A Retrospective Study On The Relationship Between LMR And Preterm Delivery

Objective: This study was to probe a potential relationship between preterm labor and lymphocyte to monocyte ratio(LMR).Methods: This retrospective cohort study was conducted in the Second Affiliated Hospital of Chongqing Medical University.100 pregnant women who delivered between 28 th to 37 th gestational week were included as the study group,and 928 pregnant women who delivered after 37 th gestational week as the control group.The data of routine blood test at the first time of antenatal care from 28 th to 30 th gestational week were observed and compared to find whether LMR is associated with preterm labor.Results: The LMR value of preterm women was significantly higher than that of ones who delivered at term(P< 0.001).A negative correlation was observed between the level of LMR and the gestational weeks of termination of pregnancy(r =-0.350,P<0.001).Conclusions: The value of LMR in pregnancy between 28 and 30 weeks was supposed to be closely associated with the occurrence of preterm labor.Therefore,it is necessary to further approach the relationship and its clinical feasibility.
