Results of assessment of actual nutrition of medical university students and its’ impact produced on their alimentary status are presented in this article. Rationality and adequacy of nutrition of medical students were assessed. Amount and kinetics of macro- and micronutrients at medical students were investigated. As result, these parameters are shown to be informative prognostic criteria of early changes in organism. Also they can be used for identification of gender differences in students’ alimentary status.

We conducted a study on the intensity of educational activities and determined the typology of the physiological reactions of the body of each of students with different levels of efficiency. The intensity of the educational process of students is given by the method of V.R. Kuchma, E.A. Tkachuk, N.V. Efimova, I.V. Mylnikova (2015) with a scoring of intellectual, sensory, emotional loads, mode and monotony of educational work. A survey of 295 students divided into three groups of 60 people was conducted at a time. There were students with a normal level of efficiency, with reduced efficiency and with significantly reduced efficiency. The functional state of the central nervous system, the autonomic nervous system was determined on the hardware-software complexes based on the methods of, respectively, variational chronoreflexometry and pulsometry. The leading factors of students’ educational activities were high intellectual, visual loads and irregular schedule of academic work, which were assigned to class 3 of 2nd degree on unsocial conditions. In conditions of intense learning activities, only every third student had a normal level of efficiency. We have established the fact of a decrease in the functional state of the central nervous system, stability of the nervous response, adaptive capacity due to the intra-system mismatch of the autonomic nervous system departments and its regulation levels in students with reduced and significantly reduced efficiency as compared with students with normal efficiency. Those can become a scientific basis for the formation of targeted preventive measures to improve the level of efficiency through the normalization of these physiological processes.

Results of the research of social and psychological adaptation of students of educational institution with the round-the-clock stay of Orenburg are given in article. It is shown that under the influence of a complex of adverse factors of the intra-school environment the level of social and psychological adaptation of students decreases that is shown by increase in the course of training of number of children with disadaptation in communicative and educational spheres, and characterized by emotional trouble, high level of uneasiness in usual life and in educational activity.

Objectives to identify the specific features of central nervous and respiratory systems functioning in pupils of last grades in secondary school in conditions of high intensity of educational work. Material and methods. The study assessed the intensity of the educational process in a multidisciplinary lyceum for more able learners and a secondary school for general education in accordance with the Federal Recommendations "Hygienic assessment of the intensity of students' educational activities". In both educational institutions, the observation groups were formed from pupils of grades 9th and 10th. The first group consisted of 200 children from the lyceum specializing in education of gifted learners. The second group included 200 children from a traditional secondary education school. The functional state of central nervous system was evaluated by the method of variational chronoreflexometry. The state of respiratory system was assessed using the spirography method. Results. In conditions of pronounced tension of the educational process (class 3.1), in the pupils of a multidisciplinary lyceum the level of nervous reaction was stabilized, the ability of the central nervous system to form an intra - and intersystem adaptation was increased in comparison with the corresponding data of general secondary school pupils who were studying with the optimal educational workload(class 1). These results can testify the sufficient training status of nervous processes as a result of intense cognitive activity underlined by the harmonious development of systems that ensure functioning of the central nervous system in an operational mode. Conclusion. The study results can be useful for educational institutions specializing in teaching students with increased educational abilities. We suppose that the introduction of techniques for the development of operational indicators of central nervous system into the educational process might ensure high intellectual achievements.

Introduction: In solving the problem of preserving and strengthening health of gifted schoolchildren representing the country’s main intellectual potential, the main component is the observance of hygienic requirements for conditions and organization of learning activities in educational establishments for gifted children and adolescents. The purpose of the study was to conduct a prenosological assessment of the health status of gifted adolescents influenced by various educational process factors. Materials and methods: Using hardware and software systems, we assessed the level of physical development, functional status of the central nervous, respiratory, and cardiovascular systems in 300 gifted adolescents in grades 9–11 (15–17 years of age). Results: We established that under the conditions of a boarding school (lyceum), gifted schoolchildren were exposed to such health risk factors as increased study loads, their irrational distribution during the school day and week, and a high level of tension in the educational process (class 3.1). It was proved that the educational process factors affected the functioning of the basic systems of the body of gifted schoolchildren. High study loads of a pronounced degree of tension ensured an improvement of the functional status of the central nervous system of gifted school-age adolescents by stabilizing the nervous reaction, increasing the functional level of the nervous system and the ability of the central nervous system to form the body’s adaptive system when adapting to the factors of the educational process in the in the dynamics of learning. Maintaining a high level of functioning of the central nervous system in gifted school-age adolescents was ensured by the multiparameter interaction of the main body systems, which was characterized by an increase in the functional parameters of the respiratory system, a change in vegetative regulation, and a decrease in the level of biological adaptation. Conclusions: Our findings determine the need for systematic screening of gifted children in educational institutions to identify the level of their prenosological health in order to maintain and increase the adaptive potential of gifted adolescents.
