The Role of Untimed Blood Glucose in Screening for Gestational Diabetes Mellitus in a High Prevalent Diabetic Population

الملخص EN

Global prevalence increase of diabetes type 2 and gestational diabetes (GDM) has led to increased awareness and screening of pregnant women for GDM.

Ideally screening for GDM should be done by an oral glucose tolerance test (oGTT), which is laborious and time consuming.

A randomized glucose test incorporated with anthropomorphic characteristics may be an appropriate cost-effective combined clinical and biochemical screening protocol for clinical practice as well as cutting down on oGTTs.

A retrospective observational study was performed on a randomized sample of pregnant women who required an OGTT during their pregnancy.

Biochemical and anthropomorphic data along with obstetric outcomes were statistically analyzed.

Backward stepwise logistic regression and receiver operating characteristics curves were used to obtain a suitable predictor for GDM without an oGTT and formulate a screening protocol.

Significant GDM predictive variables were fasting blood glucose ( p = 0.0001 ) and random blood glucose ( p = 0.012 ).

Different RBG and FBG cutoff points with anthropomorphic characteristics were compared to carbohydrate metabolic status to diagnose GDM without oGTT, leading to a screening protocol.

A screening protocol incorporating IADPSG diagnostic criteria, BMI, and different RBG and FBG criteria would help predict GDM among high-risk populations earlier and reduce the need for oGTT test.
