Children with aggressive behavior in the first years of life have higher risk of behavioral problems in the future, such as juvenile delinquency, crime and violence as adults. There are several factors that might contribute to the development of aggressive behavior in children, including the level of discipline demanded by parents, environment and safety of the neighborhood as well as media exposure. A survey published recently by the Archives of Pediatrics & Adolescent Medicine confirms this influence of the media to show that children under 3 years of age exposed to more TV are more likely to develop aggressive behavior. And that was not the direct exposure of children to TV. The time that the TV is turned on in the homes was also a factor associated with the aggressiveness of children attend independent or not.

The poll surveyed over three thousand American women to the level of television exposure for their children, since the time of birth, the first and third years of life. A rating scale of aggression has also been applied to three years old. About two thirds of mothers reported that their children watched television three years more than two hours a day, and many admitted that machine had a role of babysitter at home. The average time that the TV was blaring in the homes studied was 5.2 hours per day.

And that exposure to TV increases the chances of aggressive behavior in this age group? One explanation is that more TV time creates more chance of children watching inappropriate content for their age. Moreover, the time on TV, not only children but also adults, competes with the time from other activities, such as the interaction time between parents and children, reading stories, playing and sleeping.

In this study, the average exposure of children to TV was 3 hours per day above the current recommendation that they should not be more than two hours in front of the video (TV, computer), and in the case of children under two years, these should not be exposed to video in any way. This groundbreaking study is to reveal that excessive TV at home has negative repercussions on the child's life even though she is not who is in front of the television.
