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 (normal 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 2D∶3D, 2D∶4D, 2D∶5D, 3D∶4D, 3D∶5D, 4D∶5D between the control group and the patient group were compared. The correlation between 2D∶4D and onset age in the patient group were analyzed.   Results Except for left and right hand 3D∶4D, digit ratios in patient group were significantly higher than those in control group (2D∶4D and 3D∶5D in both hands, right hand 3D∶5D, p all<0.001; 2D∶3D and 4D∶5D, left hand 3D∶5D, P <0.01). Compared with the control group (left hand: 1%, right hand: 1%), the percentage of 2D∶4D ≥1 were significantly higher (P <0.05) in the patient group (left hand: 6%, right hand: 7%). There were no correlations between 2D∶4D mean value and onset age in patients group (P >0.05).  Conclusion Digit ratio is related to the occurrence of schizophrenia in Ningxia Han male.
