Stroke Mortality in Blacks

Abstract

Background —Despite long-term declines in US stroke mortality rates, declines have slowed in the past decade and targets for blacks for the years 2000 and 2010 seem attainable only by extraordinary measures, if at all. This review focuses attention on key aspects of this problem. Data from the US National Center for Health Statistics and reports of population-based studies of stroke mortality published since 1987 retrieved by computerized literature searches were reviewed. Summary of Review —The third leading cause of death in black women and the sixth in black men in the United States in 1996, stroke accounted for 10 509 deaths in women and 7972 in men among blacks: 7.92% and 5.33%, respectively, of the total deaths. Age-adjusted death rates per 100 000 were black women, 39.2; white women, 22.9; black men, 50.9; and white men, 26.3. Available data indicate that compared with US whites, US blacks have greater mortality rates for every stroke subtype, with the likely exception of cerebral infarction due to extracranial carotid artery occlusion. These differences will persist into the 21st century. The number of stroke deaths in blacks increased by >8% between 1992 and 1996. Conclusions —Increased research on stroke in blacks is needed to develop more effective strategies for primary and secondary prevention of stroke to reduce the high burden of premature mortality and morbidity. Renewed efforts to prevent and control stroke risk factors (in particular elevated blood pressure, diabetes, and smoking) are needed among US blacks.
