Abstract:
Objective To investigate the epidemiological characteristics of occupational noise induced deafness (ONID) in Nantong area and analyze the risk factors. Methods A total of 421 workers in hydropower industry who underwent physical examination in the outpatient clinic of Nantong Center for Disease Control and Prevention from January 2017 to December 2021 were selected as the research subjects.168 workers without ONID were divided into control group, and 253 workers diagnosed with ONID were divided into ONID group. The expression levels of serum cortisol, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in the two groups were compared and analyzed. Results There were more males than females in both groups (P<0.05). With the increase of working age, the detection rate of ONID also increased significantly (P<0.05). The hearing thresholds of left and right ears in workers of different workplaces in the ONID group were higher than those in the control group (P<0.05), and the hearing thresholds of workers in water wheel room and water machine operation duty room were higher (P<0.05). The expression levels of cortisol, IL-6 and TNF-α in the serum of ONID patients were significantly higher than those in the control group. Multivariate analysis showed that workplace, serum cortisol, IL-6 and TNF-α were the main influencing factors for ONID. Conclusion Workplace, serum cortisol, IL-6 and TNF-α are all risk factors for ONID. Appropriate measures should be taken to strengthen the prevention and treatment of noise-induced hearing loss according to the influencing factors.
