- Abstract
In the present study, hand-to-hand bioelectrical impedance analysis (BIA), skinfold (SKF) thickness and height–weight (body mass index, BMI)-based equations and dual-energy X-ray absorptiometry (DEXA), as a criterion method, were compared with each other in the assessment of body fat percentage (BF%) in 17–18-year-old Estonian conscripts ( n = 32). The Omron®BF body fat monitor estimated that BF% was lower than that of the criterion method DEXA. The difference between DEXA and Omron®BF 300 (III) was higher (1·1 ± 3·0%; P = 0·04) and that between DEXA and Omron®BF 306 lower (0·2 ± 3·0%; P>0·05). Omron®BF 300 (I) and (II) (series 8) had intermediate difference (0·9 ± 3·0 and 0·9 ± 3·0; P>0·05) when compared with DEXA. Three anthropometric equations estimated a higher BF% than cthat of DEXA. The Durnin & Womersley SKF equation BF% (1·0 ± 2·4; P = 0·03) was higher than that of the DEXA. Deurenberg et al. and Gallagher et al. BMI-based equations overestimation yielded 0·9 ± 3·7 and 0·6 ± 3·8 BF% ( P>0·05). From the anthropometric equations, only the Deurenberg et al. SKF equation slightly underestimated 0·5 ± 3·4 BF% ( P>0·05). DEXA-assessed BF% had highest correlation with SKF equations ( r = 0·93), less so with BIA ( r = 0·88–0·89) and lowest with BMI equation-assessed BF% ( r = 0·81–0·84). All values were significant at P<0·001. We can conclude that the Omron®BF 306 body fat monitor and the anthropometric Deurenberg et al. SKF equation yielded results close to the DEXA BF%.
