Yes, but it has nothing to do with violence in videogames, it's because they lack a healthy outlet for physical energy, it prevents them from developing patience and prevents proper socialisation. There's nothing wrong with a video game a dozen or so times a year but nobody should be logging hours every week.
I accidentally played Night Trap when I was a little kid and now I murder teenage girls.
I don't know if these things are correlated, but they probably are.
