Reuters: Babies born by Caesarean section are more likely to develop asthma than children delivered naturally, Swiss researchers said on Tuesday.
There has been conflicting evidence on the link between asthma and C-sections but the researchers said the number of children involved in their study and a long monitoring period strengthened their results.
The findings also underscore the potential risks of elective C-sections as more women in Western countries choose to avoid a natural birth, the researchers said in the medical journal, Thorax.
"The increased rate of Caesarean section is partly due to maternal demand without medical reason," Caroline Roduit of Kinderspital Zurich medical institution and colleagues wrote.
"In this situation the mother should be informed of the risk of asthma for her child, especially when the parents have a history of allergy or asthma."
Asthma, which affects more than 300 million people worldwide, is the most common pediatric chronic illness. Symptoms include wheezing, shortness of breath, coughing and chest tightness.
