A Body Shape Index (ABSI) is a recently proposed index for standardizing waist circumference (WC) for body mass index (BMI) and height in adults, using 2/3 and 1/2 as scaling exponents, respectively. However, ABSI has limited applicability to children and adolescents, as the relationship between height and weight changes with age and varies according to sex. This study aimed to investigate whether ABSI can be applied to adolescents and to analyze the relationships among BMI, WC, height, weight, and body shape index (BSI) in Korean adolescents. The data of 1023 adolescents aged 10-19 years from the 2009-2012 Korea National Health and Nutrition Examination Survey were collected. Body measurements (height, weight, WC, and BMI) were analyzed to estimate the BSI using log-linear regression. The scaling exponents for standardizing WC for weight and height were estimated according to age (per year) and sex. The scaling exponents for standardizing WC for weight and height were 0.698 and -1.090 for boys and 0.646 and -0.855 for girls, respectively. The exponents also differed according to age. BSI was negatively correlated with height, weight, and BMI in boys and girls, and these correlations differed in direction from those in adults. ABSI cannot be applied to adolescents. In adolescents, the BSI is dependent on age and sex and is associated with growth and puberty. Further studies are required to evaluate the association between BSI and other biomarkers, to improve its applicability as a parameter for predicting the risk of chronic diseases in adolescents.
身体形状指数（ABSI）是最近提出的一种指数，用于根据体重指数（BMI）和成年人身高对腰围（WC）进行标准化，分别使用2/3和1/2作为缩放指数。然而，ABSI对儿童和青少年的适用性有限，因为身高和体重之间的关系会随着年龄变化，并且因性别而异。本研究旨在调查ABSI是否可应用于青少年，并分析韩国青少年中BMI、WC、身高、体重和身体形状指数（BSI）之间的关系。收集了2009 - 2012年韩国国家健康与营养检查调查中1023名10 - 19岁青少年的数据。通过对数线性回归分析身体测量数据（身高、体重、WC和BMI）以估计BSI。根据年龄（每年）和性别估计用于体重和身高标准化WC的缩放指数。男孩用于体重和身高标准化WC的缩放指数分别为0.698和 - 1.090，女孩为0.646和 - 0.855。这些指数也因年龄而异。男孩和女孩的BSI与身高、体重和BMI呈负相关，且这些相关性的方向与成年人不同。ABSI不能应用于青少年。在青少年中，BSI取决于年龄和性别，并且与生长和青春期相关。需要进一步研究以评估BSI与其他生物标志物之间的关联，以提高其作为预测青少年慢性病风险参数的适用性。
