Abstract: Objective This study aim to explore the correlation between adverse pregnancy outcome and TORCH infection.Methods 1 892 pregnant women were enrolled in our hospital from October 2013 to October 2015,and the clinical data of all pregnant women were retrospectively analyzed. All pregnant women were divided into normal pregnancy group according to pregnancy outcome group 1 788 cases,104 cases of adverse pregnancy group. TORCH infection in pregnant women from two group were detected and compared. Results TORCH-IgM was positive in all the pregnant women,accounting for 1.85% （35/1 892）. The positive rate of TORCH-IgM in the adverse pregnant group was higher than that in the normal pregnancy group （P<0.05）.The positive rate of TORCH-IgG in all pregnant women was 1.16% （22/1 892）,but the difference was statistically significant （P<0.05）.In all pregnant women,293 cases were diagnosed with umbilical cord blood,9 cases of TORCH-IgM positive,accounting for 3.07% （9/293）; and adverse pregnancy group TORCH-IgM positive rate was higher than the normal pregnancy group,the difference was statistically significant （P<0.05）.The positive rate of TORCH-IgG was 1.71% （5/293）,while the positive rate of TORCH-IgG in the adverse pregnant group was higher than that in the normal pregnancy group （P<0.05）,and the difference was statistically significant （P<0.05）. Conclusion There is a significant correlation between the adverse outcome of pregnant women and TORCH infection,and the possibility of TORCH infection in both pregnant women and newborns. TORCH should be used as routine prenatal examination,early diagnosis,early treatment and improvement of pregnancy ending.
