Total screen time, as an indicator of sedentary behaviour, showed significant association with overweight and obesity. Total screen time increased significantly by age (higher in school children than in pre-school children) and showed large variation between countries.
According to the present data the recommendation of <1 hour/day screen time for kindergarten children and <2 hours/day screen time for school children seems to be reasonable.
