title: Factors associated with hearing loss among workers of the airline industry in Korea.
abstract: Noise-induced hearing loss (NIHL) is a major occupational hazard. Occupational noise exposure threatens the hearing of many workers. In addition to noise exposure in the workplace, multiple factors affect individual susceptibility to NIHL. The purpose of this study was to identify factors associated with hearing loss in airport workers. A cross-sectional epidemiological design was used. Study subjects were 255 high noise-exposed full-time male workers at a large metropolitan airport in Korea. Data were collected by a self-administered questionnaire, blood pressure measurement, audiological assessment, and a record review of baseline hearing and noise levels of locations where the employee worked. The result of multivariate analysis showed that both occupational noise exposure (noise exposure level, years of noise exposure) and personal risk factors including non-occupational noise exposure, history of ear disease, ototoxic drug use, cigarette smoking, hypertension, and use of hearing protective devices (HPDs) were significantly associated with hearing loss. An aggressive hearing conservation program is needed at the airport, emphasizing both job-related noise exposure and personal risk factors for hearing loss.
