Abstract: Objective To understand the differences in various indicators of occupational health examination results among noise-exposed workers in Tianjin. Methods Noise-exposed workers who underwent occupational health examinations at Tianjin Occupational Disease Precaution and Therapeutic Hospital from January to December 2023 were selected as research subjects. SPSS 27.0 software was used to analyze the basic information of the workers and the examination results of blood pressure,electrocardiogram,and pure tone audiometry. Results A total of 23 100 noise-exposed workers were included in the study. Among them,3 840 cases（16.62%） were identified with hypertension,3 284 cases（14.22%） had abnormal ECG results,and 7 043 cases（30.49%） exhibited high-frequency hearing threshold loss. There were statistically significant difference in the detection rate of various abnormal results among workers of different genders,ages,and working years（all P<0.05）. Furthermore,stratified individuals with high-frequency hearing loss,compared the prevalence of hypertension and ECG abnormalities among different levels,and the differences were statistically significant（both P<0.05）. Conclusion There are significant differences in the incidence of hypertension and electrocardiographic abnormalities among noise-exposed workers stratified by gender,age,length of service,and hearing loss. There is a correlation between occupational noise exposure and high-frequency hearing threshold loss,elevated blood pressure,and electrocardiographic abnormalities. In the high-frequency hearing loss frequency band of 4 000 Hz hearing level stratification,it is an independent influencing factor for hypertension and abnormal electrocardiogram.
