A recent study published in JAMA Network Open investigated how long-term exposure to air pollution influences the dynamic process of physical disability with aging. Long-term residential exposure to PM2.5, PM10-2.5, and NO2 was associated with a higher risk of worsening disability states, and PM2.5 was also associated with a lower likelihood of recovery from physical function limitations in older adults.

Understanding Air Pollution’s Role in Physical Disability
Life expectancy has increased worldwide, resulting in an expanded period of managing physical disabilities, which has significantly increased emotional and financial burdens. Older adults with physical disabilities require much more medical care and experience higher health care costs than those without. Considering these burdens, it is imperative to identify modifiable factors that influence physical disability in older adults, which could play a critical role in reducing or delaying disability.
