Caesarean delivery and risk of developing asthma in the offspring.
OBJECTIVE
To evaluate the association between caesarean section and risk of developing asthma.


METHODS
We evaluated this association in a Danish cohort, comprising of 11,147 mothers and their babies of which 7119 mother-child pairs were included in the analyses. The mothers' reported asthma data on their children were linked to hospitalization records on mode of delivery.


RESULTS
The adjusted odds ratio for developing asthma was 1.11 (95% CI, 0.88-1.39) for caesarean sections versus vaginal births.


CONCLUSIONS
We found no evidence that children being delivered by caesarean section have an increased risk of asthma.
