The state of health in children and adolescents during the time of education in secondary schools is getting worse: the prevalence rate of functional disorders and chronic diseases is increasing. There was executed the assessment of the overwroughtness of the training-education process in secondary school institutions. The prior characteristics of the educational activity are: intellectual, sensory, emotional loads; their monotony and mode of educational activity, school work intensity. The system of indices of the overwroughtness of the education labour was formed with account ofpsycho-physiological characteristics of children's organism. There was performed the research of the overwroughtness of educational activity in 820 schoolchildren. The overwroughtness of the educational process was evaluated on the basis of chronometry research, questionnaire survey of teachers and parents, and with taking into account the organization of educational process. In questionnaire survey there were involved 52 teachers and 389 parents. The assessment of overwroughtness factors of the educational activity was carried out in 5-10th classes for academic disciplines: Russian Language, Literature, Mathematics, History, Geography, Foreign Languages. It was found that the characteristics of "mental load" in schoolchildren are established to be the one of the main limiting factors that allow to refer training activities to "overwroughted of first degree" (3.1 class). Sensory loads on the studied academic subjects are rated as the second class of overwroughtness and are "permissible." The monotony of loads was revealed to correspond to 1st and 2nd class of overwroughtness and is therefore an optimal or acceptable. Training activities in the traditional educational institution corresponds to the 2nd class of overwroughtness - "permissible." The arduousness of the educational process in an innovative school is rated as the third class of the first degree ofthe overwroughtness (3.1). According to results of the study of the arduousness of the educational labor the study of mathematics in grades 5-9 on indices of the mental load was noted to correspond to the 1st degree of arduous activity (3.1 class). The acceptable level of the arduousness of the training and educational labour in nearly all classes was established in the Russian language, Literature, History and Geography, Foreign language. High school students are established to be exposed to effects of emotional load more than mid-level students. There are developed proposals on the optimization of the learning process, allowing to reduce the level of intellectual, sensory, emotional load.
Introduction. Changes in the education system have an impact on the health of schoolchildren. Purpose. To study the dependence of the adaptive capacity of schoolchildren studying in schools of various types on the intensity of educational work. Material and methods. The adaptive abilities of the organism of children (aged 7-17 years) were studied in conditions of different intensity of the educational process. There were surveyed 472 cases from traditional schools, 482 people - from specialized schools. We evaluated the statistical significance of the differences in quantitative (Student t-test) and qualitative traits (χ2). The relationship was studied using the Spearman correlation coefficient. Results. The intensity of educational work accounted for 3.6-3.8 points in 52 ± 2.4% of students in specialized type; 1.6-3.5 - in traditional schools. Intellectual loading is the most sensitive index when training in programs with a specialized study of subjects. The adaptive potential of students of specialized schools in a state of functional stress in the lower grades is found by 1.8 times (p < 0.002), on average - 2.2 times (p < 0.001), more often than in traditional schools. However, the proportion of children with functional stress in the upper grades does not differ (22-27%). A high direct correlation was found between the values of the adaptive potential and intellectual loads. Conclusion. Criteria for learning loads requiring a review of their volume in the curriculum of specialized schools are identified. The negative impact of school loads on the adaptive capabilities of a growing organism has been proven.
Introduction. Prevention of the syndrome of autonomic dysfunction (SAD) remains relevant due to the high prevalence and risk of transformation into chronic diseases of the cardiovascular system. Aim to assess the information content of the environmental factors and lifestyle in the formation of SAD in school children. Material and methods. The studies were carried out in urban and rural iodine-deficient territories of the Irkutsk region with different levels of the technogenic load. A total of 786 school children were examined, 250 children aged 7-17 years were included in the group for the analysis of informative factors. Factors of a way of life, quality of an inhabitancy, biological factors are studied. The influence of the factors studied on the formation of SAD was determined using the Bayes method. Results. SAD was found in the surveyed group at a frequency of 28.2 ± 2.8 per 100 children. The highest prevalence of this pathology was noted in children in the industrial city - 69.2 ± 3.7, in rural areas - 7.7 ± 2.8. Priority risk factors that can contribute to the development of a SAD in children are identified: an index of the air pollution = total exposure of formaldehyde > volume of training load > intensity of training work > child gender > excretion of formaldehyde > excretion of iodine in the urine> personal anxiety. Conclusions. The factors of the information content of risk factors in the formation of SAD in schoolchildren can be used for the early detection of persons at risk in conducting preventive medical examinations.
Irkutsk region is among territories of intense industrial development. Considerable part of the regional population is long exposed to chemical pollutants of environmental objects. Th e authors evaluated carcinogenic risk for the population of industrial centers and rural area. Findings are that maximal carcinogenic risk is carried by the urban population. Aggregated carcinogenic risk parameters evaluation proved inhalation to be a priority route of exposure. Irkutsk region appeared to have territories with high carcinogenic risk for public health. Among a list of chemicals in the ambient air are priority carcinogens: six-valent chromium and lead. The evidences necessitate measures on the risks minimization. Due to absent data on carcinogens content of drinkable water in some rural area, the necessity is to evaluate risk for the rural population by studies of drinkable water quality that does not match hygienic regulations, because oral one is a main route of carcinogens intake.
