Abstract

Like other phenotypic traits, stature is a key indicator for identification and is influenced by a combination of genetic and environmental factors. With the alarming rise in the frequency of road, flood, intentional mutilation, and natural disasters, stature or body height is one of the most significant and useful anthropometric parameters that establish a person's physical identity. It is also regarded as one of the important and significant parameters for the establishment of personal identity in forensic medical examination or anthropological studies. To determine stature and gender in an adult Nigerian population by measuring the percutaneous length of the arm and forearm bones. The University of Lagos' workers, students, and volunteers made up the sample group for this study, which included 222 people (115 men and 107 women) between the ages of 18 and 65. a variety of anthropological tools, including the Stadiometer, an anthropometric tool produced by SECA alpha® in Germany. The measurement was performed using calliper, weighing balance, and tape that were calibrated in centimetres. The intercondylar breadth had the best value for statistical significance in the sex prediction made using logistic regression. The largest link with stature was found for the ulnar measurement, whereas the smallest correlation was found for the intercondylar measurement across all parameters. Both males and females can have their arm and forearm lengths measured percutaneously, which has good reliability for estimating stature and predicting sex. The intercondylar is more strongly correlated with sexual dimorphism. Simple and numerous linear regressions demonstrated that using the foot length is the most accurate technique to predict and estimate stature.
