A new study finds no link between caesarean section and autism.
The new study denies the previous study that associated C-sections with autism.
Researchers from the Irish Center for Fetal and Neonatal Translational Research examined data on C-sections and autism among 2.7 million children born in Sweden over 1982-2010. They found that babies born through C-section were 20 percent more likely to develop autism.
Now, when the researchers re-examined the modes of delivery of 13,411 sibling pairs, only 1 child was found to have autism. Hence, they concluded that autism is caused by unknown genetic and environmental factors; it is not related with the type of delivery.
Initially, the researchers had concluded that certain factors such as changes in microbiota and different types of anaesthesia associated with C-sections can increase the autism risk.
Ali Khashan, study author of the Irish Center for Fetal and Neonatal Translational Research in Cork, Ireland said that hypothetical mechanisms play no role in the association between caesarean section and ASD.
“Caesarean section rates are increasing worldwide and more research is needed to help us better understand the benefits and risks. This would help women and clinicians make an informed decision on the most suitable mode of delivery (for them)”, added Khashan.
