至关重要的是，骨骼生物学家和法医人类学家随着时间的推移观察人口，以便发现和监测变化。本研究的目的是确定骨骼中是否存在明显的时间变化，如果是，则制定适当的标准来确定日本当代居民胫骨的性别。骨骼测量数据来自东京Jikei医科大学的84具日本人骨骼。这些收藏品是在1960-1970年间从解剖室收集的。男性的平均年龄约为56岁，女性为51岁，这个样本代表了经历过二战的个体。7胫骨测量，并进行SPSS-X判别函数分析。结果表明，近端和远端宽度测量被选为最具鉴别力的逐步程序。此外，还使用了一些测量组合来开发适用于碎骨的公式。平均预测准确率范围从最小干周长的80%到近端骺宽度的89%。男性的分类准确率（96%）高于女性（79%）。与早期对日本人的研究相比，Jikei胫骨更长，尤其是在女性中，因此表现出较少的性二型性。目前的研究提供了更好地反映当今日本人的新标准。此外，与早期基于长度的公式不同，这些结果允许从碎片骨骼中进行性别鉴定。
It is vital that skeletal biologists and forensic anthropologists observe populations over time so that changes can be detected and monitored. The purpose of this study is to determine if temporal changes are manifest in the skeleton and, if so, develop appropriate standards to determine sex from the tibia in the contemporary inhabitants of Japan. Osteometric data were obtained from 84 recent Japanese skeletons located at Jikei Medical University, Tokyo. The collection was assembled from the anatomy dissecting room between 1960-1970. With a mean age of about 56 years for males and 51 for females, this sample represents individuals who lived through WWII. Seven tibial measurements were taken and subjected to SPSS-X discriminant function analysis. Results indicated that proximal and distal breadth measurements were selected by the stepwise procedure as the most discriminating. In addition, a number of combinations of measurements were used to develop formulae that would be suitable for fragmentary bones. Average prediction accuracy ranged from 80% from minimum shaft circumference to 89% with proximal epiphyseal breadth. Classification accuracy was higher in males (96%) than in females (79%). Compared with earlier studies of the Japanese, Jikei tibiae are longer, especially in females and thus exhibit less sexual dimorphism. The present research provides new standards that better reflect the Japanese people of today. Furthermore, unlike earlier length based formulae, these results allow sexing from fragmentary bones.
