A Cross Sectional Study of Correlation of ATD Angle with Body Fat Distribution in North Indian Population
Keywords:Obesity, Dermatoglyphics, BMI, anthropometric parameters, axial triradii, digital triradii
Introduction: Obesity is associated with significant global morbidity and mortality. The prevalence of
obesity is on the rise, especially in low- and middle-income countries and there is a need for a tool for the
prevention of this disease As per the available pieces of evidence, dermatoglyphics can be utilized for this
purpose to some extent. Dermatoglyphics is a study of configurations of epidermal ridges on certain body
parts, namely, palms, fingers, soles, and toes.. The term is derived from ancient Greek: derma = skin, glyph
= carving. Dermatoglyphic patterns begin to develop in the 10th week of gestation and are complete by the
Aim: The primary objective of this study was to investigate the correlation of the “atd angle”(a dermatoglyphic
parameter) with the body fat distribution (or obesity).
Methods: This cross sectional study was conducted in the department of anatomy, Maharishi Markandeshwar
Institute of Medical Sciences and Research, Mullana (Ambala). It included 400 participants (200 males and
200 females) from students and employees of the college. All demographic and anthropometric parameters
along with the hand imprints were obtained using standard procedures. For determining statistical
significance of difference among various variables qualitative data was analyzed by Pearson’s Chi square
test and quantitative data by student’s independent t-test and one way ANOVA .P-value of < 0.05 was
considered significant. All analysis was done using SPSS version-20.
Results: Overall 24% of subjects (32% of males and 16% of females) were found to be obese (BMI?25kg/
m2).A statistically significant difference was observed in the values of both right and left hand“atd angle”for
the comparison of obese and non-obese subjects(p=0.009 and
<0.001,respectively). A statistically significant positive correlation of left hand “atd angle” was observed
Conclusion: Dermatoglyphics can potentially be used as a tool for the prediction of obesity.
Recommendations: A large-scale study with a well-defined protocol is required for establishing
dermatoglyphics as a screening tool for obesity.
