Impact of long-term exposure to PM_2.5 and its components on the risk of chronic lung disease in middle-aged and elderly chinese: evidence from a large Chinese population-based cohort.

ABSTRACT:

Background

Epidemiological evidence indicates a close association between particulate matter with an aerodynamic diameter of fewer than 2.5 μm (PM_2.5) and the occurrence and worsening of chronic lung diseases (CLD), particularly in middle-aged and older adults. Previous studies have explored the effects of PM_2.5 and its components on CLD to a limited extent, and the dynamic trajectories of PM_2.5 and its components over time have not been considered in relation to CLD.

Methods

This study used data from the China Health and Retirement Longitudinal Study (CHARLS) from 2011 to 2018 to explore the relationship between long-term exposure to PM_2.5 and its components (sulfate, nitrate, ammonium, organic matter, and black carbon) and CLD ba
