Interaction of Surface Type, Temperature, and Week of Season on Concussion Risk in the National Football League: A Bayesian Analysis.

BACKGROUND: Artificial turf fields and environmental conditions may influence sports concussion risk, but existing research is limited by uncontrolled confounding factors, limited sample size, and the assumption that risk factors are independent of one another. The purpose of this study was to examine how playing surface, time of season, and game temperature relate to diagnosed concussion risk in the National Football League (NFL). METHODS: This retrospective cohort study examined data from the 2012 to the 2019 NFL regular season. We fit Bayesian negative binomial regression models to relate how playing surface, game temperature, and week of the season independently related to diagnosed concussion risk and any interactions among these factors. RESULTS: We identified 1096 diagnosed concussions in 1830 games. There was a >99% probability that concussion risk was reduced on grass surface (median incidence rate ratio [IRR] = 0.78 [95% credible interval: 0.68, 0.89]), >99% probability that concussion risk was lower at higher temperatures (IRR = 0.85 [0.76,0.95] for each 7.9 °C), and >91% probability that concussion risk increased with each week of the season (IRR = 1.02 [1.00,1.04]). There was an >84% probability for a surface × temperature interaction (IRR = 1.01 [0.96, 1.28]) and >75% probability for a surface × week interaction (IRR = 1.02 [0.99, 1.05]). CONCLUSIONS: Diagnosed concussion risk is increased on artificial turf compared with natural grass, and this is exacerbated in cold weather and, independently, later in the season. The complex interplay between these factors necessitates accounting for multiple factors and their interactions when investigating sports injury risk factors and devising mitigation methods.

The effectiveness of digital sexual health interventions for young adults: a systematic literature review (2010-2020).

There has been a proliferation of digital sexual health interventions targeting adolescents; however, limited evaluative reviews have compared the effectiveness of multiple digital tools for sexual health literacy and behaviour change. This study conducted a systematic literature review, screened 9881 records and analysed 61 studies. Findings suggest that websites and mobile phones dominate digital sexual health interventions, with a majority effectively delivering cognitive (e.g. awareness and attitudes about sexual and reproductive health) and behavioural outcomes (e.g. abstinence and use of contraception). The most popular sexual health promotion mechanisms were interactive websites, text messaging and phone calls, and online education programmes, followed by mobile applications-fewer studies in this review utilized social media, games and multimedia. Previous reviews focused on single outcome measures (e.g. sexually transmitted infection testing) to assess interventions' effectiveness. The current review moves beyond single outcome measures to cover a wider range of behavioural and non-behavioural sexual health issues and contexts covered in the literature. Four main categories were analysed as outcomes: cognitive perceptions, promoting sexual health-related behaviours, promoting sexual health-related products and services, and impact (viral load). Seventy-nine per cent of interventions focused on preventive sexual health behaviours and products (e.g. condoms) and services (e.g. HIV testing). Overall, 75% of studies effectively changed sexual health behaviour and cognitive perceptions. However, the digital-only tools did not vary from the blended formats, in influence outcomes, even after categorizing them into behavioural or non-behavioural outcomes. Compared to previous systematic reviews, more studies from the last decade used rigorous research design in the form of randomized controlled trials, non-randomized control trials, and quasi-experiments and lasted longer.

Sexual health literacy among adolescents is essential to avert unwanted pregnancies or abortions and sexually transmitted diseases. Culturally sensitive and age-appropriate interventions are required to educate youth about safe-sex practices and increase their self-efficacy and accessibility to health products and services. Meta-analytical and systematic literature reviews have identified limitations in traditional interventions that rely heavily on classroom-based activities and lectures to educate adolescents about safe sex. In recent years, digital tools have proved productive; however, limited evaluative reviews have compared the effectiveness of multiple digital technologies (such as smartphones, web-based programs, social media, games and multimedia) used within sexual health interventions. This systematic review assessed 9881 articles and synthesized 61 experimental studies on adolescent sexual behaviour conducted in the last decade to identify tools that positively influence cognitive and safe-sex behaviour among youth. Interactive websites, mobile technology and online education programmes were popular promotional tools, but very few studies utilized multimedia alongside games and social media. Findings from this review could facilitate future research and practice in adolescent sexual health.

Mobile Phone-Based Nutrition Education Targeting Pregnant and Nursing Mothers in Sri Lanka.

INTRODUCTION: A woman's nutrition during pregnancy and nursing affects the mother and the growing child. Similarly, the first two years of a child's life are critical to their growth and development and are facilitated by optimum nutrition. Women's nutrition-related knowledge, attitudes, and practices influence household food and nutrition security. Mobile health (mHealth) is a potentially effective health intervention in pandemic situations when physical gatherings are restricted. OBJECTIVES: To examine the effectiveness of a mobile phone-based nutrition education intervention targeting pregnant and nursing mothers in six Sri Lankan divisional secretariat areas. METHOD: This intervention was evaluated using a before and after within-subjects design. The intervention included 19 messages over four weeks sent via mobile phone, covering nutrition themes such as pregnancy care, infant and young child-feeding, diet, family care for mother and child, and cash management. The intervention was evaluated based on a quantitative survey using a structured interviewer-administered questionnaire and qualitative interviews using a semi-structured questionnaire. The study population was pregnant and nursing mothers. The objective of the qualitative interviews was to identify how respondents used messages and how satisfied they were with the project. The outcome measures were awareness/knowledge, attitudes, social norms, self-efficacy, behaviour intentions, and practices of pregnant and nursing mothers. Trained enumerators collected data using a mobile phone. RESULTS: A total of 996 pregnant and nursing mothers participated in the pre-assessment survey, of which 720 completed the post-assessment. Most were nursing mothers (84.2% pre- and 78.9% post-assessment). Participants provided positive feedback on the intervention. Knowledge/awareness (t = -18.70, p < 0.01) and attitudes (t = -2.00, p < 0.05) increased when exposed to the intervention. Favourable improvements in the practices were also observed. Mothers' practices related to breastfeeding and 24-h dietary diversity showed a statistically significant improvement. However, social norms and behaviour intentions did not significantly improve. The qualitative component also revealed favourable responses. CONCLUSION AND RECOMMENDATIONS: The mobile intervention improved participants' knowledge, awareness, attitude, and practices, but not social norms or behaviour intentions. This approach is recommended to be used on a larger scale in community settings. In addition, mobile technology could drive intervention in pandemic-related situations.

An Integrative Literature Review of Interventions to Protect People with Disabilities from Domestic and Family Violence.

PURPOSE: While domestic and family violence against people with disabilities is an ongoing and crucial public health concern, and awareness of the extent of violence against people with disabilities is growing, research on the field is still limited. Thus, the present review aims to systematically identify and synthesize evidence and effectiveness from intervention strategies to increase the awareness and skills of those with disabilities to reduce and prevent domestic and family violence against them. METHOD: PRISMA guidelines were followed to perform a systematic search of seven scientific databases to identify the peer-reviewed literature. RESULTS: A total of 17 eligible studies were identified (14 evaluations and 3 descriptive studies), with most taking place in developed countries. Children and women are the most frequent victims, and they were therefore the most common target audience of the included studies. Sexual, physical, and verbal abuse were the most reported types of abuse, while financial abuse and neglect were studied less often. Interventions also focused on a diversity of disabilities, including learning, intellectual, mental, and physical impairments. Overall, the intervention strategies reflected a substantial homogeneity: focus on training and education as well as setting up channels and facilities for victims to seek help. Nine studies yielded significant positive outcomes using various strategies and techniques, while five studies had mixed results, and three studies only reported on the intervention strategies but did not evaluate the results. CONCLUSIONS: This review confirms a significant gap in the literature on domestic and family violence against people with disabilities and how to prevent and address the violence through evidence-based interventions. Several recommendations to improve future research and practice are proposed.

COVID-19 vaccine perceptions among South Asian communities in the UK: An application of the theory of planned behavior.

Based on the Theory of Planned Behavior, this paper explores the perceptions of the COVID-19 vaccine among South Asian communities residing in the UK. Thirty-eight semi-structured interviews were conducted using a qualitative approach and analyzed using thematic analysis. Participants represented Indian, Pakistani, Bangladeshi, Sri Lankan, Afghani, and Nepali backgrounds. The participants revealed that family and community influence their perceptions of the COVID-19 vaccine. The results suggest that normalizing vaccine acceptance, addressing unknown side effects, and popularizing vaccine efficacy data will increase vaccine uptake within the South Asian community in the UK.

How scared are Americans of the Zika virus? The role of threat, efficacy, and third-person perception to induce protective behaviors.

This study examines how public perception of threat and efficacy (on self and others) influence their tendency to take preventive action against the Zika virus by surveying 1,152 U.S. adults in Texas and Florida. Findings show that individuals were likely to take protective actions when they: (1) saw a high risk of the disease (high threat) and were confident about their ability to reduce the danger (high efficacy); and (2) perceived others as having a high risk (high threat), but lacked the ability to reduce the danger (low efficacy). Further, the study discusses practical implications for the design of public health campaigns.

Hemoglobin Levels Among Male Agricultural Workers: Analyses From the Demographic and Health Surveys to Investigate a Marker for Chronic Kidney Disease of Uncertain Etiology.

OBJECTIVE: Estimate agricultural work's effect on hemoglobin (Hgb) level in men. A negative effect may indicate presence of chronic kidney disease of uncertain etiology. METHODS: We use Demographic and Health Surveys data from seven African and Asian countries and use matching to control for seven confounders. RESULTS: On average, Hgb levels were 0.09 g/dL lower among agricultural workers compared with matched controls. Significant effects were observed in Ethiopia, India, Lesotho, and Senegal, with effects from 0.07 to 0.30 g/dL lower Hgb level among agricultural workers. The findings were robust to multiple control groups and a modest amount of unmeasured confounding. CONCLUSIONS: Men engaged in agricultural work in four of the seven countries studied have modestly lower Hgb levels. Our data support integrating kidney function assessments within Demographic and Health Surveys and other population-based surveys.

Understanding Factors to COVID-19 Vaccine Adoption in Gujarat, India.

The COVID-19 pandemic has posed threats to human life across the globe, including India. Vaccinating is an effective means of addressing the pandemic threat. The government of India has implemented a massive vaccination drive to save its citizens from the deadly virus. However, the effort has faced multiple challenges, including vaccine hesitancy. This research understands respondents' perspectives on factors contributing to the lower vaccination uptake in Gujarat, India. Forty-four semi-structured interviews were conducted through convenience sampling representing different demographic backgrounds. Factors influencing vaccine adoption included religious leadership, political leadership and the government, and fear of side effects, especially among children and those with co-morbidities, resulting primarily from fake news and misinformation circulated through social media. Compared with nine countries from across the world, the study found similarities to vaccine hesitancy from misinformation and the fear of side effects among children. In contrast, the role of government and the influence of religious and political leaders was considered positive. The study recommends strategies to overcome people's apprehensions about the adoption of vaccination. These include offering incentives, providing positive peer-to-peer communication, recruiting influencers such as religious and community leaders and early adopters such as the elderly population to endorse vaccination, targeting youth through social media, and reaching rural sections by involving NGOs and social service groups.

Motivators of Indiscriminate and Unsafe Supplement Use among Young Australians.

BACKGROUND: There is growing concern about the self-administration of supplements, which can often be indiscriminate, counterproductive to health, and serve as a gateway to more harmful drugs and substances. Research suggests that high uptake of performance- and image-enhancing drugs (PIEDs) is correlated with body image to accentuate masculinity. This study provides insights into limiting unhealthy supplement usage. This research identifies reasons for casual unhealthy supplement use among young adult Australians through the Theory of Planned Behavior (TPB) lens, providing practitioners with insights into developing interventions to deter their use. METHOD: Semi-structured in-depth interviews were conducted with ten participants aged between 18 and 40, using a convenience sample. Leximancer analysis was used to assess word co-occurrence and map to TPB constructs. RESULTS: Leximancer identified positive attitudes, social norms, and perceived behavioral control towards supplement usage. Key themes that influenced supplement use were weight loss, body image, nutrition, training, education, challenges, need, and time. Furthermore, using TPB constructs, affective and instrumental attitudes and prevailing norms were observed when investigating what would cause an individual to use supplements in an unhealthy manner. CONCLUSION: Through understanding the motivations of indiscriminate supplement use across the Australian population, the study has uncovered several social factors that may reduce or limit the practice of unsafe supplement usage.

Retrospective survey of youth sports participation: Development and assessment of reliability using school records.

Many youths participate in sports, and it is of interest to understand the impact of youth sports participation on later-life outcomes. However, prospective studies take a long time to complete and retrospective studies may be more practical and time-efficient to address some questions. We pilot a retrospective survey of youth sports participation and examine agreement between respondent's self-reported participation with high school records in a sample of 84 adults who graduated from high school between 1948 and 2018. The percent agreement between our survey and the school resources for individual sports ranged between 91.5% and 100%. These findings provide preliminary evidence for the reliability of retrospective self-report of youth sports participation. This survey may serve as an efficient approach for evaluating relationships between involvement in youth sports and health outcomes later in adulthood.

Community perspectives and engagement in sustainable solid waste management (SWM) in Fiji: A socioecological thematic analysis.

Improper waste disposal and low rates of household waste diversion through material and organic waste recycling are a global concern. Understanding community perspectives on solid waste management services, outreach activities, and regulatory measures, and the barriers to sustainable practices, is crucial for designing effective waste management programmes. Longitudinal content analysis of archival data, such as newspapers, is a cost-effective, yet underutilised, research method to identify the viewpoints of diverse civic groups and examine the developments and challenges associated with the waste management sector. This paper investigates divergent stakeholders' perspectives and priorities using the Socio-Ecological Model (SEM) to examine the micro-system (intrapersonal and interpersonal), meso- and exo-system (community and institutional), and macro-system (policy level) factors that influence sustainable SWM practices. Using specific keywords, the authors searched online archives of a national newspaper in Fiji with a weekday circulation of over 20,000. Data from 482 newspaper articles, dated 2009-2020, were reviewed and dual-coded by two researchers using QDA Miner Lite. Findings indicate that poor waste management behaviour is linked to all factors within the Socio-Ecological system. While micro-level factors such as negligence, personal responsibility, lack of civic pride, and lack of awareness are causes of anti-environmental behaviour, structural factors such as inadequate waste collection services and recycling infrastructure contribute to low recycling rates. Civic education has been highlighted as a solution to encouraging pro-environmental behaviour (PEB), but there is a need to identify the type of educational tools and the frequency and impact of education workshops. This paper further discusses about the implications of community-based strategies and regulatory measures.

Participation in Collision Sports and Cognitive Aging Among Swedish Twins.

We examined the association between early-life participation in collision sports and later-life cognitive health over a 28-year period in a population-based sample drawn from the longitudinal Swedish Adoption/Twin Study of Aging (1987-2014). Cognitive measures included the Mini-Mental State Examination and performance across multiple cognitive domains (e.g., global cognition, verbal ability, spatial ability, memory, processing speed). Among a sample of 660 adults (mean age at baseline, 62.8 years (range: 50-88); 58.2% female), who contributed 10,944 person-years of follow-up, there were 450 cases of cognitive impairment (crude rate = 41.1/1,000 person-years). Early-life participation in collision sports was not significantly associated with cognitive impairment at baseline or with its onset over a 28-year period in a time-to-event analysis, which accounted for the semi-competing risk of death. Furthermore, growth curve models revealed no association between early-life participation in collision sports and the level of or change in trajectories of cognition across multiple domains overall or in sex-stratified models. We discuss the long-term implications of adolescent participation in collision sports on cognitive health.

Influencing household-level waste-sorting and composting behaviour: What works? A systematic review (1995-2020) of waste management interventions.

Decentralized waste sorting and composting can divert almost two-thirds of household waste from landfill. However, national rates of composting and recycling remain low in many parts of the globe. This review critically evaluates the design and efficacy of behaviour-change interventions to influence households to sort and compost organic waste. The systematic literature search yielded 3595 titles and abstracts which were reviewed and resulted in 14 unique interventions. The social marketing benchmark criteria are utilized to critically examine the design of these interventions. Synthesized results indicate a need for customized interventions that are co-designed with users and tailored to address their specific needs and challenges. Interventions with four or more social marketing elements produced positive behavioural outcomes, albeit with varying impact. This review highlights gaps in the design of waste management interventions and provides suggestions for future practices.

A systematic review of the effectiveness of mass media campaigns for the management of low back pain.

PURPOSE: To synthesize evidence on the effectiveness of mass media campaigns for the management of LBP on beliefs of the general public and health care providers, LBP-related disability, health utilization, and LBP clinical outcomes. MATERIALS AND METHODS: Five electronic databases were searched from inception to December 17, 2019. Any studies evaluating the effectiveness of mass media campaigns for LBP were eligible. Primary outcome was general public LBP beliefs, while secondary outcomes included health care provider beliefs as well as LBP-related disability, health utilization, and clinical outcomes. RESULTS: The search resulted in 4,164 unique records, of which 18 studies were included. These 18 studies predominantly used quasi-experimental methods to evaluate seven LBP mass media campaigns conducted in seven countries. All studies evaluating LBP beliefs in the general public detected positive effects. Health care provider beliefs also consistently improved. Results for behavioural outcomes (disability behaviour and health utilization) were mixed and appeared dependent on campaign characteristics and local context. CONCLUSIONS: Mass media campaigns for LBP appear effective for improving beliefs of the general public and health care providers. REGISTRATION: Prospero CRD42018116797IMPLICATIONS FOR REHABILITATIONMass media campaigns about low back pain (LBP) appear effective for improving beliefs of the general public and health care providers, aligning beliefs with current evidence and self-management principles.Rehabilitation professionals should be aware of and seek to support public education initiatives in their communities related to LBP and other disabling health conditions.Rehabilitation professionals can highlight and reinforce campaign messages when providing education and reassurance to individual patients.Several campaign resources (i.e., posters, pamphlets, electronic resources, etc.) are available for rehabilitation professionals to use in their efforts to reduce disability related to LBP.

Key Guidelines in Developing a Pre-Emptive COVID-19 Vaccination Uptake Promotion Strategy.

This paper makes the case for immediate planning for a COVID-19 vaccination uptake strategy in advance of vaccine availability for two reasons: first, the need to build a consensus about the order in which groups of the population will get access to the vaccine; second, to reduce any fear and concerns that exist in relation to vaccination and to create demand for vaccines. A key part of this strategy is to counter the anti-vaccination movement that is already promoting hesitancy and resistance. Since the beginning of the COVID-19 pandemic there has been a tsunami of misinformation and conspiracy theories that have the potential to reduce vaccine uptake. To make matters worse, sections of populations in many countries display low trust in governments and official information about the pandemic and how the officials are tackling it. This paper aims to set out in short form critical guidelines that governments and regional bodies should take to enhance the impact of a COVID-19 vaccination strategy. We base our recommendations on a review of existing best practice guidance. This paper aims to assist those responsible for promoting COVID-19 vaccine uptake to digest the mass of guidance that exists and formulate an effective locally relevant strategy. A summary of key guidelines is presented based on best practice guidance.

The association between adolescent football participation and early adulthood depression.

Concerned about potentially increased risk of neurodegenerative disease, several health professionals and policy makers have proposed limiting or banning youth participation in American-style tackle football. Given the large affected population (over 1 million boys play high school football annually), careful estimation of the long-term health effects of playing football is necessary for developing effective public health policy. Unfortunately, existing attempts to estimate these effects tend not to generalize to current participants because they either studied a much older cohort or, more seriously, failed to account for potential confounding. We leverage data from a nationally representative cohort of American men who were in grades 7-12 in the 1994-95 school year to estimate the effect of playing football in adolescent on depression in early adulthood. We control for several potential confounders related to subjects' health, behavior, educational experience, family background, and family health history through matching and regression adjustment. We found no evidence of even a small harmful effect of football participation on scores on a version of the Center for Epidemiological Studies Depression scale (CES-D) nor did we find evidence of adverse associations with several secondary outcomes including anxiety disorder diagnosis or alcohol dependence in early adulthood. For men who were in grades 7-12 in the 1994-95 school year, participating or intending to participate in school football does not appear to be a major risk factor for early adulthood depression.

Observational Study of the Associations of Participation in High School Football With Self-Rated Health, Obesity, and Pain in Adulthood.

American football is the most popular high school sport in the United States, yet its association with health in adulthood has not been widely studied. We investigated the association between high school football and self-rated health, obesity, and pain in adulthood in a retrospective cohort study of data from the Wisconsin Longitudinal Study (1957-2004). We matched 925 males who played varsity football in high school with 1,521 males who did not play football. After matching, playing football was not associated with poor or fair self-rated health (odds ratio (OR) = 0.88, 95% confidence interval (CI): 0.63, 1.24; P = 0.48) or pain that limited activities (OR = 0.86, 95% CI: 0.59, 1.25; P = 0.42) at age 65 years. Football was associated with obesity (body mass index (weight (kg)height (m)2) ≥30) in adulthood (OR = 1.32, 95% CI: 1.06, 1.64; P = 0.01). The findings suggest that playing football in high school was not significantly associated with poor or fair self-related health at age 65 years, but it was associated with the risk of being obese as an adult in comparison with not playing football in high school. Our findings provide needed information about the risk of playing football with regard to a broader set of health outcomes.

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.
