Abstract

BACKGROUND: Physical activity (PA) is considered beneficial for lowering cardiovascular risks following type 2 diabetes mellitus (T2DM) and prediabetes, but existing evidence relies mainly on self-reported measurements. We aimed to describe the intensity-specific dose-response associations of PA and sedentary behavior (SB) with macrovascular and microvascular events among individuals with T2DM and prediabetes. METHODS: This study included 11,474 individuals with T2DM and prediabetes from the UK Biobank. PA, including total PA, moderate-to-vigorous intensity PA (MVPA), light-intensity PA (LPA), and SB, were measured by accelerometers over 7 days. MVPA was categorized according to the American Diabetes Association guideline-recommended level (at least 150 min/week), and total PA, LPA, and SB were grouped by tertiles. The outcomes were incidences of macrovascular events, microvascular events, heart failure (HF), and their combination (composite events). The events were ascertained using the International Classification of Diseases-10 (ICD-10) codes on the hospital or death records. RESULTS: During a median follow-up of 6.8 years, 1680 cases were documented, including 969 macrovascular events, 839 microvascular events, and 284 incidents of HF. Accelerometer-measured PA, irrespective of intensity, was inversely associated with the risk of composite events and each outcome in the dose-response patterns. Regarding categorized PA, engagement in total PA (high vs. low) was associated with decreased risk of macrovascular events (hazard ratio (HR) = 0.80; 95% confidence interval (95%CI): 0.67-0.95), microvascular events (HR = 0.76; 95%CI: 0.63-0.93), and HF (HR = 0.46; 95%CI: 0.32-0.66). Adherence to MVPA, but not LPA, above the guideline-recommended level (at least 150 min/week) was associated with reduced risk of macrovascular events (HR = 0.80; 95%CI: 0.68-0.95), microvascular events (HR = 0.76; 95%CI: 0.63-0.92), and HF (HR = 0.65; 95%CI: 0.46-0.92). The minimum dose of MVPA for lowering the risk of composite events was approximately 59.0 min/week. More time spent in SB was associated with an increased risk of composite events (high vs. low, HR = 1.17; 95%CI: 1.02-1.35) and HF (high vs. low, HR = 1.54; 95%CI: 1.09-2.20). Replacement of 30 min of SB (HR = 0.73; 95%CI: 0.65-0.81) and LPA (HR = 0.74; 95%CI: 0.66-0.83) with MVPA dramatically reduced the risk of composite events. CONCLUSION: Adherence to a higher amount of accelerometer-measured PA, especially MVPA at least 59 min/week, is associated with reduced risks of macrovascular and microvascular events among individuals with T2DM and prediabetes. Replacement of SB and LPA with MVPA helped lower the risk of diabetic vascular events.

TL;DR

In UK Biobank adults with type 2 diabetes or prediabetes, accelerometer-measured moderate-to-vigorous physical activity (MVPA) showed inverse, generally non-linear dose-response associations with incident macrovascular and microvascular events, while light-intensity physical activity (LPA) had minimal benefit and sedentary behavior (SB) was associated with higher risk. The minimum MVPA dose associated with lower composite vascular event risk was about 59 min/week, below the guideline-recommended 150 min/week, with larger benefit at higher doses.

Key findings

  • Among 11,474 participants with T2DM/prediabetes, over a median 6.8 years, 1680 cases occurred: 969 macrovascular events, 839 microvascular events, and 284 heart failure (HF) cases.
  • For composite events, MVPA showed a non-linear inverse association: minimum dose 59.0 min/week; optimal dose 188.6 min/week, corresponding to HR 0.61 (95%CI 0.52–0.72). Meeting guideline MVPA (≥150 min/week) was associated with lower composite event risk (recommended vs. not recommended: HR 0.79, 95%CI 0.69–0.89).
  • High total PA was associated with lower composite event risk (high vs. low: HR 0.75, 95%CI 0.66–0.86), but high LPA was not (high vs. low: HR 0.96, 95%CI 0.84–1.09). High SB was associated with higher composite event risk (high vs. low: HR 1.17, 95%CI 1.02–1.35).
  • In isotemporal substitution, replacing 30 min/day of SB with MVPA reduced composite event risk (HR 0.73, 95%CI 0.65–0.81), and replacing 30 min/day of LPA with MVPA also reduced risk (HR 0.74, 95%CI 0.66–0.83).

Methods

  • Prospective cohort study using UK Biobank data; participants wore an Axivity AX3 wrist-worn triaxial accelerometer on the dominant wrist for 7 consecutive days. The analytic sample included 11,474 participants with T2DM or prediabetes and no prevalent diabetic vascular events.
  • Exposures were accelerometer-measured total PA volume, MVPA, LPA, and SB. Outcomes were incident macrovascular events, microvascular events, HF, and composite events, defined from ICD-10 codes in hospital or death records.
  • Main analyses used multivariable-adjusted Cox proportional hazards regression, restricted cubic splines with 3 knots for dose-response, and isotemporal substitution models; sensitivity analyses included competing-risk regression, excluding missing covariate data, and excluding events within the first 2 years.

Limitations

  • Stated: the UK Biobank cohort consisted mainly of white participants, limiting generalizability; 7-day accelerometry may not capture long-term PA patterns and may overestimate PA due to monitoring awareness; wrist-worn accelerometers do not account for strength/type of exercise, have reduced accuracy for slow walking, and cannot record PA context.
  • Stated: most covariates were assessed at physical visits approximately 6 years before the accelerometer baseline, though the authors note prior evidence of stability over time; participants who agreed to wear accelerometers were generally healthier than average, so generalizability to people with worse health conditions should be cautious.
  • Evident from the text: the observational design limits causal inference, and despite extensive adjustment, residual confounding cannot be excluded.

    Study design and conductown data

    Sensitivity analyses showed all results remained largely robust using competing risk regression, excluding participants with missing data, and excluding events within first 2 years.

    “In the sensitivity analyses, all results remained largely robust by using competing risk regression (Supplementary Table 6), excluding participants with missing data on covariables (Supplementary Table 7), and excluding events occurring within the first 2 years (Supplementary Table 8).”

  • The paper relies on this without support.

    Missing covariate data are missing at random and can be validly imputed using multiple imputation.

    “To minimize the potential inferential, multiple imputations were performed to impute missing data using the “mice” R package.”
  • The paper relies on this without support.

    There is no unmeasured confounding of the observed associations between physical activity/sedentary behavior and vascular events.

    “Model 3 was additionally adjusted for cardiovascular risk factors (healthy diet score, sleep duration, smoking status, alcohol consumption, serum creatinine, family history of diabetes, history of cancers, history of depression, and use of blood glucose-lowering medications, blood pressure-lowering medications, and cholesterol-lowering medications).”
  • The paper relies on this without support.

    Individuals with type 2 diabetes mellitus and prediabetes are often older, relatively frail, or functionally compromised and may not tolerate long-lasting or more vigorous physical activity.

    “individuals with T2DM and prediabetes are often older, relatively frail, or functionally compromised and, therefore, may not tolerate long-lasting or more vigorous PA.”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Low-activity group size differs from Table 1

    Minor

    The results state that 3,822 participants had a low total volume of physical activity, but Table 1 assigns 3,828 to the low group. The table assigns 3,822 to the high group.

  • Ten-minute substitution uses conflicting time units

    Minor

    The results describe substituting 10 minutes per week of sedentary behavior with light activity, whereas Table 2 labels the corresponding substitution as 10 minutes per day.

  • Number of Cox models stated as three, but four are described

    Minor

    The statistical analysis says three multivariable-adjusted Cox models were used, then describes Models 1 through 4.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-09.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-09.

Cited sources are checked by gpt-6-sol.

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.
