Abstract

SUMMARY. The article substantiates the expediency of using the phase angle (PA) index as one of the diagnostic criteria for sarcopenic obesity (SO) in young people. In recent years, there has been an increase in the prevalence of obesity not only among the elderly, but also among the younger generation. At the same time, early diagnosis of this condition cannot be considered a solved problem, since there are no clear diagnostic criteria for SO adequate for different age and gender categories of patients.

The aim – to find out the informativeness of the bioelectric phase angle in the differential diagnosis of sarcopenic obesity in young people.

Material and Methods. The study was conducted with the participation of 90 students of the School of Medicine of Uzhhorod National University aged 18 to 23 years on a voluntary basis in compliance with the principles of biomedical ethics. Among them, there were two groups of people with sarcopenic obesity and simple obesity and a control group, which included people with normal body mass index. Body composition and PA were measured using a bioelectrical impedance analyzer “TANITA MC-780 MA” (Japan). In order to confirm or exclude sarcopenia, each subject additionally performed a hand isometric test using a digital dynamometer Handexer Grip Strength Tester (USA).

Results. It has been established that the PA index demonstrates statistically significant differences between the study groups, both in the sample of women and men, and allows to distinguish individuals with sarcopenic obesity from individuals with simple obesity. At the same time, the generally accepted indicators - body mass index and percentage of body fat – are significantly different only in the control group.

Conclusions. PA can be used as a criterion for sarcopenic obesity in young people in the screening diagnosis of this condition. However, further studies involving a larger number of subjects are needed to determine the threshold values of this indicator for different age and sex categories of patients.
