Is the evidence strong enough to change the diagnostic criteria for gestational diabetes now?

Abstract

The International Association of the Diabetes and Pregnancy Study Groups has proposed new thresholds for oral glucose tolerance tests that are based on the large observational Hyperglycemia and Adverse Pregnancy Outcomes study. By using these criteria about 18% of pregnant women will be diagnosed as having gestational diabetes mellitus. The question arises if we are ready for such an enormous increase in gestational diabetes mellitus patients, if outcome would really improve by using these criteria, and if additional studies are necessary before deciding on new diagnostic thresholds. In this clinical opinion, the pros and cons will be discussed.
