Skinfold callipers are often used in clinical practice to estimate subcutaneous adipose tissue thickness. Recently, LipoTool emerged as a potential digital system to measure skinfolds, however comparisons with competing equipment are lacking. The aim of this study was to test the agreement between two competing skinfold callipers (digital and mechanical). The sample included 22 healthy male adult participants. A certified observer measured eight skinfolds twice using different skinfold callipers (digital and mechanical). Differences between equipment were tested using Wilcoxon signed rank test The distribution of error was examined using the normality test Differences between skinfold callipers were significantly in five skinfolds: triceps (Z = -3.546; P < 0.001), subscapular (Z = -3.984; P < 0.001), suprailiac (Z = 3.024; P = 0.002), supraspinale (Z = 3.885; P < 0.001), abdominal (Z z = -2.937; P = 0.003), thigh (Z = -2.224; P = 0.026) and calf (Z = -2.052; P = 0.040). Differences between callipers were constant. Mechanical and digital callipers tended to record different values of skinfold thickness. Clinical examination should consider equipment-related variation in fat mass estimation.
皮褶卡尺常用于临床实践中估算皮下脂肪组织厚度。最近，LipoTool 作为一种潜在的数字系统用于测量皮褶厚度，但缺乏与竞争设备的比较。本研究旨在测试两种竞争皮褶卡尺（数字和机械）之间的一致性。样本包括 22 名健康成年男性参与者。一名经过认证的观察者使用两种不同的皮褶卡尺（数字和机械）两次测量了 8 个皮褶。使用 Wilcoxon 符号秩检验测试了设备之间的差异。通过正态性检验检查了误差的分布。两种皮褶卡尺在五个皮褶处差异显著：三头肌（Z=-3.546；P<0.001）、肩胛下（Z=-3.984；P<0.001）、髂嵴上（Z=3.024；P=0.002）、棘突上（Z=3.885；P<0.001）、腹部（Z z=-2.937；P=0.003）、大腿（Z=-2.224；P=0.026）和小腿（Z=-2.052；P=0.040）。卡尺之间的差异是恒定的。机械和数字卡尺往往记录不同的皮褶厚度值。临床检查应考虑脂肪量估计中与设备相关的变化。
