Objectives: To investigate the levels of vitamin A, E,
B 12, folic acid in employees with hearing loss due
Patients and Methods: Employees in a local hydroelectric
powerhouse who suffer from hearing loss due
to noise were included in the study. Study and control
groups were composed of 28 (mean age 37±5) and 30
voluntary subjects (mean age 36±4), respectively. All of
the subjects in patient and control groups were male.
Blood samples were obtained from all subjects and vitamin
A, E, B12 and folic acid levels were measured.
Results: Level of vitamin B12 was found low in
patient group and normal in control group and these
were found statisticaly significant (p<0.005). There
were no significant differences between vitamin A, E
and folic acid.
Conclusion: We think that measurement of vitamin
B12 in routine control of the people who are working
in noisy environment may be useful.
