TEDDY: continued follow-up and a new case-control group for young-onset diabetes

Limited Competition: Continued Follow-up of Subjects and Initiation of a Second Case-control Cohort in The Environmental Determinants of Diabetes in The Young Study (TEDDY)

NIH-funded research University of South Florida · NIH-11388703

This project continues long-term tracking of children at risk for early-onset (type 1) diabetes and adds a new matched group to learn what environmental differences exist between those who develop diabetes and those who do not.

What this research studies

If you or your child are in TEDDY, the team will keep collecting health information, blood samples, and tests for diabetes-related autoantibodies over time. The Data Coordinating Center at the University of South Florida will manage and protect your data, monitor data quality across sites, and provide statistical support. A second nested case-control cohort will match children who develop diabetes with similar children who do not to look for environmental and other differences. Researchers will share findings, study materials, and communications with participants and may use results to guide earlier detection or prevention strategies.

Who could benefit from this research

Good fit: Ideal candidates are children already enrolled in TEDDY or those at genetic risk for early-onset type 1 diabetes who can continue regular follow-up and provide periodic samples.

Not a fit: Adults without childhood-onset type 1 diabetes, people not enrolled at a TEDDY clinical center, and those needing immediate treatment rather than long-term follow-up are unlikely to benefit directly.

Why it matters

Potential benefit: Could help identify environmental or early biological markers of type 1 diabetes that lead to better prevention or earlier diagnosis for children.

How similar studies have performed: Previous long-term cohort work, including earlier TEDDY results, has identified autoantibodies and possible environmental links, and this project builds on that track record by adding a focused case-control comparison.
