抄録

This study aimed to compare the accuracy of measurement values of subcutaneous fat thickness by two kinds of ultrasound measurement devices with different precision. Subjects were 48 healthy young males (age 20.6±1.4 years, height 173.2±5.2cm, weight 67.6±7.7kg) and 33 healthy young females (age 20.0±1.4 years, height 161.6±5.7cm, weight 56.3±4.9kg). Subcutaneous fat thickness on seventeen sites was measured twice across the entire body using two types of devices (ALOKA: SSD-900 and ELK: EU-2002B). The former has higher precision than the latter. Trial-to-trial reliabilities of measurement values by ALOKA and ELK devices were very high at over 0.81. No significant differences were found between their measurement values. Significant high correlations (r>0.70) were found in the following 11 items; chest, side of chest, abdominal, suprailiac, anterior region of thigh, triceps, subscapular, posterior region of thigh, biceps, outside of thigh, and inside of thigh. Significant moderate correlations (r=0.40-0.70) were found in the following eight items; zygomatic region, tongue bone region, patella region, lower thigh, upper part of back, and under part of back. No significant sex differences were found in any item. In summary, there were no significant differences between measurement values by ALOKA and ELK devices. We can measure 10 of 11 items, except the subscapular, which show a high correlation, with the same accuracy using the ELK device as the ALOKA device.
