Regression equations for estimating stature from anthropometric measurements of foot length and breadth in adults of efik ethnic group in cross river state

Abstract

INTRODUCTION: Estimation of stature is an important factor in forensic studies and occupies a foremost position in anthropometric research. The aim of the present work was to determine the reliability of foot dimensions in estimating stature in adult of Efik ethnicity in Cross River State. 
MATERIALS AND METHODS: The individuals comprised of 600 adult indigenes (300 males and 300 females) of Efi k ethnic group in Cross River State between the ages of 18–45 years. Student’s t-test, Pearson’s correlation, and Regression analysis were used to estimate the stature in the study population. 
RESULTS: Our results showed that stature in males had a mean value of 165.40 cm, whereas in females, it was 161.67 cm. More so, foot dimensions studied showed sexual dimorphism. Foot length in male individuals was 25.30 cm, while in females, foot length measured was 23.48 cm. Furthermore, the mean foot breadth in males was 9.20 cm, while in females, foot breadth was 8.37 cm. Statistical analysis revealed that the difference in foot length and foot breadth between males and females was statistically significant (P < 0.05). Furthermore, a positive correlation coefficient was observed between the foot dimensions measured and stature in both sexes. 
CONCLUSION: Regression equations formulated showed that foot breadth was a better predictor of stature in males while foot length was more reliable in predicting stature in females of Efik descent. 
These findings will be of immense benefit to physical anthropology and forensic studies.
