One in Four Teens Worldwide Report No Active Days in a Week, WHO Warns as Activity Stalls Since 2010

GENEVA — One in four teenagers worldwide reported not a single physically active day in the previous week, according to new global estimates from the World Health Organization (WHO) released on Wednesday, November 4, 2026 — a finding the agency presents as evidence that adolescent activity has barely moved in 15 years.

The estimates, published in The Lancet Global Health, draw on 389 population-based surveys from 140 countries and territories covering more than 3.2 million adolescents aged 11 to 17. An "active day" in the study means a day with at least 60 minutes of moderate-to-vigorous physical activity — brisk walking, cycling, playing sports, or any movement that raises the heart rate. By that measure, 25 percent of adolescents reported zero active days in the previous week, a figure the WHO extrapolates to around 240 million young people.

On average, adolescents reported being active for just 2.7 days a week, and only 14 percent said they were active on all seven days — the level that matches the WHO recommendation that adolescents average at least 60 minutes of moderate-to-vigorous activity every day. The WHO warns that physical inactivity is a major risk factor for heart disease, type 2 diabetes, and some cancers, and that habits formed in adolescence tend to carry into adult life.

What Happened

The study, titled "National, regional, and global trends in adolescent physical activity from 2010 to 2025," is the first major global update of adolescent activity estimates since 2016, according to the WHO's media schedule for the week. Its headline message is stagnation: global activity levels among adolescents have remained virtually unchanged since 2010, despite a global target set in 2018 to achieve a 15 percent relative reduction in physical inactivity by 2030. On the current trajectory, the WHO says, no country is on track to meet that target.

The gender gap is persistent. Some 28 percent of adolescent girls reported no active days in the previous week, compared with 22 percent of boys, the estimates show. Age matters too: 11-year-olds reported an average of 4.6 active days a week, while 17-year-olds reported 3.6, a pattern the researchers link to the competing demands and shrinking opportunities for play and sport as teenagers grow older.

WHO Director-General Tedros Adhanom Ghebreyesus said the world had made little progress in encouraging young people to become physically active, and that girls continued to face greater disadvantages than boys, according to reporting of the release. The study's lead author, Dr Tessa Strain of the University of Edinburgh, pointed to pronounced inequalities within countries as well: in the United Kingdom, for example, only one in six adolescents (17 percent) is active every day — 13 percent of teenage girls and 21 percent of boys — while UK teenagers average four active days a week.

Background

The WHO recommendation is long-standing: children and adolescents aged 5 to 17 should accumulate an average of at least 60 minutes of moderate-to-vigorous physical activity per day. The new analysis tests how far reality falls short of that benchmark, and where. Adolescents in wealthier regions — including Central and Eastern Europe, Central Asia, East Asia, the Pacific, and high-income Western nations — averaged four active days a week, with only 6.9 to 7.7 percent reporting no activity, well below the global average of 25 percent.

At the other end of the scale, the Philippines was grouped with Namibia and Nepal among the places where around 40 percent of adolescents reported no active days. In the Philippines, the share fell only marginally over 15 years, from 40.85 percent in 2010 to 40.32 percent in 2025, according to the WHO country data reported this week. Filipino girls were less active than boys — 42.7 percent reported no active day, compared with 38 percent of boys — and only 11 percent of girls said they were active every day, against 17 percent of boys.

Researchers caution against misreading the headline figure. Reporting "zero active days" does not mean these adolescents are completely immobile or bedridden; it means they did not reach 60 minutes of moderate-to-vigorous activity on any single day in the previous week. Short bursts of movement, light activity, and active play below that threshold are not counted in the measure, which is designed to track progress against the WHO guideline rather than to capture every step a teenager takes.

The estimates are model-based: researchers used statistical models to estimate distributions by sex, age, country, and year, drawing on surveyed places and years to inform estimates for others. Country results are published only where country survey data were included, while regional and global totals also use estimates for places without direct data — a method the authors say requires careful local interpretation.

Why It Matters

The stakes are long-term. Physical activity in adolescence supports healthy growth, bone and muscle development, mental well-being, and academic performance, and it lowers the risk of the chronic diseases that now dominate adult health burdens. When a quarter of the world's teenagers miss the activity threshold entirely in a given week, the WHO argues, the cost is measured not in one quiet week but in decades of elevated risk for heart disease, diabetes, and some cancers.

The gender gap matters for policy design. If girls are systematically less active than boys — by six percentage points on the zero-active-days measure globally, and by wider margins in some countries — then generic calls to "exercise more" are unlikely to close it. The WHO's framing points instead to the environments around teenagers: safe routes to school, school sport that welcomes girls, public spaces that feel safe after dark, and timetables that protect physical education rather than squeezing it out.

The stagnation finding also matters because it challenges a comfortable assumption: that awareness alone is moving the needle. Fifteen years of guidelines, campaigns, and school programmes have coincided, on these numbers, with virtually no global improvement. That is why the WHO is presenting the estimates alongside a call for structural changes — in schools, urban planning, and transport — rather than individual advice alone. This article reports public-health research findings and is not medical advice.

What Happens Next

The WHO is formally launching the estimates with a global webinar on Friday, November 6, 2026, where its experts will set out what countries can do to create healthier, more active futures for young people. Watch for country-level breakdowns and for the policy menu the agency recommends: daily physical education, active travel to school, safe public spaces, and sports programmes designed to keep older teenagers — especially girls — involved.

The 2030 target now looks out of reach on current trends, and the next test will be whether governments treat adolescent activity as infrastructure — streets, schools, and schedules — rather than as a personal choice. The study's own numbers suggest where to start: the sharp drop between ages 11 and 17, and the persistent gap between girls and boys, are the two trends any credible plan will have to reverse first.

FAQ

What did the WHO's new estimates find?

One in four adolescents aged 11 to 17 reported no active days in the previous week — no day with at least 60 minutes of moderate-to-vigorous activity — amounting to around 240 million young people worldwide.

How many teenagers meet the daily activity recommendation?

Only 14 percent reported being active on all seven days. On average, adolescents reported 2.7 active days a week, well short of the WHO recommendation of an average of 60 minutes of moderate-to-vigorous activity every day.

How big is the gender gap?

Globally, 28 percent of girls reported no active days, compared with 22 percent of boys. In the UK, 13 percent of teenage girls were active every day, against 21 percent of boys.

Has adolescent activity improved since 2010?

No — the study finds global levels have remained virtually unchanged since 2010, and no country is currently on track to meet the 2030 target of a 15 percent relative reduction in physical inactivity.

What counts as an "active day"?

A day with at least 60 minutes of moderate-to-vigorous physical activity, such as brisk walking, cycling, or playing sports — activity that raises the heart rate.
