To explore the secular trends of cesarean delivery and cesarean delivery on maternal request (CDMR) among primiparous women with singleton pregnancy in Southern and Northern China. The Perinatal Healthcare Surveillance System was established in 26 counties/cities of 3 Chinese provinces since 1993. A total of 1 317 774 primiparous women with singleton pregnancy were monitored through the system during the 1993 - 2010 period. Chi-square tests were performed to assess the linear trends in the prevalence of cesarean delivery and CDMR. During the 18-year period, 496 054 cesarean deliveries and 129 219 CDMRs were identified. The prevalence rates of cesarean delivery and CDMR were 37.6% and 10.0% respectively. CDMR accounted for 26.0% of all cesarean births. The prevalence of cesarean delivery increased from 29.4% during the 1993 - 1995 period to 58.7% during the 2006 - 2010 in Southern urban area, from 18.2% to 58.3% in Southern rural area and from 4.3% to 49.5% in Northern rural area. The prevalence of CDMR increa
