Background: Regular exercise can mitigate side effects of cancer treatment. However, only a small proportion of adults with cancer meet exercise guidelines, and older adults (> 65 years) are underrepresented in cancer rehabilitation research. Peer support facilitates health-promoting behaviours in general populations, but interventions merging exercise and peer support for older adults with cancer are not examined. The purpose of this study was to determine the feasibility and preliminary effectiveness of a virtual partner-based peer support exercise intervention for older adult female cancer survivors., Methods: Older adult female cancer survivors with internet access and currently participating in < 150 min of moderate-vigorous physical activity per week were included in this study. Participants were matched with a partner and given a peer support guide, exercise guidelines, and a Fitbit Inspire©. In addition, intervention group dyads (AgeMatchPLUS) had weekly 1-h virtual sessions with a qualified exercise professional for 10 weeks. Dyads randomized to the control group (AgeMatch) independently supported their partner around exercise for 10 weeks. The primary outcome was feasibility, measured using retention and adherence rates. Secondary outcomes included exercise volume, social support, quality of life, physical function, and physical activity enjoyment. Descriptive statistics were used to report feasibility and an ANCOVA was used to explore between group differences on secondary outcomes at post-intervention (10 weeks post baseline) and post-tapering timepoints (14 weeks post baseline)., Results: Eighteen participants (9 dyads; mean age 72 years (SD: 5.7 years)) were included in the pilot trial. Retention and adherence rates to the AgeMatchPLUS intervention were 100% and 95% respectively. All but one participant was satisfied with the quality of their peer match. Preliminary effects were seen between group, favouring AgeMatchPLUS for exercise-related social support post-intervention (effect size (d) = 0.27, 95% CI = 0,0.54) and physical activity enjoyment at post-tapering (d = 0.25, 95% CI = 0,0.52) and favouring the AgeMatch group for 30 s sit-to-stand repetitions at post-tapering (d = 0.31, 95% CI = 0.004, 0.57). No other effects were found., Conclusions: A virtual partner-based exercise intervention for older adults with cancer is feasible and shows preliminary effect benefits. Findings inform future trials aimed at increasing exercise in older adults with cancer., Trial Registration: Clinicaltrials.gov (ID: NCT05549479, date: 22/09/22)., (© 2024. The Author(s).)

Background: Resistance training (RT) yields physical and psychological benefits for women living with and beyond breast cancer (WBC). This study examined the feasibility of a virtually delivered 8-week socially supportive RT intervention among WBC and assessed changes in physical activity and body image. Methods: A pilot single-arm 8-week pre-post intervention study design was implemented. Forty-one WBC were matched as exercise partners and asked to complete two RT sessions per week-one with a qualified exercise professional (QEP) and one with their peer. Data were collected at baseline (T1), post-intervention (T2), and 20 weeks post-baseline (T3). Results: The enrolment rate was 42%, the attendance rate for the QEP sessions was 63.8% and 40.0% for the peer sessions, and the retention rate was 87%. No adverse events were reported. Total weekly minutes of RT significantly ( p < 0.05) increased by 42 minutes/week during the intervention and significantly decreased by 25 min/week at follow-up. Upper and lower body muscle strength increased ( p < 0.01) during the intervention. Increased RT was associated with favorable activity self-perceptions. Conclusions: This pilot intervention study was feasible, safe, and demonstrated preliminary evidence for increasing RT time and strength among WBC. Virtually delivered socially supportive RT interventions can improve access for WBC.

Background: Initiating and maintaining exercise is challenging for women during and post-cancer treatment. Adopting a peer partner model to provide social support to be active may contribute to lasting behaviour change of both partners. Despite this, finding a "like peer" can be challenging., Purpose: To explore women's reasons for seeking an online exercise partner following a diagnosis with cancer (through  www.activematch.ca ). We also examined women's potential sociodemographic and cancer-related differences by reported reasons for wanting an exercise partner., Methods: Individuals creating an ActiveMatch profile completed demographic and physical activity questions (N = 199, M age (SD) = 51.9(10.8) years), including an open-ended question regarding their "reason for wanting an exercise partner". An inductive content analysis was completed focusing on the participants' peer exercise partner preferences. Additional chi-square tests were run to assess whether participants differed based on sociodemographic and cancer-related characteristics and their motivations to be active by category of "reason for wanting an exercise partner" endorsed in the open-ended question., Results: The participants' reasons for wanting an exercise partner were coded into seven categories, with most participants highlighting the reasons of motivation (52.3%), social support (48.7%), and accountability and adherence (26.6%). Women < 50 years of age were more likely to report accountability and adherence-related preferences for a partner. Those reporting endorsing weight loss as their primary reason for becoming active were more likely to be categorized as wanting a peer partner for motivation., Conclusions: While finding a peer partner can be challenging, matching women living with and beyond a cancer diagnosis based on their reason for wanting an exercise partner, as well as their reasons for wanting to be active, may be important to build successful peer exercise partnerships., (© 2024.

Objective: This systematic review aimed to summarize evidence for the feasibility and acceptability of psychosocial interventions for body image among women diagnosed with breast cancer and the study methods used to evaluate the interventions in question., Methods: Articles were identified via MEDLINE, CINAHL, CENTRAL, PsychINFO, and EMBASE. Inclusion criteria were: (1) peer-reviewed publication in English from 2000 onward with accessible full-text, (2) reported data on the feasibility and/or acceptability of psychosocial interventions and/or study methods, (3) included at least one measure of body image or reported a body-related theme, and (4) sample comprised women diagnosed with breast cancer. All study designs were eligible. Two reviewers independently performed study selection, data extraction, and quality assessment., Results: Sixty-two articles were included. Participants and comparator groups varied as did interventions. Feasibility and acceptability of the interventions and study methods were inconsistently operationalized and reported across studies. Evidence of feasibility and acceptability was heterogeneous within and across studies, though mostly positive., Conclusion: Published psychosocial interventions for body image and study methods are generally feasible and acceptable. Findings should be used to advance the development, implementation, and evaluation of interventions designed to improve outcomes (body image or otherwise) for women diagnosed with breast cancer., Systematic Review Registration: This review was registered with the International Prospective Register of Systematic Reviews (PROSPERO; ID: CRD42021269062, 11 September 2021)., (© 2024 The Authors.

Introduction: Body-related shame is a negative self-conscious emotion that is heightened during adolescence and is associated with several adverse outcomes. Of particular interest, and informed by Objectification Theory, body-related shame may impact attentional focus because the experience of this intense emotion may limit cognitive resources required to effectively engage in tasks. The purpose of the present study was to examine the association between body-related shame and attentional focus over time during adolescence., Methods: Adolescents (n = 160; M age  ± SD = 16.05 ± 0.98; 80% self-identifying girls) completed an online survey in 2022 at baseline (Time 1) and 3 months later (Time 2). Stepwise regression was used to test the association between body-related shame and attentional focus, with weight perception included as a covariate., Results: The regression model demonstrated that higher body-related shame predicted poorer attentional focus 3 months later (β = -0.44, p < .001), after controlling for weight perception (14% variance explained in attention)., Conclusions: Findings support and extend theoretical tenets by highlighting the potential importance of targeting body-related shame to reduce the negative impact on attentional focus among adolescents., (© 2023 The Authors.

Background: Physical activity (PA) can be a beneficial strategy to mitigate physical, emotional, and social-related challenges in women living beyond breast cancer treatment (WBC). However, PA levels among WBC remain low. Optimizing social support provided in a peer-matched setting may increase PA behavior. Unfortunately, factors that lead to an ideal peer-match among WBC are not well understood. The purpose of this study was to contextualize the natural social support environment and PA behavior in newly formed peer WBC dyads participating in an ecological momentary assessment study., Methods: WBC were matched with a partner and provided with a Fitbit activity tracker. Social support was measured using 21-daily surveys, and a 3-week follow-up survey. Descriptive statistics were calculated. Open-ended survey questions were analyzed using content analysis. Data were analyzed based on (i) social support types (informational, tangible, esteem, and emotional support); and (ii) WBC' reports of being in a good, neutral, or poor match at the end of the study., Results: Women (n = 46; Mage = 42.4 ± 7.6 years; 89.2% stage I-III breast cancer) connected with their partner (58.1%) and participated in moderate-vigorous PA (MVPA)(77.1%) on most days over the 21-day study period. Women were identified as being in good (63%), neutral (20%), or poor (17%) dyad matches. The most frequently documented social support received by WBC was esteem support. Participants in a good match were more likely to report receiving all types of social support compared to neutral or poor matches., Conclusion & Clinical Implications: Findings describe the social support characteristics important to WBC for facilitating their PA participation in a partner-based setting. This study provides valuable insight that can inform the development of partner-based PA interventions for WBC., (© 2023. The Author(s).)

Purpose: Exercise and social support are non-pharmacological strategies that improve health and wellbeing in women treated for breast cancer (WTBC). However, strategies to facilitate support and exercise in WTBC are typically resource intensive. The purpose of this study was to examine whether various forms of social support received from a matched peer were associated with increased exercise among WTBC., Methods: A daily diary study was conducted to examine naturally occurring social support as it relates to daily exercise behavior. Forty-six WTBC were matched (23 pairs) and completed pre-screening survey assessing eligibility and baseline levels of exercise. Participants were given Fitbit devices to track physical activity behavior and completed daily surveys across 3 weeks assessing perceptions of exercise-related social support at fixed times at the end of each day., Results: Mixed models accounting for day of study, baseline support, and baseline exercise levels revealed that higher levels of daily exercise-related tangible social support were associated with more daily steps (b = 506, SE = 143) and more light physical activity (LPA) minutes (b = 7.01, SE = 3.15). Informational social support was associated with higher moderate to vigorous physical activity (MVPA) minutes (b = 3.18, SE = 1.60)., Conclusions: Overall, peer matching programs aimed at increasing exercise-related social support among WTBC might encourage exercise behaviors, especially among women who share exercise-specific information (e.g., benefits, type, activities)., (© 2023.

Physical activity (PA) can help manage cancer treatment-related side effects and improve well-being following treatment; however, resuming PA after a period of inactivity due to cancer can be challenging. The purpose of this study was to explore adolescents and young adults (AYAs) experiences transitioning back into PA after a period of inactivity due to cancer treatment. Twelve previously active AYAs ( M age = 30 ± 5.8 years) were purposefully sampled and engaged in a semi-structured interview. The following four themes were generated through a reflexive thematic analysis: PA is described as important and valuable; navigating one's appearance and fitness changes after cancer treatment within the PA context; supportive care is essential to successful PA transitions; and juxtaposed environments: fitness facilities, cities, and green spaces. Developing strategies aimed at gradually transitioning into PA should be a priority to improve AYAs' well-being through survivorship.

Physical activity (PA) is important for managing the side effects and long-term outcomes of cancer treatment, yet many adolescents and young adults diagnosed with cancer (AYAs) are not meeting PA guidelines. Body image and social support are two factors that can influence PA behavior and require further attention in this population. The purpose of this study was to examine the associations between body image, social support, and PA among AYAs. An online cross-sectional survey administered through the Research Electronic Data Capture platform was used to assess self-reported body image (body-related self-conscious emotions of appearance and fitness shame, guilt, authentic pride, and hubristic pride), social support (general and cancer-specific), and PA (mild, moderate-to-vigorous, and resistance exercise) in AYAs ( N = 119; M age = 34.5 ± 5.5 years). Based on findings from path analyses, body image and social support were directly associated with PA ( R 2 = 0.09-0.33). Social support was also directly associated with body image. However, there were no indirect effects. These findings provide preliminary support for the influential role of appearance and fitness body-related emotions and cancer-specific social support on PA. The results have important implications for the development of targeted strategies aimed at improving body image (e.g., cognitive dissonance and compassion-focused interventions) and social support (e.g., facilitating the provision of cancer-specific support), with the overall goal of increasing AYAs' PA., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Vani, Sabiston, Trinh and Santa Mina.)

Background: Peer-based exercise interventions that cultivate new opportunities for support with a fellow cancer survivor may result in increased exercise volume. It is not clear whether adding qualified exercise professional (QEP) support to peer-based interventions improves health outcomes. Therefore, the purpose of this study is to determine whether breast cancer survivor (BCS) dyads who receive 10 weekly sessions of virtually delivered QEP support have improved outcomes compared to BCS dyads who do not receive QEP support., Methods: Participants Adult BCS with medical clearance for exercise, who have an internet-connected device, and currently engage in < 150 min of moderate-intensity exercise per week. Intervention BCS will be matched using evidence-based criteria. The intervention group will receive dyadic exercise information sessions and a program tailored by a QEP for 10 weeks (intervention period) and have access to the QEP for an additional 4 weeks (tapering period). The control will not receive any QEP support. Outcomes The primary outcome is post-intervention self-reported exercise volume. Secondary outcomes include device-assessed exercise volume (i.e., Fitbit), social support, and health-related quality of life. Randomization 108 participants, matched in dyads, will be randomized 1:1 to the MatchQEP or Match groups using a web-based scheme. Statistical analysis Outcomes will be measured at baseline, post-intervention, post-tapering, and at 12 weeks post-intervention follow-up., Discussion: The findings from this RCT will determine if matched BCS dyads who receive 10 weeks of virtually delivered QEP support have higher levels of self-report and device-measured exercise, social support, and health related quality of life compared to matched dyads without QEP-delivered exercise guidance. To our knowledge this will be the first study to assess the combined effect of peer- and QEP support on exercise volume. Project findings will inform and optimize intervention methods aimed to increase exercise among BCS through accessible exercise supports., Trial Registration: The study is registered on ClinicalTrials.gov (study identifier: NCT04771975, protocol Version Number: 2, date: July 22, 2021)., Competing Interests: Competing interestsThe authors declare that they have no competing interests., (© 2021.

There has been a surge in "quarantine15" social media posts during the self-isolation and lockdowns associated with the COVID-19 global pandemic. Given the influence of other body and weight-centered social media content (e.g., Fitspiration, Fatspiration) on body image and weight stigmatizing thoughts and attitudes, characterizing the features of quarantine15 content is an imperative first step towards understanding its impact on those who view it. Therefore, the present study is a content analysis of quarantine15 content on Instagram. A total of 668 posts were sampled using the hashtag quarantine15, and systematically analyzed for features related to positive and negative body image, as well as weight stigma. The results showed that the posts containing human figures (57.5 %) showcased individuals who were perceived as lower-weight (88.8 %), White (70.3 %), and women (87 %). Approximately one-third (34.4 %) of the images containing individuals were considered objectifying. Posts also perpetuated the controllability of weight through diet (51.5 %) and physical activity (27.5 %), while 46.9 % expressed dislike towards higher-weight bodies. Future experimental research in this area will be important for understanding both the acute and long-term effects of viewing quarantine15 content on body image, weight stigmatizing attitudes and thoughts, and internalized weight stigma., Competing Interests: Declaration of Competing Interest The authors report no declarations of interest., (Copyright © 2021 Elsevier Ltd.

Objective: Cancer and treatment can produce temporary or permanent body changes, which may affect the body image (BI) of adolescents and young adults diagnosed with cancer (AYAs). This evidence has not been comprehensively summarized. A scoping review was conducted to explore the available evidence on BI among AYAs and identify the definitions, theories, models, frameworks, measures, and methods used to assess BI., Methods: Databases MEDLINE, EMBASE, PsycINFO (via Ovid) and CINAHL and Gender Studies (via EBSCO) were searched to identify published studies from 1 January 2000 to 25 November 2019. Inclusion criteria were: qualitative, quantitative, or mixed methodology; at least one BI-related measure or theme; published in English; and majority of the sample between 13 and 39 years at diagnosis and a mean age at diagnosis between 13 and 39 years. Two authors screened the titles, abstracts, and full-text articles and data were extracted and summarized., Results: The search yielded 11,347 articles and 82 met inclusion criteria. Articles included 45 quantitative, 33 qualitative, and four mixed-methods studies. The majority of studies used cross-sectional designs, while BI definitions, theories, models, frameworks, and measures were varied. Studies explored descriptive, psychological, physical, coping, and social factors, with BI being described most often as an outcome rather than a predictor., Conclusions: Theory-based research that employs a holistic BI definition and uses longitudinal or intervention study designs or a qualitative methodology is needed to better understand the BI experience of AYAs and inform the development of strategies and programs to reduce BI concerns and increase positive body experiences., (© 2021 John Wiley & Sons Ltd.)

Purpose: Exercise and physical activity (hereafter, collectively referred to as PA) preferences and benefits are becoming increasingly well characterised in cancer survivors, yet evidence from adolescent and young adult cancer survivors (AYAs) is scant. We describe the overall PA behaviour and support preferences of AYAs and explore subgroup differences to inform AYA-specific research and support., Methods: AYAs diagnosed with cancer between the ages of 18-39 years, irrespective of current age, were approached in clinic at a large cancer centre for this cross-sectional survey that assessed self-reported demographics, medical history, PA behaviour and PA support preferences., Results: A total of 318 AYAs completed the survey. Approximately 40% of AYAs were not meeting PA guidelines, and only 5% reported engagement with cancer PA support services. Most AYAs wanted PA support (78%), to increase PA levels (70%), and were interested in engaging in PA interventions that were individually supervised (82%), home-based (79%), performed ≥ 3 days/week (75%) and for ≥ 30 minutes/session (78%), offered following treatment (63%), restricted by age (63%), and involved strength (83%), walking (78%), and flexibility (75%) exercise. PA preferences most often differed according to sex, treatment status, current PA behaviour and PA support setting., Conclusion: AYAs have a great capacity and interest in specific types of PA support. Poor engagement with existing PA support services highlights the need for further AYA-specific research. Better understanding of AYAs' unique PA behaviour and support preferences can inform the development of urgently needed research and support services for this understudied and rapidly growing population.

Exploring tenets of basic psychological needs theory, the objective of this study was to examine the association between psychological needs satisfaction, exercise behavior, and physical and mental health among testicular cancer survivors. The present study investigated whether psychological needs satisfaction was directly associated with increased self-rated health, and if this relationship was mediated by engagement in exercise. Testicular cancer survivors ( N = 135; M age = 32.45; SD = 7.63) self-reported current psychological needs satisfaction, exercise behavior, and perceived global physical and mental health during routine oncology visits. Associations were examined using path analysis. Psychological needs satisfaction was a positive correlate of both self-rated physical and mental health in this sample, and exercise mediated the association between needs satisfaction and self-rated physical health. This study supports the assumptions underpinning basic psychological needs theory in this unique clinical population. Based on the findings, exercise engagement represents one mechanism associated with perceived health after cancer. Supportive care interventions should aim to enhance satisfaction of psychological needs and investigate exercise as a mechanism underpinning the relationship between needs satisfaction and perceived health in testicular cancer survivors.

Background: The purpose of this study was to describe body image among young adult (YA) cancer survivors and examine relationships between body image and personal, medical, and psychosocial variables. Methods : YAs ( n = 522; M age = 34 ± 6 years) completed an online survey and data were analyzed using descriptive statistics, bivariate correlations, and appropriate tests of mean differences. Results : Higher body image concerns were related to less time since diagnosis, lower post-traumatic growth and social support, greater distress, and a higher number of treatments received ( rs = .09 to .42; ps < .05). Body image concerns were higher for those currently on treatment ( p < .05). Conclusions : Findings suggest greater attention to YAs' body image is necessary. Specifically, longitudinal research and the development of strategies dedicated to reducing body image concerns among YAs are needed.

Embarrassment is an understudied self-conscious emotion both experienced globally and in the context of the body. Drawing from affective body image tenets, this investigation aimed to better understand body-related embarrassment in a final sample of 187 adolescent and young adult males and females. A thematic content analysis was used to analyze self-report narratives from a relived emotion task and participants completed a self-report survey about the social environmental features of the emotional experience. Seven first-order themes and twenty-two second order themes were identified. Contexts for experiences of body-related embarrassment primarily included school, swimming pool/beach, sport and non-sport change rooms, and other sport or physical activity settings. Body-related embarrassment most often occurred when five or more individuals were present. Antecedents included fear of or actual negative evaluation, social comparisons, body exposure, and inadequacy compared to an internal standard. Outcomes included affective states and cognitive (e.g., avoidance) and behavioral (e.g., appearance management) outcomes. Compared to females, males reported less self-consciousness and were less likely to experience embarrassment around the other gender. Understanding the elicitation and experience of different emotions such as body-related embarrassment can guide theory and practice and may help to develop specific and unique interventions to address differing emotions., (Copyright © 2019 Elsevier Ltd.
