Age-related anthropometric changes in physical development among aboriginal schoolchildren in Russia’s North-East
摘要
BACKGROUND: Schoolchildren from an educational institution of Severo-Evensk District Magadan Region, participated in an anthropometric survey.
AIM: To assess anthropometric characteristics of indigenous schoolchildren in the Magadan Region across different age-groups.
MATERIAL AND METHODS: Two hundred and eight boys and one hundred and ninety girls from the Evens, Koryaks and Itelmen ethnic groups participated in the 2021–2023 Anthropometric Survey. They accounted for 67.2% of all schoolchildren surveyed. Body height (BH), body mass (BM), chest circumference (CC), sitting height (HSit), right- and left-hand grip strength were measured. We also calculated annual increase in weight and height, as well as proportionality of physical development of the children.
RESULTS: A natural increase in the absolute body indicators of BH, BM, HSit, CC, and right and left hand strength have been observed parallel to increase in age from 8 to 17 years. The rate of annual growth indicated different timing of the periods of accelerated increase in the anthropometric characteristics. Girls exhibited a CC maximum increase at 10–11 years old with simultaneous increase in BH, BM, HSit, and hand grip strength at 11–12 years old. During the same age-periods, boys showed a pronounced BH growth with BM and CC increase at 12–13 years of age. After a slight attenuation in the growth rate, we observed a substantial increase in BH at the age of 14–15, associated with gender-related aspects in older children groups. Sex-related characteristics of BH increase were primarily associated with differences in the leg growth rates during the puberty, and tend to be greater in boys. Most of the studied boys had an asthenic somatotype. At the same time, most girls had a proportional body type with high percentage of those with relatively short legs.
CONCLUSION: We observed that girls were ahead of boys in their physical development. Boys demonstrated a continuous development in their main anthropometric characteristics with more pronounced dynamics in adolescence. Our findings suggest that indigenous schoolgirls have better physical development and adaptive adjustments compared to boys.

Analysis of the correlations between ECG components in adolescents both before and after exposure to different types of physical stress in the Subarctic winter conditions
摘要
BACKGROUND: Adaptive responses to harsh environmental conditions of the Arctic may vary not only among adults, but also among children and adolescents. These compensatory reactions are influenced by the predominant type of regulation of the autonomic nervous system. The myocardium and its electrical properties play a significant role in determining how individuals adapt to to environmental conditions.
AIM: To study correlations between PP and TR intervals in adolescents in adolescents undergoing the clinostatic test and the Martinet test during the winter season.
MATERIAL AND METHODS: Twenty cardiac cycles were recorded in 22 adolescents aged 15–16 years in the II standard lead, both at baseline and after conducting the clinostatic and Martinet tests. Durations of the RR and TR intervals were measured and used for the analysis. Statistical processing of the data was performed using the MS Excel tables.
RESULTS: Based on both individual and group data analysis, it has been observed that the duration of RR and TR increases during the clinostatic test, while it decreases during the Martinet test. The extent of these changes in RR and TR varies between the two tests. Specifically, the RR:TR ratios are 1:3.5 during the clinostatic test and 1:2.5 during the Martinet test. These findings suggest a higher likelihood of parasympathetic influences on the electrical properties of the myocardium during the clinostatic test, and sympathetic influences during the Martinet test.
CONCLUSION: Duration of RR and TR intervals increased by 25% and 85%, respectively, in response to the clinostatic test. Conversely, after the Martinet test, the duration of both intervals decreased by 15% and 38%, respectively. These findings suggest that the changes in the duration of RR and TR intervals are influenced by the parasympathetic and sympathetic divisions of the autonomic nervous system, under different types of physical stress. Further research should be conducted in other seasons, particularly during transitional periods such as spring and autumn, to better understand the electrical properties of the myocardium under physical stress.

Maternal correlates of spontaneous preterm birth in Kazakhstan: a matched case-control study
摘要
BACKGROUND: Preterm birth (PTB) continues to be a persistent health issue that significantly impacts neonatal morbidity and mortality worldwide. In Kazakhstan, the prevalence of PTB is 7% making a substantial contribution to adverse health outcomes among infants. However, there is a lack of comprehensive research on the factors contributing to PTB in Kazakhstan.
AIM: To study maternal factors associated with spontaneous PTB among Kazakh women.
MATERIAL AND METHODS: A case control study was conducted in three major reproductive hospitals in Atyrau, Aktobe and Kyzylorda from October 2022 to January 2023. The sample consisted of 90 cases with singleton live spontaneous PTB and 180 controls with spontaneous full-term delivery. Bivariate associations between categorical variables were assessed by chi-squared tests. Independent variables with p <0.1 in the bivariate analysis were entered into a conditional logistic regression model. Odds ratios (OR) with 95% confidence intervals (CI) were calculated.
RESULTS: Maternal education, periodontitis, body mass index and a history of PTB in previous pregnancies were associated with PTB in bivariate analysis. In multivariable models, only prior PTB (OR=38.10; 95% CI: 8.34–142.00) and periodontal disease (OR=2.09; 95% CI: 1.15–3.80) were associated with an increased risk of extremely and very preterm births while higher education (OR=0.44; 95% CI: 0.19–0.98) and a history of PTB (OR=27.20; 95% CI: 5.38–137.00) were associated with moderate to late PTB.
CONCLUSION: Our results are in line with the international evidence on prior PTB being the most important determinant of PTB in the index pregnancy. Moreover, our findings on the associations with periodontal disease underline the importance of a targeted, individualized and interdisciplinary antenatal care to the reduction in the prevalence of PTB.

Students' perceptions of well-being
摘要
BACKGROUND: In today's society, there is a need to explore strategies for attaining and improving overall well-being. This exploration requires an examination of perceptions of well-being in different social groups. First and second-year students in higher education institutions represent the future social capital of the nation. Understanding the factors that contribute to their sense of well-being is essential, as it can determine their future social interactions and behaviors.
AIM: to identify the content of students’ perceptions of well-being.
MATERIAL AND METHODS: The study included 258 first- and second-year university students. The main research method was a modified free association technique, where students were asked to provide three associations in the form of verbs, adjectives, and nouns, resulting in a total of nine associations per participant. Data were analyzed using frequency analysis and calculation of ranks.
RESULTS: A total of 2322 associations were identified among students. These associations were then organized to form 51 associative groups, which were further combined into 16 semantic groups for meaningful interpretation. The concept of "well-being" was analyzed within a structured semantic space, focusing on emotional and motivational-need characteristics. The semantic space of the concept of “well-being” is structured according to emotional and motivational-need characteristics. The emotional component of well-being encompasses a range of positive emotions with varying degrees of intensity. On the other hand, the motivational-need component primarily addressed needs related to physical comfort, safety, basic life support, and material support.
CONCLUSION: In the content of university students’ perceptions about well-being, the emotional sphere holds the most significant position. Students associate well-being with feelings of calm joy, happiness and emotional stability. Additionally, perceptions of well-being are centered around fulfilling basic and material needs.

Effects of seasonal temperature fluctuations and social factors on the transmission of malaria
摘要
AIM: To conduct a retrospective analysis of the incidence of malaria episodes in the Astrakhan region from 2002 to 2022 in relation to climatic and social factors in order to provide the evidence for development of effective preventive measures.
MATERIAL AND METHODS: An observational study. We performed correlation analysis to study associations between the spread of malaria and climatic and social factors in 2002–2022 in the Astrakhan region. The analysis was based on the data obtained from reporting forms of the Center for Hygiene and Epidemiology in the Astrakhan Region and Rospotrebnadzor in the Astrakhan region. Statistical processing of the data was carried out using Microsoft Office Excel tables (Microsoft, USA) and BioStat Professional 5.8.4.
RESULTS: A decrease in the number of malaria cases in the Astrakhan region over the study period was a positive trend, which indicates the importance and effectiveness of measures to combat this serious disease.
CONCLUSIONS: It is necessary to continue working in this direction in order to ensure the safety and well-being of the population in relation to the reported imported cases of malaria in the region.

Effects of training load on heart rate variability and blood pressure in track and field athletes and skiers
摘要
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.
