A woman uses her smart phone as apps are shown on an iPad in Mississauga, Ont., on November 13, 2017. A new study finds teens who spend more time watching TV, talking on mobile phones and using social media are more likely to drink more sugared or caffeinated drinks than others. McMaster University researchers examined U.S. data from 32,418 students in Grades 8 and 10 and found those who spent an additional hour per day on TV were at 32 per cent higher risk of exceeding World Health Organization recommendations for sugar.
