Numerous studies show a growing trend in cesarean section rates throughout the world, including Iran. However, existing evidence in our country is scant and previous reports are restricted to short time periods. The aim of the current study is to measure the trend in cesarean sections (CS) rates over the past 30 years in a referral hospital in Tehran.
We routinely collected data on the demographic characteristics of all women who gave birth in the hospital during the study period. The mode of delivery and the personnel in charge of delivery has likewise been recorded for each birth during the study period. The data were extracted from medical records and entered into a structured checklist.
The rate of CS out of all deliveries increased from 14.3% in 1979 to 22.7% in 1989, 52.5% in 1999, and 85.3% in 2009 (P < 0.001). The most common reason for CS was a repeated section. The percentage of vaginal deliveries performed by midwives has not changed significantly and the number of both midwives and obstetricians per 1000 births has increased, from 2.8 to 15.4 midwives per 1000 births and from 5.5 to 23.0 obstetricians per 1000 births.
Immediate strategies should be adopted to prevent the rising trend and increasing number of unnecessary CS in Iran.
许多研究表明，包括伊朗在内的全球剖宫产率呈上升趋势。然而，我国现有的证据很少，以前的报告仅限于短时间内。本研究的目的是衡量过去 30 年在德黑兰一家转诊医院的剖宫产率趋势。
我们常规收集了研究期间医院所有分娩妇女的人口统计学特征数据。同样，还记录了研究期间每次分娩的分娩方式和负责分娩的人员。数据从病历中提取并输入到结构化检查表中。
剖宫产率从 1979 年的 14.3%上升到 1989 年的 22.7%、1999 年的 52.5%和 2009 年的 85.3%（P<0.001）。剖宫产最常见的原因是重复剖宫产。助产士实施的阴道分娩比例没有明显变化，每千名分娩的助产士和产科医生数量有所增加，从每千名分娩的 2.8 名增加到 15.4 名，从每千名分娩的 5.5 名增加到 23.0 名。
应立即采取策略，防止伊朗剖宫产率上升和不必要剖宫产数量增加的趋势。
