Insights

Cesarean section delivery may increase the risk of Kawasaki disease in infants. This study found a higher risk of Kawasaki disease in children born via Cesarean section.

Area of Science:

  • Pediatrics
  • Immunology
  • Epidemiology

Background:

  • Cesarean section delivery is linked to childhood microbiota disruption and immune dysregulation.
  • The association between Cesarean section and Kawasaki disease risk is not well-established.

Purpose of the Study:

  • To investigate the potential association between Cesarean section delivery and the incidence of Kawasaki disease.

Main Methods:

  • A birth cohort of 15,796 mother-infant pairs in Taiwan was analyzed.
  • Poisson regression and propensity score matching were used to assess associations.
  • Febrile convulsion, trauma, and accidents served as negative control outcomes.

Main Results:

  • Cesarean section delivery was associated with an increased risk of Kawasaki disease (aRR: 2.22, 95% CI: 1.14-4.34).
  • This association persisted in the propensity score-matched subpopulation (aRR: 2.29, 95% CI: 1.14-4.68).
  • No association was found between Cesarean section and control outcomes.

Conclusions:

  • Cesarean section delivery may be associated with a higher risk of Kawasaki disease in infants aged six to eighteen months.
  • The findings suggest a potential link between birth mode and Kawasaki disease development.
