To evaluate the prevalence of anemia among elderly people related to socioeconomic and health conditions in elderly attended by the Family Health Strategy (FHS) in the city of Porto Alegre-RS, Brazil.

We assessed 556 senior citizens. The prevalence of anemia, assessed by hemoglobin measurement was 8.8%, representing 10.1% for men and 8.1 % for women. A normochromic normocytic anemia was the type of anemia most commonly found (34.0%), suggesting chronic disease. Furthermore, the prevalence of normocytic and hypochromic anemia was 32.0%, suggesting an evolution of anemia by chronic disease in early stages of iron deficiency. Analyzing health and socioeconomic conditions, significant differences were found among age range, color, educational level, presence or absence of primary caregiver, hospitalization, thyroid disease, report of weakness and use of anti-anemic medications.


Low prevalence of anemia in the elderly in Porto Alegre-RS was observed. Numerous are the triggering factors of low hemoglobin levels. Factors such as age, color, family income, education, care, associated diseases are relevant to influence this event. Anemia should not be considered only associated with aging condition, but to many diseases that are common in this population and therefore deserves appropriate medical attention. Characterization of anemia should be carefully performed to aid its correct treatment.
