New Global Data Shows One in Four Teens Misses Daily Exercise Goal

Researchers recently released data showing that a small minority of children and teenagers worldwide meet the recommended standard for daily physical activity. The new study, published in The Lancet Global Health, analyzed surveys from more than 3 million adolescents across 140 countries over a 15-year period. The World Health Organization advises that adolescents spend at least one hour a day engaging in moderate to vigorous exercise, such as a brisk walk or playing soccer.

The findings indicate that only about 14% of young people globally report getting that full hour of activity. The average adolescent in the study reported being active for fewer than three days per week. Specifically, one in four participants said they did not hit the 60-minute mark on any day during the week. The data reveals that progress has stalled, with trends remaining flat over the last decade and a half.

Fiona Bull, who heads the physical activity unit at the World Health Organization and co-authored the study, described the results as disappointing. She noted that the lack of improvement in activity levels over the past 15 years suggests that current strategies are not working. Bull stated that the data is a call to reevaluate current approaches because business as usual will not change these trends. The study highlights a clear gap between the recommended health guidelines and the actual habits of young people in schools and communities.

Gender and income levels play a major role in these disparities. Girls were less active than boys in virtually every country included in the survey. Nearly 30% of girls reported no exercise during the week, compared to 22% of boys. Only 11% of girls were active daily, while 17% of boys reported the same. The weekly average of active days was also lower for girls at 2.4 days, compared to three days for boys. Solveig Cunningham, a global health researcher at Emory University, pointed out that if a teen has a baseline of zero activity days, that pattern often carries into adulthood.

Adolescents from middle- and lower-income countries also reported lower levels of exercise than their peers in wealthier Western nations. Andrea Ramirez Varela, an epidemiologist at the University of Texas Health Science Center in Houston, explained that physical activity is often an issue of opportunity. In many lower-income regions, the environment restricts where young people can live, learn, and play. Varela noted that while rural teens in these areas often move more out of necessity, urban areas with high populations tend to have lower activity levels because many cities are not designed to be walkable.

Safety concerns and air pollution further limit outdoor activity in these urban centers. Varela observed that in many parts of Latin America, parents often consider it unsafe for children to walk alone or play independently. Additionally, screens contribute to sedentary behavior. Varela said that when kids and adolescents arrive home after school, they frequently spend the rest of the day in front of a TV or digital device. The attractive nature of the digital world keeps them stationary for long periods.

Cultural norms also influence how girls engage in physical activity. Cunningham noted that in many places, taboos around girls' physical activity emerge at puberty. She cited research from India, where mothers or grandmothers may discourage girls from spending time outside to avoid their skin darkening, which can have social implications. Cunningham added that girls are often active in less intense ways, such as doing chores. She explained that while a boy might be outside playing and a girl inside sweeping, both are active, but the types of activity are not the same.

Experts suggest that schools are a practical starting point for improving these trends. Varela stated that to make progress, policymakers must focus on the settings where kids and adolescents spend most of their time. Data shows that countries with higher levels of adolescent exercise tend to have more structured time for sport during or after the school day. Building such programs can help close the gap if sport is made accessible and affordable. Varela emphasized that not solving the problem during this stage of life will perpetuate it into adulthood, where the costs to physical and mental health become greater.
