Abstract: Objective：To investigate the positive detection rate of U. urealyticum in female migrants of child-bearing age from Ningxia Hui Autonomous Region. Methods：The subjects were selected through a multi-stage cluster sampling. A total of female migrants were investigated using a structured questionnaire, and tested their samples of cervical ecretion. Results：There were 286 positive testing results in 762 female migrants, with the positive rate 37.53%. The differences in positive rats were significant in those women of different age, education, contraception, cleanliness of vaginal secretion and infection of pathogens (all P＜0.05). The stepwise logistic regression analysis showed that the positive rate in women using condom was significantly lower than that in women not using condom (OR=0.552, 95%CI: 0.380-0.802), and that the positive rate in women using IUD was higher (OR=1.311, 95%CI: 0.894-1.922). The positive rate in those women who had 3 or more times of pregnancy was higher than that in women without pregnancy (OR=1.812, 95%CI: 1.100-2.985). Conclusions：There was high detection rate of U. urealyticum in female migrants of child-bearing age. In order to improve their reproductive health, it is necessary to enhance the education of reproductive health, to advocate the use of condom, and to promote the general gynecological survey in those women with 3 or more times of pregnancy.
