TODAY2 Phase 2 Follow-up
|
Long-term Post-Intervention Follow-up of the TODAY Cohort (Treatment Options for Type 2 Diabetes in Youth and Adolescents)
|
The primary objective of T2P2 is to track the progression of T2D and related comorbidities and complications in the TODAY cohort as they transition to young adulthood. We hypothesize that:
- Youth-onset type 2 diabetes (T2D) will progress rapidly and result in high rates of diabetes-related medical complications and comorbidities.
- 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.

Plan Description: |
The TODAY/TODAY2 Study Group engages in a number of methods to disseminate and share resources.
- Findings are reported in manuscripts and presentations.
- An active Ancillary Studies Committee reviews proposals to access the study cohort, the central database, and stored biospecimens.
- Materials from the TODAY lifestyle intervention program and the standard diabetes education manual for adolescents developed by study experts are made available for public access on the website https://today.bsc.gwu.edu/web/today/home.
- The study group adheres to the policies of the NIDDK Central Repositories to make data available to other scientific investigators. A TODAY2 de-identified database will be prepared and transferred along with excess stored biospecimens. Appropriate informed consent is required to transfer stored biospecimens.
- TODAY establishes collaborative arrangements to work with other federally funded study groups.
