| Research Abstract |
In this study, we showed that hearing worsens with age, and this was especially obvious in males.
Our results suggested that vascular sclerosis and osteoporosisare risk factors associated with age related hearing impairment. High pulse wave velocity, a parameter of vascular sclerosis, was related to loss of hearing and decreasing of bone mineral density in females also caused hearing impairment.
We confirmed 13 GJB2 gene mutations in this study and also found that 39 of 597 participants (6.53%) were bearers of mutations known to cause hearing impairment.
