Although in the past many studies have linked Cesarean section births with risk of developing autism spectrum disorder, a new research – published JAMA Psychiatry – now claims its entirely bogus. The connection seemed supported by the steady rise in the rates of both cesarean sections and ASD diagnosis over the last 20 years.
However, Swedish researchers who looked at more than 2 million babies born in Sweden between 1982 and 2010 discovered that this connection is most likely to be just coincidental, and that there is no strong support to the claim that cesarean sections result in autism.
Interestingly, researchers did confirm previous studies that children born by cesarean section were 20 percent more likely to be diagnosed with ASD. But, at the same time, they also noted that the same association between cesarean births and ASD did not exist when siblings were compared with each other.
This goes on to show that the reasons are more likely to be due to genetic or environmental factors that increase the likelihood of both cesarean sections and ASD.
