Background/Objectives:
Tinnitus is a significant global health concern with substantial geographic variation in prevalence. However, data on tinnitus epidemiology in southern Saudi Arabia remain limited, despite emerging evidence suggesting a relatively high regional burden. Therefore, this study aimed to estimate the prevalence of tinnitus and identify its epidemiological determinants among adults in southern Saudi Arabia.
Methods:
A community-based cross-sectional study was conducted among 501 adults from four regions in southern Saudi Arabia (Jazan, Aseer, Najran, and Al-Baha). Data were collected on sociodemographic characteristics, chronic medical conditions, noise exposure patterns, and clinical features of tinnitus. Multivariable logistic regression analysis was used to identify factors independently associated with tinnitus.
Results:
The overall tinnitus prevalence was 31.1% (156/501). The mean age of participants was 30 ± 11 years, and 61.7% were female. Bilateral tinnitus was the most common (47.4%). Symptom duration was reported as <3 months in 31.4% of cases and between 3 months and 1 year in another 31.4%. The mean severity score was 3.7 ± 1.9. Most affected individuals (76.9%) did not seek medical care. Primary exacerbating factors included sleep deprivation (41.7%), noise exposure (41.0%), and stress (39.1%). Multivariable analysis identified two significant independent predictors: weekly noise exposure exceeding 5 h (odds ratio [OR] = 2.14; 95% confidence interval [CI]: 1.34-3.42; p = 0.001) and higher body mass index (BMI) (OR = 1.06; 95% CI: 1.02-1.10; p = 0.005). The most commonly associated underlying conditions were ear infections (25.6%) and hearing loss (24.4%).
Conclusions:
Tinnitus prevalence in southern Saudi Arabia (31.1%) substantially exceeds global estimates. Noise exposure and elevated BMI are key modifiable factors associated with tinnitus. The substantial healthcare gap, with most affected individuals not seeking treatment, represents a critical public health challenge requiring targeted prevention programs, provider education, and improved access to evidence-based care.
