LEAD CONCENTRATION IN HUMAN HAIR IN THE ADMINISTRATIVE CENTER OF THE ALTAI REPUBLIC
Chanchaeva E.A., Sukhova M.G., Kurilenko T.K.
Abstract
Background: Liquid and solid fuels are the main source of lead (Pb) in urban settings. Some household items have also been identified as sources of lead. Thus, monitoring of this trace element in humans remains an important public health issue. Aim: To assess concentration of lead in hair of residents of Gorno-Altaisk city - the administrative center of the Altai Republic and to estimate the proportion of the population with high hair concentration of lead. Methods: Hair samples were collected from 122 (50.8 % men) neither smoking nor taking mineral supplements healthy permanent residents of Gorno-Altaisk aged 4-50 years. Fifty-three percent of them lived in the central part of the city. Concentration of led in the hair samples was estimated by atomic absorption method. Differences in average concentrations across genders, age-groups and locations were studied using Mann - Whitney tests. Associations between continuous variables were studied by non-parametric correlation analysis. Results: The average lead hair concentration in Gorno-Altaisk was 3.18 mg/kg which exceeds the values previously reported from other Russian settings (0.5-3.0 mg/kg). Twenty-six percent of residents had hair concentration of lead above the maximum allowed level of 5.0 mg/kg. Hair lead concentration positively correlated with age (r = 0.54), but was not associated with either gender or place of residence. Conclusions: Average concentration of led in human hair in Gorno-Altaisk is high, but it does not exceed the maximum allowed level. More than every fourth resident of the city has hair lead concentration exceeding biologically acceptable level. We found significant associations between hair lead concentrations and age, but not with gender or place of residence.

VITAL STATISTICS AND THE CROW INDEX AMONG THE INDIGENOUS POPULATION OF THE REPUBLIC OF SAKHA (YAKUTIA)
Danilova A.L., Sukhomiasova A.L., Yakovleva A.E., Maksimova N.R.
Abstract
Introduction: Natural selection in humans is influenced by genetic and environmental factors. It can be assessed using selected genetic and demographic parameters, namely, vital statistics, the Crow index, or the total selection index and its components. Aim: To study vital statistics and the Crow index among post-menopausal indigenous women in the Republic of Sakha (Yakutia) living in different economic zones. Methods: The sample consisted of 347 post-menopausal indigenous women from 15 districts of the Republic of Sakha (Yakutia). The districts were merged into Central, Arctic, and Western regions. The Crow index and its components was calculated. Regional variations in the studied characteristics were assessed using nonparametric Kruskal-Wallis test. Results: We observed statistically significant differences in the reproductive indicators across the regions. The lowest pressure of natural selection (Itot) was experienced by the ethnic minorities from the Arctic region (0,407) compared to the Yakuts (0,395) from this region and their counterparts from the Central (0,407) and Western (0,457) regions. Conclusions: Despite wide spread of family planning the indigenous ethnic groups of the Republic of Sakha (Yakutia) demonstrate high fertility. In all studied groups, the component associated with differential fertility exceeds the component associated with differential mortality. Economic, social, and cultural factors significantly influence reproductive patterns.

BRAIN ACTIVITY IN ADOLESCENTS WITH DIFFERENT INTERNET ADDICTION RISKS
Demin D.B.
Abstract
Aim: To study electroencephalographic (EEG) changes in adolescents with different risks of developing Internet addiction (IA). Methods: This cross-sectional study included 1б-17 years-old adolescents (n = 55) permanently living in the Arctic Russian town of Arkhangelsk. Risk of IA was assessed using the Chen Internet Addiction Scale (CIAS). By the results of the CIAS test all adolescents were divided into three groups: I - minimal risk of IA, II - increased risk to develop IA and III - stable IA pattern. EEG was evaluated by the values of spectral power (|jV2) in each frequency band. Results: Altogether, 25.5 % of adolescents had minimal risk of developing IA, б3.б% belonged to group 2 and 10.9 % had IA. The organized type of alpha activity EEG was found in 79 % of individuals in group I and in 100 % of individuals in group III. This indicates the optimal age ratio of the activity of the reticular formation, cerebral cortex and diencephalic structures. A large number of negative correlations between compulsive symptoms of IA and all types of EEG activity in group I was determined, which may indicate a resistance of these individuals to addiction. The organized EEG type was detected in 54 %, hypersynchronous type - in 14 %, desynchronized type - in 14 %, disorganized type - in 18 % of group II individuals. A disorganized EEG type with a large ratio of theta EEG waves in the frontal-central brain parts in group II may indicate a high limbic-diencephalic excitation. The correlations between the indicators of the withdrawal symptom scale and the EEG theta-activity reflect the psychological discomfort when access to Internet resources is difficult. Conclusions: Most adolescents with minimal risk of IA and symptoms IA have an organized EEG-type while adolescents with IA have this EEG-type only in a half of the cases, which is caused by the heterochronia of the EEG formation in the Arctic residents and the peculiarities of the formation and development of IA.

LIFE EXPECTANCY IN THE SIBERIAN FEDERAL DISTRICT AND IN THE IRKUTSK REGION IN 1990-2018: TRENDS AND PECULIARITIES
Leshchenko Y.A., Lisovtsov A.A.
Abstract
Introduction: Life expectancy is widely used as an indicator of socio-economic development of territories and public health in general. Aim: To study secular trends and peculiarities of life expectancy in the Irkutsk region and in the Siberian Federal District from 1990 to 2018. Methods: Data on life expectancy for all regions included in the Siberian Federal District (Siberian FD) were obtained from Rosstat and from the Center for Demographic Research of the Russian School of Economics. Linear regression was applied to study trends in life expectancy. Results: There was a consistent improvement in the demographic situation in Russia 2006 to 2018 caused by decreasing mortality and increasing life expectancy. On the national level, life expectancy increased from 66.7 to 72.9 years. The corresponding data for Siberian FD were 64.6 and 70.7 years while in the Irkutsk region the increase was from 62.9 to 69.3 years. Similar patterns were observed in all FDs, but the improvements in the demographic indicators were less pronounced in the Eastern regions of the country. Life expectancy in the Irkutsk region and the Siberian FD remained lower compared to other FDs except for the Far Eastern District over the study period. Significant linear increase in life expectancy was observed in regions with coefficient of determination ranging from 0.960-0.989, p < 0.001 for all tests. In 2018, the annual increase in life expectancy dropped from 0.3-0.9 to 0.1-0.2 years. Conclusions: Our findings suggest less favorable state of public health in the Siberian FD and in the Irkutsk region compared to the other FDs and the national average. These findings are in line with the conclusions from earlier studies performed by the authors about lower quality of the life of the population in Siberia than in Russia in general.

WEATHER FACTORS AND AMBULANCE CALLS FOR RESPIRATORY CAUSES IN THE CITY OF PETROZAVODSK
Rybakov D.S., Belashev B.Z.
Abstract
Aim: To study associations between selected weather factors on the number of ambulance calls for selected respiratory diseases in the city of Petrozavodsk, Northwest Russia. Methods: Data on the number of ambulance calls in the city of Petrozavodsk were obtained for the period from 2015-2017. Associations between weather factors and the number of ambulance calls for respiratory diseases were studied by correlation analysis. Pearson's correlation coefficients were calculated. Separate analyses were performed for acute upper respiratory tract infections (J06), viral pneumonia (J12), acute bronchitis (J20) and asthma (J45). An additional analysis was performed for the warm- (14 months with the mean monthly temperature from +9.8 to +18.4 °C) and the cold (22 months with a temperature from -14.9 to +5.0 °C) seasons. Results: The overall number of ambulate calls for viral pneumonia decreased during the study period. Significant associations between air temperature and atmospheric pressure and the number of calls for respiratory deceases, particularly for acute respiratory tract infections. During the cold season the influence of the temperature factor on the number of calls decreased for the most cases except acute bronchitis. The lowest number of calls for acute bronchitis was observed during summers. In summer, the number of calls for acute bronchitis was positively associated with wind speed and inversely associated with mean temperature and humidity. The number of calls for acute respiratory infections was positively associated with intraday increase in barometric pressure and wind speed. In autumn, significant correlations were observed between the North-West wind, which carries air pollutants from the industrial part of the city to the residential area and the number ambulance calls. In winter, an inverse association between humidity and ambulance calls for viral pneumonia was found. In spring, significant associations between the number of ambulance calls for several respiratory causes and cloudiness were observed. Conclusion: Significant associations between weather factors and the number of ambulance calls for respiratory causes were observed in the city of Petrozavodsk. Our results can contribute to better planning of ambulance services in town.

ECOLOGICAL FACTORS ASSOCIATED WITH FLUCTUATIONS IN THE INCIDENCE OF NEOPLASMS IN CHILDREN
Pinaev S.K., Torshin V.I., Radysh I.V., Chizhov A.Y., Pinaeva O.G.
Abstract
Introduction: Despite the increasing volume of knowledge on oncogenesis, the year-to-year fluctuations in the incidence of neoplasms remain poorly explained. Neoplasms in children <5 years have primarily prenatal origin. However, the number of studies form Russia on this topic is limited. Aim: To study associations between fluctuations in the incidence of neoplasms among children <5 years and selected environmental factors (EF). Methods: Firstly, we studied associations between the overall incidence of malignant- (MT) and benign tumors (BT) in the 11 cohorts of under 5 children born in 1976-1986 in the city of Khabarovsk using Pearson's correlation coefficients with lags from -3 to +3 years. Secondly, we studied correlations between specific forms of BT and MT with EF in the 17 cohorts in the Khabarovsk region. Thirdly, we assessed correlations between solar activity and the incidence of non-Hodgkin lymphomas (NHL) in 0-14 years old children 0-14 in Russia over 22 years (1997-2018). Results. An inverse correlation (r = -0.705, p = 0.015) was observed between the incidence of BT and MT in cohorts 1 year older suggesting that their fluctuations were in an antiphase. In cohorts with greater incidence of BT the incidence of MT was lower and vice versa. Significant correlation between the solar activity with lag 1 and the incidence of non-Hodgkin lymphomas (NHL) was observed in the 17 cohorts of children in the Khabarovsk Territory (r = 0.644, p = 0.032). Corresponding correlation coefficient for the 0-14-year-old children using national data was 0.621, p = 0.010 with a lag of 5 years. Conclusions. Annual fluctuations in the incidence of BT and MT are unlikely to be completely sporadic. An inverse association between the incidence of BT and the incidence of MT was observed potentially reflecting an alternative scenario of oncogenesis in these diseases influenced by a constellation of environmental factors.

ASSOCIATIONS BETWEEN THE CHARACTERISTICS OF LARGE NATIONAL REGIONS, INDIVIDUAL ALCOHOL CONSUMPTION AND TOBACCO SMOKING: A SYSTEMATIC REVIEW PROTOCOL
Maksimov S.A., Tsygankova D.P., Danilchenko Y.V., Shalnova S.A., Zelenina A.A., Drapkina O.M.
Abstract
Introduction: Tobacco smoking and hazardous alcohol consumption significantly contribute to the burden of diseases worldwide. Characteristics of the environment has been consistently shown to be associated with the patterns of tobacco smoking and alcohol consumption patterns. This evidence has been previously summarized on country- and neighbourhood-level reviews although the evidence on the associations on the regional level is still scarce. Aim: to present a protocol of the systematic review of available evidence on the associations between certain characteristics of large national regions and alcohol consumption and tobacco smoking. Methods: A systematic search of PubMed, Google Scholar, OpenGrey, CrossRef, and eLibrary) will be conducted to identify original studies with no date or language restrictions. Only studies with territorial characteristics as exposure variables and with tobacco smoking and alcohol consumption as the outcomes will be selected. The studies have no restrictions regarding participant characteristics, that is, gender, age, socioeconomic criteria, or health status. Titles, abstracts, and full text of articles retrieved from the search will be screened and read independently by two reviewers for eligibility. Articles selected for inclusion will be critically and independently appraised by two reviewers. The full-text of the selected studies will be assessed in detail, and findings and their illustrations will be extracted and aggregated. Any disagreements between the reviewers that may arise at any stage will be resolved through discussion, or mediated by a third reviewer. Systematic review registration number: PROSPEROCRD42021234874.
