Introduction. The modifications in physiological indices produced among population with overweight and obesity constitute an objective basis that allows to study the action of different factors on the human organism.

Research question(s):

Assessment of the peculiarities of body composition among subjects with body mass index ≥25 kg / m².


The study included: group I - 243 persons with hereditary family history of excess of body mass and group II - 180 persons without hereditary family history of excess of body mass.


The results of the study show that the percentage of water (group I - 51.7 ± 3.7%, group II - 52.1 ± 3.2%), of skeletal muscles (group I - 30.9 ± 1.9% , group II - 31.1 ± 2%) and bones mass (group I - 2.4 ± 0.6 kg, group II - 2.5 ± 0.6 kg) decrease in the same time with increasing of body mass index values.


The decrease of the percentage of water can retard the metabolism as ingested water stimulates the increase of energy consumption in the body. In result, the body weight is maintained within the normal body mass index. At the same time, insufficient physical activity can reduce the percentage of skeletal muscles as well as the bones weight, which can influence the appearance of bones fragility and fractures among subjects with overweight and obesity.

Points for discussion:

Along with the increase in the incidence of obesity, the body composition also changes

Obesity is a major risk factor in many chronic non-communicable diseases

Obesity poses a risk of fractures
