Popis: Background: Black persons are an heterogenous group in the US and bear a disparate higher burden of worse cardiovascular disease (CVD) outcomes. Our objective was to examine ethnic differences in CVD mortality among Black subgroups; African Americans(AAs); African Immigrants(AIs); and Afro Caribbeans(ACs). Methods: We analyzed the 1999-2018 National Health Interview Survey data, prospectively linked to mortality records in the National Death Index on 23,169,679 Black adults. The outcomes was CVD mortality, defined as CVD and cerebrovascular deaths, which was modelled as time till death (in years). This was calculated from each survey year till time of death or December 31, 2019 (administrative censoring) for those who survived. Using multivariable Cox proportional hazards regression analyses to model the survival function, we evaluated differences in CVD-and cerebrovascular-cause specific deaths among the three groups with progressive adjustment for age, sex, socioeconomic status and CVD risk factors. Results: With median of 10 years of mortality follow-up, there were 2.44, and 1.86 CVD deaths per 1,000 person-years among AA, and foreign born black adults (AIs and ACs combined), respectively. CVD mortality hazard was 81% lower in AIs [hazard ratio [HR], 0.19 (95% CI, 0.13–0.29], Table ) and 54% lower in ACs [HR, 0.46 (95% CI, 0.40–0.53], than among AAs. Compared to AAs, age-and sex-adjusted CVD mortality hazard was lower among AIs by 66% [HR, 0.34 (95% CI, 0.23–0.51], Table ) and ACs (HR, 0.46 [95% CI, 0.40–0.53]) by 54% (unchanged from unadjusted). In the fully adjusted model with SES and CVD risk factors adjustment, ACs had 41% lower adjusted CVD mortality hazard than AA adults (HR, 0.59 [95% CI, 0.45–0.77]). Conclusions: Cardiovascular deaths were higher among US-born AAs than foreign-born ACs. Nativity status is an important determinant of CVD mortality, and the heterogeneity of this population should be considered in health disparities research and interventions.
