Women's cesarean section preferences and influencing factors in relation to China's two-child policy: a cross-sectional study.

Objective: This study explored women's preference for cesarean section (CS) and the preference for cesarean sections' influencing factors, particularly nonmedical factors.

Methods: A cross-sectional study was conducted in four tertiary hospitals in Hohhot. We recruited 1,169 pregnant women at ≥ 28 gestational weeks and classified subjects into three groups by delivery mode preference: vaginal birth (VB), CS, and "no clear preference". We identified the influencing factors of women's choices by multinomial logistic regression. The adjusted relative-risk ratios (aRRRs) for the factors affecting the preference for CS and "no clear preference" categories and their 95% CIs were computed, using the preference for VB as the reference group.

Results: VB was preferred by 80.3% of the subjects, 8.8% preferred CS, and 10.9% had not decided yet. In the multinomial logistic regression, pregnant women intending to have more than one child were less likely to prefer CS (aRRR: 0.37; 95% CI: 0.22-0.61); choosing a lucky day for baby birth was the strongest factor for CS preference (aRRR: 12.36; 95% CI: 6.62-23.08), and other factors for CS preference were being aged 40 years and above (aRRR: 4.21; 95% CI: 1.43-12.40), being ethnic minority (aRRR: 2.00; 95% CI: 1.17, 3.41), feeling difficulty in getting pregnant (aRRR: 2.23; 95% CI: 1.20, 4.13), and having husband's preference for CS (aRRR: 7.62; 95% CI: 4.00-14.54). The top reasons for preferring CS were the belief that CS was safer (51.5%), associated with less pain (40.8%), and better for baby's and woman's health (24.3% and 22.3%, respectively).

Conclusion: Less than one-tenth of the study subjects preferred CS. The cultural beliefs had the strongest influence on the decision of delivery mode. Those intending to have two or more children following the two-child policy were less likely to choose CS.
