DESCRIPTION (provided by applicant): Design, implementation and dissemination of effective school-based prevention programs are critical to addressing the childhood obesity epidemic. Currently few successful models exist for the prevention of childhood obesity. Interventions involving just one influencing factor may not have the desired strong independent effects on children's obesity related behaviors, but may contribute to behavior change if integrated with other individual, social, and environmental changes. This study seeks to evaluate the synergistic impacts of integrating an elementary school-based environment and curriculum intervention on children's obesity related behaviors. This research also examines whether the effects of the intervention on children's physical activity vary by gender, ethnicity, and weight status and whether they extend to outside of school time. The proposed environment and curriculum intervention consists of three components: (1) extensive playground renovations, (2) SPARK Active Recreation implemented on the playground during recess, and (3) and an energy balance curriculum implemented during physical education classes. This study employs a 2 (environmental intervention vs. no environmental intervention) x 2 (curriculum intervention vs. no curriculum intervention) factorial design at 18 inner-city ethnically diverse elementary schools with repeated measures (pre-program, mid-program, immediate post-program, and one year post- program) and random assignment to the curriculum intervention. The environmental intervention, or Learning Landscape Initiative, has transformed school playgrounds into attractive and safe multi-use playgrounds tailored to the needs and desires of the local community. The curriculum intervention entails the combination of the SPARK Active Recreation and Balance First curricula and will be delivered for 8 weeks in the fall and 8 weeks in the spring over the two intervention years. This project design will be implemented in two waves. Wave one (with 3 sites from each study condition) will run from year 1- year 4, and wave 2 (with 3 sites from each study condition) will run from year 2-5. Prior to randomization, 12 Learning Landscape elementary schools will be matched to 12 non-Learning Landscape elementary schools according to the percentage of students receiving free or reduced lunch, student's race and ethnicity, and school size. Six of the matched pairs will be randomly assigned to the curriculum intervention. The study aims will be evaluated with objective physical activity measures using SOPLAY (System for Observing Play and Leisure Activity in Youth) measured at baseline (year 1) and years 2, 3, and 4 for wave 1 and years 2-5 for wave 2. The following objective and subjective assessments will also be collected: (1) A random sub-sample of study participants will be selected to wear accelerometers and provide weight and height measurements at baseline and years 2, 3, and 4 for wave 1 and years 2-5 for wave 2 (n=500). (2) A random sub-sample of grade 4 and 5 student's will be assessed on mediating variables and self-reported leisure time physical activity at baseline and years 2, 3, and 4 for wave 1 and years 2-5 for wave 2 (n=580). (3) Playground environmental characteristics (e.g., spatial proximity of activity areas and size, number, type and quality of activity areas) will be measured at the 18 schools through GIS mapping and direct observation characteristic coding. PUBLIC HEALTH RELEVANCE: Childhood overweight and obesity have detrimental consequences in terms of physical and mental health. The knowledge that results from this study may demonstrate the value of designing multi-component synergistic interventions for the prevention of obesity. Over the long term this may result in a significant decrease in childhood obesity.

描述（由申请人提供）：有效的基于学校的预防计划的设计，实施和传播对于解决儿童肥胖流行病至关重要。目前，很少有成功的模型可以预防儿童肥胖症。仅涉及一个影响因素的干预措施可能不会对儿童肥胖相关行为产生强大的独立影响，但如果与其他个人，社会和环境变化融为一体，可能会导致行为改变。这项研究旨在评估整合基于小学的环境和课程干预对儿童肥胖相关行为的协同影响。这项研究还研究了干预对儿童体育锻炼的影响是否因性别，种族和体重状况而有所不同，以及他们是否扩展到学校时间之外。拟议的环境和课程干预措施包括三个组成部分：（1）在休息期间在操场上实施的广泛的游乐场翻新，（2）（2）（2）以及（3）以及在体育课期间实施的能量平衡课程。这项研究采用2（环境干预与无环境干预措施）x 2（课程干预与无课程干预措施）阶乘设计在18个城市内部种族多样化的小学中，并具有重复措施（前编程，中期，即时，立即后图，后图和一年后计划），并随机分配课程介入。环境干预或学习景观倡议已将学校的游乐场转变为量身定制的有吸引力，安全的多用途游乐场，适合当地社区的需求和欲望。课程干预需要将Spark主动娱乐和平衡第一课程的组合结合在一起，并将在秋季进行8周的交付，在两个干预年份的春季8周。该项目设计将以两波实施。第一波（来自每个研究条件的3个地点）将从1年级开始运行，而第2波（来自每个研究条件的3个地点）将从2 - 5年开始运行。在随机分组之前，根据获得免费或减少午餐，学生种族和种族以及学校规模的学生百分比，将将12个学习景观小学与12个非学习景观小学相匹配。匹配对的六对将随机分配给课程干预。将通过客观的体育活动措施评估该研究的目标，该措施使用SOPLAY（用于观察年轻人的比赛和休闲活动的系统）在基线（第1年）和第1次的第2、3和4年和第2年的第2-5年以及2-5年度进行评估。以下客观评估和主观评估也将用于以下情况：（1）在以下情况下，以下是：（1）将在2个阶段和高度的测量参与者中随机提供，并在3个阶段和高度的次数和高度的次数，并在高度和高度下，并高度的高度和高度。波2（n = 500）的1和2-5年。 （2）将对4级和5级学生的随机子样本进行评估，并在基线时进行中介变量和自我报告的休闲时间体育锻炼，以及第1波1的2、3和4年度以及2-5年的2 - 5年（n = 580）。 （3）将通过GIS映射和直接观察特征编码来测量游乐场环境特征（例如，活动区域和大小，数量，类型和质量的空间接近，活动区域的数量，类型和质量）。公共卫生相关性：童年的超重和肥胖在身心健康方面造成了不利的后果。这项研究产生的知识可能表明，设计多组分协同干预措施以预防肥胖的价值。从长远来看，这可能会导致儿童肥胖大大减少。
