Caesarean birth in women with infertility: population-based cohort study.

ABSTRACT:

Objective

Caesarean section (CS) is more common following infertility treatment (IT) but the reasons why remain unclear and confounded. The Robson 10-Group Classification System (TGCS) may further explain variation in CS rates. We assessed the association between mode of conception and CS across Robson groups.

Design

Population-based cohort study.

Setting

Ontario, Canada, in a public healthcare system.

Population

921 023 births, 2006-2014.

Methods

Modified Poisson regression produced relative risks (RR) and 95% confidence intervals, comparing the risk of CS among women with (1) subfertility without IT, (2) non-invasive IT (OI, IUI) or (3) invasive IT (IVF)-each relative to (4) spontaneous conception (SC).

Main outcome measures
