Recent trial results validate previous concerns about the IADPSG criteria for gestational diabetes

The definition of gestational diabetes mellitus (GDM) varies considerably depending on the region where a woman lives, and considerable controversy remains on the best approach to diagnosis. A 2021 trial showed no benefit for women or infants screened with the International Association of the Diabetes and Pregnancy Study Groups (IADPSG) one‐step criteria over the Carpenter–Coustan two‐step diagnostic criteria.1 The results of the trial validate the concerns expressed by several groups, including the Royal Australian College of General Practitioners (RACGP) and a National Institutes of Health consensus panel, over the introduction of the IADPSG criteria and should prompt an early review of the diagnostic criteria used in Australia.
