    Can the 50-g oral glucose tolerance test predict macrosomia and large for gestational age in pregnant women without gestational diabetes?
    (2021) Sahin, Erdem; Madendag, Yusuf
    Aim: The aim of the present study was to evaluate the relationship between the results of the 50-g oral glucose tolerance test (OGTT) and macrosomia and large for gestational age (LGA) in non-gestational diabetes mellitus (GDM) pregnant women. Materials and Methods: Our retrospective study comprised 980 pregnant women18–40 years old, within 24–28 weeks of gestation, and having a singleton pregnancy. GDM was screened using the 50-g OGTT. Patients were divided into three groups according to the OGTT results as follows: (1) 1-h plasma glucose levels >140 mg/dL and normal 100-g OGTT results (false-positive group), (2) 1-h plasma glucose levels between 130 and 139mg/dL, and (3) 1-h plasma glucose levels <130mg/dL. Results: Maternal characteristics were similar among the groups. Fetal weight was 3050±410g in the false-positive group, 3150±390g in the 130–139mg/dL group, and 3100±420g in the <130mg/dL group. Fetal weight was statistically similar among the groups (p= 0.910). Macrosomia was determined in 2 patients (1.25%) in the false-positive group, 3 (1.07%) in the 130–139mg/dL group, and 6 (1.1%) in the <130mg/dL group. These rates were statistically similar among the groups (p =0.175). LGA was determined in 21 patients (13.1%) in the false-positive group, 38 (13.5%) in the 130–139mg/dL group, and 70 (12.9%) in the <130mg/dL group. These rates were statistically similar among the groups (p = 0.450). Conclusion: Our results indicated that macrosomia and LGA rates were similar among groups and 50-g OGTT seems to have a low capacity for predicting macrosomia and LGA in pregnant women without GDM.

    Evaluation of exclusive breastfeeding rates and breastfeeding duration in term uncomplicated Turkish adolescent mothers
    (2020) Eraslan Sahin, Mefkure; Sahin, Erdem; Madendag, Yusuf; Col Madendag, Ilknur; Ak, Mehmet
    Aim: The aim of the present study was to evaluate exclusive breastfeeding (EBF) rates and breastfeeding duration in adolescent Turkish mothers after term-uncomplicated deliveries.Material and Methods: The study comprised 803 uncomplicated, nulliparous women, who had a single pregnancy and delivered at term gestational age. After excluding any maternal and fetal factors that affected early breastfeeding initiation, 674 nulliparous pregnant women were divided into three groups as follows: adolescents 16–17 years old, adolescents 18–19 years old, and non-adolescents 20–24 years old. The primary outcome of the study was defined as EBF of the infant, especially during the first 6 months of life. Results: Gestational age at delivery, birth weight, newborn gender, rate of induced labor, and rate of vaginal deliveries were similar among the groups. We found that 22.5% (14/62) of patients in the 16- to 17-year group, 41.8% (72/172) in 18- to 19-year group, and 72.9% (321/440) in the 20- to 24-year group had EBF during the first 6 months of their baby’s life. The rate of EBF during the first 6 months was significantly less in the 16- to 17-year and 18- to 19-year groups compared to that in the 20- to 24-year group (p0.001). The mean breastfeeding duration was 6.7±1.4months in the 16- to 17-year group, 9.5±2.2 months in the 18-to 19-year group, and 15.2±3.2 months in the 20-to 24-year group. Mean breastfeeding duration was significantly less in the 16-to 17-year and 18- to 19-year groups than in the 20- to 24-year group (p0.001).Conclusion: Our results indicated that adolescent pregnancy in Turkish populations is an important risk factor affecting both EBF during the first 6 months of life and breastfeeding duration.
