Abstract :The priority in creating biological profiles is sex estimation. The use of metric measurements in sex estimation has a long history. However, in the sex estimation studies using metric measurements, bones like the sternum have been less frequently examined compared to long bones. This study examined the accuracy rate of metric measurements taken from the sternum in sex estimation. A total of 62 adult individuals (24♀/38♂) from the Medieval Havuzdere (Yalova) population were examined. 4 different measurements (maximum manubrial width, manubrial width, manubrial length, corpus sterni length) were determined on the sternum bone, and 166 measurements were taken from a total of 62 sternum in the population. The data were analyzed using SPSS 23 program, applying the t-test, Wilks Lambda test, F-test, and Discriminant Function Analysis. Analysis results show that reliable accuracy was achieved in sex estimation based on sternum measurements. Accordingly, the manubrial width measurement at the sternum was 92.5% (93.8%♀/91.7%♂) respectively; corpus sterni length measurement was 85.3% (100%♀/78.3%♂); the manubrial length measurement was able to differentiate correctly at a rate of 74.5% (76.2%♀/73.3%♂). The lowest discrimination rate is the maximum manubrial width measurement with 73.8% (68.8%♀/76.9%♂). The accuracy of sex estimation was higher in 3 measurements for female and in 1 for male. When the measurements of the bones taken separately were evaluated together, the rate of correct sex determination generally increased. These findings highlight the potential of the sternum in sex estimation and contribute to forensic and bioarchaeological research.
