背景：在美国，儿童和青少年肥胖的增加越来越受到关注，在世界上大多数国家都是如此。在过去的40年里，体育活动的减少通常被认为是导致肥胖率上升的原因。方法：我们使用非传统数据源搜索了美国青年体育活动和久坐行为趋势的研究。文献检索进行了积极的通勤，体育教育，高中体育，户外运动。此外，还研究了久坐行为的趋势。结果如下：来自青年危险行为监测系统和其他国家调查的数据，以及交通、教育、电子媒体和娱乐部门的纵向研究显示，有证据表明，几个指标发生了变化。积极的通勤，高中体育教育和户外运动（3至12岁）随着时间的推移而下降，而高中女生的体育参与从1971年到2012年有所增加。此外，电子娱乐和计算机的使用在21世纪世纪的第一个十年中增加。结论：技术和社会的变化影响了美国青年进行的体育活动的类型。这些数据有助于理解与肥胖症上升相关的因素，并提出潜在的解决方案。
Background: Increases in childhood and adolescent obesity are a growing concern in the United States (U.S.), and in most countries throughout the world. Declines in physical activity are often postulated to have contributed to the rise in obesity rates during the past 40 years. Methods: We searched for studies of trends in physical activity and sedentary behaviors of U.S. youth, using nontraditional data sources. Literature searches were conducted for active commuting, physical education, high-school sports, and outdoor play. In addition, trends in sedentary behaviors were examined. Results: Data from the Youth Risk Behavior Surveillance System (YRBSS) and other national surveys, as well as longitudinal studies in the transportation, education, electronic media, and recreation sectors showed evidence of changes in several indicators. Active commuting, high school physical education, and outdoor play (in 3- to 12-year-olds) declined over time, while sports participation in high school girls increased from 1971 to 2012. In addition, electronic entertainment and computer use increased during the first decade of the 21st century. Conclusions: Technological and societal changes have impacted the types of physical activities performed by U.S. youth. These data are helpful in understanding the factors associated with the rise in obesity, and in proposing potential solutions.
