DESCRIPTION (provided by applicant): Obesity has become epidemic in U.S. children and adolescents. An unfortunate consequence of this epidemic is the recent recognition of the metabolic syndrome in adolescents, a condition that was historically an adult entity. The main purpose of the proposed R-21 study is to use Community Based Participatory Research (CBPR) methodology to create, implement and evaluate a culturally relevant and age-appropriate obesity intervention (ACTION) for primarily Hispanic adolescents who are overweight. The intervention will be implemented through Albuquerque Public Schools' School-Based Health Centers (SBHCs). ACTION has 3 primary components that were jointly determined with SBHC providers and students in preparing the current proposal: biweekly clinical encounters with SBHC providers, use of Motivational Enhancement Therapy to help overweight adolescents adopt healthier behaviors (specifically increase fruits and vegetable, decrease high fat foods, decrease high sugar beverages, increase physical activity and decrease sedentary behavior), and use of a community advisory council to develop strategies specific to the Stages of Change which will be delivered by print and DVD media. Additional formative research with teens, parents, and school staff will be conducted to explore the potential social, institutional and policy level mechanisms that can be added to ACTION to support high school students in achieving a healthier lifestyle. Intervention components will be modified as suggested by the community advisory council. To test efficacy of the ACTION intervention in one semester, overweight adolescents who are ready to change will be recruited. The study will employ a quasi-experimental design in which one SBHC will deliver the intervention condition and another SBHC will deliver the control condition. Students will have pre- and post- intervention measurements at both SBHC sites to assess if adolescents in the intervention condition will have improved risk factor profile for metabolic syndrome, improved nutrition and improved physical activity when compared with students in the control condition. Analytical approaches will include both cross-sectional analyses at each point in time, pre-post comparisons within each group and comparison of change between the intervention and control groups. This study will provide formative data on potential social, institutional and policy level mechanisms to support high school students in achieving a healthier lifestyle and pilot data on the efficacy of the developed intervention which will be used to plan and design a full-scale intervention for an R34/R01 submission. PUBLIC HEALTH RELEVANCE: Recent estimate of overweight and obese adolescents, ages 12-19 years, in the U.S. is 11%. Healthy People 2010 has set an objective to reduce the proportion of adolescents who are overweight or obese to 5%. The proposed study, ACTION, will contribute greatly to addressing this critical public health problem of childhood obesity through the innovative mechanism of using School-Based Health Centers.

描述（由申请人提供）：肥胖在美国儿童和青少年中已成为一种流行病。这种流行病的一个不幸后果是，最近人们认识到青少年患有代谢综合征，而这种疾病在历史上是成年人的疾病。拟议的R-21研究的主要目的是使用基于社区的参与性研究（CBPR）方法，为主要是西班牙裔超重青少年创建、实施和评估与文化相关和适龄的肥胖干预（ACTION）。干预措施将通过阿尔伯克基公立学校的校本保健中心（shhcs）实施。ACTION有三个主要组成部分，是在准备当前提案时与shbhc供应商和学生共同确定的：每两周与shbhc提供者进行临床接触，使用动机增强疗法帮助超重青少年采取更健康的行为（特别是增加水果和蔬菜，减少高脂肪食物，减少高糖饮料，增加体育活动和减少久坐行为），并利用社区咨询委员会制定针对改变阶段的具体战略，这些战略将通过印刷和DVD媒体传播。将对青少年、家长和学校工作人员进行进一步的形成性研究，以探索潜在的社会、体制和政策层面的机制，这些机制可以添加到ACTION中，以支持高中生实现更健康的生活方式。干预措施的组成部分将根据社区咨询委员会的建议进行修改。为了在一个学期内测试ACTION干预的效果，将招募准备改变的超重青少年。该研究将采用准实验设计，其中一个shbhc将提供干预条件，另一个shbhc将提供控制条件。学生将在两个shbhc地点进行干预前和干预后的测量，以评估干预条件下的青少年与对照组的学生相比，是否会改善代谢综合征的风险因素、改善营养和改善体育活动。分析方法将包括每个时间点的横断面分析，每组内的前后比较以及干预组和对照组之间变化的比较。本研究将提供潜在的社会、制度和政策层面机制的形成性数据，以支持高中生实现更健康的生活方式，并提供已开发干预措施有效性的试点数据，这些数据将用于规划和设计R34/R01提交的全面干预措施。公共卫生相关性：最近估计美国12-19岁的超重和肥胖青少年占11%。《2010年健康人》制定了一项目标，将超重或肥胖青少年的比例降至5%。拟议的研究，ACTION，将通过使用校本保健中心的创新机制，对解决儿童肥胖这一关键的公共卫生问题作出巨大贡献。
