ABSTRACT
Background: The estimation of gender using hand dimensions is a crucial role in forensic investigation and legal sciences. Objectives: In this study, the mean score of hand measurements have been derived and linear discriminant analysis has been applied to predict gender from hand dimensions. An Independent t-test has been employed to know discrimination between male and female. The accuracy of gender estimation has been derived and checked by ROC curve. Material and Methods: A sample of 150 participants has been collected for the completion of this study, where 78 males and 72 females were found aged between 18 and 24 years. The breadths and lengths of left and right hands of the participants have been measured. Results: Respondents’ mean score of length and breadth of left hand were found 17.69 ± 1.30 and 7.56 ± 1.17, respectively. It was found to be significantly different in the respondents’ mean scores of males and females. Conclusions: The hand dimensions of males were higher than females. The prediction of a number of females and males were 76 and 74, respectively, and its accuracy was observed 0.87. This research can be applied for larger sample and would be helpful in predicting gender discrimination among adults through hand dimensions.
ABSTRACT
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.
