The aim of this study was to examine the influence of low hemoglobin (Hb) and anemia on mortality in the elderly in a ten-year follow-up (1997-2007). Among the 1,742 elderly participants in the baseline cohort from Bambu, Minas Gerais State, Brazil, 1,322 (82.3%) were followed for an average of 8.9 years. Probability of survival was estimated by Kaplan-Meier and Cox%26apos;s proportional hazard ratios (HR), and confidence intervals (95% CI) were used, considering potential confounders. Anemia and low Hb (lowest tertile) were associated with increased risk of death (HR = 2.63, 95% CI: 1.83-3.76 and HR = 1.38, 95% CI: 1.07-1.79, respectively). The results show that anemia or low Hb (regardless of a diagnosis of anemia) should be interpreted and managed as independent determinants of mortality in this elderly population.
