Does a peer-led exercise intervention affect sedentary behavior among breast cancer survivors?

ABSTRACT: OBJECTIVE:Sedentary behavior is recognized as an independent risk factor for chronic diseases. Cancer survivors report high levels of sedentary behavior. In secondary analyses, we examined the effects of an exercise intervention on sedentary behavior (sitting time) among breast cancer survivors. METHODS:Seventy-six breast cancer survivors (mean age = 55.62 y, mean 1.1 y since diagnosis) were randomized to receive either a 12-week telephone-delivered exercise intervention from peer volunteers or a contact control condition. The intervention did not specifically address sitting time. Participants' sedentary behavior was assessed for 7 days at baseline, 12 weeks, and 24 weeks via self-report and objective measurement (accelerometer). RESULTS:At baseline, our sample reported sitting for 7.75 hours/day (10.98 h/d by accelerometer data). Spearman rank correlations showed significant positive correlations at baseline between sitting time measured by self-report and accelerometer (? = 0.37; P = .002) in the entire sample. There were no significant changes over time within group nor were there any significant intervention effects on sitting time (self-report and objective) at 12 and 24 weeks (all P's > .05). CONCLUSIONS:An exercise intervention that did not focus specifically on sitting time did not affect sedentary behavior among breast cancer survivors. Intervention components that specifically target sitting behavior are needed to reduce this risk behavior among survivors.

Project description:BackgroundYounger breast cancer survivors consistently report a greater impact of their cancer experience on quality of life compared with older survivors, including higher rates of body image disturbances, sexual dysfunction, and fatigue. One potential strategy to improve quality of life is through physical activity, but this has been understudied in younger breast cancer survivors, who often decrease their activity during and after cancer treatment.ObjectiveThe aim of this study is to explore the feasibility and acceptability of a technology-based, remotely delivered, peer-led physical activity intervention for younger breast cancer survivors. We will also assess the preliminary impact of the intervention on changes in physical activity and multiple aspects of quality of life.MethodsThis study is a community-academic partnership between University of California, San Diego and Haus of Volta, a nonprofit organization that promotes positive self-image in younger breast cancer survivors. This ongoing pilot study aims to recruit 30 younger breast cancer survivors across the United States (<55 years old, >6 months post primary cancer treatment, self-report <60 min of moderate-to-vigorous-intensity physical activity [MVPA]) into a 3-month peer-delivered, fully remote exercise program. Participants will complete 6 biweekly video chat sessions with a trained peer mentor, a fellow younger breast cancer survivor. Participants will receive a Fitbit Charge 3; weekly feedback on Fitbit data from their peer mentor; and access to a private, in-app Fitbit Community to provide and receive support from other participants and all peer mentors. At baseline, 3 months, and 6 months, participants will complete quality of life questionnaires, and MVPA will be measured using the ActiGraph accelerometer. Feasibility and acceptability will be explored through a mixed methods approach (ie, quantitative questionnaires and qualitative interviews). Intervention delivery and adaptations by peer mentors will be tracked through peer mentor self-evaluations and reflections, review of video-recorded mentoring sessions, and monthly templated reflections by the research team.ResultsRecruitment began in September 2019. As of February 2020, the physical activity intervention is ongoing. Final measures are expected to occur in summer 2020.ConclusionsThis study explores the potential for physical activity to improve sexual function, body image, and fatigue, key quality of life issues in younger breast cancer survivors. Using peer mentors extends our reach into the young survivor community. The detailed process evaluation of intervention delivery and adaptations by mentors could inform a future hybrid-effectiveness implementation trial. Finally, remote delivery with commercially available technology could promote broader dissemination.Trial registrationClinicalTrials.gov NCT04064892; https://clinicaltrials.gov/ct2/show/NCT04064892.International registered report identifier (irrid)DERR1-10.2196/18420.

Project description:IntroductionMany stroke survivors have unmet psychosocial needs during the recovery phase following a stroke. There is emerging evidence that peer support interventions may play a valuable role in managing stroke. However, evidence regarding the effectiveness of peer support interventions on the psychosocial outcomes of stroke survivors is uncertain. This study aims to develop a nurse-led peer support intervention for stroke survivors based on the Person-Environment-Occupation-Performance Model and evaluate its effects on the psychosocial outcomes of stroke survivors.Methods and analysisThis is an assessor-blinded two-arm randomised controlled trial. A convenience sample of 120 stroke survivors will be recruited from two community centres and one rehabilitation unit in Yangzhou, a medium-sized city in eastern China, with 60 participants each in the intervention and control groups. The participants allocated to the intervention group will receive the nurse-led peer support intervention, which includes 6 weekly peer support sessions facilitated by a nurse and at least one peer facilitator. Participants randomised to the control group will receive the same dose of interpersonal interaction as intervention participants, including weekly individual face-to-face session for 6 weeks. The primary outcomes are social participation and participation self-efficacy. The secondary outcomes are psychosocial distress, social support, stigma towards disease, self-efficacy in managing chronic conditions and quality of life. Data will be collected at baseline, immediately after the intervention and 3 months after the intervention. A process evaluation will be conducted qualitatively and quantitively to examine the mechanism by which the intervention impacts the psychosocial outcomes of stroke survivors. All outcomes will be analysed following the intention to treat principle. Generalised Estimation Equation models will be used to assess the intervention effect.Ethics and disseminationThis protocol was approved by the Joint Chinese University of Hong Kong-New Territories East Cluster Clinical Research Ethics Committee (CREC Ref. No.: 2021.196-T). All participants will be required to provide written informed consent. Results of the study will be disseminated through publication in peer-reviewed journals and presentation at local or international conferences.Trial registration numberChiCTR2100050853.
