Abstract

Adequate skeletal muscle strength is essential for physical functioning and low muscle strength is a predictor of physical limitations. Older adults with diabetes have a two- to threefold increased risk of physical disability. However, muscle strength has never been investigated with regard to diabetes in a population-based study. We evaluated grip and knee extensor strength and muscle mass in 485 older adults with diabetes and 2,133 without diabetes in the Health, Aging, and Body Composition study. Older adults with diabetes had greater arm and leg muscle mass than those without diabetes because they were bigger in body size. Despite this, muscle strength was lower in men with diabetes and not higher in women with diabetes than corresponding counterparts. Muscle quality, defined as muscle strength per unit regional muscle mass, was significantly lower in men and women with diabetes than those without diabetes in both upper and lower extremities. Furthermore, longer duration of diabetes (≥6 years) and poor glycemic control (HbA1c >8.0%) were associated with even poorer muscle quality. In conclusion, diabetes is associated with lower skeletal muscle strength and quality. These characteristics may contribute to the development of physical disability in older adults with diabetes.

  • Diabetes in the aging population is associated with reduced muscle strength, poor muscle quality, and accelerated loss of muscle mass, which may result in sarcopenia and/or osteopenia.

    “Diabetes in the aging population is associated with reduced muscle strength, poor muscle quality, and accelerated loss of muscle mass, which may result in sarcopenia and/or osteopenia (74,75).”

    From 13. Older Adults: <i>Standards of Care in Diabetes—2024</i> (2024) · cites this paper as [75]

    The Discussion (page unavailable) associates type 2 diabetes in community-dwelling older adults with lower muscle strength and quality. It does not establish accelerated loss of muscle mass: the study is cross-sectional and calls for prospective research on muscle-mass loss. The cited passages also do not link these findings to sarcopenia or osteopenia. (LLM, conf=0.91)

  • Diabetes in the aging population is associated with reduced muscle strength, poor muscle quality, and accelerated loss of muscle mass, which may result in sarcopenia or dynapenia and/or osteopenia.

    “Diabetes in the aging population is associated with reduced muscle strength, poor muscle quality, and accelerated loss of muscle mass, which may result in sarcopenia or dynapenia (76) and/or osteopenia (77,78).”

    From 13. Older Adults: Standards of Care in Diabetes—2025 (2025) · cites this paper as [78]

    The Abstract and Discussion report lower muscle strength and quality in older adults with type 2 diabetes. They do not establish accelerated muscle-mass loss or subsequent sarcopenia or dynapenia: the study found greater arm and leg muscle mass in participants with diabetes, and the Discussion says prospective research is needed to examine muscle-mass loss. Osteopenia is attached to different citations (77, 78), so it is not assessed against this source. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • People with diabetes of longer duration, and those with higher A1C, have lower muscle strength per unit of muscle mass than BMI- and age-matched people without diabetes, and than those whose disease is of shorter duration or under better glycemic control.

    “People with diabetes of longer duration, and those with higher A1C, have lower muscle strength per unit of muscle mass than BMI- and age-matched people without diabetes, and than those whose disease is of shorter duration or under better glycemic control90.”

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.
