Abstract:

Recent literature has found compelling evidence of spatial heterogeneity in racial/ethnic Cardiovascular health (CVH) differences, which remain pervasive throughout the U.S. These geographically varying racial/ethnic CVH disparities may be attributed to residential segregation, since it may shape CVH through its impact on resources and opportunities for healthy behaviors including access to healthy foods, walkability, and recreational resources, in addition to the level of stressors which has been linked to adverse health outcomes that may affect CVH. However, more research is needed to confirm that residential segregation operates as a fundamental cause for CVH inequities. Our research examined whether residential segregation modifies racial/ethnic CVH differences while allowing for spatial heterogeneity in these inequities, using data from the Multi-Ethnic Study of Atherosclerosis (MESA). Utilizing Bayesian spatial methods, we assessed the spatial patterning of the impact of segregation on racial/ethnic CVH differences, while accounting for individual and neighborhood characteristics within each study site, with the goal to further understand this relationship.
