Abstract

Most epidemiologic data are related to the prevalence of anemia, and there is little information regarding the incidence or etiology of newly diagnosed anemia in older people. The purpose of this study was to define the incidence and characteristics of anemia in the elderly population of Korea. Three hundred thirty-two independent, community-living, elderly persons aged 60 years and older were enrolled, and laboratory tests including iron profiles were performed. The mean age was 72 ± 4.8 years and the mean hemoglobin was 13.4 ± 1.1 g/dl. During the follow-up period of 3 years, 24 subjects (3 males and 21 females) were newly diagnosed with anemia, which led to a 3-year incidence of 7.2% (24/332). Among the 24 subjects with new-onset anemia, iron deficiency anemia (IDA) was diagnosed in 5 subjects, while anemia of chronic disease (ACD) was detected in 8 subjects. Underlying illnesses were diabetes mellitus, osteoarthritis, renal insufficiency, hypothyroidism and malignancy. In those subjects with new-onset anemia, the serum iron, ferritin, transferrin saturation and albumin were lower than in the normal group. In conclusion, the 3-year incidence of anemia among Korean elderly people was determined to be 7.2%, and ACD was the most commonly defined cause of anemia.
