Far North residents’ age-related peculiarities based on construction of functional state matrices

Abstract

Background: Living in Russias Far North brings pronounced natural and social characteristics that exert an unfavourable influence on the human functional state. Objective: This study analyzed assessment of medical, physiological, and social factors determining the body functional state in northerners of different age groups. Methods: The research involved male residents of Magadan region, Caucasians by origin: one hundred and fifty-six young men aged 17-21 (mean age 18.5 0.6 yr), fifty-six men of the working age of 34-45 (mean age 37.4 0.5 yr) and forty-five elderly men at the age of 60-77 (mean age 65.9 1.1 yr). The participants somatometric variables were measured. The functioning of cardiovascular and respiratory systems, insulin resistance, as well as the pictures of blood biochemistry, vitamin D, trace element and basal metabolism were assessed. The subjective tobacco smoking and motor activity rates were also analyzed. Results: We can conclude that the body systemic functioning is increasingly stressed out with age. We determined that subjects, as they age, exhibit increased incidence of those with arterial hypertension, insulin resistance, and elevated blood glucose and atherogenicity coefficient levels. We also identified elevated bronchial obstruction index and lowered variables of respiratory functioning in older people who reported consistently high levels of tobacco consumption. Conclusion: The developed matrices illustrate the worsening observed in subjective functional reserves and increasing intensity occurred in body systems of examinees as they grow from ontogenesis of the youth to the elderly.
