DESCRIPTION (provided by applicant): Obesity rates in American youth have increased dramatically in recent decades. Since obese adolescents are very likely to become obese adults, it is important that the factors that underlie the development of obesity in youth be identified, understood, and targeted in future public health interventions. Numerous authorities have suggested that increasing rates of obesity are, at least in part, due to declining physical activity and increasing participation in sedentary behaviors. It is known that physical activity levels are lower in girls than boys and that physical activity declines with increasing age during adolescence; however, the roles of physical activity and sedentary behavior in preventing adolescent obesity are still not well understood. The Trial of Activity for Adolescent Girls (TAAG) was a multi-center, randomized, controlled field trial that examined the effects of a school plus community intervention on physical activity in middle school girls. Accelerometry was used to objectively measure physical activity in a sample that was diverse in terms of geography, race/ethnicity, socioeconomic status, body composition, physical activity, and other health behaviors. Body composition, types and contexts of physical activity, and psychosocial correlates of physical activity were also measured. The proposed investigation, Longitudinal Assessments in TAAG (LA- TAAG), will track TAAG participants from Louisiana who were measured in 8th grade in spring 2006 and will be re-measured in spring 2009 to observe changes in body composition and levels of physical activity. Further, personal, school, and built environmental factors that may influence physical activity levels and/or weight status will be studied using multi-level models. Finally, we will examine whether persistent stress and anxiety resulting from a disruptive event, such as Hurricane Katrina, could negatively influence physical activity and/or weight status. Project Narrative: Obesity rates in American youth are increasing. More information is needed on how changes in objectively measured physical activity are related to changes in body mass index and percent body fat during adolescence. We will also explore the influence of personal, school and environmental factors, including persistent stress and anxiety that may have resulted from Hurricane Katrina, on these relationships.

描述（由申请人提供）：近几十年来，美国青少年的肥胖率急剧上升。由于肥胖的青少年很可能成为肥胖的成年人，因此在未来的公共卫生干预措施中识别、理解和瞄准导致青少年肥胖的因素非常重要。许多权威人士表示，肥胖率上升至少部分是由于体力活动减少和久坐行为增加所致。众所周知，女孩的体力活动水平低于男孩，并且在青春期，体力活动随着年龄的增长而下降；然而，体力活动和久坐行为在预防青少年肥胖方面的作用仍不清楚。青春期女孩活动试验 (TAAG) 是一项多中心、随机、对照现场试验，旨在检验学校加社区干预对中学生身体活动的影响。加速度测量用于客观测量在地理、种族/民族、社会经济地位、身体成分、身体活动和其他健康行为方面不同的样本中的身体活动。还测量了身体成分、体力活动的类型和背景以及体力活动的社会心理相关性。拟议的 TAAG 纵向评估 (LA-TAAG) 调查将跟踪来自路易斯安那州的 TAAG 参与者，他们于 2006 年春季在八年级接受了测量，并将于 2009 年春季重新测量，以观察身体成分和体力活动水平的变化。此外，将使用多层次模型研究可能影响身体活动水平和/或体重状况的个人、学校和建筑环境因素。最后，我们将研究卡特里娜飓风等破坏性事件造成的持续压力和焦虑是否会对身体活动和/或体重状况产生负面影响。项目叙述：美国青少年的肥胖率正在上升。需要更多信息来了解客观测量的体力活动的变化如何与青春期体重指数和体脂百分比的变化相关。我们还将探讨个人、学校和环境因素（包括卡特里娜飓风可能造成的持续压力和焦虑）对这些关系的影响。
