Objective:
The purpose of this study was to describe the factors related to dizziness in workers with noise-induced hearing loss in Brazil.
Method:
A cross-sectional study was carried out with a sample from noise-induced hearing loss reports (2007-2019). The dependent variable in this study was dizziness, and the independent variables were sociodemographic characteristics, comorbidities, symptoms, and noise characteristics in the work environment. Logistic regression analysis was performed.
Results:
A total of 3,824 individuals with noise-induced hearing loss in Brazil were analyzed. The prevalence of dizziness was 23.4% in the sample. Factors associated with dizziness were women (odds ratio [OR]: 2.10; 95% confidence interval [CI] [1.64, 2.69]), hypertension (OR: 1.68; 95% CI [1.38, 2.06]), headache (OR: 6.31; 95% CI [5.26, 7.57]), tinnitus (OR: 3.46; 95% CI [2.82, 4.25]), and continuous noise at the work environment (OR: 1.54; 95% CI [1.22, 1.94]).
Conclusions:
The factors associated with the outcome-dizziness-were gender (female), systemic arterial hypertension, headache, tinnitus, and continuous exposure to workplace noise. Such findings demonstrate the importance of promoting a multifactorial approach to understanding dizziness among workers exposed to occupational noise.
