Introduction: Evidence reports co-occurring risk factors between cardiovascular disease (CVD) and cancer and treatment-resultant cardiotoxicities amplifying CVD risks.

Hypothesis: Given demographic disparities in CVD and cancer outcomes, we illustrated race and ethnicity-specific distributions of cardiovascular health (CVH) and quantified the contributions of socioeconomic factors to racial disparities in CVH among those with prior cancer.

Methods: In the National Health Examination and Nutrition Survey 2011-2020, we identified 2628 adults aged ≥18 years with prior cancer. CVH was assessed based on the American Heart Association’s Life’s Essential 8 metrics. The Kitagawa-Blinder-Oaxaca decomposition quantified the magnitude of individual socioeconomic factors contributing to racial differences in CVH.

Results: Of the 2628 US adults with prior cancer (mean[SD] age, 63.4[13.8] years; 57% women), 6.0% identified as Hispanic or Latino, 1.6% as non-Hispanic (NH) Asian, 5.2% as NH Black or African American, 84.1% as NH White, and 3.1% as uncategorized or multiple categories. NH Asian had the highest Life’s Essential 8 score (out of 100, women: 66.0; male: 69.2) in contrast to the poorest CVH in NH Black women (59.0) and Hispanic men (57.7). Overall, diet, physical activity, and body mass index were suboptimal. Across race, NH Black had the poorest blood pressure (women: 52.6, men: 41.8) and sleep (women: 74.3, men: 70.2), whereas uncategorized or multiracial group had high tobacco exposure (women: 43.6; men: 53.2). NH White women had the worst lipids (62.4), whereas NH Asian women (65.2) and Hispanic men (69.0) had the lowest glycemic score. Differences were partly explained by deprivation and low education contributing to poorer CVH among Hispanic and NH Black, whereas lower US nativity contributed to better CVH in NH Asian.

Conclusions: CVH in US adults with prior cancer was suboptimal with significant racial disparities explained by socioeconomic factors.
