A study published today by a CHEO colleague Dr. Tremblay, in The Lancet Child and Adolescent Health, involving data for more than 577,000 adolescents (ages 13 to 15) from 42 North American and European countries, finds that: 1) increased physical activity is clearly associated with better mental wellbeing and 2) more than 2 hours per day of recreational screen time, is bad for mental wellbeing. It is the first study to show such clear relationships in a large multi-country sample.
