目的探讨异位妊娠(EP)发生的相关因素。方法选择本院2009年6月至2012年6月收治的EP患者130例为观察组,按照1∶2比例匹配同期早期宫内妊娠的健康女性260例作为对照组。将患者的一般情况、相关病史、避孕措施、生殖健康知识等进行单因素和多因素Logistic回归分析。结果 (1)单因素分析显示:观察组在产次、流产史、盆腔感染、异位妊娠史、腹部手术、不孕史、宫内节育器、口服避孕药、多个性伴侣以及生殖健康知识缺乏方面的构成比高于对照组(P<0.05)。(2)多因素分析结果表明,流产史(OR=3.604)、盆腔感染史(OR=1.686)、腹部手术(OR=1.743)、宫内节育器(OR=1.919)是EP发病的主要危险因素。结论 EP的发生并非为单一危险因素所致,加强性健康教育、减少非意愿妊娠是预防和降低EP发生的有效途径。
Objective To investigate the related factors of ectopic pregnancy (EP). Methods 130 patients with EP in our hospital from June 2009 to June 2012 were selected as the observation group. According to the ratio of 1: 2, 260 healthy women matched with early intrauterine pregnancy in the same period as the control group. The general situation of patients, related medical history, contraception, reproductive health knowledge, single factor and multivariate logistic regression analysis. Results (1) Univariate analysis showed that there was no significant difference in the incidence of abortion, abortion history, pelvic infection, history of ectopic pregnancy, abdominal surgery, history of infertility, intrauterine device, oral contraceptives, multiple sexual partners and lack of reproductive health knowledge The aspect ratio is higher than the control group (P <0.05). (2) Multivariate analysis showed that the main risk factors of EP were miscarriage history (OR = 3.604), history of pelvic infection (OR = 1.686), abdominal operation (OR = 1.743) and IUD . Conclusion The occurrence of EP is not caused by a single risk factor. To improve sexual health education and reduce unwanted pregnancies are effective ways to prevent and reduce the occurrence of EP.
