A Model for Construction of Height and Sex from Shoulder Width, Arm Length and Foot Length by Regression Method

Abstract

Anthropometry is a systematic study of measurements on man and it involves scientific techniques for taking various measurements and somatic observations on the living man. As crime rate is increasing day by day, issue for human identification is of prime note. A forensic anthropologist would attempt to answer the following key questions relating to origin, age, sex, height and race after examining the remains. For instance height and sex determination is of utmost importance for human identification. No organized studies are yet available for sex and height estimation of people of Gujarat. The present study examines relationship between height and sex with shoulder width, arm length and foot length among two communities, Muslim and Hindu of Gujarat, India. A comparative study on measurements of shoulder width, arm length and foot length were taken among 160 adults (20-50 years) of which 80 were Muslim and 80 were Hindu of Gujarat. Linear and Multiple regression equations were calculated for determining height and it was observed that Hindu showed significantly higher correlation coefficient value (r) than Muslim of Gujarat. All the variables showed positive significance with male and gave higher mean values than female samples. Linear regression showed more reliable results compared to multiple regression analysis. Logistic regression models were prepared and were known that sex estimation from shoulder width in Hindu and from arm length in Muslim gives more reliable results compared to other measurements.
