Is cesarean section delivery associated with autism spectrum disorder?

Area of Science:

• Medical Research
• Pediatrics
• Neurodevelopmental Disorders

Background:

• Autism spectrum disorder (ASD) is a complex neurodevelopmental condition.
• Understanding potential environmental risk factors for ASD is crucial for early intervention.
• Cesarean section (C-section) is a common birth procedure with potential impacts on infant health.

Purpose of the Study:

• To investigate the potential correlation between birth by cesarean section and the incidence of autism spectrum disorder (ASD).
• To quantify the association between C-section delivery and ASD risk.

Main Methods:

• A case-control study was conducted in Saudi Arabia in 2016.
• Data included 87 children with ASD (cases) and 174 controls.
• Logistic regression analysis was used to determine odds ratios (ORs).

Main Results:

• Approximately 39% of children with ASD were born via C-section, compared to 21% in the control group.
• An adjusted odds ratio of 2.9 (95% CI: 1.57-5.35) indicated a significantly higher risk of ASD following C-section delivery.
• The findings support a positive association between C-section birth and ASD.

Conclusions:

• A significant association exists between delivery by cesarean section and autism spectrum disorder.
• The study supports findings from previous research on this topic.
• Preventive measures to avoid non-medically indicated cesarean sections are recommended.
