Study: Weekday TV viewing harms class performance

Carla Johnson:

Parents now have science to back them up when they say, “Turn off the TV. It’s a school night.”
Middle school students who watch TV or play video games during the week do worse in school, a new study finds, but weekend viewing and gaming does not affect school performance much.
“On weekdays, the more they watched, the worse they did,” said study co-author Dr. Iman Sharif of Children’s Hospital at Montefiore in the Bronx. “They could watch a lot on weekends, and it didn’t seem to correlate with doing worse in school.”
Children whose parents allowed them to watch R-rated movies also did worse in class, and for boys, that effect was especially strong. The findings are based on a survey of 4,500 students in 15 New Hampshire and Vermont middle schools. The study appears in the October issue of Pediatrics.
