Abstract: By using the Occupational Disease Information monitoring System of Tianjin,the physical examination data of 2,906 noise-exposed workers in Binhai New Area from 2020 to 2023 were collected. The generalized estimating equations （GEE） were adopted to analyze the influencing factors of high-frequency hearing loss. Univariate analysis showed that there were statistically significant differences in the detection rate of high-frequency hearing loss among groups with different genders,lengths of service,enterprise types,serum alanine aminotransferase （ALT） levels,and red blood cell counts （P<0.05）. GEE analysis indicated that men,employees of private and small enterprises,those with a length of service of ≥10 years,those with elevated serum ALT,abnormal blood routine,abnormal electrocardiogram and elevated blood pressure had a higher risk of hearing loss （P<0.05）. Special attention should be paid to noise-exposed workers who are male,have longer working years in private and small enterprises,and have abnormal health conditions,and their hearing protection measures should be strengthened.

Key words: high-frequency hearing loss, occupational health surveillance, GEE
