A study was conducted to evaluate body composition by hydrostatic weighing, skinfold thickness, and body mass index (BMI) in 102 senior high school girls, aged 15 to 18 in Nagasaki City. Body density measured by the underwater weighing method, was used to determine the fat weight (Fat) and lean body mass (LBM. or fat free weight: FFW) utilizing the formulas by Brozek et al. The results were as follows; 1. Mean values of body density were 1.04428 in the first grade girls, 1.04182 in the second grade, and 1.04185 in the third grade. 2. Mean values of percentage body fat (%Fat) were 23.5% in the first grade, 24.5% in the second and 24.5% in the third. 3. Percentage body fat (%Fat), lean body mass (LBM) and LBM/Height were not significantly with different advance of grade from the first to the third. 4. The correlation coefficients between percent body fat and the sum of two skinfold thicknesses, the sum of three skinfold thicknesses and the sum of seven skinfold thicknesses was 0.78, 0.79, and 0.80 respectively and were all statistically significant (p < 0.001). 5. The correlation coefficients between BMI and the sum of two skinfold thicknesses, the sum of three skinfold thicknesses and the sum of seven skinfold thicknesses was 0.74, 0.74, and 0.74 respectively and were all statistically significant (p < 0.001). 6. Mean values of BMI, Rohrer index and waist-hip ratio (WHR) in all subjects (n = 102) were 20.3, 128.2 and 0.72 respectively.
一项研究旨在通过水下称重法、皮褶厚度测量法和身体质量指数（BMI），对长崎市102名年龄在15至18岁的高中女生的身体成分进行评估。通过水下称重法测量的身体密度，被用于利用布罗泽克等人的公式来确定脂肪重量（Fat）和去脂体重（LBM，或无脂肪体重：FFW）。结果如下：1. 一年级女生的身体密度平均值为1.04428，二年级为1.04182，三年级为1.04185。2. 一年级女生的体脂百分比（%Fat）平均值为23.5%，二年级为24.5%，三年级为24.5%。3. 从一年级到三年级，体脂百分比（%Fat）、去脂体重（LBM）和LBM/身高并没有随着年级的升高而出现显著差异。4. 体脂百分比与两个皮褶厚度之和、三个皮褶厚度之和以及七个皮褶厚度之和之间的相关系数分别为0.78、0.79和0.80，且均具有统计学意义（p < 0.001）。5. BMI与两个皮褶厚度之和、三个皮褶厚度之和以及七个皮褶厚度之和之间的相关系数分别为0.74、0.74和0.74，且均具有统计学意义（p < 0.001）。6. 所有受试者（n = 102）的BMI、罗勒指数和腰臀比（WHR）平均值分别为20.3、128.2和0.72。
