AbstractGestational diabetes mellitus (GDM) is a condition that is very common during pregnancy and has negative consequences for both mother and fetus. Insulin resistance has been shown as an important cause in the pathogenesis of GDM and low-level inflammation is suggested to be one of the underlying causes of insulin resistance. We aimed to investigate whether the neutrophil-lymphocyte ratio (NLR), which is an indicator of systemic inflammation, is a predictor for GDM. A total of 228 pregnant women, including 128 GDM (patient group) and 100 healthy pregnant were included in the study. GDM was diagnosed with a 1-step approach between 24 and 28 weeks of pregnancy. We found a significant increase in NLR in the 1st and 3rd trimesters in the GDM group compared to healthy pregnant women, which supports that systemic inflammation starts in the early stages of pregnancy and continues throughout pregnancy. We also reported a positive correlation between NLR and fasting plasma glucose and body mass index in both trimesters. We showed that first trimester NLR independently predicted the development of GDM.Copyright © 2022 the Author(s). Published by Wolters Kluwer Health, Inc.
