American population consists of people of various race and ethnic group. Palm prints are different from each individual, ethnic group and race. The aim of this study is to investigate influencing anthropometric values to atd angles formed by triradii of palm prints in European American and develop a regression equation that can predict atd angle.
This study was done on 208 European American (males: 102 individuals, females: 106 individuals). Data were collected by measuring atd angles using a protractor, distance from triradii a to d, length from triradius t to the distal wrist crease (DWC), palm breadth at metacarpals and palm length perpendicular using digital callipers. The data were analyzed by descriptive statistics, the frequency, independent sample t-test, paired t-test, Pearson correlation analysis, stepwise regression using SPSS win 18.0.
This study showed that atd angles of males (38.6˚) are significantly smaller than those of females (40.4˚). Influencing anthropometric values to atd angles in males were distance from triradii a to d, the ratio of the length from triradius t to the DWC to palm length, palm length. Influencing anthropometric values to atd angles in females were the ratio of the length from triradius t to the DWC to palm length, the ratio of the distance from triradii a to d to palm breadth, and the ratio of palm breadth to palm length. In addition to, the regression equation predicted atd angle of males was 26.150+(0.741×distance from triradii a to d)+(52.856×the ratio of the length from triradius t to the DWC to palm length)-(0.332×palm length), on the other hand, that of females was -42.935+ (51.657×the ratio of the length from triradius t to the DWC to palm length)+(63.314×the ratio of the distance from triradii a to d to palm breadth)+(42.764×the ratio of palm breadth to palm length).
The results of this study suggest that there were differences in influencing anthropometric values to atd angles between males and females in European American. Especially, the ratio of the length from triradius t to DWC to palm length was a very significantly influencing anthropometric value to atd angles to all of males and females.
