The aim of this study was to investigate epidemiological patterns of childhood type 1 diabetes in Newfoundland and Labrador, Canada. This study includes type 1 diabetes mellitus subjects among children aged 0-19 years in Newfoundland and Labrador during seven years (April 1995 to March 2002). Data was obtained from the provincial hospital database. A total of 894 type 1 diabetes-related hospitalizations were identified, representing a hospitalization rate of 88.6 per 100,000 person-years (P-Y). The overall hospitalization rate increased from 84.5 per 100,000 in 1995 to 103.8 per 100,000 in 2002 (P = 0.065). Hospitalization rates for females and males were 100.2 and 77.3 per 100,000 P-Y, respectively (P = 0.00011). Of the 894 hospitalizations, 216 hospitalizations were for diabetic ketoacidosis (DKA) (21.4 per 100,000). Also, a 71% increase in DKA hospitalizations among children aged 15-19 years was found over the study period (P = 0.006). Diabetic ketoacidosis hospitalizations among females was significantly higher than males (P = 0.000005). Female gender and older age were found to be predictive risk factors of DKA. The incidence rate of type 1 diabetes among children aged 0-7 years was 23.8 per 100,000 P-Y; incidence rates for males and females were 27.7 and 19.6 per 100,000 P-Y, respectively (P = 0.15). In conclusion, Newfoundland and Labrador has the highest incidence rates of type 1 diabetes mellitus in North America. Hospitalization rates for DKA and non-DKA have not decreased since 1995/96. Age and sex patterns suggest that DKA is a particular challenge among adolescent girls.
