Alcohol as a risk factor for hearing loss: A systematic review and meta-analysis

Abstract

Objective Growing evidence suggests that alcohol consumption is a risk factor for hearing loss; however, the evidence has been inconsistent. This systematic review and meta-analysis aimed to evaluate the effect of alcohol consumption on hearing loss. Methods We searched several databases up to November 2021, for published articles using the keywords “alcohol drinking” and “hearing loss”. Two investigators independently conducted the study selection and data extraction. Based on the results of the heterogeneity analysis (Q statistic and I2 statistic), a fixed- or random-effects model was used to calculate the pooled odds ratios (ORs). Subgroup and sensitivity analyses were performed to assess the potential sources of heterogeneity and robustness of the pooled estimation. Publication bias in the literature was evaluated using Egger’s test. Results In total, 18 (9 cross-sectional, 5 case-control, and 4 cohort) observational studies were identified in this search; 27,849 participants were included. Compared with non-drinkers, the pooled OR of drinkers was 1.22 (95% confidence interval: 1.09–1.35). Conclusion Evidence suggests a positive association between alcohol consumption and hearing loss. Drinkers were at a higher risk than non-drinkers. Drinking limitations may be useful for preventing hearing loss.

Impact of Nutrient-Stimulated Hormone (NUSH) Dynamics on Body Weight

“…A total of 10 meta-analysis studies were included in this study, which evaluated liraglutide, semaglutide, and tirzepatide for the treatment of obesity [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”

Scalp necrosis following preoperative endovascular embolisation of the superficial temporal artery for meningioma

“…The estimated blood loss for this case was 300 cc, as per literature similar cases that do not undergo embolisation have an estimated blood loss of 450 cc. In fact, a retrospective study demonstrated that the estimated blood loss was higher in the embolised group (410 vs 315 mL, p=0.0074)1 and can range up to 691.43 cc 10…”

Variations in the Cadherin 23 Gene Associated With Noise-Induced Hearing Loss

“… 22 , 23 One possible reason for this may be the stabilisation of sequencing or the methods used for establishing groups, which employed different ages, sex and smoking or drinking statuses. Qian et al 24 confirmed alcohol as a risk factor for hearing loss. Furthermore, in another study on the association between NIHL and gene analysis, the researchers found an association between NIHL and the rs41281334 of CDH23 , providing more evidence on the CDH23 gene and NIHL.…”
