Serum Albumin Level and Activities of Daily Living in Centenarians Hiroyuki Nozaki1), Yumiko Nohara2), Ikuya Ashitomi2), Ryoko Zukeran2), Tetsuya Inafuku2), Masafumi Akisaka1) and Makoto Suzuki1) The relationship between serum albumin level and activities of daily living was studied in 95 centenarians. There were 73 women (12 rank J: free-living, 18 rank A: unable to go outside without help, 20 rank B: bedridden but able to sit on the bed, 23 rank C: completely bedridden) and 22 men (9 rank J, 7 rank A, 6 rank B or C). nificantly lower than that of rank J men. The A/G ratio or albumin fraction (%) measured by serum electrophoresis was similar to that of the serum albumin level of centenarians of both sexes. There were no significant differences in the serum protein level or in the peripheral hemoglobin level between rank J centenarians and those of other ranks, for both sexes. The serum albumin level is a valuable indicator of the ability to perform activities of daily living and may be a useful prognostic index in centenarians.
