title: [It is uncertain if caesarean section is a risk factor to the development of asthma].
abstract: In Denmark the prevalence of both asthma and caesarean section has increased during the last 20 years. This review investigates the coherence between caesarean section and the development of asthma. Twelve epidemiological articles about children over three years were included. Eight of 12 studies discovered no association between caesarean section and asthma. There is no difference in the quality of the studies. We can conclude that it is uncertain if caesarean section is a risk factor to the development of asthma, but it cannot be eliminated that asthma is one of many consequences of caesarean section.
