摘要
目的:分析双绒毛膜双羊膜囊(dichorionic diamniotic,DCDA)双胎出生体重不均衡的危险因素。方法:回顾性分析2014年1月1日至2017年12月31日我国11家医院分娩的1757例DCDA病例。以双胎新生儿出生体重差≥20%为出生体重不均衡诊断标准,据此将1757例分为出生体重均衡组(1520例)和出生体重不均衡组(237例)。分析孕妇的一般情况及出生体重不均衡的危险因素。采用Mann-Whitney U检验、χ^2检验或Fisher精确概率法,以及logistic回归分析进行统计分析。结果:出生体重不均衡组与出生体重均衡组相比,妊娠期高血压疾病[24.5%(58/237)与12.8%(194/1520)]、胎儿结构异常[4.2%(10/237)与1.0%(15/1520)]、胎儿窘迫[6.3%(15/237)与1.4%(21/1520)]、脐带异常[3.8%(9/237)与1.2%(18/1520)]、脐带附着异常[3.8%(9/237)与1.4%(21/1520)]等发生率较高(χ^2值分别为22.882、15.160、22.602、7.607及34.904,P值均<0.05),但胎膜早破的发生率较低[11.0%(26/237)与16.5%(250/1520),χ^2=4.645,P=0.034]。将单因素分析中差异有统计学意义的变量纳入多因素logistic回归分析发现,DCDA双胎出生体重不均衡的危险因素是妊娠期高血压疾病(OR=2.258,95%CI:1.620~3.148,P<0.001)、胎儿结构异常(OR=4.268,95%CI:1.892~9.631,P<0.001)、脐带异常(OR=2.889,95%CI:1.245~6.705,P=0.014)、脐带附着异常(OR=2.318,95%CI:1.012~5.311,P=0.047)。结论:DCDA双胎发生出生体重不均衡与妊娠期高血压疾病、胎儿结构异常、脐带异常、脐带附着异常等危险因素有关。
Objective To investigate the risk factors of birth weight discordance in dichorionic diamniotic(DCDA)twins.Methods This study retrospectively analyzed 1757 cases of DCDA twin pregnancies from 11 Chinese hospitals from January 1,2014,to December 31,2017.Birth weight discordance was defined as≥20%difference between the twins.All cases were divided into two groups:the concordant group(n=1520)and discordant group(n=237).General information was compared and the high-risk factors of birth weight discordance were analyzed.Mann-Whitney U test,Chi-square test or Fisher's exact test,and logistic regression analysis were used as statistical methods.Results Compared with the concordant group,the discordant group showed a higher incidence of hypertensive disorders of pregnancy[24.5%(58/237)vs 12.8%(194/1520),χ^2=22.882,P<0.05],fetal structural malformations[4.2%(10/237)vs 1.0%(15/1520),χ^2=15.160,P<0.05],fetal distress[6.3%(15/237)vs 1.4%(21/1520),χ^2=22.602,P<0.05],umbilical cord abnormalities[3.8%(9/237)vs 1.2%(18/1520),χ^2=7.607,P<0.05]and abnormal placental cord insertion[3.8%(9/237)vs 1.4%(21/1520),χ^2=34.904,P<0.05],but lower incidence of premature rupture of membranes[11.0%(26/237)vs 16.5%(250/1520),χ^2=4.645,P=0.034].Logistic regression analysis showed that the independent risk factors of birth weight discordance in DCDA twins were hypertensive disorders of pregnancy(OR=2.258,95%CI:1.620-3.184,P<0.001),fetal structural malformations(OR=4.268,95%CI:1.892-9.631,P<0.001),umbilical cord abnormalities(OR=2.889,95%CI:1.245-6.705,P=0.014)and abnormal placental cord insertion(OR=2.318,95%CI:1.012-5.311,P=0.047).Conclusions Hypertensive disorders of pregnancy,fetal structural malformations,umbilical cord abnormalities and abnormal placental cord insertion may be the risk factors of birth weight discordance in DCDA twins.
