A high risk of physical inactivity is emerging among students in the context of the high level of informatization in public life, the widespread development of online delivery services, and the growing popularity of network forms of interpersonal communication. The cross-sectional descriptive study aimed to identify the features of the medical students’ physical activity and the risk factors influencing the development of physical inactivity during the period of study. We conducted an anonymous online questionnaire survey of 431 students of the Pavlov Ryazan State Medical University on the forms.yandex.ru platform using questions from the Physical Activity Level Self-Assessment Form adapted by А.V. Kabachkova (2025). The majority of students (61.95%), who took part in the study, had low physical activity. The higher prevalence of moderate, sufficient, and high physical activity was reported in male respondents compared to female ones (χ2 = 20.36; р < 0.001). There is a downward trend of the medical students’ physical activity from the first to the third year, a significant increase in physical activity in the fourth year and a subsequent decline by the sixth year. The decrease in the proportion of students with low physical activity and the increase in the proportion of students with moderate and sufficient physical activity with decreasing time spent on electronic devices are observed (χ2 = 34.5; р < 0.001). Risk factors for low physical activity among medical students include studying in the third or sixth year of medical university, female gender, and significant time spent using electronic devices.

To identify the most relevant directions for research in the domain of hygienic education, it is necessary to summarize and systematize the accumulated research materials and practical guidelines. This study analyzed existing scientific and practical evidence on hygienic education in various populations. The Russian Science Citation Index (RSCI) enabled analysis of the publication trends in the field of hygienic education. We considered works published from 1995 (when the first paper was added to the index) to the third quarter of 2025 inclusive. The pool included 663 publications, mostly by Russian authors. The total number of citations is 2402. The number of publications with zero citations is 278. The average number of citations per publication is 3.62 ± 1.22. The analysis of the publication activity in the domain of hygienic education has shown that this problem is underexplored, and there is an insufficient number of fundamental guidelines and original research on topical issues, as well as dissertations covering this subject matter. There is a need for sustained dialogue between researchers and practitioners in this field in leading hygiene journals, to share scientific experience, enhance cross‑citation of research, extend the use of these materials to other regions, and drive the development of new technologies for hygiene education.

Recently, there has been an increase in the number of cases of unsafe use of medications, including antipsychotics, by the population. The uncontrolled use of medication leads to an increase in the rate of physical health problems and a decrease in the quality of life. Predicting the effects of substances in the body and identifying such cases are tasks of preventive medicine. The study aimed to assess the possibility to use the antipsychotics. Male outbred rats intragastrically administered 35 mg/kg and 10 mg/kg, respectively, were used for the experiment. The control group was administered distilled water. Structures of blood serum facies were assessed 1, 4, 24 h after the antipsychotic administration. Parametric statistical methods were used for the analysis of comparative data (р £ 0.05). Similarities of the structures of rat and human blood serum under physiological conditions were identified. The emergence of structures deviating from normal was observed in the rat facies after the and After 1 h, "silver" cracks were detected; after 4 h, rope-like structures resembling a "leaf-within-a-leaf" (following haloperidol administration) and a "double leaf" (following aminazine administration) were observed; and after 24 h, an increase in the thickness of triradiate cracks was noted. The findings demonstrated the efficacy of the wedge-shaped dehydration method in the experimental assessment of the effects of antipsychotics.

The high prevalence of nutrition-related disorders among children necessitates the development of new methods for assessing the effects of nutrition on the body. Heart rate variability (HRV) analysis combined with the body mass index (BMI) calculation constitute an effective non-invasive health status assessment protocol. This cross-sectional study aimed to evaluate the dietary patterns of schoolchildren in Yekaterinburg and examine their associations with BMI and indicators of autonomic nervous system function. We recruited 202 schoolchildren aged 11−12 years; their diets were assessed using the frequency method and by calculating the nutrition quality index (NQI). We collected the participants' anthropometric data, measured their bioimpedance, and analyzed the HRV. Nonparametric methods, odds ratio calculation (ORC) and cluster analysis were used for statistical processing. It was found that the quality of the diets of 67.3% of schoolchildren was unsatisfactory: their diets were excessive in saturated fats, added sugars, and sodium, and deficient in dietary fiber, complete proteins, B vitamins, vitamin A, calcium, and magnesium. Children with a low NQI are 5.5 times more likely to be overweight and have a higher body-fat percentage than their peers with a satisfactory diet. HRV indicators differed significantly according to dietary patterns: children who consumed large amounts of vegetables and fruit exhibited more favorable heart rate variability, whereas those whose diets were high in added sugars and fats had the least favorable HRV. The identified abnormalities highlight the need to develop preventive programs aimed at improving eating habits and to consider introducing HRV monitoring into the schoolchildren's health hygienic assessment system.

The problem of inadequate nutrition among students is especially significant at medical universities, where the academic workload is high. It is particularly important because the years spent in higher education are when long-term eating habits are formed, and the body undergoes its final stages of development. In this work, we aimed to assess how the intensity of the educational process affects daily diet and eating behavior of students, and suggest substantiated preventive measures. The cross-sectional study involved 199 second-year students (114 women and 85 men; mean age 19.5 ± 1.5 years), who completed a questionnaire; the results were then processed using descriptive statistical methods. We assessed the caloric and macronutrient composition of the diet, dietary regime, and behavioral factors. The mean dietary energy intake was 1597.3 ± 27.1 kcal; the diet was calorie‑deficient for 122 participants (61.3%) and adequate for 59 (29.6%) (p < 0.001). By nutrient, 122 participants (61.3%) did not consume enough protein, 117 (58.8%) lacked sufficient fat, and 100 (50.3%) had insufficient carbohydrate intake. Young men consumed more energy than young women (1701.6 ± 31.8 vs. 1520.4 ± 25.3 kcal; p < 0.001). Only 44.4% of the respondents ate three meals a day, while 24.2% ate two or less. Regular consumption of fast food products was admitted by 157 students (78.9%). The resulting data indicate systemic nutritional deficiencies and the need to implement preventive measures in educational settings.

One way to meet the body's physiological nutrient needs is to normalize the population's diet through specialized food products (SFP), including biologically active supplements (BAS). At the same time, the content of bioactive substances in these products requires confirmation of compliance with the mandatory requirements of the Eurasian Economic Union (EAEU) legislation. Sanitary and epidemiological examination is key to obtaining a positive or negative decision on the SFP's compliance with established requirements and declared properties. ased on the results of the sanitary and epidemiological examination, Rospotrebnadzor or another authorized body decides to issue a state registration certificate (SRC), which serves as a document allowing the manufacturer to produce and sell SFPs within the EAEU. This article presents an assessment of modern hygienic approaches to the sanitary and epidemiological examination of SFPs and provides explanations of the procedure for preparing the required documentation for examination. The provisions of the publication will be useful to specialists performing sanitary and epidemiological examination of SFPs, as well as to manufacturers and applicants planning to obtain a SRC.
