Study examines development of physical aggression in children as they age

December 28, 2018

BottomLine: Children can exhibit physical aggression when they are very young but that behavior typically declines before and during elementary school. However, a small proportion of children have atypically high physical aggression problems into adolescence, which may put them at increased risk for violent crime, social maladjustment, and alcohol and drug abuse. This observational study of 2,223 boys and girls used information from mothers, teachers and the children to trace the development of physical aggression problems from infancy to adolescence. The analysis suggests the frequency of physical aggression increased from age 1½ to 3½ and then decreased until age 13. Trajectories for the development of physical aggression differed for boys and girls, and several risk factors were identified, including family characteristics when the child was an infant such as having parents with lower education and higher depression, lower socioeconomic status and a higher number of siblings. Interventions during pregnancy and early childhood may help to prevent high physical aggression in children in high-risk families.
