Ambient fine particulate matter air pollution and the risk of hospitalization among COVID-19 positive individuals: Cohort study.

ABSTRACT:

Background

Ecologic analyses suggest that living in areas with higher levels of ambient fine particulate matter air pollution (PM_2.5) is associated with higher risk of adverse COVID-19 outcomes. Studies accounting for individual-level health characteristics are lacking.

Methods

We leveraged the breadth and depth of the US Department of Veterans Affairs national healthcare databases and built a national cohort of 169,102 COVID-19 positive United States Veterans, enrolled between March 2, 2020 and January 31, 2021, and followed them through February 15, 2021. Annual average 2018 PM_2.5 exposure, at an approximately 1 km² resolution, was linked with residential street address at the year prior to COVID-19 positive test. COVID-19 hospitalization w
