TEDDY - The Environmental Determinants of Diabetes in the Young

Completed

Conditions studied: Type 1 Diabetes Mellitus

In brief

The long-term goal of the TEDDY study is the identification of infectious agents, dietary factors, or other environmental agents, including psychosocial factors which trigger T1DM in genetically susceptible individuals or which protect against the disease. Identification of such factors will lead to a better understanding of disease pathogenesis and result in new strategies to prevent, delay or reverse T1DM.
