ABSTRACT

The purpose of this study was to validate an alternative skinfold equation for women created from dual-energy x-ray absorptiometry (DXA). Anthropometrics and a whole-body DXA scan were completed on 77 women (mean age: 28.0 ± 10.2 years). Four Jackson-Pollack (JP) skinfold prediction equations and the DXA criterion (DC) equation were compared to DXA-derived body fat percentage (%BF). One-way repeated measures ANOVA revealed significant differences (p ≤ .001) in the %BF with post hoc-comparisons revealing significant differences among JP7 (21.3 ± 5.7), JP4 (21.4 ± 5.7), JP3a (22.2 ± 5.9), and JP3b (22.6 ± 5.7) when compared to the DXA-derived %BF; no significant difference existed between DC %BF (26.5 ± 5.6) and DXA-derived %BF (26.5 ± 5.4) (p = 1.0). The DC equation more accurately predicted %BF in women volunteers compared to Jackson-Pollack equations.

基于双能X射线吸收法估算女性体内脂肪百分比的皮褶预测方程的验证

摘要

这项研究的目的是验证由双能X射线吸收法(DXA)创建的女性的替代皮褶方程。对77名女性(平均年龄:28.0±10.2岁)进行了人体测量学和全身DXA扫描。将四个Jackson-Pollack(JP)皮褶预测方程式和DXA标准(DC)方程与DXA衍生的体脂百分比(%BF)进行了比较。单向重复测量ANOVA表明显著差异(p与事后-比较JP7(21.3±5.7),JP4(21.4±5.7),JP3a(22.2±5.9)间的露出显著差异%BF≤0.001),和与DXA衍生的%BF相比,JP3b(22.6±5.7);DC%BF(26.5±5.6)与DXA衍生的%BF(26.5±5.4)之间没有显着差异(p= 1.0)。与Jackson-Pollack方程相比,DC方程可以更准确地预测女性志愿者的%BF。
