Introduction: Anthropometry is a method that be used in medicine and industry by measuring the dimensions of the human body in different populations. The 2D:4D digit ratio can be a biomarker related to some diseases in people. In some of studies have reported a significant difference between 2D:4D in sick and healthy groups. Deafness is the most common sensory defect in human societies. The aim of the present study is to easily use the measurable characteristics of the hand for the early recognition of deafness.
Methods: In this observational analytical study, 120 genetically deaf girls and 200 healthy girls aged 7 to 11 in 4 age groups living in Mashhad city were investigated. The length of index and ring fingers on the inner surface of both hands was measured by digital calipers and the 2D and 4D growth pattern and 2D:4D ratio in healthy and deaf girls between left and right hands were processed with Excel and SPSS software.
Results: The evaluation of the 2D and 4D finger growth pattern in healthy and deaf girls showed the presence of symmetry in these two groups (except for the age group of 8-9 years), also the 2D:4D ratio in the left hand of healthy people compared to the left hand of deaf people in the group The age of 9-10 years and in the right hand of healthy people compared to the right hand of deaf people in the age groups of 7-8 years and 8-9 years showed a significant difference in the error level of 0.05.
Conclusion: It seems that by extending similar studies, anthropometric body measurements can be used as appropriate pre-knowledge in identifying the identity of related disorders. |
