| Resumen |
The effectiveness of hearing conservation programmes in preventing occupational noise-induced hearing loss was examined in a group of Canadian lumber mill workers, using annual audiogram series obtained from the Workers' Compensation Board of British Columbia for the period 1979-1996 and subjecting the data to Cox proportional hazard models. Mean cumulative noise exposure was 98.1 dB-years. The audiograms from 22,376 individuals, among whom there were 2,839 threshold shifts of 10 dB or greater were retained in multivariable analyses. After adjusting for potential confounders, continuous use of hearing protection, and initial hearing tests later in the study period, the risk of a 10-dB threshold shift was reduced by 30%. Risk remained high, however, among those with the highest noise exposure. |
