Evaluation of incidence of organized team members under environmental and hygienic load and unfavorable labor
Bioclimatic comfort, anthropogenic load, conditions and nature of the labor process, lifestyle are among the main factors of the environment and professional activities of people. Purpose - to assess the incidence of persons of an organized team in the ecological and hygienic conditions of the city of Krasnoyarsk. Object - prevalence, primary incidence for the period 2016-2021. The state of anthropogenic pollution of the city territory was judged according to official sources. Assessed the working conditions and the nature of the labor process. The chemical load defines Krasnoyarsk as one of the leaders in the total morbidity of the region and as a risk area in the region in terms of morbidity exceeding the average. Uncomfortable living environment is noted for 9-10 months. The work of the observation group according to the degree of harmfulness and danger - class 3.3. In the structure of work, 80% of the time is mental [intellectual loads (3.2), emotional loads (3.2), work schedule (3.2)], physical activities, periodic long business trips with high emotional and physical stress. In the lifestyle of eating disorders, drinking alcohol, smoking. The prevalence of diseases was 1.6 times higher than in the adult population of Krasnoyarsk and (or) the region: a significant excess of 1.35-4.8 times in 6 classes and lower values of 1.2 times in 2 classes of diseases. In the primary morbidity, the leading pathologies were respiratory, genitourinary, musculoskeletal, trauma and poisoning (including the consequences of external causes), hearing aid, the share of which in the structure reached 80.3%. With the exception of the pathology of the hearing aid, it reflected the incidence of the adult population of the Krasnoyarsk Territory, as well as the dynamics of long-term morbidity. The peculiarities of morbidity in a cohort of an organized team are determined by their initial state of health, conditions of professional activity and lifestyle. The need to assess the health risk of the influence of synergistic factors of habitability of the population is actualized, taking into account the characteristics of professional activity and lifestyle.

Assessment of lipid spectrum and C-reactive protein in people working in the Arctic zone of Russia
Adaptation to the extreme living conditions of the North causes dyslipidemia, a risk factor for cardiovascular diseases (CVD), in people working there. This study aimed to assess the level of lipids and C-reactive protein (CRP), a marker of inflammation in CVD cases, in the blood of men staying in the Arctic and Subarctic zones of Russia. Accordingly, the sample was divided into two group, Arctic and Subarctic, the former included 51 participants, aged 35.7 ± 0.6 years, the latter — 54 individuals, aged 34.2 ± 0.9 years (p = 0.167); the duration of their work/stay in the Arctic and Subarctic zones was 7.1 ± 0.2 and 6.4 ± 0.6 years (p = 0.447), respectively. We sampled blood of the participants and measured triglycerides, total cholesterol, low (LDL) and high (HDL) density lipoproteins, atherogenic index (AI), CRP content. Arctic group had higher levels of triglycerides (1.71 ± 0.03 and 1.38 ± 0.14 mmol/l, p = 0.021), total cholesterol (6.15 ± 0.08 and 5.47 ± 0.14 mmol/l, p =0.001), HDL (1.5 ± 0.06 and 1.1 ± 0.04 mmol/l, p = 0.001); the values of LDL did not differ significantly between the groups (4.07 ± 0.08 and 4.1 ± 0.15 mmol/l, p = 0.88), and AI and CRP values (3.41 ± 0.18 and 4.18 ± 0.2, p = 0.007; 3.41 ± 0.18 and 4.91 ± 0.22 mg/l, p = 0.006, respectively) were greater in the Subarctic group. By triglycerides, dyslipidemia was diagnosed in 49.0% and 18.4% of Arctic and Subarctic participants, respectively, by total cholesterol — in 98.0% and 57.8%, by LDL — in 94.1% and 88.0%. As for HDL, their level was lower than normal in 2.0% of the Arctic group subjects and 36.7% of the Subarctic group subjects, which means a higher risk of cardiovascular diseases in the Subarctic region. The level of CRP indicated that 90% of the Arctic group participants were at risk of CVD (moderate risk for 23.5%, high risk for 66.7%), and in the Subarctic group this number was 100% (moderate risk for 7.7%, high risk for 88.5%). The likely reasons behind this are the specifics of nutrition and living conditions. Program of prevention of CVD in the Arctic zone should include lipid profile and CRP tests as part of every periodic medical examination, regardless of age. It is necessary to implement dyslipidemia alimentary correction measures.
Introduction. In recent years, the UTCI bioclimatic index has been used to assess the impact of climatic conditions on health. Goal is an assessment of the morbidity in persons of an organized team in the Arctic to determine the health risk when working in an open area. Materials and methods. According to the data of temperature, wind speed, relative air humidity on Dikson Island and Cape Chelyuskin the UTCI indices were calculated for 2009-2019. The health risk was assessed by the degrees of cold stress. We retrospectively estimated the prevalence of diseases, including primary morbidity, in 25-45 years persons over 2015-2020 by general and by classes of diseases. Results. In terms of severity, cold risk was characterized from severe to extreme stress. According to the prevalence of diseases, 76.5% of the total population accounted for 6 classes of diseases according to ICD-10 included respiratory, genitourinary, endocrine systems, nutrition disorders and metabolic disorders, musculoskeletal system and connective tissue, digestive organs, circulatory system. In the structure of morbidity according to primary appeal, 79.5% according to ICD-10 accounted for diseases of the respiratory system, genitourinary system, musculoskeletal system and connective tissue, injuries and ear diseases. During long-term observation in the prevalence of diseases, the incidence of injuries increased, according to primary data - diseases associated with mental disorders, damage to the nervous system, skin diseases and diseases of the subcutaneous tissue, injuries. Limitations. The results obtained require verification in age-standardized cohorts; in various gender groups and groups working in organized and unorganized teams, as well as in various internship groups. Conclusion. According to UTCI, health risk in the Arctic was assessed as cold stress including severe (3-4 months), very severe (2-3 months) and extreme (5-6 months). Morbidity for current classes of diseases indicates both the impact of the climate of the Arctic on the health of people in an organized team, and working conditions.
