Correlation of Atd-Angle Between non-Insulin Dependent Diabetes Mellitus and Normal Individuals in Bangladeshi Population

Dermatoglyphics is the study of configuration of the epidermal ridges in palms, soles and digits. Development of dermatoglyphic pattern in under genetic control, it does not change throughout the life once development being completed. As a diagnostic aid, Dermatoglyphic pattern analysis can successfully predict onset of many diseases, which has a strong hereditary basis. Diabetes mellitus (DM) is a condition of partial genetic background. The aim of this study was to compare the atd-angle of dermatoglyphicsin order to identify as a risk factor to predict diabetes in future.This observational cross-sectional study was conducted in Sylhet MAG Osmani Medical College from July 2018 to June 2019. There were a total of 200 subjects recruited in this study; among them 100 were healthy individuals and the rest 100 were the diagnosed patients of type II DM.The studied groups were matched for age and sex of the study subjects. Paper and ink method was used for making print of fingers and palms. The prints were examined using mounted hand lens. The mean atd-angle was higher in cases in both hands compared to the control. On the left hand, the mean 43.23±2.14 in cases and 41.11±1.65 in control; and 42.87±2.25 in cases and 41.19±1.89 in control on the right hand. Unpaired t-test showed statistical significant mean differences between the studied groups both in left hand (t = -7.844, p = <0.001, 95% confidence interval: -2.651 to -1.585) and right hand (t = -5.749, p = <0.001, 95% confidence interval: -2.267 to -1.109). So,based on the result of this study, it can be concluded that the atd-angle would be a helpful parameter to find out high risk individuals for NIDDM in future.
