Regression Formula for Stature Determination from Percutaneous Tibial Length among the Female Meitei Population of Manipur

Abstract

Stature is one of the important parameters for personal identification when only parts of human body, such as
limbs are available for identification as in cases of natural disasters, rail and aircraft accidents, wars and terrorist
bombings. Studies have reported significant differences in proportion of limb dimensions due to hereditary,
environmental, ethnic and dietary factors, which also influence the stature of a person. Therefore, populationspecific
formulae are necessary for estimation of stature in medico-legal cases. A cross-sectional study was
conducted on Indigenous Manipuri Meitei female subjects between the age group of 21-25years. ‘Meitei’
is the majority community in the state. The calculated sample size was 72. Considering a dropout rate of
5%, a total of 75 Meitei female subjects were studied in Department of Forensic Medicine and Toxicology,
Regional Institute of Medical Sciences, Imphal. The study period was from August 2018 to July 2020.
The findings of the study have been used in estimating the stature from Tibial Height by deriving a new
Regression Formula which is specific for the population. The following is the developed regression equation
of stature of female (Y) on her tibial length (X): Y= 107.83 + .60 X +.71. It will be of immense importance
in medico-legal investigations thereby benefitting the society in general.
