Aim: To evaluate the association between caesarean section and risk of developing asthma.

Method: 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.

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