Objective: To document the incidence of type 1 diabetes mellitus in Lithuanian 1539 years of age population from 1991 to 2012.
Research design and methods: A specifically developed contact system with all endocrinologists and diabetologists and general practitioners involved in the diabetes care covering 100% of the Lithuanian population aged 1539, was the initial data source. Annual reports from regional family physicians, endocrinologists and diabetologists, statistical note-marks of diabetic patients who visited Medical Units, death certificates and patients lists from Diabetes Societies remained as secondary independent sources for case ascertainment.
Results: The total of 1,511 new cases (789 males and 722 females) of type 1 diabetes mellitus were recorded among the population 1539-year of age during the period 1 January 199131 December 2012. The cumulative incidence density per year was 8.40/100,000 (95% Poisson distribution confidence interval 8.068.75) and was slightly higher among males (10.98/100,000, 95% CI 10.4411.54) than among females (5.79/100,000, 95% CI 5.406.21), P<0.0001. Age standardized and age adjusted overall incidence rates for males and females were 10.99 and 5.81, respectively. Male/female ratio was 1.92. Results of the linear regression models showed that the incidence density of type 1 diabetes mellitus in 1539-year age group had very slow tendency to decrease.
Conclusions: The results suggest that the incidence data of type 1 diabetes mellitus in Lithuania in 1539-year-aged group is lower than in other countries of Baltic Sea region. The data contributes to the knowledge of the incidence of type 1 diabetes mellitus in Eastern Baltic countries, an area that until now has been lacking epidemiological data on diabetes among 1539-year aged population.
