Abstract

Objectives: To prospectively examine associations between accelerometer‐measured physical activity ( PA ) and mortality in older women, with an emphasis on light‐intensity PA . Design: Prospective cohort study with baseline data collection between March 2012 and April 2014. Setting: Women's Health Initiative cohort in the United States. Participants: Community‐dwelling women aged 63 to 99 (N = 6,382). Measurements: Minutes per day of usual PA measured using hip‐worn triaxial accelerometers, physical functioning measured using the Short Physical Performance Battery, mortality follow‐up for a mean 3.1 years through September 2016 (450 deaths). Results: When adjusted for accelerometer wear time, age, race‐ethnicity, education, smoking, alcohol, self‐rated health, and comorbidities, relative risks (95% confidence intervals) for all‐cause mortality across PA tertiles were 1.00 (referent), 0.86 (0.69, 1.08), 0.80 (0.62, 1.03) trend P = .07, for low light; 1.00, 0.57 (0.45, 0.71), 0.47 (0.35, 0.61) trend P < .001, for high light; and, 1.00, 0.63 (0.50, 0.79), 0.42 (0.30, 0.57) trend P < .001, for moderate‐to‐vigorous PA (MVPA). Associations remained significant for high light‐intensity PA and MVPA ( P < .001) after further adjustment for physical function. Each 30‐min/d increment in light‐intensity (low and high combined) PA and MVPA was associated, on average, with multivariable relative risk reductions of 12% and 39%, respectively ( P < .01). After further simultaneous adjusting for light intensity and MVPA, the inverse associations remained significant (light‐intensity PA : RR = 0.93, 95% CI = 0.89–0.97; MVPA : RR = 0.67, 95% CI = 0.58–0.78). These relative risks did not differ between subgroups for age or race and ethnicity (interaction, P ≥ .14, all). Conclusion: When measured using accelerometers, light‐intensity and MVPA are associated with lower mortality in older women. These findings suggest that replacing sedentary time with light‐intensity PA is a public health strategy that could benefit an aging society and warrants further investigation.

  • Objectively measured physical activity levels, categorized into sedentary behaviour, light PA and MVPA, can be used to assess the risk of cardiovascular and all-cause death.

    “Objectively measured PA levels, categorized into sedentary behaviour, light PA and MVPA, can be used to assess the risk of cardiovascular and all-cause death”
  • Wearable-measured physical activity has an inverse dose-dependent relationship with all-cause mortality.

    “Several studies have shown wearable-measured physical activity to have an inverse dose-dependent relationship with all-cause mortality5,34–38.”
  • MVPA measured with triaxial accelerometers is associated with lower mortality than light physical activity or sedentary behaviour in several US cohorts and a Swedish population-based cohort.

    “Moderate-to-vigorous physical activity (MVPA), measured with the use of triaxial accelerometers, was associated with a lower mortality than light physical activity or sedentary behaviour in several US cohorts and in a Swedish population-based cohort34–38.”

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.
