Although the waist-to-hip ratio (WHR) has emerged as the best anthropometric indicator of the body's adipose tissue distribution, it has never been directly validated. Waist and hip girths, and triceps and subscapular skinfold thickness were measured in 12 male and 13 female cadavers aged 55-94 y. Adipose tissue from the upper limbs, lower limbs, subcutaneous trunk and intra-abdominal regions was then separated by dissection and weighed. Adipose volumes were also determined by hydrostatic weighing. The following adipose tissue mass ratios (and corresponding volume ratios) were derived: trunk to sum of lower limbs, trunk to sum of upper and lower limbs, intra-abdominal to sum of lower limbs and intra-abdominal to sum of upper and lower limbs. Centrality index (CI-subscapular-to-triceps skinfold ratio) and WHR were regressed on the tissue mass and volume ratios of the 25 cadavers. WHR was significantly related to mass and volume ratios for the 12 men (R2=36.0-57.5%, P<0.05), except for intra-abdominal to sum of upper and lower limbs (R(2)=26.3%, P=0.09), but none of these relations was significant in the women. CI was significantly related to all mass and volume ratios only for men and women combined (R(2)=16.2-21.8%, P<0.05). The WHR was better related to all mass and volume ratios than the CI. These results, especially the strong association between WHR and the ratio of intra-abdominal to lower limb adipose masses (R(2)=35.4%, P=0.002), demonstrate a clear relation between the selected anthropometric variables (hip and waist girths, and subscapular and triceps skinfolds) and adipose tissue distribution, thus validating the use of WHR as an important predictor of health risk.
尽管腰臀比（WHR）已成为身体脂肪组织分布的最佳人体测量指标，但它从未得到过直接验证。对12名年龄在55 - 94岁的男性和13名年龄在55 - 94岁的女性尸体测量了腰围、臀围、肱三头肌和肩胛下皮褶厚度。然后通过解剖分离并称重上肢、下肢、躯干皮下和腹腔内区域的脂肪组织。还通过静水称重法测定了脂肪体积。得出了以下脂肪组织质量比（以及相应的体积比）：躯干与下肢总和之比、躯干与上下肢总和之比、腹腔内与下肢总和之比以及腹腔内与上下肢总和之比。将中心性指数（CI - 肩胛下与肱三头肌皮褶厚度之比）和WHR对25具尸体的组织质量和体积比进行回归分析。WHR与12名男性的质量和体积比显著相关（R2 = 36.0 - 57.5%，P < 0.05），腹腔内与上下肢总和之比除外（R(2)=26.3%，P = 0.09），但在女性中这些关系均不显著。仅在男性和女性合并分析时，CI与所有质量和体积比显著相关（R(2)=16.2 - 21.8%，P < 0.05）。WHR与所有质量和体积比的相关性优于CI。这些结果，尤其是WHR与腹腔内与下肢脂肪质量比之间的强关联（R(2)=35.4%，P = 0.002），表明所选人体测量变量（臀围和腰围，以及肩胛下和肱三头肌皮褶厚度）与脂肪组织分布之间存在明确关系，从而验证了将WHR用作健康风险重要预测指标的合理性。
