Placenta previa increases the risks of obstetrical complications. Many studies have reported a link between various ABO blood types and pregnancy complications. This study is aimed at describing and comparing the characteristics and outcomes of women with placenta previa by ABO blood type.
Data for this study was obtained from a retrospective cohort study between January 1, 2014, and June 30, 2019, of all clinically confirmed placenta previa in a university-based tertiary medical center. Both types of A, B, O, AB, and combining O and non-O blood types were compared to the characteristics and outcomes.
1678 participants with placenta previa were included in this study. The highest participants were blood type O with 666 (39.7%), followed by type A with 508 (30.3%) and type B with 395 (23.5%), and the lowest participants were AB with 109 (6.5%). Blood type AB had a higher incidence of antepartum hemorrhage ( = 0.017), predelivery anemia ( = 0.036), and preterm birth ( = 0.015) in placenta previa women. Meanwhile, the incidence of rhesus D positive (97.9% vs. 95.8%, = 0.012) and twins (5.0% vs. 2.7%, = 0.011) was higher in the non-O group, and the incidence of neonatal asphyxia (5.9% vs. 9.2%, = 0.016) was lower in the non-O group.
Type AB blood may be a potential risk factor for women with placenta previa. This finding may help provide any obstetrician to predict the risk of complication for placenta previa women by the ABO blood types.
前置胎盘增加了产科并发症的风险。许多研究已经报道了各种 ABO 血型与妊娠并发症之间的联系。本研究旨在描述和比较 ABO 血型与前置胎盘妇女的特征和结局。
本研究的数据来自于 2014 年 1 月 1 日至 2019 年 6 月 30 日期间，在一所大学附属三级医疗中心进行的一项回顾性队列研究，所有临床确诊的前置胎盘患者均纳入研究。比较了两种 A、B、O、AB 型血和 O 型和非 O 型血组合的特征和结局。
本研究共纳入 1678 例前置胎盘患者。参与者中 ABO 血型 O 型最多，有 666 例（39.7%），其次是 A 型 508 例（30.3%）和 B 型 395 例（23.5%），AB 型最少，有 109 例（6.5%）。AB 型血前置胎盘妇女产前出血（ = 0.017）、产前贫血（ = 0.036）和早产（ = 0.015）发生率较高。同时，非 O 型组 RhD 阳性（97.9% vs. 95.8%， = 0.012）和双胞胎（5.0% vs. 2.7%， = 0.011）的发生率较高，非 O 型组新生儿窒息（5.9% vs. 9.2%， = 0.016）的发生率较低。
AB 型血可能是前置胎盘妇女的一个潜在危险因素。这一发现可能有助于为产科医生提供通过 ABO 血型预测前置胎盘妇女并发症风险的依据。
