背景多年来，学校减少了体育课和课间休息时间，转而进行更多的学术指导。由于儿童肥胖水平急剧上升，一些州已开始规定学童的最低体力活动量 (PA)，导致学校寻找替代方法来提高 PA 水平。跨课程体育活动 (PAAC) 是一项为期 3 年的随机临床试验，在小学中纳入中等强度的体育活动，以减少儿童肥胖。本文描述了 PAAC 干预研究的原理、设计和方法。方法：将 22 所小学随机分配到对照条件或干预条件。在随机分配干预条件 (PAAC) 的学校中，普通课堂教师被教导如何将 PA 纳入标准学术课程。在 3 年的学习期间，教师被要求每周积累 90-100 分钟的 PAAC。随机分配到对照组的学校没有改变他们的教学方法。每周收集对课堂 PA 水平的直接观察结果。每年测量两次身高和体重以计算体重指数。结果：两年的干预已经完成，只有一所学校退出了这项研究。其余 21 所学校正在参与最后的干预年。结论：PAAC 干预的结果可能为学校提供另一种方法来提高儿童 PA 水平并减少儿童肥胖。 (C) 2007 Elsevier Inc. 保留所有权利。
Background Over the years schools have reduced physical education and recess time in favor of more academic instruction. Due to the drastic rise in obesity levels among children, some states have begun to mandate minimum amounts of physical activity (PA) that school children receive, causing schools to find alternative methods for increasing PA levels. Physical Activity Across the Curriculum (PAAC) is a 3-year randomized clinical trial incorporating moderate-intensity PA in elementary schools to reduce childhood obesity. This paper describes the rational, design, and methods of the PAAC intervention study.Methods: Twenty-two elementary schools were randomized to either a control or intervention condition. In schools randomized to the intervention condition (PAAC), regular classroom teachers were taught how to incorporate PA into standard academic lessons. Teachers were asked to accumulate 90-100 min/week of PAAC each week through out the 3-year study period. Schools randomized to the control group did not alter their teaching methods. Direct observation of PA levels in the classroom was collected weekly. Height and weight was measured twice a year to calculate BMI.Results: Two years of the intervention have been completed and only one school has left the study. The remaining 21 schools are participating in the final intervention year.Conclusions: The results from the PAAC intervention may provide schools with an alternative method to increase PA levels in children and reduce childhood obesity.
