Historical and statistical aspects of risk groups analysis and testing in the context of gestational diabetes mellitus

Abstract

In order to enhance cost-benefit value of the gestational diabetes mellitus screening (GDM) the concept of universal screening i.e., screening of all pregnant women for gestational diabetes, has mostly been abandoned in favor of the concept of selective screening. Selective screening implies that only women with risk factors are being screened for GDM. However, some recent studies have shown that with the application of the selective screening approach, some women with GDM may not receive proper and timely diagnosis. This review addresses the pros and cons of both concepts. It will also discuss screening methods and methods of preparation and performance of oral glucose tolerance test (OGTT) and the interpretation of its results.
