Digital Ratio and Academic Performances of College Students

Earlier studies have associated 2D:4D of Humans to several anatomical and physiological differences, capable of predicting medical conditions and behaviours such as sporting capabilities. There however evidences linking digital ratios particularly 2D:4D to academic performances of college students. This study therefore aimed at elucidating the associations between Digital Ratio and Academic Performances among College students. This study employed a descriptive-cross sectional anthropometric designs, where a total of 247 students gave their consents. Conventional Index Finger - Ring Finger ratio and Anatomical Index Finger-Ring Finger ratios were determined in students at different Academic levels. The average 2D:4D value showed that the index fingers (2D) is typically shorter in males (0.94 ± 0.01 - 0.96 ± 0.05) compared to females (0.95 ± 0.05 - 0.96 ± 0.06). The conventional 2D:4D ratios for left (r = 0.021) and right (r = 0.01) hands and Anatomical 2D : 4D ratios for left (r = -0.074) and right (r = -0.094) hands all have weak correlation with the Students Cumulative Grade Point Average. The study conclusively provided a baseline record on the use of bodily anthropometric measurements to determine different levels of Academic Performances among College students.
