Modern approaches to pre-nosological diagnostics and correction of environmental conditioned stress in children and adolescents

Introduction. Early diagnostics of the psycho-emotional state and timely correction of the identified deviations can reduce the risk of mental health deviations in the future in children and adolescents.Materials and methods. Pre-clinical diagnostics and stress correction were performed using modern hardware and software systems in students of three age groups: primary (n=247), middle (n=297) and senior (n=146) of general education institutions.Results. It was found that with an increase in the level of neuropsychic stress by 1.3 times, students from primary to senior levels showed an increase in anxiety by 1.2 times in everyday and academic spheres, hostility by 1.3 times and aggressiveness by 1.2 times, an increase in the proportion of students with a high level of unproductive neuropsychic stress by 1.4 times and with a state of excessive constricting tension by 3.5 times, against the background of a decrease in peripheral body temperature by 1.2 times, an increase in muscle tension by 1.3 times and a pulse by 1.2 times. The use of functional biofeedback technology using the diaphragmatic breathing method was found to contribute to a decline in anxiety by 15.9% in everyday life, by 24.1% in the academic sphere and negative emotional experiences in educational activities by 21.5%, normalization of physiological markers of stress, formation of an optimal vegetative balance for the implementation of all possibilities in a stressful situation and a state of psychophysiological well-being in every second student after mastering the skill of diaphragmatic breathing.Limitations. The use of diaphragmatic-relaxation breathing as a method for correcting the psychoemotional state may limit the possibility of extrapolating the obtained data to other studies that used electromyographic, electroencephalographic, temperature training or their combinations.Conclusion. The effectiveness of the use of pre-clinical diagnostics and stress correction methods as an environmental factor of the habitat has been proven, which allows recommending them for implementation and use on the basis of general education institutions.Compliance with ethical standards.
