Abstract To analyze the risk factors of early pregnancy loss of pregnant women. Methods: The clinical data of 680 pregnant women from March to February 2018 were collected, which included 80 women with early pregnancy loss in 13 gestational weeks in study group and 600 normal pregnant women in control group. The incidence of early pregnancy loss was compared among pregnant women with different characteristics, and the risk factors of pregnancy loss were analyzed. Results: Among 680 pregnant women, the incidence of early pregnancy loss was 11.8%. The rates of previous abortion history, congenital uterine malformation, acquired coagulopathy, early viral infection, polycystic ovary syndrome of women with early pregnancy loss were significant higher than those of normal pregnant women (P<0.05). There was no significant different in the incidence of pregnancy loss among women with different age (P>0.05). When the pregnancy loss was used as the dependent variable, and previous abortion history, congenital uterine malformation, acquired coagulopathy, early viral infection, polycystic ovary syndrome from the single factor analysis results were as the independent variable, the multivariate logistic regression analysis showed that congenital uterine malformation and acquired coagulopathy were risk factors for pregnancy loss (OR=4.987, 4.683). Conclusion: There is a certain incidence of early pregnancy loss of pregnant women with different age. The congenital abnormalities of the uterine cavity and history of acquired diseases maybe influent the early pregnancy loss.
