Digit ratio in men with schizophrenia / 解剖学报

ABSTRACT

Objective To investigate the relationship between digit ratio and schizophrenia in men from Ningxia Han nationality. Methods Using anthropometry, digital camera was used to obtain finger photographs of both hands of 216 male subjects (nonnal control; 116, schizophrenia patient; 100). The anatomical points were marked and the length of each finger of both hands were measured by computer image analysis software (Image-Pro Plus 6 . 0 ) . Differences of the mean digit ratio of left and right hand 2D3D, 2D4D, 2D5D, 3D4D, 3D5D, 4D5D between the control group and the patient group were compared. The correlation between 2D4D and onset age in the patient group were analyzed. Results Except for left and right hand 3D4D, digit ratios in patient group were significantly higher than those in control group (2D4D and 3D5D in both hands, right hand 3D5D, p all0. 05). Conclusion Digit ratio is related to the occurrence of schizophrenia in Ningxia Han male.
