One in four adolescents worldwide are not getting enough physical activity, raising concerns about the long-term health of millions of young people, according to new global estimates released by the World Health Organization (WHO).
The findings show that around 240 million adolescents aged 11 to 17 reported no day in the previous week with at least 60 minutes of moderate-to-vigorous physical activity. On average, teenagers were physically active for just 2.7 days per week, while only 14% met the recommended daily activity level throughout all seven days.
The study, titled A Generation Missing Out, analysed 389 population-based surveys involving more than 3.2 million adolescents across 140 countries and territories. It also found that global activity levels have remained almost unchanged since 2010.
A significant gender gap was identified. Around 28% of girls reported no physically active days during the previous week, compared with 22% of boys. Only 11% of girls were active every day, compared with 17% of boys.
Health experts warn that physical inactivity during adolescence can increase the risk of heart disease, type 2 diabetes and certain cancers. Regular movement also supports mental health, healthy growth, social development and learning.
The report highlights several barriers, including a lack of safe public spaces, limited sports facilities, transport challenges, social restrictions and safety concerns, particularly for girls.
WHO is urging governments to make physical activity easier and safer through better school sports programmes, parks, walking and cycling routes, and accessible recreational facilities. Experts say encouraging teenagers to exercise is not enough; communities must also provide safe environments where young people can stay active.
