Abstract

OBJECTIVES: To determine whether obesity concurrent with sarcopenia (low muscle mass) or dynapenia (low muscle strength) is associated with increased falls risk in middle-aged and older adults. METHODS: 5-year prospective cohort study including 674 community-dwelling volunteers (mean ± SD age 61.4 ± 7.0 years; 48% female). Sarcopenia and dynapenia were defined as lowest sex-specific tertiles for dual-energy X-ray (DXA)-assessed appendicular lean mass (adjusted for height and fat mass) or lower-limb strength, respectively. Obesity was defined as the highest tertiles of DXA-assessed total or trunk fat mass. Change in falls risk was calculated using the Physiological Profile Assessment (z-scores: 0-1 = mild increased risk; 1-2 = moderate increased risk; >2 = marked increased risk). RESULTS: Multivariable linear regression analyses revealed mild but significantly increased falls risk scores for dynapenic obesity (change in mean z-score compared to non-dynapenic, non-obese group: 0.33, 95% CI 0.06-0.59 [men] and 0.46, 95% CI 0.21-0.72 [women]) and dynapenia (0.25, 95% CI 0.05-0.46 [women only]). CONCLUSIONS: Dynapenic obesity, but not sarcopenic obesity, is predictive of increased falls risk score in middle-aged and older adults. In clinical settings, muscle function assessments may be useful for predicting falls risk in obese patients.

  • Risk of falling is highest in individuals with low muscle mass and/or strength with obesity defined by percentage of body fat.

    “risk of falling was highest in individuals with low muscle mass and/or strength with obesity as defined by percentage of body fat219”

    From Sarcopenic obesity in older adults: aetiology, epidemiology and treatment strategies (2018) · cites this paper as [219]

    The Discussion reports that obesity combined with low muscle strength, but not low muscle mass, predicted an increased falls-risk score over five years in community-dwelling middle-aged and older adults. The Operational definitions section defines obesity by high DXA-assessed total or trunk fat mass, not percentage body fat; the study measured a risk score rather than observed falls. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • In a 5-year prospective cohort study, individuals with dynapenic obesity (based on trunk fat mass) had an increased risk of falls, but those with sarcopenic obesity did not.

    “In contrast, a 5-year prospective cohort study that included 674 middle-aged and older adults reported an increased risk of falls in individuals with dynapenic obesity (based on trunk fat mass) but not in those with sarcopenic obesity (112).”

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.
