To the Editor: It is with great interest that we read the recent publication in Diabetologia entitled ‘New diagnostic criteria for gestational diabetes mellitus and their impact on the number of diagnoses and pregnancy outcomes’ [1], in which Koning et al address the contentious recent change in diagnostic criteria for gestational diabetes mellitus (GDM). In evaluating the impact of the WHO 2013 criteria compared with the WHO 1999 criteria, they identified that women diagnosed with GDM based on the new, lower fasting blood glucose criteria of 5.1–6.9 mmol/l had an increased risk of adverse outcomes if not treated, as compared with women with normal glucose tolerance. Hence, they concluded that the lower fasting blood glucose level criteria of ≥5.1 mmol/l is justified and should be adopted in the Netherlands, where their study was carried out. Following on from this, Koning et al expressed concern about relaxing the 2 h plasma glucose (2HG) criteria for GDM, suggesting further studies...
