Hearing Loss Characteristics of Workers with Hypertension Exposed to Occupational Noise: A Cross-Sectional Study of 270,033 Participants

الملخص EN

Objectives.

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.

Methods.

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.

Results.

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.

Conclusion.

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.
