We analyzed CD rate trend and CD contribution trend in each Robson group. Logistic regression was used to calculate the odds of CD while adjusting for confounding variables.Results The overall CD rate decreased from 49.0% in 2011 to 40.6% in 2016. In nulliparous women with singleton cephalic term pregnancy and planned CD, the CD contribution rate was reduced significantly from 29.3% in 2011 to 16.4% in 2016 (p < 0.001). In multiparous with a scarred uterus, the CD contribution rate began to increase from 3.8% in 2011 to 9.1% in 2016 (p < 0.001). Compared with delivery in 2011, delivery in 2016 was associated with a 37% (adjusted odds ratio [aOR]: 0.63; 95% confidence interval [CI]: 0.60–0.66) reduction in CD. This reduction was observed in both nulliparous women with singleton cephalic term pregnancy (aOR: 0.57; 95% CI: 0.54–0.60), and multiparous women with singleton cephalic term pregnancy without scar (aOR: 0.41; 95% CI: 0.30–0.55).Conclusion The rate of cesarean delivery in our Chinese population has declined significantly in the past few years.
