Preschoolers who watched such fare more likely to act out at 7, 10, study found

Preschool boys exposed to violent television -- even cartoons -- are more likely to become aggressive later in life, researchers warn.

Their findings don't definitively prove that TV makes children act up, and girls seemed entirely unaffected by violent fare, according to the researchers. But the link does appear solid in the case of boys, said study lead author Dr. Dimitri Christakis, professor of pediatrics at the University of Washington, Seattle.

"If parents are really interested in their kids' behavior, they have to be very selective and thoughtful about what their children watch," Christakis said. "That requires a fair amount of education on their part. They can't think, 'It's a cartoon, and it's harmless.' They have to be more thoughtful."

A number of studies have linked violence on television to aggression among children, but the new research is unusual, because it looked at the effects of television watching on kids between the ages of 2 and 5, Christakis said.
