The present study aimed to investigate the CSR in Beijing, China, and to analyze the related lactors of CS delivery. Methods: An observational study was conducted in 15 medical centers in Beijing using a systemic cluster sampling naethod. In total, 15, 194 pregnancies were enrolled in the study between ,lune 20, 2013 and November 30, 2013. Independent t-tests and Pearson's Chi-square test were nsed 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 [Cl] = 5.561-9.816, P 〈 0.001 ). Prepregnancy obese women had a 2-1bid 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, geslational weight gain, blood glncose levels, residence, education level, and singleton fetal birth weight arc all factors that might significantly affect the CSR. 展开更多
