Type 1 diabetes is generally believed to be be the result of an immune destruction of pancreatic β-cells in genetically susceptible individuals exposed to environmental risk factors. To study the epidemiology of childhood-onset type 1 diabetes mellitus in Europe, the EURODIAB collaborative group established in 1988 prospective geographically-defined registers of new cases diagnosed under 15 years of age. The 10-year-old study shows a greater than 10-fold range in incidence rate of childhood diabetes in Europe. The standardised average annual incidence rate during the period 1989-1998 ranged from 3,6 cases per 100000 per year in Macedonia to 43,9 cases per 100000 per year in Finland. Combined data from all centres indicates that the annual rate of increase in incidence was 3,2% but in some central and eastern European countries it was higher. The age-group-specific rates of increase were 5% for children aged 0-4 years, 3,7% for 5-9 years, and 2,1% for 10-14 years, which shows that the highest rates of increase occurred in the youngest age group. The Hungarian Childhood Diabetes Registry has collected the data of all newly diagnosed children with type 1 diabetes aged 0-14 years since 1st January 1978. The standardised incidence rate during the period 1978-2002 was 8,6 cases per 100000 per year, the lowest in the youngest (0-4 yr), highest in the 10-14-year-old-children. There was a linear increasing trend in incidence with the average rate of annual increase of 5,1%. Comparing our incidence rate with other European countries Hungary belongs to the medium-risk countries with similar age- and sex-specific incidence rates. The results of the EURODIAB study confirm a very wide range of incidence rates of childhood type 1 diabetes within Europe and show that the increase in incidence varies from country to country. Such variation seems to be unlikely to be explained by genetic differences, since Europeans (except some small populations) are more homogeneous compared with other populations of other continents. The rapid increase in incidence may be explained by changes in environmental factors.
