Another Reason Not to Smoke During Pregnancy

A prospective study in Finland from 1983 to 1998 has found maternal cotinine levels (one of many toxic substances in cigarette smoking), after adjusting for multiple confounders, conveyed a significant excess risk (2.6 to 3.4 times higher) for schizophrenia. When psychiatric disorders were explored for maternal and paternal histories there was no significant additional risk.

PositiveTip: The evidence is clear: maternal cigarette smoking is dangerous for the physical and mental health of the child.
