A study of the prevalence of and risk factors for ear diseases and hearing loss in primary school children in Hat Yai, Thailand.
2,184 primary school children in Hat Yai Municipality, Southern Thailand were screened for ear diseases and hearing loss using screening audiometry, portable tympanometry and otoscopy to identify children with possible ear problems, 754 children failed the initial screen, 728 were retested and a group of 243 were referred for ENT examination and standard audiometry-tympanometry. Children with hearing loss and otitis media were thus identified. A questionnaire to identify possible risk factors was administered. The prevalence of otitis media in this population was found to be 3.25 per cent (AOM 0.69%, OME 1.14%, COM 1.74%). No risk factor identified as significant were found. Non-significant factors included sex, age, URI last month, father smoking, mother smoking and method of transport to school as an indication of social status. This study contrasts with a previous study in 1990 which showed a 3.5 per cent prevalence of COM.
