In this follow-up study to the TODAY clinical trial, T2P2 will evaluate the rates of comorbidities and complications in the TODAY cohort and will compare with rates for children with type 1 diabetes with a similar age of onset and with adult-onset type 2 diabetes. Two hypotheses will be tested: (1) youth-onset T2D will progress rapidly and result in high rates of diabetes-related medical complications and comorbidities and (2) the rapid rate of progression is related to increased insulin resistance characteristic of puberty, worse β-cell function, degree of glycemic control, control of non-glycemic factors, and obesity itself.

TODAY2 is the long term follow-up of the youth from TODAY, to track the progression of type 2 diabetes (T2D) and related comorbidities and complications in the TODAY cohort as they transition to young adulthood.
TODAY found that metformin plus rosiglitazone was more effective than metformin alone with metformin plus lifestyle having an intermediate effect resulting in more aggressive treatment in clinical practice
