The use of the DEXA method as a criterion to validate results of measurements of body fat segmental distribution while using a tetrapolar bioelectrical analysis.

The sample team included 89 individuals (53 males and 36 females). Their average age was 19.7 in case of men, and 19.5 in case of women. These were adolescent individuals without any health issues who were not taking any medication or dietary supplements. Measured parameters included their body height, total body weight, total body fat and body fat in individual segments of the body. The measurement using bioelectric impedance was conducted by the tetrapolar bioimpedance scale Tanita BC 418 MA. To assess the validity we used the modelling of the relationship between the observed variables through various models of regression functions. To assess the empirical validity, the Pearson correlation coefficient (r), standard error of the estimate (Sy/x = SEE) and the marginal error of criterion estimate (dmax) were used.

When comparing the average values of representation of body fat in individual segments, statistically significant differences were found for all parameters. This also confirmed practical significance as Cohen’s d ranged from 0.5 to 1.5. The values of the Pearson correlation coefficient (r), expressing the degree of validity against the DEXA method, ranged from 0.50 to 0.86. The dmax (±2 Sy/x) values ranged from 0.22 to 0.88 kg and 3.30 to 9.30% of fat.

Based on the results of the segmental analysis of body fat distribution by the Tanita BC 418 MA analyser, we cannot precisely estimate values acquired by the DEXA method. The results are impacted by the high value of dmax. The empirical validity of the segmental analysis of body fat distribution is still significantly lower than in case of the whole body analysis.

Key words:
statistical significance, practical significance, dual roentgen absorptiometry, standard error of the estimate, adolescent population K.
