Facial characteristics may provide reliable information giving an insight into the inner nature of an individual. This study examines the differences in widely used facial metrics, including cheek-to-jaw width ratio (CJWR), width-to-height ratio (WHR), perimeter-to-area ratio (PAR), and facial masculinity indexes across Sasang constitutional types, to investigate the association between these facial cues and body mass index (BMI) and develop a predictive model for Sasang typing. 2D images of 911 participants were analyzed. The results indicated that TaeEum (TE) type generally has a squarer face, with the male TE type having a squarer and wider face than that of both SoYang (SY) and SoEum (SE) types. Male TE type has longer eyes than that of the SE type, and the lower face of the female TE type is longer than that of the SY type. PAR, WHR, CJWR, and eye size had associations with BMI, and the magnitude of correlation of CJWR in Korean men were twofold higher than that of the Caucasian and African men. BMI and facial metrics including PAR, WHR, CJWR, and eye size were good predictors for TE type, and the most parsimonious model for TE typing included BMI and CJWR with high predictive performances.
面部特征可能提供可靠的信息，深入了解个体的内在本质。本研究检验了广泛使用的面部指标，包括颊宽与下颌宽比（CJWR）、宽高比（WHR）、周长与面积比（PAR）和面部男性化指数在四种不同的 Sasang 体质类型之间的差异，以探讨这些面部线索与体重指数（BMI）之间的关联，并为 Sasang 体质分型开发预测模型。对 911 名参与者的 2D 图像进行了分析。结果表明，TaeEum（TE）型通常具有更方形的脸，男性 TE 型的脸比 SoYang（SY）和 SoEum（SE）型更方且更宽。男性 TE 型的眼睛比 SE 型长，女性 TE 型的下面部比 SY 型长。PAR、WHR、CJWR 和眼睛大小与 BMI 有关，韩国男性的 CJWR 相关性的幅度是白人和非洲男性的两倍。BMI 和包括 PAR、WHR、CJWR 和眼睛大小在内的面部指标是 TE 型的良好预测因子，TE 型分型的最简约模型包括 BMI 和 CJWR，具有较高的预测性能。
