Ultrasound (A-scan mode) and skinfold methods were evaluated in the measurement of subcutaneous fat thickness and prediction of total fat weight (by whole body potassium counting). Based on intraobserver correlations on 39 men at 15 body sites, skinfold caliper measurements were more reproducible than ones obtained by ultrasound. Measurements made with the two techniques at the same site typically produced different mean estimates of fat thickness. However, scores were often highly correlated with each other, indicating similar relative rankings of subjects by each technique. Skinfolds were more highly correlated with total fat weight than were ultrasound measurements, but body weight. Anthropometric measurements were highly correlated with fatness because of their association with body weight, and when this relationship was statistically controlled for, they typically lost their predictive effectiveness. Multiple regression analyses revealed that the best predictors of fat weight were body weight along with skinfold and ultrasound measurements. These results suggest that skinfolds are a more effective means of assessing subcutaneous fat than ultrasound, especially when the large difference in cost of equipment is considered.
对超声（A 扫描模式）和皮褶厚度测量法进行了评估，以测量皮下脂肪厚度并预测总脂肪重量（通过全身钾计数法）。基于 39 名男性在 15 个身体部位的观察者内相关性，皮褶卡尺测量比超声测量更具重复性。在同一部位使用这两种技术进行的测量通常会得出不同的脂肪厚度平均估计值。然而，两种技术的得分往往高度相关，表明每种技术对受试者的相对排名相似。皮褶厚度与总脂肪重量的相关性高于超声测量，但与体重的相关性则不然。人体测量与肥胖高度相关是因为它们与体重有关，当这种关系在统计上得到控制时，它们通常会失去预测效力。多元回归分析表明，脂肪重量的最佳预测指标是体重以及皮褶厚度和超声测量值。这些结果表明，皮褶厚度是比超声更有效的评估皮下脂肪的方法，尤其是考虑到设备成本的巨大差异时。
