Topic: Risk, prevention and care in population studies

During a median follow-up of 12.8 years, 2219 incident dementias were recorded. Compared with participants without tinnitus, those with tinnitus had a 10% increased risk of dementia (hazard ratios [HR]: 1.10, 95% CI: 1.00-1.20). Among the participants with tinnitus, compared with those with the lowest tinnitus severity, those with slight and moderate or severe tinnitus had 23% (95%CI: 1.03-1.46) and 64% (95%CI: 1.35-2.00) increased risks of dementia, respectively. Furthermore, compared with participants without exposure to noise, those with exposure to noise for more than 5 years had a 12% increased risk of dementia (HR: 1.12, 95%CI: 1.00-1.26). In addition, the longer time the participants exposed to noise, the higher the odds of having tinnitus (P for linear trend <.001). Tinnitus, tinnitus severity and long-term noise exposure were associated with incident dementia, and long-term noise exposure were related to tinnitus. Tinnitus and noise exposure are public health issues vital for dementia prevention.

Key findings

Why it matters

In UK Biobank participants followed a median of 12.8 years, tinnitus was associated with a 10% higher risk of dementia, with higher risk for more severe tinnitus, and noise exposure over 5 years was associated with a 12% higher risk. These observational findings point to tinnitus and noise as public health targets for prevention but do not show that treating them prevents dementia.
