Effects of smoking during pregnancy tested


Infants whose mothers smoked during pregnancy have significantly less lung capacity than infants of non-smoking moms, a new study from Harvard University Medical School shows.

The damage maternal smoking does to a newborn's lungs also maybe related to increased cases of asthma, respiratory infections and even lung disease later in life, according to Dr. John P. Hanrahan.

Among 80 infants two weeks to six weeks old, lung-function tests of those whose mothers smoked during pregnancy were as much as 50 percent below normal, Dr. Hanrahan reported.
