Key Points

To investigate demographic changes in the adult population with type 1 diabetes and their association with comorbidities and mortality.
Analyzed data from the Finnish Diabetes Control Study (FinDiCon)
Monitored insulin pump therapy usage and ketoacidosis rates
Evaluated changes in HbA1c and LDL-c levels over the study period
Assessed comorbidities and mortality rates in the population
Increased proportion of elderly individuals with type 1 diabetes
Stable rates of diabetes-specific comorbidities
Improved HbA1c and LDL-c levels observed during the study
No increase in ketoacidosis incidence despite rising insulin pump therapy usage

Implication

Analysis shows demographic shifts and mortality factors in type 1 diabetes adults, suggesting improved outcomes.

Abstract

The proportion of elderly with T1D is increasing, with no concomitant increase in vascular events. Insulin pump therapy has become more common without a concomitant increase in ketoacidosis incidence. HbA1c and LDL-c levels improved during the study. Finnish data indicate a shift in T1D demographics, characterised by improved survival, while rates of diabetes-specific comorbidities remain stable.
