脊髓损伤（SCI）是一种显着改变身体成分的独特病症，增加了对身体成分的传统假设产生不确定影响的可能性。为了确定分析该人群身体成分的适当方法，通过以下方法研究了 12 名四肢瘫痪受试者的绝对体重（脂肪）和脂肪百分比；生物电阻抗 (BIA)、双能 X 射线吸收测定法 (DEXA)、全身钾 (TBK)、全身水分 (TBW) 以及四种人体测量方法：Durnin 和 Womersley (DUR)、Jackson 和 Pollack (J 和 P)、Sloan (SLN) 和 Steinkamp 等人 (STK)。将八种方法与所有平均值（24.4 +/- 2.2% 脂肪）进行比较，这被认为是脂肪百分比的最佳估计。四种方法：BIA、DEXA、TBW 和 STK 没有显着差异，而 TBK、DUR、J&P 和 SLN 与均值显着差异（P < 0.009）。仅使用非显着不同的方法，重复计算显示 TBW 与平均值的差异最小 (0.1 +/- 2.8%)，DEXA 与同一线具有最强的相关性 (r = 0.96，P < 0.0001)。总之，BIA、DEXA、TBW 和 STK 对于估计四肢瘫痪患者的脂肪同样有价值。
Spinal cord injury (SCI) is a unique condition that markedly alters body composition, raising the possibility of having undefined effects on the traditional assumptions for body composition. In order to determine appropriate methods for the analysis of body composition in this population, 12 subjects with tetraplegia were studied for absolute weight as fat and percent fat by the following methods; bioelectrical impedance (BIA), dual energy X-ray absorptiometry (DEXA), total body potassium (TBK), total body water (TBW), and four anthropometric methods: Durnin and Womersley (DUR), Jackson and Pollack (J and P), Sloan (SLN) and Steinkamp et al (STK). The eight methods were compared with the mean of all means (24.4 +/- 2.2% fat), which was assumed to be the best estimate of percent fat. Four methods: BIA, DEXA, TBW and STK were not significantly different, while TBK, DUR, J&P and SLN were significantly (P < 0.009) different from the mean of the means. Using only the non-significantly different methods, repeat computation revealed TBW to have the smallest difference from the mean (0.1 +/- 2.8%), and DEXA to have the strongest correlation with the line of identity (r = 0.96, P < 0.0001). In conclusion, BIA, DEXA, TBW, and STK are equally valuable for estimating fat in those with tetraplegia.
