Screen time is bad for active kids too

摘要

Children who watch TV or play computer games for 2 hours or more a day are more likely than others to concentrate poorly, behave badly and have social problems - even if they exercise. Angie Page at the University of Bristol, UK, wondered whether it matters if kids spend a lot of time in front of a screen if they are also physically active. To find out, her team measured 1013 children's exercise levels and TV and computer habits for a week.
