title: The rise in caesarean birth rate in Sagamu, Nigeria: reflection of changes in obstetric practice.
abstract: A retrospective and comparative study of women delivered by caesarean section over two different 3-year periods was conducted at Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria. The caesarean section rate (CSR) increased from 10.3% in 1989-1991 to 23.1% in 2000-2003. The most frequent indication in both periods was different: prolonged/obstructed labour (20.0%) in 1989-1991 and antepartum haemorrhage (14.9%) in 2000-2003. Malpresentation, antepartum haemorrhage and pre-eclampsia/eclampsia were responsible for 51.7% of the difference in the CSR recorded between both periods. The CSR rose from 13.3% to 25.0% while the instrumental vaginal delivery (IVD) rate decreased significantly by 11.4% among the nulliparous women between the periods. Increase in CSR can be attributed mainly to reduction in IVD rate and alteration in the management of labour complications and induction policy. Strategies to reduce the CSR should cut across all indications and focus on encouraging instrumental vaginal deliveries, especially among nulliparous women.
