Living near major traffic roads and the incidence of dementia; Air Pollution and Children's Health, London Schools



From The Lancet - Living near major roads and the incidence of dementia, Parkinson's disease, and multiple sclerosis: a population-based cohort study


Findings

"Between 2001, and 2012, we identified 243 611 incident cases of dementia, 31 577 cases of Parkinson's disease, and 9247 cases of multiple sclerosis. The adjusted hazard ratio (HR) of incident dementia was 1·07 for people living less than 50 m from a major traffic road (95% CI 1·06–1·08), 1·04 (1·02–1·05) for 50–100 m, 1·02 (1·01–1·03) for 101–200 m, and 1·00 (0·99–1·01) for 201–300 m versus further than 300 m (p for trend=0·0349)".

Interpretation

"In this large population-based cohort, living close to heavy traffic was associated with a higher incidence of dementia, but not with Parkinson's disease or multiple sclerosis".

Dementia rates 'higher near busy roads', BBC News


Living near heavy traffic increases risk of dementia, say scientists, The Guardian -Study tracking 6.6 million people estimates one in 10 cases of Alzheimer’s among those living by busy roads could be linked to air and noise pollution


Is this the most polluted street in the UK? BBC
