Abstract：Objective To understand the current status of hearing impairment among noise-exposed workers in paper industry in Quzhou City, and to provide a scientific basis for formulating effective prevention and control strategies. Methods Occupational health inspection case cards of noise-exposed workers in paper industry in Quzhou City from 2016 to 2019 were extracted from the Occupational Diseases and Occupational Health Information Monitoring Subsystem under the China Disease Prevention and Control Information System. The data included general information of enterprises and workers and hearing test results. χ2 test and logistics regression model were used to analyze the monitoring data. Results A total of 7,613 noise-exposed workers in paper industry in Quzhou during 2016-2019 received occupational health examinations. There were 410 (5.39%) workers with noise-induced hearing loss (NIHL), 1 (0.01%) worker with suspected occupational noise-induced deafness, and 41 (0.54%) workers with occupational contraindication. Univariate analysis displayed that the detection rates of NIHL showed an upward trend with the increase of age. The detection rate of NIHL was found to be the highest in the age group≥50 years (16.53%) as well as in the group with ≥8 service years (7.06%). The detection rate of NIHL was significantly higher in males than in females (6.34% vs. 2.14%). The detection rate of NIHL was the highest in small enterprises (7.27%), but the lowest in large enterprises (3.68%), with a statistically significant difference. Multivariate analysis revealed that gender, age and seniority were the factors influencing hearing impairment (P<0.05). Conclusion Paper industry in Quzhou City should strengthen the guidance of occupational health protection for small paper-making enterprises. Male, elder and long working age workers should be taken as key groups to enhance health monitoring and individual protection.
