摘要:

目的 旨在通过meta分析总结双胎妊娠早产的危险因素。方法 使用计算机检索中国知网(CNKI)、万方(WanFang)、维普(VIP)、中国生物医学文献数据库(CBM)、PubMed、Embase、Cochrane Library、Wed of Science数据库,收集公开发表的双胎妊娠早产危险因素的文献,检索时间限定为建库至2025年8月,由2名研究人员独立提取信息与质量评价,使用RevMan 5.4与Stata 17.0软件进行meta分析。结果 共纳入10篇文献,总计样本量4 993例。Meta分析结果显示,单绒毛膜性(OR=2.34,95%CI:1.58~3.48)、妊娠期高血压(OR=3.10,95%CI:2.48~3.87)、胎膜早破(OR=3.68,95%CI:1.06~12.81)、瘢痕子宫(OR=1.96,95%CI:1.51~2.53)、绒毛膜羊膜炎(OR=2.72,95%CI:1.50~4.93)、羊水异常(OR=3.29,95%CI:2.11~5.13)、脐带异常(OR=3.21,95%CI:1.43~7.23)、阴道炎(OR=3.40,95%CI:1.74~6.66)为双胎妊娠早产的危险因素; BMI为双胎妊娠早产的保护性因素(OR=0.88,95%CI:0.81~0.95)。结论 单绒毛膜性、妊娠期高血压、胎膜早破、瘢痕子宫、绒毛膜羊膜炎、羊水异常、脐带异常、阴道炎等是双胎早产危险因素,建议临床人员积极筛查双胎妊娠中的早产高危人群,并及时采取干预措施,以预防妊娠早产发生。

Abstract:

Objective This meta-analysis aimed to systematically summarize the risk factors associated with preterm birth in twin pregnancies. Methods We comprehensively searched the following electronic databases from inception to August 2025: China National Knowledge Infrastructure (CNKI), WanFang Database, VIP Database, China Biology Medicine disc (CBM), PubMed, Embase, Cochrane Library, and Web of Science. Literature published on the risk factors for preterm birth in twin pregnancies was included. Two researchers independently performed data extraction and quality assessment. Meta-analysis was conducted using RevMan 5.4 and Stata 17.0 software. Results A total of 10 studies involving 4, 993 participants were included. The meta-analysis identified the following significant risk factors for preterm birth in twin pregnancies: monochorionicity (OR=2.34, 95%CI: 1.58-3.48), gestational hypertension (OR=3.10, 95%CI: 2.48-3.87), premature rupture of membranes (OR=3.68, 95%CI: 1.06-12.81), uterine scar (OR=1.96, 95%CI: 1.51-2.53), chorioamnionitis (OR=2.72, 95%CI: 1.50-4.93), abnormal amniotic fluid (OR=3.29, 95%CI: 2.11-5.13), umbilical cord abnormalities (OR=3.21, 95%CI: 1.43-7.23), and vaginitis (OR=3.40, 95%CI: 1.74-6.66). Body mass index (BMI) was found to be a protective factor (OR=0.88, 95%CI: 0.81-0.95). Conclusion Monochorionicity, gestational hypertension, premature rupture of membranes, uterine scar, chorioamnionitis, abnormal amniotic fluid, umbilical cord abnormalities, and vaginitis are identified as risk factors for preterm birth in twin pregnancies. It is recommended that clinicians actively screen for these high-risk factors in twin pregnancies and implement timely interventions to prevent preterm birth.
