Children who sit for hours a day are more likely to getĀ depressionĀ at the age of 18, a study has warned.
Researchers tracked activity levels of 4,200 youngsters aged between 12 and 16 using activity trackers. Then they quizzed them on their mental health at adolescence.
For every 60 minutes a child spent on the sofa per day, their depressive symptoms at 18 rose by 10 per cent.
