The proposed intervention will be specifically designed to meet the needs of young adolescent girls and to prevent or minimize the decline in physical activity that frequently occurs during adolescence. Social Cognitive Theory will be used to guide the intervention and evaluation; personal, behavioral, and socio-environmental factors hypothesized to be correlates of physical activity will be the targets of the intervention. The intervention will include changes in the structure and organization of physical education classes, a classroom-based PA competition, a school- based Physical Activity Advisory Council, parental involvement, and community-based programming. Measurements will be taken at baseline (end of 6th grade), following the first and second years of program implementation (end of 7th and 8th grades), and one-year following program completion (end of 9th grade). Schools will be recruited and randomized to treatment or control condition. The study proposes an inexpensive sub-study to investigate dietary intake as it relates to PA, one of the first population-based studies to examine diet and PA simultaneously. In addition, the sub-study will also provide important information on PA patterns throughout the year. The school portion of the intervention will consist of offering girls a choice between two physical education curriculum options. One option will be modeled after the CATCH PE approach, but adapted to a co-educational middle school setting, focused on increasing the amount of time spent in moderate to vigorous physical activity (MVPA) during standard physical education activities. The other option will be a Girls Only Option physical education class focused on individualized activities rather than competitive activities while increasing the amount of time girls spend in MVPA during PE class. The classroom component will complement the PE program and provide incentives for after-school physical activity. The community link will concentrate on bringing community partners to the school to reduce barriers to participating in community PA opportunities and increasing the perceived accessibility of those opportunities. Summer activities will include options for attendance at a fitness/wilderness camp experience during the summer between 7th and 8th grades. Additional intervention activities include a family component featuring coupons with behavioral cues and incentives for increasing PA levels of families, a PA competition administered through health class, and interactive websites for students, school staff and families.

拟议的干预措施将是专门设计的，以满足年轻青少年女孩的需求，并防止或最大程度地减少青春期经常发生的体育活动下降。社会认知理论将用于指导干预和评估；假设是体育活动相关的个人，行为和社会环境因素将是干预的目标。干预措施将包括体育课的结构和组织的变化，基于课堂的PA竞赛，基于学校的体育活动咨询委员会，父母参与以及基于社区的节目。在计划实施的第一年和第二年（7年级和8年级）以及计划完成后一年（9年级结束）之后，将在基线（六年级结束）时进行测量。学校将被招募并随机分配到治疗或控制状态。该研究提出了一个廉价的子研究，以研究与PA有关的饮食摄入量，这是最早基于人群的研究之一，这是同时检查饮食和PA的研究之一。此外，子研究还将全年提供有关PA模式的重要信息。干预的学校部分将包括为女孩提供两种体育课程选项的选择。将在捕获PE方法之后建模一种选择，但适合共同教育中学环境，重点是增加标准体育活动期间中等至有力的体育活动（MVPA）所花费的时间。另一个选择是女孩唯一的选择体育课程，专注于个性化活动，而不是竞争活动，同时增加女孩在PE课程期间在MVPA上花费的时间。课堂组件将补充PE计划，并为课后体育活动提供激励措施。社区链接将集中精力将社区合作伙伴带到学校，以减少参与社区PA机会的障碍，并增加这些机会的可访问性。夏季的活动将包括在7至8年级的夏季参加健身/荒野营的体验的选择。其他干预活动包括一个家庭组件，其中包括带有行为提示的优惠券，以及增加PA家庭水平的激励措施，通过健康班进行管理的PA竞赛以及针对学生，学校工作人员和家庭的互动网站。
