Abstract
BackgroundDiabetes mellitus (DM) is a complex metabolic disorder characterized by persistent hyperglycemia resulting from defects in insulin secretion, insulin action, or both. Type 2 DM has a strong hereditary background. A study of the dermatoglyphic features can help in the early identification of people with a genetic predisposition to develop type 2 DM.Purpose of the StudyThe study was aimed to compare the finger and palmar dermatoglyphics features in type 2 diabetic and non-diabetic patients and to evaluate the association with other variables.Patients and MaterialsInstitution-based cross-sectional study was conducted in one referral hospital and three primary hospitals located in Gedeo Zone. Three hundred ninety study participants (130 type 2 diabetics and 260 non-diabetics) from adult OPD and diabetic clinics were included in the study. The association among different dermatoglyphics variables was analyzed using the chi-square test. An independent t-test was conducted to analyze the mean difference and to test the significance of numerical variables. A statistically significant association was declared at P-value <0.05.ResultsIn the present study, a total of 3900 digits (1300 from type 2 diabetic and 2600 non-diabetic) were analyzed for distribution of digital dermatoglyphic patterns. Loop pattern is found to be the commonest in both study groups with a prevalence of 65.8% and 60.7% among type 2 diabetics and non-diabetics, respectively. Both the right-left axial tri-radius angle was significantly higher in type 2 diabetes mellitus patients compared to non-diabetic study participants. Total finger ridge counts and absolute finger ridge counts showed no significant difference in both groups.ConclusionThe study revealed Loop pattern was more frequent in type 2 DM compared to non-diabetic study participants. Whorl type was more common than arch type in non-diabetic patients compared to type 2 DM groups. The result also showed tri-radius angle is significantly wider in diabetic groups in both hands.
