异位妊娠相关因素的logistic回归分析

Logistic Regression Analysis of Factors Related to Ectopic Pregnancy

目的探讨引起异位妊娠的相关因素。方法异位妊娠孕妇210例作为观察组,按照1∶2随机选择同期正常妊娠者420例作为对照组,对可能影响异位妊娠的因素资料进行单因素分析与logistic回归分析。结果单因素分析共筛选出9个因素与异位妊娠有关;以异位妊娠为应变量,其他统计量作为自变量赋值后进行logistic非条件多因素分析,结果筛选出5个主要的危险因素为妇科炎症、孕产史、宫内节育器、腹部手术史、应用紧急避孕药物。结论异位妊娠与多种因素有关,对异位妊娠的高危人群加强监测,并进行指导:采取安全有效避孕措施;治疗妇科炎症;提高人工流产手术操作技术和其他宫腔操作技术;掌握IUD置放的适应证。

Objective To explore the risk factors in the occurrence of ectopic pregnancy.Methods Pregnant women,210 cases of ectopic pregnancy as the observation group;the same period in accordance with 1 ∶2 normal pregnancies were randomly selected as the control group,on the factors that may affect the ectopic pregnancy data of single-factor analysis and logistic regression analysis.Results Single-factor analysis results showed that 9 factors and ectopic pregnancy-related with ectopic pregnancy as the dependent variable,other statistics assignment as independent variables after the non-conditional multi-factor Logistic regression analysis,the results of selected five major risk factors：gynecological inflammation,pregnancy history,intrauterine devices,history of abdominal surgery,the application of emergency contraceptives.Conclusion Ectopic pregnancy with a variety of factors,high risk of ectopic pregnancy to strengthen the monitoring and guidance to do：take safe and effective contraceptive measures,treatment,gynecological inflammation,increased abortion and intrauterine operation techniques,and other operating techniques;master IUD placement indication.
