ABSTRACT

Stature estimation is an important aspect of physical anthropology and forensic science, especially when long bones are missing or fragmented, necessitating alternative skeletal indicators. The sternum, due to its location in the chest, is relatively resistant to damage and may be useful in forensic identification. However, no research for stature estimation using the sternum in Korean population has been reported. Therefore, this study aims to analyze the relationship between sternal length and stature and propose equation of statue estimation in Korean population. 56 formalin-fixed Korean adult cadavers (38 males, 18 females, mean age 79.2±10.3 years) were used for this study. The length of manubrium (M), length of body (B), and combined length of sternum (CL) and the stature were measured. Descriptive statistics for all variables were calculated, and comparisons by sex were analyzed using independent samples t-test. The correlation between sternum length and stature was analyzed using Pearson’s correlation analysis. To prove the measurement variables with the highest correlation and their effects on stature, simple linear regression analysis and multiple linear regression analysis were used to derive a regression equation for estimating stature. Both B and CL showed significant positive correlations with stature in males, females, and the total sample (p<0.05). B showed the highest correlation (males R = 0.748, females R = 0.573, total R = 0.719) and showed the lowest standard error of estimate (SEE) in regression analysis, indicating the highest accuracy. Multiple regression analysis demonstrated that combining B and CL increased accuracy in males and in the total sample. This study proposed the first regression equations for stature estimation from sternal length in Koreans. In particular, B was the most powerful candidate for stature estimation in Koreans. For male, Stature = 1218.964 + 5.110 × B - 0.634 × CL, and for female, Stature = 1367.617 + 2.232 × B - 0.202 × CL. This formula may be more appropriate and useful in forensic identification and anthropological research for the Korean population.
