Objective: To study the peculiarities of the composition in patients over 50 years old.Materials and Methods: The study involved 136 adults aged 50 to 82 years. All subjects underwent complex examination, which included anthropometry (height, weight, body mass index (BMI)) and body composition analysis using Inbody 770 (Inbody Co.Ltd., Korea). Statistical processing of the results was performed using MedCalc Statistic software.

Results: women’s age was 60[55.0;64.0] years, weight 74.5 [66.3;85.2] kg, height 159[156.0;164.0] cm, BMI 29.4 [25.0;33.8] kg/m². Body fat mass was 31.4[21.8;39.9] kg, body fat percentage 42.4 [37.2;48.0]%, visceral fat area 164.2 [127.7;201.5] cm², skeletal muscle mass 23.6[21.3;26.0] kg, appendicular muscle mass 6.48 [5.9;7.3] kg according to bioimpedanceometry. Appendicular muscle mass deficiency was found in 15.0% of the women’s group. In the group of women with a normal BMI, 78.8% had changes in body composition according to bioimpedance measurements (increased body fat mass, percent body fat mass); 42.1% had visceral obesity; appendicular muscle mass deficiency was found in 52.6%. Male age was 58.5 [50.0;65.0] years, weight 92.4 [77.2;106.9] kg, height 173.5 [168.0;180.0] cm, BMI 30.9 [25.8;34.7] kg/m². Body fat mass was 26.5 [16.3;40.3] kg, body fat percentage 31.8 [21.8;39.5]%, visceral fat area 128.8 [83.6;189.0] cm², skeletal muscle mass 34.6 [29.9;40.5] kg, appendicular muscle mass 8.8 [7.9;9.2] kg according to bioimpedance measurement. The prevalence of reduced appendicular muscle mass in men was 12.5%. In the group of men with a normal BMI, 71.4% had changes in body composition by bioimpedance analysis (increased body fat mass, percent body fat mass); 42.1% had visceral obesity.

Conclusions: in some cases BMI did not reflect the actual degree of fat deposition and did not allow for differentiation between fat and muscle mass. The observed changes in body composition among those examined with a normal BMI indicate the need for more active diagnostic tactics and the use of additional tools for early detection and correction of these abnormalities, due to their association with reduced life expectancy and quality of life, as well as the risk of developing a number of metabolic disorders.
