Air pollution and cognitive function: the potential protective effect of physical activity.

ABSTRACT: Physical activity (PA) may mitigate pollution-related cognitive decline while concurrently increasing individuals' exposure to harmful pollutants. Data were obtained from the 2018 China Health and Retirement Longitudinal Study (CHARLS), comprising 17,734 participants aged 45 years or older. Information regarding particulate matter (PM₁, PM_2.5, and PM₁₀), nitrogen dioxide (NO₂), sulfur dioxide (SO₂) and ozone (O₃) was sourced from the China High Air Pollutants (CHAP) database. The assessment of cognitive function was carried out following the approach utilized in the Health and Retirement Study (HRS). The impact of air pollutants on cognitive function was estimated using the two-stage least squares method, with the ventilatio
