Progression rate of Gestational Diabetes Mellitus (GDM) to Type 2 Diabetes Mellitus (DM2) 6 weeks to 28 years post-partum varies from 2.8% - 70% in different studies consisting of different ethnic population1. The data about such progression rate in North Queensland region where population density of indigenous Australians is high are lacking2,3. Indigenous population in this region has higher incidence of Diabetes including Diabetes in Pregnancy (DIP) and related complications3. We undertook a retrospective study of 167 GDM mothers who delivered at the Cairns Base Hospital in 2004 to identify their progression rate to Type 2 Diabetes Mellitus (DM2) in seven years. We systematically reviewed the follow up Glucose Tolerance Test (GTT) and HbA1c results. We identified that there has been a significant lack in follow up of those patients. Only 7 (4%) mothers had a follow up test within 8 weeks post-partum. Another 60 mothers had follow up tests in the subsequent years. Of these 67 mothers 19 (36.5%) progressed to DM2. These results initiated us to do the second phase of the study to complete their follow up by performing GTT in 2012. This follow up study is nearing completion and results will be available for discussion before the ADS meeting
