Gestational diabetes rates to rise with new diagnostic criteria

THE prevalence of gestational diabetes looks set to increase if new diagnostic guidelines proposed by the International Association of Diabetes and Pregnancy Study Groups (IADPSG) are adopted, an MJA study says.

The IADPSG, formed following the results of the 2008 Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study, recommended a fasting plasma glucose level of ≥ 5.1 mmol/L or a two-hour level of ≥ 8.5 mmol/L.

The Australasian Diabetes in Pregnancy Society (ADIPS) guidelines, widely used for 20 years, recommend a fasting plasma glucose level of ≥ 5.5 mmol/L or a two-hour level of ≥ 8.0 mmol/L.

The proposed criteria would increase the prevalence of gestational diabetes from 9.6% to 13%, the NSW researchers found.

Concerns about increased obstetric and neonatal intervention, resource allocation and increased workload needed to be weighed up against the new criteria’s strong evidence base for outcomes, the researchers
