To test the effectiveness of the Child and Adolescent Trial for Cardiovascular Health (CATCH) program, a randomized trial was conducted in 96 elementary schools in four regions of the United States. Results from the original trial indicated a significant positive effect on the delivery of physical education (PE). All 56 former intervention schools (FI), 20 randomly selected former control schools (FC), and 12 newly selected unexposed control schools (UC) were assessed 5 years postintervention. Results indicate a strong secular trend of increasing moderate to vigorous physical activity (MVPA) in PE classes among both FC and UC schools. The FI schools surpassed the Healthy People 2010 goal for MVPA during PE lesson time (i.e., 50%), whereas the FC and UC schools came close to it. Barriers to implementing CATCH PE included insufficient training and lower importance of PE compared to other academic areas and indicate the need for in-service training.
为测试儿童和青少年心血管健康试验（CATCH）项目的有效性，在美国四个地区的96所小学进行了一项随机试验。原始试验结果表明该项目对体育教育（PE）的实施产生了显著的积极影响。在干预5年后，对所有56所 former intervention schools（FI）、20所随机选择的former control schools（FC）和12所新选择的未暴露对照学校（UC）进行了评估。结果表明，FC和UC学校的体育课中，中等至剧烈身体活动（MVPA）呈强劲的长期上升趋势。FI学校在体育课期间的MVPA超过了《健康人民2010》的目标（即50%），而FC和UC学校接近该目标。实施CATCH体育教育的障碍包括培训不足以及与其他学术领域相比体育教育的重要性较低，这表明需要在职培训。
