Associations of exposure to PM_2.5 and its compounds with carotid intima-media thickness among middle-aged adults.

ABSTRACT:

Background

Exposure to fine particulate matter (PM_2.5) has been linked to an increased risk of atherosclerosis. However, it remains unclear whether specific compounds within PM_2.5, rather than the overall mass, serve as a better indicator of adverse cardiovascular health outcomes associated with air pollution.

Methods

In this cross-sectional study, we included 3257 participants (aged 37-51 years) from the Coronary Artery Risk Development in Young Adults (CARDIA) study. Exposure to PM_2.5 and its constituent compounds, black carbon (BC), ammonium, nitrate, organic matter, sulfate, mineral dust, and sea salt were included in the analyses. Carotid intima media thickness (cIMT; the average of common, bulb, and internal carotid) was measured by car
