Objectives The aim of this study was to examine the association between tinnitus and several potential risk factors in Korean population. Design A cross‐sectional study. Setting Based on data from the fifth Korean National Health and Nutrition Examination Survey. Participants The study included 10 061 Korean individuals. Main outcome measures Tinnitus was assessed by using a questionnaire, and otorhinolaryngologic examination was conducted. Risk factors associated with tinnitus were evaluated using a multiple logistic regression analysis. Results Of the 10 061 participants ranging from 20 to 97 years old, the overall prevalence of any tinnitus was 21.4% and annoying tinnitus was 7.3%. In a multivariable logistic regression model, the following factors were associated with having tinnitus: occupational noise exposure [any tinnitus, odd ratio (OR) = 1.34; annoying tinnitus, OR = 1.47], non‐occupational noise exposure (any tinnitus, OR = 1.48; annoying tinnitus, OR = 2.02), hearing impairment (any tinnitus, OR = 2.27; annoying tinnitus, OR = 3.61), chronic otitis media (any tinnitus, OR = 1.53; annoying tinnitus, OR = 1.36), chronic rhinosinusitis (any tinnitus, OR = 1.38; annoying tinnitus, OR = 1.38), temporomandibular disorder (any tinnitus, OR = 1.69; annoying tinnitus, OR = 1.90), depression (any tinnitus, OR = 1.44; annoying tinnitus, OR = 1.70), and higher stress level (any tinnitus, OR = 1.28; annoying tinnitus, OR = 1.76). Conclusions These results suggest that tinnitus is common in Korea and may be associated with some avoidable risk factors.
