Evaluation of relationship between maternal Hemoglobin concentration at the first trimester and occurrence of GDM

Early diagnose and management of GDM can decrease perinatal, neonatal and long-time infant problems. There is now accumulated evidence in the literature that high maternal Hemoglobin is associated with increased incidence of adverse pregnancy outcomes which include low birth weight and preterm labor. In the no pregnant population, an association between hemoglobin concentrations with Diabetes Mellitus has been reported before. We decided that we study relationship between maternal Hemoglobin concentration at the first trimester and occurrence of GDM. In a retrospective study sample comprised 100 women. Age, weight, parity, Hemoglobin concentration and FBS at the initial antenatal visit and GCT during 24-28 weeks are recorded. In this study 36 women had GDM and the rest were health. Age, parity and Hemoglobin concentration emerged to be significant factors in incidence of GDM. High maternal Hemoglobin (more than 13 g/dl) at the initial pregnant visit (the first 14 week) is an independent risk factor for GDM.
