Abstract

The purpose of the study is comparative assessment of type 2 diabetes mellitus incidence rate among population of cities of the Republic of Azerbaijan. Study was carried out in main cities of republican subordination. The unit of statistical observation was a patient with confirmed and newly diagnosed T2DM. Standardised incidence rate of T2DM by age was calculated by direct standardisation method. Variability of incidence rate of Azerbaijan population was estimated. The highest incidence for 2012 year was identified among population of Naftalan and the lowest – in the city of Ganja. As the result of comparison significant difference between cities Sumgayit, Shirvan and Mingachevir was not determined (р>0.05). In these cities the incidence rate is much higher (р<0.01) than in Ganja, lower than in Baku and Naftalan. The intercity difference in the standardised incidence rate of the population with T2DM remains. But at the same time volatility of standardised T2DM incidence rate (151.6) among population nearly is the same of actual incidence rate (151.3). The population risk of T2DM in cities of Azerbaijan differs from each other significantly, both due to actual and standardised coefficients. Variability of incidence rate of T2DM among population more pronounced according annual coefficients, than according average chronological coefficients and standard deviations. Volatility of incidence rate of T2DM among population can be comprehensively assessed by the level of annual, chronological average incidence rates, variability, and the size of the standard deviation.
