| Abstract | Objectives: To determine the correlation between the 50 gram glucose challenge test (50-g GCT)and neonatal birth weight.Materials and Methods: The study comprised of 1879 women who underwent 50-g GCT at 24-28weeks of gestation and delivered term infants. We determined the correlation between 50-gGCT by percentile and neonatal birth weight by using Pearson's correlation. ROC analysis wasused to determine the threshold of 50-g GCT for predicted low birth weight and macrosomiainfants.Results: The correlation coefficient between 50-g GCT by percentile and neonatal birth weight yieldeda result of 0.885 (strong positive correlation). Using ROC analysis, 50-g GCT level ? 130 mg/dlpredicted macrosomia infants with a sensitivity of 41%, specifiity 72%, positive predictive value(PPV) 2% and negative predictive value (NPV) 99%. 50-g GCT level ? 105 mg/dl predictedlow birth weight infants with a sensitivity of 40%, specifiity 65%, PPV 6% and NPV 95%respectively.Conclusion: There is a positive correlation between 50-g GCT and neonatal birth weight. 50-g GCTcan be used as predictor for macrosomia infants and low birth weight infants. |
