死亡年龄估算方法在应用于成人骨骼遗骸时，提供了不准确的结果。这些老化方法通常依赖于对发生在特定关节的退行性变化的观察，然而，老化过程对人类骨骼的影响只是部分已知。因此，有必要增加我们对年龄相关变态过程的了解，以改进老化方法。这项研究的目的是确定骨盆骨关节上观察到的哪些与年龄相关的特征是相关的，并量化它们共同的退行性变化。因此，它旨在量化每个骨盆关节内各特征之间的退行性关系。分析了耻骨联合的15个年龄相关性状，髂骨耳廓表面的8个年龄相关性状，髋臼的6个年龄相关性状。骨盆关节的年龄相关特征被记录在来自两个参考收藏的成人骨骼上，威廉·巴斯捐赠的骨骼收藏和科英布拉收藏。主成分分析、年龄偏相关控制和Kendall‘s W协调系数被计算来确定性状之间的依赖程度。两个样本的性状间的相关性模式相似。其中一些性状具有高度到中等的相关性。然而，一些特征，如耳廓表面致密的骨，具有较高的独立性。结果表明，年龄估计方法应该考虑年龄相关特征的相关性和它们的依赖程度，这可能有助于在新的和修订的死亡年龄估计方法中建立更有效的评分系统。
Age at death estimation methods, when applied to skeletal remains of adults, have provided inaccurate results. These aging methods often depend on observations of the degenerative changes occurring at specific articulations, however, the effects of the aging process on the human skeleton are only partially known. Therefore a need exists to increase our understanding about the age related metamorphosis process to improve aging methods. The aim of this study is to determine which age-related traits observable on the pelvic bone articulations are correlated and to quantify their shared degenerative variance. Thus it is intended to quantify the degenerative relationship among features within each pelvic joint. Fifteen age related traits were analyzed for the pubic symphysis, eight traits for the auricular surface of the ilium, and six traits for the acetabulum. Age-related traits from the pelvic joints were recorded on adult skeletons from two reference collections the William Bass Donated Skeletal Collection and the Coimbra Collection. A Principal Components Analysis, partial correlation controlling for age, and a Kendall's W coefficient of concordance were calculated to determine the level of dependence among traits. A similar pattern of correlation amongst traits was obtained for both collections. Some of the traits shared a high to moderate correlation. However, some features, such as dense bone at the auricular surface, possessed a high independence from other traits. Results suggest that age estimation methods should take into consideration how age-related traits correlate and their level of dependence, which may possibly assist in the establishment of more effective scoring systems in new and revised age at death estimation methods.
