Features of biometric parameters of men elderly and senile age

Background. Studying the variability of anthropo- and bioimpedance parameters of elderly and senile men makes it possible to carry out timely preventive measures, reveal diseases in the early stages and apply personalized therapeutic measures. Material and methods. The biometric characteristics of elderly (61–75 years, group I – n = 68) and senile (76–90 years, group II – n = 61) men were studied using anonymized (with known gender and age) dates of anthropo- and bioimpedance-metric parameters with phase angle values within age norms from the archives of the Center for Prevention and Health of Engels, Saratov Region. Total dimensions, component composition of the body, and impedance indicators were determined. Results. In senile men, relative to the elderly, there is a statistically significant decrease in length, body weight, hip girth, fat, lean, active cell mass, total fluid, ecto- and mesomorphy indicators (p < 0.05); Waist circumference and endomorphy index also decrease, but the differences do not reach statistical significance (p > 0.05). Active and reactance increases (p < 0.05), and the increase in specific basal metabolism does not reach statistical significance (p > 0.05). Variability of varying degrees in the studied parameters was revealed. Conclusion. Most of the studied parameters (total dimensions, body fractions) in old age relative to older men decrease; impedance indicators such as active and reactance in relation to body length and specific basal metabolism (basic metabolism in relation to body surface area) increase. The closeness (strength) and direction of the connections, as well as the degree of variability of the parameters, were revealed.
