Abstract

The aim of the study was to estimate the stature from lower limb parameters in the north-west population of India and to know whether a significant correlation exists between the stature and various lower limb dimensions and to further derive regression formulae for estimation of stature from various lower limb segments. Materials and methods: the study was conducted on medical students age ranged between 18 to 28 years, which comes chiefly from north-west part of India. Only the subjects willing to participate in the study and given their written informed consent were included in the study group. The students having any obvious physical deformity were excluded from the study. Correlations between various lower limb parameters and stature were determined by using the Pearson’s correlation test. Sex-specific linear regression equations for stature estimation were developed using the lower limb measurements. The multiple regressions equations were produced based on various combinations of the parameters by stepwise regression analysis. Results: the Pearson’s correlation in combined group showed good correlations between lower limb parameters and stature. There was no statistically significant difference between known stature and estimated stature by using paired T-test for both right and left side in a group consisting of both sexes and in males (p>0.05). Conclusion: from the parameters, lower limb length and foot length had shown strong positive correlations with stature in the north-west Indian population

Highlights

Identification or determination of individuality is the fundamental right of human being whether live or dead
In our study strong positive correlation was observed between lower limb length (r=0.65) and foot length (r=0.51) with stature in a group consisting of both sexes, while moderate degree of association observed knee ankle length (r=0.43) and foot breadth (r=0.40 for right side and r=0.42 for left side) with the stature
Moderately strong positive correlation was observed between lower limb length (r=0.40 for right side and r=0.38 for left side), knee ankle length (r=0.30) and foot length (r=0.33 for right side and r=0.34 for left side) with stature, while low degree of association observed between foot breadth with the stature (r=0.25 for right side and r=0.26 for left side) (Table 3)

Summary

Introduction

Identification or determination of individuality is the fundamental right of human being whether live or dead. The stature of an individual is an inherent characteristic; its estimate is considered to be an important assessment in the identification of unknown human remains [2]. Several studies have been conducted in different regions of the country and worldwide to estimate stature from various body segments. It was opined more than 50 years ago that regional studies on stature estimations were very much needed due to racial and ethnic variations present indifferent regions of the world [3]. India is comprised of a substantial number of ethnic and indigenous groups, and its ethnic and genetic diversity is enormous It has the largest number of indigenous people in the world [5]
