Nicotine is known to cross the placenta and enter the fetal bloodstream and can lead to development problems in babies.
The more you are exposed to nicotine during pregnancy, the more are the chances for your baby to develop schizophrenia, revealed a new study.The Finland study published in the American Journal of Psychiatry analyzed data on 1,000 schizophrenia patients and compared their birth and health records with those of non-affected 'control' individuals.
Nicotine is known to cross the placenta and enter the fetal bloodstream and can lead to development problems in babies. Therefore, blood tests to identify a nicotine marker called as cotinine was carried out among the mothers during first and second trimester of pregnancy.
The test results showed that 20% of mothers of schizophrenia patients had smoked heavily during pregnancy than 14.7 % of mothers of controls.
The study concluded that nicotine exposure during pregnancy increased babies risk of developing schizophrenia by 38%.
Senior researcher Professor Alan Brown, from the University of Columbia, New York, said, “To our knowledge, this is the first biomarker-based study to show a relationship between fetal nicotine exposure and schizophrenia.”
