Ранняя диагностика психоэмоционального состояния и своевременная коррекция могут снизить риск формирования отклонений в психическом здоровье детей и подростков.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. У учащихся начального (n = 247), среднего (n = 297) и старшего звена обучения (n = 146) общеобразовательных организаций проведена донозологическая диагностика и коррекция стресса с помощью современных аппаратно-программных комплексов.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что с увеличением уровня нервно-психического напряжения в 1,3 раза у учащихся от начального к старшему звену регистрировалось повышение тревожности в 1,2 раза в повседневной и учебной сферах, враждебности в 1,3 раза и агрессивности в 1,2 раза. Удельный вес учащихся с высоким уровнем непродуктивного нервно-психического напряжения увеличился в 1,4 раза, учащихся с состоянием избыточного сковывающего напряжения – в 3,5 раза на фоне снижения периферической температуры тела в 1,2 раза, увеличения частоты пульса в 1,2 раза и мышечного напряжения в 1,3 раза. Показано, что использование технологии функционального биоуправления методом диафрагмального дыхания снижало тревожность на 15,9% в повседневной жизни, на 24,1% в академической сфере и негативных эмоциональных переживаний в учебной деятельности на 21,5%, способствовало нормализации физиологических маркёров стресса, формированию оптимального вегетативного баланса для реализации всех возможностей при стрессовой ситуации и состояния психофизиологического благополучия у каждого второго учащегося.</p></sec><sec><title>Ограничения исследования</title><p>Ограничения исследования. Использование диафрагмального дыхания в качестве метода коррекции психоэмоционального состояния может ограничивать возможность экстраполяции полученных данных на другие исследования, в которых использовались электромиографические, электроэнцефалографические, температурные тренинги или их комбинации.</p></sec><sec><title>Заключение</title><p>Заключение. Доказана эффективность применения методов донозологической диагностики и коррекции стресса как экологического фактора среды обитания, что позволяет рекомендовать их для внедрения и использования в общеобразовательных организациях.</p><p>Соблюдение этических стандартов. Исследование выполнено в соответствии с Хельсинкской декларацией Всемирной медицинской ассоциации (последняя редакция), одобрено локальным этическим комитетом ФГБОУ ВО ОрГМУ Минздрава России (протокол № 258 от 09.10.2020 г.). Все участники и их законные представители дали информированное добровольное письменное согласие на участие в исследовании.</p></sec><sec><title>Участие авторов</title><p>Участие авторов: Сетко Н.П., Сетко А.Г. – концепция и дизайн исследования, редактирование; Жданова О.М., Лукьянов С.Э. – сбор и обработка материала, статистический анализ, написание текста.

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.</p></sec><sec><title>Materials and methods</title><p>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.</p></sec><sec><title>Results</title><p>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.</p></sec><sec><title>Limitations</title><p>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.</p></sec><sec><title>Conclusion</title><p>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.</p><p>Compliance with ethical standards. The study complies with the latest revision of the Helsinki Declaration; approved by the local ethics committee of the Orenburg State Medical University (protocol No. 258 dated 10/09/2020).
