Purpose: The potential health benefits of physical activity (PA) for women with breast cancer may be reduced by related symptoms of depression and anxiety. The purpose of this study was to examine the relationship between total Hospital Anxiety and Depression Scale (HADS) scores on depression and anxiety and PA measured ...
Background: Standard-of-care (SOC) cancer treatments are primarily aimed at reducing size and progression of a tumor. There is a need for successful supplemental anabolic therapies to combat cancer cachexia in addition to these SOC treatment modalities. Anabolic interventions, including testosterone and amino acid supplements, may be beneficial in reducing and/...
Background: This study prospectively examined patterns of objectively-assessed sedentary time and moderate-to-vigorous physical activity (MVPA) during a one-year period following completion of primary treatment among breast cancer survivors. The potential moderating effect of weight status on sedentary and MVPA time was also examined. Methods: Breast cancer survivors [N=177; M(SD)...
Background: Supportive care interventions are needed to reduce the chronic and late-appearing effects of breast cancer treatments. Reducing sedentary behaviour (SED) may be one promising strategy given the unique health benefits of low SED that are distinct from beneficial effects of moderate-to-vigorous intensity physical activity (MVPA). Objectives: To examine the ...
Aim: Research conducted on the general population indicates self-reported measures of physical activity and sedentary behaviour are inaccurate, however it is not clear if this also applies to cancer survivors. The aim of this study was to compare accelerometer-based and self-reported measures of moderate- to vigorous-intensity physical activity (MVPA) and ...
Purpose: The primary purpose of this study was to determine associations of accelerometer-assessed moderate- to vigorous-intensity physical activity (MVPA) and sedentary time with health-related quality of life (HRQoL) and physical function and well-being in colon cancer survivors. Methods: Colon cancer survivors (N=181) from Alberta, Canada (n=92) and Western Australia (n=89) ...
Abstract: Changes in DNA methylation may represent an intermediate step between the environment and human diseases. Little is known on whether behavioral risk factors may modify gene expression through DNA methylation. To assess whether DNA methylation is associated with different levels of physical activity, we measured global genomic DNA methylation ...
Background: Physical activity decreases risk of colon polyps and colon cancer and might reduce risk of colon cancer recurrence. Focusing on recent calls for translation of epidemiologic evidence into clinical care, our pilot study delivered an evidence-based physical activity intervention in adults with polyps, who are thus at elevated risk ...
Context Performance status (PS) is a predictor of response to chemotherapy but difficult to identify in patients with advanced lung cancer. It is measured using the ECOG scale, which relies on simple questions to assign a score. Accuracy in measurement is a concern. PS is closely related to physical activity, ...
Physical activity is becoming increasingly recognized as valuable to cancer patients during treatment and rehabilitation. Therefore strategies and measures to encourage patients to become more active and to achieve physical activity recommendations are of great importance. Purpose The study evaluated an accelerometer based biofeedback device by measuring the change of ...
