동아시아 청소년의 신체구성과 피하지방 분포

Abstract

The purpose of this study was to compare and analyze body composition and subcutaneous fat distribution in both sex of adolescents drawn from East Asia region. To achieve this purposes, a total of 3,205 adolescents 10-15 years old were selected and measured weight and height. Subcutaneous fat index was calculated by using body composition, body circumference, subcutaneous fat distribution values and Frisancho`s equations. South Korea and China showed higher significant level of height whereas Japan was lowest in four countries statistically. Percent body fat was higher in South Korea and Taiwan. If a man`s upper leg in South Korea and China were higher than in Japan and Taiwan, the Taiwanese women was higher than in the three countries. Arm circumference in men than in Japan, the three countries was high, women in South Korea than in Japan and Taiwan, respectively. WHR in men than in Taiwan, the three countries were higher, women were not statistically significant. Subcutaneous fat thickness showed a statistically South Korea and Taiwan. Arm muscle area in China was significantly higher than the three countries. Including the most commonly used measure of obesity, BMI, we found that, South Korea and Taiwan had significantly more body fat, body size and fat distribution than their counterparts. This result demonstrates that the proper nutrition management and lifestyle should be given by both individual and national level not only to address imbalance between ingestion and consumption, but also to help set healthy lifelong body composition.
