Relationship Between Occupational Exposure to Noise and Vibrations and Vertigo: A Prospective Case-Control Study
Abstract
Background/Objectives: It is known that balance disorders involve occupational hazards. However, the inverse relationship (between certain occupations and an increased incidence of vertigo or dizziness) has been scarcely studied. The objective of this work was to analyze the occupation of a group of patients with vertigo compared to the economically active general population and to evaluate the prevalence of occupational noise and/or vibration exposure in both groups. Methods: A prospective cross-sectional, observational, case-control study was carried out, including 393 patients (193: Meniere’s disease; 63: vestibular migraine; 21: vestibular neuritis; 116: BPPV) (244 women and 149 men). These patients were compared to a control group from the general population obtained from 6th EWCS-Spain (2015). Possible differences regarding sex, age, occupation, exposure to noise, and exposure to mechanical vibrations were analyzed. Results: Differences in the distribution of occupations between patients with vertigo and the general population were observed (Chi-square, p = 4.065 × e−20). Patients with vertigo were significantly more exposed to noise (Fisher’s exact test, p = 2.97 × e−10; OR = 2.595, CI95% (1.916;3.515)) and vibrations (Fisher’s exact test, p = 6.23 × e−10; OR = 2.722, CI95% (1.963;3.775)) than the control group. These differences were observed both between men and women. Conclusions: A relationship between occupational exposure to noise and/or vibrations and the…
How strong is the evidence?
Evidence Hub reads this as a case-control, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 393 participants or records.
