Abstract

BACKGROUND: A decline in muscle mass and muscle strength characterizes normal aging. As clinical and animal studies show a relationship between higher cytokine levels and low muscle mass, the aim of this study was to investigate whether markers of inflammation are associated with muscle mass and strength in well-functioning elderly persons. METHODS: We used baseline data (1997-1998) of the Health, Aging, and Body Composition (Health ABC) Study on 3075 black and white men and women aged 70-79 years. Midthigh muscle cross-sectional area (computed tomography), appendicular muscle mass (dual-energy x-ray absorptiometry), isokinetic knee extensor strength (KinCom), and isometric grip strength were measured. Plasma levels of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were assessed by enzyme-linked immunosorbent assay (ELISA). RESULTS: Higher cytokine levels were generally associated with lower muscle mass and lower muscle strength. The most consistent relationship across the gender and race groups was observed for IL-6 and grip strength: per SD increase in IL-6, grip strength was 1.1 to 2.4 kg lower (p <.05) after adjustment for age, clinic site, health status, medications, physical activity, smoking, height, and body fat. An overall measure of elevated cytokine level was created by combining the levels of IL-6 and TNF-alpha. With the exception of white men, elderly persons having high levels of IL-6 (>1.80 pg/ml) as well as high levels of TNF-alpha (>3.20 pg/ml) had a smaller muscle area, less appendicular muscle mass, a lower knee extensor strength, and a lower grip strength compared to those with low levels of both cytokines. CONCLUSIONS: Higher plasma concentrations of IL-6 and TNF-alpha are associated with lower muscle mass and lower muscle strength in well-functioning older men and women. Higher cytokine levels, as often observed in healthy older persons, may contribute to the loss of muscle mass and strength that accompanies aging.

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

  • Higher levels of inflammatory markers in blood are associated with greater loss of muscle mass and strength, accelerated loss of mobility, lower-extremity performance and physical activity, and depression in older individuals.

    From Imaging of Sarcopenia in Type 2 Diabetes Mellitus (2024) · cites this paper as [20]

  • Altered adipose tissue growth and function lead to fluctuations in adipokines and cytokines, causing chronic inflammation, mitochondrial impairment, disruption of insulin signaling in skeletal muscle, and eventual muscular atrophy.

    “Altered adipose tissue growth and function lead to fluctuations in the concentrations of adipokines and cytokines, causing chronic inflammation, mitochondrial impairment, disruption of the insulin signaling pathway in the skeletal muscle, and eventual muscular atrophy.”

    From Imaging of Sarcopenia in Type 2 Diabetes Mellitus (2024) · cites this paper as [20]

  • Sarcopenia is contributed to by reductions in circulating sex hormones, physical inactivity, low-grade inflammation, impairments to neuromuscular junctions, and reduced satellite cell number and function.

    “Other factors that are known to contribute to sarcopenia include reductions in circulating sex hormones [8], physical inactivity [9], low grade inflammation [10,11], impairments to neuromuscular junctions [12], and reduced muscle stem cell (i.e., satellite cell) number and function [13].”
  • Circulating growth factors GDF11 and myostatin, as well as inflammatory markers TNF-α and IL-6, increase with age, impairing regenerative capacity of satellite cells in human skeletal muscle.

    “For instance, circulating growth factors, such as GDF11 and myostatin, as well as inflammatory markers, such as TNF-α and IL-6, increase with age, impairing the regenerative capacity of satellite cells in human skeletal muscle [10,115].”

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.
