Compared to smokers, people who are around smokers or commonly known as secondhand smoke has long been known to be negatively affected is greater than the smokers themselves, especially if the second-hand smoke is pregnant. A new study has revealed that exposure to smoking in women who is pregnant may lead to the emergence of the risk of behavioral disorders in the child.
In detail, this study showed that children who had in utero exposure to smoking at least 30 minutes a day two times higher risk of having attention disorders tend to be aggressive and when he reached five years than women who are not affected by exposure to cigarettes.
These findings obtained after a team of researchers led by Jianghong Liu of the University of Pennsylvania School of Nursing 600 couples observe the conditions of mothers and children in Jintan, China. Researchers asked mothers to recall how often they are exposed to smoking during pregnancy. Researchers also observed behavioral disorders experienced by children when aged 5-6 years using behavior scale.
"37 Percent of mothers in the study published in the journal Neurotoxicology reported exposure to secondhand smoke during pregnancy. Yet 25 percent of them have children who have attention disorders and tend to be aggressive, while children whose mothers were not exposed to cigarette but have behavioral disorders only 16 percent , "Liu said, as reported by MyHealthNewsDaily, Sunday (31/03/2013).
Unfortunately, although the researchers considered factors that can influence the behavior disorders in children such as a history of psychological disorders in parents, maternal age, sex of the baby until the levels of lead found in the blood of the baby, they can not determine if there are other factors that affect findings.
Researchers also do not collect information such as whether the baby is born premature or low birth weight and whether or not caused by exposure to smoking during pregnancy.
It's just a new study from Canada revealed that the cigarettes from China are known to contain heavy metals such as lead, cadmium and arsenic are three times more than cigarettes manufactured in Canada. Though all three metals were identical to behavioral disorders in people who consume cigarettes that contain three or passive smokers around them.
In other words, it could be kids in China more at risk of conduct disorder than children in other parts of the world because the content of cigarettes produced in the country.
