异位妊娠危险因素Logistic回归分析

目的 研究异位妊娠发生的危险因素，为提高其防治水平提供科学有力证据。方法 采用Logisitic回归分析法，选取2011年3月-2013年10月在该院妇产科住院治疗140例异位妊娠患者作为研究对象，进行异位妊娠相关因素的多元回归分析。结果 流产史、异位妊娠史、盆腔感染史和宫内节育器是异位妊娠发生的显著危险因素,其优势比（odds ratio，OR）及95.0%可信区间（confidence interval,CI）分别为OR=3.79,95.0% CI：2.23～6.42、OR=6.98,95.0% CI：2.64～15.53、OR=4.21,95.0%CI：2.43～7.15和OR=2.19,95.0%CI：1.21～3.98。结论 加强生殖健康教育、减少非意愿妊娠和预防盆腔感染，可降低异位妊娠的风险。

Logistic Regression Analysis of the Risk Factors of Ectopic Pregnancy

Objective To study the risk factors related to ectopic pregnancy in order to provide a scientific evidence for improving the level of prevention and treatment. Methods 140 cases of patients with ectopic pregnancy hospitalized in the Department of Obstetrics and Gynecology of our hospital from March, 2011 to October, 2013 were selected as the subjects. And logistic regression analysis method was used to analyze the factors related to ectopic pregnancy. Results The main risk factors related to ectopic pregnancy were history of abortion with the odds ratio （OR） =3.79, 95% confidence interval （CI）：2.23-6.42; and history of ectopic pregnancy with OR=6.98; 95% CI： 2.64-15.53; history of pelvic infection with OR=4.21, 95% CI：2.43-7.15;the intrauterine device with OR=2.19, 95%CI：1.21-3.98. Conclusion Strengthening the reproductive health education, reducing the unwanted pregnancy and preventing pelvic infection, can reduce the risk of ectopic pregnancy.
