Abstract
Background: In the fields of bioarchaeology, forensic science, and physical anthropology, stature estimation is essential. It entails using quantifiable body factors to estimate or anticipate a person's height.
Aim: This study aims to investigate whether arm length, shoulder breadth, and foot length can be used to predict stature among the indigenous Yoruba people in Ibadan, Oyo State, Nigeria.
Method: The study employed a descriptive cross-sectional design; including 300 subjects (150 males and 150 females) aged 18 to 35 years. The anthropometric characteristics were measured using a mega-size calliper. The data were analysed using an IBM version of the Statistical Package for the Social Sciences (SPSS, version 23). Linear regression was employed to estimate gender and stature. A probability less than 0.05 (p<0.05) was considered statistically significant, with a 95% confidence level.
Result: A strong positive correlation existed in all subjects between stature, arm length, shoulder breadth, and foot length (R = 0.78, SEE = 4.968). The stature predictive power of males (R = 0.65) and females (R =0.73). Significant sexual dimorphism was noted in all parameters.
Conclusion: This shows a strong positive correlation between the subjects. These findings will be useful in forensic sciences, anthropology, medical sciences, and bioarchaeology.
