Last decades the phenomenon of ageing population at the expense of reduction of birth rate and continuous growth of life expectancy is observed and moreover the life expectancy increase has almost linear character. In our opinion, this growth will stop the next years and there will be a considerable reduction of life expectancy. Roughly it should occur after 2010 year when the persons born in second half of the XXth century, i.e. after 1950 year, will start to enter advanced age. The reason of this drama consist in our opinion in catastrophic deterioration of primary health at persons born in second half of XXth century owing to action of "stop-evolution" factors and inhabitancy crisis. "Primary health" as definition in this text means combination of congenital predisposition to diseases (pathogenicity) with congenital possibility to autorecovery (sanogenicity). So the quality of primary health depends on features of the person genome and features of the person antenatal period of life including the delivery. Among factors of "stop-evolution" breaking natural selection consequently of sharp decrease in number of birth and fertility in population and as consequence worsening quality of congenital sanogenicity we consider first of all social factors. Among factors operating due to crisis of an inhabitancy and as consequence increase of congenital pathogenicity we consider anthropogenic factors (success of medicine, changes of food, technogenic factors). The analysis of own data of diabetic patients born during various periods of the XXth century (before 1908, in 1909-1923, 1924-1938, 1939-1953 yrs) has demonstrated the essential reduction of number of long-livers in a family (30,7; 35,0; 25,4; 27,8% accordingly), and on the other hand the sharp increase in frequency of cases of a family diabetes during the century (20,0; 5,9; 36,8; 64,7% accordingly). Thus, the action of some factors described by us has been already shown in first half of XXth century. To overcome the given "gerontology crisis" apparently, the interdisciplinary approach including joint researches with the subsequent development of recommendations, with participation not only gerontologists/geriatrists, but also pediatrists, andrologists/gynecologists, endocrinologists, genetics, ecologists and sociologists is necessary.
