Dermatoglyphic Patterns in Undergraduate Medical Students and their Association with Academic Performance: A Cross-sectional Study

Abstract

Introduction: Dermatoglyphics is the study of fingerprint patterns, which are unique to each individual and remain unchanged after birth. It has been used in criminology for decades. In recent years, its role in screening various medical conditions has been established. Dermatoglyphics has also been associated with cognitive ability, making it a potential predictor of academic potential. Aim: To investigate the association between dermatoglyphic patterns and the academic performance of medical students. Materials and Methods: A cross-sectional study was conducted in the Department of Anatomy, Jawaharlal Nehru Medical College, Wardha, Maharashtra, India on 200 undergraduate medical students (94 males and 106 females) from January 2019 to December 2020. Fingerprint patterns were obtained using the standard ink method. The parameters studied included arches, loops, whorls, composites, Total Finger Ridge Count (TFRC), and the 'atd' angle. The academic performance of participants was assessed based on the marks obtained in the National Eligibility Cum Entrance Test (NEET) and the overall marks scored in the first-year university examination. Statistical analysis involved the use of arithmetic mean, standard deviation, Chi-square test, and one-way Analysis of Variance (ANOVA). Results: In present study, the most common fingerprint pattern in the right hand was an arch (30.9%), followed by a whorl (24.5%). In the left hand, the most common fingerprint pattern was a whorl (40.6%), followed by an ulnar loop (20.1%), with no gender difference observed. Thumb, index finger, middle finger, ring finger, and little finger exhibited different fingerprint patterns between the right and left hand, indicating asymmetry. This asymmetry was associated with lower academic performance. Higher academic performers in the NEET had a higher frequency of whorls and composites. TFRC showed no association with academic performance. Students with an ‘atd’ angle between 41 and 50° demonstrated higher academic performance. Conclusion: The present study found that asymmetry of fingerprint patterns and a higher ‘atd’ angle (≥51°) were correlated with lower academic performance among medical students. These findings suggest potential directions for early academic intervention, provided multicentric studies are conducted in the future.
