Abstract
Background: The aim of this study was to investigate long-term risk of type 2 diabetes (T2D) following a diagnosis of gestational diabetes and to identify factors that were associated with increased risk of T2D.
Methods: An observational cohort design was used, following up all women diagnosed with gestational diabetes mellitus (GDM) attending a Diabetes Antenatal Clinic in the Dundee and Angus region of Scotland between 1994 and 2004 for a subsequent diagnosis of T2D, as recorded on SCI-DC (a comprehensive diabetes clinical information system).
Results: There were 164 women in the study who were followed up until 2012. One quarter developed T2D after a pregnancy with GDM in a mean time period of around eight years. Factors associated with a higher risk of developing T2D after GDM were increased weight during pregnancy, use of insulin during pregnancy, higher glycated haemoglobin (HbA1c) levels at diagnosis of GDM, and fasting blood glucose.
Conclusions: These findings suggest there is a viable time window to prevent progression from GDM to T2D and highlights those women who are at the greatest risk and should therefore be prioritised for preventative intervention.
