Age-related changes of the pubic symphysis have gained wide acceptance among physical anthropologists as one basis for estimating adult skeletal age. However, these methods have not been tested by independent observers on large samples with known ages at death that represent contemporary populations. In this study 202 female and 116 male pairs of pubes collected at autopsy were blindly evaluated for age using the McKern-Stewart or Gilbert-McKern and Suchey-Brooks methods. Performance of the methods was measured by mean absolute deviation of true age from scored interval means and frequencies of true age falling within +/- 1 and +/- 2 standard deviations from the mean. The results suggest that the Suchey-Brooks methods are superior in forensic applications and that the racially specific refinement for males should be used. Age estimates should include +/- 2 standard deviations, and chances of error should be considered, especially when advanced age or debilitation is suspected.
耻骨联合的年龄相关变化已被体质人类学家广泛认可，作为估计成人骨骼年龄的一个依据。然而，这些方法尚未由独立观察者在具有已知死亡年龄且代表当代人群的大样本上进行测试。在本研究中，对尸检时收集的202对女性耻骨和116对男性耻骨，采用麦肯-斯图尔特法或吉尔伯特-麦肯和苏切伊-布鲁克斯法进行年龄的盲法评估。通过真实年龄与评分区间均值的平均绝对偏差以及真实年龄落在均值±1和±2标准差范围内的频率来衡量这些方法的性能。结果表明，苏切伊-布鲁克斯法在法医应用中更具优势，并且应使用针对男性的种族特异性改进方法。年龄估计应包括±2个标准差，并且应考虑出错的可能性，尤其是在怀疑年龄较大或身体虚弱的情况下。
