Prioritizing a research agenda on built environments and physical activity: a twin panel Delphi consensus process with researchers and knowledge users.

BACKGROUND: The growth of urban dwelling populations globally has led to rapid increases of research and policy initiatives addressing associations between the built environment and physical activity (PA). Given this rapid proliferation, it is important to identify priority areas and research questions for moving the field forward. The objective of this study was to identify and compare research priorities on the built environment and PA among researchers and knowledge users (e.g., policy makers, practitioners). METHODS: Between September 2022 and April 2023, a three-round, modified Delphi survey was conducted among two independent panels of international researchers (n = 38) and knowledge users (n = 23) to identify similarities and differences in perceived research priorities on the built environment and PA and generate twin 'top 10' lists of the most important research needs. RESULTS: From a broad range of self-identified issues, both panels ranked in common the most pressing research priorities including stronger study designs such as natural experiments, research that examines inequalities and inequities, establishing the cost effectiveness of interventions, safety and injuries related to engagement in active transportation (AT), and considerations for climate change and climate adaptation. Additional priorities identified by researchers included: implementation science, research that incorporates Indigenous perspectives, land-use policies, built environments that support active aging, and participatory research. Additional priorities identified by knowledge users included: built environments and PA among people living with disabilities and a need for national data on trip chaining, multi-modal travel, and non-work or school-related AT. CONCLUSIONS: Five common research priorities between the two groups emerged, including (1) to better understand causality, (2) interactions with the natural environment, (3) economic evaluations, (4) social disparities, and (5) preventable AT-related injuries. The findings may help set directions for future research, interdisciplinary and intersectoral collaborations, and funding opportunities.

Guidelines for assessment of affect-related constructs.

Research on affect-related constructs as determinants of health behavior is increasing. The Affect and Health Behavior Framework (AHBF) provides a schematic structure to label, organize, and integrate affect-related constructs. To further facilitate research and theory development in health behavior science, the purpose of the present paper is to provide a critical review and guidelines for assessment of the affect-related constructs in the AHBF. The paper is organized based on the categories of constructs in the AHBF: Affective response to health behavior, incidental affect, affect processing, and affectively charged motivation. Future research should work toward parsing constructs where possible as well as identifying overlap. Researchers are advised to consider conceptual underpinnings and methodological nuances when assessing affect-related constructs in order to build a cumulative science of affective determinants of health behavior.

Supporting physical activity for mobility in older adults with mobility limitations (SuPA Mobility): study protocol for a randomized controlled trial.

BACKGROUND: Limited mobility in older adults consistently predicts both morbidity and mortality. As individuals age, the rates of mobility disability increase from 1.0% in people aged 15-24 to 20.6% in adults over 65 years of age. Physical activity can effectively improve mobility in older adults, yet many older adults do not engage in sufficient physical activity. Evidence shows that increasing physical activity by 50 min of moderate intensity physical activity in sedentary older adults with mobility limitations can improve mobility and reduce the incidence of mobility disability. To maximize the healthy life span of older adults, it is necessary to find effective and efficient interventions that can be delivered widely to prevent mobility limitations, increase physical activity participation, and improve quality of life in older adults. We propose a randomized controlled trial to assess the effect of a physical activity health coaching intervention on mobility in older adults with mobility limitations. METHODS: This randomized controlled trial among 290 (145 per group) community-dwelling older adults with mobility limitations, aged 70-89 years old, will compare the effect of a physical activity health coaching intervention versus a general healthy aging education program on mobility, as assessed with the Short Physical Performance Battery. The physical activity health coaching intervention will be delivered by exercise individuals who are trained in Brief Action Planning. The coaches will use evidence-based behavior change techniques including goal-setting, action planning, self-monitoring, and feedback to improve participation in physical activity by a known dose of 50 min per week. There will be a total of 9 health coaching or education sessions delivered over 26 weeks with a subsequent 26-week follow-up period, wherein both groups will receive the same duration and frequency of study visits and activities. DISCUSSION: The consequences of limited mobility pose a significant burden on the quality of life of older adults. Our trial is novel in that it investigates implementing a dose of physical activity that is known to improve mobility in older adults utilizing a health coaching intervention.

Use of Electronic Ecological Momentary Assessment Methodologies in Physical Activity, Sedentary Behavior, and Sleep Research in Young Adults: Systematic Review.

BACKGROUND: Recent technological advances allow for the repeated sampling of real-time data in natural settings using electronic ecological momentary assessment (eEMA). These advances are particularly meaningful for investigating physical activity, sedentary behavior, and sleep in young adults who are in a critical life stage for the development of healthy lifestyle behaviors. OBJECTIVE: This study aims to describe the use of eEMA methodologies in physical activity, sedentary behavior, and sleep research in young adults. METHODS: The PubMed, CINAHL, PsycINFO, Embase, and Web of Science electronic databases were searched through August 2022. Inclusion criteria were use of eEMA; sample of young adults aged 18 to 25 years; at least 1 measurement of physical activity, sedentary behavior, or sleep; English language; and a peer-reviewed report of original research. Study reports were excluded if they were abstracts, protocols, or reviews. The risk of bias assessment was conducted using the National Heart, Lung, and Blood Institute's Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Screening, data extraction, and risk of bias assessments were conducted by independent authors, with discrepancies resolved by consensus. Descriptive statistics and narrative synthesis were used to identify overarching patterns within the following categories guided by the Checklist for Reporting Ecological Momentary Assessments Studies: study characteristics, outcomes and measures, eEMA procedures, and compliance. RESULTS: The search resulted in 1221 citations with a final sample of 37 reports describing 35 unique studies. Most reports (28/37, 76%) were published in the last 5 years (2017-2022), used observational designs (35/37, 95%), consisted of samples of college students or apprentices (28/35, 80%), and were conducted in the United States (22/37, 60%). The sample sizes ranged from 14 to 1584 young adults. Physical activity was measured more frequently (28/37, 76%) than sleep (16/37, 43%) or sedentary behavior (4/37, 11%). Of the 37 studies, 11 (30%) reports included 2 movement behaviors and no reports included 3 movement behaviors. eEMA was frequently used to measure potential correlates of movement behaviors, such as emotional states or feelings (25/37, 68%), cognitive processes (7/37, 19%), and contextual factors (9/37, 24%). There was wide variability in the implementation and reporting of eEMA procedures, measures, missing data, analysis, and compliance. CONCLUSIONS: The use of eEMA methodologies in physical activity, sedentary behavior, and sleep research in young adults has greatly increased in recent years; however, reports continue to lack standardized reporting of features unique to the eEMA methodology. Additional areas in need of future research include the use of eEMA with more diverse populations and the incorporation of all 3 movement behaviors within a 24-hour period. The findings are intended to assist investigators in the design, implementation, and reporting of physical activity, sedentary behavior, and sleep research using eEMA in young adults.

The Development of a Hypertension Prevention and Financial-Incentive mHealth Program Using a "No-Code" Mobile App Builder: Development and Usability Study.

BACKGROUND: Regular physical activity (PA) is a key lifestyle component for hypertension prevention. Previous studies have shown that mobile health (mHealth) apps can be an effective tool for improving PA behaviors. However, adherence to and poor engagement with these apps is a challenge. A potential solution to overcome this challenge may be to combine financial incentives with innovative behavior theory, such as the Multiprocess Action Control (M-PAC) framework. Currently, there is a lack of PA financial incentive-driven M-PAC mHealth programs aimed at hypertension prevention. OBJECTIVE: We aimed to describe the process of developing an 8-week mHealth PA and financial-incentive hypertension education program (Healthy Hearts) and to evaluate usability of the Healthy Hearts program. METHODS: The first 2 stages of the Integrate, Design, Assess, and Share framework were used to guide the development of the Healthy Hearts program. The development process consisted of 2 phases. In phase 1, the research team met to discuss implementing the M-PAC framework to adopt an existing web-based hypertension prevention program to a mobile app. The app was developed using a no-code app development platform, Pathverse (Pathverse Inc), to help decrease overall development time. In phase 2, we created a prototype and conducted usability testing to evaluate lesson 1 of the Healthy Hearts program to further enhance the user experience. We used semistructured interviews and the mHealth App Usability Questionnaire to evaluate program acceptability and usability. RESULTS: Intervention development among the research team successfully created an 8-week financial-incentive hypertension education program for adults aged 40-65 years who did not currently meet the Canadian Physical Activity Guidelines (<150 minutes of moderate to vigorous PA per week). This program lasted 8 weeks and comprised 25 lessons guided by the M-PAC framework. The program used various behavior change techniques to further support PA adherence. Usability testing of the first lesson was successful, with 6 participants recruited for 2 rounds of testing. Feedback was gathered to enhance the content, layout, and design of the Healthy Hearts program to prepare the mHealth program for feasibility testing. Results of round 1 of usability testing suggested that the content delivered in the lessons was long. Therefore, the content was divided into multiple lessons before round 2 of usability testing, where feedback was only on design preferences. A minimum viable product was created with these results. CONCLUSIONS: The iterative development process and the usability assessments suggested by the Integrate, Design, Assess, and Share framework enabled participants to provide valuable feedback on the content, design, and layout of the program before advancing to feasibility testing. Furthermore, the use of the "no-code" app development tool enabled our team to rapidly make changes to the app based on user feedback during the iterative design process.

Effects of Mobile-Based Financial Incentive Interventions for Adults at Risk of Developing Hypertension: Feasibility Randomized Controlled Trial.

BACKGROUND: Hypertension is the leading modifiable risk factor for cardiovascular disease and mortality. Adopting lifestyle modifications, like increasing physical activity (PA), can be an effective strategy in blood pressure (BP) control, but many adults do not meet the PA guidelines. Financial incentive interventions have the power to increase PA levels but are often limited due to cost. Further, mobile health technologies can make these programs more scalable. There is a gap in the literature about the most feasible and effective financial incentive PA framework; thus, pay-per-minute (PPM) and self-funded investment incentive (SFII) frameworks were explored. OBJECTIVE: The aims were to (1) determine the feasibility (recruitment, engagement, and acceptability) of an 8-week mobile-based PPM and SFII hypertension prevention PA program and (2) explore the effects of PPM and SFII interventions relative to a control on the PA levels, BP, and PA motivation. METHODS: In total, 55 adults aged 40-65 years not meeting the Canadian PA guidelines were recruited from Facebook and randomized into the following groups: financial incentive groups, PPM or SFII, receiving up to CAD $20 each (at the time of writing: CAD $1=US $0.74), or a control group without financial incentive. PPM participants received CAD $0.02 for each minute of moderate-to-vigorous PA (MVPA) per week up to the PA guidelines and the SFII received CAD $2.50 for each week they met the PA guidelines. Feasibility outcome measures (recruitment, engagement, and acceptability) were assessed. Secondary outcomes included changes in PA outcomes (MVPA and daily steps) relative to baseline were compared among PPM, SFII, and control groups at 4 and 8 weeks using linear regressions. Changes in BP and relative autonomy index relative to baseline were compared among the groups at follow-up. RESULTS: Participants were randomized to the PPM (n=19), SFII (n=18), or control (n=18) groups. The recruitment, retention rate, and engagement were 77%, 75%, and 65%, respectively. The intervention received overall positive feedback, with 90% of comments praising the intervention structure, financial incentive, and educational materials. Relative to the control at 4 weeks, the PPM and SFII arms increased their MVPA with medium effect (PPM vs control: η2p=0.06, mean 117.8, SD 514 minutes; SFII vs control: η2p=0.08, mean 145.3, SD 616 minutes). At 8 weeks, PPM maintained a small effect in MVPA relative to the control (η2p=0.01, mean 22.8, SD 249 minutes) and SFII displayed a medium effect size (η2p=0.07, mean 113.8, SD 256 minutes). Small effects were observed for PPM and SFII relative to the control for systolic blood pressure (SBP) and diastolic blood pressure (DBP) (PPM: η2p=0.12, Δmean SBP 7.1, SD 23.61 mm Hg; η2p=0.04, Δmean DBP 3.5, SD 6.2 mm Hg; SFII: η2p=0.01, Δmean SBP -0.4, SD 1.4 mm Hg; η2p=0.02, Δmean DBP -2.3, SD 7.7 mm Hg) and relative autonomy index (PPM: η2p=0.01; SFII: η2p=0.03). CONCLUSIONS: The feasibility metrics and preliminary findings suggest that a future full-scale randomized controlled trial examining the efficacy of PPM and SFII relative to a control is feasible, and studies with longer duration are warranted.

Examining whether affectively-charged motivations predict subsequent affective response during physical activity: An ecological momentary assessment study.

Background: Evidence suggests positive affective response during physical activity increases the likelihood of engaging in and maintaining regular activity exercise in the future. Elucidating antecedents for a positive affective response may help identify intervention strategies to increase activity. Affectively-charged motivations (e.g., desires, urges, dreading) have been posited as proximal antecedents to physical activity but have yet to be examined in terms of their influence on affective response in real-world settings. The current study used ecological momentary assessment (EMA) to examine within-subject effects of pre-physical activity affectively-charged motivation on subsequent affective response during physical activity. Methods: Participants included 56 adults (M = 39.18 years, SD = 11.98; 67.86% female) who completed a 14-day smartphone-based EMA study. Prior to starting physical activity (time t), participants self-initiated an event-contingent EMA survey that assessed affectively-charged motivation for physical activity (i.e., rating scale from "dreading it" to "excited to do it"). EMA surveys prompted during subsequent physical activity (time t + 15 min) assessed affective response (i.e., feeling good-bad, energized-exhausted, thrilled-miserable, interested-bored, and relaxed-nervous). Multi-level linear regression models examined within-subject effects of pre- physical activity affectively-charged motivations on subsequent affective response during physical activity controlling for between-subjects effects of affectively-charged motivation, age, biological sex, time of day, and day of the week. Results: Overall, there were N = 304 physical activity occasions in the analysis (M = 5.43, SD = 3.97). When individuals reported more positive affectively-charged motivation for physical activity than usual before physical activity occasions, they reported feeling more energized (Estimate = 0.22, p < 0.001), good (Estimate = 0.25, p < 0.001), thrilled (Estimate = 0.12, p = 0.02), and interested (Estimate = 0.24, p < 0.001) during subsequent physical activity. Affectively-charged motivation was not associated with feeling more relaxed (Estimate = 0.11, p = 0.13) during subsequent physical activity. Conclusion: Momentary affectively-charged motivations predicted more positive affective response during subsequent physical activity among active adults. Future research can explore potential sources of intraindividual differences in affectively-charged motivations and further examine these associations with future physical activity behavior. To improve positive affective responses, interventions may boost affectively-charged motivations through real-time mobile prompting in naturalistic settings.

Canadian children's and youth's adherence to the 24-h movement guidelines during the COVID-19 pandemic: A decision tree analysis.

PURPOSE: The purpose of this study was to use decision tree modeling to generate profiles of children and youth who were more or less likely to meet the Canadian 24-h movement guidelines during the coronavirus disease-19 (COVID-19) outbreak. METHODS: Data for this study were from a nationally representative sample of 1472 Canadian parents (Meanage = 45.12, SD = 7.55) of children (5-11 years old) or youth (12-17 years old). Data were collected in April 2020 via an online survey. Survey items assessed demographic, behavioral, social, micro-environmental, and macro-environmental characteristics. Four decision trees of adherence and non-adherence to all movement recommendations combined and each individual movement recommendation (physical activity [PA], screen time, and sleep) were generated. RESULTS: Results revealed specific combinations of adherence and non-adherence characteristics. Characteristics associated with adherence to the recommendation(s) included high parental perceived capability to restrict screen time, annual household income of ≥ $100,000, increases in children's and youth's outdoor PA/sport since the COVID-19 outbreak began, being a boy, having parents younger than 43 years old, and small increases in children's and youth's sleep duration since the COVID-19 outbreak began. Characteristics associated with non-adherence to the recommendation(s) included low parental perceived capability to restrict screen time, youth aged 12-17 years, decreases in children's and youth's outdoor PA/sport since the COVID-19 outbreak began, primary residences located in all provinces except Quebec, low parental perceived capability to support children's and youth's sleep and PA, and annual household income of ≤ $99,999. CONCLUSION: Our results show that specific characteristics interact to contribute to (non)adherence to the movement behavior recommendations. Results highlight the importance of targeting parents' perceived capability for the promotion of children's and youth's movement behaviors during challenging times of the COVID-19 pandemic, paying particular attention to enhancing parental perceived capability to restrict screen time.

Changing Sedentary Behavior in the Office: A Randomised Controlled Trial Comparing the Effect of Affective, Instrumental, and Self-Regulatory Messaging on Sitting.

BACKGROUND: Although avoiding sedentary behavior has many health benefits, adults often sit for long periods at work. The purpose of this study was to compare affective attitude, instrumental attitude, and self-regulation messaging interventions on sitting in the workplace. METHODS: Using a cluster randomised controlled trial design, participants (N = 116) were assigned (by workplace) to: (a) instrumental, (b) affective, (c) self-regulation, or (d) control (nutrition information) groups. Measurements were taken online at baseline, 4 weeks, 8 weeks, and 12 weeks post-baseline. The interventions comprised three presentations delivered following baseline, week 4, and week 8 assessments. The primary outcome was self-reported average hours of sitting per day at work (registered trial number: NCT04082624). RESULTS: Controlling for baseline sitting, overall, the affective group sat for less time than the instrumental and self-regulation groups. Also, at week 4, the affective group sat for less time than the instrumental and self-regulation groups and, at week 8, the affective group sat for less time than the self-regulation and control groups. There were no differences between the groups at week 12. CONCLUSIONS: This investigation showed that workplace interventions targeting affective attitude can lead to less sitting time in the short term. Future research should explore additional strategies to minimise sedentary behavior in the long term.

Make Room for Play: An Evaluation of a Campaign Promoting Active Play.

In the context of rising screen time, only a third of Canadian children are achieving adequate amounts of active play, an important source of physical activity. ParticipACTION, a national not-for-profit organization, created the "Make Room for Play" campaign targeting parents with television advertisements depicting how screen time takes away from active play. The advertisements featured children engaging in active play (e.g., jump rope) while a black screen progressively sequesters the room for them to play. This study's purpose was to evaluate the campaign using the hierarchy of effects model, a framework for conceptualizing the impact of mass media campaigns. It was hypothesized that recall would relate to intermediate (e.g., cognitions, self-efficacy) and distal (e.g., parental support) factors. Twenty-six percent of the general population and caregiver samples surveyed (N = 1576) recalled (unaided) the advertisement and 45.9% recalled when prompted. Parental support was significantly higher in those recalling the campaign, p = .009. Twenty-four percent of parents reporting unaided recall (versus 14.0% of those not) tried to engage in active play with their children and 21.2% (versus 12.0%) tried to create opportunities for children to engage in play. Strengths and limitations of mass media approaches targeting active play and screen time are discussed.

Toward a better assessment of perceived social influence: The relative role of significant others on young athletes.

The purpose of this three-study paper was to develop and validate the Perceived Social Influence in Sport Scale-2 (PSISS-2) that aimed to resolve the limitations of PSISS-1 in assessing the relative social influence of significant others in youth sport. In Study 1, a pool of 60 items generated from revisiting a qualitative dataset about significant others of young athletes were examined by two expert panel reviews in terms of content validity, clarity, coverage, and age-appropriateness, leading to the development of 16 items of the PSISS-2. In Study 2, multi-group exploratory structural equation model for PSISS-2 was conducted among 904 young athletes, and the results supported a model comprising positive influence (ie, conditional and unconditional positive influence combined), punishment (ie, conditional negative influence), and dysfunction (ie, unconditional negative influence) as three factors. The goodness of fit of the three-factor model was acceptable and invariant across the coach-, father-, mother-, and teammates-versions of PSISS-2. In support of the criterion validity of PSISS-2, the three factors explained substantial variance of young athletes' perceived competence, effort, enjoyment, and trait anxiety in sport. Study 3 examined the relationship between PSISS-2 factors, psychological need support, and controlling behaviors in a subsample of 452 young athletes, and the findings supported the concurrent validity and discriminant validity of the scale. In conclusion, the data are supportive of PSISS-2. The three factors of the scale (ie, positive influence, punishment, and dysfunction) may form a new framework for understanding and comparing the relative role of significant others in youth sport.

Decomposing the within-person and between-person sources of variation in physical activity-cognition associations for low-active older adults.

OBJECTIVES: To examine within-person and between-person sources of variation in the relationship between physical activity and cognition in older adults participating in a walking program. To explore whether demographic, health and fitness variables, and their interactions with activity, are significant predictors of cognition. DESIGN: Brief longitudinal burst design. PARTICIPANTS: 118 participants (91 females, mean age = 72.81 + 5.24 years). MAIN OUTCOME MEASURES: Cognition, self-reported moderate-to-vigorous walking and self-reported moderate-to-vigorous physical activity were assessed at baseline and 6, 9, 12 and 16 weeks follow-up. Attendance at weekly walks was also recorded. RESULTS: Within-persons, changes in physical activity were related to select measures of executive functioning, with increased activity predictive of better cognition (three of four cognitive functions, p<.05). Between-persons, activity was also associated with cognition (two of four cognitive functions, p<.05). Younger age and higher education were related to better cognition. Interactions of demographic, health, and fitness variables with changes in within-person activity were generally non-significant. CONCLUSION: The results highlight the importance of distinguishing within- from between-person effects in longitudinal analyses of the association between physical activity and cognition. This stringent within-person test of association underscores the potential value of simple physical activity interventions for improving cognitive function.

ParticipACTION after 5 years of relaunch: a quantitative survey of Canadian organizational awareness and capacity regarding physical activity initiatives. / ParticipACTION, cinq ans après sa relance : enquête quantitative sur son rayonnement et sur le pouvoir d'action des organisations au Canada en matière d'initiatives consacrées à l'activité physique.

INTRODUCTION: ParticipACTION is a Canadian physical activity communications and social marketing organization relaunched in 2007. This study assesses the capacity of Canadian organizations to adopt, implement, and promote physical activity initiatives. The four objectives were to compare findings from baseline (2008) and follow-up (2013) with respect to: (1) awareness of ParticipACTION; (2) organizational capacity to adopt, implement and promote physical activity initiatives; (3) potential differences in capacity based on organizational size, sector, and mandate; and (4) assess perceptions of ParticipACTION five years after relaunch. METHODS: In this cross-sectional study, representatives from local, provincial/territorial, and national organizations completed an online survey assessing capacity to adopt, implement, and promote physical activity. Descriptive statistics and one-way analyses of variance were conducted to examine the objectives. RESULTS: Response rate for opening an email survey invitation and consenting to participate was 40.6% (685/1688) and 540 surveys were completed. Awareness of ParticipACTION increased from 54.6% at baseline to 93.9% at follow-up (Objective 1). Findings at both baseline and follow-up reflected good organizational capacity to adopt, implement and promote physical activity (Objective 2) although some varied by organizational sector and mandate (Objective 3). Most respondents reported that ParticipACTION provided positive leadership (65.3%), but there was less agreement regarding ParticipACTION's facilitation of infrastructure (44.0%) or organizational will/motivation (47.1%)(Objective 4). CONCLUSION: Canadian organizations continue to report having good capacity to adopt, implement, and promote physical activity. There was no discernible change in capacity indicators five years after ParticipACTION's relaunch although its broader contribution to the physical activity sector was endorsed.

INTRODUCTION: ParticipACTION est un organisme canadien relancé en 2007 dédié à la communication et au marketing social en matière d'activité physique. Cette étude porte sur le pouvoir d'action des organismes canadiens dans l'adoption, la mise en oeuvre et la promotion des initiatives en ce domaine. Nos objectifs étaient de comparer les résultats de base (2008) avec les résultats de suivi (2013) en ce qui concerne (1) la connaissance de ParticipACTION, (2) la capacité d'un organisme à adopter, à mettre en oeuvre et à promouvoir des initiatives d'activité physique et (3) les différences potentielles en matière de pouvoir d'action d'une organisation en fonction de sa taille, de son secteur et de son mandat ainsi que (4) d'évaluer la perception de ParticipACTION cinq ans après sa relance. MÉTHODOLOGIE: Dans le cadre de cette étude transversale, des représentants d'organismes locaux, provinciaux, territoriaux et nationaux ont rempli un questionnaire en ligne visant à évaluer la capacité de leur organisme à adopter, à mettre en oeuvre et à promouvoir des initiatives d'activité physique. Nous avons utilisé des méthodes de statistique descriptive et des analyses de variance à un facteur pour répondre à nos objectifs. RÉSULTATS: Le taux de réponse correspondant aux personnes ayant ouvert le courriel d'invitation à répondre au sondage et ayant consenti à y participer était de 40,6 % (685/1 688). Au total, 540 questionnaires de sondage ont été remplis. Le taux de connaissance de ParticipACTION, qui se chiffrait à 54,6 % lors de l'étude initiale, avait atteint 93,9 % au moment du suivi (objectif 1). Tant les résultats initiaux que les résultats de suivi ont fait état d'un pouvoir d'action important des organismes dans l'adoption, la mise en oeuvre et la promotion d'initiatives d'activité physique (objectif 2), avec cependant de légères variations en fonction du secteur et du mandat de chaque organisme (objectif 3). La plupart des répondants ont affirmé que ParticipACTION exerçait un leadership positif (65,3 %), mais les avis étaient plus partagés quant à son rôle de conseil aux infrastructures (44,0 %) ou encore de soutien à la motivation organisationnelle (47,1 %) (objectif 4). CONCLUSION: Les organismes canadiens font marque d'un pouvoir d'action important en matière d'adoption, de mise en oeuvre et de promotion d'initiatives d'activité physique. Cependant, cinq ans après la relance de ParticipACTION et malgré une meilleure reconnaissance de sa contribution globale au secteur de l'activité physique, aucun changement notable n'a été relevé dans les indicateurs mesurant le pouvoir d'action des organismes.

Perceptions of organizational capacity to promote physical activity in Canada and ParticipACTION's influence five years after its relaunch: a qualitative study. / Étude qualitative sur les perceptions à propos de la capacité des organisations à promouvoir l'activité physique au Canada et à propos de l'influence de ParticipACTION cinq ans après sa relance.

INTRODUCTION: ParticipACTION is a Canadian physical activity communications and social marketing organization relaunched in 2007. The purpose of this study was to qualitatively investigate organizational capacity for physical activity promotion among Canadian organizations, and the influence of ParticipACTION on capacity five years after relaunch. METHODS: Using a purposive sampling strategy, semi-structured telephone interviews were conducted with 44 key informants representing national, provincial, and local organizations with a mandate to promote physical activity. Interview data were analyzed using a thematic analytic approach. RESULTS: Organizational capacity in terms of partnerships and collaborations, and the general climate for physical activity promotion have improved since ParticipACTION's relaunch. Although financial resources reduced the ability of organizations to fulfil their mandates, internal factors such as skilled employees and sponsorships, and external factors such as technological improvements in communication and information sharing helped to offset this strain. There were mixed feelings on ParticipACTION's contribution to capacity. While ParticipACTION has brought more attention to inactivity, this was perceived as a complement to work already taking place. While some organizations perceived ParticipACTION's relaunch as competition to funding and access to popular media, others found it as an opportunity to co-brand social marketing campaigns, utilizing ParticipACTION's products and reputation. CONCLUSION: According to participants, organizational capacity to promote physical activity in Canada has increased since 2007 in subtle but important ways because of a strong climate for physical activity promotion, skilled employees, and information sharing technology. Organizational capacity changes were minimally attributed to ParticipACTION.

INTRODUCTION: ParticipACTION est un organisme canadien de communication et de marketing social faisant la promotion de l'activité physique qui a été relancé en 2007. Notre étude visait à évaluer de manière qualitative le pouvoir d'action des organisations canadiennes en matière de promotion de l'activité physique ainsi que l'influence de ParticipACTION sur ce pouvoir cinq ans après sa relance. MÉTHODOLOGIE: Des entrevues téléphoniques semi-structurées ont été réalisées auprès de 44 informateurs clés sélectionnés par échantillonnage dirigé. Les informateurs étaient représentatifs d'organismes nationaux, provinciaux et locaux ayant un mandat en matière de promotion de l'activité physique. Les données tirées des entrevues ont été analysées par thèmes. RÉSULTATS: Depuis la relance de ParticipACTION, le pouvoir d'action en matière de partenariats et de collaborations ainsi que le climat général dans le domaine de la promotion de l'activité physique se sont améliorés. Bien que diverses contraintes financières aient réduit la capacité des organisations à remplir leur mandat, leur impact a été atténué par des facteurs internes comme la présence d'employés compétents et les partenariats ainsi que par des facteurs externes comme les progrès technologiques dans les communications et les échanges d'information. Les avis étaient mitigés en ce qui concerne la contribution de ParticipACTION à l'amélioration de ce pouvoir d'action. Bien que ParticipACTION ait attiré l'attention sur l'inactivité, sa contribution a surtout été perçue comme complémentaire aux activités déjà en place. Certains organismes ont considéré que la relance de ParticipACTION avait accru la compétition pour le financement et l'accès aux médias populaires, tandis que d'autres étaient d'avis qu'il s'agissait d'une opportunité d'établir des partenariats officiels pour des campagnes de marketing social et de tirer parti des réalisations et de la réputation de ParticipACTION. CONCLUSION: Selon les participants, le pouvoir d'action des organisations en matière de promotion de l'activité physique au Canada a augmenté depuis 2007 de façon subtile mais significative, en raison d'un climat favorable à la promotion de l'activité physique, de la présence d'employés compétents et des technologies d'échange d'information. La contribution de ParticipACTION à l'amélioration de ce pouvoir a été jugée faible.

Awareness of ParticipACTION among Canadian adults: a seven-year cross-sectional follow-up. / Notoriété de ParticipACTION auprès des adultes canadiens : étude transversale de suivi après sept ans.

INTRODUCTION: In this cross-sectional follow-up study, we explored Canadian's awareness of ParticipACTION and their levels of physical activity (PA) after seven years of campaigns. METHODS: A population-based survey was conducted with 7282 adults over a period of 14 months from February 2014 to May 2015. The survey consisted of questions on the 2014-2015 Physical Activity Monitor relating to awareness and knowledge of ParticipACTION. Weighted logistic models were constructed to examine whether awareness was associated with PA-related beliefs, intentions, and leisure time physical activity (LTPA). RESULTS: Approximately 20% of Canadians reported unprompted awareness of ParticipACTION and 82% reported prompted awareness. Education, income, and having children were significant correlates of awareness among Canadians. The adjusted odds of people being aware of ParticipACTION (prompted and unprompted) were greater if they were more educated (OR = 1.57, 95% CI: 1.04-2.39; OR = 2.00, 95% CI: 1.24-3.24), reported higher income (OR = 3.92, 95% CI: 2.35-6.53; OR = 2.29, 95% CI: 1.44-3.62), and had children (OR = 1.93, 95% CI: 1.40-2.66; OR = 1.70, 95% CI: 1.26-2.30). Furthermore, awareness of ParticipACTION was positively associated with outcome expectations and self-efficacy, and negatively associated with LTPA status. CONCLUSION: Levels of unprompted awareness of ParticipACTION are higher than previously reported and, in comparison to active Canadians, inactive Canadians are more likely to be aware of the organization. Given that it had primarily targeted parents of inactive children over the past seven years, it appears the organization has been partially effective in achieving its communication goals.

INTRODUCTION: Dans cette étude de suivi transversale, nous avons exploré la notoriété de ParticipACTION et le niveau d'activité physique chez les Canadiens après sept ans de campagnes. MÉTHODOLOGIE: Une enquête à l'échelle de la population a été menée auprès de 7 282 adultes entre février 2014 et mai 2015. Elle a consisté en une série de questions destinées à évaluer la notoriété de ParticipACTION dans le Sondage indicateur de l'activité physique de 2014-2015. Divers modèles de régression logistique pondérée ont été établis pour déterminer si cette notoriété était associée aux croyances à propos de l'activité physique, aux intentions et à l'activité physique pratiquée durant les loisirs. RÉSULTATS: Environ 20 % des Canadiens avaient une connaissance spontanée de ParticipACTION et le taux de notoriété assistée de ParticipACTION était de 82 %. L'éducation, le revenu et le fait d'avoir des enfants étaient significativement corrélés à la notoriété au sein de la population canadienne. Le rapport de cotes (RC) ajusté de la notoriété (assistée et spontanée) de ParticipACTION était plus élevé chez les personnes à haut niveau de scolarité (RC = 1,57, IC à 95 % : 1,04 à 2,39; RC = 2,00, IC à 95 % : 1,24 à 3,24), à revenu élevé (RC = 3,92, IC à 95 % : 2,35 à 6,53; RC = 2,29, IC à 95 % : 1,44 à 3,62) et ayant des enfants (RC = 1,93, IC à 95 % : 1,40 à 2,66; RC = 1,70, IC à 95 % : 1,26 à 2,30). La notoriété de ParticipACTION était également positivement associée aux attentes en matière de résultats et à l'auto-efficacité, et négativement associée à l'activité physique durant les loisirs. CONCLUSION: Le taux de notoriété non assistée de ParticipACTION est plus élevé qu'auparavant et, par ailleurs, les Canadiens inactifs sont plus nombreux que les Canadiens actifs à connaître l'organisme. Étant donné que ParticipACTION a principalement ciblé les parents d'enfants inactifs au cours des sept dernières années, il semble que l'organisme ait partiellement atteint ses objectifs en matière de communication.

Promoting Parent and Child Physical Activity Together: Elicitation of Potential Intervention Targets and Preferences.

Promoting physical activities that involve both parents and their children would be very useful to the improved health and well-being of families, yet coactivity interventions have been particularly unsuccessful in past research. The purpose of this study was to elicit the salient parental beliefs about coactivity framed through theory of planned behavior in order to inform future intervention content. A representative sample of Canadian parents ( N = 483) with children aged 6 to 14 years completed belief elicitation measures of theory of planned behavior, as well as coactivity and program preferences. Analyses included content theming by physical activity belief and preference through tallies of the percentages of parents endorsing each belief. Exploratory analyses of differences in endorsed themes were conducted by parent (mother, father), age of child (6-10 years, 11-14 years), and sex of the child. The results showed that behavioral beliefs about health, interpersonal and educational/learning opportunities and control beliefs about lack of time, various incompatible parent/child factors, parental health, and bad weather were dominant themes. Most of these themes did not vary in endorsement by parent and child characteristics. By contrast, preferences for various activities varied by parent and child characteristics, yet parents overwhelmingly desired the activities to be outdoors, close to home, after work, and originally delivered from community health professionals via Internet or face-to face means. Overall, the findings provide several considerations for specific targets to improve future physical activity intervention approaches among parents and their children.

The Utility of Physical Activity Micro-Grants: The ParticipACTION Teen Challenge Program.

Youth physical activity levels remain low in Canada and worldwide. Lack of environmental resources (e.g., access to equipment and facilities, transportation options, and participation costs) is a key barrier for youth participation. Micro-grants are small budgets of money awarded via grant applications and may help community organizations facilitate youth physical activity participation by alleviating environmental resource barriers. ParticipACTION Teen Challenge was a national micro-grant scheme administered in Canada. Secondary analysis of survey data from Provincial and Territorial coordinators, registered community organizers, and successful grant applicants were used to evaluate the process and outcomes of Teen Challenge. Results showed that the financial subsidy of 500CAD was used mainly toward equipment, instruction, and transportation. Coordinators and community organizers indicated high levels of satisfaction and benefits for communities and teens. A key benefit for coordinators was leveraging the Teen Challenge network for physical activity promotion. Reported benefits for teenaged participants included leadership opportunities (e.g., helping create and implement programs) and increased physical activity participation. Findings highlight the value of micro-grants for supporting sport and physical activity opportunities for Canadian teens, and show that such schemes address barriers related to environmental resources. The sustainability of micro-grant schemes remains to be seen.

Evaluation of a physical activity intervention for new parents: protocol paper for a randomized trial.

BACKGROUND: Identifying critical life transitions in people's physical activity behaviors may illuminate the most opportune intervention apertures for chronic disease prevention. A substantive evidence base now indicates that parenthood is one of these critical transition points for physical activity decline. This study will examine whether a brief theory-based intervention can prevent a decline in physical activity among new parents over 6 months following intervention. This study protocol represents the first dyad-based physical activity initiative in the parenthood literature involving both mothers and fathers; prior research has focused on only mothers or only fathers (albeit limited), and has shown only short-term changes in physical activity. This study will be investigating whether a theory-based physical activity intervention can maintain or improve moderate to vigorous intensity physical activity measured via accelerometry of new parents over a 6 month period following intervention compared to a control group. METHODS: This study is a 6-month longitudinal randomized controlled trial. Parents are measured at baseline (2 months postpartum) with two assessment points at 6 weeks (3.5 months postpartum) and 3 months (5 months postpartum) and a final follow-up assessment at 6 months (8 months postpartum). The content of the theory-based intervention was derived from the results of our prior longitudinal trial of new parents using an adapted theory of planned behavior framework to predict changes in physical activity. RESULTS: A total of 152 couples have been recruited to date. Sixteen couples dropped out after baseline and a total of 88 couples have completed their 6-month measures. DISCUSSION: If the intervention proves successful, couple-based physical activity promotion efforts among parents could be a promising avenue to pursue to help mitigate the declines of physical activity levels during parenthood. These findings could inform public health materials and practitioners. TRIAL REGISTRATION: This trial has been registered with the Clinical Trials Registry maintained by the National Library of Medicine at the National Institutes of Health on April 19, 2014. The registration ID is NCT02290808 .

Physical activity: Health impact, prevalence, correlates and interventions.

OBJECTIVE: To provide a broad overview of the state of physical activity (PA) research in the form of (1) definitions of PA, (2) health benefits, (3) prevalence, (4) correlates and (5) interventions. DESIGN: A high-level overview of published reviews of the literature. RESULTS: Regular PA is an effective primary and secondary preventative strategy against at least 25 chronic medical conditions with risk reduction typically in the 20-30% range. While approximately 75% of adults meet recommended PA guidelines, the prevalence is slightly lower for women compared to men, and considerably lower for youth, older adults and those in higher income countries. Motivation, self-efficacy and self-regulation remain consistent correlates of PA. Interventions show PA changes in the small effect size range for adults and youth but the heterogeneity is considerable across studies. Only a few (aggregate of behavioural regulation strategies, supervision, high frequency of contact) reliable moderators of intervention success were identified across study quality, sample characteristics, theory/behaviour change techniques and delivery modes/settings. CONCLUSION: PA research should continue to examine the mechanisms causing health outcomes, the dose that can lead to clinically relevant changes in health status, the scope and validity of PA surveillance and innovative behaviour change techniques, while improving the reach and duration of PA interventions.
