We found a positive relationship between occupational noise exposure ≥85 dBA at baseline and the 10-year incidence of hypertension. The findings were consistent with the results in a retrospective study that reported a signi ficantly higher risk of hypertension in sawmill workers exposed to ≥85 dBA for more than 30 years (10). Although their findings werelimited to a misclassi fication of noise exposure because of no adjustment for the use of hearing-protective devices at work,the 2 longitudinal studies reached similar results to show an increased risk of hypertension following long-term chronic occupational noise exposure. Moreover, the present study overcame the lack of individual risk factors of hypertension in the previous study (10) to provide strong evidence that hypertension was associated with ccupational noise exposure. We suggest that the currently regulated threshold for occupational noise exposure may expand the prevention ofnoise-induced hearing loss (41) to the risk of hypertension,which is a leading cause of cardiovascular diseases.
