In this paper we present the results of the parameters of body composition in children on early school age. The sample consisted of 60 probands (40 boys and 20 girls) with a mean age by the decimal 6.73 ± 0.3 years. To determine body composition parameters were used for direct analysis of segmental multi-frequency bioelectrical impedance using the InBody 120 (Biospace Co., Ltd .; Seoul, Korea). All the results of measurements, we mutually compared and evaluated using statistical methods. The parameters of body composition was recorded intersex differences, but not statistically significant. Statistical differences were observed in the total body water (TBW) and the level of the basal metabolic rate (BMR). The parameters showing the state of nutrition, protein mass (PM) and the mineral mass (MM), we also confirmed the statistically significant differences intersexual. Somatic indicators of significant statistical dependence is found between body height and weight, as well as between body weight and body mass index, which will be shown ontogeny is assessed as a natural developmental indicator. The same statistically significant dependence was recorded also in the analysis parameters obesity parameters of active body mass and nutritional parameters.
