There are a number of genes linked to type 1 diabetes (T1D), but not everyone with genetic predisposition develops the condition. This suggests that there are likely environmental triggers that stimulate the development of T1D. The Environmental Determinants of Diabetes in the Young (TEDDY), a study part supported by JDRF, is a large prospective, longitudinal cohort study investigating the environmental factors that may contribute to T1D development.
An article published by the TEDDY study group in Paediatric Diabetes this month highlights the benefits of early diagnosis of children at risk of T1D. Children involved in TEDDY are from six large clinical centres across the US and Europe and are being followed from birth until 15 years of age to track diet, illness, body growth and other life experiences.
