Watching TV, aggressive kids linked

NEW YORK: The more television that a 3-year-old watches, the more likely he or she is to behave aggressively, according to a US study.

Just having the TV on in the background, even if the child wasn't watching it, was also linked to aggressive behavior although the relationship wasn't as strong, said the researchers.

"Parents should be smart about TV use," researcher Jennifer Manganello from the University at Albany, State University of New York, said.
