Physical inactivity is the fourth leading cause of death worldwide. It’s also associated with chronic illness and disability.

Recent research estimates that the world could see close to half a billion new cases of major chronic diseases by 2030 if people don’t get more active. Regular physical activity helps to prevent and manage many chronic diseases. Popular ways to be physically active include walking, cycling, and playing sports.

The World Health Organisation (WHO) recommends that children and adolescents (5-17 years old) get an average of at least 60 minutes per day of moderate to vigorous intensity physical activity.

This should incorporate vigorous aerobic activities, as well as those that strengthen muscle and bone, at least three days a week. It’s also recommended that children spend no more than two hours a day on recreational screen time. These recommendations aim to improve children’s physical and mental health, as well as cognitive outcomes.

Before the COVID-19 pandemic, physical activity among children and adolescents was already below the recommended levels. In 2016, 81 per cent of adolescents around the world aged 11-17 were considered physically inactive. Girls were less active than boys.

The pandemic has made matters worse. Physical inactivity in children and adolescents has become a global public health priority. It is now included in global action plans.

For example, using 2016 as baseline, the WHO through its Global Action Plan on Physical Activity targeted a 15 percentage point reduction in prevalence of physical inactivity among adolescents by 2030.

This call to action also implored other international organisations and governments to help track progress in physical activity promotion among children and adolescents.
