RESUMO
BACKGROUND: Whole-of-school programs have demonstrated success in improving student physical activity levels, but few have progressed beyond efficacy testing to implementation at-scale. The purpose of our study was to evaluate the scale-up of the 'Internet-based Professional Learning to help teachers promote Activity in Youth' (iPLAY) intervention in primary schools using the RE-AIM framework. METHODS: We conducted a type 3 hybrid implementation-effectiveness study and collected data between April 2016 and June 2021, in New South Wales (NSW), Australia. RE-AIM was operationalised as: (i) Reach: Number and representativeness of students exposed to iPLAY; (ii) Effectiveness: Impact of iPLAY in a sub-sample of students (n = 5,959); (iii) Adoption: Number and representativeness of schools that received iPLAY; (iv) Implementation: Extent to which the three curricular and three non-curricular components of iPLAY were delivered as intended; (v) Maintenance: Extent to which iPLAY was sustained in schools. We conducted 43 semi-structured interviews with teachers (n = 14), leaders (n = 19), and principals (n = 10) from 18 schools (11 from urban and 7 from rural locations) to determine program maintenance. RESULTS: Reach: iPLAY reached ~ 31,000 students from a variety of socio-economic strata (35% of students were in the bottom quartile, almost half in the middle two quartiles, and 20% in the top quartile). EFFECTIVENESS: We observed small positive intervention effects for enjoyment of PE/sport (0.12 units, 95% CI: 0.05 to 0.20, d = 0.17), perceptions of need support from teachers (0.26 units, 95% CI: 0.16 to 0.53, d = 0.40), physical activity participation (0.28 units, 95% CI: 0.10 to 0.47, d = 0.14), and subjective well-being (0.82 units, 95% CI: 0.32 to 1.32, d = 0.12) at 24-months. Adoption: 115 schools received iPLAY. IMPLEMENTATION: Most schools implemented the curricular (59%) and non-curricular (55%) strategies as intended. Maintenance: Based on our qualitative data, changes in teacher practices and school culture resulting from iPLAY were sustained. CONCLUSIONS: iPLAY had extensive reach and adoption in NSW primary schools. Most of the schools implemented iPLAY as intended and effectiveness data suggest the positive effects observed in our cluster RCT were sustained when the intervention was delivered at-scale.

BACKGROUND: Participating in regular physical activity is a recommended cancer recovery strategy for breast cancer survivors. However, tailored support services are not widely available and most survivors are insufficiently active to obtain health benefits. Delivering tailored programs via the Internet offers one promising approach. However, recent evaluations of such programs suggest that major improvements are needed to ensure programs meet the needs of users and are delivered in an engaging way. Understanding participants' experiences with current programs can help to inform the next generation of systems. PURPOSE: The purposes of this study are to explore breast cancer survivor's perspectives of and experiences using a novel computer-tailored intervention and to describe recommendations for future iterations. METHODS: Qualitative data from a sub-sample of iMove More for Life study participants were analysed thematically to identify key themes. Participants long-term goals for participating in the program were explored by analysing open-ended data extracted from action plans completed during the intervention (n = 370). Participants negative and positive perceptions of the website and recommendations for improvement were explored using data extracted from open-ended survey items collected at the immediate intervention follow-up (n = 156). RESULTS: The majority of participants reported multi-faceted goals, consisting of two or more outcomes they hoped to achieve within a year. While clear themes were identified (e.g. 'being satisfied with body weight'), there was considerable variability in the scope of the goal (e.g. desired weight loss ranged from 2 to 30 kg). Participants' perceptions of the website were mixed, but clear indications were provided of how intervention content and structure could be improved. CONCLUSIONS: This study provides insight into how to better accommodate breast cancer survivors in the future and ultimately design more engaging computer-tailored interventions.

BACKGROUND: Physical inactivity levels are unacceptably high and effective interventions that can increase physical activity in large populations at low cost are urgently needed. Web-based interventions that use computer-tailoring have shown to be effective, though people tend to 'skim' and 'scan' text on the Internet rather than thoroughly read it. The use of online videos is, however, popular and engaging. Therefore, the aim of this 3-group randomised controlled trial is to examine whether a web-based physical activity intervention that provides personally-tailored videos is more effective when compared with traditional personally-tailored text-based intervention and a control group. METHODS/DESIGN: In total 510 Australians will be recruited through social media advertisements, e-mail and third party databases. Participants will be randomised to one of three groups: text-tailored, video-tailored, or control. All groups will gain access to the same web-based platform and a library containing brief physical activity articles. The text-tailored group will additionally have access to 8 sessions of personalised physical activity advice that is instantaneously generated based on responses to brief online surveys. The theory-based advice will be provided over a period of 3 months and address constructs such as self-efficacy, motivation, goal setting, intentions, social support, attitudes, barriers, outcome expectancies, relapse prevention and feedback on performance. Text-tailored participants will also be able to complete 7 action plans to help them plan what, when, where, who with, and how they will become more active. Participants in the video-tailored group will gain access to the same intervention content as those in the text-tailored group, however all sessions will be provided as personalised videos rather than text on a webpage. The control group will only gain access to the library with generic physical activity articles. The primary outcome is objectively measured physical activity. Secondary outcomes include website engagement and retention, quality of life, depression, anxiety, stress, sitting time, sleep and psychosocial correlates of physical activity. Outcomes will be measured at baseline, 3, and 9 months. DISCUSSION: This study presents an ideal opportunity to study the effectiveness of an isolated feature within a web-based physical activity intervention and the knowledge generated from this study will help to increase intervention effectiveness.

BACKGROUND: High-intensity interval training (HIIT) may be a feasible and efficacious strategy for improving health-related fitness in young people. The objective of this systematic review and meta-analysis was to evaluate the utility of HIIT to improve health-related fitness in adolescents and to identify potential moderators of training effects. METHODS: Studies were considered eligible if they: (1) examined adolescents (13-18â years); (2) examined health-related fitness outcomes; (3) involved an intervention of ≥4â weeks in duration; (4) included a control or moderate intensity comparison group; and (5) prescribed high-intensity activity for the HIIT condition. Meta-analyses were conducted to determine the effect of HIIT on health-related fitness components using Comprehensive Meta-analysis software and potential moderators were explored (ie, study duration, risk of bias and type of comparison group). RESULTS: The effects of HIIT on cardiorespiratory fitness and body composition were large, and medium, respectively. Study duration was a moderator for the effect of HIIT on body fat percentage. Intervention effects for waist circumference and muscular fitness were not statistically significant. CONCLUSIONS: HIIT is a feasible and time-efficient approach for improving cardiorespiratory fitness and body composition in adolescent populations.

OBJECTIVE: To examine the longitudinal associations between different physical activity (PA) intensities and cardiometabolic risk factors among a sample of Canadian youth. METHODS: The findings are based on a 2-year prospective cohort study in a convenience sample of 315 youth aged 9-15 years at baseline from rural and urban schools in Alberta, Canada. Different intensities (light, moderate and vigorous) of PA were objectively assessed with Actical accelerometers. The main outcome measures were body mass index (BMI) z-score, waist circumference, cardiorespiratory fitness and systolic blood pressure at 2-year-follow-up and conditional BMI z-score velocity. A series of linear regression models were conducted to investigate the associations after adjusting for potential confounders. RESULTS: At follow-up, cardiorespiratory fitness increased (quartile 1 vs quartile 4=43.3 vs 50.2; P(trend)<0.01) and waist circumference decreased (quartile 1 vs quartile 4=79.0 vs 72.6; P(trend)=0.04; boys only) in a dose-response manner across quartiles of baseline vigorous-intensity PA. A similar trend was observed for systolic blood pressure (quartile 1 vs quartile 4=121.8 vs 115.3; P(trend)=0.07; boys only). Compared with quartile 1 of vigorous-intensity PA, BMI z-score at follow-up and conditional BMI z-score velocity were significantly lower in the quartile 2 and 3 (P<0.05). Waist circumference at follow-up also decreased (quartile 1 vs quartile 4=75.3 vs 73.8; P(trend)=0.04) across quartiles of baseline moderate-intensity PA. CONCLUSIONS: Time spent in vigorous-intensity PA was associated with several positive health outcomes 2 years later. These findings suggest that high-intensity activities in youth help to reduce the risk for several chronic diseases.

BACKGROUND: Physical activity (PA) is associated with reduced morbidity and mortality in individuals with type 2 diabetes mellitus (T2DM); however, most T2DM adults are insufficiently active. PURPOSE: To explore the effectiveness of two innovative/theoretically based behavioral-change strategies to increase PA and reduce hemoglobin A1c (A1c) in T2DM adults. METHODS: Participants (n = 287) were randomly assigned to a control group or an intervention group (i.e., print-based materials/pedometer group or print-based materials/pedometer plus telephone-counseling group). Changes in PA and A1c and other clinical measures were examined by Linear Mixed Model analyses over 18 months, along with moderating effects for gender and age. RESULTS: PA and A1c levels did not significantly change in intervention groups. Step counts significantly increased in the print-based materials and pedometer plus telephone counseling group, for women. CONCLUSIONS: No significant effects were found for PA or A1c levels for T2DM adults. The multi-component strategy including telephone counseling may have potential for women. The trial was registered on ClinicalTrials.gov identifier: NCT00221234.

OBJECTIVE: The aim of this study was to design and evaluate a brief scale to assess adolescents' motivation to limit their screen-time using a self-determination theory (SDT) framework. METHODS: The development and evaluation of the Motivation to Limit Screen-time Questionnaire (MLSQ) involved three phases. In Phase 1, experts in SDT were asked to review the content validity of the MLSQ items. In Phase 2, adolescent boys (N=342, mean age=12.7 ±.5 years) completed the MLSQ and the factorial validity of the model was explored. In Phase 3, adolescent boys (N=48, mean age=14.3 ± 1.3 years) completed the MLSQ on two occasions separated by 1-week. Phases 2 and 3 were conducted in New South Wales, Australia in 2012. RESULTS: Twenty four SDT experts reviewed the original scale items. Validity coefficients associated with six of the original eight items exceeded the threshold value (V>.68, p<.01). In Phase 2, the revised three-factor (9-items) model provided a good fit to the data (SRMR=.07, CFI=.96). The intraclass correlation (ICC) values were .67 for amotivation and .70 and .82 for controlled and autonomous motivation, respectively. CONCLUSION: This study has provided preliminary evidence for the validity and reliability of the MLSQ in adolescent boys.

PURPOSE: To investigate whether a home-based resistance training (RT) program that supplied high-quality equipment and qualified exercise specialists could provide benefits to obese patients with type 2 diabetes. METHODS: A total of 48 obese individuals with type 2 diabetes were randomly assigned to either an RT (n=27) or a control group (n=21). Those in the RT group received a multigym and dumbbells and performed RT 3 days per week for 16 weeks at home. A qualified exercise specialist supervised training, with supervision being gradually decreased throughout the study. Primary outcome measures included strength and hemoglobin-A1C, whereas secondary outcome measures included other cardiovascular risk markers, key social-cognitive constructs and health-related quality of life. RESULTS: Intention-to-treat analyses indicated a significant increase in upper and lower body strength for the RT group compared with controls (20-37% mean increases in the RT group). No significant reduction in A1C levels was observed. The RT group had unchanged high-density lipoprotein cholesterol levels in comparison to declines in the control group. Significant reductions in fasting insulin, and increases in RT-related self-efficacy and intentions, were also observed in the RT group. CONCLUSIONS: Supervised home-based RT with high-quality equipment was effective for improving strength, along with other secondary outcomes in obese patients with type 2 diabetes.

OBJECTIVE: To assess the feasibility of employing an ecologically guided childhood obesity relevant surveillance system. METHODS: Cross-sectional qualitative and quantitative data were collected from 31 organizational representatives across 28 unique organizations and/or departments from three purposively sampled communities in the Capital Health Region in Alberta, Canada. RESULTS: All the organizational representatives surveyed reported awareness of childhood obesity and 36% reported participation in child obesity initiatives. Data to support a surveillance system are available but not in a suitable format, and privacy legislation present significant barriers. Interest in developing and sustaining an ecologically based surveillance system was low (18%). CONCLUSION: Due to the heterogeneity of available data and limited vision for the development and implementation of a surveillance system, the application of an ecologically based surveillance system relevant to childhood obesity may be constrained. Broad-based awareness of childhood obesity by a wide range of organizations could assist in establishing an effective coalition to address this issue over the long term by supporting the establishment of a surveillance system.

PURPOSE: The purpose of the study is to investigate the impact of differing delivery schedules of computer-tailored physical activity modules on engagement and physical activity behaviour change in a web-based intervention targeting breast cancer survivors. METHODS: Insufficiently active breast cancer survivors (n = 492) were randomly assigned to receive one of the following intervention schedules over 12 weeks: a three-module intervention delivered monthly, a three-module intervention delivered weekly or a single module intervention. Engagement with the website (number of logins, time on site, modules viewed, action plans completed) was measured using tracking software. Other outcomes (website acceptability, physical activity behaviour) were assessed using online surveys. Physical activity outcomes were analysed using regression models for both study completers and when applying intention-to-treat (using multiple imputation). RESULTS: Completers allocated to the monthly module group rated the intervention higher (b = 2.2 95 % CI = 0.02-4.53) on acceptability and had higher levels of resistance-training (IRR = 1.88, 95 % CI = 1.16-3.04) than those in the single module group. When accounting for missing data, these differences were no longer significant. The completion of at least two action plans was higher among those allocated to the monthly module group compared to those in the weekly module group (53 vs 40 %, p = 0.02); though the completion of at least two modules was higher in the weekly module group compared to the monthly module group (60 vs 46 %; p = 0.01). There were no other significant between group differences observed. CONCLUSION: This study provides preliminary evidence that web-based computer-tailored interventions can be used to increase physical activity among breast cancer survivors. Further, there were some outcome differences based on how the tailored modules were delivered, with the most favourable outcomes observed in the monthly delivery group. IMPLICATIONS FOR CANCER SURVIVORS: This study will be useful for informing the design of future web-based interventions targeting breast cancer survivors.

INTRODUCTION: Overweight and obesity are influenced by a complex interplay of individual and environmental factors that affect physical activity and healthy eating. Nevertheless, little has been reported on people's perceptions of those factors. Addressing this critical gap and community partner needs, this study explored how people perceived the influence of micro- and macroenvironmental factors on physical activity and healthy eating. METHODS: Community partners wanted the study results in a format that would be readily and easily used by local decision makers. We used photovoice to engage 35 community members across four municipalities in Alberta, Canada, and to share their narratives about their physical activity and healthy eating. A combination of inductive and deductive analysis categorized data by environmental level (micro vs. macro) and type (physical, political, economic, and sociocultural), guided by the Analysis Grid for Environments Linked to Obesity Framework. RESULTS: Participants conceptualized health-influencing factors more broadly than physical activity and healthy eating to include "community social health." Participants spoke most often about the influence of the microenvironment (n = 792 ANGELO Framework coding tallies) on their physical activity, healthy eating and community social health in comparison to the macroenvironment (n = 93). Photovoice results provided a visual narrative to community partners and decision makers about how people's ability to make healthy choices can be limited by macroenvironmental forces beyond their control. CONCLUSION: Focussing future research on macro- and microenvironmental influences and localized community social health can inform practice by providing strategies on how to implement healthy changes within communities, while ensuring that research and interventions echo diverse people's perceptions.
INTRODUCTION: Le surpoids et l'obésité dépendent de l'interaction complexe entre facteurs liés à l'indivu et facteurs liés à l'environnement ayant une influence sur l'activité physique et une alimentation saine. Il existe pourtant peu d'information sur les perceptions des individus à l'égard de ces facteurs. Afin de combler cette lacune importante et de répondre aux besoins de nos partenaires des collectivités, nous examinons comment les individus perçoivent l'influence des facteurs micro- et macroenvironnementaux sur leur activité physique et leur alimentation. MÉTHODOLOGIE: Nos partenaires des collectivités souhaitaient que les résultats de l'étude soient diffusés dans un format facile à utiliser par les décideurs locaux. Avec la méthode photovoix, nous avons motivé 35 membres issus de quatre collectivités de l'Alberta (Canada) à fournir leurs témoignages à propos de leur activité physique et d'une alimentation saine. Nous avons employé une combinaison d'analyses inductives et déductives pour classer les données par niveau (micro et macro) d'environnement et par type (environnement physique, politique, économique et socioculturel), à l'aide de la Grille d'analyse des environnements liés à l'obésité (ANGELO). RÉSULTATS: Pour les participants, les facteurs liés à la santé étaient plus larges que l'activité physique et une alimentation saine, incluant la « santé sociocommunautaire ¼. Les participants ont parlé plus souvent de l'influence du microenvironnement (score de 792 après codage au moyen du cadre ANGELO) sur l'activité physique, une alimentation saine ou la santé sociocommunautaire que sur l'influence du macroenvironnement (score de 93). Les résultats obtenus avec la méthode photovoix ont fourni aux partenaires des collectivités et aux décideurs un témoignage visuel de la manière dont la capacité des individus à faire des choix sains peut être restreinte par des forces macroenvironnementales qui échappent à leur contrôle. CONCLUSION: Axer les recherches ultérieures sur les influences et macroenvironnementales et microenvironnementales ainsi que sur la santé sociocommunautaire locale sera utile, car cela alimentera les stratégies de changement en vue d'améliorer la santé des collectivités tout en garantissant que la recherche et les interventions font écho aux perceptions diverses de la population.

Sedentary behaviour has emerged as a unique determinant of health in adults. Studies in children and adolescents have been less consistent. We reviewed the evidence to determine if the total volume and patterns (i.e. breaks and bouts) of objectively measured sedentary behaviour were associated with adverse health outcomes in young people, independent of moderate-intensity to vigorous-intensity physical activity. Four electronic databases (EMBASE MEDLINE, Ovid EMBASE, PubMed and Scopus) were searched (up to 12 November 2015) to retrieve studies among 2- to 18-year-olds, which used cross-sectional, longitudinal or experimental designs, and examined associations with health outcomes (adiposity, cardio-metabolic, fitness, respiratory, bone/musculoskeletal, psychosocial, cognition/academic achievement, gross motor development and other outcomes). Based on 88 eligible observational studies, level of evidence grading and quantitative meta-analyses indicated that there is limited available evidence that the total volume or patterns of sedentary behaviour are associated with health in children and adolescents when accounting for moderate-intensity to vigorous-intensity physical activity or focusing on studies with low risk of bias. Quality evidence from studies with robust designs and methods, objective measures of sitting, examining associations for various health outcomes, is needed to better understand if the overall volume or patterns of sedentary behaviour are independent determinants of health in children and adolescents.

Current physical activity and fitness levels among adolescents are low, increasing the risk of chronic disease. Although the efficacy of high intensity interval training (HIIT) for improving metabolic health is now well established, it is not known if this type of activity can be effective to improve adolescent health. The primary aim of this study is to assess the effectiveness and feasibility of embedding HIIT into the school day. A 3-arm pilot randomized controlled trial was conducted in one secondary school in Newcastle, Australia. Participants (n = 65; mean age = 15.8(0.6) years) were randomized into one of three conditions: aerobic exercise program (AEP) (n = 21), resistance and aerobic exercise program (RAP) (n = 22) and control (n = 22). The 8-week intervention consisted of three HIIT sessions per week (8-10 min/session), delivered during physical education (PE) lessons or at lunchtime. Assessments were conducted at baseline and post-intervention to detect changes in cardiorespiratory fitness (multi-stage shuttle-run), muscular fitness (push-up, standing long jump tests), body composition (Body Mass Index (BMI), BMI-z scores, waist circumference) and physical activity motivation (questionnaire), by researchers blinded to treatment allocation. Intervention effects for outcomes were examined using linear mixed models, and Cohen's d effect sizes were reported. Participants in the AEP and RAP groups had moderate intervention effects for waist circumference (p = 0.024), BMI-z (p = 0.037) and BMI (not significant) in comparison to the control group. A small intervention effect was also evident for cardiorespiratory fitness in the RAP group.
RESUMO
This study addresses the issue of the long term retention of Expired Air Resuscitation (EAR) knowledge and skills. The subjects were one hundred and two secondary school students, half of whom had received training in EAR procedures 5 years prior to this study. Data were collected from these subjects in relation to their knowledge of the EAR procedures and their ability to implement these procedures. In general the students who had undergone the EAR training 5 years ago performed better in the practical tasks than did their untrained counterparts. While there was virtually no difference in the theoretical knowledge section overall, the trained group did perform better on a number of questions.

PURPOSE: The purpose of this study was to investigate the factors associated with exercise behavior among adults with diabetes. METHODS: Exercise behavior (stage of exercise readiness and energy expenditure) and potential determinants were measured on a subsample (n = 46) of adults with type 1 or type 2 diabetes from a randomized population-based telephone survey. Participants were assessed at baseline and at a 6-month follow-up. RESULTS: Sociodemographic and biomedical characteristics did not significantly differ between the stages of exercise behavior. Scores on the psychosocial constructs of self-efficacy, behavioral processes, self-concept, and social support were significantly higher for those in the action stage than those in the preaction stage of exercise readiness. Self-efficacy and behavioral process of change were significantly associated with energy expenditure; self-efficacy was the strongest predictor in the longitudinal analysis. CONCLUSIONS: These findings may generate direction for theory development and guide health and medical practitioners when intervening on the specific constructs. Population- and community-based surveys have utility for assessing diabetes health-related behavior (e.g., exercise behavior).

OBJECTIVES: To predict exercise stage transitions over two consecutive 6-month periods using the theory of planned behaviour (TPB). It was hypothesized that different social cognitive constructs would predict different stage transitions. DESIGN: Prospective and longitudinal in order to predict multiple stage transitions over time. Assessments were made at baseline, 6 months and 1 year. METHOD: Participants were a randomly selected population-based sample of 683 adults who completed two telephone interviews (baseline and 6 months) that assessed exercise stage, intention, perceived behavioural control, attitude, subjective norm, and social support, and a mailed survey (1 year) that assessed exercise stage. RESULTS: Progression from pre-contemplation was predicted by intention, attitude and subjective norm; progression/regression from contemplation was predicted by intention, perceived behavioural control, attitude, and social support; progression/regression from preparation was predicted by intention and attitude; and regression from action/maintenance was predicted by intention, attitude and social support. CONCLUSIONS: Different social cognitive constructs predicted different stage transitions, which indicates that exercise behaviour change may be represented by a series of stage transitions. Moreover, the TPB may be a useful model for highlighting the key social cognitive constructs that are important for exercise stage transitions.
RESUMO
This study examined the prevalence and profiles of behavioural and biomedical risk factors of heart disease in a randomized community sample of 843 Canadian women. Sociodemographic characteristics were also examined to determine their association with women who have multiple primary risk factors versus risk factor-free women. A greater proportion of high-risk women (n = 81) reported to have less education, lower income and employment levels and were more likely to live without a partner than women with no primary risk factors (n = 135). These findings contribute to the understanding of the growing complexity of addressing heart health beyond lifestyle behaviours as articulated by the Victoria (1992), Catelonia (1995), Singapore (1998) and Women's International (2000) Declarations on Heart Health. Public health planning should continue to address physical activity, smoking and dietary behaviours across age groups with a concentrated effort to target high-risk, socio-economically disadvantaged women. Risk assessment for heart disease must also include sociodemographic characteristics for tailoring heart health programs in the community.

One of the important implications of a population health perspective in public health is an increase in the need for transdisciplinary ways of working. The Community Health Research Unit (CHRU) is presented as an example of an environment where psychology and psychologists work with other disciplines to conduct applied research in population health. Research activities were examined to identify how the disciplines collaborate and to provide evidence of successful interdisciplinary and transdisciplinary approaches which incorporate health psychology. The strengths and challenges of multi-, inter-, and transdisciplinary approaches were examined through a poll of CHRU members. Further, members' views about the contributions of psychology to their work were gathered. Issues of working with different disciplines in a transdisciplinary approach are highlighted and future directions are suggested.
RESUMO
This study examines perspective transformation (or professional resocialization) in RN-to-BSN students obtaining their degree by distance education. A socialization scale was used to compare newly admitted and graduating RN-to-BSN students who had taken their courses onsite, by distance education, or a mixture of the two methods. The scores of entering and graduating RN-to-BSN students also were compared to those of graduates from the generic program to identify if program and experience are factors in scores achieved. Results indicate that all BSN graduates had significantly higher scores than the diploma-prepared nurses entering the RN-to-BSN program. RN-to-BSN graduates who had used distance education had the highest scores, followed by the onsite RN-to-BSN students. Students who had taken a mixture of distance and onsite courses had scores similar to those of generic program graduates. Experience and full-time employment status were significantly associated with higher scores among graduating RN-to-BSN students.
