背景体育活动对年轻人有许多健康益处。2018年，世卫组织发起了一项关于身体活动的新全球行动--“让更多的人更活跃，让世界更健康”，其中包括到2030年将青少年和成人身体活动不足的全球患病率相对降低15%的新目标。我们描述了目前的患病率和趋势不足的身体活动在上学的青少年年龄在11-17岁的国家，地区和global.Methods我们做了一个汇总分析的横断面调查数据，收集通过随机抽样的样本量至少有100个人，是代表一个国家或定义的国家以下的人口，以及青少年中按性别分列的身体活动不足的报告流行率。必须报告10-19岁年龄范围内至少三个年龄段的患病率。我们估计了2001- 2016年各个国家、世界银行四个收入组、九个地区和全球范围内11-17岁在校青少年（合并和按性别）身体活动不足的患病率。为了得出身体活动不足的标准定义，并调整仅城市的调查范围，我们使用了回归模型。我们估计的时间趋势，使用多层次的混合效应modeling.Findings我们使用的数据来自298个学校为基础的调查，从146个国家，地区和地区，包括160万名学生年龄在11-17岁。在全球范围内，2016年，81-0%（95%不确定区间77-8-87.7）的11-17岁学生身体活动不足（77.6% [76-1-80.4]的男孩和84.7% [83.0-88-21的女孩）。尽管2001年至2016年期间，男孩身体活动不足的患病率显着下降（从2001年的80.1% [78.3-81-61]），但女孩没有显着变化（从2001年的85.1% [83.1-88.0]）。按国家收入组分列，没有明显的模式：2016年活动不足的发生率为84.9%（82.6-88-2）在低收入国家，79.3%在中低收入国家，这一比例为83.9%（79.5-89.2），在中高收入国家为79.4%（74.0-86.2）。2016年活动不足发生率最高的地区是高收入亚太地区，男孩（89.0%，62.8-92.2）和女孩（95.6%，73.7-97.9）。流行率最低的地区是高收入西方国家（男孩72.1%，71.1-73-6）和南亚（女孩77.5%，72-8-89.3）。2016年，有27个国家的女孩活动不足率达到或超过90%，而有两个国家的男孩活动不足率达到或超过90%。需要紧急扩大执行已知有效的政策和方案，以增加青少年的活动。在各级进行投资和发挥领导作用，对可能导致体育活动参与率低和性别差异长期存在的多种原因和不平等现象进行干预，并让青年人自己参与，这对加强所有社区的体育活动机会至关重要。这些行动将改善这一代和未来年轻一代的健康状况，并支持实现2030年可持续发展目标。版权所有（C）2019世界卫生组织;许可人Elsevier。
Background Physical activity has many health benefits for young people. In 2018, WHO launched More Active People for a Healthier World, a new global action on physical activity, including new targets of a 15% relative reduction of global prevalence of insufficient physical activity by 2030 among adolescents and adults. We describe current prevalence and trends of insufficient physical activity among school-going adolescents aged 11-17 years by country, region, and globally.Methods We did a pooled analysis of cross-sectional survey data that were collected through random sampling with a sample size of at least 100 individuals, were representative of a national or defined subnational population, and reported prevalence of of insufficient physical activity by sex in adolescents. Prevalence had to be reported for at least three of the years of age within the 10-19-year age range. We estimated the prevalence of insufficient physical activity in school-going adolescents aged 11-17 years (combined and by sex) for individual countries, for four World Bank income groups, nine regions, and globally for the years 2001-16. To derive a standard definition of insufficient physical activity and to adjust for urban-only survey coverage, we used regression models. We estimated time trends using multilevel mixed-effects modelling.Findings We used data from 298 school-based surveys from 146 countries, territories, and areas including 1.6 million students aged 11-17 years. Globally, in 2016, 81-0% (95% uncertainty interval 77-8-87.7) of students aged 11-17 years were insufficiently physically active (77.6% [76-1-80.4] of boys and 84.7% [83.0-88-21 of girls). Although prevalence of insufficient physical activity significantly decreased between 2001 and 2016 for boys (from 80.1% [78.3-81-61 in 2001), there was no significant change for girls (from 85.1% [83.1-88.0] in 2001). There was no clear pattern according to country income group: insufficient activity prevalence in 2016 was 84.9% (82.6-88-2) in low-income countries, 79.3% (77.2-87.5) in lower-middle-income countries, 83.9% (79.5-89.2) in upper-middle-income countries, and 79.4% (74.0-86.2) in high-income countries. The region with the highest prevalence of insufficient activity in 2016 was high-income Asia Pacific for both boys (89.0%, 62.8-92.2) and girls (95.6%, 73.7-97.9). The regions with the lowest prevalence were high-income western countries for boys (72.1%, 71.1-73-6), and south Asia for girls (77.5%, 72-8-89.3). In 2016,27 countries had a prevalence of insufficient activity of 90% or more for girls, whereas this was the case for two countries for boys.Interpretation The majority of adolescents do not meet current physical activity guidelines. Urgent scaling up of implementation of known effective policies and programmes is needed to increase activity in adolescents. Investment and leadership at all levels to intervene on the multiple causes and inequities that might perpetuate the low participation in physical activity and sex differences, as well as engagement of youth themselves, will be vital to strengthen the opportunities for physical activity in all communities. Such action will improve the health of this and future young generations and support achieving the 2030 Sustainable Development Goals. Copyright (C) 2019 World Health Organization; licensee Elsevier.
