Abstract:
ObjectiveTo explore the relationship between the occupational noise exposure and arteriosclerosis in mechanical manufacturing workers. Methods A total of 453 employees of a machinery manufacturing enterprise were selected as the study subjects using the judgment sampling method. The noise exposure levels in their workplaces were measured, and their cumulative noise exposure (CNE) was assessed based on the type of job-noise exposure matrix and occupational hazard exposure history. Pure-tone audiometry was performed on the research subjects, and their brachial-ankle pulse wave velocity (baPWV) was measured. Results The CNE was (91±11) dB(A) per year and the median baPWV was 1 278.0 cm/s in the research subjects. The results of the generalized linear regression model analysis showed that for every one dB(A) per year increase in CNE, the baPWV of the general population increased by 0.20% ［95% confidence interval (CI) 0.10%-0.30%, P<0.01］, with an increase of 0.17% in males (95%CI 0.06%-0.28%, P<0.01) and 0.28% in females (95%CI 0.07%-0.49%, P<0.01). Using the hearing loss as an outcome indicator for high intensity noise exposure, the results showed that baPWV increased by 7.04% (95%CI 2.42%-11.87%, P<0.01) in individuals with bilateral hearing loss, and by 9.84% and 6.53% (95%CI 3.07%-17.07% and 2.13%-11.11%, all P<0.01) in individuals with elevated high-frequency hearing thresholds in both ears and in either ear, respectively. There was no significant association in elevated speech-frequency hearing thresholds and arteriosclerosis (P>0.05). Conclusion Occupational noise exposure may increase the risk of arteriosclerosis.
