Analysis of the dynamics of mortality from respiratory diseases in the Russian Federation for 2019-2020

Aim. To study the dynamics and contribution of mortality from Diseases of the respiratory system (DRS) in 2019 and 2020 to mortality from all causes with and without deaths from COVID-19 in 82 regions of the Russian Federation. Materials and methods. The data provided by Rosstat for 2019 and 2020 on the average annual population and the number of deaths due to causes of DRS (class J00-J99) were used the standardised death rate (SDR) were calculated, the regional average value, standard deviation and coefficient of variation. Results. The average increase in the SDR from DRS in 2020 was 22.19 +/- 13.22 per 100 thousand population (66.44 +/- 89.6% higher than in 2019). The average regional SDR from DRS + COVID-19 in 2020 was higher than the SDR from DRS in 2019 by 87.65 +/- 30.1 per 100 thousand population. The average regional share of SDR in the structure of mortality excluding COVID-19 increased from 3.66 +/- 1.44 to 5.06 +/- 2.49%; taking into account COVID-19, it increased to 10.96 +/- 3.13%. In 16 regions, the SDR from DRS + COVID-19 exceeded the increase in mortality from all causes. No correlation was found between SDR (2020) from all causes and SDR from COVID-19 (r=0.09; p=0.39); an inverse correlation was found between SDR from DRS and SDR from COVID-19 in 2020 (r=-0.42; p<0.0001). Conclusion. Against the background of high interregional variability of SDR from DRS in most regions, an increase in the mortality rate from DRS and the contribution of DRS to total mortality in 2020 was registered.
