Abstract

This retrospective cohort study compared blood pressure (BP) control (BP <140/90 mm Hg) and all-cause mortality between US- and foreign-born blacks. We used data from a clinical data warehouse of 41 868 patients with hypertension who received care in a New York City public healthcare system between 2004 and 2009, defining BP control as the last recorded BP measurement and mean BP control. Poisson regression demonstrated that Caribbean-born blacks had lower BP control for the last BP measurement compared with US- and West African-born blacks, respectively (49% vs 54% and 57%; P<.001). This pattern was similar for mean BP control. Caribbean- and West African-born blacks showed reduced hazard ratios of mortality (0.46 [95% CI, 0.42-0.50] and 0.28 [95% CI, 0.18-0.41], respectively) compared with US-born blacks, even after adjustment for BP. BP control rates and mortality were heterogeneous in this sample. Caribbean-born blacks showed worse control than US-born blacks. However, US-born blacks experienced increased hazard of mortality. This suggests the need to account for the variations within blacks in hypertension management.
