Abstract

PURPOSE: While exercise has been shown to be beneficial in improving health-related quality of life (HRQOL) among cancer survivors, evidence is limited on the independent role of sedentary behavior. We examined how objectively measured sedentary time was associated with HRQOL among long-term cancer survivors. METHODS: This cross-sectional study included 54 cancer survivors, on average 3.4 years postdiagnosis, who were enrolled into an exercise trial designed to improve cognitive function. At baseline, we measured sedentary time and moderate-vigorous intensity physical activity with the ActivPal, cardiorespiratory fitness with treadmill testing, and self-reported HRQOL with an established scale (SF-36). In multivariate models, we regressed HRQOL on sedentary time (percent of waking time spent sitting and lying). RESULTS: Survivors with higher sedentary time had significantly poorer physical functioning (β = -0.50, p = 0.028), general health (β = -0.75, ptrend = 0.004), and physical summary scores (β = -0.34, p = 0.003). We did not observe associations between sedentary time and role-physical (p = 0.342), bodily-pain (p = 0.117), vitality (p = 0.095), social functioning (p = 0.407), role-emotional (p = 0.509), mental health (p = 0.494), or mental summary scores (p = 0.527). CONCLUSION: In this cross-sectional study of cancer survivors, we observed deleterious associations between sedentary time and aspects of physical HRQOL. Future prospective studies of sedentary time and HRQOL are needed to establish temporality and to facilitate the design of effective health promotion interventions for cancer survivors.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Survivors with high sedentary activity have significantly lower physical function, poor general health, and low physical score.

    “Survivors with a high sedentary activity pattern have a significantly lower physical function, poor general health and low physical score [19].”

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.
