Correlation-regression analysis of medical demographic characteristics, parameters of the economic status of the country, and level of life in 1990-1994 showed a marked correlation between a drop of the level of life in Russia and deterioration of the medical demographic situation: decrease of birth rate, increase of mortality, and shortening of the expected life span. The most significant factors were decrease of the total gross product in % of 1990, decrease of the number of staff of industrial enterprises, and a lower consumption of meat and milk products in kg per capita. A single-factor exponential model proved to be the most adequate. The derived equations may be used for predicting the medical demographic parameters for Russia using the detected factors.
