The Finnish Pediatric Diabetes Register

The Finnish Pediatric Diabetes Register and sample collection is an ongoing study all over Finland. We recruit children and adolescents with newly diagnosed diabetes (all forms of diabetes, not only type 1 diabetes) and his/her family members.

The Diabetes Register is collecting information on the family history of diabetes, and the clinical status and metabolic decompensation of newly diagnosed patients at the time of diagnosis. Most of the families participating in the register provide also blood samples. Only a one-time blood sample is taken. Please contact  the doctor or diabetes nurse taking care of the child or adolescent with newly diagnosed diabetes in your family to join the Register or contact directly the Register Nurse Sirpa Nolvi, e-mail: or tel +358 50 427 0564.
