Abstract:
Hearing screening is well established in most developed countries, and the data extensively published. However, little information has been presented by the developing, nonwhite populations. A screening study was carried out on 2202 Jamaican children aged 5 to 7 years. This involved tympanometry and pure-tone audiometry (frequencies of 0.5, 1, and 2 kHz.) Failure was considered to have occurred if a type B or C curve was obtained or if the threshold of hearing was greater than 20 dB. These children were further evaluated by a full ear, nose, and throat examination, inclusive of pneumatic otoscopy, and audiologic testing. The prevalence of hearing impairment was 4.9%. Otitis media with effusion (OME) was present in 1.9%. The prevalence of OME in Jamaica is low when compared with that of the same age-group in the developed countries.
