Numerous trials have shown the efficacy of various interventions to prevent type 2 diabetes in high-risk populations [10–13]. However, the focus for these trials was high-risk patients identified according to impaired fasting glucose (IFG) or impaired glucose tolerance (IGT). There is limited—albeit generally positive—evidence of the efficacy of these interventions among other high-risk groups, including those with prior GDM [14]. Available data support three main modalities of in- tervention: breastfeeding, lifestyle modification, and pharmacological treatment [15].
