NCHS Data Brief. 2014 Jan(141):1-8.
Data from the combined National Health and Nutrition Examination Survey (NHANES) and the NHANES National Youth Fitness Survey, 2012. In 2012, about one-quarter of U.S. youth aged 12-15 years engaged in moderate-to-vigorous physical activity for at least 60 minutes daily. Basketball was the most common activity reported among active boys, followed by running, football, bike riding, and walking. Running was the most common activity among active girls, followed by walking, basketball, dancing, and bike riding. The percentage of male youth who were physically active for at least 60 minutes daily decreased as weight status increased. The 2008 Physical Activity Guidelines for Americans, which have been adopted by the First Lady's Let's Move! initiative and the American Academy of Pediatrics, recommend that youth participate in daily moderate-to-vigorous physical activity for at least 60 minutes (1-5). This report presents the most recent national data from 2012 on self-reported physical activity among youth aged 12-15 years, by sex and weight status. This report also describes the most common types of physical activities--outside of school-based physical education (PE) or gym classes--in which youth engage.
数据来自2012年全国健康与营养检查调查（NHANES）和NHANES全国青少年健身调查的合并数据。2012年，约四分之一的12至15岁美国青少年每天进行至少60分钟的中等至剧烈体育活动。篮球是活跃男孩中报告的最常见活动，其次是跑步、足球、骑自行车和散步。跑步是活跃女孩中最常见的活动，其次是散步、篮球、跳舞和骑自行车。随着体重状况的增加，每天进行至少60分钟体育活动的男性青少年比例下降。第一夫人发起的“让我们动起来！”倡议和美国儿科学会采纳的《2008年美国人体育活动指南》建议青少年每天参加至少60分钟的中等至剧烈体育活动（1 - 5）。本报告展示了2012年关于12至15岁青少年自我报告的体育活动的最新全国数据，按性别和体重状况分类。本报告还描述了青少年参与的最常见体育活动类型——在校外体育教育（PE）或体育课之外的活动。
