  • 5,470 patients with gestational diabetes and 783 control subjects


  • A study of participants who presented for postnatal follow-up between 1971 and 2003.


  • Risk of developing diabetes increased with time for both groups and was 9.6 times greater for patients with GDM.
  • The cumulative risk of developing type 2 diabetes for the GDM patients was 25.8% at 15 years post-diagnosis.
  • Predictive factors for the development of type 2 diabetes were use of insulin (hazard ratio x3.5), Asian origin compared with Caucasian (x2.1), and 1-h blood glucose (x1.3 for every 1 mmol increase above 10.1 mmol).
  • BMI was associated with an increased risk of developing type 2 diabetes.
