Accurate age estimations are essential for identifying human skeletal remains and narrowing missing persons searches. This study examines how BMI, body mass, and stature influence inaccuracy and bias in adult skeletal age estimations obtained using eight methods. 746 skeletons from the Hamann-Todd and William Bass Collections were used. Underweight BMI, light body mass, and short-stature individuals have the most error associated with their age estimates and are consistently under-aged between 3 to 13years. Obese BMI, heavy body mass, and tall-stature individuals are consistently over-aged between 3 to 8.5years. The most reliable methods for smaller-bodied individuals are Kunos et al. (first rib) and Buckberry-Chamberlain (auricular surface); for individuals in the average range, İşcan et al. (fourth ribs) and Passalacqua (sacrum); and for larger-bodied individuals, İşcan et al., Passalacqua, and Rougé-Maillart et al. (auricular surface and acetabulum). Lovejoy et al. (auricular surface) and Suchey-Brooks (pubic symphysis) produce consistent inaccuracy and bias scores across all body size groups. The least reliable method for smaller-bodied individuals is İşcan et al.; for larger-bodied individuals, Buckberry-Chamberlain; and across all body size groups, DiGangi et al. (first rib).
准确的年龄估计对于识别人类骨骼遗骸和缩小失踪人员搜索范围至关重要。本研究考察了体重指数（BMI）、体重和身高如何影响使用八种方法得出的成人骨骼年龄估计中的误差和偏差。研究使用了哈曼 - 托德（Hamann - Todd）和威廉·巴斯（William Bass）收藏的746具骨骼。体重过轻、体重较轻和身材矮小的个体在年龄估计上的误差最大，且始终被低估3至13岁。肥胖、体重较重和身材高大的个体始终被高估3至8.5岁。对于体型较小的个体，最可靠的方法是库诺斯等人（第一肋骨）和巴克伯里 - 张伯伦（耳状面）的方法；对于中等体型个体，是伊什坎等人（第四肋骨）和帕萨拉夸（骶骨）的方法；对于体型较大的个体，是伊什坎等人、帕萨拉夸以及鲁热 - 马亚尔等人（耳状面和髋臼）的方法。洛夫乔伊等人（耳状面）和苏奇 - 布鲁克斯（耻骨联合）在所有体型组中产生的误差和偏差分数较为一致。对于体型较小的个体，最不可靠的方法是伊什坎等人的方法；对于体型较大的个体，是巴克伯里 - 张伯伦的方法；而在所有体型组中，最不可靠的是迪甘吉等人（第一肋骨）的方法。
