Hyperactivity leads to physical aggression
Hyperactive young boys who don't like to share are at high risk of persistent physical aggression, say researchers from Carnegie Mellon University in Pittsburgh and the University of Montreal in Canada.
Researchers studied characteristics that lead to
aggressive behavior in more than 1,000 boys between the ages of 6 and
15 years. They studied behaviors such as physical aggression, opposition (defined as unwilling to share materials, irritable, disobedient, blames others and inconsiderate), hyperactivity, inattention, and anxieties.
Researchers found boys in kindergarten who showed high levels of hyperactivity and opposition had the highest risk of being physically aggressive as they aged. Authors of the study write, "Individually, these risk factors increased the odds of ... high physical aggression by about a factor of three. In combination, the increase is more than nine-fold."
Researchers say high aggression was also linked to low education among the mothers of these boys and whether or not these boys were born to teen mothers. They say these high-risk children could significantly benefit from early intervention adding that they can be
identified in kindergarten by watching for hyperactivity levels, high opposition, teen motherhood, and low education among mothers.
