Résumé
Little is known about the role of air pollution in how people with dementia use mental health services. We examined longitudinal associations between air pollution exposure and mental health service use in people with dementia. In 5024 people aged 65 years or older with dementia in South London, high resolution estimates of nitrogen dioxide (NO In the first year of follow-up, increased exposure to all air pollutants was associated with an increase in the use of CMHTs in a dose-response manner. These associations were strongest when we compared the highest air pollution quartile (quartile 4: Q4) with the lowest quartile (Q1) (eg, NO Residential air pollution exposure is associated with increased CMHT usage among people with dementia. Efforts to reduce pollutant exposures in urban settings might reduce the use of mental health services in people with dementia, freeing up resources in already considerably stretched psychiatric services.
