Abstract

While lower serum albumin concentration is often found in the elderly, a relation between serum albumin and age has not been fully elucidated. We conducted population-based cross-sectional and 5-y longitudinal study to examine the relation. A total of 22,705 male and 40,149 female, aged 65 y and older, living in Gifu, participated in the health check service conducted by Gifu City Medical Association. They were self-supported in the activity of daily living and 3,438 of them were followed up every year from 1999 to 2003. Serum albumin levels decreased with age in both men and women. In the cross-sectional study, median value declined from 4.3 g/dL in males aged 65-69 y to 3.9 g/dL in 90< or = y, and 4.3 g/dL to 4.0 g/dL in females. Incidence of hypoalbuminemia (serum albumin < or =3.5 g/dL) increased in parallel with age from 1.2% (65-69 y) to 6.6% (85-89) in males, and 0.6% to 4.1% in females. In the longitudinal study, regression analysis showed a significant decline in serum albumin of 0.015 g/dL per year (r= -0.716) in males, and 0.012 g/ dL per year (r= -0.794) in females. Relative reduction of serum albumin in 5 y was larger in advanced age; 1.2% in females aged 65-69 y and 3.1% in 85-89 y (p<0.05), but not in males. In conclusion, a fall in serum albumin concentration in community-dwelling, self-supported elderly persons was associated significantly with aging.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Serum albumin levels decrease with age, possibly increasing amyloid-β deposition in the brain, as albumin is able to sequester amyloid-β from the blood.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
