Correlation between the Degree of Hearing Loss and the Levels of Anxiety and Depression in Patients with Tinnitus

Objectives: This study aimed to explore the correlation between the degree of hearing loss (HL) and the degrees of anxiety and depression in patients with tinnitus. Materials and Methods: This retrospective study involved the use of basic clinical data from 600 enrolled patients with tinnitus who visited the otolaryngology clinic in Affiliated Jinhua Hospital, Zhejiang University School of Medicine from April 2020 to June 2022. The tinnitus handicap inventory (THI) scale was used to assess the tinnitus status among the participants. The pure tone audiometry (PTA) test was used to conduct audiological assessments for all patients to determine their hearing condition. The self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to assess the levels of anxiety and depression among the participants, respectively. The correlation between the HL and anxiety/depression scores from the questionnaires was tested through Pearson correlation analysis. Results: Among the 600 enrolled patients with tinnitus, most patients had mild-to-moderate degree of tinnitus, accounting for 248 cases (41.3%) and 179 cases (29.8%), respectively. PTA results showed that a large proportion of patients with tinnitus were accompanied with HL (467 cases, 77.8%). Among them, patients with mild HL accounted for the largest proportion with a total of 241 cases (40.2%). Based on the results of SAS and SDS test, almost half of the patients had symptoms of anxiety and depression, accounting for 52.3% (314 cases) and 48.8% (293 cases), respectively. Similarly, patients with mild anxiety and depression occupy the largest proportion, accounting for 35.8% (215 cases) and 23% (138 cases), respectively. Pearson correlation analysis showed that the degree of HL was closely related to THI/SAS/SDS scores (P < 0.001). Conclusion: These findings indicate a strong positive correlation between the degree of HL and anxiety/depression scores in patients with tinnitus
