DESCRIPTION (provided by applicant): Over the past 20 years, obesity rates in U.S. children and youth have skyrocketed. National studies show that disparities exist where racial/ethnic minorities and those from a low-income are at higher risk for being overweight or obese. Design, implementation and dissemination of effective school-based prevention programs are critical to addressing these disparities in the obesity epidemic, however few successful models exist. Interventions that are both informed by community partners using a CBPR approach and are comprehensive, and those that include the integration of individual (physical activity behaviors), social (PE teacher curriculum training activities) and environmental (improved school PE equipment) factors have greater success in achieving long-term effects on children's obesity-related behaviors and cognitive performance, especially among medically underserved areas/populations (MUA/P). Resulting from a partnership with the UCLA School of Nursing, the Los Angeles Unified School District (LAUSD) we propose to assess the impact of a middle-school based environmental and curriculum intervention on physical activity and fitness behaviors and standardized achievement test scores among MUA/P youth. This research also examines whether the effects of the intervention vary by gender and ethnicity. The proposed environment and curriculum, coordinated school health program will consist of three components: (1) the SPARK Middle School Physical Education and Nutrition (M-SPAN) Program, 2) professional development (PD) and curriculum training for PE teachers; and 3) provision of quality PE equipment. This study uses a cluster randomized controlled trial design at 24 MUA/P middle schools in the LAUSD with repeated measures (pre-program, mid-program, immediate post-program) and random assignment to the intervention. M-SPAN is an evidenced-based program and is recommended by the CDC to decrease childhood obesity. In order to enhance M-SPAN, SPARK has created PE equipment to match the activities in M-SPAN. The curriculum intervention entails the combination of SPARK Active Recreation and LAUSD PE Standards curricula and will be delivered once a month over 11 months of each of the two intervention years (total 22 months). The project design will be implemented in two waves. Wave I (with 6 sites from each study condition) will run from Years 1-3 and Wave II (with 6 sites from each study condition); will run from Years 2-4. The study aims will be evaluated with objective and subjective activity measures including SOPLAY (System for Observing Plan and Leisure Activity in Youth), physical fitness via the FitnessGram assessment, measured by body composition (decreased BMI and skinfold thickness), aerobic fitness (one mile run), and muscular strength/endurance (curl-up and pull-up) as well as standardized achievement test scores. A small subsample of youth from intervention schools (n=3,960) will also be assessed for physical activity via a modified Youth Risk Behavior Survey (YRBSS), pre-intervention, mid- intervention and immediate post-intervention. For Wave I years 1, 2, and 3 and for Wave II, years 2, 3 and 4.

描述（由申请人提供）：过去 20 年来，美国儿童和青少年的肥胖率急剧上升。国家研究表明，少数种族/族裔和低收入群体超重或肥胖的风险较高，存在差异。设计、实施和传播有效的学校预防计划对于解决肥胖流行中的这些差异至关重要，但成功的模式却很少。由社区合作伙伴采用 CBPR 方法提供信息的全面干预措施，以及整合个人（身体活动行为）、社会（体育教师课程培训活动）和环境（改进学校体育设备）因素的干预措施会取得更大成功对儿童肥胖相关行为和认知表现产生长期影响，特别是在医疗服务不足的地区/人群（MUA/P）中。通过与加州大学洛杉矶分校护理学院、洛杉矶联合学区 (LAUSD) 合作，我们建议评估基于中学的环境和课程干预对 MUA/ 学生的身体活动和健身行为以及标准化成绩测试分数的影响。 P青春。这项研究还探讨了干预措施的效果是否因性别和种族而异。拟议的环境和课程、学校健康协调计划将由三个部分组成：(1) SPARK 中学体育教育和营养 (M-SPAN) 计划，2) 体育教师的专业发展 (PD) 和课程培训； 3）提供优质PE设备。本研究在洛杉矶联合学区的 24 所 MUA/P 中学采用整群随机对照试验设计，采用重复措施（项目前、项目中、项目后立即）和随机分配干预措施。 M-SPAN 是一项基于证据的计划，经 CDC 推荐用于减少儿童肥胖。为了增强M-SPAN，SPARK创建了PE设备来配合M-SPAN的活动。课程干预需要结合 SPARK Active Recreation 和 LAUSD PE 标准课程，并将在两个干预年的每年 11 个月内每月提供一次（总共 22 个月）。该项目设计将分两波实施。第一波（每个研究条件下有 6 个站点）将从第 1-3 年开始，第二波（每个研究条件下有 6 个站点）将运行；将从 2-4 年级开始。研究目标将通过客观和主观活动指标进行评估，包括 SOPLAY（青少年计划和休闲活动观察系统）、通过 FitnessGram 评估身体健康、通过身体成分（降低 BMI 和皮褶厚度）、有氧健身（一英里）进行测量跑）、肌肉力量/耐力（卷曲和引体向上）以及标准化成绩测试分数。来自干预学校的一小部分青少年（n = 3,960）还将通过修改后的青少年风险行为调查（YRBSS）、干预前、干预中和干预后的身体活动情况进行评估。对于第一波，第 1 年、第 2 年和第 3 年；对于第 II 波，第 2 年、第 3 年和第 4 年。
