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.

拟议的干预措施将专门设计，以满足年轻少女的需要，并防止或尽量减少青春期经常发生的体力活动减少。社会认知理论将被用来指导干预和评估;个人，行为和社会环境因素假设是身体活动的相关性将是干预的目标。干预措施将包括改变体育课的结构和组织、以课堂为基础的PA比赛、以学校为基础的体育活动咨询理事会、家长参与和以社区为基础的规划。测量将在基线（6年级结束），第一年和第二年的计划实施（7日和8日年级结束）后，和一年后的计划完成（9日年级结束）。学校将被招募并随机分配到治疗或对照条件。该研究提出了一项廉价的子研究，以调查饮食摄入量与PA的关系，这是第一个同时检查饮食和PA的基于人群的研究之一。此外，该子研究还将提供有关全年PA模式的重要信息。干预措施的学校部分将包括为女孩提供两种体育课程选择。一种选择将仿照CATCH PE方法，但适用于男女同校的中学环境，重点是在标准体育活动期间增加中度到剧烈体育活动（MVPA）的时间。另一种选择将是一个女孩只选项体育课侧重于个性化的活动，而不是竞争性的活动，同时增加时间的女孩花在MVPA在体育课。课堂部分将补充体育课程，并为课后体育活动提供激励。社区联系将集中于将社区合作伙伴带到学校，以减少参与社区PA机会的障碍，并增加对这些机会的感知。夏季活动将包括在7日和8日年级之间的夏季参加健身/野外营地体验的选项。其他干预活动包括家庭部分，其中包括带有行为线索和奖励措施的优惠券，以提高家庭的PA水平，通过健康课进行PA竞赛，以及为学生、学校工作人员和家庭提供互动网站。
