Anemia is more common among older Blacks than in older Whites. However, it is unclear whether anemia predicts adverse events similarly in both races. Data on 1,018 black and 1,583 white adults aged 71-82 years were analyzed. Anemia, as defined by World Health Organization (WHO) criteria, was used to predict mortality over 6 years and incidence of mobility disability over 4 years. In proportional hazards models of mortality in Whites, the age-adjusted hazard ratio (HR) for anemia in men was 1.96 [95% confidence interval (CI): 1.35, 2.83] and in women was 2.86 (95% CI: 1.69, 4.82). In contrast, anemia was not associated with mortality in black men [HR=1.15 (95% CI: 0.77, 1.72)] or women [HR=1.39 (95% CI: 0.91, 2.14)]. Higher mortality rate was only observed in black men with hemoglobin values >2.0 g/dL below the WHO cutoff, whereas mortality rates were elevated in white men with hemoglobin values 0.1-1.0, 1.1-2.0, and >2.0 g/dL below the WHO cutoff. In conclusion, anemia was significantly associated with increased risk of death and mobility disability in community dwelling older Whites. Conversely, older Blacks classified as anemic by WHO criteria were not at risk for adverse events, indicating that alternative criteria are warranted.
