More evidence parents should monitor kids' media diet

NEW YORK: How parents monitor the television and videogame habits of their children is tied to the kids' performance in school, their relationships with peers and their weight, according to a new study. 

"It's a fairly small effect, but what's interesting about this study is because we tracked these children over time we see these effects build," lead author Douglas Gentile told Reuters Health. He is a psychologist at Iowa State University in Ames.
