Estimation of stature from hand dimensions in Bengalee population, West Bengal, India

Stature estimation from decomposing bodies and incomplete skeletons particularly in personal identification is considered as one of the biggest aspects of forensic science. This issue has gained importance in recent times due to mass disasters like terrorist attacks, mass murders, transport accidents, floods and earthquakes. Thus, the present study was undertaken to set up a standard formulae to estimate stature from hand dimensions in the Bengalee population. Measurements of different hand dimensions and statures were taken from 1662 adult Bengalee women aged from 20 to 40 years following the standard technique and appropriate landmarks. There was no statistically significant bilateral variation of the measurements. The correlation coefficients between stature and all variables were positive and statistically significant (p < 0.001). The hand length and palm length showed a better correlation with stature than the other variables. Simple linear regression equations and multiple linear regression equation were formulated for stature estimation using the hand dimensions. The derived equations were applied to the control group and it was noted that the percentage difference between true stature of the control and the estimated stature ranged from 0.01% to 0.15%. The multiple linear regression equation was more reliable than the simple linear regression equations as a lower standard error of estimate and higher value of determination coefficient and multiple correlation coefficient. From the results of the present study, it may be concluded that hand dimensions can be successfully used for estimating stature of adult Bengalee women in forensic practice by enforcement agencies and forensic scientists.
