Analyzing the results of occupational health examination for workers exposed to noise in a place from 2020 to 2022
Objective To analyze the occupational health examination data of workers exposed to noise,and to explore the damage of noise to the health of workers.Methods The workers exposed to noise who underwent at least one on-job occupational health examination in the same physical examination institution from 2020 to 2022 were selected as the observation objects.The data of on-job occupational health examination were continuously monitored and collected,and the hearing loss,blood pressure,electrocardiogram and other results were statistically analyzed.2 528 in 2020,2 281 in 2021 and 2 151 in 2022.Results The rate of high blood pressure increased from 9.9％in 2020 to 19.4％in 2022(x2=90.57,P＜0.01);the detection rate of abnormal electrocardiogram increased from 19.8％in 2020 to 26.4％in 2022(x2=29.11,P＜0.01);the detection rate of speech frequency threshold abnormality increased from 2.0％in 2020 to 9.9％in 2022(x2=136.32,P＜0.01);the detection rate of high-frequency threshold abnormality increased from 30.7％in 2020 to 33.6％in 2022(x2=5.02,P＜0.05);the detection rate of high blood pressure is higher in men than in women(x2=18.65,20.33,17.34,P＜0.05);the detection rate of electrocardiogram(ECG)abnormalities was higher in women than in men(x2=4.91,27.96,9.70,P＜0.05);with the increasing age of workers,the rate of high blood pressure and abnormal detection of ECG is increasing(x2=1 073.02,943.88,895.75,1 058.78,917.09,857.03,P＜0.05);the detection rate of hearing abnormalities was higher in men than in women;with workers'increased age and seniority of noise exposure,the detection rate of hearing abnormalities in workers is increasing(x2=20.38,37.02,17.55,330.75,239.94,101.52,P＜0.05).Conclusion Noise causes hearing impairment,high blood pressure,and abnormal changes of electrocardiogram increase with the age of workers and the length of service exposed to noise.Seriously affects the health of the workers.Occupational health monitoring and health education should be strengthened to effectively protect the health of workers.
