According to a new study, second-hand smoke exposure early in the childhood makes kids aggressive. Exposure to this smoke at early childhood is particularly dangerous, as it may make children antisocial as adults. The findings were regardless of whether their mothers smoked while they were pregnant or their parents had a history of anti-social behaviour.
The researchers at the Linda Pagani of the University of Montreal looked at data that was collected about 2,055 kids from their birth until ten years of age, including parent reports about secondhand smoke exposure and from teachers and children themselves about classroom behaviour. It was noted that those who have been exposed to second-hand smoke were much more likely to report themselves as being more aggressive by time they finished fourth grade.
Although, the study found no direct causal other than statistical correlation suggesting that second-hand smoke exposure does forecast deviant behaviour in later childhood.
The study findings were published in the Journal of Epidemiology and Community Health.
