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.”
