Recent studies on asthma in children from from MoBa (Norwegian Mother and Child Cohort Study) suggest that babies delivered by way of caesarean section possess a higher risk of developing asthma symptoms before they turn three years of age. This situation was predominantly noticeable in young children absent a genetic or hereditary trend to asthma and allergies.
Figures from over 37,000 trialists throughout the MoBa survey were chosen to examine any connections between the delivery procedures of babies and the proliferation of lower respiratory tract infections, wheezing and asthma in the initial three years of a childs life.
Infants birthed by deliberate or emergency medical caesarean section were compared against babies born vaginally and the findings demonstrate that kids born by caesarean section have a higher chance of experiencing asthma symptoms in their first three years. However, no elevated risk of recurrent lower respiratory tract infections or wheezing were observed.
The children born by caesarean of mothers without allergies who participated in the study showed higher risk of asthma than those of mothers who have allergies.
“It is unlikely that a caesarean delivery itself would cause an increased risk of asthma, rather that children delivered this way may have an underlying vulnerability,”
Maria Magnus, researcher in the Department of Chronic Diseases at Norwegian Institute of Public Health.
The higher likelihood of asthma in these babies could be resulting from an adjusted bacterial flora within the intestine that affects development of the immune system. Babies born by caesarean section frequently display a higher likelihood of severe respiratory issues during the first couple months after birth.
