Abstract

OBJECTIVES: To describe the accumulation of aging‐associated health disorders using a cumulative measure known as a frailty index (FI) and to evaluate its ability to differentiate long‐ and short‐life phenotypes as well as the FI's connection to aging‐associated processes in older people. DESIGN: Retrospective cross‐sectional and longitudinal studies. SETTING: The National Long‐Term Care Survey (NLTCS) data that assessed health and functioning of U.S. older individuals (≥65) in 1982, 1984, 1989, 1994, and 1999 were analyzed. The NLTCS sample in each survey represents a mixture of longitudinal and cross‐sectional components. PARTICIPANTS: Approximately 5,000 individuals in each survey. MEASUREMENTS: A cumulative index of health and well‐being deficiencies (disabilities, signs, diseases) was calculated as a count of deficits observed in an individual divided by the total number of all considered deficits. RESULTS: Men and women who died before the age of 75 and those who died after the age of 85 exhibited remarkably similar FI frequency patterns despite the 10‐year age difference between age profiles in these samples. Long life is consistently characterized in longitudinal analyses by lower FIs. FI dynamics are found to be strongly sex sensitive. CONCLUSION: The FI appears to be a sensitive age‐independent indicator of sex‐specific physiological decline in aging individuals and a sex‐specific discriminator of survival chances. The FI is a promising characteristic suitable for improving sex‐sensitive forecasts of risks of adverse health outcomes in older people.

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

  • The results yielded by the frailty index have been consistent between surveys evaluated by our group and by others even though not every frailty index considers the same deficits or number of deficits.

    “the results yielded by the frailty index have been consistent between surveys evaluated by our group [4-7] and by others [8-11] even though not every frailty index considers the same deficits, or even the same number of deficits.”

  • It does not matter if study A considered 40 deficits from set X and study B considered 60 deficits from set Y; the estimates from each (e.g. rate of deficit accumulation, relationship with mortality, limit) appear to be similar.

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.
