, and the impact of these policies on important health and social outcomes. The proposed project will advance scientific knowledge and understanding provide important evidence to guide future interventions in schools and communities - translating science to improved health of the public.

描述（由申请人提供）：与 NIH 的优先事项一致，我们的长期目标是通过基于学校的营养和体育活动政策降低儿童肥胖的发生率和风险。我们建议监测和评估康涅狄格州纽黑文公立学区一流的学校健康政策的实施情况，并确定其对儿童肥胖行为、体重结果和学校表现的影响。我们将采用随机设计评估 12 所目标学校的实施策略。我们建议使用生态模型作为指导框架，对可能影响儿童肥胖的因素进行多层次评估。这个雄心勃勃的项目之所以成为可能，是因为纽黑文公立学校和两个耶鲁大学研究中心之间的专业知识和强有力的合作伙伴关系：路德食品政策和肥胖中心以及 CARE：研究和参与社区联盟。本研究旨在通过有针对性的实施和对学生健康的可衡量影响，显着推进学校健康政策的实证研究。具体目标是： (1) 跟踪和评估有针对性的学校实施学区健康政策的策略； (2) 确定促进或阻碍地区健康政策实施的因素； (3) 评估学校健康政策的实施对肥胖行为和健康结果以及学校表现的影响。我们将采用随机 2 x 2 研究设计在 12 所学校实施营养和体育活动政策。这将允许比较营养和身体活动政策对学生行为和健康结果的独特和协同效应。我们将每年跟踪一组五年级学生 (NH700)，为期 4 年，以评估学生饮食行为、体力活动水平和 BMI 的潜在变化。我们使用多种方法来收集数据并检查整个生态框架中这些结果的预测因素：学生变量、家庭特征、学校政策和社区特征（例如，通过环境绘图和美国人口普查局统计数据）。这项多学科提案与计划公告 (PA-10-052) 学校营养和身体活动政策、肥胖行为和体重结果中阐明的研究目标同步。我们直接针对健康相关政策在学校的实施和影响；我们有一个主动跟踪系统来监控政策；我们重点关注传统上弱势且服务不足的少数群体。正如美国国立卫生研究院所述，存在基于政策的方法来对抗学校肥胖；然而，对于最佳政策、此类政策的关键实施战略以及这些政策对重要健康和社会成果的影响等关键领域缺乏了解。拟议的项目将促进科学知识和理解，为指导未来对学校和社区的干预提供重要证据——将科学转化为改善公众的健康。
