Abstract

Aim of the research is to compare the results of estimation of body mass components obtained by various methods, such as anthropometry, the bioimpedance analysis and DЕXA. DЕXA was used as a criterion method. Object – students of Russian Grammar School of Tartu (Estonia). In April of 2006, 64 children aged 8–11 years (27 boys and 37 girls) were investigated. Methods. Anthropometry (38 parameters were measured), the bioimpedance analysis and DEXA were carried out. Equations developed by L.B. Houtkooper et al., M.H. Slaughter et al. and J. Matiegka were used to calculate body mass components. An unpaired, two-tailed t-test was used to assess differences between the groups. Associations were analyzed with Spearman rank correlation coefficients. Multiple regression analysis was used to analyze the effect of different anthropometrical parameters to body mass components (DEXA). The results indicate similar trends between body mass components obtained by DEXA and different equations. Calculations according to the formulas of L.B. Houtkooper et al. and M.H. Slaughter et al. produce considerably low estimates of fat percentage than DEXA results, J. Matiegka equation gives higher percentage of fat content. The results based on the equations of L.B. Houtkooper et al. are markedly different from those obtained by criterion method both in boys, and in girls (in girls the differences are statistically significant). Equations of M.H. Slaughter et al. (especially in boys) and J. Matiegka give estimates approximating DEXA results.
