Smoking in pregnancy increases chance of problem kids

Smoking during pregnancy significantly increases the risk of having a child with behavioural problems.

Researchers from the Universities of York, Hull and Illinois were looking at 14,000 mother/child pairs in the Millenium Cohort Study.

In the Journal of Epidemiology and Community Health, the researchers say the problems can be evident in children as young as three years old.

They believe smoking in pregnancy may damage the developing structure of the baby’s brain.

The results also show problem conduct in both boys and girls, but hyperactivity and attention deficit affect mainly boys.

Light smokers were 44% more likely to have problem boys.  Heavy smokers were 80% more likely to have problem boys.
