Prevalence of Hearing Loss: Determining its Epidemiological Variants among the Omani Population

Undertaken in the Sultanate of Oman in 1996-97 was community based national survey for estimating the prevalence of hearing loss and determining its epidemiological variants among the Omani population. Another purpose of the survey was to enumerate the major causes of deafness. Trained investigators examined 11,400 members of the Omani population of all ages to detect hearing disabilities and common ear diseases. Findings: The investigators found that 55.3 persons per thousand of the population had some degree of deafness. Bilateral hearing loss was found in more males than in females. The rate of deafness increased with age and in the age group 60+ the prevalence rate was the highest (325 per 1000 population). The prevalence was lowest in the 0 to 9 years of age population––16.7 persons per 1000. Of the total persons surveyed, 20.68 per thousand had a disabling type of deafness. Of this type of hearing loss, the prevalence among males and females was nearly equal. The rate of disabling deafness increased with age. In the age group 60+, the prevalence rate was the highest (217.6 per 1000 population). It was as low as 5.9 per 1000 population in the age group of 0-9 years. Chronic suppurative otitis media, otitis media with effusion, and dry perforation of the tympanic membrane were the major causes of hearing loss in persons below 30 years age. Presbyacusis was the major causative agent in persons above 50 years of age.
