Kids whose moms smoked during pregnancy & early childhood more likely to smoke as adults

Tags: university of arizona

[Source: ScienceDaily] - Children of mothers who smoked during pregnancy and their early childhood years may be predisposed to take up smoking as teens and young adults, compounding the physical damage they sustained from the smoke exposure.

"It is well-known that maternal smoking influences a developing fetus in myriad ways, contributing to low birth weight, premature birth and a host of other health problems after birth," said Roni Grad, M.D., associate professor of clinical pediatrics at the University of Arizona College of Medicine. "Previous studies have suggested that maternal smoking during pregnancy may increase the risk of the offspring becoming regular smokers as adults, but the impact of postnatal cigarette smoke exposure was hard to differentiate from prenatal exposure."

The study results will be presented on May 19, at the American Thoracic Society's 105th International Conference in San Diego.
