AB  - OBJECTIVE: The aims of this study were to analyze the hematological parameters, 
      the prevalence of anemia and the association between anemia and socioeconomic 
      conditions in an elderly community-based population. METHODS: A population-based 
      study was performed as part of the Multidimensional Study of the Elderly in Porto 
      Alegre, Brazil (EMIPOA). An initial total of 1058 community residents aged 60 
      years and older were interviewed. Of these, 392 agreed to have a physical 
      evaluation and a blood sample was taken from each. The hematological parameters 
      analyzed in the blood samples included the hemoglobin concentration, mean cell 
      volume (MCV), mean corpuscular hemoglobin concentration (MCHC) and red cell 
      distribution width (RDW). The association between the variables and the diagnosis 
      of anemia was assessed using the chi-squared test and a multiple logistic 
      regression model. RESULTS: The overall prevalence of anemia was 12.8%. Anemia was 
      present in 13.7% of women and in 10.4% of men. Normocytic normochromic anemia 
      without anisocytosis was the most common type of anemia (46%). The assessment of 
      erythrocyte morphology showed significant differences between anemic and 
      non-anemic individuals (microcytosis = 12% vs. 1.5%, hypochromia = 40% vs. 8.8%, 
      and anisocytosis = 26% vs. 7%). In the analysis of socioeconomic conditions, 
      significant differences were found in respect to age and race. CONCLUSION: The 
      prevalence of anemia increases with age and is associated with race, 
      microcytosis, hypochromia and anisocytosis. Anemia is not a condition that should 
      be associated only with the aging process, as it may be due to pathological 
      conditions that occur most frequently in this age group. As a result, a diagnosis 
      of anemia warrants adequate clinical attention.
