This study investigated the hearing loss characteristics among occupational noise exposure workers with hypertension and the link between hypertension and hearing loss when exposed to occupational noise.
A total of 267,766 occupational noise-exposed workers were enrolled, including 29,868 workers with hypertension and 240,165 without hypertension. Hypertension was diagnosed according to WHO criteria. Hypertension was classified into four grades based on blood pressure. Assessment of hearing was performed through measurement of an unadulterated tone threshold at different frequencies, which ranged between 250 and 8,000 Hz.
A substantial link was observed to exist between hypertension and the increment in the hearing limit. The increase in the hearing threshold was substantially higher among those having grade 2 hypertension.
The current investigation suggested patients with hypertension exhibit a substantial rise in hearing loss in comparison with patients without hypertension. The rise in hearing loss was significant in patients with grade 2 hypertension. Efficient and practicable measures are required to decrease the hearing loss in workers with hypertension and work-related noise exposure.
本研究调查了高血压职业噪声暴露工人的听力损失特征，以及职业噪声暴露与高血压之间的听力损失关联。
共纳入 267766 名职业噪声暴露工人，其中 29868 名工人患有高血压，240165 名工人无高血压。高血压按照世界卫生组织（WHO）标准诊断。根据血压将高血压分为四级。通过测量 250 至 8000 Hz 不同频率的未受干扰的纯音阈值来评估听力。
高血压与听力阈移的增加之间存在显著关联。二级高血压患者的听力阈值增加幅度明显更高。
本研究表明，与无高血压的患者相比，高血压患者的听力损失显著增加。二级高血压患者的听力损失增加更为显著。需要采取有效且可行的措施，降低高血压和职业噪声暴露工人的听力损失。
