Patient and professional perspectives on physical activity promotion in routine cancer care: a qualitative study.

BACKGROUNDS: Physical activity is associated with many benefits in reducing cancer symptoms and treatments side effects. Yet, studies consistently show that knowledge about physical activity is under-promoted among people diagnosed with cancer. Therefore, we aimed to contribute to filling this gap by ascertaining patient and professional perspectives regarding physical activity promotion. METHODS: This study took place in Montreal, Canada. We conducted individual, semi-structured interviews with cancer patients who participated in a physical activity program and professionals working in the healthcare system. Participants had to be aged over 18 years, be able to communicate verbally in either English or French, and consent to an audio-recorded interview. A hybrid deductive-inductive approach to content analysis was applied to analyze interview transcripts using Dedoose and Microsoft Excel software. RESULTS: Our sample comprised 21 patients (76.2% women) and 20 professionals (80% women). We identified 24 factors (barriers, facilitators, and improvement suggestions) influencing physical activity promotion across organizational, community, and social levels. Results suggest that to improve physical activity promotion in cancer care, it is necessary to showcase exercise specialists as a healthcare resource, to champion for this change within health organizations, to develop partnerships between public and private sectors of the health and fitness industries, and to reassess social norms concerning cancer survivorship and treatment. CONCLUSION: These findings shed light on the gaps and the bright lights in physical activity promotion for people diagnosed with cancer across numerous levels.

Basic Psychological Need Satisfaction as Correlates of Physical Activity Trajectories During Adolescence.

This analysis aimed to (1) identify longitudinal joint trajectories of participation in organized and unorganized physical activity contexts, and level of daily moderate-to-vigorous physical activity (MVPA) and (2) assess whether basic psychological need satisfaction during adolescence differentiates between membership in different physical activity trajectories. Participants (n = 888; 56% girls) reported their involvement in 36 different physical activities, level of MVPA, and their perceived satisfaction of competence, autonomy, and relatedness satisfaction in physical activity up to three times per year, over 8 years (from ages 10 to 17 years). Group-based multi-trajectory models were used to identify longitudinal joint trajectories of physical activity participation. We estimated a multinomial logistic regression model for membership in a physical activity trajectory by including individual-level intercepts and slopes for each psychological need obtained using mixed models over the 24 cycles modelized as natural cubic splines. Five longitudinal trajectory groups emerged: Non-participants, Dropouts, Active in unorganized physical activities, Active in organized physical activities, and Active through a variety of activities. Relative to Non-participants, we identify a dose-response relationship in baseline competence and membership in the higher active trajectory groups. In addition, a positive change in competence in early adolescence predicted membership in all three Active trajectory groups.

Identification of distinct physical activity profiles through adolescence: a longitudinal qualitative description study.

Introduction: We aimed to better understand longitudinal physical activity experiences among initially active adolescents and to identify and describe distinct physical activity profiles. Methods: A sample of 23 physically active participants [52% female; mean age = 12.2 (0.6) years at study inception] were selected from the MATCH study to take part in this nested qualitative descriptive study. Participants were interviewed once a year for six years. Following individual-level analyses, profiles were identified based on similarity of longitudinal experiences. Results: Four profiles captured participants' experiences: Independents (those who progressively seek activities that cater to their pursuit of autonomy); Multitaskers (those who participate in many different sports as an integral part of their lifestyle); Specialists (those who are dedicated to becoming the best they can be at one sport); Undecided (those who take part in physical activity to occupy time). Discussion: The exploration of longitudinal physical activity experiences led to the identification of distinct profiles that could be targets for tailored interventions, theory development, and participation models.

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.

"In My Mind, It Was Just Temporary": A Qualitative Study of the Impacts of Cancer on Men and Their Strategies to Cope.

Individuals who are diagnosed and treated for cancer use a variety of strategies to manage its impacts. However, there is currently a lack of research on men's experience with managing cancer impacts, which is necessary to better support them throughout the cancer care continuum. This study explored the experience of men diagnosed with cancer, focusing on the impacts of the illness and its treatment and men's strategies to cope. A qualitative descriptive design was used. Thirty-one men (Mage = 52.7 [26-82] years) diagnosed with various cancer types were recruited to take part in individual telephone interviews (n = 14) or online focus groups (n = 17) addressing the impacts of cancer and strategies they used to cope with these impacts. Directed content analysis was performed, using Fitch's (2008) supportive care framework to guide the analysis. Cancer impacts and strategies used to cope were classified into six categories: physical, psychological, interpersonal, informational, practical, and spiritual. Results indicate that the cancer experience is diverse and multifaceted rather than homogeneous. Medical and supportive care services could be more effectively personalized to meet the diversity of men's needs by adopting a comprehensive and holistic approach to supportive care. Working in partnership with patients, it appears promising to recognize and identify men's needs and match them to appropriate resources to provide truly supportive care.

Perceived autonomy support from healthcare professionals and physical activity among breast cancer survivors: A propensity score analysis.

The majority of women treated for breast cancer are physically inactive although physical activity (PA) could attenuate many adverse effects of cancer and treatment. Autonomy support from healthcare professionals may improve PA initiation, adherence and maintenance. This study aimed to determine, using a causal inference approach, whether or not perceived autonomy support (PAS) from healthcare professionals is associated with light, moderate, and vigorous intensity PA among women treated for breast cancer. Data were drawn from the longitudinal study "Life After Breast Cancer: Moving On" (n = 199). PAS was measured with the Health Care Climate Questionnaire and PA was assessed using GT3X triaxial accelerometers. Associations between PAS and PA were estimated with linear regressions and adjusted estimations were obtained using propensity score-based inverse probability of treatment weights (IPTW). Results reveal no association between PAS and PA of light ([Formula: see text](95%CI) = -0.09 (-0.68, 0.49)), moderate ([Formula: see text] (95%CI) = -0.03 (-0.17, 0.11)), or vigorous ([Formula: see text](95%CI) = 0.00 (-0.03, 0.02)) intensity. Different forms of engagement and support by healthcare professionals should be explored to identify the best intervention targets to encourage women to adopt and maintain regular PA in the cancer continuum.

Milestones and turning points in the experience of physical activity throughout cancer care: a qualitative study to inform physical activity promotion.

PURPOSE: Physical activity (PA) is an important supportive care strategy to manage cancer and treatment-related side effects, yet PA participation is low among people diagnosed with cancer. This study examined patients', health professionals', and managers' perspectives on PA throughout cancer care to glean implications for PA promotion. METHODS: Random selection and purposeful sampling methods allowed for the recruitment of 21 patients (76.2% women) and 20 health professionals and managers (80% women) who participated in individual semi-structured interviews. Interview questions explored facilitators and barriers to PA participation and promotion across the cancer care continuum. Interviews were audio-recorded and transcribed. Then, qualitative thematic analysis was performed. RESULTS: The analysis produced five main themes describing milestones in PA participation throughout cancer care: (1) Getting Started, (2) Discovering PA Resources, (3) Taking Action, (4) Striving for Change, and (5) Returning to a "New Normal." The sub-themes underscored turning points, i.e., tasks and challenges to PA participation that had to be overcome at each milestone. Achieving milestones and successfully navigating turning points were dependent on clinical, social, and community factors. CONCLUSION: Cancer patients appear to progress through a series of milestones in adopting and maintaining PA throughout cancer care. Intervention strategies aimed at promoting PA could test whether support in navigating turning points could lead to greater PA participation. These findings require replication and extension, specifically among patients who are men, younger adults, and culturally diverse.

Assessing real-world implementability of a multimodal group-based tele-prehabilitation program in cancer care: a pragmatic feasibility study.

Introduction: Multimodal prehabilitation is intended to optimize a patient's mental and physical health prior to surgery. Most multimodal prehabilitation interventions are delivered on a one-on-one format, which may limit benefits associated with social interactions that can be achieved in a group context, and are delivered in-person, which may limit the accessibility. The purpose of this study was to develop a group-based, multimodal, tele-prehabilitation intervention for individuals diagnosed with cancer (iACTIF) and assess its implementability in a "real-world" clinical setting by measuring feasibility, acceptability, fidelity, and preliminary effects. Methods: A prospective, single-group, pragmatic feasibility study was conducted with assessments at baseline, pre-surgery, and 12-weeks post-surgery. iACTIF consisted of three 90-min live videoconference sessions per week, including exercise and educational components. Descriptive statistics were used to document feasibility, acceptability, and fidelity indicators. Paired t-test, Wilcoxon test, and Cohen's D-test were conducted to assess changes in health-related outcomes. Results: A total of 25 participants (mean age ± SD= 60.2 ± 14.0) were recruited. The feasibility assessment revealed a low referral rate (31.4%) and a high study retention (98%) and program attendance [session attended/possible session] (70.2%), with a prehabilitation window of 32.7 days (SD= 20.9, median= 28). Acceptability was high (84%-100%) according to satisfaction, utility and safety, delivery modality, and intention to continue physical activity and to recommend iACTIF to a relative. Pre-post-intervention assessments suggest positive changes on physical functional capacity based on the 2-min step test (mean difference= +18.9 steps, p=0.005), the 30-s sit-to-stand (mean difference= +1.1 repetition, p=0.011), and volume of moderate intensity physical activity per week (mean difference= +104.8 min, p<0.001). Fidelity was supported by conformity and coherence, with only minimal adjustments required to meet participants' needs. Discussion: iACTIF implementability in a "real-world" clinical setting is promising, and preliminary outcomes suggest moderate benefits on physical health and small increase in mental health indicators.

Barriers and facilitators of supportive care access and use among men with cancer: a qualitative study.

PURPOSE: Men diagnosed with cancer are underrepresented in existing supportive care programming and related research, with preliminary indications that men face unique challenges in accessing and engaging with such services. This study aims to identify barriers and facilitators related to the supportive care service access and use among men diagnosed with cancer. METHODS: From March to May 2021, thirty-one Quebec men (Mage = 52.7, range:(26-82 years) diagnosed with various cancer types were recruited to take part in individual telephone interviews (n = 14) or online focus groups (n = 17) addressing experiences of cancer supportive care services. Content analysis of qualitative data was performed. RESULTS: Barriers and facilitators to men's supportive care access and use were grouped into four categories: (1) alignment between services and men's needs and preferences; (2) delivery of services in an accessible, inclusive, and responsive way; (3) communication and promotion of services in ways that are acceptable, appealing, and attractive to men; and (4) social norms and perceptions of gender and masculinity affecting men's perceptions of and engagement with services. CONCLUSIONS: Barriers and facilitators influencing access and use of supportive care services in men are numerous and diverse. These findings may inform the development of new and the adaptation of current supportive care strategies to better address men's needs and preferences after a cancer diagnosis. IMPLICATIONS FOR CANCER SURVIVORS: Increased adequacy of services tailored to men's needs and preferences, with an emphasis on supporting men to take an active role in their recovery, could improve access and adherence to care. Services adopting a more integrated, patient-centered, and holistic approach to service delivery could positively impact the cancer care trajectory and health outcomes of men. Larger systemic changes may be needed to support men in engaging in currently existing activities and services.

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.

Longitudinal Associations Between Body-Related Self-Conscious Emotions and Weight Control Status During Adolescence.

PURPOSE: Half of adolescents are trying to change their weight and body-related self-conscious emotions may influence these intentions. We estimated associations between body-related shame, guilt, embarrassment, envy, authentic pride, and hubristic pride and weight control status (trying to maintain, lose, or gain weight) throughout adolescence in girls and boys. METHODS: Six annual cycles of self-administered questionnaires were collected from age 12-17 in the Monitoring Activities of Teenagers to Comprehend their Habits (MATCH) study (n = 776). Average associations over all cycles were estimated with generalized estimating equations to describe the relationship between emotions (predictors) and weight control status (outcome). To explore the impact of changes in emotions on weight control status, fixed effects logistic regressions were used. Separate models were conducted for each emotion and for boys and girls. RESULTS: On average, boys and girls with higher scores for negative emotions (shame, guilt, embarrassment and, exclusively among girls, envy) had higher odds of trying to lose weight. Higher scores for positive emotions (authentic and hubristic pride) were associated with lower odds of trying to lose weight among girls. Higher scores for authentic pride were associated with trying to gain weight among boys. Girls with increases in any of the negative emotions presented higher odds of trying to lose weight. Girls with increases in hubristic pride had increased odds of trying to maintain weight. DISCUSSION: Body-related self-conscious emotions may be promising healthy-weight intervention targets as they represent important predictors of weight control status, particularly in girls.

Pet ownership and lifestyle behaviours of immunosuppressed individuals and their relatives in the context of COVID-19 pandemic.

The COVID-19 pandemic and containment measures will likely have a detrimental impact on immunosuppressed individuals' lifestyle behaviours. Increasing evidence suggests that pet ownership is positively associated with healthier lifestyle. Yet, no study has investigated the potential benefits of pet ownership on lifestyle behaviours of immunosuppressed individuals, a population at increased risk of COVID-19 complications. This study aims to examine 1) changes in light, moderate and vigorous intensity physical activity (LPA, MPA, VPA), sedentary time (SED), and sleep duration, assessed by comparing "before COVID-19 pandemic" and "past 7 days" (i.e., current, during pandemic) self-reported behaviours in immunosuppressed individuals and their relatives; 2) to assess if changes in lifestyle behaviours are associated with pet ownership status and whether age is a moderator of these associations. A convenience sample of 132 participants (65.2% female, 41.3% ≥55 years of age) provided self-reported LPA, MPA, VPA (days/week), SED and sleep (min/day) and pet ownership status using an online questionnaire (May-August 2020). Descriptive analyses, paired T-tests, Cohen's d effect size and linear regressions were conducted. Results show that participants reported a decrease in VPA (-0.56 days/week, d = 0.34; p < 0.01) and an increase in SED (106.79 min/day, d = -0.81; p < 0.01). Stratified analysis revealed that having at least one dog, compared to not owning pets, is associated with a reduced decline in LPA, MPA and VPA and an increase in sleep in participants aged < 55 years old only. Having a dog appears to be positively associated with healthy lifestyle behaviours in younger and middle age immunosuppressed individuals.

The Association between Change in Lifestyle Behaviors and Mental Health Indicators in Immunosuppressed Individuals during the COVID-19 Pandemic.

Little is known on how changes in lifestyle behaviors affect mental health among immunosuppressed individuals who observed stricter physical and social distancing measures due to higher risk of complications during the COVID-19 pandemic. This study examines the association between changes in moderate-to-vigorous physical activity (MVPA), sedentary time (ST) and sleep duration following COVID-19 outbreak on mental health indicators of immunosuppressed individuals and their relatives. Participants (n = 132) completed an online questionnaire between May and August 2020. Linear regressions were conducted to assess the associations between an increase or decrease in lifestyle behaviors and mental health indicators. Individuals with decreased MVPA and increased ST experienced higher distress, anxiety and depressive symptoms. Those who reported an increase or decrease in sleep had higher levels of stress, distress and depressive symptoms. Decreases in sleep was associated with higher anxiety symptoms. Lifestyle behaviors in the context of a stressful life event such as the COVID-19 pandemic may impact mental health indicators of immunosuppressed individuals and their relatives.

Flourishing or physical activity?: Identifying temporal precedence in supporting the transition to university.

Objective: Flourishing is a mental health indicator that helps students function optimally, which may be important for first-year university students. Physical activity (PA) also contributes to optimal functioning, yet the flourishing and PA relationship has received little attention. The bidirectional relationships between flourishing and meeting moderate-to-vigorous PA (MVPA) guidelines were assessed during the first year of university. Methods: First-year university students completed surveys (September [T1], March [T2]). Reciprocal effects were examined in a cross-lagged path model. Results: Over 40% of the sample was not meeting MVPA guidelines at T1 or T2. Controlling for sex, higher T1 flourishing was associated with higher odds of meeting T2 MVPA guidelines. T1 MVPA did not predict T2 flourishing. Conclusions: The findings provide preliminary evidence that flourishing may support meeting MVPA guidelines for first-year students. Given low rates of meeting guidelines, flourishing and PA could be targeted to foster MVPA, supporting a healthy university transition.

Body image self-conscious emotions get worse throughout adolescence and relate to physical activity behavior in girls and boys.

Body image is a commonly-reported factor perpetuating declines in physical activity levels during adolescence. However, the evidence is predominantly qualitative, cross-sectional, and focused on girls. Furthermore, the affective dimension of body image has been overlooked compared to the perceptual (e.g., misrepresentations of body size) and cognitive (e.g., dissatisfaction) dimensions. Affective body image includes a range of self-conscious emotions including guilt, shame, envy, embarrassment, and authentic and hubristic pride. This study examined (i) body-related self-conscious emotions over time, and (ii) associations between body-related emotions and physical activity over five years during early-to-mid adolescence. Potential gender differences were also explored. Self-report data for this study were collected once a year over 5 years as part of the MATCH study. The main analyses involved mixed-effects modeling. Participants (n = 776, 55.8% girls) initially aged 12.6 (SD = 0.6) years who provided data on at least one occasion were included in the analysis. Girls reported higher body-related guilt, shame, envy, and embarrassment than boys, and boys reported higher hubristic pride than girls. Over five years from early to mid-adolescence, body-related shame, guilt, envy, and embarrassment significantly increased for boys and girls, authentic pride did not change, and hubristic pride increased for girls only. Controlling for gender and puberty status, body-related guilt, shame, and embarrassment were negatively, and body-related authentic and hubristic pride were positively, associated with physical activity over time. Body-related envy was not significantly related to physical activity. These findings suggest that adolescents express greater negative body-related self-conscious emotions over time. Since these were negatively related to physical activity, interventions focused on reducing negative body-related emotions and enhancing positive body-related emotions may be valuable in adolescence to help curb declining physical activity.

Developing practice guidelines to integrate physical activity promotion as part of routine cancer care: A knowledge-to-action protocol.

BACKGROUND: Cancer is a leading cause of disease burden worldwide and the first cause of mortality in Canada with 30.2% of deaths attributable to cancer. Given aging of the population and the improvement of prevention and treatment protocols, the number of cancer survivors is steadily increasing. These individuals have unique physical and mental health needs some of which can be addressed by integrating physical activity promotion into ongoing and long-term care. Despite the benefits of being active, delivery of PA programs for cancer patients in both clinical and community settings remains challenging. This knowledge-to-action protocol-called Kiné-Onco-aims to develop a practice guideline for the delivery, implementation, and scaling-up of cancer-specific physical activity promotion programs and services in clinical and community settings located in Québec, Canada. METHOD: The Kiné-Onco project involves knowledge synthesis of scientific and grey literature to establish the benefits and added value of physical activity for cancer patients and survivors, describes current practices in delivering physical activity programs, analyses quantitative data from electronic health records (EHR) of patients participating in a novel hospital-based physical activity program, collects and analyses qualitative data from patients and healthcare providers interviews about lived experience, facilitators, and barriers to physical activity promotion, outlines deliberative workshops among multidisciplinary team members to develop implementation guidelines for physical activity promotion, and summarizes a variety of knowledge transfer and exchange activities to disseminate the practice guidelines. DISCUSSION: This paper describes the protocol for a knowledge-to-action project aimed at producing and sharing actionable evidence. Our aim is that physical activity promotion programs and services be scaled up in such a way as to successfully integrate physical activity promotion throughout cancer treatment and survivorship in order to improve the physical and mental health of the growing population of individuals having received a cancer diagnosis.

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.

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.

Identifying priorities for sport and physical activity research in Canada: an iterative priority-setting study.

BACKGROUND: There is a need for better alignment between research on sport and physical activity and the needs of those who are in a position to implement the findings. To facilitate advancement and alignment, we identified the top research priorities of sport and physical activity knowledge users from various sectors. METHODS: For this priority-setting study, we used an iterative process of data collection and analysis. Sport and physical activity knowledge users from multiple sectors participated in a workshop (September 2019), which included small working group exercises followed by large-group syntheses leading to the identification of issues that required better understanding. We then sent an online questionnaire to participants for content validation and interim prioritization, to reduce the number of priorities (December 2019 to January 2020). A new questionnaire containing a shortened list of research priorities was sent to an expanded group of respondents to further streamline the list of priorities (January-March 2020). RESULTS: The 24 workshop participants identified 68 issues, of which 21 were retained by the 18 participants in the interim priority-setting questionnaire. The final prioritization questionnaire was completed by 33 stakeholder groups; this step produced a final list of 8 top research priorities. The final priorities identified for sport and physical activity research related to financial support, suboptimal promotion, dropout, best interventions, participation among Indigenous populations, volunteer engagement, safe and inclusive experiences, and knowledge exchange. INTERPRETATION: The 8 priorities identified in this study provide guidance to Canadian sport and physical activity researchers. Research efforts on these priorities will reflect pressing issues as identified by representatives of all sport and physical activity sectors.

Quarantots, quarankids, and quaranteens: how research can contribute to mitigating the deleterious impacts of the COVID-19 pandemic on health behaviours and social inequalities while achieving sustainable change.

The adoption and maintenance of healthy behaviours including age-appropriate amounts of physical activity, limited sedentary and screen time, and healthy eating are the foundations for youth development and thriving. In reviewing extant evidence, we observe that the COVID-19 pandemic has been associated with marked reductions in physical activity, increased sedentary and screen time, and increased food intake and unhealthy snacking. Deleterious effects in movement behaviours appear to be more pronounced among vulnerable groups and food insecurity has become more widespread. To contribute to mitigating these impacts, we advocate for strengthened evidence-based public health. Towards this end, ongoing surveillance should be intensified and augmented with additional indicators of social inequalities. More importantly, substantial efforts must be devoted to developing, implementing, and evaluating complex interventions aimed at equitably promoting recommended 24-hour movement behaviours and healthy eating guidelines in home, childcare, school, and neighbourhood settings.

RéSUMé: L'adoption et le maintien de saines habitudes de vie telles des niveaux d'activité physique appropriés pour l'âge, des durées limitées d'activités sédentaires et de temps d'écran, de même qu'une alimentation saine, sont des piliers pour le développement et l'épanouissement des enfants et des jeunes. Après avoir recensé les écrits disponibles, nous constatons que la pandémie de COVID-19 a été associée avec une réduction marquée de l'activité physique, une augmentation de la durée des activités sédentaires et du temps d'écran et une augmentation de la consommation de nourriture et de collations sucrées. Les effets délétères sur les comportements d'activité physique semblent plus prononcés parmi les groupes vulnérables et l'insécurité alimentaire est davantage répandue. Afin de contribuer à atténuer ces impacts, nous proposons le renforcement d'une santé publique fondée sur les données probantes. Nous recommandons une intensification et une bonification des activités de surveillance par l'ajout de nouveaux indicateurs pour mesurer les inégalités sociales de santé. De plus, des efforts considérables doivent être investis dans le développement, l'implantation et l'évaluation d'interventions complexes visant à promouvoir équitablement les directives canadiennes relatives au mouvement sur 24 heures et les saines habitudes alimentaires dans les familles, milieux de garde, écoles et quartiers résidentiels.
