噪声与高温联合暴露对企业工人的健康影响

Objective To explore the health impacts of combined exposure to noise and high temperature on enterprise workers. Methods A total of 90 enterprise workers from March 2023 to March 2024 were selected as the research subjects. They were divided into three groups: the combined noise and high-temperature exposure group(30 cases), the simple noise exposure group(30 cases), and the control group(30 cases). The hearing loss conditions of the workers in different groups were compared, and the changes in their blood pressure and electrocardiogram were also clarified. Using multivariate Logistic regression analysis, the independent risk factors for occupational exposure-related diseases were identified. Results The speech-frequency hearing threshold and high-frequency hearing threshold in the combined exposure group were significantly higher than those in the single noise exposure group(P<0.05). The rates of hearing impairment, elevated blood pressure and electrocardiographic abnormalities in the combined exposure group were also significantly higher than those in the single noise exposure group and the control group(P<0.05). Multivariate Logistic regression analysis revealed that noise and high temperature were independent risk factors for hypertension. Conclusion Combined exposure to noise and high temperature can have adverse effects on the health of enterprise workers, and is associated with an increased risk of hearing impairment, hypertension and abnormal electrocard-iogram. Enterprises are recommended to strengthen health education and protective measures, optimize the working environment, and reduce the hazards induced by combined exposure to noise and high temperature.
