The purpose of this study was to synthesize the results of previously published observational studies through meta-analysis to clarify the association between smoking and noise-induced hearing loss (NIHL). We searched several databases as of October 2019. Based on the results of heterogeneity analysis (Q statistic and I2 statistic), a fixed effect model (for no heterogeneity; Q test P > 0.1 and I2 ≤ 50%) or a random effects model (for heterogeneity) was used to calculate the pooled odds ratios (ORs). We explored the potential dose-response relationship between smoking and NIHL as well. In total, 27 studies involving 30,465 participants were included. Compared with non-smokers, the pooled OR of current smokers was 2.05 (95% Confidence interval (CI): 1.71–2.46), and of former smokers was 1.11 (95% CI: 1.05–1.18). We found a curve linear association between an increasing number of pack-years (packages/day × smoking years) and risk of NIHL. The dose-response meta-analysis suggested that when the number of pack-years was less than fifteen, the risk of NIHL was increasing, and the highest combined OR was 5.25 (95% CI: 2.30–11.96) for pack-years of fifteen. After fifteen pack-years, the pooled OR had a slow decline. Our study indicated that smoking is a risk factor for NIHL. Current smokers have a higher risk than former smokers, and there is a positive dose-response relationship between smoking and NIHL.

Background Hearing loss is one of the most prevalent worker health conditions worldwide. Although the effect of noise exposure on hearing is well researched, other workplace exposures may account for significant hearing loss. The aim of this review was to determine whether occupational hand–arm vibration exposure through use of power or pneumatic tools, independent of noise exposure, is associated with permanent hearing loss. Do workers suffer from hand–arm vibration–induced hearing loss? Methods Peer-reviewed articles published in English between 1981 and 2020 were identified through five online databases with five search keywords. Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, including online database search methodology, study selection, article exclusion, and assessment of potential study design confounders and biases, were followed. Results Database searches retrieved 697 articles. Fifteen articles that reported 17 studies met the criteria for review. All but two studies revealed statistically significant associations between occupational exposure to hand–arm vibration and hearing loss. The majority of the study results revealed associations between hand–arm vibration and hearing loss, independent of potential age and noise confounders. Conclusion Few studies have examined the association between occupational exposure to hand–arm vibration and hearing loss. Dose response data were limited as only one study measured vibration intensity and duration. Although the majority of studies identified statistically significant associations, causal relationships could not be determined. Further research using standardized and uniform measurement protocols is needed to confirm whether the association between occupational exposure to hand–arm vibration and permanent hearing loss is causal and the mechanism(s).

“…The older guinea pigs were two-fold more sensitive to vibration than younger animals [49]. The combination of noise and vibration during the use of hand-held vibrating tools increased the risk of hearing loss in industrial workers [6,52]. Increased oxidative stress and chronic inflammation are also associated with ageing [53], and age-related cochlear structural alterations and degeneration of sensory and neural cells also occurred [54] that resembles normal aging.…”

Diverse groups of ototoxic agents and gene mutation induce hearing disorders. Several studies showed that increased oxidative stress, inflammation, and glutamate are involved in the initiation and progression of hearing disorders. Therefore, reducing these biochemical defects before and after exposure to ototoxic agents may prevent and improve the management of hearing loss. Previous studies with a single agent have yielded variable benefits in hearing disorders. This review briefly presents evidence for the involvement of oxidative stress, inflammation, and glutamate in the initiation and progression of hearing disorders. It proposes a novel concept that simultaneous elevation of the levels of antioxidant enzymes, dietary and endogenous antioxidant compounds, and reduction in the levels of glutamate may be necessary for the optimal benefits in prevention and improved management of hearing disorders. Supplementation with micronutrients can elevate the levels of antioxidant compounds and reduce the levels of glutamate. However, increasing the levels of antioxidant enzymes is complex requiring an activation of the nuclear transcriptional factor-2 (Nrf2). This review briefly describes the regulation of activation of Nrf2, and proposes a micronutrient mixture that can simultaneously activate Nrf2, enhance the dietary and endogenous antioxidant compounds levels, and inhibit the release and toxicity of glutamate for prevention and improved management of hearing loss.

Risk of hearing loss among workers with vibration‐induced white fingers

Abstract: This study supports the hypothesis that VWF increases the risk of hearing loss among workers who use hand-held vibrating tools in a noisy environment.
