Introduction. The Australasian Diabetes in Pregnancy Society (ADIPS) has adopted the glucose levels for the diagnosis of GDM proposed by the International Association of Diabetes in Pregnancy Study Groups (IADPSG). This will result in an increased number of women being diagnosed with GDM. This will have work load implications and potentially other problems. This poster details the prevalence of GDM using an odds ratio (OR) of 2.0.
Methods. This was a post hoc analysis, applying an OR of 2.0, of a prospective study conducted to determine the prevalence of GDM using the IADPSG criteria. After a 75 g GTT, the diagnostic glucose levels with an OR of 2.0 were; fasting ≥5.3, one-hour ≥ 10.6 and two-hour ≥ 9.0 mmol/L.
Results. The prevalence of GDM was 5.6% for patients attending a public hospital, 8.4% for women attending a private practice pathologist and 7.1% overall. Whereas with an OR of 1.75, 57% of women would have been diagnosed with GDM on their fasting result, with an OR of 2.0, only 33.7% of women were diagnosed on the fasting result
Conclusion. Diagnosing GDM with an OR of 2.0 would result in a prevalence similar to that found with the old ADIPS criteria. This may be a discussion point for clinicians concerned about the higher number of women being diagnosed with the new criteria and the possible work load implications.
