Parents who are concerned about having a child with asthma may want to consider which month they conceive, a new study suggests.

Due to winter virus exposure, babies born in the fall have higher asthma risk.

Children born in the fall months, before the height of cold and flu season, may be more likely to develop childhood asthma than babies born at other times, according to a new study published in the American Journal of Respiratory and Critical Care Medicine.

A team of researchers led by Dr. Tina Hartert, director of the Center for Asthma Research and Environmental Health at Vanderbilt University, examined records for more than 95,000 children and their mothers in Tennessee.

Is Asthma Drug Linked to Suicidal Behavior?

They found that risk for childhood asthma was higher for babies who suffered from a respiratory tract infection early in life -- and babies born in the fall months seemed particularly at risk for contracting respiratory viral infections.
