Association between racial residential segregation and Black-White disparities in cardiovascular disease mortality
Authors' conclusion
Counties with increased Black-White residential segregation have higher rates of NH Black CVD mortality and larger Black-White disparities in CVD mortality.
Study context
- Population
- US counties with ≥5% Black populations; Non-Hispanic (NH) Black and NH White adults aged ≥25 years, 2014 to 2017
- Participants
- 1,286 counties
- Exposure
- Highest vs lowest tertile of Black-White residential segregation
- Outcome
- NH Black CVD mortality
Methodological detailscounty-level, 2,611,560 NH White and 408,429 NH Black cardiovascular disease (CVD) deaths
- County-level
- 2,611,560 NH White and 408,429 NH Black CVD deaths
