Description
Summary:The primary aim of this study was to determine if self-reported occupational noise exposure was associated with Raynaud's phenomenon. In northern Sweden, a nested case-control study was performed on subjects reporting Raynaud's phenomenon (N=461), and controls (N=763) matched by age, sex and geographical location. The response rate to the exposure questionnaire was 79.2%. The study showed no statistically significant association between occupational noise exposure and reporting Raynaud's phenomenon (OR 1.10; 95% CI 0.83-1.46) in simple analyses. However, there was a trend towards increasing OR for Raynaud's phenomenon with increasing noise exposure, although not statistically significant. Also, there was a significant association between noise exposure and hearing loss (OR 2.76; 95% CI 2.00-3.81), and hearing loss was associated with reporting Raynaud's phenomenon (OR 1.52; 95% CI 1.03-2.23) in a multiple regression model. In conclusion, self-reported occupational noise exposure was not statistically significantly associated with Raynaud's phenomenon, but there was a dose-effect trend. In addition, the multiple model showed a robust association between hearing loss and Raynaud's phenomenon. These findings offer some support for a common pathophysiological background for Raynaud's phenomenon and hearing loss among noise-exposed workers, possibly through noise-induced vasoconstriction.
