Estimation of Stature by using the Length of Ulna in Tribal Male Population of Udaipur District: A Cross-sectional Study

Abstract

Introduction: Anthropometry is one of the traditional and conceivably the basic tool of biological anthropology. Height is an important identifying feature of an individual. Estimation of height can be done by measurement of ulna and various regression formulae have been derived by different authors for different regions. Aim: To define correlation and to derive the linear regression equation from the length of ulna in male tribal population of Udaipur region, Rajasthan, India. Materials and Methods: The present cross-sectional study was conducted at Geetanjali Medical College and Hospital, Udaipur, Rajasthan, India, from February 2019 to January 2020. Male tribal population between the age of 20-40 years, in and around Udaipur district of Rajasthan, were included in this study. Measurement of ulnar length of both right and left sides were recorded along with their height. ANOVA test was done to find out the correlation between height and ulnar length. Regression equation was formulated for the study population. Results: Total 245 males, belonging to Bhil and Meena tribes of Rajasthan, of mean age 31.87 years, were included in this study. The mean length of right ulna was 25.52 cm, of left ulna was 25.82 cm, and mean height was 159.34 cm. The study showed a positive correlation between the length of ulna and total height of male population of Udaipur region, in which the correlation coefficient of right ulna with height was 0.61, and that of left ulna with height was 0.64. Conclusion: A positive correlation exists between the length of ulna and height of an individual.
