| Abstract |
A cross-sectional study of the effects of smoking on hearing loss was conducted among 397 Japanese male workers at a metal factory during their periodical health checkup. Hearing acuity was measured at 4kHz using a pure-tone audiometer in a quiet room. Among the total subjects, 55 (13.9%) were identified as having hearing loss at 4kHz, and 151 (38.0%) were currently exposed to occupational noise. When adjusted for age and occupational noise exposure, odds ratios of hearing loss were 3.16 for past smokers and 3.39 for heavy smokers compared with never-smokers. The association between smoking and hearing loss seems to be masked by atherosclerotic factors. Results suggest that the concurrent impact of smoking and occupational noise exposure on hearing loss require further attention. |
