Effect of Daily Rhythms of Cortisol Secretion on the Rate of Aging in Men

Abstract

The phenomenon of human aging is the result of a complex interaction among several factors in which the immune system plays a key role. Cortisol is a glucocorticoid secreted by the adrenal gland and has a specific secretion pattern. The current study aimed at identifying the cause and pathogenesis of premature aging using biological markers. This study was performed based on the results of clinical and instrumental examinations on 91 middle-aged men aged 45-59 years. VaseraVS-1500 sphygmomanometer based on standard methods was used to measure biological age. The relationship between biological age and circadian rhythms of cortisol secretion was calculated to elucidate the pathophysiological mechanisms of aging development. The recorded data showed that the violation of the circadian rhythms of cortisol secretion characterized by a consistently high level of the hormone throughout the day was typical among individuals with accelerated types of aging. Based on the obtained data, a formula for determining the biological age of the studied groups of patients was prepared by considering the circadian rhythm of cortisol secretion, which can be an additional tool for early detection of aging in men.
