Variation trend and influential factors for cesarean section rate in a general hospital in Changsha from 2008 to 2017

Objective: To know about the cesarean section rate and the changes of the indications for cesarean section in Changsha from 2008 to 2017, and to provide scientific basis for decreasing the cesarean section rate. Methods: We collected the clinical data of deliveries in a general hospital in Changsha from January 2008 to December 2017, and analyzed the cesarean section rate, the changes of the indications for cesarean section and the influential factors. Results: The cesarean section rate in this hospital was 50.0% from 2008 to 2017, and the cesarean section due to social factors showed a decreasing trend year by year. Multiple-factor analysis of the cesarean section shows that advanced age, multi-parous pregnancy, gravida (≥4 times), abnormal fetal position and heavy fetus weight were dangerous factors, and the multipara was a protective factor. Conclusion: The cesarean section rate in a general hospital in Changsha is at a high level, and there are many factors affecting cesarean section. It is necessary to optimize the strategies and measures to reduce the cesarean section rate, and to control the cesarean section rate in a reasonable range.
