DESCRIPTION (provided by applicant): The increasing prevalence of obesity in U.S. children and adolescents is a major health threat to our society, especially among minority and low social economic status (SES) populations. During adolescence physical activity (PA) decreases and is likely an important contributor to the increasing trend in childhood obesity rates. Little evidence suggests that school-based curriculum interventions lead to increases in overall PA. Thus, this proposal will evaluate the efficacy of an innovative student-centered after-school program for promoting increases PA among underserved adolescents (e.g., minorities, low SES). The student-centered intervention is consistent with Self-Determination (Motivation) Theory and Social Cognitive Theory in that it emphasizes increasing intrinsic motivation and behavioral skills for PA. Adolescents in the student-centered program take ownership in developing the program, select physical activities that generate fun and interest, and generate their own coping strategies for making effective PA changes during a videotaped session. Preliminary data from our group demonstrates the feasibility of the student-centered PA program for increasing moderate-to-vigorous PA in underserved adolescents in South Carolina. The proposed project will use a school-based nested cohort design to evaluate efficacy of a 6-month student-centered program versus typical after-school program on increasing PA in underserved adolescents. Twenty-four middle schools (70 6th graders per school; N=1,680), located in South Carolina will be randomly assigned to one of two after-school programs. The study employs a nested cohort design, with schools, rather than individuals assigned to condition and will be analyzed using repeated measures analysis of covariance techniques as outlined by Murray. We will also examine psychosocial variables (PA self-efficacy, self-concept, motivation, social support, and enjoyment) as potential mediators of the intervention on changes in PA using regression and structural equation modeling techniques as outlined by Baron and Kenny. This study will address an important public health problem that will have implications for decreasing obesity in underserved adolescents.

描述（由申请人提供）：美国儿童和青少年中日益普遍的肥胖是对我们社会的主要健康威胁，特别是在少数民族和低社会经济地位（SES）人群中。在青少年时期，身体活动（PA）减少，可能是儿童肥胖率上升趋势的重要因素。几乎没有证据表明学校课程干预会导致整体PA的增加。因此，本提案将评估一个创新的以学生为中心的课后计划的有效性，以促进服务不足的青少年（例如，少数民族，低社会经济地位）的PA增加。以学生为中心的干预与自我决定（动机）理论和社会认知理论是一致的，强调提高个人助理的内在动机和行为技能。在以学生为中心的项目中，青少年在开发项目中拥有自主权，选择产生乐趣和兴趣的体育活动，并在录像会议期间制定自己的应对策略，以有效地改变PA。我们小组的初步数据证明了以学生为中心的PA计划在南卡罗来纳州服务不足的青少年中增加中等到高强度PA的可行性。拟议的项目将使用基于学校的嵌套队列设计来评估为期6个月的以学生为中心的项目与典型的课后项目在增加服务不足的青少年PA方面的效果。位于南卡罗来纳州的24所中学（每所学校70名六年级学生；N= 1680）将被随机分配到两个课后项目中的一个。该研究采用嵌套队列设计，学校而不是个人分配条件，并将使用Murray概述的协方差技术的重复测量分析进行分析。我们还将使用Baron和Kenny概述的回归和结构方程建模技术，研究社会心理变量（个人行为自我效能、自我概念、动机、社会支持和享受）作为干预个人行为改变的潜在中介。这项研究将解决一个重要的公共卫生问题，这将对减少服务不足的青少年的肥胖产生影响。
