Abstract: Objective To analyze the occupational health examination results of noise-exposed workers in Suzhou,and to provide scientific basis for the supervision department to formulate noise prevention and control policies. Methods The occupational health examination data of noise workers in Suzhou in 2021 were collected,and the results of high-frequency hearing,blood pressure,hematuria routine,liver function and electrocardiogram were analyzed from 5 dimensions of gender,age,length of service,economic type and scale of enterprise. Results A total of 196 371 subjects were included in this study. The number and detection rate of high frequency hearing threshold loss,hypertension,elevated alanine aminotransferase and abnormal electrocardiogram were 15 044（7.66%）,47 370（24.12%）,28 054（14.29%） and 29 332（14.94%）. The detection rates of high frequency hearing loss,hypertension,abnormal white blood cell count,abnormal red blood cell count,abnormal hemoglobin count,urine glucose,and elevated alanine aminotransferase were higher in males than in females,and the differences were statistically significant（all P<0.05）. The detection rate of high-frequency hearing threshold loss,hypertension,urinary occult blood and urine sugar increased with the increase of age and working age（all P<0.05）. The detection rates of high-frequency hearing loss,hypertension,urinary occult blood,urinary protein,urine sugar,and abnormal electrocardiogram of workers in domestic-funded enterprises and micro-enterprises were higher than those in other types of enterprises,and the differences were statistically significant（all P<0.05）. Conclusion The regulatory authorities need to strengthen the hearing protection of male,older and long-serving noise workers,as well as the supervision of domestic-funded enterprises and small and micro enterprises.
