Abstract

Objective Both obesity and muscle impairment are increasingly prevalent among older persons and negatively affect health and physical functioning. However, the combined effect of coexisting obesity and muscle impairment on physical function decline has been little studied. We examined whether obese persons with low muscle strength experience significantly greater declines in walking speed and mobility than persons with only obesity or low muscle strength.Design Community-dwelling adults aged > or = 65 years (n = 930) living in the Chianti geographic area (Tuscany, Italy) were followed for 6 years in the population-based InCHIANTI study.Measurements On the basis of baseline measurements (1998-2000), obesity was defined as body mass index (BMI) > or = 30 kg/m(2) and low muscle strength as lowest sex-specific tertile of knee extensor strength. Walking speed and self-reported mobility disability (ability to walk 400 m or climb one flight of stairs) were assessed at baseline and at 3- and 6-year follow-up.Results At baseline, obese persons with low muscle strength had significantly lower walking speed compared with all other groups (P < or = 0.05). In longitudinal analyses, obese participants with low muscle strength had steeper decline in walking speed and high risk of developing new mobility disability over the 6-year follow-up compared with those without obesity or low muscle strength. After the age of 80, the differences between groups were substantially attenuated. The differences seen in walking speed across combination of low muscle strength and obesity groups were partly explained by 6-year changes in muscle strength, BMI and waist circumference.Conclusions Obesity combined with low muscle strength increases the risk of decline in walking speed and developing mobility disability, especially among persons < 80 years old.

  • In the InCHIANTI study, mobility disability trajectories and gait speed over 6 years were steepest in individuals with obesity defined by BMI and low muscle strength.

    From Sarcopenic obesity in older adults: aetiology, epidemiology and treatment strategies (2018) · cites this paper as [200]

    The Results (Change over time in walking speed) report the most prominent six-year decline in walking speed among participants aged 65–80 with obesity and low muscle strength. The Results (Risk of mobility disability) report a higher rate of new disability at six years, but do not describe disability trajectories as steepest; the walking-speed finding is also qualified by age.

  • Data from the InCHIANTI study noted rates of 3.2-8.7% using low knee extensor strength with either high BMI or waist circumference.

    From Sarcopenic obesity in older adults: aetiology, epidemiology and treatment strategies (2018) · cites this paper as [200]

    The Methods (Measurement of muscle strength; page not provided) define low strength using knee extensor strength, and the Results (Risk of mobility disability; page not provided) describe analyses using BMI or waist circumference to define obesity. The passages in our copy do not report the claimed 3.2–8.7% rates, so the numerical range is unsupported. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • In the InCHIANTI study, community-dwelling older adults with dynapenic obesity showed a steeper decline in walking speed and an increased risk of developing new mobility disability over 6-year follow-up compared to those without obesity or dynapenia.

    “In the Invecchiare in Chianti (InCHIANTI, aging in the Chianti area) study, community-dwelling older adults with dynapenic obesity showed a steeper decline in walking speed and an increased risk of developing new mobility disability over the 6-year follow-up compared to those without obesity or dynapenia (38).”
  • Sarcopenia and obesity can co-occur and are synergistically associated with worse functional decline and outcomes than either condition alone.

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.
