Overall, infants who were exposed to at least one antibiotic were twice as likely as unexposed infants to develop asthma during childhood. The researchers also analyzed data from five studies including 27,167 children looking at antibiotic doses. It found that for each extra course of antibiotics during the first year of life a child was 1.16 times more likely to develop asthma.
