Abstract
Purpose. The principal goal of this investigation was to assess how obstructive sleep apnea affects hearing impairments in workers who are regularly exposed to occupational noise.
Materials and methods. In this investigation, we assessed 920 noise-exposure workers in one of the metal industries in Iran. Noise-induced, high-frequency, and low-frequency hearing loss were classified based on the mean hearing thresholds of more than 25 dB at 500–2000 Hz, 300–8000 Hz, and 4000 Hz, respectively. We used the STOP-Bang questionnaire for screening for sleep apnea, and a score of ≥3 indicated a high risk of obstructive sleep apnea. Multivariable logistic regression analyses were used to evaluate the correlation between hearing impairment and obstructive sleep apnea risk.
Results. The mean hearing thresholds at 3000–8000 Hz and specifically at 4000 Hz were significantly higher among workers at high risk for obstructive sleep apnea compared to those at low risk (p-value <0.05). Following the multivariate logistic regression analysis and the confounding factor adjustment, individuals with high obstructive sleep apnea risk showed a higher incidence of noise-induced hearing loss (p = 0.002, OR = 1.85, 95% CI = 1.28–2.36) and high-frequency hearing loss (p = 0.02, OR = 2.05, 95% CI = 1.28–2.16) compared to those with low risk.
Limitations. The cross-sectional design and use of a subjective screening method instead of objective methods such as polysomnography for evaluating obstructive sleep apnea are weaknesses of this study.
Conclusion. The current study showed obstructive sleep apnea in noise-exposed workers increased the risk of developing high-frequency hearing loss and hearing impairment from noise. So, identifying and managing workers with obstructive sleep apnea risk, early hearing screening, and periodic audiometry can help to prevent hearing loss in the primary stage.
