RESUMO
The purpose of the study is to establish characteristics of quality of life of adolescents and substantiate it as a reference criterion of pre-nosologic condition of health for mass screening observations of adolescent population. During puberty, in adolescents, mainly in girls, deterioration of quality of life is established. At that, minimal indices of quality of life were registered in adolescents 12 years old, that is probably conditioned by decreasing of level of functioning of central and respiratory systems against the background of vegetative balance disorders in this age group as compared with students of other age groups. The dependence of scales of mental component of quality of life of adolescents is established from following functional indices of central nervous system: stability of nervous reaction (r = 0.4) and level of functional capabilities of formed functional system (r = 0.4-0.5); physical component of quality of life of students from functional level of nervous system (r = 0.4-0.5), from integral indices of autonomic nervous system (r = -0.4-0.5); from indices of functional state of respiratory system (r = 0.4-0.6). The obtained data allows to consider quality of life as a reference diagnostic tool for assessing pre-nosologic health condition in mass screening observations of adolescent population.
