Effects of a Clinic-Based Exercise Program on Sleep Disturbance Among Cancer Survivors.

ABSTRACT: Introduction: Sleep disturbance is the second leading negative side effect reported by cancer survivors, and evidence exists to suggest that exercise may improve sleep for cancer survivors. This study examined changes in sleep following a 3-month, clinic-based exercise program among a diverse group of cancer survivors.

Methods: Single group, pre-post study design. Participants were enrolled in a supervised exercise program which consisted of moderate intensity aerobic and resistance training, twice per week for 3-months. To be eligible, individuals had to be diagnosed with cancer, and undergoing, or within 6-months of completing chemo and/or radiation therapy. Sleep was assessed at pre-and post-program using 3 self-report questions as part of a standard wellness assessment conducted at the program's facility. Changes in categorical outcomes were evaluated using McNemar and Wilcoxon Signed-Rank Tests.

Results: Participants (N = 94) were mostly female (68.1%, N = 64), mean age = 54.26 ± 14.26 (20-78), and diagnosed with more than 8 different cancer types. Half (N = 48, 51.1%) of participants improved on 1 or more of the questions assessing sleep. At post-program, 39% of participants reported that they did not awaken feeling rested versus 48% at pre-program (P = .08). At post-program, 47% reported awakening ?1 time per night versus 46% at pre-program (P = .97), and 17% reported poor or very poor sleep quality at post-program versus 24% at pre-program (P = .16). There were no differences in demographic, cancer-related, psychosocial, and physical fitness variables between participants who improved on any of the questions assessing sleep versus those who did not.

Conclusions: A clinically implemented exercise program may help some cancer survivors improve sleep, however more studies utilizing validated, objective measures of sleep are needed to confirm effectiveness.

Project description:BackgroundThe purpose was to prospectively examine the effects of sedentary behaviors on subjective memory impairment in breast cancer survivors (BCS) and the extent to which sleep disturbances mediated this pathway.MethodsBCS (N = 380; Mage = 57.38 ± 9.25 years) completed questionnaires assessing demographics, health history, sitting behaviors, sleep disturbance, subjective memory impairment, and moderate-to-vigorous physical activity (MVPA) at baseline and 6-month follow-up. A subsample (N = 300) wore an accelerometer to objectively estimate sedentary time and MVPA. Structural equation modeling was used to test direct and indirect effects of self-reported and objectively estimated sedentary behaviors on memory impairment (through sleep disturbance) across time. Models were adjusted for demographic, clinical, and MVPA covariates.ResultsAt baseline, more total daily sitting (γ = 0.23), occupational sitting (γ = 0.11), television viewing (γ = 0.15), and computer use (γ = 0.22) were associated with greater sleep disturbance, which was associated with greater memory impairment (γ = -0.22). Indirect effects of self-reported sitting on memory were significant. At follow-up, increased total daily sitting (γ = 0.08) and computer use (γ = 0.14) predicted increased sleep disturbance, which predicted increased memory impairment (γ = -0.09). The indirect path from increased computer use to memory impairment was significant (β = -0.01). In the accelerometer subsample, greater daily sedentary time at baseline was associated with less sleep disturbance (γ = -0.14) and memory impairment (indirect effect: β = 0.03).ConclusionsFindings provide early evidence that sedentary contexts may differentially influence sleep disturbance and memory impairment in BCS. Computer use and television viewing may pose the strongest risks to cognitive health. Disparate findings between objective and subjective sedentary measures warrant further research.

Project description:BackgroundMusculoskeletal (MSK) pain is highly prevalent worldwide, resulting in significant disability, and comorbid sleep disturbances. Digital therapy for MSK pain can provide significant improvements in care access, alongside pain and disability reductions. However, studies on the effect of such programs on sleep are lacking.PurposeTo evaluate the impact on pain-related sleep impairment after a 12-week remote multimodal digital care program (DCP) for MSK conditions.Patients and methodsThis is an ad-hoc analysis of a decentralized single-arm study into engagement and clinical outcomes after a DCP for MSK rehabilitation. Patients were stratified by baseline sleep disturbance, based on sleep questions in the questionnaires: Oswestry Disability Index, Neck Disability Index, and the Quick Disabilities of the Arm, Shoulder and Hand questionnaire. Additional outcomes were pain, Generalized Anxiety Disorder 7-item scale, Patient Health 9-item questionnaire, Work Productivity, and Activity Impairment, and program engagement.ResultsAt baseline, 5749 patients reported sleep disturbance (78.0% of eligible patients). These reported significantly worse clinical outcomes at baseline than patients without sleep disturbance (all p<0.001). Patients with comorbid sleep disturbance showed improvements in sleep, with a significant proportion reporting full recovery at program completion: 56% of patients with upper limb conditions (including 10% of patients with severe sleep disturbance at baseline), and 24% with spine conditions. These patients also reported significant improvements in all clinical outcomes at program completion. Engagement and satisfaction were high, and also higher than in patients without sleep impairment.ConclusionThis is the first study of its kind investigating the effect of a completely remote DCP for MSK pain on sleep. Patients reporting comorbid sleep disturbance had significant improvement in sleep, alongside pain, mental health and work productivity at program completion. The results suggest that a DCP for MSK pain can improve sleep disturbances in patients with upper limb and spine conditions.
