Sex determination from adult human hip bone by direct discriminant function analysis

Bhaskar B.Reddy and M.A Doshi

Background: Determination of biological sex is one of the most important determinations to be made from human remains and is an essential first step in the development of the biological profile in forensics, anthropology and bioarchaeology. The aim of this study was to determine whether sexing of unknown adult human Hip bones can be done by applying values of morphometric parameters and formulae generated by present study on adult human Hip bones of known sex and to find out the best parameters for sex determination.

Methods: Various metric measurements were recorded using osteo metric board, measuring tape, non elastic thread, sliding calipers and vernier calipers on adult human Hip bones.

Results: Sex was correctly estimated by using direct discriminant function analysis, for the Hip bone 92.5 % of males and 84.2% of females, with a total accuracy of 89.4 %.

Conclusions: Present study exhibited better classification accuracy for multiple variables than those of single variables. In the Hip bone, the most discriminating variables in direct analysis is length of the hip bone.
