Associations of Earphone Use with Tinnitus and Anxiety/Depression.

Objective: This study aimed to investigate the association of earphone use with audiologic and psychologic factors.

Materials And Methods: Korea National Health and Nutrition Examination Survey 2010-2012 data were collected for participants aged ≥12 years old with earphone use ≥1 hour/day. They were matched to a control group for age, sex, income, and education level. The relationship between earphone use and the hearing thresholds of pure-tone audiometry, tinnitus, and psychologic factors such as depression and anxiety, and other quality of life variables was analyzed using multiple logistic regression tests with complex sampling.

Results: Among the participants, 22.9% (449/1955) of earphone users and 18.1% (355/1600) of control participants had tinnitus (P < 0.001). Earphone users showed 1.27-times higher odds for tinnitus (95% confidence interval [CI] = 1.09-1.50, P = 0.003). Moreover, 6.5% (128/1955) of earphone users and 5.0% (97/1600) of control participants had anxiety and depressive symptoms (P = 0.033). Earphone users showed 1.32-times higher odds for anxiety and depressive symptoms (95% CI = 1.14-1.52, P = 0.040). Nevertheless, the hearing thresholds were comparable between earphone users and control participants.

Conclusion: Earphone use was associated with tinnitus and anxiety or depressive symptoms.
