Background. Hygienic education and the creation of conditions for motivating schoolchildren to health-saving behavior is the most important task of parents, teachers, the public, preventive medicine and the state. Aim. Studying the advantages and disadvantages of educational technologies used in working with schoolchildren and their parents when conducting hygiene education in educational institutions. Material and methods. The study consisted of four stages. At the first stage, a selective audit of information posted on 24 official websites of educational organizations in Kazan was carried out. At the second stage, 142 parents were surveyed. The third stage included work with 25 teachers in focus groups. At the fourth stage, a survey of 374 (192 girls and 182 boys) students in grades 710 was conducted. The results were processed using the methods of parametric and nonparametric statistics (mean value, error of the arithmetic mean, proportion of the feature, Kendal coefficient, 2 at a significance level of 0.05). Results. Most (22 out of 24 analyzed) websites of educational organizations did not contain information on student health protection. The survey results of 142 parents showed low interest in the work carried out at the school. Evaluation of leaflets on healthy eating allowed us to choose the two most useful and informative ones: For a teenager about nutrition. Food for the mind (Xav=9.14 points) with consensus (W=0.744; =0.0456) and Healthy food for schoolchildren (Xav=9.03 points; W=0.757; =0.0398). The study of educational technologies used by teachers to instill in students the basic principles of health saving showed that teachers do not always use active forms. The result of a survey of 374 students was the identified need to improve knowledge in matters of self-regulation of the psychological state. Conclusion. The study of the advantages and disadvantages of educational technologies used in the conduct of hygienic education and training of schoolchildren and their parents in the conditions of educational organizations requires further improvement and wider use of active forms of education that meet the needs of students.

Introduction: Training in the cadet corps involves an increase in motor activity, which affects the level of functional capabilities of adaptation systems. The objective of our work was to study the features of functional reserves of the cardiorespiratory system in cadets. Materials and methods: The observation group consisted of 74 cadets aged 10–13 years; the comparison group consisted of 26 secondary school boys. The study of the mode of physical activity was carried out using a questionnaire. Evaluation of fitness and physical performance was carried out according to bioimpedance analysis of body composition and dynamometry. The functional state of the cardiorespiratory system was assessed by the parameters of the breath holding test during inhalation and exhalation, the Skibinskaya index, spirography, cardiointervalography with an active clinoorthostatic test. Statistical analysis was performed using standard methods. Results: Every second cadet regularly goes in for physical education and sports. The physical development of cadets is characterized by higher values of the phase angle, active cellular and musculoskeletal mass, and dynamometry. The functional reserves of the cardiorespiratory system according to the Skibinskaya index, the values of the breath holding time during inhalation and exhalation in cadets were 1.3–1.7 times higher than those in secondary school boys; the number of children with good test results in the observation group was 1.4-3.3 times more than that in the controls. The indices of cardiointervalography (variation range, vegetative balance index, vegetative balance index, and tension index) in cadets differed significantly from those in the comparison group (by 1.2–1.6 times) and indicated the activation of the parasympathetic part of the autonomic nervous system at rest and the activity of the sympathetic part under load in response to a stress factor. Every third child in the observation group had an initial vagotonia; hypersympathicotonia was found in isolated cases. A hypersympathicotonic variant of autonomic reactivity was registered in 60.8 % of cadets during the exercise test. Conclusion: Sufficient physical activity of cadets improves the indices of physical development and muscle strength, which is accompanied by an increase in the functional reserves of the respiratory and cardiovascular systems. However, the presence of hypersympathicotonic autonomic reactivity may indicate tension of adaptation processes during exercise.
Introduction. Growing prevalence of allergic rhinitis (AR) and significant socioeconomic losses related to implementing medical and prevention activities indicate the necessity to examine what role exogenous factors play in the disease onset and development. The aim of this study was to establish pathogenetic peculiarities of AR onset and development in schoolchildren under combined exposure to various environmental risk factors. Materials and methods. We analyzed results of clinical and laboratory examinations of schoolchildren’s health and data obtained by questioning and taken from diaries of daily rations provided at school for four hundred thirty nine AR children. They attended either an ordinary secondary school or a school with profound studies of some subjects. Influence of risk factors on clinical and laboratory indicators was evaluated by using one-factor logistic regression models that described “adverse exposure – likelihood of a response (effect)” relationships. Leading risk factors and pathogenetic peculiarities of AR onset and development were identified based on analyzing established cause-effect relations “risk factor – laboratory indicator – likelihood of diagnosing AR». Results. More significant violations of hygienic standards were established in schools with profound studies of some subjects; we identified improper management of educational activities, non-rational diets, and too intensive use of electronic devices. Likelihood of AR is 4.2 times higher for schoolchildren in such schools than for their counterparts from ordinary schools (OR=4.2) under combined exposure to adverse factors related to the educational process, diets, the environment (blood contamination with nickel, chromium, manganese, zinc, benzene, and toluene) and low physical activity. We established cause-effect relations between the disease development and the examined factors as well as their contributions to likelihood of risk-associated AR (12–60 %). We identified adverse laboratory effects in AR children who attended schools with profound studies of some subjects and established their association with affecting environmental factors. Pathogenetic peculiarities of the disease onset and development were posited based on modelling associations between laboratory indicators of disrupted homeostasis and AR development. Limitations. The examination was performed with 439 schoolchildren participating in it. Participants were not divided into sex-specific groups when describing peculiarities of allergic rhinitis development. Conclusion. The established key pathogenetic components in development of risk-associated AR are relevant targets for hygienic activities as regards the educational process and quality of the environment
