AIM: To document the rise in prepartum and intrapartum caesarean section and the demographic and medical factors contributing to the rise. METHODS: Data from 52,423 deliveries between January 1997 to May 2005 were analysed for yearly change in caesarean section rates and multiple demographic and medical factors. RESULTS: The prepartum caesarean section rate increased by 1.6% per year and the intrapartum caesarean section rate by 0.8% per year. There was no increase in the overall prevalence of obesity, short stature, advanced maternal age, medical complications or previous caesarean section. There were significant increases in nulliparity, private care, induction of labour and the use of electronic monitoring, but these were insufficient to explain the magnitude of the rise. CONCLUSION: The increase in prepartum and intrapartum caesarean section displayed was not fully explained by medical and demographic changes in the population.
目的:记录产前及产时剖宫产率的上升情况以及导致该上升的人口统计学和医学因素。 方法:分析了1997年1月至2005年5月间52423例分娩的数据,以了解剖宫产率的年度变化以及多种人口统计学和医学因素。 结果:产前剖宫产率每年上升1.6%,产时剖宫产率每年上升0.8%。肥胖、身材矮小、高龄产妇、医学并发症或既往剖宫产的总体患病率均未增加。初产、私立医疗护理、引产及电子监护的使用显著增加,但这些不足以解释上升幅度。 结论:所显示的产前及产时剖宫产率的上升不能完全由人群中的医学和人口统计学变化来解释。
