[RANK INDICES METHOD AND ITS USE FOR THE COMPARATIVE ANALYSIS OF POPULATION HEALTH].

There is presented a calculation method aimed to elevate the informative value of the integral indices of the social and hygienic monitoringfor purposes of comparative analysis. The method of rank indices is based on the ranking of monitoring objects on the values of primary indices on the base of which there are calculated the integral such indices as, for example, life expectancy. There are presented results of the use of this method for the comparative analysis of mortality rate in WHO Member States for the period of 1990-2011. There were revealed specialfeatures of mortality trends which cannot be detected when using only mortality rates or the life expectancy. In particular, for Russia there was shown that, in spite of the downward trend in child and adolescent mortality rate observed in the last decade, the country's world rankings for these indices fail to achieve the level of 1990. This means that the competitiveness of the country, sharply declined in the 90's, was not restored until now. There are described some features of the use of the method of rank indices for the analysis of indices of the environment state, public health and its socio-economic determinants.

Aging is a simple deprivation syndrome driven by a quasi-programmed preventable and reversible drift of control system set points due to inappropriate organism-environment interaction.

There are two well-known but opposing concepts of the reason for aging. The first supposes that senescence is programmed similarly to the genetic program of development from a zygote up to a mature organism. Genetically determined senile wasting is thought to be associated with the necessity to renovate the population to ensure its adaptation and survival. According to the concept of the stochastic aging (due to accumulation of occasional error and damage), there is no built-in program of aging. There is only a program of development up to the state of maturity, and then the organism should be able to maintain itself limitlessly. However, although the efficiency of repair systems is assumed to be rather high, it is less than 100%. Just this has to result in aging because of accumulation of various errors. We have continued and developed another approach that considers both programmed and stochastic concepts to be incorrect. Aging is a simple deprivation syndrome driven by preventable and even reversible drifts of control systems set points because of an inappropriate "organism-environment" interaction.
