DESCRIPTION (provided by applicant): The Appalachian region has a population of 23 million residing in 420 counties and 13 states. Forty-two percent of the region's population is rural. Compared to other regions, people living in Appalachia were reported to face a heavier burden from chronic diseases such as obesity, diabetes, and heart disease. The proportions of obese high school students in Southern Appalachia are among the highest in the nation. Health risk habits including unhealthy eating and physical inactivity are often established during adolescence and may contribute significantly to this chronic disease disparity. Although adolescent obesity is an urgent public health issue, effective interventions are few. Therefore, we propose to test an academia-community partnership approach using college students as facilitators to prevent obesity among adolescents. The long-term goal is to establish an effective academia-community partnership program to address adolescent obesity disparity in Southern Appalachia. The specific aims are: 1) To develop a peer- based health education program focusing on establishing positive peer norms and supportive peer relationships toward healthy eating and physical activity among high school students, 2) To test the efficacy of the program, and 3) To explore the mechanisms underlying the program. Twelve (six per each semester) undergraduates at East Tennessee State University will be trained to conduct an eleven-week peer-based health education program as peer facilitators. A cluster-randomized trial design will be used and 6 rural high schools will be randomly assigned to the intervention and control groups. Approximately 1440 adolescents will be included as study subjects. Body mass index (BMI) percentile, dietary behavior, and physical activity among the study subjects will be assessed pre-intervention, at the end of the intervention, and 12 months post-intervention. Mean levels and/or prevalence of differences in the assessments (BMI percentile, obesity status, eating behavior, and physical activity) will be compared between the intervention and control group at the 3 time points (pre-intervention, end of intervention, and 12 months post-intervention). Peer group norms, body image, supportive peer relationships, role modeling, behavioral control/self-efficacy, attitudes, and intentions toward healthy eating and physical activity will be assessed pre-intervention, at the end of the intervention, and 12 months post-intervention. The roles of these factors as mediators of the intervention in modifying adolescents' eating and physical activity behaviors, as well as, body mass index will be examined. This proposed study will provide an important evaluation of an academia-community partnership using college students as facilitators to address adolescent obesity disparity in Southern Appalachia. If proven effective, the proposed program can meet the critical community needs for adolescent obesity prevention by engaging higher education institutes and students in service and fostering within them an ethic of civic responsibility. The program will be easily transferable from research to action without substantial additional resources and will be a sustainable win-win program for both the community and the academy. 1 PUBLIC HEALTH RELEVANCE: This proposed study will provide an important evaluation of a peer-based program. If proven effective, the proposed program can meet the critical community needs for adolescent obesity prevention by engaging higher education students in service and fostering within them an ethic of civic responsibility. A community-campus partnership with this proven program as the core can be built to address adolescent obesity in Southern Appalachia. It would be a sustainable win- win program for both the community and the academy. .

描述（由申请人提供）：阿巴拉契亚地区有 2300 万人口，居住在 420 个县和 13 个州。该地区百分之四十二的人口是农村人口。据报道，与其他地区相比，居住在阿巴拉契亚地区的人们面临着肥胖、糖尿病和心脏病等慢性疾病的更重负担。南阿巴拉契亚地区高中生肥胖比例位居全国最高之列。包括不健康饮食和缺乏身体活动在内的健康风险习惯通常是在青春期养成的，可能会严重影响这种慢性疾病的差异。尽管青少年肥胖是一个紧迫的公共卫生问题，但有效的干预措施却很少。因此，我们建议测试一种学术界与社区合作的方法，利用大学生作为促进者来预防青少年肥胖。长期目标是建立有效的学术界-社区伙伴关系计划，以解决阿巴拉契亚南部青少年肥胖差异问题。具体目标是：1) 制定基于同伴的健康教育计划，重点是在高中生中建立积极的同伴规范和支持性的同伴关系，以实现健康饮食和体育活动，2) 测试该计划的有效性，以及 3) 探索该计划的潜在机制。东田纳西州立大学的 12 名（每学期 6 名）本科生将接受培训，作为同伴协调员开展为期 11 周的同伴健康教育计划。将采用整群随机试验设计，将 6 所农村高中随机分配到干预组和对照组。大约 1440 名青少年将被纳入研究对象。研究对象的体重指数 (BMI) 百分位、饮食行为和体力活动将在干预前、干预结束时和干预后 12 个月进行评估。将在 3 个时间点（干预前、干预结束和干预后 12 个月）比较干预组和对照组之间评估差异的平均水平和/或普遍性（BMI 百分位、肥胖状况、饮食行为和体力活动）。将在干预前、干预结束时和干预后 12 个月评估同伴群体规范、身体形象、支持性同伴关系、角色榜样、行为控制/自我效能、对健康饮食和身体活动的态度和意图。将检查这些因素作为改变青少年饮食和身体活动行为以及体重指数的干预措施的中介作用。这项拟议的研究将对学术界与社区的伙伴关系进行重要评估，利用大学生作为促进者来解决阿巴拉契亚南部的青少年肥胖差异。如果证明有效，拟议的计划可以通过让高等教育机构和学生参与服务并在他们内部培养公民责任道德来满足预防青少年肥胖的关键社区需求。该计划将很容易从研究转化为行动，无需大量额外资源，并且对于社区和学院来说将是一个可持续的双赢计划。 1 公共卫生相关性：这项拟议的研究将为基于同行的计划提供重要的评估。如果证明有效，拟议的计划可以通过让高等教育学生参与服务并培养他们的公民责任道德来满足预防青少年肥胖的关键社区需求。以这一经过验证的计划为核心的社区与校园合作伙伴关系可以解决阿巴拉契亚南部的青少年肥胖问题。对于社区和学院来说，这将是一个可持续的双赢计划。 。
