Research of interrelation of life expectancy and mental health: population and regional approach
Introduction. Now it is impossible to call a medico-demographic situation in Russia safe, despite the outlined positive tendencies. Our country still lags behind the developed countries of the world on the level of average life expectancy (takes the 110th place), but advances on incidence and mortality, especially from the preventable reasons. Research objective. An objective of this research is the assessment of correlation of life expectancy and mental health at the population and regional level by means of methods of mathematical statistics. Material and methods. As information base data of Rosstat «Regions of Russia» and «Health care in Russia» were used. Indicators on 80 subjects of the Russian Federation (without autonomous areas) for the ten-year period (2005-2014) have been created in the form of the database consisting of the following blocks: medico-demographic situation, level of economic development of the territory and wellbeing of the population, development of social infrastructure, ecological and climatic conditions, scientific researches and innovations. In total about 70 indicators characterizing various aspects of regional development. When carrying out calculations panel data (Panel Data) for 80 regions of Russia in 10 years which combine both indicators of spatial type (cross-section data), and information on temporary ranks (time-series data) were used. Three models of regression according to panel data have been realized: the integrated model of regression (pooled model), regression model with the fixed effects (fixed effect model), regression model with random effects (random effect model). Results. Application of methods of mathematical modeling for regions of Russia and the Republic of Karelia has allowed to establish that life expectancy is considerably connected with socio-economic factors (welfare, the monetary income of the population). An important role is played by the situation of social tension (a social stress) caused by transition to market economy. Conclusion. Results of calculations allowed to define the priority directions in the field of development of the mental health and psychotherapeutic services, especially at the regional level (on the example of the Republic of Karelia).
