Abstract

BACKGROUND: Adults with type 2 diabetes mellitus often have limitations in mobility that increase with age. An intensive lifestyle intervention that produces weight loss and improves fitness could slow the loss of mobility in such patients. METHODS: We randomly assigned 5145 overweight or obese adults between the ages of 45 and 74 years with type 2 diabetes to either an intensive lifestyle intervention or a diabetes support-and-education program; 5016 participants contributed data. We used hidden Markov models to characterize disability states and mixed-effects ordinal logistic regression to estimate the probability of functional decline. The primary outcome was self-reported limitation in mobility, with annual assessments for 4 years. RESULTS: At year 4, among 2514 adults in the lifestyle-intervention group, 517 (20.6%) had severe disability and 969 (38.5%) had good mobility; the numbers among 2502 participants in the support group were 656 (26.2%) and 798 (31.9%), respectively. The lifestyle-intervention group had a relative reduction of 48% in the risk of loss of mobility, as compared with the support group (odds ratio, 0.52; 95% confidence interval, 0.44 to 0.63; P<0.001). Both weight loss and improved fitness (as assessed on treadmill testing) were significant mediators of this effect (P<0.001 for both variables). Adverse events that were related to the lifestyle intervention included a slightly higher frequency of musculoskeletal symptoms at year 1. CONCLUSIONS: Weight loss and improved fitness slowed the decline in mobility in overweight adults with type 2 diabetes.

  • Both aerobic and resistance exercise have beneficial effects in people with type 2 diabetes, and combining them has additive benefits.

    “As is the case for persons with T2D, studies have demonstrated beneficial effects of both aerobic and resistance exercise and additive benefits when both forms of exercise are combined.727,847–852”

    From American Association of Clinical Endocrinology Clinical Practice Guideline: Developing a Diabetes Mellitus Comprehensive Care Plan-2022 Update. (2022) · cites this paper as [727]

    The Discussion (page not available) reports improved fitness and reduced mobility-related disability in adults with type 2 diabetes following a lifestyle intervention. It does not distinguish aerobic from resistance exercise or report additive benefits from combining them; the combination discussed there is weight loss plus exercise. (LLM, conf=0.78)

  • Physical activity is a key part of lifestyle treatment.

    “Increased physical activity is an important component of lifestyle therapy.674,727”
  • Longer maintenance of weight loss might further reduce the risk of type 2 diabetes in at-risk people and preserve gains in sleep apnea, physical mobility, and other conditions improved by weight loss.

    “Sustaining weight loss for longer periods may further improve the prevention of type 2 diabetes in at-risk individuals,34 as well as maintain improvements in sleep apnea,5 physical mobility,6 and other health conditions ameliorated by weight loss.7–9”
  • Physical activity and aerobic exercise guidelines are similar in people with type 2 diabetes independent of lean versus overweight or obese BMI.

    “Physical activity and aerobic exercise guidelines are similar in persons with T2D independent of lean vs overweight/obese BMI.431,674,727,728”

    From American Association of Clinical Endocrinology Clinical Practice Guideline: Developing a Diabetes Mellitus Comprehensive Care Plan-2022 Update. (2022) · cites this paper as [727]

    The Methods (Study participants; page not provided) include only overweight or obese adults with type 2 diabetes. The Methods (Study Design; page not provided) give this trial’s physical-activity goal, but do not compare exercise guidelines for lean and overweight or obese people. Searches for BMI-independent guidelines found no passage addressing that comparison. (LLM, conf=0.77)

    Experimental — accuracy not yet measured
  • In children, type 2 diabetes pathogenesis is critically driven by loss of β-cell function, and residual β-cell function determines glucose control in those recently diagnosed.

    “The pathogenesis of the syndrome in children is also critically determined by β-cell function loss with the degree of residual β-cell function determining glucose control in recently diagnosed patients160.”

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.
