“…Gestational diabetes mellitus (GDM), traditionally defined as any degree of glucose intolerance with onset or first recognition during pregnancy, is one of the most common medical complications of pregnancy. The estimated global prevalence of hyperglycaemia in pregnancy (including GDM, and ‘total diabetes’ (known/unknown pre‐existing diabetes)) is 16.9%; recent Australian GDM prevalence estimates range from 9.6 to 16.0% depending on the diagnostic criteria used …”

An increase in 'common' outcomes (those pre-specified by ≥ 50% of the protocols and reviews) over time was observed (2001-09: 27 vs. 2010-14: 46). There were discrepancies in outcomes pre-specified in reviews and reported by randomised trials. Efforts are needed to develop a core outcome set, to reduce research waste and improve health outcomes.

“…Application of the IADPSG criteria increased GDM diagnosis by 30% in our cohort, where women meeting IADPSG‐only criteria ( n = 958) did so by introduction of the one hour glucose threshold (55%) and lowering of the fasting threshold (32%). A study in Western Australia reported a 20% increase in diagnosis in a predominantly Caucasian cohort . In the United States, transition from Carpenter–Coustan criteria to one‐step screening and a single abnormal value on IADPSG criteria have significantly increased diagnosis .…”

“…Studies have reported varied perinatal outcomes in untreated women meeting IADPSG criteria compared to women without GDM. A United States cohort with a large African‐American contingent found increased fetal overgrowth, a Canadian study found no difference, a New Zealand study (55% Maori or Pacific Islander) found increased birthweight and induction, and a Western Australia study (predominantly Caucasian women) reported increased birthweight and macrosomia . Compared to the aforementioned studies, in our larger multicultural cohort with adjustment for confounders including BMI and region of birth, we found that IADPSG‐only criteria identified women and babies with increased risk of gestational hypertension, caesarean section, LGA and shoulder dystocia.…”

“…GDM was diagnosed using a two‐step screening process, which may have missed some women identified using a one‐step process as recommended by IADPSG. However, this is common to most retrospective studies examining IADPSG criteria in this context …”

“…The Australasian Diabetes in Pregnancy Society (ADIPS) have endorsed the IADPSG criteria, yet national implementation has been patchy and they remain controversial . This is the second Australian study examining pregnancy outcomes with the IADPSG criteria . In a multiethnic cohort with high prevalence of GDM diagnosed by ADIPS 1998 criteria, we examined maternal characteristics and perinatal outcomes in additional women meeting IADPSG criteria compared to women without GDM.…”

The IADPSG diagnostic criteria identify women with increased risk of adverse pregnancy outcomes in Victoria

Controversy remains surrounding International Association of Diabetes and Pregnancy Study Group (IADPSG) diagnostic criteria for gestational diabetes mellitus (GDM), including perceived improvement in perinatal outcomes and health service implications. We compared perinatal outcomes for untreated women meeting IADPSG-only criteria and women without GDM in Victoria. Women meeting IADPSG-only criteria were characterised according to fasting and one hour glucose thresholds and by region of birth. IADPSG criteria identified women with increased risk of adverse perinatal outcomes, particularly women born in Australia compared to Asian regions.

Quantify the proportional increase in gestational diabetes (GDM) prevalence when implementing the new International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria compared to prior GDM criteria, and to assess risk factors that might affect the change in prevalence. Methods: A systematic review and meta-analysis was performed of cohort and crosssectional studies between January 1, 2010 to December 31, 2018 among pregnant women with GDM using IADPSG criteria compared to, and stratified by, old GDM criteria. Web of science, PubMed, EMBASE, Cochrane, Open Grey and Grey literature reports were included.The relative risk for each study was calculated. Subgroup analyses were performed by maternal age, body mass index, study design, country of publication, screening method, sampling method and data stratified according to diagnostic criteria. Results: Thirty-one cohort and cross-sectional studies with 136 705 women were included.Implementing the IADPSG criteria was associated with a 75% (RR 1.75, 95% CI 1.53-2.01) increase in number of women with GDM with evidence of heterogeneity. Conclusions: The IADPSG criteria increase the prevalence of GDM, but allow movement towards more homogeneity. More studies are needed of the benefits, harms, psychological effects and health costs of implementing the IADPSG criteria.
