Health of children and adolescents largely depends on the quality of their sleep. However, the effect of digital devices and screen time on thereon have not been studied thoroughly. This study aimed to investigate the influence of digital devices on the sleep quality of primary school children. We surveyed 333 parents of children aged 7–10 years. The questionnaire included questions about the types of digital devices used by children, and frequency and duration of use daily and weekly use. We studied the specifics and quality of sleep of children. It was found that using a laptop for more than an hour a day increases the risk of sleep disorders (RR = 1.87; 95% CI: 1.37–2.54; EF = 46%). Children using a computer every day run a higher risk of nightmares (RR = 4.7; 95% CI: 1.49–15.11; EF = 79%). Neither TV, nor mobile phones were shown to produce such effects. The study has revealed that the type of the device and the patterns of its use (on both daily and weekly levels) are factors in the development of sleep disorders.

Radioactive and chemical contamination can affect carcinogenesis, including the development of malignant neoplasms of the ovaries (MNOs) in women. The study aimed to perform comparative assessment of environmental situation in the towns and districts of the Bryansk Region based on chemical, radioactive, and combined radioactive contamination, as well as primary incidence of MNOs in women in accordance with official statistics for the years 2000–2019. The data for the study were provided by the Bryansk Regional Oncology Dispensary, Bryanskstat, Rostekhnadzor, Rospotrebnadzor. Neither significant differences in primary incidence of MNOs, nor increased risk of MNO were revealed in female population aged 18–80 years, regardless of the environmental conditions of living in 2000–2019. We revealed a significantly elevated relative risk (RR) of primary incidence of low-grade MNOs in women aged 41–60 years living in the environmentally disadvantaged areas compared to women living in the control areas: RR 1.88 (95% CI: 1.43–2.48); p < 0.0001). The rate of low-grade MNOs in women aged 41–60 years in the areas of the combined exposure is 17.6 ± 1.96, which 1.5-fold exceeds the values reported for radioactively contaminated areas (11.7 ± 2.73) and 1.2-fold exceeds the values reported for chemically contaminated areas (15.2 ± 1.31). The combined effects of radioactive and chemical contamination results in the higher RR of low-grade MNOs compared to the areas with only one pollution factor, i.e. radioactive contamination (RR 1.51 (95% CI: 1.00–2.28)), chemical contamination (RR 1.17 (95% CI: 0.90–1.50)). The findings suggest synergistic effect of radiation and chemical factors on the incidence of low-grade MNOs.

Drinking water occupies one of the leading places among environmental factors responsible for shaping public health, so providing sanitary-and-epidemiologic wellbeing of the population cannot be considered separately from solving the hygienic problem of water supply. The study aimed to provide comparative hygienic characteristics of the quality of drinking water from the Ryazan centralized water supply system based on organoleptic indicators. Comparative assessment of the quality of drinking water was performed based on the analysis of the data of the years of research for the years 2017–2022. We performed analysis of the long-term average annual values of odor at 20 ºС and 60 ºС, taste, color and turbidity, share of samples non-compliant with the hygienic standards, over time. Inidicators were also assessed based on the season of the year and territorial belonging. The average indicator values were compared using analysis of variance; pairwise comparison involved the use of the Scheffe and Tamhane tests considering the Levene’s test results. Confidence intervals of the relative indicators were determined based on the Wilson score. The long-term average annual values of organoleptic indicators of the quality of drinking water in Ryazan are compliant with SanPiN 1.2.3685-21. A small number of samples had odor, taste, and color exceeding the hygienic standards. Turbidity that was non-compliant with the hygienic requirements in 2.2% of samples and reached the maximum value of 16.4 mg/L (kaolin) should be considered the most challenging indicator of the quality of test drinking water.

Current approach to sanitary and hygienic measures in various parts of the national health care system should create new challenges aimed at practical prevention in the context of the safety of people from the environmental carcinogenic factors. The effective Russian SanPiN 1.2.3685-21 regulates hygienic requirements for the safety of environmental factors for humans; inter alia, the documents lists biological carcinogens and carcinogenic lifestyle factors. The efforts of sanitary specialists in general and employees of Rospotrebnadzor in particular aimed at prevention of harmful impact of the existing carcinogenic factors shall be more effective if the available information on the potentially dangerous biological agents of carcinogenesis is more complete. This paper reviews the modern sanitary and hygienic aspects of carcinogenic factors of biological nature, and describes the causes of oncological diseases caused by them as well as the respective prognosis. Viruses, bacteria and trematodes, whose participation in the occurrence and development of a specific cancer is an established fact, are posed as etiological agents of the carcinogenic hazard biological factors present for a human being.

The relevance of the study results from high significance of nutrition and the growing interest of today’s researchers in the phenomenon of orthorexia nervosa (ON) as an obsessive desire for healthy, proper diet. The study aimed to assess ON severity in students. The students’ anthropometric measurements (body height, body weight), body mass index (Quetelet Index), ON severity based on the ORTO-15 questionnaire, features of the diet based on the Food Frequency Questionnaire were assessed, with subsequent statistical processing of the results. High prevalence of ON among both girls and young men (80.2% of the respondents) was shown. Furthermore, there were no differences in the ON phenomenon severity between young men and girls, and the relationship between the ON severity and the anthropometric measurements was non-significant (p > 0.05). Food selectivity associated with the phenomenon of ON was found in 3.3% of cases. Imbalanced diet was found in the majority of the respondents. The study has made it possible to conclude that the subjects constitute the group at risk of eating disorders. Further research is needed to accurately diagnose ON and reveal the relationship between ON and possible risk factors of this condition.

Great attention is traditionally paid to prevention of infectious diseases in pediatric population. Along with the institutional, therapeutic and preventive measures, it is necessary to control public awareness of such issues. The study was aimed to analyze awareness of primary school, high school, and senior school students, college and university students of the issues related to prevention of infections with fecal-oral and hematogenic transmission mechanisms. The study was carried out using the private online questionnaire consisting of three items (personal information, questions regarding awareness of the infections with fecal-oral and hematogenic transmission mechanisms). The properly filled questionnaires of the respondents, who had given to consent to participation in the study, were analyzed. It was found that schoolchildren aged 12–15 years were the least informed about the issues related to prevention of infections with fecal-oral and hematogenic transmission mechanisms, while the group of students aged 18–30 years was the most informed. It was hypothesized that parents influenced the choice of answer made by schoolchildren aged 6–11 during the online survey. It has been proposed to ensure raising of the 6–15-year-old students’ awareness of the issues related to prevention of infectious diseases, including by means of hygienic training when mastering such school curriculum subjects, as Biology and Human Life Safety.

Solving the problems of ensuring long and active life of all Russians, regardless of their place of residence, requires the development and implementation of digital preventive medicine technologies. It is noted that it is necessary to develop and implement health risk monitoring consistent with the digital technology development level, principle of data-driven management, and conceptual provisions of the disease prediction and prevention, personalized and participatory nature of medical care to create the human health shaping, maintenance, and preservation digital platform. The paper provides the rationale for the fact that the block (cascade) diagram of occupational health changes in aviation, the use of which as part of the digital platform to be created requires enlargement of the set of blocks of the health risk minimization cascade and the cascade of the risk factor effect minimization aimed to consider all the health risk minimization potentialities, as well as to develop methodological support of the risk factor dose and health risk calculation aimed to cover the maximum number of social and occupational population groups, meets these requirements.
