Predictors of cesarean delivery in pregnant women with gestational diabetes mellitus
Abstract Purpose The aim of this study was to evaluate which risk factors may lead patients with gestational diabetes mellitus to cesarean delivery. Methods This was a retrospective, descriptive study. The subjects of the study were pregnant women with gestational diabetes mellitus attending a public maternity hospital in the south of Brazil. The primary outcomes assessed were based on maternal and fetal characteristics. The data were correlated using an odds ratio (OR) with a 95% confidence interval (95%CI), calculated using multinomial logistic regression. Results A total of 392 patients with gestational diabetes mellitus were analyzed, and 57.4% of them had cesarean deliveries. Among the maternal characteristics, the mean age of the patients and the pregestational body mass index were greater when a cesarean delivery was performed (p = 0.029 and p < 0.01 respectively). Gestational age at birth, newborn weight, weight class according to gestational age, and Apgar score were not significant. The analysis of the OR showed that the chance of cesarean delivery was 2.25 times (95%CI = 1.49-2.39) greater if the pregnant woman was obese, 4.6 times (95%CI = 3.017-7.150) greater if she was a primigravida, and 5.2 times (95% CI = 2.702-10.003) greater if she had a previous cesarean delivery. The other parameters analyzed showed no differences. Conclusion The factors that led to an increase in the occurrence of cesarean deliveries included history of a prior cesarean section, first pregnancy, and obesity.
