摘要

Objective

Exposure to noise elevates stress hormones and alters metabolism, raising cholesterol and triglyceride levels, thereby increasing cardiovascular risk. This study investigates the link between occupational noise, blood pressure, and lipid profiles in wood industry workers.

Methods

This cross-sectional study involved 249 male employees with at least one year of full-time employment in the wood industry. Participants were categorized into two groups: 166 workers exposed to noise levels exceeding 85 decibels (dB) (case) and 83 workers exposed to lower noise levels (control). Personal data, blood pressure measurements, and lipid profiles were obtained from existing medical records, and ambient noise levels were measured using a TES 1358C sound level meter.

Results

The findings indicated that workers in the case group, had significantly higher levels of TGC and LDL compared to those in the control group.The mean triglyceride levels were 330.55 mg/dL in the case group and 275.40 mg/dL in the control group, and mean LDL levels were 194.87 mg/dL and 155.42 mg/dL, respectively. Both TGC and LDL levels in both groups were notably higher than the standard clinical ranges. In the case group, positive significant correlations were observed between TGC and LDL, TGC and SBP, and LDL and SBP. The multiple linear regression analysis indicated that noise (β = 0.421, p = 0.014), age (β = 0.349, p = 0.001), work experience (β = 0.384, p = 0.004), and BMI (β = 0.230, p = 0.032) as a independent variables accounted for 27.5% of the variability in TGC in the case group.

Conclusion

This study indicates a heightened risk of metabolic and cardiovascular disorders within this population. Therefore, implementing effective safety measures to mitigate noise exposure in such work environments is crucial.
