It should be noted, that the state of health of the population and the development of society as a whole is largely determined by the level of adolescents health who have a significant impact on the health of the nation as a whole, and form the cultural, intellectual, industrial and reproductive potential [2, 3].This article analyzes the health status indicators of adolescent population of the Republic Sakha (Yakutia), including the dynamics of the disease, including socially conditioned diseases, disability and mortality among the teenage population.To study of health status of adolescents, social condition of life and there dynamic we use statistic materials of Yakut Republican Medical informative-analytic center, carry out medical prophylactic examination and survey research of 748 adolescents in 7 districts of republic, using questionnaires Global epidemic surveillance system health status of schoolchildren with support from WHO / UNAIDS / UNICEF / UNESCOCO.Established negative trend of deceasing of adolescent population, the increase in performance of both primary and general morbidity. Out of the total incidence of first place ranking among teenagers occupied by respiratory diseases, diseases of the eye and diseases of the digestive system. The most intensive increased prevalence of neurological diseases, cardiovascular system diseases, injuries and poisoning, and others external causes. Over the years remain unstable indicators of socio-caused diseases (alcoholism, drug addiction, tuberculosis, sexually transmitted infections). Despite the positive dynamics of some socially constructed and socially significant diseases, the relevance of this problem persists. Analysis of the dynamics of disability among children and adolescents showed a reduction in performance. In the structure of disability dominate diseases of the nervous system and sensory organs, congenital malformations and mental illness.
