DESCRIPTION (provided by applicant): Over 1.5 million middle school girls in the U.S. are overweight or at risk for becoming overweight. The 10-year NHLBI Growth and Health Study showed that increases in girls' body mass index (BMI) and adiposity were related to a decrease in moderate to vigorous physical activity (MVPA). A sharp decline in girls' MVPA occurs during middle school. The Cochrane Collaboration 2005 review of interventions for preventing obesity in children underscored the need to simultaneously address individual behavior change and the environment in interventions to increase MVPA. The purpose of this study is to test the feasibility of and obtain preliminary evidence of efficacy for a 6-month "Girls on the Move" intervention (guided by the Health Promotion Model and Social Cognitive Theory). The intervention involves motivational, individually tailored counseling plus after- school physical activity (PA) to increase MVPA and cardiovascular (CV) fitness, as well as improve body composition and cognition and affective responses related to MVPA among 6th-grade girls. Specifically, it consists of a 90-minute after-school PA Club that includes MVPA and 6 one-on-one monthly motivational, individually tailored counseling sessions with a registered (school) nurse during the school day to support each girl's continued MVPA. Applying the motivational interviewing communication style, the school nurse will individually tailor the counseling based upon each girl's key responses gleaned from computerized questionnaires assessing cognitive and affective variables related to MVPA. One middle school will be randomly assigned to receive the intervention and another to serve as attention control. School nurses have had limited involvement in school-based PA interventions to date. Our study offers an innovative approach for acquiring essential evidence regarding nurse counseling as a means for assisting girls to increase and maintain MVPA. If successful, this intervention can be translated to other programs (e.g., diabetic education and weight reduction). Specific aims are: 1. Evaluate the feasibility of the intervention related to (1) girls' participation; (2) adherence to protocols; and (3) user and provider (nurse and PA Club instructors) satisfaction. 2. Explore if participants in the intervention group, compared to those in the control group, show improvement in the primary outcome of minutes of MVPA (measured by accelerometer), and also secondary outcomes of self-report of MVPA, CV fitness, BMI, percent body fat, and waist circumference at 6 months. 3. Explore if the primary outcome is mediated by cognitive (perceived benefits of PA, perceived barriers to PA, PA self-efficacy, social support, norms, models) and affective (enjoyment of PA) variables. 4. Explore if participants in the intervention group, compared to those in the control group, have greater minutes of MVPA at 7 months. PUBLIC HEALTH RELEVANCE: Our novel, comprehensive, and theory-driven intervention for middle school girls includes motivational, individually tailored counseling from a school nurse and an opportunity for physical activity at their school. This approach addresses Healthy People 2010 objectives to improve the health of youth by assisting girls to achieve national recommendations for moderate to vigorous physical activity.

描述（由申请人提供）：美国有超过150万名中学女生超重或有超重的风险。为期10年的NHLBI生长与健康研究表明，女孩体重指数（BMI）和肥胖的增加与中度至剧烈体力活动（MVPA）的减少有关。在中学阶段，女生的平均职业成就分数急剧下降。科克伦协作网2005年对预防儿童肥胖干预措施的综述强调，在增加MVPA的干预措施中，需要同时解决个人行为改变和环境问题。本研究的目的是检验为期6个月的“女孩在移动”干预的可行性，并获得初步的疗效证据（以健康促进模式和社会认知理论为指导）。干预措施包括动机，个性化的咨询加上课后体育活动（PA），以增加MVPA和心血管（CV）健身，以及改善身体成分和认知和情感反应与MVPA之间的6年级女孩。具体来说，它包括一个90分钟的课后PA俱乐部，其中包括MVPA和6个一对一的每月激励，个别定制的咨询会议与注册（学校）护士在上学期间，以支持每个女孩的持续MVPA。应用动机访谈的沟通方式，学校护士将根据每个女孩的关键反应，从计算机化的问卷调查评估与MVPA相关的认知和情感变量收集的基础上，个性化的咨询。一所中学将被随机分配接受干预，另一所作为注意力控制。迄今为止，学校护士对以学校为基础的PA干预措施的参与有限。我们的研究提供了一种创新的方法，以获得必要的证据，护士咨询作为一种手段，帮助女孩增加和维持MVPA。如果成功，这种干预可以被转化为其他方案（例如，糖尿病教育和减肥）。具体目标是：1。评估干预措施的可行性，涉及：（1）女孩的参与;（2）遵守协议;（3）用户和提供者（护士和PA俱乐部教员）满意度。2.探索与对照组相比，干预组的参与者是否在MVPA分钟数（通过加速计测量）的主要结局以及6个月时MVPA自我报告、CV健身、BMI、体脂百分比和腰围的次要结局方面有所改善。3.探索主要结局是否由认知（PA的感知益处，PA的感知障碍，PA自我效能，社会支持，规范，模型）和情感（PA的享受）变量介导。4.探索与对照组相比，干预组的参与者在7个月时是否有更长的MVPA分钟。公共卫生相关性：我们的小说，全面的，和理论驱动的干预中学女生包括动机，从学校护士和体育活动在他们的学校的机会量身定制的咨询。这一方法旨在实现2010年“健康人民”的目标，即通过帮助女孩达到国家建议的中等至剧烈体育活动来改善青年的健康。
