Fine Particulate Matter Is Associated With Lower Executive Functioning in Middle-aged and Older Adults: Cardiometabolic Disease as a Mediator.

ABSTRACT:

Background

PM2.5 pollution is expected to worsen in many places due to climate change, as a result of hotter temperatures, less precipitation, and increases in wind speed. PM2.5 exposure has adverse effects on humans that may accelerate the aging process. Less is known about whether physical and mental health conditions mediate the relationship between PM2.5 exposure and aging-related cognitive and functional limitations.

Methods

Longitudinal data from the Midlife in the United States study (MIDUS 2: 2004-05; MIDUS 3: 2013-14) were used, with a sample of approximately 5 000 individuals aged 32-84. Based on individuals' residential addresses at each wave, we identified census tract-level PM2.5 exposure as defined by 5-year annual averages. Missing data were handled using mult
