Trends in the incidence of childhood-onset type 1 diabetes in Slovakia 1985 - 2000.

The aim of this work was to study and monitor the patterns in incidence of childhood type 1 diabetes in Slovakia. The incidence of type 1 diabetes per 100,000/year from 1985 to 2000 was determined in children 0 - 14 years old. A total of 1,818 cases were diagnosed during this time. Poisson regression models were used to study incidence trends. The overall incidence of type 1 diabetes varied from 5.62/100,000 per year in year 1986 to 14.46/100,000 in year 1998. This represents a 2.57-fold increase. The incidence increased with age and was the highest among children 10 - 14 years of age. The incidence of type 1 diabetes in Slovakia is increasing very dramatically, especially in age group 0 - 4 years.
