Objectives:
Tinnitus and dizziness are common among the elderly. The conditions may increase depression, and patients may become susceptible to falls, thereby affecting the quality of life of the geriatric population. Investigating the prevalence of persistent tinnitus and chronic/recurrent dizziness in an elderly population and analyzing the association of certain comorbidities with tinnitus and dizziness in southern Taiwan were the main purposes of this study.
Materials And Methods:
This was a cross-sectional study performed in a metropolitan hospital. Hearing tests were conducted in a total of 597 volunteers aged ≥65 years involving 322 (53.9%) men and 275 (46.1%) women recruited in the study. The pure tone average (PTA) and hearing handicap (HH) score were calculated. Patients completed questionnaires regarding the history of hypertension and diabetes and symptoms of tinnitus and dizziness. The association of gender, age, PTA/HH, body mass index (BMI), hypertension, diabetes, and metabolic syndrome (MetS) with tinnitus and dizziness were analyzed.
Results:
The prevalence of persistent tinnitus and chronic/recurrent dizziness was 32.0% and 24.1%, respectively. Tinnitus or dizziness were not associated with age, BMI, hypertension, diabetes, and MetS but was associated with hearing impairment. Women and those with fasting glucose levels <100 mg/dL were more likely to experience dizziness.
Conclusion:
Persistent tinnitus and dizziness were common in an elderly population in southern Taiwan. These findings may help develop strategies to promote the quality of life in the elderly population.
