Estimation of stature from hand dimensions of north and south Indians.

The present study was undertaken to predict the stature of a person using hand length and breadth. The study includes 500 right-hand dominant medical students aged between 20 and 30 years, from northern and southern parts of India, studying in Kasturba medical college, Manipal, India. Hand length was measured 'between the distal wrist crease and the tip of middle finger (HL-1)' and 'between the mid-point of inter-styloid line to the tip of middle finger (HL-2)'. Hand breadth was measured between radial side of the second metacarpophalyngeal joint and ulnar side of the fifth metacarpophalyngeal joint (HB). No significant difference was present in hand dimensions between north and south Indians. When compared between both hands, right-hand dimensions were larger than the left hand, with statistically significant difference in HL-2 and HB. Linear regression equations using hand length is more helpful in estimating stature than the hand breadth. The correlation coefficients ranged from 0.673 to 0.665 and 0.740 to 0.732 in north Indian males and females, respectively. Whereas in south Indians, it ranged from 0.752 to 0.732 and 0.701 to 0.691 in males and females, respectively. Multiple regression equations give better results than linear regression equations. HL-2 gives more accurate results in stature estimation than the HL-1.
