Racial/ethnic disparities in PM_2.5-attributable cardiovascular mortality burden in the United States.

ABSTRACT: Average ambient fine particulate matter (PM_2.5) concentrations have decreased in the US in recent years, but the health benefits of this improvement among different racial/ethnic groups are unknown. We estimate the associations between long-term exposure to ambient PM_2.5 and cause-specific cardiovascular disease (CVD) mortality rate and assess the PM_2.5-attributable CVD deaths by race/ethnicity across 3,103 US counties during 2001-2016 (n = 595,776 county-months). A 1 µg m^-3 increase in PM_2.5 concentration was associated with increases of 7.16 (95% confidence interval (CI): 3.81, 10.51) CVD deaths per 1,000,000 Black people per month, significantly higher than the estimates for non-Hispanic white people (1.76 (95% CI: 1.37,
