Annual incidence of type 1 diabetes in Québec between 1989-2000 in children.
OBJECTIVE
To document the number of new pediatric cases of type 1 diabetes diagnosed each year, from 1989 to 2000, in the province of Québec. To analyze secular trends and age of presentation during the same period.


METHODS
Data, gathered through a government allocation program, provided the number of reported new cases. The data bank also made available the age at diagnosis, sex and geographic distribution of cases.


RESULTS
A steady number of new cases, approximately 240 p.a., was diagnosed over the 12-years. The annual incidence in the pediatric population of Québec was 15 per 100,000. There was no trend towards earlier age at diagnosis.


CONCLUSIONS
We found no evidence of increase in the number of children diagnosed with type 1 diabetes in Québec between 1989-2000. Also, over the same period, the data did not support a younger age at diagnosis.
