Air pollution increases the likelihood of people becoming frail in middle and old age, according to an international review of studies. Importantly, frailty is not inevitable; it can be delayed, prevented, or even reversed.”The review team found 10 studies that looked at outdoor air pollution and frailty. Two of the studies showed that men were more vulnerable than woman, with a stronger association between particle pollution and frailty. For the UK, this could mean about 10-20% of frailty cases are attributable to air pollution. In 2023 a government advisory committee found evidence that air pollution was adding to the burden of dementia.
