“…Of those 340 participants, 274 (50% of the 552 eligible breast cancer survivors invited) completed the study. The participants and non-participants did not differ in terms of age, socioeconomic status, breast cancer grade or time since diagnosis (6). Eighteen participants were missing data on one or more of the variables used in this analysis, leaving 256 participants in the current study.…”

Background Moderate-to-vigorous intensity physical activity (MVPA) has been inversely associated with waist circumference and body mass index among breast cancer survivors. Limited research has focused on behaviours that account for larger portions of the day [sleep, sedentary time, and light-intensity physical activity (LPA)]. In this study we investigated the interdependent associations of self-reported sleep, objectively-assessed prolonged and short bouts of sedentary time, total LPA and total MVPA with waist circumference and BMI in breast cancer survivors. Methods A cross-sectional sample of breast cancer survivors (N=256, mean age=60 years; mean time since diagnosis=3 years) wore an Actigraph® GT3X+ accelerometer during waking hours for seven days. Participants also completed the Pittsburgh Sleep Quality Index, and self-reported their waist circumference, height and weight. An isotemporal substitution approach was used in linear regression models to explore the associations of reallocating time to sleep, sedentary and active behaviours on waist circumference and BMI, after adjusting for potential confounders. Results Reallocating 30 minutes to total MVPA was associated with lower waist circumference when allocated from sleep (−2.50cm, 95% CI = −4.45cm, −0.56cm), prolonged sedentary time (−2.51cm, 95% CI = −4.38cm, −0.64cm) or LPA (−2.71cm, 95% CI = −4.72cm, −0.69cm). Reallocating 30 minutes of prolonged sedentary time to non-prolonged sedentary time was associated with lower waist circumference (−0.94cm, 95% CI = −1.79cm, −0.10cm). Similar results were observed for BMI. Conclusion/Impact Increasing MVPA levels and decreasing time spent in prolonged, unbroken sedentary bouts may be avenues for improving body composition in this population.

“…4 The continuum of evidence, from experiments in animals to large population studies, has demonstrated that higher volumes of sedentary behavior are associated with a range of negative physiologic effects, and some effects are thought to be distinct from not performing sufficient moderate-intensity to vigorous-intensity physical activity (MVPA). 11 Sedentary behavior in cancer survivors appears to be high, with accelerometer-based assessment indicating that, on average, cancer survivors spend between 8.2 and 10.8 hours per day sedentary, 12,13 which is higher than the general US National Health and Nutrition Examination Survey population aged ≥60 years. 11 Sedentary behavior in cancer survivors appears to be high, with accelerometer-based assessment indicating that, on average, cancer survivors spend between 8.2 and 10.8 hours per day sedentary, 12,13 which is higher than the general US National Health and Nutrition Examination Survey population aged ≥60 years.…”

BACKGROUND: High levels of sedentary behavior may negatively affect health outcomes in cancer survivors. A systematic review and meta-analysis was performed to clarify whether postdiagnosis sedentary behavior is related to survival, patient-reported outcomes, and anthropometric outcomes in cancer survivors. METHODS: The Ovid MEDLINE, EMBASE, CINAHL (The Cumulative Index to Nursing and Allied Health Literature), and SPORTDiscus databases were searched from study inception to June 2019. Studies of adults who had been diagnosed with cancer that examined the association between sedentary behavior and mortality, patient-reported outcomes (eg, fatigue, depression), or anthropometric outcomes (eg, body mass index, waist circumference) were eligible for inclusion. Meta-analyses were performed to estimate hazard ratios for the highest compared with the lowest levels of sedentary behavior for all-cause and colorectal cancer-specific mortality outcomes. The ROBINS-E (Risk of Bias in Nonrandomized Studies-of Exposures tool) and the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) system were used to assess the risk of bias and the strength of evidence, respectively. RESULTS: Thirty-three eligible publications from a total of 3569 identified articles were included in the review. A higher level of postdiagnosis sedentary behavior was associated with an increased risk of all-cause mortality (hazard ratio, 1.22; 95% CI, 1.06-1.41; heterogeneity [I 2 statistic], 33.8%) as well as colorectal cancer-specific mortality (hazard ratio, 1.53; 95% CI, 1.14-2.06; I 2 , 0%). No clear or consistent associations between sedentary behavior and patient-reported or anthropometric outcomes were identified. The risk of bias in individual studies ranged from moderate to serious, and the strength of evidence ranged from very low to low. CONCLUSIONS: Although avoiding high levels of sedentary behavior after a cancer diagnosis may improve survival, further research is required to help clarify whether the association is causal.

Background: There is limited research in advanced cancer patients (ACP) regarding association between objectively measured daytime activity and sleep (as measured by actigraphy), patient characteristics, and cancer symptoms (fatigue, sleep, anxiety, depression, cachexia, and symptom distress scores [SDSs]). Objectives: Our aim of the study was to determine the association between mean daytime activity (MDTA) and the following items: fatigue (FACIT-F), SDSs (Edmonton Symptom Assessment Scale [ESAS]), sleep quality (Pittsburg Sleep Quality Index [PSQI]), objective sleep variables (OSV) (sleep onset, sleep efficacy, wake after sleep onset, total sleep time), anxiety and depression (Hospital Anxiety and Depression Scale [HADS]), body composition scores, and overall survival (OS). We also examined the association between sleep [PSQI and OSV scores] and FACIT-F, HADS, and ESAS. Methods: Secondary analysis of a recent clinical trial of cancer-related fatigue in advanced cancer (NCT00424099). Association between MDTA and OSV (measured by actigraphy) during the first week of the study and patient characteristics, symptoms (FACIT-F, ESAS, HADS, and PSQI), and OS were analyzed. Results: Seventy-nine eligible patients were evaluable. The median age was 57 years. Median MDTA was 248.43 counts/minute. Multivariate analysis shows that low MDTA was significantly associated with age, gender, Functional Assessment of Cancer Therapy (FACT)-Functional Well-Being (FWB), ESAS dyspnea, HADS-anxiety, and total sleep time. MDTA was not associated with FACIT-F ( p = 0.997) and OS ( p = 0.18). Sleep quality (PSQI) was significantly associated with FACIT-F, HADS, ESAS anxiety, and depression, but none of these variables was associated with OSV. Conclusion: In ACP, lower MDTA was significantly associated with age, gender, FACT-FWB, ESAS dyspnea, HADS-anxiety, and total sleep time. Both sleep quality and cancer-related fatigue scores were strongly associated with depression and anxiety. More research is needed.

How sedentary and physically active are breast cancer survivors, and which population subgroups have higher or lower levels of these behaviors?

Abstract: Interventions to facilitate physical activity and reduce sedentary time among breast cancer survivors should consider comorbidity status and previous PA experience.
