We assessed socioeconomic position and hearing loss in a Norwegian population of 17 593 men and women aged 30–54 years in 1984–1986 who were followed for 11 years. We used analysis of variance, logistic regression, and population-attributable fraction analyses to examine associations. Significant socioeconomic inequalities in hearing loss were found among men. Adjusted odds ratios for hearing loss were approximately 1.3 to 1.9 for semi- and unskilled manual workers compared with participants with high occupational class; the population-attributable fraction of the prevalence of hearing loss over the cutpoint in the high-frequency (3, 4, 6, and 8 kHz) range was 35%.
