Abstract

Background: Antepartum hemorrhage (APH) is associated with perinatal mortality and maternal morbidity. Previous studies have reported that obesity in pregnancy adversely influences both fetal and neonatal outcomes. This study aimed to investigate gestational overweight and the risk of APH in pregnant women with complete placenta previa (CPP).

Methods: This was a retrospective cohort study of pregnant women with CPP delivery at our hospital from 2013 to 2015. Outcomes were stratified according to APH and non-APH.

Results: Of 193 pregnancies with CPP, 40.4% (78) were diagnosed with APH. Maternal weight and BMI at delivery were significantly decreased in women with APH (61.15 ± 8.73 vs. 65.22 ± 7.80, 24.47 ± 3.12 vs. 26.21 ± 2.85; P = 0.001, P = 0.001; respectively), and the prevalence of overweight at delivery was higher in the non-APH group compared to those in the APH group (54.9% (62) vs. 39.7% (27); OR 2.18; 95%CI [1.16-4.11]). After adjusting for gestation week and other potential confounding factors, maternal weight and BMI were associated with the APH (OR 0.95, 95%CI [0.91-0.99]; 0.85, 95%CI [0.75-0.97], respectively).

Conclusion: Appropriate weight gain during pregnancy may decrease the risk of antepartum hemorrhage in pregnant women with complete placenta previa.

妊娠超重降低完全性前置胎盘孕妇产前出血的风险：一项回顾性研究。

背景：产前出血（APH）与围产期死亡率和孕产妇发病率相关。先前的研究报道，妊娠期肥胖对胎儿和新生儿的结局都有不利影响。本研究旨在探讨完全性前置胎盘（CPP）孕妇妊娠期超重与APH的风险。方法：对我院2013 ~ 2015年CPP分娩孕妇进行回顾性队列研究。结果根据APH和非APH进行分层。结果：193例CPP妊娠中，40.4%（78例）诊断为APH。APH患者分娩时体重和BMI显著降低(61.15±8.73 vs. 65.22±7.80,24.47±3.12 vs. 26.21±2.85；P = 0.001, P = 0.001；非APH组分娩时超重的患病率高于APH组(54.9%（62）对39.7% (27)；或2.18;95%置信区间[1.16 - -4.11])。在调整妊娠周和其他潜在的混杂因素后，母亲体重和BMI与APH相关(OR 0.95, 95%CI [0.91-0.99]；0.85, 95%CI[0.75-0.97])。结论：妊娠期适当增加体重可降低完全性前置胎盘孕妇产前出血的风险。
