Abstract

The transition from independence to disability in older adults is characterized by detectable changes in body composition and physical function. Epidemiologic studies have shown that weight loss, reduced caloric intake and the reduced intake of specific nutrients are associated with such changes. The mechanisms underlying these associations remain unclear, and different hypotheses have been suggested, including the reduction of the antioxidant effects of some nutrients. Changes in muscle mass and quality might play a central role in the pathway linking malnutrition, its biological and molecular consequences, and function. A different approach aims at assessing diets by dietary patterns, which capture intercorrelations of nutrients within a diet, rather than by selective foods or nutrients: epidemiologic evidence suggests that some types of diet, such as the Mediterranean diet, might prevent negative functional outcomes in older adults. However, despite a theoretical and empirical basis, intervention studies using nutritional supplementation have shown inconclusive results in preventing functional impairment and disability. The present work is the result of a review and consensus effort of a European task force on nutrition in the elderly, promoted by the International Association of Gerontology and Geriatrics (IAGG) European Region. After the critical review of different aspects related to the role of nutrition in the transition from independence to disability, we propose future lines for research, including the determination of levels of inadequacy and target doses of supplements, the study of interactions (between nutrients within a diet and with other lifestyle aspects), and the association with functional outcomes.

  • Many healthy older adults fail to eat enough dietary protein, and the situation is worsened when they are sick or disabled.

    “Many healthy older adults fail to eat enough dietary protein, but the situation is worsened when they are sick or disabled.”

    From Evidence-Based Recommendations for Optimal Dietary Protein Intake in Older People: A Position Paper From the PROT-AGE Study Group (2013) · cites this paper as [68]

    The sections on dietary adequacy and decreased food intake in older community-dwellers (page unavailable) report widespread nutritional inadequacy and say age-related appetite loss may predispose to protein undernutrition. They also identify acute and chronic disease as risk factors for malnutrition. They do not establish that many specifically healthy older adults eat too little protein, or that protein intake worsens when older adults become disabled. (LLM, conf=0.82)

  • When older adults have acute or chronic diseases, their activities are more limited, they are less likely to consume adequate food, and they fall farther behind in energy and protein intake.

    “When older adults have acute or chronic diseases, their activities are more limited, they are less likely to consume adequate food, and they fall farther behind in energy and protein intake.67,68”

    From Evidence-Based Recommendations for Optimal Dietary Protein Intake in Older People: A Position Paper From the PROT-AGE Study Group (2013) · cites this paper as [68]

    The 'Risk factors and pathophysiology of decreased food intake' section (page unavailable) identifies pain from acute or chronic disease as a risk factor for malnutrition. It also says loss of appetite in ageing may predispose to protein and energy undernutrition. It does not establish that disease itself limits activities or that affected older adults fall progressively farther behind in energy and protein intake; the decline in physical activity is attributed to ageing generally. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Malnourished older people recover from illness more slowly, have more complications, and are more frequently admitted to hospitals for longer stays than healthy older adults.

    “As a result, malnourished older people recover from illness more slowly, have more complications, and are more frequently admitted to hospitals for longer stays than are healthy older adults.67,68”

    From Evidence-Based Recommendations for Optimal Dietary Protein Intake in Older People: A Position Paper From the PROT-AGE Study Group (2013) · cites this paper as [68]

    The “Nutrition, physical performance, frailty and disability” section links undernutrition to frailty and functional limitations, but does not address recovery from illness, complications, or hospital admission and length of stay. Searches for those specific outcomes found no supporting passage in our copy; page numbers were not available. (LLM, conf=0.75)

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.
