BACKGROUND: Birth cohort studies in some countries have shown a link between caesarean section and asthma.
AIM: To determine if there is an association between asthma and delivery via caesarean section in Malaysian children.
METHOD: This is a case-control study involving 156 children aged 3-15 years old, in a tertiary hospital in Kuala Lumpur, Malaysia. Seventy-eight children with a confirmed diagnosis of asthma and seventy-eight age-matched controls (no history of asthma or wheezing) were enrolled. Demographic data including mode of delivery and family history of allergic disorders was obtained. Total serum immunoglobulin E (IgE) was measured and skin prick tests (SPT) to 6 common aeroallergens were performed.
RESULTS: The median age of the patients was 8 years old. One hundred and three (66%) children were delivered via normal vaginal delivery, 8 (5.1%) via assisted vaginal delivery and 45 children (28.9%) via caesarean section. Delivery via caesarean section was not significantly associated with asthma (OR = 1.21 [95% CI 0.60-2.41], p = 0.596). Children delivered via caesarean section did not have higher IgE levels nor were they more sensitized to aeroallergens. Multiple logistic regression showed that asthma was significantly associated with a positive family history of atopy (OR = 13.8 [95% CI 5.96, 32.1], p < 0.001). Introduction of semi-solid food after 6 months old had a protective effect against asthma (OR = 0.97 [95% CI 0.94, 0.99], p = 0.034).
CONCLUSION: Childhood asthma in Malaysian children was not associated with delivery by caesarean section.
