目的探讨盆腔子宫内膜异位症(EM)发病的相关因素。方法对唐山市两家医院76例EM患者(病例组)及对照组非盆腔EM的其他患者84例进行问卷调查,采用x~2检验,t检验,多因素非条件Lo- gistic回归模型进行分析。结果单因素分析发现:脑力劳动、存在变态反应、月经周期缩短(≤27 d)、有原发性和继发性痛经、人工流产次数增多(≥2次)使EM的危险性增加。多因素非条件Logistic回归分析发现:脑力劳动(OR=3.26)、原发性痛经和继发性痛经(DR=6.23,5.91)、人工流产次数的增加(≥2,OR=2.39)为EM的危险因素。结论盆腔EM的发病可能与脑力劳动、原发性和继发性痛经以及人工流产次数有关联。
Objective To investigate the related factors of pelvic endometriosis (EM). Methods Totally 76 cases of EM patients (case group) and 84 cases of non-pelvic EM in the two hospitals of Tangshan City were investigated by questionnaires, and analyzed by x ~ 2 test, t test and multivariate non-conditional Lo-gistic regression model . Results Univariate analysis showed that there was an allergic reaction and a shortened menstrual cycle (≤27 days) with primary and secondary dysmenorrhea. The increased number of induced abortion (≥2 times) increased the risk of EM. Multivariate non-conditional Logistic regression analysis showed that the increase of the number of induced abortion (≥2, OR = 2.39) in EM (OR = 3.26), primary dysmenorrhea and secondary dysmenorrhea (DR = 6.23,5.91) Risk factors. Conclusion The incidence of pelvic EM may be related to mental labor, primary and secondary dysmenorrhea and the number of induced abortion.
