This meta-analysis evaluated the association between transportation noise and the risk of depression and dementia in Europe. The study found a pooled relative risk of 1.059 for depression and 1.045 for dementia per 10 dB L den increase in noise. The estimated annual burden includes 563,600 cases of depression and 28,200 cases of dementia.
Key findings
- Pooled relative risk for depression was 1.059 per 10 dB L den increase in noise.
- Pooled relative risk for dementia was 1.045 per 10 dB L den increase in noise.
- Estimated annual burden includes 563,600 cases of depression in Europe.
- Estimated annual burden includes 28,200 cases of dementia in Europe.
Why it matters
Understanding the impact of environmental factors like transportation noise on mental health is crucial for public health. This study highlights a significant burden of disease, suggesting that noise pollution may contribute to increased rates of depression and dementia.
