摘要

為釐清部位體組成在成長期之模式，俾有助於兒童肥胖之管理，本研究以生物電阻法測量685位日本國小學童（6-11歲）之體脂肪與肌肉組織。測量全身及身體不同部位的體脂率、脂肪質量及肌肉質量，並探究它們的成長模式。結果顯示，女生的全身體脂率較男生高，且隨年齡增長，差距越大。同時發現身體不同部位的體脂率、脂肪質量及肌肉質量之成長模式與性別差異和全身類似。在所有年齡層中，左肢的平均體脂率均較右肢高。在男生及女生中，身體質量指數與體脂率都存在很強的相關性。總之，在孩童期，體組成隨年齡的增長及性別間的差異，在所有身體部位都是相似的。慣用的肢體對體組成之效應在幼年就顯現。對於了解兒童時期體組成與監控肥胖狀況，累積身體各部位體組成之資料是必需的。

To clarify the growth pattern of body composition by body part for the management of childhood obesity, we measured body fat and muscle using BIA (bioelectrical impedance analysis) in 685 Japanese elementary schoolchildren (aged 6-11 years). The growth patterns of percentage body fat (%BF), fat mass (FM), and muscle mass (MM) were examined throughout the whole body and in various body parts. The %BF of the whole body was greater in females than in males, and this difference widened with age. The %BF, FM, and MM in each body part showed similar growth patterns and gender differences to those of the whole body. The mean %BF of the left limbs was higher than that of the right limbs at all age groups. BMI was strongly correlated with %BF in both sexes. In conclusion, the compositions of all body parts change similarly with age, and gender differences are also similar in childhood. The effect of one's dominant arm on body composition is seen at a young age. The accumulation of body composition data according to body part is indispensable for understanding childhood body composition and managing obesity.
