Abstract

Background: Sedentary behavior is prevalent among people with diabetes and is associated with unfavorable cardiometabolic health. However, there is limited evidence regarding the impact of replacing sedentary time (ST) with physical activity on mortality in people with prediabetes and diabetes. We prospectively examined the association between accelerometer-measured ST and mortality among people with prediabetes and diabetes after adjusting for demographic characteristics, lifestyle factors, and moderate- to vigorous-intensity PA (MVPA). We further determined the effect of replacing ST with equal time of different types of physical activities on all-cause mortality. Methods: We included 1242 adults with prediabetes and 1037 with diabetes from the National Health and Nutrition Examination Survey. Restricted cubic splines were fitted to determine the dose–response association between ST and overall mortality. Isotemporal substitution modeling was used to explore the hazard ratio (HR) effects of ST replacement. Results: During a median follow-up of 14.1 years, 424 adults with prediabetes and 493 with diabetes died. Compared with the lowest tertile of ST, the multivariable-adjusted HRs for all-cause mortality in the highest tertile were 1.76 (95% confidence interval [CI] 1.19, 2.60) for participants with prediabetes and 1.76 (1.17, 2.65) for those with diabetes. Additionally, a linear association between ST and all-cause mortality was observed in adults with prediabetes and diabetes, with HRs for each 60 min/day increment in ST of 1.19 (1.10, 1.30) and 1.25 (1.12, 1.40), respectively. Isotemporal substitution results indicated that individuals with prediabetes whose ST was replaced by 30 min of light-intensity physical activity (LPA) and MVPA had 9% and 40% lower all-cause mortality, respectively. In people with diabetes, replacing sedentary behavior with an equivalent time of LPA and MVPA was also associated with mortality risk reduction (HR 0.89; 95% CI 0.84, 0.95 for LPA; HR 0.73; 95% CI 0.49, 1.11 for MVPA). Conclusions: Higher ST was associated in a dose–response manner with an increased risk of premature mortality among adults with prediabetes and diabetes. Statistically replacing ST with LPA was potentially beneficial for health in this high-risk population.

  • Prior accelerometry-based studies specific to patients with type 2 diabetes were scant but all demonstrated significant risk reductions in mortality-related outcomes with higher volumes of physical activity.

    “Prior accelerometry-based studies specific to T2D patients were scant but all demonstrated significant risk reductions in mortality-related outcomes with higher volumes of PA, such as a 29% lower risk of premature all-cause mortality for every 60-min increase in daily ambulatory movement in the NHANES and a 2.6% lower risk of a composite CVD outcome including all-cause mortality for every 100 MET-”

    From Accelerometer-derived physical activity and mortality in individuals with type 2 diabetes (2024) · cites this paper as [18]

    The Results (Isotemporal substitution analyses; page unavailable) report that replacing 30 minutes of sedentary time with light physical activity was associated with lower all-cause mortality among participants with diabetes. The same analysis did not show a statistically significant reduction for moderate-to-vigorous activity in that group. The paper does not establish that all prior accelerometry-based studies in type 2 diabetes found significant reductions, or report the cited 29% and 2.6% estimates. (LLM, conf=0.87)

  • Two studies from NHANES, a study from the Look AHEAD Trial, and a study from the Walking Away from Type 2 Diabetes trial all demonstrated significant risk reductions related to all-cause mortality with higher volumes of physical activity.

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.
