Social determinants of health (SDoH), health care use, and cardiovascular disease (CVD) risk perception are understudied among men who identify as Black and Hispanic. In this study we sought to describe these factors among a cohort of urban-residing Black men, participants in a community-engaged trial on hypertension prevention. We focused on presenting intermediary SDoH, including material circumstances, health behaviors, and psychosocial factors, which allow for a more robust understanding of health inequities but are underexplored. We analyzed baseline trial data (N=430) and compared subgroups (44% of participants self-identified as having Hispanic ethnicity and a Black racial identity). Average age was 38 years, with mean blood pressure of 129/83 mmHg. Hispanic Black (HB) men reported higher unemployment (21.4% versus 11.1%, P=.02) and more housing instability (28.7% versus 18.6%, P=.01) than did non-Hispanic Black (NHB) men. Overall, HB men reported worse household conditions compared with NHB men. Approximately half of both groups reported high stress, 45% (HB) and 51% (NHB), respectively. Both groups had low perception of personal CVD risk and underutilized health care. Hispanic Black men were less likely to have a primary care provider than were NHB men (17.6% versus 29.3%, P<.001). Non-Hispanic Black men reported lower physical activity than did HB men (median, 2655 vs 2547 metabolic equivalent minutes/week, P=.03). Recognizing heterogeneity among Black populations, including in social drivers of CVD disparities, will allow for more precision in designing CVD health promotion interventions. Findings also suggest that perception of personal CVD risk and health care utilization may be important targets for CVD prevention in Black men.
