Prenatal Smoking Raises Asthma Risks
Filed in archive Asthma by ruth on May 4, 2006

At age 14, the girls were nearly twice as likely to have asthma symptomsif their mothers smoked at least 20 cigarettes a day during pregnancy. The risk was slightly greater if mothers also smoked heavily during the girls' early infancy. However, the researchers found, in utero exposure to cigarette smoking had a stronger effect than exposure after birth.
These were preliminary findings, and clearly, there is a need for further studies to interpret these observations. They do have a theory why maternal smoking did not have an impact on boys, however. Read the full article from Reuters (via YahooNews): Prenatal smoking boosts teen girls' asthma risk.
