Background: China has witnessed a rapid increase of caesarean section (CS) rates in recent years. Several non-clinical factors have been cited as contributing to this trend including maternal request and perceived convenience. We aimed to assess preferences for mode of delivery and factors for preferences for CS in China to inform the development of future interventions to mitigate unnecessary CSs.

Methods and Findings: We conducted a mixed-methods systematic review and included longitudinal, cross-sectional studies and qualitative studies in mainland China, Hong Kong and Taiwan that investigated preferences for mode of delivery among women and family members and health professionals, and the reasons underlying such preferences. We searched MEDLINE/PUBMED, EMBASE, CINAHL, Popline, PsycINFO, Global Health Library and one Chinese database (CNKI) using a combination of the following key terms “caesarean section”, “preference”, “choice”, “knowledge”, “attitude”, “culture”, “non-clinical factors”, “health professionals-patient relations” between 1990 and 2018 without language restriction. Meta-analysis of quantitative studies and meta-synthesis of qualitative studies were applied.

We included 66 studies in this analysis: 47 quantitative and 19 qualitative. For the index pregnancy, the pooled proportions of preference for CS reported by women in longitudinal studies were 14% in early or middle pregnancy (95%CI 12-17%) and 21% in late pregnancy (95%CI 15-26%). In cross-sectional studies, the proportions were 17% in early or middle pregnancy (95%CI 14-20%), 22% in late pregnancy (95%CI 18-25%) and 30% at postpartum (95%CI 19-40%). Women’s preferences for CS were found to rise as pregnancy progressed (a mean difference to test preference change across longitudinal studies; mean difference 7%, 95%CI 1%-13%). One longitudinal study reported that the preference for CS among women’s partners increased from 8% in late pregnancy to 17% in the immediate postpartum. In addition, 18 quantitative studies revealed some pregnant women did not have straightforward preference for a mode of delivery, even in late pregnancy ranging from 4% to 34%. The qualitative meta-synthesis found that women’s perceptions of CS as preferable were based on prioritizing the baby’s and woman’s health and appeared to intensify through interactions with the system. Women valued the convenience of bypassing labour because of fear of pain, antagonistic relations with providers, and beliefs of deteriorating quality of care during labour and vaginal birth fostering the feeling that CS is the safest option. Health professionals’ preference for CS was influenced by financial drivers and malpractice fears. This review has some limitations, including high heterogeneity (despite sub-group and sensitivity analysis) in the quantitative analysis, and the potential for over-reporting of women’s preferences for CS in the qualitative synthesis (due to some included studies only including women who requested CS).

Conclusion: Despite a minority of women expressing a preference for CS, individual, health system and socio-cultural factors converge contributing to high CS rate in mainland China, Hong Kong and Taiwan. In order to reduce the use of unnecessary CS, interventions need to address all these non-clinical factors and concerns.
