||This study investigated the relationship between self-assessed hearing problems and occupational exposure to solvents in 3284 men aged 53-74 years. Exposure to solvents for five years or more resulted in an adjusted relative risk (RR) for hearing impairment of 1.4 (95% CI: 1.1-1.9) in men without occupational exposure to noise. The prevalence of hearing impairment in men not exposed to organic solvents was 24 per cent and the attributable risk from solvent exposure was 9.6 per cent. Exposure for less than five years had no effect on hearing capacity. Occupational exposure to noise for five years or more had an effect twice that of solvents. RR: 1.9 (95% CI: 1.7-2.1). In men exposed to both solvents and noise the effect of the latter dominated and no additional effect from solvents was found. Damaging effect on hearing ability from long-term solvent exposure was found in the present study. The relative effect was moderate but with a high background frequency of hearing problems in the unexposed sample the absolute effect, i.e. attributable risk, was considerable and of both clinical and preventive importance.
