Introduction: Preterm labor is one of the most important pregnancy problems that cause the majority of infant mortality and morbidity even in advanced societies, and it may be possible to improve the outcome of pregnancy by predicting it. The present study was conducted with aim to evaluate the predictive value of the first and the third trimester maternal mean platelet volume (MPV) for prediction of preterm labor. Methods: This prospective cohort study was performed in 2019-2021 on 400 pregnant women with a gestational age of 9-12 weeks in Akbarabadi Hospital, Tehran. According to the inclusion and exclusion criteria of the study, blood sample was taken to check the mean volume of platelets in the first trimester and again in the gestational age of 26-28 weeks and the mothers were monitored up to delivery. At the end, the incidence of preterm delivery was determined and the mean volume of platelets (MPV) in the first and third trimesters of pregnancy were investigated and compared in two groups of preterm delivery and term delivery. In order to determine the accuracy, the ROC curve was drawn and the area under the curve was calculated. P<0.05 was considered significant. Results: Out of 400 studied women, 365 finished the study and were evaluated, and 96 women (26.3%) had preterm labor. MPV of the first trimester did not show significant difference between the two groups of preterm delivery and natural delivery (9.68±1.09 vs 9.57±1.14, p= 0.430). Also, MPV of the third trimester was not significantly different between the two groups of preterm delivery and natural delivery (9.62±1.12 vs 9.46±1.19, p= 0.251). The ROC curve was used to determine the accuracy of mean platelet volume in order to diagnose preterm delivery that considering to the area under the ROC curve as 0.50, it showed no predictive value for preterm labor. Conclusion: The MPV cannot be considered as a suitable index for prediction of preterm labor. [ABSTRACT FROM AUTHOR] |
