The oral glucose tolerance test is the gold standard for diagnosing gestational diabetes mellitus. Nevertheless, the oral glucose tolerance test is time-consuming and requires patient preparation. On the contrary, Glycated albumin does not require patient preparation or administration of any substance. Most studies on glycated albumin in pregnancy were among the non-African population, and black Americans have higher glycated albumin levels than Caucasians. This study determined the use of glycated albumin in diagnosing gestational diabetes mellitus among pregnant women. The study was a prospective study of 160 pregnant women between 24 and 28 weeks of gestation at the University of Port Harcourt Teaching Hospital. The diagnosis of gestational diabetes mellitus was based on the World Health Organization 2013 criteria. The diagnostic value of glycated albumin was determined using the area under the receiver operator characteristic curve. The prevalence of gestational diabetes mellitus was 9.4% and the mean glycated albumin was 16.91% (±2.77). The area under the receiver operator characteristic curve for glycated albumin was 0.845 (95% CI 0.733 - 0.956;p = 0.0001). The optimal cut-off value of glycated albumin in the diagnosis of gestational diabetes mellitus was 18.9%. Glycated albumin was useful in the diagnosis of gestational diabetes mellitus at 24 to 28 weeks of gestation.展开更多

However, the relationships between them remain ambiguous. This study aimed to analyze the effect of different oral glucose tolerance test （OGTT） results on adverse perinatal outcomes. Methods： This retrospective cohort study included data from 15 hospitals in Beijing from June 20, 2013 to November 30, 2013. Women with gestational diabetes mellitus （GDM） were categorized according to the number and distribution of abnormal OGTT values, and the characteristics of adverse pregnancy outcomes were evaluated. Chi-square test and logistic regression analysis were used to determine the associations. Results： in total, 14,741 pregnant women were included in the study population, 2927 （19.86%） of whom had G DM. As the number of hyperglycemic values in the OGTT increased, the risk of cesarean delivery, preterm births, large-for-gestational age （LGA）, macrosomia, and neonatal complications significantly increased. Fasting hyperglycemia bad clear associations with macrosomia （odds ratios [ORs]：1.84, 95% confidence intervals [CIs]： 1.39-2.42, P 〈 0.001）, L（SA （OR： 1.70, 95% CI： 1.29-2.25. P 〈 0.001）, and cesarean delivery （OR： 1.33, 95% CI： 1.15-1.55, P 〈 0.001）. The associations were stronger as tasting glucose increased. GDM diagnosed by hyperglycemia at OGTT-2 h was more likely to lead to preterm birth （OR： 1.50, 95% Cl： 1. 11-2.03, P 〈 0.01）. Conclusions： Various characteristics of OGTTs are associated with different adverse outcomes. A careful reconsideration ofGDM wiih hierarchical and individualized management according to OGTT characteristics is needed.展开更多
