A study of 744 low-income women published in the American Journal of Public Health shows that women who continue to smoke during pregnancy are more likely to suffer from psychiatric disorders such as anxiety disorder, attention deficit hyperactivity disorder or substance addiction.
Women who had smoked prior to becoming pregnant and then quit were twice as likely to suffer from a mental illness than women who had not smoked. However, women who smoked before pregnancy and did not quit were 2.5 times as likely, with 25 percent of persistent smokers having been diagnosed with a disorder. Those with a mental illness also smoked an average of 9.2 cigarettes per day compared with 6.5 for those without.
These findings point out a need to address psychiatric disorders in pregnancy smoking cessation programs, researchers say.
