摘　　要：用排水法和皮褶厚度法对55～69岁的115名中老年人体脂含量进行了测量和比较,结果表明,两种方法测得值差异有显著性。用前一种方法测值与体围指标(X_1:前臂围、X_2:上臂围、X_3:小腿围,X_4:大腿围、X_5:腹围、X_6:臀围)、BMI(Body mass index)建立测体脂含量(F％)的回归方程,男性F％=-15.88+1.37BMI+0.0102Y,女性为:F％=-34.96+0.51BMI+0.1469Y,其中Y为X_1+X_2+X_3+X_4+X_5+X_6之和,BMI=体重(kg)/身高(m^2)。该回归方程提供了测定中老年人体脂含量的简易方法。 将体脂含量百分比(F％)划分肥胖法与按超体重百分比和BMI划分肥胖法进行比较,结果是:超体重百分比法划分肥胖率较F％法低,BMI法则较F％法高。The body fat measurements in old persons were carried out using two indirect methods; hydrostatic weighing and skinfold measurement.In comparison it was discovered that the skinfold measurement was significantly different from hydrostatic weighing method. Based on data of the circumference measurements which included forearm circumference (xl), arm circumference (x2), leg circumference(x3) thigh circumference(x4), abdomen circumference (x5) and buttock circumference(x6), two regression equations for the percentage of the body fat measurements were established as follows: male: F(%)=- 15.88 + 1.37BMI + 0.0102Y, female. F(%)= -34.9684 + 0.51BMI + 0.1469Y. Where Y = x1 + x2 + x3 + x4 + x5 + x6; BM1 (Body mass index) = weight(kg)/height(m)2Because the systematic error of skinfold measurements was bigger than those of circumference measurements, it was suggested that the above regression models could be used to estimate body fat in a simpler and easier way. At the same time the method of using percentage of body fat to classify obesity was compared with other two methods, excess body weight and BMI. The results showed that the rate of obesity based on BMI method was higher, and that based on excess body weight was lower than that of percentage of body fat measured by the water displacement method.
