Time trends in caesarean section rates and associations with perinatal and neonatal health: a population-based cohort study of 1 153 789 births in Norway.

ABSTRACT:

Objectives

To study caesarean section (CS) rates and associations with perinatal and neonatal health in Norway during 1999-2018.

Methods

CS, intrapartum, perinatal and neonatal mortality rates expressed as percentages (%) or per mille (‰) with 95% CIs.

Primary and secondary outcome measures

CS rates in the Robson Ten-Group Classification System; intrapartum, perinatal and neonatal mortality rates.

Results

The overall CS rate increased from 12.9% in 1999 to 16.7% in 2008 (p<0.001), and then reduced to 15.8% in 2018 (p<0.001). The largest reductions were observed in Robson groups 2 and 4. In Robson group 2, the
