Carrying out a somatotype comparison of both, by using data of anthropometry of Hawaii-born Japanese Children (Hawaii-Children) and Amami-born Japanese Children (Amami-Children) that were carried out in 1977-78 a study with regard to the determination of obesity was carried out. The result that compared a somatotype was as follows. 1. The height of hawaii-Children was almost higher than that of Amami-Children. 2. A body weight was almost the same. 3. Trunk length of Amami-Children was longer than that of Hawaii-Children. 4. Lower limb length of Hawaii-Children was bigger than that of Amami-Children a little. 5. The letio of Rohrer index of Amami-Children was greater than that of Hawaii-Children. Therefore, it is determined that Amami-Children were obesity even from Hawaii-Children. when obesity index is judged from the ratio of the height to body weight. As for skin-fold thicknesses (amount of subcutaneous fat), Hawaii-Children is showing a high value more always than Amami-Children and Hawaii-Children is obesity obviously. Although the measurement result of Rohrer index and skin-fold thicknesses are contradicting this cause is because it differs with both trunk length and Lower limb length. Considering those result, it became obvious that a obesity index calculated from the height and body weight does not show fat volume inside a body precisely. The measurement of amount of subcutaneous fat needs to be carried out to check real obesity. Also, it is important to carry out the measurement of trunk length and Lower limb length in addition to the height and a body weight at least, to know a obesity.
利用1977 - 1978年对夏威夷出生的日本儿童（夏威夷儿童）和奄美出生的日本儿童（奄美儿童）进行的人体测量数据，对两者进行体型比较，并开展了一项关于肥胖判定的研究。体型比较结果如下：1. 夏威夷儿童的身高几乎高于奄美儿童。2. 体重几乎相同。3. 奄美儿童的躯干长度比夏威夷儿童长。4. 夏威夷儿童的下肢长度比奄美儿童略长。5. 奄美儿童的罗勒指数比率大于夏威夷儿童。因此，从身高与体重的比率判断肥胖指数时，可以确定即使与夏威夷儿童相比，奄美儿童也存在肥胖情况。至于皮褶厚度（皮下脂肪量），夏威夷儿童始终比奄美儿童显示出更高的值，且夏威夷儿童明显肥胖。尽管罗勒指数和皮褶厚度的测量结果相互矛盾，但原因在于两者的躯干长度和下肢长度不同。考虑到这些结果，很明显从身高和体重计算出的肥胖指数并不能精确显示体内的脂肪量。需要进行皮下脂肪量的测量来检查真正的肥胖情况。此外，为了了解肥胖情况，除了身高和体重外，至少还需要进行躯干长度和下肢长度的测量，这一点很重要。
