The development of physical aggression in children as they age is being studied here in this study.

‘Some factors such as 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 were also found to influence the development of physical aggression.’

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.
