Abstract:
Objective To investigate the health status of workers exposed to noise in a brewery in Beijing and to analyze the relationship between hearing loss and blood pressure. Methods A total of 949 noise-exposed workers in a brewery who participated in occupational health examination were selected as the investigation subjects. A survey was conducted to investigate the pure tone hearing threshold and abnormal blood pressure of the workers with different characteristics, and to analyze the relationship between the two. Results Among the noise-exposed workers, the detection rates of hearing abnormality, hypertension, and increased systolic and diastolic blood pressure were 73.55%, 52.37%, 43.84% and 46.47%, respectively. The detection rates of hearing abnormality, indicators of hypertension, high frequency hearing threshold abnormality and increased binaural high frequency hearing threshold on average in males were higher than those in females (P < 0.05). Except that there was no statistically significant difference in weighted values of the better ear’s hearing thresholds among different working age groups (P> 0.05), the detection rates of other hearing abnormality, indicators of hypertension, speech frequency hearing threshold abnormality, high frequency hearing threshold abnormality，increased binaural high frequency hearing threshold on average and the weighted value of the better ear's hearing threshold all increased or had an increasing trend with the increase of age or working years (P< 0.05). The detection rates of hypertension in the groups with high frequency hearing threshold abnormality and increased binaural high frequency hearing threshold on average were higher than those in the normal group (P＜0.05). Conclusion The noise-exposed workers in the brewery have hearing impairment, which is related to the occurrence of hypertension. It is recommended to strengthen the publicity and education on noise protection and take protective measures to reduce the occurrence of occupational noise injury.
