The increasing rates of Caesarean sections throughout the world is preoccupant, and a good understanding of which groups of women contribute the most to the CS rate represents an important question in public health. Therefore, we sought to report the CS rate according to the Robson's classification system in the Quebec population.We performed a secondary analysis of the QUARISMA database, including all deliveries after 24 weeks' gestation from 32 maternity wards in the province of Quebec between 2008 and 2011 (n = 184 952 deliveries). CS rates were reported according to the modified Robson criteria from The Society of Obstetricians and Gynaecologists of Canada with the relative contribution to the total number of CSs.We observed a global CS rate of 22.9%. Women with previous CS and a fetus in cephalic presentation at term accounted for 35% of all Caesarean deliveries. Nulliparous women with cephalic presentation at term accounted for 30% of all CSs. Among nulliparous women with cephalic presentation, women with spontaneous labour contributed to 12% of all CSs, whereas women with an induction of labour contributed to 16% of all CSs. Non-cephalic fetal presentation accounted for 19% of all CSs. Other indications accounted for the remaining 16% of CSs.Most CSs are performed for multiparous women with previous CS; nulliparous women with a cephalic presentation at term, especially those undergoing labour induction; and non-cephalic fetal presentation.
