The National Institute of Occupational Safety and Health rates noise-induced hearing loss as one of the top 10 work-related problems, involving at least 11 million workers. 7'his retrospective study examines the differences between pure-tone hearing loss and race/ethnicity in 216 white and 70 non-white male metal fabricating workers.
Significant variables upon univariate analysis found to be associated with race/ethnicity were mean years of employment and proportion of time worked without hearing protection.
Among whites, the permanent threshold average for 1,2,3 and 4 kHz was 25. 99 dB, compared with 17.71 dB in non-whites (P<0.01).
Backwards stepwise regression indicated that race/ethnicity, after being adjusted for years of employment, was the major-effect variable.
The results of this study suggest that occupational noise exposure alone does not alone account for the racial hearing differences.
