THE RISK MORTALITY OF THE POPULATION OF AZERBAIJAN FROM CIRCULATORY DISEASES, DEPENDING ON THE SEASON A. J. Rzayeva, K. F. Agayeva, E. M. Hatamzada, A. K. Mammadbayli Azerbaijan State Advanced Training Institute for doctors named after A. Aliyev, Baku ABSTRACT The Objective. To obtain evidence-based data about the role of seasons of the year in the formation of the population mortality risk from the circulatory system diseases (CSD) in Azerbaijan and its regions with specific climate. Materials of the study. A case of mortality was a unit of statistical observation. The fatalities from all reasons, including CSD have been distributed by the days of every month in the year. Daily average amount of fatalities by months and seasons ( from 20 December to 19 March – winter; from 20 March to 19 June- spring; from 20 June to 16 September; from 20 September to 19 December - autumn) have been determined. Results. In Azerbaijan the risk of general mortality and mortality from CSD is the highest in winter, it decreases in spring but nonuniformly (the general mortality rate is less than that from CSD). That is why the share of CSD increases among mortality reasons. Conclusions. Seasonal change of mortality risks from CSD is multivariant. Winter-spring increase of risk predominates in Azerbaijan. In some regions of Azerbaijan the mortality risk from CSD increases only once either in spring or in summer or winter. Key words: seasonal dynamics, risk of mortality, circulatory system diseases.
