Gestational diabetes mellitus (GDM) is common during pregnancy. The World Health Organization (WHO) established criteria for the diagnosis of hyperglycemia in pregnancy (HIP) in 2013, which was endorsed by the Australasian Diabetes in Pregnancy Society (ADIPS). The HIP women with abnormal pregnancy oral glucose tolerance tests (POGTTs) were classified as belonging to the diabetes mellitus in pregnancy (DIP) group or GDM group. The present study aimed to investigate the prevalence of HIP over a 3-year period (2012 to 2015) with the new ADIPS (WHO) criteria in an ethnically representative Australian population based on samples obtained from public and private sectors.
