共有117名日本人（62名男性和55名女性）自愿参加了这项研究。采用b超测量体表9个部位皮下脂肪组织（AT）和肌肉厚度。氢密度法测定体密度（BD）。超声测量厚度的重现性高（r = 0.96 ~ 0.99）。男性AT厚度与BD的相关性为-0.46（腓肠肌）~ -0.87（腹部），女性为-0.46（腓肠肌）~ -0.84（腹部）。男性和女性的AT厚度（前臂、肱二头肌、肱三头肌、腹部、肩胛下肌、股四头肌、腘窝肌、腓肠肌和胫骨前肌）的总和均存在较高的负相关（r = -0.89）。肌肉厚度与腰厚之间的系数略低（男性r = 0.36 ~ 0.70，女性r = 0.44 ~ 0.55）。通过多元回归分析，得到由AT和肌肉厚度预测BD和LBM的方程。在一个单独的样本（33名男性和44名女性）的交叉验证中，b超可以准确预测BD。本研究结果表明b超可以应用于临床评估和现场调查。(C) 1994 Wiley-Liss, Inc。
A total of 117 Japanese subjects (62 men and 55 women) volunteered for the study. Subcutaneous adipose tissue (AT) and muscle thicknesses were measured by B-mode ultrasonography at nine sites of the body. Body density (BD) was determined the hydrodensitometry. Reproducibility of thickness measurements by ultrasonography was high (r = 0.96-0.99). Correlations between AT thickness and BD ranged from -0.46 (gastrocnemius) to -0.87 (abdomen) for males and -0.46 (gastrocnemius) to -0.84 (abdomen) for females. A higher negative correlation (r = -0.89) was observed for the sum of AT thicknesses (forearm, biceps, triceps, abdomen, subscapula, quadriceps, hamstrings, gastrocnemius, and tibialis anterior) both in males and in females. Slightly lower coefficients were observed between muscle thickness and LBM (r = 0.36 to r = 0.70 for males and r = 0.44 to r = 0.55 for females). Prediction equations for BD and LBM from AT and muscle thickness were obtained by multiple regression analysis. Cross-validation on a separate sample (33 men and 44 women) showed an accurate prediction for BD. The present findings suggest that B-mode ultrasonography can be applied in clinical assessment and field surveys. (C) 1994 Wiley-Liss, Inc.
