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.
