Increased risk of childhood type 1 diabetes in children born after 1985.

Objective: The incidence rate of childhood type 1 diabetes is thought to be increasing; however, Danish studies have not confirmed this. Using a national diabetes register initiated in 1996 and two previous regional incidence studies, we studied the age-specific incidence of type 1 diabetes over 30 years. Here, we describe the incidence rates of type 1 diabetes in Danish children from 1996 to 2000 and evaluate trends in age-specific incidence rates from 1970 to 2000.

Incidence of insulin-dependent diabetes mellitus in age groups over 30 years in Denmark.

The incidence of IDDM in the age group over 30 years was estimated in a historical prospective study, using clinical and biochemical measurements at onset as criteria for classification. The study population, nearly one million, represents 20% of the Danish population. The degree of ascertainment was > 99%.

Present and projected consumption of hospital bed-days as a function of terminal days before death.

In 1983 the bed-day consumption per year per 1,000 inhabitants was 1,571 for all subjects in the Copenhagen County, and 774, 1,239, and 4,918 for subjects 0-19 years, 20-64 years, and above 65 years of age, respectively. Extrapolating from these data the hospital bed-day consumption per inhabitant is predicted to increase by 20.6% in Denmark by the year 2025 as compared to 1986.
