[Age-associated dynamics in blood pressure and dispersion mapping of the electrocardiogram in comparison with the incidence of mortality from circulation system diseases in residents of Magadan.].

This research assessed blood pressure and dispersion mapping in reliance on age (Myocardium and Rhythm indices), the incidence of their deviations from the standard values in comparison with the tendency in mortality from diseases of the blood circulation system. For this purpose, we studied test results of 602 men and 776 women (total 1 378 people) aged 17-90 years who permanently inhabited Magadan city and underwent medical examination in 2016-2019, and mortality rates from circulatory system diseases during this period were estimated. The research showed a strong link of the increasing age to the growth in the blood pressure variables, with hypertensive focus, and the deviations in the ECG dispersion characteristics of the Myocardium and Rhythm indices tended to grow bigger.

[The effect of ω-3 polyunsaturated fatty acids on carbohydrate metabolism in northern men].

Omega-3 polyunsaturated fatty acids (PUFA) are known for being one of the most important classes of bioactive lipids; of them, the long-chain ones, namely eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids, have many positive effects on the human body. of this study was to assess the carbohydrate metabolism in northern men living in the Magadan Region before and after the administration of a dietary supplement with PUFA. .

[Main variables of carbohydrate metabolism in elderly men-northerners.].

Aging normally leads to profound changes in the homeostasis of carbohydrate metabolism, which is considered a good predictor of health state and life expectancy. The objective of this study was assessing main indicators of carbohydrate metabolism in Northern men of older ages living under conditions of the North-Eastern region of Russia (Magadan). The results of the study showed carbohydrate disorders in healthy elderly men who exhibited high values of fasting plasma glucose (5,81±0,20 mmol/L) and glycosylated hemoglobin (5,73±0,12%), mainly owing to elevated insulin resistance (HOMA-IR was 2,63±0,25 arb.

[Effect of short-term leave on functional characteristics of the body of northerners].

Unlabelled: Vacation is an essential feature of modern life for many people, and there is a fundamental assumption that short-term leave contributes to physical improvement and, thus, it is an improving the quality of life factor.

Objective: To study physiological and a number of psychophysiological body characteristics of the Magadan region residents when moving from northern latitudes to the conditions of the southern band in the summer period for vacation.

Material And Methods: Through year-round psychophysiological monitoring of a group, consisting of 19 male northern residents volunteers (mean age 33.

[Age-related dynamics of heart rate variability indicators in the population of Northerners young men, mature age and elderly men.].

Heart rate variability is a measure of autonomic nervous system that regulates cardiac function. It is also a potential tool for quantifying its physiological changes under the age aspect. The research examined age characteristics and differences in autonomic control of cardiovascular system based on heart rate variability indicators in individuals of different ages (young men, mature age men, and the elderly men).
