Impact of noise exposure on workers' health in the petrochemical industry

Noise is one of the harmful physical factors in the workplace that affects the health of people exposed to it. This cross-sectional study was conducted on ۱۸۶ petrochemical industry workers in ۲۰۲۴. Then, the systolic and diastolic blood pressures of the subjects were measured, and blood samples were sent to the laboratory to determine the triglyceride and cholesterol levels. ISO ۱۵۶۶۶ questionnaires were used to assess noise annoyance. The mean heartbeat rate was significantly higher in the case group (۸۱.۷۹±۲.۸۳) than that in the control group (۷۷.۱۱±۹.۱۰), suggesting that exposure to loud noise can induce physiological stress and elevate heartbeat rates (p-value< ۰.۰۰۱). The results showed a significant difference between the systolic and diastolic blood pressures of the case group and the control group (P <۰.۰۰۵). Based on the results of this study, noise can be considered as one of the factors affecting the heart and blood vessels in exposed people. This study can also help inform the policies of the Ministry of Health regarding the supervision of periodic examinations of workers in industries in the control of cardiovascular diseases.
