Connectedness to the young adult cancer community and post-traumatic growth: A young adults with cancer in their prime study.

OBJECTIVE: For young adults (YAs) with cancer, connecting with peer cancer survivors can provide a unique sense of community and may enhance post-traumatic growth (PTG). This study examined the relationship between connectedness to the YA cancer community and PTG among YAs, independent of overall social support. METHODS: Data were obtained from the young adults with cancer in their prime study, a cross-Canada survey of YA cancer survivors. Participants were stratified by level of social support into two groups (low/high). Multivariable logistic regression was used to examine the association between PTG and connectedness to the YA community adjusting for respondent characteristics, and the interaction between support and connectedness. RESULTS: Of 444 respondents, mean age was 34.2 (SD = 6.0), time-since-diagnosis was 4.8 years (SD = 5.4), and 87% were female. Over two-thirds of respondents (71%) reported feeling connected to the YA community. Level of connectedness to the YA community did not differ by social support group, and interaction between social support and connectedness to the YA community was not significant. In the adjusted regression, connectedness to the YA community (aOR = 2.29, 95% CI: 1.10-4.91), high social support (aOR = 2.98, 95% CI: 1.36-6.74), greater time-since-diagnosis (aOR = 1.09, 95% CI: 1.04-1.15) and female sex (aOR = 2.21, 95% CI: 1.23-4.04) were associated with greater odds of moderate-to-high PTG. CONCLUSIONS: Feeling connected to a community of YA cancer peers was associated with moderate-to-high PTG among YAs, independent of overall perceived social support. Future efforts should increase access to YA cancer communities and foster a sense of connectedness among YAs with cancer.

Parent Support for Physical Activity and Motor Skills During Early Childhood: A Mixed-Methods Application of the Multi-process Action Control Framework.

BACKGROUND: Promoting physical activity (PA) and fundamental movement skills (FMS) in early childhood is necessary to address the high rates of inactivity in children. Parent support is a determinant of PA in children, however, parental intentions to support are not always translated into behavior resulting in an intention-behavior gap. PURPOSE: Positioned within the multi-process action control (M-PAC) framework, this study used an explanatory concurrent mixed-methods design to explore parents' intentions and support of PA and FMS during early childhood. METHODS: Parents (N=124) of children aged 3-4 years completed an online survey consisting of items assessing reflective (e.g., attitudes), regulatory (e.g., planning), and reflexive (e.g., habit) processes of M-PAC and intentions and support for child PA and FMS. A subset of parents (n=20) completed a semi-structured online interview guided by the M-PAC framework. RESULTS: Significantly more parents intended to support PA (71%) compared with FMS (44%; p<0.001) and successfully translated intentions into action for PA (57%) compared with FMS (27%; p<0.001). Discriminant function analysis showed parent behavior profiles for PA and FMS support were associated with a combination of reflective, regulatory, and reflexive processes, however, these differed based on support behavior. Qualitative findings highlighted parents' differential views on PA and FMS support and contextualized the psychological processes associated with each. CONCLUSIONS: Parent PA support interventions during early childhood should include strategies for supporting FMS. Interventions should prioritize fostering a combination of reflective, regulatory, and reflexive behaviors to translate intentions to support PA and FMS into behavior among parents of young children.

Promoting physical activity (PA) and fundamental movement skills (FMS) in early childhood is necessary to address physical inactivity in young children. Parent support is a known predictor of PA in children, however, parents who intend to support PA do not always follow through with these intentions. This is referred to as the intention­behavior gap. Applying the theoretical tenets of the multi-process action control framework, this study surveyed 124 parents of children aged 3­4 years on reflective (e.g., attitudes), regulatory (e.g., planning), and reflexive (e.g., habit) processes, intentions, and behaviors related to parent PA and FMS support. Follow-up interviews were completed with 20 parents to gain a deeper understanding of parent PA and FMS support behaviors. Survey findings showed that parents' intentions and support behaviors for their child's PA and FMS were associated with a combination of reflective, regulatory, and reflexive processes. Interview findings highlighted more favorable parent perspectives toward PA support compared with FMS and further explained the psychological processes associated with each. Future parent PA support interventions during early childhood should include FMS support strategies and foster a combination of reflective, regulatory, and reflexive behaviors to bridge the gap between intentions and support behaviors among parents of young children.

Exploring the reasons for wanting a peer partner to be physically active among women living with and beyond a cancer diagnosis: a content analysis.

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, Mage(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.

Does Participating in a Variety of Activities at a Variety of Locations or With Different People Predict Physical Activity Behavior Among Adolescents? The Mediating Role of Perceived Variety.

We examine whether adolescents' participating in a variety of physical activities, locations, and/or with a variety of people relates to physical activity 16 months later and whether perceptions of variety mediate these relationships. Adolescents (N = 369) completed measures indicating various physical activities they participated in, where they primarily participated, and with whom they primarily participated, at three time points over a year (averaged for baseline measures). Perceptions of variety was measured 8 months later. Physical activity was measured 16 months after baseline. Mediation analyses tested perceptions of variety as a mediator of variety support and physical activity. Results indicated that variety of activities and variety of locations were indirectly associated with physical activity through perceptions of variety. Participating in a breadth of physical activities in a variety of locations during adolescence is positively associated with perceptions of variety, which relates to physical activity 16 months later.

"It has to be more than exercise": exploring multiple perspectives to community-based exercise program design for persons with breast cancer.

PURPOSE: Connecting persons with cancer to exercise resources and/or supports requires a diverse team of professionals. As such, there is merit to engaging multiple individuals or "partners" along the cancer pathway to explore the relevant features of community-based exercise program (CBEP) design. The purpose of this study was to explore multi-partner perspectives to CBEP design for persons diagnosed with breast cancer (PWBC) to inform the implementation of a CBEP in a local setting. METHODS: PWBC, health care professionals and qualified exercise professionals participated in one of four 60-min focus group discussions. Rich dialogue about preferred program environments, program delivery teams, and core program practices was encouraged using a semi-structured discussion guide. Focus groups were audio recorded, transcribed verbatim, and analyzed using inductive thematic analysis. RESULTS: Five main themes were identified based on focus group discussions, each pointing to an important feature of CBEP design for PWBC. Themes included the desire for CBEPs to incorporate elements designed to improve cancer literacy, provide opportunities to participate with peers, foster self-efficacy, prioritize program accessibility, and meaningfully integrate CBEPs within a network of supportive cancer care. CONCLUSION: The collective effect of fostering such elements in CBEPs may serve to increase the uptake and maintenance of exercise among PWBC; ultimately enhancing their overall well-being and quality of life.

Matched and moving: exploring daily social support among women partnered for exercise after a breast cancer diagnosis.

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).

A scoping review of resilience among transition-age youth with serious mental illness: tensions, knowledge gaps, and future directions.

INTRODUCTION: The study of resilience among transition-age youth (aged 16-29 years) living with serious mental illness (SMI) has provided a promising new direction for research with the capacity to explore individuals' strengths and resources. However, variability in how resilience is defined and measured has led to a lack of conceptual clarity. A comprehensive synthesis is needed to understand current trends and gaps in resilience research among this population. The purpose of the current study was to map how resilience has been conceptualized and operationalized among transition-age youth with SMI, explore resilience factors and outcomes that have been studied, and recommend areas for future research. METHODS: A six-stage scoping review methodology was used to systematically identify relevant empirical literature across multiple databases (MEDLINE, EMBASE, PsycINFO, AMED, CINAHL, Scopus), addressing transition-age youth diagnosed with SMI and resilience. Topic consultation and reaction meetings were conducted to gather feedback from transition-age youth with SMI, researchers, and clinicians during the review process to enhance the applicability of the review findings. A meta-narrative approach was used to organize included studies into research traditions (i.e., paradigms of inquiry with similar storylines, theoretical and methodological orientations). Resilience factors and outcomes, and the consultative meetings, were analyzed using content analysis. RESULTS: Twenty-four studies met inclusion criteria (14 quantitative, 9 qualitative, 1 mixed-method). Four research traditions were identified, each contributing a unique storyline which conceptualized and operationalized resilience in slightly different ways: Stress Adaptation, Person-Environment Interactions, Recovery-Focused, and Critical and Cultural Perspectives. Resilience factors and outcomes were most commonly evaluated at the individual-level or within the immediate environment (e.g., personal characteristics, social support networks). Limited research has explored the influence of macro-level systems and health inequalities on resilience processes. Results from the consultative meetings further demonstrated the importance of health services and sociocultural factors in shaping processes of resilience among youth. CONCLUSION: The present results may be used to inform future work, as well as the development of age-appropriate, strengths-based, and resilience-oriented approaches to service delivery. Interdisciplinary and intersectional research that prioritizes community and youth engagement is needed to advance current understandings of resilience among transition-age youth with SMI.

Natural patterns of social support for physical activity participation in newly matched breast cancer survivor dyads.

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.

A time compositional analysis of the association between movement behaviors and indicators of mental health in young adults.

BACKGROUND: Movement behaviors (i.e., physical activity [PA], sedentary behaviors [SB], sleep) relate to mental health. Although movement behaviors are often analyzed as distinct entities, they are in fact highly inter-dependent (e.g., if an individual increases sleep, then PA and/or SB must be reduced) and these dependencies should be accounted for in the analysis. We tested whether perceptions of time spent in movement behaviors (i.e., moderate-to-vigorous intensity PA [MVPA], light physical activity [LPA], SB, and sleep) related to depressive symptoms and self-report mental health in young adults using a compositional analysis. We then estimated change in depressive symptoms with reallocation of time across movement behaviors using compositional time-reallocation models. METHODS: Data were drawn from the longitudinal NDIT dataset. Complete data were available for 770 young adults (Mage = 20.3, 55% females). RESULTS: The proportion of time spent in MVPA relative to other movement behaviors related to depressive symptoms non-significantly and to mental health significantly. Reallocating 15 min from MVPA to SB resulted in a significant (0.46 unit) increase in depressive symptoms, and reallocating 15 min of MVPA to LPA was associated with a (0.57) increase in depressive symptoms. CONCLUSION: These results indicate the importance of relative time spent in each movement behavior to mental health. Further research should examine these associations over time.

Body-related shame disrupts attentional focus over time in adolescence.

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; Mage ± 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 (ß = -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.

parkrun participation, impact and perceived social inclusion among runners/walkers and volunteers with mental health conditions.

Engagement in recreation can positively impact the physical and mental health of those experiencing mental health challenges; however, the impact of engaging in other aspects of such recreation, such as volunteering, remain largely unexplored in this population. Volunteering is known to have a wealth of health and wellbeing benefits among the general population; therefore, the impact of recreational-based volunteering for those with mental health conditions deserves to be explored. The current study sought to examine the health, social and wellbeing impacts of parkrun engagement among runners and volunteers living with a mental health condition. Participants with a mental health condition (N = 1661, M(SD)age = 43.4 (12.8) years, 66% female) completed self-reported questionnaires. A MANOVA was conducted to examine the differences in health and wellbeing impacts between those who run/walk vs. those who run/walk and volunteer, while chi-square analyses examined variables of perceived social inclusion. Findings suggest that there was a statistically significant multivariate effect of participation type on perceived parkrun impact (F (10, 1470) = 7.13; p < 0.001; Wilk's Λ = 0.954, partial η2 = 0.046). It was also found that for those who run/walk and volunteer, compared to those who only run/walk, parkrun made them more feel part of a community (56% v 29% respectively, X2(1) = 116.70, p < 0.001) and facilitated them meeting new people (60% v 24% respectively, X2 (1) = 206.67, p < 0.001). These results suggest that the health, wellbeing, and social inclusion benefits of parkrun participation are different for those who run and volunteer, compared to those who only run. These findings may have public health implications and clinical implications for mental health treatment, as they convey that it is not simply the physical engagement in recreation that may play a role in one's recovery, but also the volunteer aspect.

An organizational approach to exploring the determinants of community-based exercise program implementation for breast cancer survivors.

BACKGROUND: The majority of breast cancer survivors do not engage in sufficient levels of exercise. Community-based exercise programs (CBEP) may mitigate low rates of exercise participation; however, few programs exist. Previous research exploring the determinants of CBEP implementation for cancer survivors is limited in that it has predominantly focused on cancer survivor perspectives or it has failed to rely on a theoretical framework to explore determinants to implementation across various implementation domains. An organizational exploration of the determinants of CBEP implementation for breast cancer survivors is warranted to guide future program implementation. PURPOSE: The purpose of this study was to apply the Consolidated Framework for Implementation Research (CFIR) to explore the determinants of CBEP implementation for breast cancer survivors from a program provider perspective. METHODS: Data collection and analysis were guided by the CFIR. Program providers completed an online questionnaire and an interview. Transcripts were analyzed using inductive content analysis. Resulting codes were deductively mapped onto the CFIR. RESULTS: Seven barriers and seven facilitators were identified, with three key influencers (e.g., program awareness, financial support, and knowledge regarding the benefits of exercise for breast cancer survivors) cited as both barriers and facilitators to program implementation. Barriers primarily operated within the outer setting (e.g., needs and resources) domain of the CFIR, whereas facilitators and key influencers operated across multiple CFIR domains (e.g., culture and planning). CONCLUSIONS: Study findings provide insight into the current challenges to CBEP implementation experienced by program providers and highlight potential avenues for future exercise program development and implementation.

Physical activity and sedentary time: associations with fatigue, pain, and depressive symptoms over 4 years post-treatment among breast cancer survivors.

INTRODUCTION: Despite the recommendations for cancer survivors to engage in physical activity (PA), little is known about the effects of both PA and sedentary time (ST) on key health symptoms. This study prospectively examined the lifestyle behaviors of moderate-to-vigorous PA (MVPA) and ST as predictors of depressive symptoms, pain, and fatigue in breast cancer survivors using longitudinal data from early post-treatment to 4-year survivorship. METHODS: Breast cancer survivors (n = 199, mean(SD) age = 55.0(11.0) years) self-reported depressive symptoms, pain, and fatigue, and wore an accelerometer to measure MVPA and ST every 3 months during the first year (times 1 to 5) and 2 and 4 years (times 6 and 8) post-cancer treatment. Linear mixed models were adjusted for personal (e.g., age, BMI, education) and cancer (e.g., stage, time since treatment) variables. RESULTS: MVPA and ST were independent predictors of depressive symptoms, but not fatigue, and only ST was associated with pain over 4 years post-treatment. Higher levels of MVPA were associated with lower scores of depressive symptoms ([Formula: see text] (95%CI): - 0.062 (- 0.092, - 0.031) p < .001), whereas higher levels of ST were associated with higher scores of depressive symptoms ([Formula: see text] (95%CI): 0.023 (0.017, 0.028) p < .001). Higher levels of ST were associated with increased pain level over time ([Formula: see text] (95%CI): 0.017 (0.007, 0.027) p = .001). CONCLUSIONS: Rehabilitation interventions should aim to both increase MVPA and reduce ST to promote health and well-being among breast cancer survivors, in particular during the early post-treatment period.

Factors predicting gains in moderate-to-vigorous physical activity in prostate cancer survivors on androgen deprivation therapy.

BACKGROUND: Whether individual, environmental, and psychosocial factors predict changes in moderate-to-vigorous physical activity (MVPA) is poorly addressed in prostate cancer (PC) survivors undergoing androgen deprivation therapy (ADT). PURPOSE: This secondary analysis of a randomized controlled trial examined changes in MVPA following a supervised personal training (PT), supervised group-based (GROUP) program, or a home-based, smartphone-assisted exercise (HOME) intervention in PC survivors on ADT and explored individual, environmental, and psychosocial predictors of MVPA. METHODS: PC survivors on ADT underwent aerobic and resistance training for 6 months via PT, GROUP, or HOME. MVPA was captured via accelerometers and the Godin Leisure-Time Exercise Questionnaire. Changes in MVPA between groups were assessed using linear regression. The following predictors of MVPA were examined using Spearman correlations: the Neighborhood Environment Walkability Scale (NEWS); the Planning, Attitudes, and Behaviours (PAB) scale; the Relatedness to Others in Physical Activity Scale (ROPAS); and individual factors at baseline. RESULTS: Participants (n = 37) were 69.4 ± 6.5 years old and 78.4% were on ADT for ≥ 3 months. Changes in accelerometry-based bouts and MVPA as well as self-reported MVPA did not differ between groups at 6 months. The Aesthetics domain of the NEWS questionnaire at baseline was the strongest predictor of positive MVPA changes (r = .66). Attitude (r = .64), planning (r = .57), and motivation (r = .50) at baseline were also predictive of engaging in higher MVPA throughout the intervention. CONCLUSION: Changes in objective MVPA were modest. Additional emphasis on specific psychosocial and individual factors is important to inform theory-based interventions that can foster PA behavior change in PC survivors on ADT.

Physical activity motives have a direct effect on mental health.

Physical activity (PA) motives are associated with both moderate-to-vigorous intensity PA (MVPA) and mental health. Studies examining whether PA motives relate directly to mental health or indirectly through MVPA are lacking. This study examined the direct effect of five PA motives (i.e., enjoyment, competence, fitness, social, appearance) on mental health and their indirect effects through MVPA in adolescents. A total of 424 participants (57.1% females) ages 14-15 years from the longitudinal MATCH study were included. Mediation analyses, based on the counterfactual framework, assessed the natural direct effect of PA motives on mental health, and the natural indirect effects through MVPA. Separate models were conducted for each PA motive. Natural direct effects were observed for enjoyment ( ß Ì‚ [95%CI] = 2.12 [0.34, 3.90]), competence ( ß Ì‚ [95%CI] = 1.58[0.28, 2.88]), fitness ( ß Ì‚ [95%CI] = 1.42[0.04, 2.80]), and social ( ß Ì‚ [95%CI] = 2.32[1.03, 3.60]) motives. No natural direct effects were observed for appearance motives. A natural indirect effect through MVPA was observed for fitness motives, and no other natural indirect effects were found. Interventions and public health strategies in adolescents need to acknowledge the importance of enjoyment, competence social and fitness motives in PA to promote mental health, and integrate specific recommendations on the importance of the reasons why adolescents participate in PA.

A distance-based, randomized controlled trial for reducing sedentary behavior among prostate cancer survivors: a study protocol.

BACKGROUND: Prostate cancer survivors (PCS) experience long-term side effects beyond treatment such as fatigue, depression and anxiety. Quality and engaging supportive care programs are needed to reduce these chronic and debilitating effects. Independent of physical activity (PA), high volumes of sedentary behavior (SB) are associated with chronic disease-related risk factors and poorer cancer-specific quality of life (QoL). Simultaneously increasing PA and decreasing SB may be an effective health promotion strategy. Given that PCS may face several barriers to engaging in supervised programs, there is a need to develop and assess the efficacy of interventions that employ distance-based approaches for behavior change. The primary aim of this study is to determine the effects of a 12-week intervention (Fitbit + behavioral counselling) vs. Fitbit-only control group in reducing SB among PCS. Secondary outcomes include light-intensity PA, QoL, motivational outcomes, and patient satisfaction. METHODS: This two-armed, randomized controlled trial will recruit inactive PCS (stage I-IV) across Canada who self-report engaging in >8 hours/day of SB. Participants will be randomized to the intervention (n=60; Fitbit and behavioral support) or active control group (n=60; Fitbit-only). The intervention consists of the use of a Fitbit and a series of six behavioral support sessions (two group, four individual) to aid PCS in gradually replacing SB with light-intensity PA by increasing their daily step counts to 3,000 steps above their baseline values. The Fitbit-only control condition will receive a Fitbit and public health PA resources. The primary outcome is change in SB measured objectively using activPAL inclinometers. All secondary outcomes will be measured via self-report, except for PA which will be measuring using Fitbits. Data will be collected at baseline, post-intervention, and at 6-month post-intervention. DISCUSSION: Reducing SB and increasing light-intensity PA plays an important, yet often undervalued role in the health and well-being of PCS. This study will create a unique distance-based platform that can be used by clinical and community-based organizations as a low-cost, supportive care tool to improve health outcomes for PCS.

Associations of light physical activity, moderate-to-vigorous physical activity and sedentary behavior with quality of life in men on androgen deprivation therapy for prostate cancer: a quantile regression analysis.

To examine associations of physical activity (PA) and sedentary time (SED) with quality of life (QoL) in men on androgen deprivation therapy (ADT) for prostate cancer. A pooled analysis of 106 men on ADT was conducted. PA and SED were assessed using accelerometers. The Functional Assessment of Cancer Therapy (FACT) was used to assess self-reported QoL. Quantile regression examined the associations of QoL with PA and SED. Total time spent in SED was positively associated with FACT-General at the 50th (p = 0.010) and 75th percentile (p = 0.022). SED in ≥ 30-min bouts was inversely associated with FACT-General at the 50th  (p = 0.025) and 75th percentile (p = 0.029). Breaks in SED were positively associated with physical well-being at the 75th percentile (p = 0.004). Light-intensity PA was positively associated with FACT-Prostate at the 25th percentile (p = 0.020). SED and PA were associated with QoL outcomes, but time in each varied across men reporting the poorest QoL compared to those in the highest QoL distributions.

Mediation by coping style in the association between stressful life events and depressive symptoms in young adults.

PURPOSE: The association between stressful life events and depressive symptoms is well-established, but the role of coping style in this association is less clear. We examined whether problem-focused, emotion-focused or avoidant coping style mediated and/or moderated the association in young adults. METHODS: Data were drawn from a 20-year longitudinal study that included 1294 students' age 12-13 years recruited in 1999-2000 from ten high schools in Montreal, Canada. Herein we report an analysis that included 782 participants aged 24 years on average with data on covariates collected at age 20. Using VanderWeele's four-way decomposition approach, the total effect of stressful life events on depressive symptoms considering coping styles was decomposed into four components: moderation only, mediation only, mediated interaction, no mediation or moderation. RESULTS: We observed mediation only by emotion-focused coping ([Formula: see text](95%CI) = 0.15(0.04, 0.24)) suggestive that individuals who experienced more stressful life events also reported greater use of emotion-focused coping and higher levels of depressive symptoms. We found moderation only by problem-focused coping ([Formula: see text](95%CI) = - 1.51(- 2.40, - 0.53)) and by emotion-focused coping ([Formula: see text](95%CI) = 1.16(0.57, 1.69). These results suggest that individuals reporting more problem-focused coping experienced fewer depressive symptoms after exposure to stressful life events; those reporting more emotion-focused coping experienced more depressive symptoms. Avoidant coping did not mediate or moderate the association between stressful life events and depressive symptoms. CONCLUSION: Interventions that aim to reduce depressive symptoms in young adults who experience stressful life events may need to reinforce problem-focused coping and minimize emotion-focused coping strategies.

Description of sport participation profiles and transitions across profiles during adolescence.

Few studies describe sport participation profiles in the general population using multiple characteristics. Therefore, the objective of this study was to identify sport participation profiles during adolescence and to describe transitions across profiles from grades 5 to 12 (age 10 to 18 years). We used data from 916 participants (55% girls; age 10-12 years at inception) of the Monitoring Activities of Teenagers to Comprehend their Habits (MATCH) study. Participants self-reported involvement in 36 organized and unorganized physical activities three times/year from grades 5 to 12 (24 data collection cycles; 2011-2018). At each school grade, we derived four categorical variables of sport involvement: number of organized sports, number of unorganized activities, weekly sessions, and number of year-round activities. To identify sport participation profiles, we used latent class analysis at each grade. To characterize transitions between sport participation profiles across grades, we used latent transition analysis. Five distinct sport participation profiles emerged: "non-participants", "unorganized activities only", "single-sport low frequency", "single sport high frequency", and "multi-sport". Only "multi-sport" participants were unlikely to be classified as "non-participants" over time. Encouraging multi-sport participation might help protect against later non-participation. This study helps identify important times to intervene for improving physical activity levels.

"Your Body Is Not At All Where You Left It": Adolescent and Young Adult Cancer Survivors' Experiences Transitioning Back Into Physical Activity After Treatment.

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 (Mage = 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.
