The sample consisted of 1,516 people aged 18 years and older who were interviewed at their place of residence. The results were compared with the findings of previous surveys of the same design.\u0000Result: The study has demonstrated a decrease in the proportion of Russians who believe that they lead a healthy lifestyle (from 63.7 % in 2021 to 56.2 % in 2023). At the same time, only 13 % of the respondents were found to adhere to basic principles of a healthy lifestyle. Male sex, having no higher education, and low income were associated with a poor commitment to the latter. We have noted a rising trend in the prevalence of smoking among young people. In the group of 18–24-year-olds, we observed a 1.5-fold increase in the proportion of smokers over the previous year related to the growing popularity of vaping. We have also established an increase in consumption of energy drinks (from 16.6 % in 2013 to 22.8 % in 2023), especially among young people aged 18–24 (53.2 %).

Our objective was to assess the dynamics of risk factors in people with different health status and the role of healthy \u0000lifestyle recommendations in lifestyle changes.\u0000Materials and methods: The first stage of the study was conducted in 2016 and included 1,600 respondents while the second was in 2019 involving 991 respondents, which were then divided into three groups by their health status: apparently healthy, those who developed an atherosclerotic cardiovascular disease (CVD) during the observation period, and those already sick (initial CVD cases). The participants were examined and surveyed for the main cardiovascular risk factors, such as blood pressure, cholesterol, including its atherogenic lipoprotein, smoking, body mass index, and past illnesses. Lifestyle \u0000modification following the receipt of healthy lifestyle recommendations was assessed by survey.\u0000Results: The most pronounced dynamics of risk factors was revealed among those who developed a CVD in the course of observation: cholesterol decreased from 5.7 to 5.2 mmol/L, p = 0.005, its atherogenic lipoprotein – from 4.3 to 3.4 mmol/L, p < 0.001, systolic blood pressure – from 144 to 128 mmHg, p < 0.001, and the body mass index – from 30.8 to 30.7 kg/m2, p = 0.255. Most patients from this group (59.3 %) received healthy lifestyle recommendations and the proportions of those who followed them and modified their lifestyle were higher than in other groups (39.0 % and 54.7 %, respectively; p < 0.001). \u0000In the group of apparently healthy individuals, lifestyle recommendations were given to 27.4 % members; yet, this group was noted for a high prevalence of lifestyle self-modification (23.8 %).

The complex load was estimated in accordance with method guidelines MR 01-19/17-17. \u0000Results: We established that pollution of ambient air in residential areas contributed the most (69.8 %) to the total anthropogenic load in the town Pavlovsk; drinking water – to that in the Semiluksky district (36.5 %), and soil – in the Rossoshansky district (10.5 %). In the city of Voronezh, the level of complex anthropogenic load exceeded both the regional \u0000and district averages. The problem of ambient air pollution dominates in all districts; it should be noted, however, that air sampling is carried out only in urban areas and urban-type settlements. In rural areas, effects of agriculture-associated nitrate pollution of drinking water is more pronounced. The impact of soil pollution is more pronounced in urban residential areas. At the same time, the excess of maximum permissible concentrations of soil pollutants were registered neither in rural nor in urban areas over the study period.\u0000Conclusion: In Voronezh, the level of complex anthropogenic load exceeds the average values estimated for the region and districts.

Trace element deficiency is a challenge in northern regions, where acclimatization-related lack of many essential elements is aggravated by adverse health effects of a combination geochemical and anthropogenic factors. Objective: To establish relationships between the elemental profile of the body and some psychophysiological characteristics of young residents of the continental part of the Magadan Region as a model presumably healthy part of the population. Materials and methods: Fifty-five lyceum students, including 25 girls and 30 boys (mean age = 17.6 ± 0.25 years), living in the town of Susuman, Magadan Region, were examined. Concentrations of 25 trace elements (Al, As, B, Be, Ca, Cd, Co, Cr, Cu, Fe, Hg, I, K, Li, Mg, Mn, Na, Ni, P, Pb, Se, Si, Sn, V, and Zn) were measured in hair samples of the subjects using inductively coupled plasma atomic emission spectrometry (ICP-AES). Psychophysiological indicators were examined using the NS-Psychotest hard & software unit. The I.N. Gurvich questionnaire was applied to study neuropsychic adaptation (NPA) and anxiety levels were determined using the Spielberger-Hanin test. Results: The correlation analysis showed the highest number of links between lithium and psycho-functional variables in all students, which is consistent with the opinion of experts on the role of this element in reducing neurological manifestations, stress, and depression. The female group demonstrated relationships between the indicator of situational anxiety and those of the functional state of the central nervous system: functionality level (r = –0.56), reaction stability (r = –0.63), and functional ability level (r = –0.61), p < 0.01.
