The promoting physical activity in regional and remote cancer survivors (PPARCS) trial: Physical activity maintenance.

INTRODUCTION: The study examined whether increased physical activity (PA) in nonmetropolitan cancer survivors was maintained 12 weeks following the PPARCS intervention. METHODS: PA outcomes were assessed using an accelerometer at baseline, end of the intervention, and at 24 weeks. Linear mixed models were used to examine between-group changes in PA outcomes. RESULTS: The increased moderate-to-vigorous PA (MVPA) following intervention was maintained with significantly higher MVPA in the intervention group at 24 weeks (vs. controls) compared to baseline nett change of 52.5 min/week (95% CI 11.0-94.0.4). CONCLUSIONS: Distance-based interventions using wearables and health coaching may produce MVPA maintenance amongst nonmetropolitan cancer survivors.

Safety, feasibility and effectiveness of the remotely delivered Pulmonary Hypertension and Home-Based (PHAHB) physical activity intervention.

Background: Pulmonary hypertension (PH) is a heterogeneous condition, associated with a high symptom burden and a substantial loss of exercise capacity. Despite prior safety concerns regarding physical exertion, exercise training as a supportive therapy is now recommended for PH patients. Currently, most programmes are hospital-based, which limits accessibility. There is a need to provide alternative approaches for physical activity engagement for PH patients. The aim of this research was to develop, implement and evaluate the safety, feasibility and effectiveness of home-based physical activity intervention for PH. Methods: An entirely remotely delivered home-based physical activity intervention underpinned by behaviour change theory and informed by end-users, was assessed using a single-arm feasibility study design. Participants (n=19; 80% female) with a mean±sd age of 49.9±15.9 years with a diagnosis of PH undertook a 10-week, home-based physical activity intervention with induction training, support materials, telecommunication support, health coaching, exercise training and assessments, all remotely delivered. Training involved respiratory training along with a combination of aerobic and resistance exercises. Results: The intervention was deemed safe as no adverse events were reported. A high level of feasibility was demonstrated as the protocol was implemented as intended, sustained a high level of engagement and adherence and was well accepted by participants in terms of enjoyment and utility. There was a significant improvement in functional capacity, physical activity, exercise self-efficacy and quality of life, between baseline and post-training. Conclusion: The study demonstrates that an entirely remotely delivered home-based physical activity programme is safe, feasible and effective in improving functional capacity, physical activity and quality of life in PH patients.

A randomized controlled trial of Promoting Physical Activity in Regional and Remote Cancer Survivors (PPARCS).

BACKGROUND: Physical activity (PA) is important for cancer survivors. Trials of remotely delivered interventions are needed to assist in reaching under-served non-metropolitan cancer survivors. The objective of this study was to ascertain whether wearable technology, coupled with health coaching was effective in increasing PA in breast and colorectal cancer survivors living in regional and remote areas in Australia. METHODS: Cancer survivors from 5 states were randomized to intervention and control arms. Intervention participants were given a Fitbit Charge 2TM and received up to 6 telephone health coaching sessions. Control participants received PA print materials. Accelerometer assessments at baseline and 12 weeks measured moderate-to-vigorous PA (MVPA), light PA, and sedentary behavior. RESULTS: Eighty-seven participants were recruited (age = 63 ± 11 years; 74 (85%) female). There was a significant net improvement in MVPA of 49.8 min/week, favoring the intervention group (95% confidence interval (95%CI): 13.6-86.1, p = 0.007). There was also a net increase in MVPA bouts of 39.5 min/week (95%CI: 11.9-67.1, p = 0.005), favoring the intervention group. Both groups improved light PA and sedentary behavior, but there were no between-group differences. CONCLUSION: This is the first study to demonstrate that, when compared to standard practice (i.e., PA education), a wearable technology intervention coupled with distance-based health coaching, improves MVPA in non-metropolitan cancer survivors. The results display promise for the use of scalable interventions using smart wearable technology in conjunction with phone-based health coaching to foster increased PA in geographically disadvantaged cancer survivors.

Experiences and facilitators of physical activity engagement amongst colorectal and endometrial cancer survivors: the Wearable Activity Technology and Action-Planning (WATAAP) trial.

PURPOSE: This study explored colorectal and endometrial cancer survivors' experiences of participation in a wearable intervention and the dimensions that influenced intervention engagement and physical activity behaviour change. METHODS: Semi-structured interviews (n= 23) were conducted with intervention participants (mean age 65.8 (SD ±7.1) and analysed using thematic analysis. RESULTS: Four main themes were identified: (i) commitment, (ii) accountability and monitoring, (iii) routine, (iv) Fitbit as health coach. Those that assigned a higher priority to PA were more likely to schedule PA and be successful in PA change. Those less successful presented more barriers to change and engaged in more incidental PA. The Fitbit acting as health coach was the active ingredient of the intervention. CONCLUSIONS: Commitment evidenced through prioritising PA was the foundational dimension that influenced PA engagement. Interventions that foster commitment to PA through increasing the value and importance of PA would be worthwhile. Wearables holds great promise in PA promotion and harnessing the technique of discrepancy between behaviour and goals is likely a valuable behaviour change technique.

Exploration of physical activity knowledge, preferences and support needs among pulmonary hypertension patients.

OBJECTIVE: Physical activity (PA) is an established adjunct therapy for pulmonary hypertension (PH) patients to mitigate PH symptoms and improve quality of life. However, PA engagement within this population remains low. This study investigated PH patients' knowledge of PA, recalled advice, exercise preferences and PA support needs. METHODS: Semi-structured interviews were conducted with 19 adults (mean age 50 years; SD ±12 years) diagnosed with PH, living in Ireland. Interview scripts were digitally recorded and transcribed verbatim. Thematic analysis was used to analyse the data. RESULTS: Four key themes were identified: Lack of PA knowledge; exercise setting preference; accountability and monitoring; and clinician delivered PA information and guidance. CONCLUSION: This study found that PH clinicians provide suboptimal PA advice, yet patients desired clinician-delivered PA guidance. Home-based exercise was preferred with monitoring and external accountability deemed as important to facilitate sustained engagement. PRACTICE IMPLICATIONS: PH clinicians are well positioned to play a critical role in assisting and empowering PH patients to engage in PA. Providing training and education to PH clinicians regarding exercise prescription may be beneficial. Further research is needed to evaluate the feasibility and efficacy of home-based exercise interventions to improve quality of life and physical activity in PH.

Predicting physical activity change in cancer survivors: an application of the Health Action Process Approach.

PURPOSE: Previous research has not examined the utility of the Health Action Process Approach (HAPA) to predict physical activity (PA) change in cancer survivors. The aim of the study was to investigate the efficacy of a HAPA-based model in predicting temporal change in moderate-to-vigorous physical activity (MVPA) in cancer survivors. METHODS: Participants enrolled in the Wearable Activity Technology and Action Planning (WATAAP) trial completed validated questionnaires (n = 64) to assess HAPA constructs (action and maintenance self-efficacy, outcome expectancies, action planning, risk perceptions, and intention) and wore an ActiGraph to measure PA at baseline, 12 weeks, and 24 weeks later. Data were analyzed using variance-based structural equation modeling with residualized change scores for model variables. RESULTS: Consistent with predictions, changes in action self-efficacy (ß = 0.490, p < 0.001, ES = 0.258) and risk perceptions (ß = 0.312, p = 0.003, ES = 0.099) were statistically significant predictors of intention change over time. Changes in intention (ß = 0.217, p = 0.029, ES = 0.040) and action planning (ß = 0.234, p = 0.068, ES = 0.068) predicted changes in MVPA. Overall, the model accounted for significant variance in intention (R2 = 0.380) and MVPA (R2 = 0.228) change. CONCLUSIONS: Changes in intention and action planning were important correlates of MVPA change over 24 weeks. Further, changes in action self-efficacy and risk perceptions predicted changes in intention. IMPLICATIONS FOR CANCER SURVIVORS: interventions that foster risk perceptions and self-efficacy, strengthen intentions, and promote action planning may be effective in promoting sustained PA change in cancer survivors.

"It is the fear of exercise that stops me" - attitudes and dimensions influencing physical activity in pulmonary hypertension patients.

Pulmonary hypertension is a progressive cardiorespiratory disease that is characterized by considerable morbidity and mortality. While physical activity can improve symptoms and quality of life, engagement in this population is suboptimal. The aim of this study was to explore attitudes towards exercise and the dimensions that influence physical activity participation in individuals with pulmonary hypertension. Virtual, semi-structured interviews were conducted with individuals, with a formal diagnosis of pulmonary hypertension. Participants were recruited through the Pulmonary Hypertension Association of Ireland. Interviews were transcribed and analysed using thematic analysis. Nineteen patients were interviewed (n = 19). There was a female preponderance (n = 13) and the mean age was 50 ± 12 years. Three themes were identified and included fear, perceived value of exercise and environmental factors. Fear was the primary theme and included three sub-themes of fear of (i) over-exertion, (ii) physical damage and (iii) breathlessness. The perceived value of exercise encompassed two distinct sub-themes of perceived (i) exercise importance and (ii) benefits of exercise. Environmental factors included the terrain, weather conditions and location. Fear of overexertion, harm and dyspnoea strongly influenced attitudes to and engagement in physical activity. This study revealed heterogenous patient perspectives regarding the importance of physical activity and exercise. Future interventions that mitigate fear and promote the value of physical activity for individuals with pulmonary hypertension may have considerable benefits in promoting physical activity engagement. Such interventions require multidisciplinary involvement, including specialised pulmonary hypertension clinicians and exercise and behaviour change specialists.

The wearable activity technology and action-planning trial in cancer survivors: Physical activity maintenance post-intervention.

OBJECTIVES: The study objective was to assess whether moderate-to-vigorous intensity physical activity (MVPA) change in cancer survivors (n = 68, mean age = 64 years) was maintained 12-weeks following the Wearable Activity Technology and Action Planning (WATAAP) intervention. Secondary aims were to assess the effects of the intervention on blood pressure (BP) and body mass index (BMI), and to explore group differences between baseline and 24-weeks. DESIGN: Randomized controlled trial. METHODS: MVPA and sedentary behaviour were assessed using an accelerometer at baseline, the end of the intervention (12-weeks), and at 24-weeks. Generalised linear mixed models with random effects were used to examine between-group and within-group changes in MVPA, sedentary behaviour, BP and BMI. RESULTS: MVPA was significantly higher in the intervention group compared with the control group at 24-weeks following adjustment for known confounders (141.4 min/wk. (95% CI = 9.1 to 273.8), p = 0.036). At 24-weeks participants in the intervention group had maintained their increased levels of MVPA (change from 12-weeks = 8.8 min/wk.; 95% CI = -43 to 61; p = 0.74). The reduction in MVPA in the control group over the first 12-weeks was also maintained at 24-weeks (5.4 min/wk.; 95% CI = -3.6 to 4.6; p = 0.80). Secondary outcomes did not differ between groups at 24-weeks. CONCLUSIONS: Our results suggest distance-based interventions using wearable technology produce increases in MVPA that endure at least 12-weeks after the intervention is completed.

Pulmonary hypertension and home-based (PHAHB) exercise intervention: protocol for a feasibility study.

INTRODUCTION: Novel therapies for pulmonary hypertension (PH) have improved survival and slowed disease progression. However, patients still present with symptoms of exertional dyspnoea and fatigue, which impacts their ability to perform activities of daily living, reduces exercise tolerance and impairs their quality of life (QoL). Exercise training has shown to be safe and effective at enhancing QoL and physical function in PH patients, yet it remains an underused adjunct therapy. Most exercise training for PH patients has been offered through hospital-based programmes. Home-based exercise programmes provide an alternative model that has the potential to increase the availability and accessibility of exercise training as an adjunct therapy in PH. The purpose of this study is to investigate the feasibility, acceptability, utility and safety of a novel remotely supervised home-based PH exercise programme. METHODS: Single arm intervention with a pre/post comparisons design and a follow-up maintenance phase will be employed. Eligible participants (n=25) will be recruited from the Mater Misericordiae University Hospital PH Unit. Participants will undergo a 10-week home-based exercise programme, with induction training, support materials, telecommunication support and health coaching sessions followed by a 10-week maintenance phase. The primary outcomes are feasibility, acceptability, utility and safety of the intervention. Secondary outcomes will include the impact of the intervention on exercise capacity, physical activity, strength, health-related QoL and exercise self-efficacy. ETHICS AND DISSEMINATION: Ethics approval has been obtained from the Mater Misericordiae Institutional Review Board REF:1/378/2032 and Dublin City University Research Ethics DCUREC/2018/246. A manuscript of the results will be submitted to a peer-reviewed journal and results will be presented at conferences, community and consumer forums and hospital research conferences. TRIAL REGISTRATION NUMBER: ISRCTN83783446; Pre-results.

Factors influencing physical activity in adults with cystic fibrosis.

BACKGROUND: Physical activity (PA) is a well-documented and accepted adjunct therapy for the maintenance and improvement of long-term health in cystic fibrosis (CF). Although the benefits of PA for CF populations are well-established, adherence to PA programmes within this population remains low. This study aimed to investigate the factors that influence engagement in physical activity, and to explore exercise preferences, among adults with cystic fibrosis (CF). METHODS: Semi-structured telephone interviews were conducted. Participants were twenty-one adults (mean age 35 years, SD ± 8) with an established diagnosis of CF, living in Ireland. Interview scripts were digitally recorded and transcribed verbatim. Thematic analysis was used to analyse the data. RESULTS: Four main themes emerged: barriers, motives, value of exercise-related outcomes, and exercise preferences. The main barriers included: low energy levels, time, the weather, and exercise-related confidence. Enjoyment and perceived competence underpinned autonomous motivation. Participants who self-identified as being regularly active valued personally identified exercise-related outcomes such as, accomplishment and affect regulation. Participants indicated a preference for home-based physical activity programs compared to gym- or facility-based programs. CONCLUSION: Interventions aimed at promoting physical activity among adults with CF should involve programs that foster autonomous motivation, enjoyable activities, personally identified outcomes, competence and that can be conducted from the home environment. CLINICAL IMPLICATIONS: To increase physical activity participation among adults with CF, interventions that can be conducted from the home environment, that pay attention to the patients' personally-valued exercise outcomes may be required.

The role of foodbanks in the context of food insecurity: Experiences and eating behaviours amongst users.

The study aim was to investigate the role of foodbanks in the context of food insecurity and explore food choices and eating behaviours amongst users. Food insecurity is associated with poor diet quality and obesity; however, the dimensions that influence food choices and eating behaviour remain unclear. Face-to-face interviews were conducted with individuals who had visited a faith-based foodbank in Perth, Western Australia. Participants were thirty-three service users who had collected a food hamper from the foodbank. Interview transcripts were analyzed using thematic analysis. Four main themes emerged: Ties you over until pay day; Food hamper supporting meals and fruit and vegetable consumption; Food choices supplementing hamper; Household gatekeeping and food control. Participants were complimentary about the content of the food hamper received which included a variety of fresh produce. A key new finding was the frequent purchase and consumption of meat and processed meat to supplement the food hamper provision. Future work and interventions to improve eating behaviour and reduce food-related financial pressure for those vulnerable to food insecurity include further exploration of the dimensions influencing food choices (i.e., cultural norms, habits, symbols); exposure to healthy and tasty plant-based meals, (i.e., tasting low-cost and tasty vegetable-based meals); parenting training focused on handling child/partner food choice influences, and, enforcing household rules governing food.

Psychological correlates of physical activity and exercise preferences in metropolitan and nonmetropolitan cancer survivors.

OBJECTIVE: Interventions to increase physical activity (PA) in cancer survivors have often adopted a "one-size-fits-all" approach and may benefit from being tailored to psychological constructs associated with behavior. The study objective was to investigate the exercise preferences and psychological constructs related to PA among cancer survivors. METHODS: Posttreatment colorectal, endometrial, and breast cancer survivors (n = 183) living in metropolitan and nonmetropolitan areas completed survey measures of PA, exercise preferences, attitudes, self-efficacy, perceived behavioral control (PBC), and intention toward PA. RESULTS: A structural equation model with adequate fit and quality indices revealed that instrumental attitude and self-efficacy were related to PA intention. Intention was related to behavior and mediated the relationship between self-efficacy and behavior. Preferred exercise intensity was related to self-efficacy, PBC, attitudes, and intention, while preferred exercise company was related to self-efficacy and PBC. Participants preferred moderate-intensity PA (71%), specifically self-paced (52%) walking (65%) in an outdoor environment (58%). CONCLUSIONS: Since instrumental attitude and self-efficacy were associated with PA, incorporating persuasive communications targeting attitudes in PA interventions may promote PA participation. As cancer survivors who prefer low-intensity exercise and exercising with others report lower self-efficacy and PBC, interventions targeting confidence and successful experience in this group may also be warranted.

"To be there for my family" and "Keep my independence": Metropolitan and Non-Metropolitan Cancer Survivors' Health Behaviour Motives.

PURPOSE: Cancer survivors are at risk of comorbidities and mortality, and those living outside of metropolitan areas are particularly susceptible given poorer socioeconomic, health and support resources. As engagement in health behaviours is affected by participants' autonomous motives, investigation of the motives of cancer survivors in metropolitan and non-metropolitan areas could elucidate the values and reasons for practising health behaviours, allowing programs to be tailored to these motives. METHODS: Metropolitan (n = 103) and non-metropolitan (n = 80) Australian cancer survivors completed a survey item by describing their motives for physical activity and healthy diet change. Inductive thematic analysis of responses was performed to establish themes across health behaviour motives. RESULTS: Analyses revealed four themes: to be able to, longevity, psychological health and appearance. Survivors primarily referred to being able to enjoy family, leisure activities, travel and staying independent, with these motives often linked to longevity. Motives were similar across locations; however, those in non-metropolitan locations reported continuation of work and pain relief more frequently. Female survivors more often reported weight loss. CONCLUSIONS: A predominant motive for health behaviour change in cancer survivors across geographical location was the ability to enjoy family and engage in leisure and work activities. Programs aiming to promote health behaviours in cancer survivors might consider framing interventions accordingly by emphasizing benefits of longevity and maintaining independence.

Fitbit wear-time and patterns of activity in cancer survivors throughout a physical activity intervention and follow-up: Exploratory analysis from a randomised controlled trial.

OBJECTIVE: There has been growing interest in the use of smart wearable technology to promote physical activity (PA) behaviour change. However, little is known concerning PA patterns throughout an intervention or engagement with trackers. The objective of the study was to explore patterns of Fitbit-measured PA and wear-time over 24-weeks and their relationship to changes in Actigraph-derived moderate-to-vigorous PA (MVPA). METHODS: Twenty-nine intervention participants (88%) from the wearable activity technology and action-planning (WATAAP) trial in colorectal and endometrial cancer survivors accepted a Fitbit friend request from the research team to permit monitoring of Fitbit activity. Daily steps and active minutes were recorded for each participant over the 12-week intervention and throughout the follow-up period to 24-weeks. Accelerometer (GT9X) derived MVPA was assessed at end of intervention (12-weeks) and end of follow-up (24-weeks). RESULTS: Fitbit wear-time over the 24-weeks of data was remarkably consistent, with median adherence score of 100% for all weeks. During the intervention, participants recorded a median 8006 steps/day. Daily step count was slightly increased through week-13 to week-24 with a median of 8191 steps/day (p = 0.039). Actigraph and Fitbit derived measures were highly correlated but demonstrated poor agreement overall. Fitbit measured activity was closest to MVPA measured using Freedson cut-points as no bias was observed. CONCLUSIONS: Step count was maintained throughout the trial displaying promise for the effectiveness of smart-wearable interventions to reduce sedentary behaviour beyond the intervention period. Further worthwhile work should compare more advanced smart-wearable technology with accelerometers in order to improve agreement and explore less resource-intensive methods to assess PA that could be scalable.

Predicting intention to participate in self-management behaviors in patients with Familial Hypercholesterolemia: A cross-national study.

RATIONALE: Familial Hypercholesterolemia (FH) is a genetic condition that predisposes patients to substantially increased risk of early-onset atherosclerotic cardiovascular disease. FH risks can be minimized through regular participation in three self-management. BEHAVIORS: physical activity, healthy eating, and taking cholesterol lowering medication. OBJECTIVE: The present study tested the effectiveness of an integrated social cognition model in predicting intention to participate in the self-management behaviors in FH patients from seven countries. METHOD: Consecutive patients in FH clinics from Australia, Hong Kong, Brazil, Malaysia, Taiwan, China, and UK (total N = 726) completed measures of social cognitive beliefs about illness from the common sense model of self-regulation, beliefs about behaviors from the theory of planned behavior, and past behavior for the three self-management behaviors. RESULTS: Structural equation models indicated that beliefs about behaviors from the theory of planned behavior, namely, attitudes, subjective norms, and perceived behavioral control, were consistent predictors of intention across samples and behaviors. By comparison, effects of beliefs about illness from the common sense model were smaller and trivial in size. Beliefs partially mediated past behavior effects on intention, although indirect effects of past behavior on intention were larger for physical activity relative to taking medication and healthy eating. Model constructs did not fully account for past behavior effects on intentions. Variability in the strength of the beliefs about behaviors was observed across samples and behaviors. CONCLUSION: Current findings outline the importance of beliefs about behaviors as predictors of FH self-management behaviors. Variability in the relative contribution of the beliefs across samples and behaviors highlights the imperative of identifying sample- and behavior-specific correlates of FH self-management behaviors.

'If I Had Someone Looking Over My Shoulder ': Exploration of Advice Received and Factors Influencing Physical Activity Among Non-metropolitan Cancer Survivors.

BACKGROUND: There are significant geographic inequalities in cancer survival with poorer survival rates in non-metropolitan areas compared to major cities. Physical activity (PA) can reduce cancer recurrence and prevent cardiovascular disease. However, few survivors participate in sufficient PA and the prevalence of inactivity is significantly higher in non-metropolitan survivors. The study investigated non-metropolitan survivors' recollections regarding PA advice received following cessation of active treatment, their knowledge of PA guidelines, and the factors that impact on PA behaviour change. METHOD: Sixteen individuals (14 women and 2 men) with breast (n = 8), endometrial (n = 4) or colorectal cancer (n = 4), with a mean age of 60 years (SD = 12) completed semi-structured interviews as part of a larger study to examine the acceptability and utility of wearable trackers to increase PA. Interviews explored survivors' recollections regarding the advice they received concerning PA following active treatment, knowledge of PA guidelines for cancer survivors and the influences on PA behaviour change. Interview transcripts were analysed using thematic analysis. RESULTS: Four main themes emerged: (i) insufficient knowledge of guidelines, (ii) support from the treating oncology team, (iii) external accountability, and (iv) barriers to PA. CONCLUSIONS: Survivors' knowledge of PA guidelines was limited and they did not often recall their oncologists making specific recommendations concerning PA. Survivors' referred to the desire for accountability and monitoring in order to successfully change PA. Lack of motivation was the main barrier to PA participation. Other barriers included age, health status, and lack of facilities or exercise programs.

Promoting physical activity in regional and remote cancer survivors (PPARCS) using wearables and health coaching: randomised controlled trial protocol.

INTRODUCTION: Physically active cancer survivors have substantially less cancer recurrence and improved survival compared with those who are inactive. However, the majority of survivors (70%-90%) are not meeting the physical activity (PA) guidelines. There are also significant geographic inequalities in cancer survival with poorer survival rates for the third of Australians who live in non-metropolitan areas compared with those living in major cities. The primary objective of the trial is to increase moderate-to-vigorous PA (MVPA) among cancer survivors living in regional and remote Western Australia. Secondary objectives are to reduce sedentary behaviour and in conjunction with increased PA, improve quality of life (QoL) in non-metropolitan survivors. Tertiary objectives are to assess the effectiveness of the health action process approach (HAPA) model variables, on which the intervention is based, to predict change in MVPA. METHODS AND ANALYSIS: Eighty-six cancer survivors will be randomised into either the intervention or control group. Intervention group participants will receive a Fitbit and up to six telephone health-coaching sessions. MVPA (using Actigraph), QoL and psychological variables (based on the HAPA model via questionnaire) will be assessed at baseline, 12 weeks (end of intervention) and 24 weeks (end of follow-up). A general linear mixed model will be used to assess the effectiveness of the intervention. ETHICS AND DISSEMINATION: Ethics approval has been obtained from St John of God Hospital Subiaco (HREC/#1201). We plan to submit a manuscript of the results to a peer-reviewed journal. Results will be presented at conferences, community and consumer forums and hospital research conferences. TRIAL REGISTRATION NUMBER: ACTRN12618001743257; pre-results, U1111-1222-5698.

A randomized controlled trial of WATAAP to promote physical activity in colorectal and endometrial cancer survivors.

OBJECTIVE: The objective of this study was to ascertain whether wearable technology coupled with action planning was effective in increasing physical activity (PA) in colorectal and endometrial cancer survivors at cardiovascular risk. METHODS: Sixty-eight survivors who had cardiovascular risk factors and were insufficiently active were randomized to intervention and control arms. Intervention participants were given a wearable tracker for 12 weeks, two group sessions, and a support phone call. Participants in the control arm received print materials describing PA guidelines. Assessments at baseline and 12 weeks measured triaxial and uniaxial estimates of moderate-vigorous physical activity (MVPA), sedentary behaviour, blood pressure, and body mass index (BMI). RESULTS: The intervention group significantly increased MVPA by 45 min/wk compared with a reduction of 21 min/wk in the control group. Group by time interactions were significant for minutes of MVPA (F1,126  = 5.14, P = 0.025). For those with diastolic hypertension, there was a significant group by time interaction (F1,66  = 4.89, P = 0.031) with a net reduction of 9.89 mm Hg in the intervention group. CONCLUSIONS: Significant improvements in MVPA were observed following the intervention. The results display promise for the use of pragmatic, low-intensity interventions using wearable technology.

Exploration of young adults' influences on, and consequences of, avoiding alcohol consumption.

BACKGROUND: There is a wealth of research on motives for alcohol consumption among young people. However, little is known about motives to avoid alcohol in this population. OBJECTIVES: The study purpose was to explore what influences young adults' decisions to avoid alcohol and their motives to avoid alcohol. METHODS: Face-to-face, semi-structured, one-on-one interviews were conducted in 2015 with young adults (n = 30, Mage = 21.13 years, SD = 2.05) living in Australia who did not consume alcohol regularly. Interviews were analyzed using thematic content analysis. RESULTS: Thematic analysis resulted in seven themes: being in control; avoiding negative health consequences; taste; socialization influences; being left out; peer pressure; strategies to curb excessive alcohol consumption. Conclusions/Importance: Findings from the present study contribute to the literature in identifying coping strategies that participants adopted when faced with questions concerning their abstinence. The data provide evidence that, even in a minority, strong identities and beliefs appear to be a robust means to counteract pressure to conform to the social norm to consume alcohol. Findings may inform the (1) development of youth-centered interventions that target values and social norms to help build resistance to pressures to consume alcohol from peers and the wider community and (2) creation of opportunities and promotion of activities that are fun and alcohol free.

Psychological responses, muscle damage, inflammation, and delayed onset muscle soreness to high-intensity interval and moderate-intensity continuous exercise in overweight men.

We compared in-task affect to HIIE and MICE, and its relationship with time spent at different metabolic domains, perceived exertion (RPE), self-efficacy, enjoyment, and future intention of exercise in overweight inactive men. Muscle damage and soreness, and inflammation were assessed post-exercise. Fifteen participants (28.9 ±â€¯5.0 yr; 29.2 ±â€¯3.8 kg/m2) completed a HIIE (10 × 1 min at 100% Vmax, 1 min recovery) and MICE (20 min at 55-59% VO2reserve) session. Affect, alertness, RPE, and self-efficacy were assessed in-task, and enjoyment and future intention post-task. At baseline, 24 and 48 h, creatine kinase, lactate dehydrogenase, interleukin-6 and -10, tumor necrosis factor alpha, and muscle soreness were assessed. Affect (-3.1 ±â€¯1.8 vs. 0.8 ±â€¯1.8, P < .001) and self-efficacy (70 ±â€¯15 vs. 90 ±â€¯15%, P < .001) were lower, while RPE and alertness were higher in HIIE compared to MICE (Ps ≤ .02). Affect was negatively correlated with RPE in HIIE (r = -0.90) and MICE (r = -0.72), and time spent above respiratory compensation point in HIIE (r = -0.59). Affect was positively correlated with self-efficacy in MICE (r = 0.74). Enjoyment, future intention, muscle damage and soreness, and inflammation were similar between HIIE and MICE post-exercise. Therefore, in-task HIIE was experienced as unpleasant compared to MICE, but the psychological and physiological responses post-task were similar in overweight inactive men.
