Abstract WP374: Racial Disparities in Stroke Mortality in the United States 2000-2009
OBJECTIVES: To test the hypothesis that the racial disparities in stroke mortality have declined in the last decade due to increased awareness and recognition.
DESIGN: Analysis of the U.S. multiple-cause-of-death files for 2000 to 2009.
PARTICIPANTS: Decedents with stroke (defined by ICD-10 code I60-I64) as underlying cause of death on the death certificate.
MEASUREMENTS: Age-adjusted fatal stroke incidence for whites, African Americans, American Indians, and Asian and Pacific Islanders aged 25 and older based on the U.S. Census of 2000. The stroke rate ratio with 95% confidence interval (CI) and average annual percentage change over 10 years was also calculated.
RESULTS: From 2000-2009, the U.S. age-adjusted annual death rate per 100,000 for stroke was 242 in African Americans and 199 in whites. The difference between rates in African Americans and whites ranged from 2 excessive deaths per 100,000 in persons aged 25-34 years to 82 excessive deaths per 100,000 in persons aged 75-84 years. Compared with whites, the stroke rate ratio was 1.2(95% CI 1.0-1.3) for African Americans, 0.6(95% CI 0.5-0.8) for American Indians, and 0.8(95% CI 0.7-1.0) for Asian and Pacific Islanders. The average annual percentage change over 10 years was -6.1%, -5.3%, -5.2%, and -4.6% Asian and Pacific Islanders, American Indians, whites, and African Americans, respectively.
CONCLUSION: There has been a similar reduction in stroke related mortality among all racial groups between 2000 and 2009. However, the excessive stroke mortality among African Americans continues and is unlikely to change without primary and secondary preventive strategies targeted towards African Americans.
