Antibiotics in pregnancy? Higher risk of asthma in a child

According to Danish researchers, mothers who have taken antibiotics during pregnancy are more likely to develop asthma. They are supposed to affect the growth of bacteria responsible for immunity or the development of asthma itself. The study was conducted on 30,000 children born between 1993 and 2007. Scientists watched the little ones for five years. 1/4 of the children were under the influence of antibiotics during pregnancy. 3% of them went to the hospital because of breathing problems and were diagnosed with asthma.

Considering other factors, the researchers noted that children exposed to antibiotics during pregnancy were 17% more likely to develop asthma than children of mothers who did not take antibiotics during pregnancy.

Scientists, however, do not rule out that the development of asthma may have been affected by a disease that was supposed to be fought by the mother's antibiotics.
