BACKGROUND: Adaptation of human body to the harsh conditions of the European North remains a topic of ongoing interest, despite numerous studies on the subject. There is a need to study population groups whose daily activities involve physical activity in extreme northern conditions. One such group includes athletes who participate in endurance sports. For athletes engaged in cyclical sports, competitive activities becomes can be particularly demanding, requiring sustained physical exertion and maximum power generation. Training and competing in harsh conditions place significant strain on the body’s cardiovascular regulation mechanisms. Over time, this may result in detrimental structural and biochemical changes in the cardiovascular system. AIM: To identify the patterns of changes in heart rate regulation among track and field athletes and skiers after a training load. MATERIAL AND METHODS: Athletes from the Arkhangelsk region, including skiers and track and field athletes in the mass sports categories, who regularly compete in regional events, took part in the study. The studies took place in the medical offices of sports complexes, where the UPFT-1/30“Psychophysiologist” device was used to record and analyze cardiointervalograms. Blood pressure was recorded before and after training sessions using the Criticare System 8100H monitor. RESULTS: The initial variational span (VR) values of the duration of cardio intervals before exercise were slightly lower than the reference values in both the group of skiers and the group of athletes. At the same time, the mean square deviation (SD) values initially fell within normal range. Following the training load, both groups experienced a statistically significant decrease in SD and VR values, falling below the lower limit of the permissible range. Furthermore, spectral analysis of the cardiac intervals before exercise indicated a high level of neurohumoral regulation. After exercise, there was a statistically significant decrease in the initial values of TP in both groups, aligning with the average level of neurohumoral regulation. CONCLUSION: The results obtained in track and field athletes with a predominant anaerobic training load and skiers with a predominant aerobic load suggest that the training load of a predominantly aerobic nature may lead to less pronounced stress on the regulatory systems. This hypothesis was further supported by the results of the changes in blood pressure.

AIM: To provide an assessment of the risk of developing general toxic effects on the health of the adult population of the Arkhangelsk region associated with the consumption of wild growing mushrooms and berries. METHODS: The amount and frequency of mushroom and berry consumption by the adult population of the Arkhangelsk region were investigated through a survey (n=445 individuals). Intake doses of heavy metals contaminating mushrooms and berries were calculated for four scenarios. Hazard Quotients (HQ) were used to characterize the risk of developing overall toxic effects due to exposure to mercury, arsenic, lead, and cadmium. Hazard Indexes (HI) for substances with unidirectional effects were employed to assess the risk of non-cancerous effects on critical organs and systems. RESULTS: On average, respondents consumed 180 grams of fresh or frozen berries, 133 grams of berries with juice, and 50 grams of mushrooms in soup or boiled/fried mushrooms per week The Hazard Indexes (HI) calculated for the average consumption of mushrooms and berries and the average heavy metal contamination of wild plants were also below 1.0. However, at high levels of mushroom (P90 - 417 g/week) and berry (P90 - 900 g/week) consumption, along with high levels of heavy metal contamination, there is an increased risk of developing general toxic effects on the endocrine system (HI = 2.27), cardiovascular system (HI = 2.0), digestive system (HI = 2.0), kidneys (HI = 1.25), nervous and immune system (HI around 1.81). It is concluded that at an average contamination level, forest mushrooms and berries can be consumed without restriction. CONCLUSION: An increased risk of developing overall toxic effects on the endocrine, nervous, immune systems, cardiovascular and digestive organs has been established with high consumption of wild mushrooms and berries and at the upper limit of exposure to heavy metals.

Background: Currently, in the Arctic zone of the Russian Federation (AZRF), there are clear signs of a deterioration in the medico-demographic situation against the backdrop of a low level of development of social infrastructure. The study of the influence of living conditions, as a set of social factors of the habitat, formed by social infrastructure, on the mortality rates of the population of one of the AZRF regions, was carried out for the first time. Aim: To assess the impact of living conditions, as a set of social factors of the habitat, on the mortality rates of the rural and urban population of the Nenets autonomous okrug (NAO) in the period 2000-2019. Materials and methods: The databases “Housing and communal services and social infrastructure in NAO in 2000-2019” and “Death cases in NAO in 2000-2019” (including information on the population number and age-sex structure) of the NAO population in the context of individual settlements have been generated. Using the developed scoring system for assessing living conditions, a ranking (division into tertiles) of all rural NAO settlements was carried out according to the value of the integral index of living conditions (IILC). A comparative analysis (tertiles with the city, and tertiles with each other) of average annual age-standardized rates of overall mortality, mortality from the main causes and structural components of external causes (EC) of mortality was carried out. Relative epidemiological risks were calculated as the ratio of mortality rates in each tertile to the corresponding indicator for the urban population. Results: Average annual standardized rates (and relative risks) of mortality (total, EC, drowning, freezing, alcohol poisoning and transport accidents) of the NAO population “step by step” increase in the sequence “city - highest tertile - middle tertile - lowest tertile”, i.e. as living conditions worsen (as the IILC decreases). Statistically significant differences were identified between the city and tertiles, as well as between the highest (“favorable” living conditions) and lowest (“unfavorable” living conditions) tertiles in terms of total mortality, mortality from EC, drowning and freezing. Mortality rates from alcohol poisoning and transport accidents also increase (but not statistically significant) as living conditions worsen. With the exception of suicides, the relative risks of mortality for individual EC reach maximum values in the lowest tertile. Conclusion: Statistically significant inverse relationships have been identified between rates of total mortality, mortality from external causes (and its main structural components), and the values of the integral index of living conditions of the rural NAO population: as living conditions worsen, mortality rates (and relative risks) increase.

BACKGROUND: Analysis of the dependence of the morbidity of the rural population on various environmental factors will allow us not only to assess the level of social and demographic problems in the regions of the Russian Federation, but also to determine the directions for the development of state regional policy to achieve national development goals. AIM: Determination of the determinants of the morbidity rate of the rural population in the Russian Federation, including the main classes of diseases, among environmental factors in the context of the COVID 19 pandemic. METHODS: The initial data for the study were materials from the Federal State Statistics Service, as well as statistical materials from the digest “Rural Healthcare in Russia in 2021”, provided by the Federal State Budgetary Institution “Russian Research Institute of Health” of the Russian Ministry of Health. The following methods were used in the research process: Pearson correlation, factor analysis (principal component method), hierarchical cluster analysis, multiple linear regression (elimination method). Calculations were performed in the STATISTICA 10 system (StatSoft, USA). Results. Six typological groups of regions of the Russian Federation were distinguished. They differ in the morbidity rate of the rural population by the main classes of diseases: some infectious and parasitic diseases, neoplasms, diseases of the circulatory system, diseases of the respiratory system, digestive system, and some consequences of external causes. It has been established that there is differentiation in the regions of the Russian Federation according to the factors influencing the morbidity rate of the rural population by the main classes of diseases during the COVID 19 pandemic in 2021. It has been shown that the state of the healthcare system and medical and social factors have the greatest impact on the overall morbidity rate in the regions of the fourth and fifth classification groups, on the detection of some infectious and parasitic diseases in the regions of the second, fifth and sixth groups, and respiratory and digestive diseases in the third classification group. The housing quality in the regions of almost all groups is one of the most significant social factors. Economic conditions have a significant impact on the incidence of certain infectious and parasitic diseases in the regions of the third and sixth groups, as well as on the level of injuries and some consequences of external causes in the regions of the first and third groups. Environmental factors are significant in the regions of the fifth group. At the same time, regression dependencies on selected factors for all classification groups of regions of the Russian Federation were obtained only for some infectious and parasitic diseases.

BACKGROUND. One of the main threats to national security in the Arctic today is the reduction in the population of the Arctic zone. A decrease in population over the last decade has also been observed in the Arctic zone of the Republic of Sakha (Yakutia). It is clear that this situation is mainly due to unfavorable medical and demographic processes: low birth rates, relatively high mortality rates in the 13 uluses included in the Arctic group. As our research has shown, low levels of marriage in most of the Arctic uluses examined also contribute. AIM. Analysis and assessment of the dynamics of marriage and divorce rates in the Arctic zone of the Republic of Sakha (Yakutia) for the period 2000-2022. MATERIAL AND METHODS. The analysis was based on materials from official government statistics. Initially, the levels of indicators for marriages and divorces were calculated using the percentile method in all regions/uluses of the republic, then the analysis was continued for a group of 13 Arctic uluses. RESULTS. It turned out that both marriage and divorce rates were relatively low in the selected group, which is clearly confirmed by the tables and charts presented. Calculations of correlation coefficients between marriage and birth rates showed their logical connection. CONCLUSION. Relatively low marriage and divorce rates worsen the already unfavorable medical and demographic situation in the Arctic regions of the republic. To improve the situation in the field of demographic policy, appropriate recommendations were given to the heads of municipalities of the Republic of Sakha (Yakutia).

Purpose This study assessed anthropometric changes developed by schoolchildren from the indigenous population of the Magadan Region in the age aspect. Materials and Methods Two hundred and eight boys and one hundred and ninety girls from the native indigenous nations (Evens, Koryaks, Itelmen) participated in the 2021-2023 Anthropometric Survey. They accounted for 67.2% of all schoolchildren surveyed (592 people in total). According to generally accepted research methods, the following indicators were measured: body height (BH), body mass (BM), chest circumference (CC), sitting height (HSit), right and left hand strength. To assess the subjective physical development, we calculated annual gains in weight and height indices, as well as proportional physique and its strength. Results In the age dynamics from 8 to 17 years, we could see a natural increase in the absolute body indicators of BH, BM, HSit, CC, and right and left hand strength. The rate of annual growth indicated different timing of the periods of pronounced gains in the body parameters. Girls exhibited a CC maximum increase at 10-11 years old with simultaneously raising BH, BM, HSit, and muscle strength indicators at 11-12 years old. During the same age periods, boys showed a pronounced BH growth with BM with CC gaining at 12-13 years of age. After a slight attenuation in the growth rate, we could observe a BH jump occurred at the age of 14-15, which was caused by gender aspects in older children groups. Sex-related characteristics of BH growth rates are primarily associated with differences in the body limbs (legs) growth rates during the puberty, and tend to be higher in boys. In general, rather weak physique with a predominance of asthenic somatotype was characteristic of the examined boys. A proportional body type with high percentage of those with relatively short legs was more common in the examined girls. Conclusion The results obtained have provided us with evidence on a better level of physical development and the body adaptive adjustments exhibited by girls compared to boys.

During the same age periods, boys showed a pronounced BH growth with BM with CC gaining at 12-13 years of age. After a slight attenuation in the growth rate, we could observe a BH jump occurred at the age of 14-15, which was caused by gender aspects in older children groups. Sex-related characteristics of BH growth rates are primarily associated with differences in the body limbs (legs) growth rates during the puberty, and tend to be higher in boys. In general, rather weak physique with a predominance of asthenic somatotype was characteristic of the examined boys. A proportional body type with high percentage of those with relatively short legs was more common in the examined girls. \u0000Conclusion The results obtained have provided us with evidence on a better level of physical development and the body adaptive adjustments exhibited by girls compared to boys.","PeriodicalId":38121,"journal":{"name":"Ekologiya Cheloveka (Human Ecology)","volume":" 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141129547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
BACKGROUND: Climate change has a significant impact on the population health including morbidity and mortality. The studies presented in this paper present characteristics of heat and cold waves on the Crimean Peninsula. AIM: To assess the heat and cold wave characteristics, identify differences in the wave characteristics depending on the coastal and mainland location of climatotherapeutic centers on the Crimean Peninsula. MATERIAL AND METHODS: In our research we used standard statistical data treatment methods. Moreover, data visualization techniques allowed identifying zones of maximum temperature values. Heat and cold waves were defined using the 3rd and the 97th percentiles of the average daily air temperatures. This approach allows considering the intensity and duration of the events under study. Measurements of the surface air temperature included eight observations per day at 19 stations on the Crimean Peninsula for the period from 2006 to 2021. Distribution of the permanently residing population in the Crimea and the city of Sevastopol by age and gender was analyzed using the Rosstat data. RESULTS: As many as 43.5% of the population of the Crimean Peninsula have increased risk of exposure to extreme air temperatures. Having applied the threshold values of the 3rd and the 97th percentiles of the temperature, we identified the periods of heat and cold waves at each station. Even though the Crimean Peninsula has a warm and humid climate, 1 to 4 cold and heat waves have been observed at each station per year. At the same time, the total intensity of cold waves was more than twice the total intensity of heat waves. CONCLUSION: The presented assessment of heat and cold wave characteristics on the Crimean Peninsula, using 3% and 97% percentiles of the distribution of the average daily air temperature over several years, provides the evidence for developing the measures to reduce the negative impact of extreme temperatures on human health on the Crimean Peninsula.

Aim Hygienic assessment of the dietary intake of aluminum in the body of the adult population of the region of Western Siberia. Materials methods The studies were conducted in 2019-2020 among the adult population of the Omsk region. The aluminum content in the human body was evaluated in 240 people.The actual intake of aluminum with food products was assessed in 421 adult residents of the region using a questionnaire on the frequency of food consumption. Results In 33.13.9% of the population, the content of aluminum in the body was higher than the reference values. Significant differences in the content of aluminum in the body of the population of different age-sex groups have not been determined (p=0.200). The median daily intake of aluminum was 4.77 mg/day. (3.679; 6.118). The main contribution to the intake of aluminum with food products was made by: "Drinks", "Vegetables", "Bakery products", among individual products - tea and bread. An increase in the contribution of vegetables and a decrease in the contribution of confectionery products to the intake of aluminum with an increase in the age of the population was noted. Discussion The median intake of "edible" aluminum in the adult population of the Omsk region did not exceed TWI, as well as PTWI, and corresponded to world data on the average level of aluminum intake into the human body. Conclusion An increase in the proportion of the population with a high content of aluminum in the body requires in-depth toxicological, hygienic and epidemiological studies.

BACKGROUND: Aridization of the southern territory increases the concentration of toxic substances in Russia in groundwater in the long-term future. AIM: To analyze the potential of a multi-regression climate model to predict long-term dynamics of health risks associated with the oral release of toxicants from groundwater. METHODS: An assessment of non-carcinogenic health risk (HI) was carried out for the period 2017-2022 within the occurrence of three groundwater basins in the Volgograd Trans-Volga region. Concentrations of toxicants were analyzed in 1149 water samples at the 95th percentile. NDMI and the De Martonne Index (DMI) values were calculated. DMI inputs data was modified using LST (Land Surface Temperature) satellite analysis. In the models, HI served as the dependent variable with NDMI and DMI values used as predictors. RESULTS: A significant contribution of chloroform to the overall risk pattern for groundwater in the Volgograd Trans-Volga region was discovered. The maximum values were recorded in the Nizhnevolzhskiygroundwater basin (HQchildren/chloroform=3.20, HQadults/chloroform=1.37) in 2017. The satellite aridity index NDMI makes the greatest contribution to the reliability of the predictive model of long-term health risk dynamics that shape the oral intake of pollutants from groundwater in the Volgograd Trans-Volga region. The lowest multiple regression value was noted for the health risk for adults (ry,x1,x2=-0.909, p=0.012) in the Severo-Prikaspiyskiy basin, the maximum was recorded in Ryn-Peskovsky basin for children (ry,x1,x2=-0.992, p= 0.002) ). The De Martonne climate index provides insignificant reliability in predicting long-term dynamics of non-carcinogenic health risks associated with toxicants circulating in arid ecosystems of the South of Russia - the largest contribution of this predictor for the health risk of children in the Ryn-Peskovsky basin (rx2/x1=-0.554, p=0.105). CONCLUSION: A potential of NDMI integration in the social and hygienic quality monitoring of underground water arid zones of southern Russia has been identified. The high resolution and sensitivity to water quantity in steppe vegetation confirms the accuracy of the NDMI indicator for arid topography.
