Smoking during pregnancy tied to kids’ asthma | Reuters

Yet another reason to quit the habit! -

Many studies have found that secondhand smoke may worsen kids’ asthma symptoms, or possibly raise their risk of developing the lung disease in the first place.

But it’s been less clear if smoking during pregnancy is linked to asthma. Most studies have not been able to tease out the possible effects from those of secondhand smoke after birth.

The new study, however, had a large enough group of kids who were exposed to smoking in the womb, but not after birth, according to the researchers.

And it found that those children were two-thirds more likely to have asthma by age six, versus kids whose moms did not smoke during pregnancy. Even smoking during the first trimester alone was linked to higher asthma risk.

The findings cannot prove that prenatal smoking was the cause.

But there are already plenty of reasons for women who are planning to have a baby to quit smoking, said Anna Bergstrom, a researcher at the Karolinska Institute in Stockholm who worked on the study.

Smoking during pregnancy is linked to increased risks of miscarriage, low birth weight, certain birth defects and other pregnancy complications.

“I think that our study provides yet another good reason to quit smoking,” Bergstrom said in an email.

The findings, published online in the American Journal of Respiratory and Critical Care Medicine, come from data on 21,600 European children.
