An Anthropometric Investigation of IndexFinger Length Ratio toRing Finger (2d:4d) in Schizophrenic Men Living in Khorasan Razavi

Abstract

Introduction:Schizophrenia is a group of mental disorders that its main characteristics are failure to understand reality and inability to do daily tasks. Anthropometry, which is a type of biometrics, is a science that measures the dimensions and angles of body parts, as well as skin lines and fingerprints on living people. Perhaps knowledge about natural features of finger dimensions provides useful information in the field of medical anthropometry. Therefore, anthropometric properties of the fingers can be used to identify and develop research in this topic. And given that finger length, like brain development, is formed by a family of developmental genes. So, the objective was to find a link between brain violation and finger length.Method:This study was a case-control and cross-sectional sampling was done in the one-year. The index and ring finger lengths of both hands in 62 schizophrenic men and 72 healthy subjects who were not diagnosed and aged 18 to 65 years old living in Khorasan Razavi were measured by digital caliper.Result:Significant differences were observed between the average index finger lengths (2d:4d) in men’s right hand of healthy and schizophrenic subjects. Among other variables, significant differences weren’tobserved between healthy and patients. Conclusion:It may seem that the results above are used by methods for genetic studies of biometric changes in people with schizophrenia from the index finger length ratio to the right and left ring fingers for further studies to make an estimation and generation. It’s essential to spread the similar statistical research wider statistical societies.Declaration of Interest: None
