Anthropometry in blacks: applicability of generalized skinfold equations and differences in fat patterning between blacks and whites

Abstract

To test the accuracy of generalized skinfold (SF) equations in blacks and to compare fat patterning in black and white adults, percent body fat (%BF) was assessed in 90 blacks and 89 whites by deuterium oxide dilution (D2O) and by generalized SF equations [Durnin and Womersely (DW), and Jackson and Pollock and Jackson et al (JP)] by using two calipers (Lange and Holtain). In blacks, JP significantly underpredicted (2.95%) and DW overpredicted (1.74%) D2O %BF with the Lange caliper. With the Holtain caliper DW successfully predicted D2O %BF (r = 0.91, SEE = 3.8%). In whites, DW overpredicted D2O %BF more than in blacks (4.94% vs 1.74%). Lower triceps-subscapular and thigh-subscapular skinfold-thickness ratios in black females and lower suprailiac-subscapular ratios in black males and females were found. It was concluded that blacks may have more visceral and upper-body fat deposition.
