One hundred senior citizens aged 80 years and over in homes for the aged were evaluated for the incidence of anemia (hemoglobin under 11.0g/dl), Hb concentration, serum iron, and total iron binding capasity (TIBC). The subjects were classified into different groups according to age distribution (80-84, 85-89, over 90), as well as sex and life activity levels. In the 80-84 year age group, the Hb concentration was 0.5g/dl higher than that in the other age groups. The Hb values of the male subjects were 1g/dl higher than the corresponding values for female subjects. Subjects classified as bedridden had Hb values 1.2g/dl lower than those in the groups that had higher activity levels (p<0.001). The incidence of anemia was independent of sex and age differences; however, differences in activity levels were significant (p<0.001). There are 53 patients with some diseases, urinary truct infections, bed sores (over 3cm diameter), chronic bronchitis, progressive cancers and chronic rheumatoid arthritis, which may be origins of anemia. Seventy six percent of bedridden patients have one or two of the above diseases and 30% of non-bedridden patients have these diseases. The difference was statistically significant (p<0.001). In the bedridden group, the differences of the mean Hb levels and the rates of anemia in patients with and without disease were not statistically significant (p>0.1 in both factors). These facts indicate that the bedridden elderly have a high risk of anemia which is independent of some infectious and malignant diseases.
