INTRA-ANNUAL DYNAMICS OF MORTALITY RATES IN CITIES OF THE SOUTHERN PART OF THE RUSSIAN FAR EAST

Abstract

The analysis of the intra-annual dynamics of mortality rates features from all causes and from cardiorespiratory diseases, using the seasonality index, showed the maximum mortality rate in cities of the Far East south in winter, and the minimum-in summer.

A detailed analysis of mortality caused by cardiorespiratory diseases in the older age cohort has revealed a higher risk of pathologies in winter periods, with a maximum in February.

A relative indicator decline in November, apparently associated with the so-called «harvest effect», when excess mortality in one period (in October) is compensated by the indicator decrease in the subsequent time period. For the elderly population in Khabarovsk, the maximum death rate in January and its sharp rise in October repeats the picture of all-cause mortality with little gender difference.

For men – residents of Vladivostok-the maximum development of cardiovascular disasters occurs in January, a slight increase in mortality is observed in May and October, and the minimum-in August and September, with an annual dynamics with an amplitude of 20%.
