Basic studies for the practical uses of the A-mode type Ultrasonic Device

该首席研究员等人已经开发了一种使用A模式型超声设备测量皮下脂肪厚度的改进方法，使公共卫生活动的实际用途在三年内得以举行。1）为建立不同性别、年龄、部位的皮下脂肪厚度标准，对0 ~ 79岁男性1477例、女性1933例进行了测量。本文报告了平均值、标准差、最小值和最大值。2）为了使用超声测量的皮下脂肪厚度数据估计体脂量，研究者对50个样本进行了详细仔细的测量，建立了体脂量的估计公式，并在小于5%的显著性水平上进行了统计学检验在不久的将来，将能够获得日本人群肥胖的标准或皮下脂肪厚度的标准分布。

An improved method for measurement of subcutaneous fat thickness using an A-mode type ultrasonic device has been developed by this Head Investigator et al.,so that the practical uses for public health activities have been held during three years. The results are wound up as following two items:1) In order to set up the standard of the thickness of subcutaneous fat layer by sex, age and locations of body, the investigators measured 1477 male and 1933 female who consist of aged 0 to 79 years old. Mean,standard deviation ,minimum and maximum value were reported here.2) In order to estimate body fat mass using the data of subcutaneous fat thickness by ultrasonic measurement, detail careful measurement of 50 samples has been held by the investigators, and set up the estimation formula for the body-fat-mass which are tested statistically in the significance level less than 5%.It will be able to get criteria of obesity or standard distribution of subcutaneous fat thickness in Japnese population in very near future.
