A thirty-year analysis of cesarean section rate in gestational diabetes and normal pregnant population in Tehran, Iran: a concerning trend

Abstract

Background: The aims of this study were to analyze the trend of cesarean section (CS), determining possible risk factors and also comparing the rate of CS in mothers with gestational diabetes (GDM) and normal pregnant population. Materials and methods: A hospital-based midwives data collection including 37,997 pregnancies in Tehran was used for this study. The study population included all women giving birth between 1 January 1980 and 31 December 2009. Results: The global rate for CS was 37.8 and 85.9% in normal pregnant population and GDM subjects, respectively. An increase in the rate of CS was observed in normal population from 16.97% during 1980–1989 to 71.08% during 2000–2009. There was a similar upward trend for GDM subjects from 79.17 to 93.55%. The most frequent indications for CS in GDM subjects were unsuccessful induction (31%) and repeat CS (22.76%). Conclusion: The rate of CS is surprisingly very high in normal pregnant population as well as subjects with GDM. This should be an alarming issue for healthcare policy-makers and a trigger for monitoring situation in the country.
