Childhood exposure to secondhand smoke could lead to aggressive and antisocial behavior
According to World Health Organization, over 40% of children worldwide are exposed to secondhand smoke. Secondhand smoke does not only lead to health risks, a research study from University of Montreal and its affiliated CHU Sainte-Justine Hospital proved that exposure to secondhand smoke in early childhood can lead to aggressive and antisocial behavior in later childhood.

The research studied the amount of household secondhand smoke exposure of 2,055 children from birth until age of ten and their classroom behavior reported from teachers and themselves by time they finished fourth grade.

It found that children continuously or intermittently exposed to secondhand smoke in early childhood, in comparison to their never exposed peers, showed an increased propensity toward physical aggression and antisocial behavior regardless of pre-birth secondhand smoke exposure and parental antisocial history.

Dr Pagani, one of the researchers, pointed out that secondhand smoke can cause low birth weight and slowed fetal brain growth. It contains high concentration of respirable toxic substances. Smoke exposure is harmful to children’s health and cause negative impact towards their neurobehavioral development.

Parents should stop smoking to provide a smoke-free environment for better physical and mental health of their children.
