Correlation of Human Height with Hand Dimensions: A Study among Medical students

Background: Anthropometry is widely used for Identification of an individual. Height is one of the most important parameters of anthropometry. It is strongly correlated with the individual’s hand dimensions and if either of the measurements are known, the other can be calculated. Aim and Objective: To know correlation between the hand dimensions and Height of an individual and to apply the regression line of height on hand dimension of the person. Methods and Material: A crosssectional study was conducted among the medical students. Anthropometric indices were recorded after obtaining written consent and institutional approval using standard equipments. Linear regression and Pearson coefficient were calculated to study the correlation and arrive at the equation to calculate Height from Hand length. Results: Age of the study participants who consented for study (150) ranged between 18-24 years. Mean height was 165.91 cm. Mean right hand length was 17.71 cm and 17.69 cm on left hand. Mean hand width was 7.79 cm on right side and 7.56 cm on left side. A statistically significant positive correlation was observed between height and the hand dimensions. Conclusions: There was a statistically significant positive correlation between hand dimensions and height. Forensic investigation, body identification and triage can be facilitated through calculating Height from hand dimensions when only mutilated body remains are received during disasters.

Estimation of stature from measurements of long bones, hand and foot dimensions.

Estimation of stature holds a special place in the field of Forensic anthropometry. The present study is an attempt to evaluate a possible correlation between stature of an individual & six parameters; hand-length, hand-width, foot-length, foot-width, forearm length & knee-to-ankle length individually in a local population of Mumbai. A sample of 300 medical students; 147 male & 153 female studying in Grant Medical College & Sir JJ Group of Hospitals was considered & measurements were taken for each of the parameters. It was found that all the six parameters showed a correlation with stature but at different degrees (significance calculated through the paired t-test). Forearm-length showed the highest degree of correlation (r = 0.6558) followed by foot-length (r = 0.6102). Knee-to-ankle length showed the lowest degree of correlation (r = 0.2086). Mathematical formulae for estimating stature were developed for each of these parameters through basic linear regression. It can be concluded that the present study has provided regression equations for six different parameters that can be used for stature estimation in the population of Mumbai. These equations should not be used for other Indian population groups.

THE NATURAL DEVELOPING PROCESS OF X-RAY MANIFESTATION IN CHILDREN WITH KASHIN-BECK DISEASE / 西安交通大学学报(医学版)

123 children with Kashin- Beck disease (KBD) and 84 normal children at the age of 2-13 in the KBD-affecter area have been continuously investigated for 4 years. It was found that 83% of KBD children had metaphyseal lesions and 66.9% of them had lesions in bone ends, and that the natural recovering rate of metaphyseal lesions from the 1st year to the 4th year was 22%, 43%, 57.8% and 73.6% respectively, and the natural recovely to the lesions of bone end was not found in all cases. It was also found that 25.2% of KBD children had an abnormal ratio of finger joint width and fingerwidth. Among them,2 changed from abnormal to normal and 17 from normal to abnormal. Only 2 children had an abnormal ratio of finger length and hand width. All the 84 normal children in the KBD-affected area had normal ratio of two ratios. No new case whose ratio turnd abnomal was found in 4 years. Our observations suggest that it is not reasonable to take the varying rate of metaphyseal lesions as the only evaluating criteria of cure and prevention of KBD because the natural recoveing rate of metaphyseal lesions is very high. It seems to be more reliable to combine the varying rate of metaphyseal leisions with the ratio of finger joint width and figer width as the evaluating criteria of cure and prevention of KBD.
