Design: We conducted a search of MEDLINE, PubMed, PsycINFO, and lists of relevant articles published during a five-year period in English. Databases were searched using Medical Subject Headings (MeSH) terms and other appropriate keywords related to marital status, race/ethnicity, and CVD risk factors and outcomes. Four reviewers independently screened titles and abstracts and abstracted data from full-text articles. Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed.

Results: The search yielded 4,577 titles, and 18 studies were included in this review. Studies showed mixed findings on the relationship between marital status, race/ethnicity, and CVD risk factors. With regard to CVD outcomes, most studies reported findings that suggest being married may serve as a protective factor across race/ethnic categories. 

Conclusion: Some cardiovascular risk factors and disease outcomes vary by the intersection of marital status and race/ethnicity. Differences in the relationship between marital status, race/ethnicity, and cardiovascular health need to be examined further in future research. These differences should be considered in the development of interventions aimed at addressing health disparities.
