Objective:

To assess the incidence of type 1 diabetes mellitus (T1DM) in children under 18 years of age in the northwest region of Turkey during 2013–2015.

Methods:

All newly diagnosed T1DM cases were recorded prospectively during 2013–2015. Total as well as gender and age group specific (0-4, 5-9, 10-14 and 15-17 age) mean incidences per 100.000 per year were calculated.

Results:

There were 1773 patients diagnosed during 2013-2015 (588 cases in 2013, 592 cases in 2014, 593 cases in 2015). Of these, 862 (48.6%) were girls and 911(51.4%) were boys. The mean age at diagnosis was 9.2±4.2 years and it was not significantly different between girls (9.0±4.1 years) and boys (9.4±4.4 years) (p=0.052). The crude mean incidence was 8.99/100.000 (95% CI: 8.58-9.42). Although mean incidence was similar between boys [8.98/100.000 (CI:8.40 to 9.58)] and girls [9.01/100.000 (CI:8.42 to 9.63)], there was male predominance in all groups except for 5-9 year age group. The standardized mean incidence was 9.02/100.000 according to the World Health Organization standard population. The mean incidence for the 0–4, 5–9, 10–14 and 15-17 age groups was 6.13, 11.68, 11.7 and 5.04/100.000 respectively. The incidence of T1DM was similar over the course of 3 years (p=0.95). A significant increase in proportion of diagnosis of cases was observed in the autumn– winter seasons.

Conclusion:

Northwest region of Turkey is having an intermediate incidence of T1DM.
