Children who are given antibiotics before they are 1 year old run a higher risk of developing asthma.
Canadian researchers analyzed seven studies involving more than 12,000 youngsters, and found that those who were given antibiotics early on were almost three times as likely to develop asthma.
Another study found that multiple exposure to antibiotics increased the risk even more, by 16 percent for every additional course of antibiotics given.
Currently, children are often prescribed antibiotics for respiratory and ear infections, even though many such infections are viral in origin and therefore unaffected by antibiotics. The rate of Canadian children who develop asthma is double what it was two decades ago.
