Screen time

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.
