Introduction. The management of the educational process for modern students is associated with the active and prolonged use of digital technologies and devices. If the studies of the past years have given a detailed and comprehensive assessment of hygienic risk factors in the traditional management of the educational process, now there is a need to clarify the hygienic safety of the management of the educational process in remote form and when using digital devices in teaching against the background of a high commitment of children and adolescents to use gadgets at leisure. Materials and methods. A comparative analysis of the intensity of the educational process in primary school students according to the federal recommendations of the Federal State Educational Institution “All-Russian Development Society for School and University Medicine and Health”-16-2015 (version 1.1) “Hygienic assessment of the intensity of students’ learning activities” in traditional and distance education forms according to the timing of seventy five lessons in mathematics and Russian language. Results. In the distance learning form, compared with the traditional one, the intensity of educational work was found to increase from 2.9±0.05 points (class 3.1) to 3.4±0.02 points (class 3.1), p≤0.05 due to intense 2 degrees of intellectual loads (3.6±0.01 points), sensory loads (3.6±0.03 points), monotony (3.7±0.03 points) and intensity of the 1st degree of the mode of educational activity (3.1±0.03 points). The increase in sensory loads was associated with the use of information and communication tools during training, such as a computer, laptop, tablet, smartphone. Up to 15.3% of students during the traditional period and 35.5% of students during the distance education period used smartphones prohibited for teaching. The majority of students in the distance study form used a computer in 75.6% of cases, every third student (35.4%) used a laptop, with the traditional form of education, the proportion of students who used computers and laptops in teaching was 12.3–15.6%. Limitations. The study on the assessment of the intensity of the educational process in various forms of education was limited by the fact that the sample was limited to primary school students, which does not allow extrapolating them to the total population of middle and senior level students. The timing of the intensity of educational activity in the lessons of mathematics and Russian language, which relate to difficult subjects, could determine a higher intensity of the educational process than if the assessment took into account all subjects. Conclusion. The obtained data especially emphasize the relevance of the adopted hygienic standards governing the total time of using information and communication tools both during the school day in the classroom and taking into account the entire time budget per day, and the need to control their use by students.

Introduction. Cardiopulmonary disorders should be considered as a complex process, in the pathogenesis of which excess body weight can play an important role. Without timely prevention, the processes of inflammation and hypoxia, characteristic of abdominal obesity, can accelerate the development of cardiopulmonary insufficiency. This is especially relevant for workers in metallurgical industries with harmful working conditions. Materials and methods. The study included one hundred thirteen long-term labour experience workers of the main occupations of aluminum production and 66 workers of the paramilitary mine rescue brigade. The average age of metallurgists was 47.81±0.43 years, mine rescuers – 46.91± 0.53 years, p=0.213. All the subjects underwent a study of the external respiration function and echocardiography according to standard methods. Results. In persons with abdominal obesity the average values of the vital lung capacity were significantly lower: 83.59±2.19% vs. 91.16±1.31% (p=0.0021) among metallurgists and 86.43±2.67% vs. 94.63±1.43% (p=0.0041) among the workers of the paramilitary mine rescue brigade, a similar pattern was revealed in terms of the forced exhalation volume for the first second – 77.1±2.41 vs. 88.24±1.38% (p=0.00003) and 85.6±3.13% vs. 93.34±1.31% (p=0.0094), respectively. The studied average values of the indices of diastolic function of the right ventricle were typical for the development of its dysfunction in metallurgists, and also indicated the absence of the influence of abdominal obesity on them in all examined subjects. Limitations. The study was limited by the number of the examined persons undergoing periodic medical examination at the Research Institute for Complex Problems of Hygiene and Occupational Diseases. Conclusion. Lower respiratory indices were recorded in persons with abdominal obesity, while obstructive ventilation disorders were detected only in aluminum production workers. Abdominal obesity was not associated with the indices of diastolic function of the right ventricle. The tendency to the formation of diastolic dysfunction of the right ventricle had been noted in the workers of the main occupations of aluminum production.

Introduction. The results of the study of the nature of the formation of the thermal state in workers under the influence of extreme levels of the heating microclimate with multifactorial exposure against the background of heavy physical labour, justify the need to develop and experimentally evaluate a set of preventive measures. Such measures need to prevent chronic overheating, with the mandatory use by workers of modern effective personal protective equipment from infrared radiation. The purpose of the study – the study of the effectiveness of personal protective equipment made of metallized materials in real production conditions, for the prevention of chronic overheating from exposure to extreme levels of infrared radiation with multifactorial exposure against the background of heavy physical labour. Materials and methods. To assess the possibility of using personal protective equipment in the conditions of modern forging and pressing production, there were taken protective clothing sets made of the material OXA-440, consisting of a cotton-asbestos lining and a metallized material with an aluminum surface. In the manufacture of prototypes of workwear, the topography and the estimated area of the irradiated area of the body surface, and the moisture and air tightness of metallized materials, were taken into account. The effectiveness of personal protective equipment was evaluated with taking into account the indicators of the thermal state of the workers of the main occupations who used two sets of the specified protective clothing alternately. The thermal state of the body was studied in accordance with the guidelines of the MUK 4.3.1895-04 and the provisions of the standard GOST R ISO 9886-2008. Studies on the hygienic assessment of workwear were carried out in the cold and warm periods of the year. A questionnaire survey was conducted to subjectively assess the usability, design and protective properties of workwear made of metallized material. Results. The main sources of thermal radiation in the studied production are incandescent to a temperature of over 1200°C with metal forgings of various lengths and various profile configurations, which largely determine the variability in the degree of radiation intensity of the radiant energy flow at the workplaces of blacksmiths and heaters. The formed thermal state of the workers of the specified occupational groups, dressed in standard cotton workwear, during the performance of the main work operations during the first half of the working shift in the cold and warm periods of the year, is estimated as the maximum permissible, requiring a limit of working time – no more than one hour per working shift. The use of workwear made of metallized materials in the cold period of the year led to a slight improvement in the thermal condition, which allowed to prolong the time spent at the workplace to 2 hours. When using the original design of a protective suit made of a metallized material characteri
介绍在繁重体力劳动的背景下，在极端水平的加热小气候和多因素暴露的影响下，工人热状态形成的性质的研究结果证明了制定和实验评估一套预防措施的必要性。这些措施需要防止长期过热，工人必须使用现代有效的个人防护设备，以防红外辐射。本研究的目的是研究由金属化材料制成的个人防护设备在实际生产条件下的有效性，以防止在繁重体力劳动的背景下，因暴露于极端水平的红外辐射和多因素暴露而导致的慢性过热。材料和方法。为了评估在现代锻造和冲压生产条件下使用个人防护设备的可能性，采用了由OXA-440材料制成的防护服套装，由棉石棉衬里和铝表面金属化材料组成。在工作服原型的制造过程中，考虑了身体表面照射区域的地形和估计面积，以及金属化材料的湿度和气密性。在评估个人防护装备的有效性时，考虑了交替使用两套指定防护服的主要职业工人的热状态指标。根据MUK 4.3.1895-04的指南和GOST R ISO 9886-2008标准的规定，对身体的热状态进行了研究。在一年中的寒冷和温暖时期对工作服的卫生评价进行了研究。对金属化材料工作服的可用性、设计和防护性能进行了问卷调查。后果在所研究的生产中，热辐射的主要来源是温度超过1200°C的白炽灯，具有不同长度和不同轮廓配置的金属锻件，这在很大程度上决定了铁匠和加热器工作场所辐射能流辐射强度的可变性。在一年中的寒冷和温暖时期，穿着标准棉质工作服的特定职业类别的工人在上半个工作班次执行主要工作操作期间形成的热状态被估计为最大允许状态，需要限制工作时间——每个工作班次不超过一小时。在一年中的寒冷时期，使用金属化材料制成的工作服使热条件略有改善，这使工作时间延长到2小时。当使用由金属化材料制成的防护服的原始设计时，该防护服具有防潮和气密性能，并在一年中的温暖时期覆盖身体表面的大面积区域，工人的热状况没有改善。通过问卷调查，测试材料具有良好的反射性能和力学性能。工人们在改进工作服设计方面表达的愿望和建议建议建议，考虑到这些意见，开发由这种金属化材料制成的特殊防护服的新设计样品。局限性所选择的研究方法决定了其在特定生产中使用的可能性的限制，其特点是生产环境的多因素性质，背景是繁重的体力劳动和由技术过程的具体情况决定的极端红外辐射水平。所获得的研究结果客观化了进一步研究的主题——金属化材料制成的特殊防护服新设计样品的开发和有效性评估。结论所进行的研究结果表明，新型金属化材料具有良好的反射和机械性能。在问卷调查中，工人们表达了他们对改进工作服套装设计的愿望和建议，在创建新的特殊防护服设计样本时必须考虑到这一点，以便在暴露于极端工业红外辐射的条件下工作时将其作为主要防护手段。

Introduction. Emotional burnout is a condition common among workers in “helping” occupations. The syndrome of emotional burnout among workers of the main occupations of the coal industry has not been studied enough, especially in terms of its relationship with such indicators of mental health as personal, situational anxiety and alexithymia. The relationship between emotional burnout syndrome and risk factors for the development of cardiovascular diseases has not been sufficiently studied. The purpose of the study to investigate the relationship of emotional burnout syndrome with the level of personal, situational anxiety and alexithymia, and the frequency of risk factors for the development of cardiovascular diseases, such as smoking, overweight, arterial hypertension and low physical activity in coal industry workers with occupational diseases. Materials and methods. Two hundred seventy-two coal miners with occupational diseases (dust lung pathology, diseases of the musculoskeletal system, vibration disease) were examined using questionnaires by V.V. Boyko, Spielberger-Khanin, and Toronto Alexithymia Scale. According to the survey, the frequency of smoking and low physical activity was determined, the frequency of arterial hypertension and overweight was identified by the results of a clinical examination. Results. The prevalence of emotional burnout syndrome was 27.9%. A higher frequency of personal anxiety (61.1%), situational anxiety (57.1%) and alexithymia (94.7%) was revealed in emotional burnout syndrome. The frequency of smoking, arterial hypertension tended to increase with emotional burnout, the frequency of overweight, and low physical activity did not differ. Limitations. The study was limited to a sample of 272 coal miners with occupational diseases, examined using questionnaires by V.V. Boyko, Spielberger-Khanin, and Toronto Alexithymia Scale. Conclusions. Emotional burnout syndrome is associated with the development of personal and situational anxiety, alexithymia and may be a risk factor for the development of cardiovascular diseases.

Introduction. Polyneuropathies are widespread among the population. Diabetes mellitus and industrial vibration are common causes of polyneuropathy, having common links of pathogenesis involving the autonomic nervous system. The therapeutic effects of ischemic preconditioning are realized by influencing pathogenetic mechanisms, and therefore their study in polyneuropathies of various genesis is of scientific interest.
The aim of the study was to investigate the remote clinical effects of ischemic preconditioning in polyneuropathies of various genesis.
Materials and methods. Twenty-five patients divided into 2 groups with lower extremity polyneuropathy of vibration and diabetic genesis were examined.
A clinical and electroneuromyographic study of the peripheral nerves of the lower extremities was performed. An analysis of heart rate variability before and after the treatment with ischemic preconditioning of the upper extremities was executed.
Results. In both groups of the patients with polyneuropathy a decrease in clinical manifestations in the form of pain syndrome and sensitive disorders (numbness and paresthesia), an improvement in vibration sensitivity, an increase in impulse conduction velocity, mainly along the peripheral sensory nerve fibers were revealed. The analysis of heart rate variability after performing of ischemic preconditioning showed a gaining of the power of very low frequency oscillations, which indicated to an increase in the compensatory capabilities of autonomic regulation.
Limitations. The investigation was limited by studying the clinical and electrophysiological characteristics of the peripheral nervous system in 25 patients with diabetes mellitus type 2 and vibration disease caused by the exposure to local and whole-body vibration.
Conclusion. After the course of treatment of the pain syndrome, sensitive and autonomic disorders decrease with an increase in the compensatory possibilities of autonomic regulation, the functions of conducting along sensory nerves improve. Positive distant effects of ischemic preconditioning in the correction of manifestations of vibration and diabetic polyneuropathies indicate to a systemic effect on the mechanisms of autonomic regulation. The distance is manifested in the remoteness of the appearance of effects from the place of application of the technique.

The purpose of the study: to substantiate the algorithm for assessing the provision of favourable conditions for the professional activities of schoolteachers based on an analysis of the lifestyle, work intensity and work regime, the state of health and psychological well-being in teachers. Materials and methods. The object of the study were teachers, tools for assessing the health promoting activities of schools. Surveys of lifestyle, work management, psychological status in teachers, medical examinations were conducted; analysis of tools for assessing the health promoting activities of schools. Results. Teachers are mostly women aged 30 to 59 years, with an average teaching experience of 23 years, have favourable family and living conditions. The optimal intensity of the teacher’s activity was found in 3.3%, acceptable – in 76.7%, tense of the 1st degree (harmful) – in 20.0%. 74.1% of teachers had a high level of occupatonal stress. Most teachers care little for their health. The leading behavioural risk factors for teachers are irrational unbalanced nutrition, irrational management of work and rest, low physical activity. Limitations. The use of a complex of research methods was one of the strengths of the study, which made it possible to identify potential factors affecting the health of teachers and develop an algorithm for assessing the provision of favourable conditions for the professional activities of schoolteachers. The program of an in-depth examination with the determination of the state of health and psychological status included only primary school teachers in Moscow, so the results of the study may vary depending on the place of residence (region) and personal characteristics, but can be generalized in relation to persons with similar background characteristics and conditions Conclusion. Modern professional risk factors for the health of teachers are determined. For the first time, indicators and an algorithm for assessing the provision of favourable conditions for the professional activity of schoolteachers are proposed.

Introduction. Clinical studies have shown the development of a complex of non-specific changes in internal organs due to chronic fluoride intoxication. The accumulation of fluorine in the body initiates free radical oxidation, promotes the development of pathological processes in the heart against the background of an imbalance between pro- and antioxidants, and vascular endothelial dysfunction. Pathological activation of intima cells leads to unbalanced production of damaging factors, changes in the hemostasis system, and entails morphological and functional disorders of organs. Materials and methods. The experiments were carried out on one hundred twenty white male rats. A morphological study of the heart, blood vessels was performed out at 1, 3, 6, 9 and 12 weeks of chronic fluoride intoxication. Results. The 1st-3rd weeks of the experiment are characterized by the preservation of the morphological structure of the cardiac muscle against the background of the previously shown a compensatory activation of the components of the redox-signalling system, which provided a decrease in the intensity of free radical processes. With an increase in the duration of exposure to sodium fluoride (6–9 weeks) these mechanisms failure was noted, which was manifested by the development of degenerative changes in the myocardium, progressing up to the 12th week of the experiment. The described changes correlated with the development of endotheliosis, degenerative and fibroplastic processes, circulatory disorders in the vessels of the heart and other organs. Limitations. Histological findings are descriptive. Conclusion. The results obtained are of practical importance for the elaboration of effective methods for timely organ-protective prevention and correction of pathomorphological disorders, depending on the organ-specific features and duration of fluoride intoxication.

Introduction. The antioxidant defense system is involved in protecting the body from long-term exposure to harmful damaging factors. Polymorphisms in the genes of antioxidant defense enzymes change the response to oxidative stress in occupational respiratory diseases such as asbestosis, silicosis, occupational asthma, and others. The aim was to study the polymorphism of the MnSOD (rs4880) and GPX1 (rs1050450) genes to predict the risk of developing chronic dust bronchitis in miners of the main occupations of coal enterprises in the South of Kuzbass. Materials and methods. One hundred eighty two coal mine workers with long-term exposure to high concentrations of coal-rock dust (exceeding the maximum permissible concentrations by up to 35 times), including 116 people with a previously proven diagnosis of chronic dust bronchitis, were examined. The comparison group (66 workers) consisted of the persons without a proven diagnosis, working in the same sanitary and hygienic conditions. Genomic DNA was isolated from peripheral blood leukocytes using phenol-chloroform extraction method. Typing of the MnSOD (rs4880) and GPX1 (rs1050450) genes was performed using the Real-Time method. Results. The chance of detecting the AA genotype of the MnSOD gene and the GG genotype of the GPX1 gene in long-term labour experience miners with chronic dust bronchitis was found to be 2 times and 6 times higher than in the comparison group, respectively. The AA GPX1 genotype had been shown to be a factor in resistance to the development of this disease. The combination of AA/GG genotypes of the MnSOD/GPX1 genes was statistically significantly associated with a 1.5-fold risk of developing chronic dust bronchitis. Combinations of genotypes of the MnSOD/GPX1 GG/AA, AA/AA, and AG/AA genes were associated with the resistance to the development of chronic dust bronchitis. The data obtained can be used for personalized prediction of the risk of developing chronic dust bronchitis in long-term labour experience miners of the main occupations. Limitations. The study was limited to the number of miners who underwent periodic medical examinations and were hospitalized at the Research Institute for Complex Problems of Hygiene and Occupational Diseases. Conclusion. The results obtained indicate to the contribution of the polymorphism of the MnSOD (rs4880) and GPX1 (rs1050450) genes to the development of chronic dust bronchitis.

Introduction. To a large extent, the personal state of health is determined by the lifestyle. A healthy lifestyle and preventive activity in workers are important factors in reducing risks for developing chronic non-communicable diseases. Ensuring a healthy, active life dictates the need for widespread implementation of self-assessment methods in the working population. Materials and methods. A sociological survey of one hundred twenty three oil-extraction workers in Western Siberia was conducted. The socio-hygienic study included an assessment of working conditions, damage to health caused by work environment factors, attitude to the environmental situation, and measures aimed at workers’ health promotion. Results. When analyzing the survey of oil-extraction workers, 94.2% of respondents have been shown to appreciate family relationships. One of the important factors of family well-being is the availability of home ownership (84.9%). Analysis of the results obtained shows the majority oil workers to satisfy with their working conditions (89.9%) despite a significant number of respondents were aware of the presence of hazardous occupational factors at their workplace: exposure to harmful chemicals (32.7%), the impact of unfavourable microclimate conditions (31.5%), fire and explosion hazards (31.0%), the impact of industrial noise (15.0%), responsibility for the safety of workers (13.3%), the risk of injury (12.4%), long-term work at the computer (10.6%). A sociological survey conducted has shown 68.9% of oil workers to consider their health status to be excellent or good. At the same time, 86.2% of respondents complain of having chronic diseases. A low healthcare activity level among oil-extraction workers has been established (73.3% of respondents do not refer to doctors, 68.9% – do not follow the recommendations of doctors, 29.7% of respondents are engaged in self-treatment). At the same time, 65.8% of oil workers believe a healthy lifestyle to help them be healthy. Limitations. A sociological study of 123 oil-extraction workers presenting a sufficient reference sample has been carried out. The limitation of this study is a high risk of subjectivity when answering the proposed questionnaire. Conclusion. Analysis of the results obtained has shown that despite a significant number of respondents were aware of the presence of hazardous occupational factors at their workplace the majority of them (89.9%) were satisfied with their working conditions. The majority of oil workers complained of having chronic diseases, although they consider their health status to be excellent and good. A low healthcare activity level of the respondents has been revealed. The results of the conducted survey have shown that the subjective assessment of oil workers’ health does not correspond to the objective data obtained during the survey analysis.

Introduction. Life expectancy is an important public health criterion. An assessment of its trend, taking into account the contribution of individual causes of death, makes it possible to form a healthcare strategy at the regional level. The purpose of the investigation was to study the contribution of individual age groups and leading classes of death causes to the trend of the life expectancy for 2005–2020, the elimination reserves of the life expectancy of the population of the Novosibirsk Region in 2020. Material and methods. The calculations were based on mortality rates by gender, five-year age groups, and causes of death from the Russian Database on Fertility and Mortality of the Center for Demographic Research of the Russian Economic School. The methods of constructing brief tables of mortality, linear approximation, and the method of components were used to calculate the contribution of spesific age groups and causes of death to the trend of the life expectancy and its elimination reserves. Results. The increase in life expectancy in the Novosibirsk region during the study period took place in 2 stages. In 2005-2009 the growth of the indicator was largely ensured by reducing the mortality of people of working age, especially men, from external causes. Further increase in life expectancy in 2009–2019 associated with a decrease in mortality of people older than working age, in particular women from diseases of the circulatory system. In 2020, the coronavirus pandemic contributed to a decline in the life expectancy for men to the level of 2015, and for women until 2011. Limitations. Territorial, temporary. The trend in the life expectancy of men and women of the Novosibirsk Region for 2005–2020 was studied. Conclusion. When developing federal, regional socio-demographic programs, and planning the work of the healthcare system, it is necessary to take into account the identified features of the trend of mortality, life expectancy, and reserves for its increase. Particular attention should be paid to increasing the availability of medical care and programs for the health-saving behaviour spesific of the population.
