Abstract

This review defines water-loss and salt-loss dehydration. For older people serum osmolality appears the most appropriate gold standard for diagnosis of water-loss dehydration, but clear signs of early dehydration have not been developed. In older adults, lower muscle mass, reduced kidney function, physical and cognitive disabilities, blunted thirst, and polypharmacy all increase dehydration risk. Cross-sectional studies suggest a water-loss dehydration prevalence of 20-30% in this population. Water-loss dehydration is associated with higher mortality, morbidity and disability in older people, but evidence is still needed that this relationship is causal. There are a variety of ways we may be able to help older people reduce their risk of dehydration by recognising that they are not drinking enough, and being helped to drink more. Strategies to increase fluid intake in residential care homes include identifying and overcoming individual and institutional barriers to drinking, such as being worried about not reaching the toilet in time, physical inability to make or to reach drinks, and reduced social drinking and drinking pleasure. Research needs are discussed, some of which will be addressed by the FP7-funded NU-AGE (New dietary strategies addressing the specific needs of elderly population for a healthy ageing in Europe) trial.

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?

  • In older adults, renal function is often poor so that renal parameters no longer accurately signal low-intake dehydration.

    “In older adults, renal function is often poor so that renal parameters no longer accurately signal low-intake dehydration (7,225,226).”

    From ESPEN practical guideline: Clinical nutrition and hydration in geriatrics (2022) · cites this paper as [7]

    Section 6 says kidney function declines with age and that reduced urine-concentrating ability may make urinary markers of dehydration less useful in older people. The claim overstates this tentative conclusion as renal parameters no longer accurately signaling low-intake dehydration; the passage does not establish that broader, definitive claim. (LLM, conf=0.86)

  • Older persons are at increased risk of dehydration for various reasons, and dehydration is related to serious health consequences.

    “Besides malnutrition, older persons are at increased risk of dehydration for various reasons, which is also related to serious health consequences (7,8).”

  • Memory problems may cause older adults to forget to drink and forget that they haven't drunk.

    “Memory problems may cause older adults to forget to drink and forget that they haven't drunk (7)(8)(9)252).”

    From ESPEN practical guideline: Clinical nutrition and hydration in geriatrics (2022) · cites this paper as [7]

  • The causes of low-intake dehydration in older adults are varied and inter-related.

    “The causes of low-intake dehydration in older adults appear to be varied and inter-related and have been examined in several non-systematic reviews (7,8,242).”

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.
