Morbidity dynamics of type 1 diabetes mellitus in different administrative territorial units of Azerbaijan Republic in 2012-2016

Aim. To assess the dynamics of population’s morbidity of type 1 diabetes in different autonomous territorial units of Azerbaijan Republic. Methods. The unit of observation was a case of type 1 diabetes newly diagnosed during the calendar year. For each administrative territorial unit of Azerbaijan Republic based on the data about quantity of patients with type 1 diabetes and population, morbidity rate per 100 000 of average annual population and average error for calendar years were calculated. Results. At the beginning of observation (2012) morbidity rate of type 1 diabetes among Azerbaijan population was 54.5±0.76 per 100 000. In different administrative territorial units this indicator ranged between 2.0±1.41 and 294.8±12.0 per 100 000. Relatively low rate of type 1 diabetes was identified in Mingachevir town (2.0±1.41), Masalli (6.1±1.7), Jalilabad (5.8±1.68), Imishli (5.7±2.17), Sheki (4.5±2.17), Gusar (2.2±1.52) regions and Absheron (5.0±1.57 per 100 000). The highest morbidity rate in 2012 was observed in Shamkir (294.8±12.0), Khachmaz (278.7±12.82) and Sabirabad (236.6±11.9 per 100 000). The main trend of difference is a linear decrease of the morbidity rate, which is well explained by linear regression equation (Y=-9.078х+61.1; R2=0.95). In Azerbaijan the average morbidity rate of type 1 diabetes in 2012-2016 was 33.2±0.58 per 100 000, there are administrative territorial units with low (60 per 100 000 in Shirvan city, Sabirabad, Shamkir, Khachmaz districts). Conclusion. Morbidity rate of type 1 diabetes was different in different calendar years, ratios of the highest and lowest annual morbidity rate in Azerbaijan (3.5) and in separate administrative territorial units (4.2 in Baku, 23.9 in Ganja, 90.0 in Mingechevir, etc.) are different.
