Background: The cesarean section rate (CSR) has been a main concern worldwide. The present study aimed to investigate the CSR in Beijing, China, and to analyze the related factors of CS delivery.
Methods: An observational study was conducted in 15 medical centers in Beijing using a systemic cluster sampling method. In total, 15,194 pregnancies were enrolled in the study between June 20, 2013 and November 30, 2013. Independent t-tests and Pearson's Chi-square test were used to examine differences between two groups, and related factors of the CSR were examined by multivariable logistic regression.
Results: The CSR was 41.9% (4471/10,671) in singleton primiparae. Women who were more than 35 years old had a 7.4-fold increased risk of CS delivery compared with women <25 years old (odd ratio [OR] = 7.388, 95% confidence interval [CI] = 5.561–9.816, P < 0.001). Prepregnancy obese women had a 2-fold increased risk of CS delivery compared with prepregnancy normal weight women (OR = 2.058, 95% CI = 1.640–2.584, P < 0.001). The excessive weight gain group had a 1.4-fold increased risk of CS delivery compared with the adequate weight gain group (OR = 1.422, 95% CI = 1.289–1.568, P < 0.001). Gestational diabetes mellitus (GDM) women and DM women had an increased risk of CS delivery (1.2- and 1.7-fold, respectively) compared with normal blood glucose women. Women who were born in rural areas had a lower risk of CS delivery than did those who were born in urban areas (OR = 0.696, 95% CI = 0.625–0.775, P < 0.001). The risk of CS delivery gradually increased with a decreasing education level. Neonates weighing 3000–3499 g had the lowest CSR (36.2%). Neonates weighing <2500 g had a 2-fold increased risk of CS delivery compared with neonates weighing 3000–3499 g (OR = 2.020, 95% CI = 1.537–2.656, P < 0.001). Neonates weighing ≥4500 g had an 8.3-fold increased risk of CS delivery compared with neonates weighing 3000–3499 g (OR = 8.313, 95% CI = 4.436–15.579, P < 0.001).
Conclusions: Maternal age, prepregnancy body mass index, gestational weight gain, blood glucose levels, residence, education level, and singleton fetal birth weight are all factors that might significantly affect the CSR.
