Associations of long-term exposure to ambient PM_2.5 with mortality in Chinese adults: A pooled analysis of cohorts in the China-PAR project.

ABSTRACT:

Background

The concentration-response relationship between mortality and long-term exposure to fine particulate matter (PM_2.5) has not been fully elucidated, especially at high levels of PM_2.5 concentrations.

Objective

We aimed to evaluate chronic effects of ambient PM_2.5 exposure on deaths among Chinese adults in high-exposure settings.

Methods

Participants of the Prediction for Atherosclerotic cardiovascular disease Risk in China (China-PAR) project were included from four prospective cohorts among Chinese adults aged ≥18 years old. The overall follow-up rate of the four cohorts was 93.4% until the recent follow-up survey that ended in 2015. The average of satellite-based PM_2.5 concentrations during 2000-2015 at 1-km spati
