Forceps birth delivery, allergic sensitisation, and asthma: a population-based cohort study
Clinical & Experimental Allergy, 07/03/2012
Hancox RJ et al. – Delivery with forceps assistance is associated with an increased risk of atopy and asthma, but the associations were weaker after adjustment for confounding factors. The previously reported association between caesarean birth and atopic disease may be due to confounding rather than altered exposure to maternal flora, although other factors associated with a difficult labour cannot be ruled out.
