Ambient PM_2.5, ozone and mortality in Chinese older adults: A nationwide cohort analysis (2005-2018).

ABSTRACT:

Background

Cohort evidence linking long-term survival with exposure to multiple air pollutants (e.g., fine particulate matter [PM_2.5] and ozone) was extensively sparse in low- and middle-income countries, especially among older adults. This study aimed to investigate potential associations of long-term exposures to PM_2.5 and ozone with all-cause mortality in Chinese older adults.

Methods

A dynamic nationwide prospective cohort comprising 20,352 adults aged ≥65 years were enrolled from the Chinese Longitudinal Healthy Longevity Study and followed up through 2005-2018. Participants' annual exposures to warm-season ozone and year-round PM_2.5 were assigned using satellite-derived spatiotemporal estimates. A directed acyclic graph (DAG) was develo
