The study, published in The Lancet Child & Adolescent Health journal and produced by researchers from the World Health Organization (WHO), finds that more than 80% of school-going adolescents globally did not meet current recommendations of at least one hour of physical activity per day – including 85% of girls and 78% of boys.

这项研究基于160万名11至17岁学生的数据。
The study – which is based on data reported by 1.6 million 11 to 17-year-old students – finds that across all 146 countries studied between 2001-2016 girls were less active than boys in all but four (Tonga, Samoa, Afghanistan and Zambia).
The difference in the proportion of boys and girls meeting the recommendations was greater than 10 percentage points in almost one in three countries in 2016 (29%, 43 of 146 countries), with the biggest gaps seen in the United States of America and Ireland (more than 15 percentage points).
Most countries in the study (73%, 107 of 146) saw this gender gapwiden between 2001-2016.
