Australian researchers looked at more than 170,000 pregnant women and found that those with asthma who also were smokers had the highest rate of premature birth compared to women who neither smoked nor had asthma. The chances of bleeding from the birth canal prior to labor, urinary tract infections, low birth weight and premature membrane ruptures were also tied to prenatal asthma and smoking, according to the study published in the European Respiratory Journal.
