Sex is one of the critical questions addressed when unidentified skeletal remains are discovered in forensic or archeological contexts. Continuous testing and re-evaluation of existing techniques is essential to improve accuracy and precision. The Wescott (J Forensic Sci 2000;45(2):462-6) method of sex determination from dimensions of the second cervical vertebra was blind-tested on 153 adult individuals from the Spitalfields documented collection of human skeletal remains held at the Natural History Museum, London. Significant sex differences were determined for all dimensions measured (independent two-sample t-test, p<0.05-0.001). The discriminant functions developed by Wescott were shown to have an overall accuracy of classification of 76.99%. Using stepwise discriminant analysis, a discriminant function based on the Spitalfields data correctly classified sex in 83.3% of individuals and was able to classify males and females with equal accuracy. Additional discriminant functions are presented for use in instances where preservation of the second cervical vertebra is poor.
当在法医或考古背景下发现身份不明的骨骼遗骸时，性别鉴定是关键问题之一。持续测试和重新评估现有技术对于提高准确性和精确性至关重要。对来自伦敦自然历史博物馆保存的斯皮塔菲尔德记录的人类骨骼遗骸集合中的153名成年人，采用韦斯科特（《法医科学杂志》2000年；45(2):462 - 6）从第二颈椎尺寸确定性别的方法进行了盲测。对所有测量维度确定了显著的性别差异（独立双样本t检验，p<0.05 - 0.001）。韦斯科特开发的判别函数显示总体分类准确率为76.99%。使用逐步判别分析，基于斯皮塔菲尔德数据的判别函数在83.3%的个体中正确分类了性别，并且能够以相同的准确率对男性和女性进行分类。还给出了在第二颈椎保存不佳的情况下使用的其他判别函数。
