Abstract

The purpose of this article was to determine age-specific features of the morphofunctional and functional indicators of the physiological status in women permanently living in the European North of Russia. Materials and methods. The research involved 122 apparently healthy women (98 Komi and 24 Russian and Ukrainian) aged between 20 and 69 years (mean age 44.5 years) from Koslan Settlement, Komi Republic (63°6’N). In April 2023, the subjects’ morphofunctional, external respiration, blood circulation, and physical health parameters were studied using generally accepted methods. Different age groups by decades (20–29, 30–39, 40–49, 50–59 and 60–69 years) were compared and Pearson correlation analysis was performed. Results. In the first period of adulthood (20–29 years) most of the indicators have optimal values. In the following periods (30–59 years) many functions deteriorate. In older age (60 years and older) northern women show accelerated involution of most physiological functions (strength, static balance, hypoxemia tolerance, central hаemodynamic indices and integral indicators of performance and health). The analysis demonstrated that the correlations between age and the indicators under study expectedly reflect the fading of functions with age. The following parameters had weak correlations with age: body weight, body mass index, heart rate, pulse pressure, Kérdö index and index of functional changes. The comparison of the data obtained with other studies indicates that northern women, in relation to those living in middle latitudes, have an earlier onset of involution of physiological functions and premature agеing. Moreover, 28 years ago northern women in the rural areas of the Komi Republic were healthier than their peers today.
