A new study has show just how important it is for pregnant women to stay away from even second-hand smoke by finding that it can cause serious psychological problems in their children.
The study was conducted by a team of researchers from the University of Washington by psychologists Lisa Gatzke-Kopp and Theodore Beauchaine.
The researchers found that such kids have more symptoms of serious psychological problems compared to the offspring of women who had no prenatal exposure to smoke.
The study also provides the first evidence linking mothers' second-hand smoke exposure while pregnant to their children's attention deficit hyperactivity disorder (ADHD) and conduct disorder.
Psychologists call these behaviours externalising psychopathology and their symptoms include aggressive behaviour, ADHD, defiance and conduct disorder, which encompasses truancy, fighting, school failure, breaking rules, substance use, stealing and destruction of property.
As a part of their study, Gatzke-Kopp and Beauchaine compared patterns psychopathology among three groups of 7- to 15-year-old children, all of whom had significant behavioral and/or emotional problems.
One group experienced no prenatal smoke exposure. The second was made up of children whose mothers smoked during the final two trimesters of pregnancy. The third consisted of children whose mothers were exposed to second-hand smoke at work or in the home in the last two trimesters during pregnancy.
A total of 171 children, primarily boys, and 133 women participated in the project.
The UW researchers found that those children whose mothers had been exposed to tobacco smoke either by smoking or by being around smokers when they were pregnant had more symptoms of ADHD and conduct disorder than children whose mothers spent their pregnancies in a smoke-free environment. However, they did not show more symptoms of emotionPage: 1 2 Related medicine news :1
