Physical activity (PA) is a beneficial health behaviour. To present the worldwide, regional, and national prevalence of PA participation in adolescents. The study was based on surveys of adolescents’ population from several countries worldwide. The sample comprised 520,533 adolescents (251,788 boys, 268,745 girls), from 105 countries and regions. Most adolescents engaged in PA up to 3 times/week (57.1%). The prevalence of engaging in PA every day decreases over the age from 28.2% at age of 11-12 years (95% CI: 27.4, 29.0) to 21.2% at age of 16-17 years (95% CI: 20.3, 22.0) among boys, and from 19.4% (95% CI: 18.5, 20.2) to 11.1% (95% CI: 10.1, 12.0) among girls. For boys and girls who engaged in PA 5-6 times/day, the prevalence increases from countries with the lowest human development index to countries with the highest. Cambodia (7.3%, 95% CI: 3.8, 10.8), Philippines (7.7%, 95% CI: 5.6, 9.7), Sudan (8.8%, 95% CI: 4.7, 12.9), Timor-Leste (8.9%, 95% CI: 5.5, 12.3), and Afghanistan (10.1%, 95% CI: 6.1, 14.1) were the countries with the lowest prevalence of sufficient PA. National, regional and worldwide data on the prevalence of PA in adolescents highlights the importance of improving the global levels of PA, especially in girls.

进行体育锻炼（PA）是有益的健康行为。介绍PA在青少年中的全球性，区域性和全国性流行情况。这项研究基于对来自全球多个国家的青少年人口的调查。样本包括来自105个国家和地区的520,533名青少年（男251,788名，女268,745名）。大多数青少年每周进行PA最多3次（57.1％）。每天参与PA的患病率从11-12岁的28.2％（95％CI：27.4，29.0）降低到16-17岁的21.2％（95％CI：20.3，22.0）男生的比例从19.4％（95％CI：18.5，20.2）上升到11.1％（95％CI：10.1，12.0）。对于每天进行5-6次PA的男孩和女孩，从人类发展指数最低的国家到最高的国家，其患病率会增加。柬埔寨（7.3％，95％CI：3。8、10.8），菲律宾（7.7％，95％CI：5.6、9.7），苏丹（8.8％，95％CI：4.7、12.9），东帝汶（8.9％，95％CI：5.5、12.3）和阿富汗（10.1％，95％CI：6.1，14.1）是充足的PA患病率最低的国家。关于青少年PA患病率的国家，地区和全球数据突显了提高全球PA尤其是女童PA水平的重要性。
