- Abstract: OBJECTIVE: To study a potential relationship between preterm labor and lymphocyte to monocyte ratio(LMR).METHODS: This retrospective cohort study was conducted in Second Affiliated Hospital of Chongqing Medical University from August 2016 to November 2017. Totally 100 pregnant women who delivered between 28 th to 37 th gestational week were included as the study group,and 116 pregnant women who delivered after 37 th gestational week were as the control group. The data of routine blood test from 11 th to 13 th gestational week and 28 th to 30 th gestational week were observed and compared.RESULTS: The LMR value of preterm women was significantly higher than that of those who delivered at term(early pregnancy 4.90±1.40 vs. 4.31±1.30,P<0.01;middle and advanced stage of pregnancy 3.54±0.93 vs. 2.95±0.64,P<0.01). A negative correlation was observed between the level of LMR and the gestational weeks of termination of pregnancy(r=-0.350,P<0.01).CONCLUSION: The value of LMR in pregnancy is associated with the occurrence of preterm labor. Therefore,it is necessary to make further study.
