The incidence of Type 1 diabetes in 2417 children aged 0-14 years was studied between 1978 and 1997. Statistical analysis of the data in the twenty-year period showed a steady increase in incidence of Type 1 diabetes with an average rate of 4.8% (95% CI 4.0-5.5) per annum. The incidence rate was lowest in children aged 0 to 4 years and the highest in the age group 10 to 14 years. This increase in incidence was similar for all age groups, but it was most pronounced in the 10 to 14 year-old age group. One hundred and twenty one of the 1239 families (9.7%), one of parents was also reported to have Type 1 diabetes and in 3 (0.2%) families both parents had Type 1 diabetes. Twenty two (2.3%) of the diabetic families had a sibling with Type 1 diabetes. The nearly three-fold increase in incidence during the last two decades (3.8 per 100,000 per year in 1978; 10.7 per 100,000 per year) was probably due to environmental factors, while the high degree of familial clustering emphasises the role of genetic factors in the etiology of Type 1 diabetes.
