人工流产与生殖道感染相关性分析

Analysis on correlation between induced abortion and reproductive tract infection

目的探讨人工流产次数与生殖道感染（RTI）的相关性。方法选择山东省农村已婚育龄妇女4429例，应用二值多元Logistic回归模型分析人工流产与生殖道感染的相关关系。结果有无人工流产史的育龄妇女人群的生殖道感染率差异有统计学意义（χ^2=7．076。P=0．008），人工流产史与生殖道感染有关联，OR为1．231,95％CI=1．0561．434。随着人工流产次数的增加，生殖道感染的危险性也升高，特别是人工流产次数在3次以上时，危险性增加更明显。结论人工流产是农村妇女生殖道感染的危险因素，人工流产次数增加，生殖道感染的危险性升高。

Objective To explore the correlation between induced abortion and reproductive tract infection. Methods A case-control study of 2507 RTIs women and 1443 health women and the binary logistic regression analysis were used to study the correlation between induced abortion and reproductive tract infection in rural area. Results There was a significant difference in rate of RTIs between case and control groups. The logistic regression model analysis showed that RTIs was related to the experience of induced abortion （ OR = 1. 231,95 % CI ： 1. 056 - 1. 434）, the women experienced more times of induced abortion had higher risk of RTIs, especially experienced more than three times. Conclusion The experience of induced abortion was risk factor of RTIs, and the more times of induced abortion, the more risk.
