Quarter of adolescents report no weekly physical activity

In 2025, one in four adolescents worldwide—about 240 million young people—did not engage in any physical activity during the week, according to a new global study published in The Lancet Global Health. The study, which analyzed 389 surveys covering 3.2 million adolescents aged 11 to 17 across 140 countries, found the global average of active days remained at 2.7 per week, unchanged since 2010. Only 14 percent were active every day, and boys averaged three active days per week compared with 2.4 for girls. No region is on track to meet the WHO target of a 15 percent reduction in adolescent inactivity by 2030.
