The cesarean section rate in Vietnam has been increasing especially in urban area. However, limited evidence identified regarding socio-demographic factors of the cesarean section birth. The objective of this study was to determine the current cesarean birth rate and the associated socio-demographic factors among mothers in Nha Trang city, south-central Vietnam.
A community-based cross-sectional study was conducted between October and November in 2016 as part of a carriage survey conducted in 27 communes of Nha Trang city. From each commune, 120 mothers and their children less than 2 years old were randomly selected. Mothers were asked to answer standardized questions regarding socio-demographic information and mode of birth. Multivariate logistic regression was adopted to examine associations between socio-demographic variables and mode of birth.
Of 3148 participants, the number of cesarean births was 1396 (44.3 %). Older maternal age (≥ 30 years old), having another child going to school or kindergarten, monthly income more than 644 USD, gestational weeks at birth over 42 weeks, and low (< 2500 g) or high (≥ 3500 g) birth weight were associated with higher likelihood of cesarean births.
The CS rate obtained in this study was more than twice of what is recommended by the World Health Organization, which is consistent with the previous nation-wide study in Viet Nam. Further monitoring is suggested to examine the non-medical reason for the increased CS rate.
越南的剖宫产率一直在上升，尤其是在城市地区。然而，关于剖宫产分娩的社会人口学因素的证据有限。本研究的目的是确定越南中南部芽庄市母亲的当前剖宫产率及相关社会人口学因素。
2016年10月至11月进行了一项基于社区的横断面研究，作为在芽庄市27个公社进行的一项母婴调查的一部分。从每个公社中随机选择120名母亲及其2岁以下的孩子。母亲们被要求回答关于社会人口学信息和分娩方式的标准化问题。采用多因素逻辑回归分析来检验社会人口学变量与分娩方式之间的关联。
在3148名参与者中，剖宫产分娩的人数为1396人（44.3%）。母亲年龄较大（≥30岁）、有另一个孩子上学或上幼儿园、月收入超过644美元、出生孕周超过42周以及低出生体重（<2500克）或高出生体重（≥3500克）与剖宫产分娩的可能性较高相关。
本研究中获得的剖宫产率是世界卫生组织建议率的两倍多，这与越南之前的全国性研究一致。建议进一步监测以检查剖宫产率上升的非医学原因。
