Introduction. Proper assessment of the proper and actual adiposity of each individual person is an important socio-economic task of modern medicine [3]. According to the classification [1], all people are divided into asthenics (AS), normosthenics (NS), and hypersthenics (HS) depending on the ratio of longitudinal and transverse skeletal dimensions [1, 3]. A more detailed analysis of body types [3] made it possible to identify normally, excessively, and insufficiently adipose AS, NS, and HS.

Abstract

Objective of the study is to study morphometric indices in persons aged thirty, to identify variants of combinations of adiposity and body type, and their gender differences.

Methodology and organization of the study. A morphometric examination was conducted on 390 persons (165 men and 225 women aged 30 years); the body type index (BTI) and adiposity index (AI) were studied. Using BTI and AI, all body types (asthenics, normosthenics, and hypersthenics) can be divided into normally, excessively, or insufficiently adipose variants using new somatic indicators: body type index and adiposity index (based on measurements of height, body weight, and wrist circumference) [3]. Accumulation, correction, and systematization of initial information were carried out in Microsoft Excel 2016 spreadsheets. Statistical analysis was performed using Statistica 10.0 software.

Results of the study and their discussion. Statistical analysis showed that for thirty-year-old men, the following ratios of the main body types are characteristic: normosthenics – 52.1%, asthenics – 22.4%, hypersthenics – 25.5%. For women, the ratios of the main body types were close in value: NS – 53.3%, AS – 24.4%, HS – 22.2%. In the group of men, normal adiposity occurred in 53.2%, insufficient adiposity – 24.9%, excessive adiposity – 21.9%. In the group of women, normally adipose were 64.6%, insufficiently adipose – 17.6%, excessively adipose – 17.8%. Significant differences were found in the following variants of combination of adiposity and body type: in women, compared to men, there are fewer excessively adipose normosthenics (4.0±0.92% vs. 10.9±1.5%) and normally adipose hypersthenics (2.2±0.69% vs. 6.1±1.13%).

Conclusion. The theoretical and methodological basis for the division was provided by new somatic indicators: body type index (BTI) and adiposity index (AI). The relative novelty of the work was their use for studying a group of thirty-year-old persons living in the conditions of Southern Russia. Gender differences in body build in the group of normally adipose normosthenics are easily identifiable and highly significant.
