月经及生殖状况与盆腔子宫内膜异位症关系的探讨

目的：探讨盆腔子宫内膜异位症（简称内异症）与月经及生殖状况的关系。方法：采用成组病例对照方法调查91例病例组及67例对照组病人的月经及生殖情况。结果：单因素分析结果显示，原发性痛经及继发性痛经均内异症发病的危险因素，t初孕年龄及t初产年龄≤24岁、N孕次≥2次及使用避孕器避孕这4个因素为可能的保护因素。非条件logistic多元回归分析显示，原发性痛经、继发性痛经为子宫内膜异位症的危险因素，t初孕年龄≤24岁与使用避孕器避孕有正交互作用，并对发病有保护作用。而单因素分析中，t初孕年龄≤24岁等4个可能的保护因素却未能显示与发病有联系。结论：原发性痛经是盆腔子宫内膜异位症可能的危险因素，积极有效地防治原发性痛经有助于预防内异症的发生。

Relationship Between Endometriosis and Menstruation as well as Gestational Status

To explore the relationship between endometriosis with menstruation as well as gestational status. [Methods] Case- group comparative trial was applied to investigate the menstruation as well as gestational status in 91 cases of endometriosis and 67 cases of non - endometriosis in the same period. [ Results ] Single - factor analysis showed that primary dysmenorrhea and secondary dysmenorrhea were the risk factors of endometriosis. Age of primigravida and primiparity at 24 or less, times of pregnancy over 2 and the application of contraceptive device were the possibly protective factors. Unconditional logistic multivariate regression analysis showed that primary dysmenorrhea and secondary dysmenorrhea were the risk factors of endometriosis, and there was a positive interaction between the age of primigravida and the application of contraceptive device. [Conclusion] Primary dysmenorrhea was the risk factor of endometriosis.
