Abstract

Objectives: To examine the independent association between diabetes mellitus (and its duration and severity) and quadriceps strength, quadriceps power, and gait speed in a national population of older adults. Design: Cross‐sectional nationally representative survey. Setting: United States. Participants: Two thousand five hundred seventy‐three adults aged 50 and older in the N ational H ealth and N utrition E xamination S urvey 1999–2002 who had assessment of quadriceps strength. Methods: Diabetes mellitus was ascertained according to questionnaire. Measurement of isokinetic knee extensor (quadriceps) strength was performed at 60º/s. Gait speed was assessed using a 20‐foot walk test. Multiple linear regression analyses were used to assess the association between diabetes mellitus status and outcomes, adjusting for potential confounders or mediators. Results: Older U.S. adults with diabetes mellitus had significantly slower gait speed (0.96 ± 0.02 m/s) than those without (1.08 ± 0.01 m/s; P < .001). After adjusting for demographic characteristics, weight, and height, diabetes mellitus was also associated with significantly lower quadriceps strength (−4.6 ± 1.9 Nm; P = .02) and power (−4.9 ± 2.0 W; P = .02) and slower gait speed (−0.05 ± 0.02 m/s; P = .002). Associations remained significant after adjusting for physical activity and C‐reactive protein. After accounting for comorbidities (cardiovascular disease, peripheral neuropathy, amputation, cancer, arthritis, fracture, chronic obstructive pulmonary disease), diabetes mellitus was independently associated only with gait speed (−0.04 ± 0.02 m/s; P = .02). Diabetes mellitus duration in men and women was negatively associated with age‐adjusted quadriceps strength (−5.7 and −3.5 Nm/decade of diabetes mellitus, respectively) and power (−6.1 and −3.8 W/decade of diabetes mellitus, respectively) (all P ≤ .001, no significant interactions according to sex). Glycosylated hemoglobin was not associated with outcomes after accounting for body weight. Conclusion: Older U.S. adults with diabetes mellitus have lower quadriceps strength and quadriceps power that is related to the presence of comorbidities and walk slower than those without diabetes mellitus. Future studies should investigate the relationship between hyperglycemia and subsequent declines in leg muscle function.

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.
