New perspective on geographical mortality divide in Russia: a district-level cross-sectional analysis, 2008-2012

Health disparities in Russia at the regional and global scales

BACKGROUND

The capacity for health comparisons, including the accurate comparison of indicators, is necessary for a comprehensive evaluation of well-being in places where people live. An important issue is the assessment of within-country heterogeneity for geographically extensive countries. The aim of this study was to assess the spatial and temporal changes in health status in Russia and to compare these regional changes with global trends.

METHODS

The index, which considers the infant mortality rate and the male and female life expectancy at birth, was used for this purpose. Homogeneous territorial groups were identified using principal component analysis and multivariate ranking procedures. Trend analysis of individual indicators included in the index was also performed to assess the changes over the past 20 years (1990-2017).

RESULTS

The study indicated a trend towards convergence in health indicators worldwide, which is largely due to changes in infant mortality. It also revealed that the trend of increasing life expectancy in many regions of Russia is not statistically significant. Significant interregional heterogeneity of health status in Russia was identified according to the application of typological ranking. The regions were characterized by similar index values until the mid-1990s.

CONCLUSIONS

The strong spatial inequality in health of population was found in Russia. While many regions of Russia were comparable to the countries in the high-income group in terms of GDP, the progress in health was less pronounced. Perhaps this can be explained by intraregional inequality, expressed by significant fluctuations in income levels.

Spatial patterns of male alcohol-related mortality in Belarus, Lithuania, Poland and Russia

INTRODUCTION AND AIMS

Eastern Europe is known to suffer from a large burden of alcohol-related mortality. However, persisting unfavourable conditions at the national level mask variation at the sub-national level. We aim to explore spatial patterns of cause-specific mortality across four post-communist countries: Belarus, Lithuania, Poland and Russia (European part).

DESIGN AND METHODS

We use official mortality data routinely collected over 1179 districts and cities. The analysis refers to males aged 20-64 years and covers the period 2006-2014. Mortality variation is mainly assessed by means of the standardised mortality ratio. Getis-Ord Gi* statistic is employed to detect hot and cold spots of alcohol-related mortality.

RESULTS

Alcohol-related mortality exhibits a gradient from very high levels in northwestern Russia to low levels in southern Poland. Spatial transitions from higher to lower mortality are not explicitly demarcated by national boundaries. Within these countries, hot spots of alcohol-related mortality dominate the territories of northwestern and western Russia, eastern and northwestern Belarus, southeastern Lithuania, and eastern and central Poland.

DISCUSSION AND CONCLUSIONS

The observed mortality gradient is likely associated with the spread of alcohol epidemics from the European part of Russia to the other countries, which appears to have started more than a century ago. Contemporary socioeconomic and demographic factors should be taken into account when developing anti-alcohol policies. The same is true for the peculiarities of culture, norms, traditions and behavioural patterns observed in specific geographical areas of the four countries. Reducing alcohol-related harm in the areas identified as hot spots should be prioritised.
