Kids can show physical aggression real early say before and during elementary school, finds a new study. The results of this study are published in the JAMA Network Open.
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.
Interventions during pregnancy and early childhood may help to prevent high physical aggression in children in high-risk families.
