New aspects in the assessment of biological age

Abstract

Introduction. Biological age is an integral indicator of the individual human health level that characterizes the functional, regulatory and adaptation features of man. However, two people of the same age range differ greatly from the biological age due to the degradation of several physiological functions. The issue of biological age is the key to studying the influence on changes in the body at all stages of individual development from birth to death, united by the term ontogenesis. Biological age provides an estimate of individual age status. Materials and methods. Among people of the same chronological age, there are usually great differences in the age-changing tempo. The difference between chronological and biological age, which allows the appreciation of an individual's aging intensity, is very high in various stages of the aging process. The highest speeds in age changes are seen in longevity people, younger ones are insignificant. Therefore, to determine biological age makes sense only to people older than 30 years or even 35 years. In auxology, different systems of biological age appreciation which correspond to the listed requirements, are applied. So called skeletal age, dental age, sexual development, morphological development, physiological, and mental maturity, and others. Results. An increase in aging rate in younger and middle-aged individuals was observed compared to older people, which corresponds to the modern demographic trend of rejuvenating mortality from several causes. Taking into account the lack of significant difference in age in male and female subjects of different age groups, we were given the opportunity to evaluate gender differences in dynamic age of the biological age. It accelerates the rapid aging of men at young age, especially when reaching average age. Conclusions. Chronological and biological age of people observed lodged between on the study conducted it was found an increase in speed of aging in people of young and average age in comparison with people, which corresponds to the demographic trend of modern rejuvenation of mortality.
