Rural breast cancer survivors: exercise preferences and their determinants

Is home-based, virtually delivered, group exercise feasible and acceptable for older patients with hepatocellular carcinoma? A non-randomised feasibility study (TELEX-Liver Cancer)

OBJECTIVES

The study aimed to assess the feasibility, acceptability and safety of delivering a home-based telehealth exercise intervention to older patients with hepatocellular carcinoma (HCC).

DESIGN

Non-randomised feasibility study.

SETTING

Patients were recruited from UK outpatient liver cancer clinics.

PARTICIPANTS

Patients were aged ≥60 years with HCC, with post-treatment imaging reporting a complete response, partial response or stable disease.

INTERVENTION AND DATA COLLECTION

Patients were invited to attend synchronous online exercise sessions, twice weekly for 10 weeks. Physical function and patient-reported outcomes were assessed pre-intervention and post-intervention. Qualitative data were collected via semistructured interviews after intervention completion.

PRIMARY OUTCOME MEASURES

Recruitment, retention, exercise adherence and safety.

RESULTS

40 patients were invited to participate and 19 (mean age 74 years) provided consent (recruitment rate 48%). Patients completed 76% of planned exercise sessions and 79% returned to the clinic for follow-up. Hand grip strength (95% CI 1.0 to 5.6), Liver Frailty Index (95% CI -0.46 to -0.23) and time taken to perform five sit-to-stands (95% CI -3.2 to -1.2) improved from pre-intervention to post-intervention. Patients reported that concerns they had relating to their cancer had improved following the intervention (95% CI 0.30 to 5.85). No adverse events occurred during exercise sessions.Qualitative data highlighted the importance of an instructor in real time to ensure that the sessions were achievable, tailored and well balanced, which helped to foster motivation and commitment within the group. Patients reported enjoying the exercise intervention, including the benefits of peer support and highlighted perceived benefits to both their physical and mental health. Patients felt that the online sessions overcame some of the barriers to exercise participation and preferred attending virtual sessions over face-to-face classes.

CONCLUSIONS

It is feasible, acceptable and safe to deliver supervised group exercise via videoconferencing to patients with HCC in their own homes. These findings will inform the design of a future, adequately powered randomised controlled trial to evaluate the efficacy of the intervention.

Remotely delivered exercise to older rural cancer survivors: a randomized controlled pilot trial

PURPOSE

The study aimed to determine the feasibility of remotely delivered exercise (tele-exercise) for older, rural cancer survivors and to explore the effects of tele-exercise on physical function, physical activity, and patient-reported outcomes.

METHODS

Participants were rural cancer survivors age ≥ 60 years (79% female; mean age 70.4 ± 5.7) randomly assigned to the remotely delivered EnhanceFitness (tele-EF) exercise program, inclusive of aerobic, strength, and balance training and led by American Council on Exercise certified instructors for 1 h, 3 days/week for 16 weeks (n = 20) or to a waitlist control group (n = 19). We assessed feasibility, physical function, accelerometer-measured physical activity, and patient-reported outcomes at baseline and post intervention.

RESULTS

Among those screened as eligible, 44 (64%) consented to participate with 39 randomized after completing baseline measures. Attrition was equivalent between groups (n = 1, each) with 95% completing the study. The median class attendance rate was 86.9% (interquartile range: 79-94%). Compared to controls, tele-EF participants had statistically significant improvement in the five-time sit-to-stand test (- 3.4 vs. - 1.1 s, p = 0.03, effect size = 0.44), mean daily light physical activity (+ 38.5 vs 0.5 min, p = 0.03, effect size = 0.72) and step counts (+ 1977 vs. 33, p = 0.01, effect size = 0.96). There were no changes in self-efficacy for exercise, fatigue, or sleep disturbance between groups.

CONCLUSIONS

Findings indicate that tele-EF is feasible in older, rural cancer survivors and results in positive changes in physical function and physical activity.

IMPLICATIONS FOR CANCER SURVIVORS

Tele-EF addresses common barriers to exercise for older, rural cancer survivors, including limited accessible opportunities for professional instruction and supervision.

A psychosocial investigation of exercise preferences in real and virtual environments

Three studies explored exercise preferences in real-world and virtual environments, and their relationship with social physique anxiety (SPA), social comparison, and self-presentational efficacy (SPE). In Study 1 (N = 230), real-world exercise preferences were explored. Study 2 (N = 228) measured preferences for real-world and virtual reality (VR) exercise, and Study 3 (N = 249) investigated preferences for avatar embodiment and virtual companions within VR. Results revealed that participants who preferred home-based exercise had lower exercise behaviour, more negative fitness-related social comparisons, or lower SPE expectancy and outcome value (Study 1). Individuals with lower exercise behaviour, more negative fitness-related social comparisons, lower SPE expectancy, or higher SPA were also more likely to choose VR than real-world exercise (Study 2). In a VR exercise setting, participants with higher SPA and more negative social comparisons also preferred to embody a non-human and fantasy avatar more than a realistic avatar. A heightened threat of negative social comparison when imagining exercise with a physically superior virtual companion resulted in the strongest preference to embody a fantasy avatar (Study 3). The results suggest that individuals who place high importance on self-presentation and have low belief in their capacity to project an image of competence to others, are more likely to prefer exercise contexts that minimise physique- and fitness-related evaluation. Moreover, VR may afford a less psychosocially threatening context for individuals who feel self-conscious or comparatively inferior to others during exercise.

State of research, feasibility, safety, acceptability, and outcomes examined on remotely delivered exercises using technology for older adult with cancer: a scoping review

INTRODUCTION

Technology-based exercise is gaining attention as a promising strategy for increasing physical activity (PA) in older adults with cancer (OACA). However, a comprehensive understanding of the interventions, their feasibility, outcomes, and safety is limited. This scoping review (1) assessed the prevalence and type of technology-based remotely delivered exercise interventions for OACA and (2) explored the feasibility, safety, acceptability, and outcomes in these interventions.

METHODS

Studies with participant mean/median age ≥ 65 reporting at least one outcome measure were included. Databases searched included the following: PubMed, CINAHL, Embase, Cochrane Library Online, SPORTDiscus, and PsycINFO. Multiple independent reviewers completed screening and data abstractions of articles in English, French, and Spanish.

RESULTS

The search yielded 2339 citations after removing duplicates. Following title and abstract screening, 96 full texts were review, and 15 were included. Study designs were heterogeneous, and sample sizes were diverse (range 14-478). The most common technologies used were website/web portal (n = 6), videos (n = 5), exergaming (n = 2), accelerometer/pedometer with video and/or website (n = 4), and live-videoconferencing (n = 2). Over half (9/15) of the studies examined feasibility using various definitions; feasibility outcomes were reached in all. Common outcomes examined include lower body function and quality of life. Adverse events were uncommon and minor were reported. Qualitative studies identified cost- and time-savings, healthcare professional support, and technology features that encourage engagement as facilitators.

CONCLUSION

Remote exercise interventions using technology appear to be feasible and acceptable in OACA.

IMPLICATIONS FOR CANCER SURVIVORS

Some remote exercise interventions may be a viable way to increase PA for OACA.

Breast cancer survivors' exercise preferences change during an exercise intervention are associated with post-intervention physical activity

PURPOSE

Exercise program preferences are important for designing physical activity (PA) interventions; yet may change following an intervention. Further, the relationship between preferences and PA behavior change is unclear. This study evaluated exercise program preferences among breast cancer survivors (BCS) before and after a behavioral intervention and associations between program preferences and PA change.

METHODS

BCS were randomized to the BEAT Cancer intervention (n = 110) or written materials (n = 112). Questionnaires assessed exercise program preferences. Minutes per week of moderate-to-vigorous PA (MVPA) were accelerometer-measured and self-reported at baseline (M0), post-intervention (M3), and 3-month follow-up (M6).

RESULTS

At M0, the majority of intervention group participants preferred exercising with others (62%) yet shifted to preferring exercising alone (59%) at M3 (p < 0.001). Furthermore, preferring exercising with others at M0 was associated with greater increases in self-reported MVPA between M0 and M6 (124.2 ± 152 vs. 53.1 ± 113.8, p = 0.014). BCS preferring facility-based exercise decreased after the BEAT Cancer intervention (14% vs. 7%, p = 0.039) and preferring exercising at home/had no preference at M0 had greater improvements in accelerometer-measured MVPA from M0 to M3 (74.3 ± 118.8 vs. -2.3 ± 78.4, p = 0.033) and M0 to M6 (44.9 ± 112.8 vs. 9.3 ± 30.4, p = 0.021). Exercise program preferences regarding mode of counseling, training supervision, and type of exercise changed from M0 to M3 but were not associated with changes in MVPA.

CONCLUSION

Findings suggest BCS exercise program preferences may change after an intervention and be associated with changes in MVPA. Understanding the role of PA preferences will better inform the design and success of PA behavior change interventions. ClinicTrials.gov, ClinicalTrials.gov number: NCT00929617.

"I'm Hooked on e-cycling, I Can Finally Be Active Again": Perceptions of e-cycling as a Physical Activity Intervention during Breast Cancer Treatment

Electrically-assisted bicycles (e-bikes) are a means through which to increase individual physical activity (PA) and overcome some commonly reported barriers to engaging in conventional cycling. Fatigue is a common side effect to breast cancer treatment, and the rate of PA engagement drops significantly following a breast cancer diagnosis. The aim of this qualitative study was to examine perceptions of e-cycling as a means of increasing PA in this population. Twenty-four participants (mean age = 57.88 (standard deviation 10.8), 100% female) who have had a breast cancer diagnosis, completed two semi-structured interviews via Zoom. One interview was conducted prior to an e-bike taster session and a second, after the session. Taster sessions were conducted by certified cycling instructors in the community. Interviews were conducted between December 2021 and May 2022. Data were transcribed verbatim and analyzed thematically using NVivo 12 software. An inductive and deductive approach to analysis was adopted. Five themes were generated: (1) Perceived role of e-bikes during treatment, (2) The relationship between e-bikes and fatigue, (3) Cancer-specific considerations, (4) Is e-cycling 'enough'?, and (5) Optimizing the intervention. Negative perceptions of e-bikes noted before the taster session were altered following riding an e-bike. The multiple levels of assistance made cycling manageable and less impacted by fatigue, thereby enabling individuals to re-establish previous cycling habits. E-cycling may be a suitable option to increase PA behavior amongst individuals being treated for breast cancer, with the potential to overcome many of the barriers of conventional cycling. Enabling this population to trial an e-bike elicits positive physical and psychological responses that may help to promote future engagement.

Relationships between Obesity, Exercise Preferences, and Related Social Cognitive Theory Variables among Breast Cancer Survivors

Breast cancer survivors with obesity have an increased risk of cancer recurrence, second malignancy, and comorbidities. Though physical activity (PA) interventions are needed, investigation of the relationships between obesity and factors influencing PA program aspects among cancer survivors remain understudied. Thus, we conducted a cross-sectional study examining associations amongst baseline body mass index (BMI), PA program preferences, PA, cardiorespiratory fitness, and related social cognitive theory variables (self-efficacy, exercise barriers interference, social support, positive and negative outcome expectations) from a randomized controlled PA trial with 320 post-treatment breast cancer survivors. BMI was significantly correlated with exercise barriers interference (r = 0.131, p = 0.019). Higher BMI was significantly associated with preference to exercise at a facility (p = 0.038), lower cardiorespiratory fitness (p < 0.001), lower walking self-efficacy (p < 0.001), and higher negative outcome expectations (p = 0.024), independent of covariates (comorbidity score, Western Ontario and McMaster Universities osteoarthritis index score, income, race, education). Those with class I/II obesity reported a higher negative outcome expectations score compared with class III. Location, walking self-efficacy, barriers, negative outcome expectations, and fitness should be considered when designing future PA programs among breast cancer survivors with obesity.

Narrative Review of Sex Differences in Muscle Strength, Endurance, Activation, Size, Fiber Type, and Strength Training Participation Rates, Preferences, Motivations, Injuries, and Neuromuscular Adaptations

ABSTRACT

Nuzzo, JL. Narrative review of sex differences in muscle strength, endurance, activation, size, fiber type, and strength training participation rates, preferences, motivations, injuries, and neuromuscular adaptations. J Strength Cond Res 37(2): 494-536, 2023-Biological sex and its relation with exercise participation and sports performance continue to be discussed. Here, the purpose was to inform such discussions by summarizing the literature on sex differences in numerous strength training-related variables and outcomes-muscle strength and endurance, muscle mass and size, muscle fiber type, muscle twitch forces, and voluntary activation; strength training participation rates, motivations, preferences, and practices; and injuries and changes in muscle size and strength with strength training. Male subjects become notably stronger than female subjects around age 15 years. In adults, sex differences in strength are more pronounced in upper-body than lower-body muscles and in concentric than eccentric contractions. Greater male than female strength is not because of higher voluntary activation but to greater muscle mass and type II fiber areas. Men participate in strength training more frequently than women. Men are motivated more by challenge, competition, social recognition, and a desire to increase muscle size and strength. Men also have greater preference for competitive, high-intensity, and upper-body exercise. Women are motivated more by improved attractiveness, muscle "toning," and body mass management. Women have greater preference for supervised and lower-body exercise. Intrasexual competition, mate selection, and the drive for muscularity are likely fundamental causes of exercise behaviors in men and women. Men and women increase muscle size and strength after weeks of strength training, but women experience greater relative strength improvements depending on age and muscle group. Men exhibit higher strength training injury rates. No sex difference exists in strength loss and muscle soreness after muscle-damaging exercise.

Exercise program preferences regarding mode of counseling, training supervision, and type of exercise changed from M0 to M3 but were not associated with changes in MVPA. Conclusion Findings suggest BCS exercise program preferences may change after an intervention and be associated with changes in MVPA. Understanding the role of PA preferences will better inform the design and success of PA behavior change interventions. ClinicTrials.gov, ClinicalTrials.gov number: NCT00929617.

The feasibility and acceptability of a home-based, virtual exercise intervention for older patients with hepatocellular carcinoma: protocol for a non-randomised feasibility study (TELEX-Liver Cancer)

BACKGROUND

The number of incident cases and deaths from primary liver cancer, predominantly hepatocellular carcinoma (HCC), has increased markedly in the last two decades. HCC is generally diagnosed at an advanced stage, and most new cases are in people aged over 70 years with age-related comorbidities. Treatment options are often limited, with most patients receiving palliative treatment or supportive care only. As a consequence, maintaining quality of life (QoL) through symptom management is critically important and is a core objective of clinical care. Strong evidence supports the efficacy of supervised exercise training for addressing certain cancer-related symptoms, including QoL, physical function, and fatigue. However, there are many barriers to implementing supervised exercise programmes within cancer care pathways, including economic pressures on healthcare systems and personal barriers for patients. Recent advances in technology allow patients to exercise at home under the 'virtual' supervision of an exercise professional through videoconferencing software (termed 'telehealth exercise'). Despite its potential, there are uncertainties relating to the feasibility, acceptability, and safety of telehealth exercise in people living with HCC.

METHODS

This is a protocol for a prospective, single-centre, single-arm, pretest-posttest feasibility trial. We aim to recruit 20 patients aged 60 years or older who have received treatment for HCC and are undergoing routine clinical monitoring. Patients will be invited to take part in two online, home-based, group exercise sessions per week for 10 consecutive weeks. The 'virtual' exercise sessions will be delivered in real time by an exercise professional through videoconferencing software. Each session will comprise 30 min of aerobic and resistance exercise performed at a moderate intensity, as guided by the 10-point Borg rating of perceived exertion scale. Feasibility outcomes include recruitment, retention, adherence, intervention fidelity, and safety. Acceptability of the intervention will be assessed using a mixed-methods approach via monthly online surveys and an exit telephone interview. Physical function, accelerometry-measured physical activity, mid-upper arm circumference, and patient-reported outcome measures (PROMS) will be assessed before and after the intervention to determine the feasibility of assessing outcome measures. Physical function outcomes include the short physical performance battery and Liver Frailty Index. PROMS include the Functional Assessment of Cancer Therapy-Hepatobiliary questionnaire, Functional Assessment of Chronic Illness Therapy-Fatigue questionnaire, Activities-specific Balance Confidence scale, Hospital Anxiety and Depression Scale, and the Godin Leisure-Time Exercise Questionnaire.

DISCUSSION

This mixed-methods study will address uncertainties relating to the feasibility and acceptability of delivering live, online, home-based, group exercise sessions to patients with HCC. The findings will inform whether any modifications are required to refine and optimise the intervention, and the assessment of outcome measures will provide information on the likely size and variability of intervention effects. Collectively, the data generated will inform the design of a subsequent, adequately powered, randomised controlled trial to evaluate the efficacy of the telehealth exercise intervention.

Characterizing the Exercise Behaviour, Preferences, Barriers, and Facilitators of Cancer Survivors in a Rural Canadian Community: A Cross-Sectional Survey

Barriers, facilitators, and motivators to exercise for cancer survivors living in urban settings are well described in the literature. However, there is a lack of comparable information for cancer survivors living in rural communities. We describe the exercise behaviours, barriers, facilitators, and motivators to exercise participation of cancer survivors living in a rural Canadian community. Adult cancer survivors with a primary address in a rural region of Ontario, Canada, who had visited a community hospital in the previous five years were mailed a cross-sectional survey assessing current exercise volume (minutes of moderate-to-vigorous aerobic and resistance exercise), as well as exercise preferences, barriers, and facilitators. Seventy-two survivors (mean age 65 years) completed the survey (16% response rate). A majority of respondents were diagnosed with breast cancer (49%) in the last 5 years (61%). Aerobic- and resistance-training guidelines for cancer survivors were met by 38% and 10% of respondents, respectively. Physical side effects were the most common barrier to exercise during treatment (65%) and post-treatment (35%). Being unaware of available exercise programs, time for exercise, distance to exercise services, and cost were commonly reported barriers during and post-treatment (reported by 10–22%). Respondents reported needing information from a qualified exercise professional (46%), access to a gym (33%) and exercise equipment (26%), and social support (25%) to facilitate exercise participation. Consistent with urban-based cancer survivors, most rural survivors surveyed in this study were not meeting the physical-activity guidelines and reported numerous exercise barriers. These findings can serve as a resource for this and similar rural communities when developing community-based exercise-support services for cancer survivors.

Remote interventions to improve exercise behaviour in sedentary people living with and beyond cancer: a systematic review and meta-analysis

BACKGROUND

The COVID-19 pandemic has forced many cancer services to consider a transition to a remote format of delivery that is largely untested. Accordingly, we sought to perform a systematic review of the effects of remotely delivered interventions to improve exercise behaviour in sedentary adults living with and beyond cancer.

METHODS

Eligible studies were randomised controlled trials comparing a remotely delivered exercise intervention to a usual care comparison in sedentary people over 18 years old with a primary cancer diagnosis. Nine electronic databases were searched from inception to November 2020.

RESULTS

The review included three trials, totalling 186 participants. Two of the included trials incorporated prescriptions that meet current aerobic exercise recommendations, one of which also meets the guidelines for resistance exercise. No trials reported an intervention adherence of 75% or more for a set prescription that meets current exercise guidelines.

CONCLUSION

There is little evidence suggesting that remote exercise interventions promote exercise behaviours or improve physical function in sedentary adults living with and beyond cancer. The development and evaluation of novel remote exercise interventions is needed to establish their usefulness for clinical practice. Given the social response to the COVID-19 pandemic, further research in this area is urgently needed.

Determining patient needs to enhance exercise program implementation and uptake in rural settings for women after a cancer diagnosis

PURPOSE

To qualitatively explore exercise barriers and facilitators experienced by rural female cancer survivors from the program interventionist and recipient perspective for the purpose of enhancing exercise program implementation and uptake in rural settings.

METHODS

A descriptive qualitative study design was utilized. Focus groups were conducted prior to implementation of an evidence-based exercise program by a rural non-research cancer clinical site. Nineteen rural female cancer survivors (mean age = 61.7 ± 10.9 years) and 11 potential interventionists (mean age = 42.3 ± 15.3 years) completed focus groups (stratified by participant role). Focus groups were audio recorded, transcribed, coded, and analyzed using inductive thematic analysis with NVivo 11.

RESULTS

Cancer survivors identified 12 barrier themes (cancer specific adverse effects, lack of support, lack of knowledge, perceived negative aspects of exercise, cost, lack of resources, motivation, inconvenience, lack of program flexibility, time, weather, safety) and eight facilitator themes (knowledge, ease of access, resources, awareness, cost, options, organized, fun) related to exercise. Interventionists identified seven barrier themes (cost, transportation, lack of cancer survivor and interventionist knowledge, fear, motivation, lack of support, lack of resources) and four facilitator themes (resources, support, knowledge, motivation). Narratives revealed differing role-specific perspectives on shared themes between survivors and interventionists as well as potential implementation strategies for enhancing exercise participation and exercise program uptake among rural female cancer survivors.

CONCLUSION

Exploring multi-level stakeholder perspectives on cancer survivors' exercise needs and related strategies yields important information for organizations to consider when implementing exercise programs in rural contexts.

Preferência de exercícios de indivíduos acometidos pelo acidente vascular cerebral usuários da atenção básica de saúde

RESUMO Indivíduos acometidos pelo acidente vascular cerebral (AVC) tendem a manter um padrão sedentário de vida com nível de atividade física insuficiente, gerando limitações funcionais, restrição na participação e dificuldade de envolvimento em programas de exercícios. Compreender a preferência de exercícios desta população é importante para o entendimento dos fatores contextuais e a adequação de programas voltados à promoção de saúde e funcionalidade. Trata-se de um estudo transversal com amostra de conveniência, cujos objetivos foram identificar a preferência de exercícios de indivíduos na fase crônica do AVC usuários do Sistema Único de Saúde em Belo Horizonte, (MG), Brasil, e investigar a associação com o grau de comprometimento motor, velocidade de marcha, nível de atividade física e qualidade de vida. A preferência de exercícios foi avaliada pelo Questionário de Preferência de Exercícios(AVC)-Brasil. Foram entrevistados 24 indivíduos (59±15 anos) que reportaram preferência por exercícios realizados em ambientes controlados e ofertados em grupo. Os exercícios favoritos foram a caminhada e o treino de força muscular. Não houve correlação entre a preferência de exercícios e as variáveis investigadas. Identificar a preferência de exercícios desta população pode contribuir para uma melhor assistência à saúde fornecida pelos serviços públicos, além de aumentar a adesão desses indivíduos aos programas de promoção à saúde e funcionalidade.

Rural-urban differences in meeting physical activity recommendations and health status in cancer survivors in central Pennsylvania

PURPOSE

This study explored rural-urban differences in meeting physical activity (PA) recommendations and health status in cancer survivors in central Pennsylvania and associations between PA and health status.

METHODS

Cancer survivors (N = 2463) were identified through a state cancer registry and mailed questionnaires assessing PA and health status. Rural-urban residence was based on county of residence at diagnosis. Participants self-reported frequency and duration of leisure-time PA and were classified as meeting: (1) aerobic recommendations (≥ 150 min/week), (2) muscle-strengthening recommendations (≥ 2 times/week), (3) both aerobic and muscle-strengthening recommendations, or (4) neither recommendation. Logistic regression models examined associations between rural-urban residence and meeting PA recommendations and associations between PA and health status, adjusting for age, cancer type, gender, and income.

RESULTS

Nearly 600 (N = 591, 24.0%) cancer survivors returned completed questionnaires (rural 9.5%, urban 90.5%). Half (50.0%) of rural cancer survivors reported no leisure-time PA compared to 35.2% of urban cancer survivors (p = 0.020), and urban cancer survivors were 2.6 times more likely to meet aerobic PA recommendations (95% CI 1.1-6.4). Odds of reporting good physical and mental health were 2.3 times higher among survivors who reported meeting aerobic recommendations compared to those who did not meet PA recommendations (95% CI 1.1-4.5), adjusting for rurality and covariates.

CONCLUSIONS

Results demonstrate persistent rural-urban differences in meeting PA recommendations in cancer survivors and its association with self-reported health.

IMPLICATIONS FOR CANCER SURVIVORS

Findings underscore the need for interventions to increase PA in rural cancer survivors in an effort to improve health status and reduce cancer health disparities.

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.

"Moving Away From Cancer" Prospective Exercise Trial for Female Rural Cancer Survivors: How Can We Step It Up?

PURPOSE

This prospective trial's objective was to determine feasibility and outcomes of an exercise-based intervention for rural overweight/obese female cancer survivors.

MATERIALS AND METHODS

Survivors of endometrial, breast, or ovarian cancer enrolled in a 6-month program of increased aerobic activity (30 minutes daily walking) and strength-training exercises using exercise bands (THERABAND; Akron, OH) with personalized telephone motivational coaching. Baseline demographics, anthropomorphic measurements, quality of life (QOL), fitness, and readiness to adopt exercise changes were assessed; daily steps, band use, and follow-up measurements were assessed at 3 and 6 months. Study completion was modeled using logistic regression.

RESULTS

The mean age of the 99 women was 59.9 years, the mean body mass index (BMI) was 35.9 kg/m², 88.9% were white, and 41.4% reported current exercise. Fifty-five women (55.6%) completed the 6-month program, and 36 (36.4%) completed exercise interventions. Using logistic regression to model study completion, only baseline QOL scores (physical component summary) and mental component summary) remained significant predictors. The mean weight change was a gain (0.88 kg). Higher MCS baseline scores and prior regular exercise predicted continued exercise and increased step counts, whereas higher BMI and baseline sleep predicted decreased QOL. Top walking barriers were feeling unwell and weather; barriers to strength exercises were band dislike and pain.

CONCLUSION

The most significant predictor of trial completion and improved exercise outcomes was a higher baseline mental QOL. Motivation, belief in the importance of exercise, and prescribed/monitored exercise regimens were not sufficient; supportive and cognitive behavioral therapy interventions for survivors are needed to sustain uptake.

Physical Activity for Oncological Patients in COVID-19 Era: No Time to Relax

Whereas the coronavirus disease 2019 (COVID-19) storm is relentlessly progressing worldwide, a great effort from scientific societies has been made to give recommendations for safely continuing oncological care, prioritizing the interventions according to patients' condition and type and stage of tumor. Nevertheless, to date no specific suggestions regarding physical activity and exercise in cancer patients during the COVID-19 era have been released, neglecting the potential deleterious effects of quarantine and sedentary behaviour (imposed as containment measures against COVID-19), particularly in these subjects. Moreover, literature is constantly consolidating the crucial impact of regular physical activity in cancer in reducing recurrence and mortality risk. In this commentary, we discuss possible adaptations of the recently published exercise guidelines to the current pandemic emergency, proposing various modalities to prevent or mitigate the physical inactivity risk in cancer patients.

Implementation of a Brief Screening Tool to Identify Needs of Breast Cancer Survivors

BACKGROUND

Innovation in health care delivery is needed to improve care for cancer survivors. We report our experience with adapting screening questions from the National Comprehensive Cancer Network (NCCN) guideline to evaluate the needs of breast cancer survivors.

MATERIALS AND METHODS

We adapted the NCCN-recommended screening questions into a plain language, self-administered 1-page intake questionnaire. The tool was administered to a convenience sample of female breast cancer survivors at follow-up oncology and primary care visits. Domains included symptoms, lifestyle concerns, and financial issues. Frequency of concerns was assessed as "never," "rarely," "sometimes," "very frequently," and "always." We evaluated feasibility and utility of administration and the prevalence and frequency of patient-reported concerns.

RESULTS

The questionnaire was highly acceptable to patients and enhanced visits for clinicians. Clinicians reported that it led to discussion of issues that may not otherwise be addressed in the visit and did not find it burdensome. The most commonly endorsed patient concerns were desire to improve fitness or nutrition, worry about cancer recurrence, and insomnia. A majority also reported feeling anxiety and aches or pains in joints or extremities. Several issues known to be underreported in clinic visits were frequently endorsed, included sexual dissatisfaction and memory impairments. Clinicians suggested incorporating the tool into the electronic health record to increase utility and awareness.

CONCLUSION

Screening for individual needs among breast cancer survivors is feasible, efficient, and may identify prevalent issues that otherwise can be missed in routine survivorship care.

Exercise Levels and Preferences in Cancer Patients: A Cross-Sectional Study

BACKGROUND

Despite the benefits related to physical exercise, large numbers of cancer patients are not sufficiently active.

METHODS

To investigate exercise levels and preferences in cancer patients, a cross-sectional study was conducted on a random sample of 392 cancer outpatients who anonymously completed a questionnaire investigating general and medical characteristics, and expressed willingness to participate in exercise programs. Current exercise levels were estimated with the Leisure Score Index (LSI).

RESULTS

Most patients (93%) were insufficiently active but 80% declared an interest in exercise programs. Patients preferred oncologist-instructed programs and specified particular exercise needs. Multivariate logistic regression showed that willingness to exercise was associated with education (OR: 1.87; 95% CI: 1.15-3.04 beyond age 14 years vs. up to 14 years) and current physical activity (OR: 1.92; 95% CI: 1.92-3.63 for sweat-inducing activity >2 times/week vs. <1 time/week). Patients given chemotherapy were less inclined to exercise (OR: 0.45; 95% CI: 0.23-0.86) than those who did not. LSI was lower if cancer stage was advanced (β: -0.36; 95% CI: -0.75 to -0.02) than if it was in remission. High LSI was also associated with longer education, lower BMI, and longer time after diagnosis.

CONCLUSION

Cancer patients are insufficiently active but are willing to participate in personalized exercise programs. Information from this survey may help in designing personalized interventions so these patients will achieve sufficient exercise.

Effect of neuromuscular electrical stimulation on skeletal muscle size and function in patients with breast cancer receiving chemotherapy

Exercise has numerous benefits for patients with cancer, but implementation is challenging because of practical and logistical hurdles. This study examined whether neuromuscular electrical stimulation (NMES) can serve as a surrogate for classic exercise by eliciting an exercise training response in skeletal muscle of women diagnosed with breast cancer undergoing chemotherapy. Patients (n = 22) with histologically confirmed stage I, II, or III breast cancer scheduled to receive neoadjuvant or adjuvant chemotherapy were randomized to 8 wk of bilateral neuromuscular electrical stimulation (NMES; 5 days/wk) to their quadriceps muscles or control. Biopsy of the vastus lateralis was performed at baseline and after 8 wk of intervention to assess muscle fiber size, contractility, and mitochondrial content. Seventeen patients (8 control/9 NMES) completed the trial and were included in analyses. NMES promoted muscle fiber hypertrophy (P < 0.001), particularly in fast-twitch, myosin heavy chain (MHC) IIA fibers (P < 0.05) and tended to induce fiber type shifts in MHC II fibers. The effects of NMES on single-muscle fiber contractility were modest, and it was unable to prevent declines in the function in MHC IIA fibers. NMES did not alter intermyofibrillar mitochondrial content/structure but was associated with reductions in subsarcolemmal mitochondria. Our results demonstrate that NMES induces muscle fiber hypertrophy and fiber type shifts in MHC II fibers but had minimal effects on fiber contractility and promoted reductions in subsarcolemmal mitochondria. Further studies are warranted to evaluate the utility of NMES as an exercise surrogate in cancer patients and other conditions.NEW & NOTEWORTHY This is the first study to evaluate whether neuromuscular electrical stimulation (NMES) can be used as an exercise surrogate to improve skeletal muscle fiber size or function in cancer patients receiving treatment. We show that NMES promoted muscle fiber hypertrophy and fiber type shifts but had minimal effects on single-fiber contractility and reduced subsarcolemmal mitochondria.

'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.

Outcomes of a text message, Fitbit, and coaching intervention on physical activity maintenance among cancer survivors: a randomized control pilot trial

PURPOSE

We aimed to determine the effect of a health coach, text message, and Fitbit intervention on moderate-to-vigorous physical activity (MVPA) maintenance in cancer survivors following a supervised exercise program compared to provision of a Fitbit alone.

METHODS

Participants were recruited during the last month of an exercise-based oncology rehabilitation program and randomly assigned to the full intervention (n = 34) or Fitbit-only control groups (n = 32). In total, 59 cancer survivors completed the program (81% female; mean age 61.4 ± 9.0). Group by time differences in accelerometer-measured MVPA was assessed using linear mixed models. Additionally, we examined mean weekly Fitbit-derived MVPA levels.

RESULTS

Intervention participants maintained weekly MVPA from pre- (295.7 ± 139.6) to post-intervention (322.0 ± 199.4; p = 0.37), whereas those in the Fitbit-only group had a significant decrease in MVPA (305.5 ± 181.1 pre vs 250.7 ± 166.5 post; p = 0.03, effect size 0.57). The intervention participants maintained recommended levels of MPVA for health benefits during the 8-week intervention, whereas the Fitbit-only control group did not.

CONCLUSIONS

The findings demonstrate that a remote intervention delivered through health coaching, text messages, and Fitbit can promote maintenance of MVPA after a structured program for cancer survivors. However, use of a Fitbit alone was not sufficient to prevent expected decline in MVPA. Additional research is warranted to examine long-term impacts and efficacy in a more diverse population of cancer survivors.

IMPLICATIONS FOR CANCER SURVIVORS

Use of a wearable tracker alone may not be sufficient for exercise maintenance among cancer survivors after transition to an independent program. Additional planning for relapse prevention is recommended.

Physical activity preferences before and after participation in a 6-month physical activity intervention among women with metastatic breast cancer

OBJECTIVE

This secondary analysis of the ABLE Trial (ClinicalTrials.gov NCT03148886) aimed to assess physical activity preferences before and after a 6-month physical activity intervention for women recently diagnosed with metastatic breast cancer and to investigate demographic and clinical correlates of these preferences.

METHODS

Forty-nine patients participated in the ABLE Trial, a single-arm, unsupervised 6-month physical activity intervention with activity trackers. At baseline and 6 months, physical activity preferences, physical activity level, clinical variables, demographics and social vulnerability were assessed.

RESULTS

At baseline, 49 participants were included, among whom 85% were interested in receiving physical activity counselling and 89% were interested in following a physical activity programme designed for metastatic breast cancer. At the end of the study, more participants preferred practising in a community fitness centre (66%) rather than at home (19% vs. 44% at baseline, p = .03). A higher social vulnerability score and not being treated by chemotherapy at baseline were significantly associated with lower desire to receive physical activity counselling (p = .01 and p = .04 respectively).

CONCLUSIONS

This study will help design future studies within patients with metastatic breast cancer in accordance with their preferences. Designing tailored physical activity interventions according to the participant's preferences may be one key to success for adherence.

Community-based exercise for health promotion and secondary cancer prevention in Canada: protocol for a hybrid effectiveness-implementation study

INTRODUCTION

Cancer care has expanded from a disease-focused, survival-oriented model to an approach that now considers how survivors can live well in the aftermath of intensive therapy, where they may deal with significant changes to their bodies, mental health or emotional well-being. Research evidence supports the benefit of exercise during and following cancer treatments for cancer-related symptoms, physical functioning and fitness, and health-related quality of life. To move this efficacy evidence into practice, we designed and launched a 5-year study to evaluate the relative benefit from implementing a clinic-to-community-based cancer and exercise model of care.

METHODS AND ANALYSIS

A hybrid effectiveness and implementation trial design is being used to evaluate the effectiveness of delivery of community-based exercise and to collect data on implementation of the programme. The study opened in January 2017, with estimated completion by January 2022. The programme will be delivered in seven cities across the province of Alberta, Canada, with sites including three academic institutions, six YMCA locations, Wellspring Edmonton and Calgary, and six municipal fitness centres. Participants are adult cancer survivors (n=2500) from all tumour groups and stages and at any time point along their cancer treatment trajectory, up to 3 years post treatment completion. Survivors take part in a minimum of 60 min of mild-to-moderate intensity full body exercise twice weekly for a 12-week period. The primary effectiveness outcome is the proportion of participants meeting or exceeding 150 min of moderate intensity exercise per week at 1-year follow-up. The Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework will be utilised to capture individual-level and organizational-level impact of the exercise programme at 12 and 24 weeks and 1-year follow-up. The cohort of survivors participating in the study will allow for long-term (>5-year) evaluation of rates of cancer recurrence and secondary cancers beyond the funding period.

ETHICS AND DISSEMINATION

The study was approved by the Health Research Ethics Board of Alberta. The study is funded by Alberta Innovates and the Alberta Cancer Foundation. The study will help to answer critical questions on the effectiveness of cancer-specific community-based exercise programming in both the short-term and the long-term. Collectively, the findings will help to inform the acceptability, adoption, feasibility, reach and sustainability of community-based exercise.

Head and neck cancer survivors' preferences for and evaluations of a post-treatment dietary intervention

BACKGROUND

Dietary preferences vary depending on cancer type. The purpose of this study was to report dietary intervention preferences and a study program evaluation from post-treatment head and neck cancer survivors participating in a dietary intervention.

METHODS

Between January 2015 and August 2016, 24 head and neck cancer survivors participated in a 12-week randomized clinical dietary intervention trial that promoted weekly consumption of 2.5 cups of cruciferous vegetables and 3.5 cups of green leafy vegetables. At study completion, survivors completed a preferences survey and a study program evaluation to probe interests and improvement aspects for planning future dietary intervention trials. Descriptive statistics (means and frequencies) were generated for multiple choice question responses. Responses to open-ended questions were recorded and grouped based on themes, and verified by quality assurance checks by a second study team member.

RESULTS

Twenty-three survivors completed the preferences and evaluation surveys (response rate 96%). Overall, most participants reported a preference for one-on-one telephone counseling from a registered dietitian nutritionist before beginning treatment. Ninety-six percent of participants ranked the overall study program as "very good" to "excellent," and all agreed the objectives of the study were clear, the study staff was helpful and easy to contact, and the registered dietitian nutritionist was knowledgeable.

CONCLUSIONS

Future research and dietary intervention planning for head and neck cancer survivors should focus on strategies to promote one-on-one telephone or other distance-based counseling combined with face-to-face visits, according to survivor preference.

To rest or not to rest-Health care professionals' attitude toward recommending physical activity to their cancer patients

OBJECTIVE

While in the past cancer patients were advised to rest, recent research revealed various beneficial effects of physical activity, including increased treatment tolerability during cancer treatment and prolonged survival, which has led to a paradigm shift in relevant guidelines. This study examined if this paradigm shift from rest to activity has been consolidated in health care professionals' (HCP') attitude. It was investigated if the two dimensions of attitude (rest and activity) are endorsed empirically within the theory of planned behavior (TPB). Differences between physicians and nurses were examined.

METHODS

Five hundred forty seven physicians and 398 nurses treating breast, prostate, or colorectal cancer patients completed a cross-sectional questionnaire. To assess attitude toward physical activity during cancer treatment, we developed a 15-item scale, which included original statements of HCP. TPB variables were assessed.

RESULTS

A factor analysis revealed the proposed distinction of attitude into two dimensions. The activity-paradigm was stronger represented in HCP' attitude compared with rest-paradigm (M_{activity-paradigm}  = 4.1 versus M_{rest-paradigm}  = 2.7, p < 0.001). Additionally, the activity-paradigm had higher exploratory power in explaining intention to recommend physical activity in cancer patients. However, the rest-paradigm was able to explain intention to recommend physical activity over and above activity-paradigm (ΔR²  = 0.05). Nurses had higher scores on the rest-paradigm than physicians.

CONCLUSIONS

The activity-paradigm has already been consolidated in HCP' minds. However, the rest-paradigm is still present in the daily routine of oncology physicians and nurses. Addressing concerns and insecurities related to supporting cancer patients in maintaining or building up a physically active lifestyle is a very important educational task.

Does walking protect against decline in cognitive functioning among breast cancer patients undergoing chemotherapy? Results from a small randomised controlled trial

BACKGROUND

Cancer related cognitive impairments have been subjectively reported and objectively detected in breast cancer patients treated with chemotherapy and are known to have a profound negative impact on productivity, psychosocial well-being and overall quality of life. Moderate levels of walking are known to be of benefit to the psychosocial well-being of those affected by breast cancer and for managing cognitive impairment in healthy adults, children, and the elderly. The purpose of this study is to investigate the effects of a home-based, self-managed, moderate intensity walking intervention on subjective and objective cognitive functioning in breast cancer patients undergoing chemotherapy.

METHODS

A home-based, self-managed intervention that consisted of moderate levels of walking was compared to usual care among breast cancer patients treated with chemotherapy in a randomised controlled trial. Outcome measures included changes in subjective (CFQ) and objectively detected cognitive functioning (Stroop, SART and two subscales from the WAIS- Digit Span and Block Design). Fifty participants were randomised to either the intervention group (n = 25), who completed 12 weeks of moderate intensity walking, or to the control group (n = 25) mid-way through chemotherapy.

RESULTS

Compared with the control group, the self-managed walking intervention had positive effects on perceived cognitive function but not on sustained attention, executive function, memory or visual spatial skills when assessed objectively using neuropsychological measures.

CONCLUSION

This home-based, self-managed intervention is beneficial for protecting against perceived cognitive decline in breast cancer patients treated with chemotherapy. There is a need for further research to objectively assess cognitive decline within this population with larger sample sizes of patients.

Differences in Physical Activity and Diet Patterns between Non-Rural and Rural Adults

Background: It is unclear how rural occupations and lifestyles may play a role in shaping physical activity and diet behaviors that contribute to the rural–urban obesity disparity. Methods: Data come from the prospective and observational South Dakota Rural Bone Health Study, which included adults aged 20–66 years in three groups: (1) non-rural non-Hutterite, (2) rural non-Hutterite, and (3) rural Hutterite. Physical activity data were collected using 7-day physical activity questionnaires, and hours per day in physical activity categories are reported. Diet data were collected using food frequency questionnaires, and food group servings per day (svg/day) are reported. Mixed models were generated to determine group differences in physical activity and diet outcomes, and marginal group means are presented. Results: Among females, both rural groups spent more time in moderate activity (4.8 ± 0.13 h/day and 4.7 ± 0.09 h/day vs. 3.5 ± 0.11 h/day, both p < 0.001) and vigorous activity (0.58 ± 0.03 h/day and 0.53 ± 0.02 h/day vs. 0.43 ± 0.03 h/day, both p < 0.01) and less time sitting (4.4 ± 0.13 h/day and 4.3 ± 0.09 h/day vs. 5.0 ± 0.11 h/day, both p < 0.001) on weekdays than non-rural groups. Hutterite females spent fewer hours in moderate activity (2.6 ± 0.08 h/day vs. 4.5 ± 0.11 h/day, p < 0.001) and vigorous activity (0.18 ± 0.02 h/day vs. 0.46 ± 0.02 h/day, p < 0.001) on weekend days compared to rural females. Hutterite females consumed more fruits (2.2 ± 0.06 svg/day vs. 1.7 ± 0.10 svg/day, p < 0.001) and vegetables (3.6 ± 0.08 svg/day vs. 2.7 ± 0.12 svg/day, p < 0.001) than rural females. Among males, both rural groups spent more time in moderate activity (4.9 ± 0.13 h/day and 6.1 ± 0.12 h/day vs. 3.0 ± 0.16 h/day, both p < 0.001) and less time sitting (4.1 ± 0.13 h/day and 3.4 ± 0.12 h/day vs. 6.0 ± 0.15 h/day, both p < 0.001) on weekdays compared to non-rural groups. Hutterite males spent less time in moderate activity (2.1 ± 0.10 h/day vs. 4.1 ± 0.11 h/day, p < 0.001) and vigorous activity (0.15 ± 0.04 h/day vs. 0.74 ± 0.04 h/day, p < 0.001) on weekend days compared to rural males. Hutterite males consumed more vegetables (3.0 ± 0.10 svg/day vs. 2.0 ± 0.11 svg/day, p < 0.001) than rural males. Conclusions: A rural occupation and lifestyle appear to contribute to differences in physical activity, while traditional rural lifestyle practices contribute to differences in diet.

Which self-management strategies do health care professionals recommend to their cancer patients? An experimental investigation of patient age and treatment phase

This vignette based study aimed to examine recommendations of health care professionals (HCPs) in promoting self-management strategies to cancer patients. Nine-hundred-forty-two physicians and nurses were asked to (1) indicate if they would recommend self-management strategies to a vignette cancer patient, and (2) to specify those in an open format. Vignettes included a manipulation of patient age (60 vs. 75 years) and treatment phase (currently treated versus treatment completed). Six categories emerged through coding a total of 2303 recommendations: physical activity (71.8%), nutrition (64.3%), psychological support (36.7%), medical support (29.2%), conscious living (17.2%) and naturopathy (12.3%). While psychological support was particularly recommended during treatment, physical activity was more frequently recommended after completion of treatment. Results suggest that HCPs recommend a variety of self-management strategies besides standard medical treatment. Patient's treatment phase and age seem to partly influence recommendation behavior, potentially indicating insecurities regarding acute treatment situations and age-related stereotypes.

Barriers to physical activity: a study of academic and community cancer survivors with pain

PURPOSE

Despite the numerous benefits of physical activity (PA) for patients with cancer, many cancer survivors report challenges to participating in PA. The objectives of this study were (1) to assess barriers to PA and (2) to examine participant characteristics associated with modifiable barriers to PA among cancer survivors with pain.

METHODS

We conducted a cross-sectional survey study at one academic medical center and 11 community hospitals. Participants completed the 12-item Physical Activity Barriers After Cancer (PABAC) instrument (Cronbach's alpha = 0.75). Multivariable regression models examined participant characteristics associated with PABAC scores with a higher score indicating more barriers to PA.

RESULTS

Among 662 survivors, 67% had moderate or severe pain (rating 4 or greater on a scale of 0 to 10). Seventy-five percent of survivors did not meet the American Cancer Society PA recommendations on average, and these individuals had higher mean PABAC scores (beta coefficient (β) = 2.02, 95% confidence interval (CI) 0.96-3.09, p < 0.001). In adjusted analyses, cancer survivors who were non-white (β = 1.55, 0.28-2.82, p = 0.02), treated at a community hospital (β = 1.07, 0.09-2.05, p = 0.03), had surgery (β = 1.69, 0.69-2.69, p = 0.001), or within 12 months of diagnosis (β = 1.15, 0.20-2.10, p = 0.02) reported greater barriers to PA.

CONCLUSIONS

The majority of cancer survivors with pain are not adequately participating in PA. Key demographic and clinical characteristics are associated with survivors' barriers.

IMPLICATIONS FOR CANCER SURVIVORS

Efforts to overcome specific barriers are needed to promote PA after a cancer diagnosis.

Are healthcare professionals being left in the lurch? The role of structural barriers and information resources to promote physical activity to cancer patients

PURPOSE

Although many cancer patients benefit from physical activity (PA), healthcare professionals (HCP) still do not promote it routinely. Including different groups of HCP, this study aimed to examine how structural barriers are perceived as impeding by HCP for promoting PA to cancer patients, how the perceptions of structural barriers are associated with promoting PA, and how HCP react to information resources.

METHODS

A total of 287 physicians in outpatient care, 242 physicians in inpatient care, and 388 oncology nurses completed our questionnaire (paper-pencil or online). Participants assessed nine different structural barriers (on a 4-point Likert Scale) and reported their PA promotion frequency. Further, they could request three different kinds of information resources about PA in oncological settings.

RESULTS

Across professional groups, more than 70% of HCP indicated that they promoted PA to their cancer patients often or routinely. Oncology nurses indicated that they were more impeded in promoting PA by six structural barriers than physicians (all p < .01). "Not enough time per patient" and "lack of an expert contact person" were associated with a reduced PA promotion in two professional groups (all p < .05). Information resources were requested by 69.5% of the participants: mostly physicians working in outpatient care and especially by those perceiving structural barriers.

CONCLUSIONS

Although a big proportion of HCP reported that they frequently promoted PA, our findings suggest that HCP still perceive structural barriers. The perception and influence of structural barriers differed between professional groups, pointing to the importance of profession specific guidance.

Physical activity programming and counseling preferences among cancer survivors: a systematic review

BACKGROUND

Physical activity (PA) participation and adherence among cancer survivors is low, despite research indicating numerous physical, psychological and emotional health benefits of exercise. Tailoring exercise programs specific to the PA preferences in cancer survivors has merit for increasing PA participation and adherence to accrue these benefits. This systematic review identifies and differentiates PA programming and counseling preferences of adult cancer survivors across various cancer survivor groups.

METHODS

PubMed, SPORTDiscus, Scopus, PsycINFO, EMBASE, Web of Science and CINAHL were electronically searched (inception to Oct 2017) and articles were identified using PRISMA guidelines. Two reviewers independently assessed identified articles to determine eligibility and then individually performed a quality assessment on all final studies. Extracted and analyzed data included participant characteristics, interest in exercise counseling and programming, as well as specific exercise and counseling preferences (e.g. location, timing, intensity).

RESULTS

Forty-one articles were included in this systematic review. Most studies assessed mixed cancer survivor groups or breast cancer survivors. Most cancer survivors felt able and interested in participating in a PA program, though starting a PA program after or before treatment was preferred. Walking was the strongest PA modality preference, and most cancer survivors preferred moderate intensity PA. Cancer survivors also indicated preferences for home-based PA that could take place in the morning. Slight preferences were found towards physical activity counseling delivered by a fitness expert from a cancer center. Both quantitative and qualitative studies were found to be of moderate to high quality based on the Appraisal Tool for Cross-Sectional Studies (AXIS) and the Consolidated Criteria for Reporting Qualitative Research (COREQ), respectively.

CONCLUSION

Cancer survivors have an interest in participating in PA programs with walking as the primary modality. Additionally, morning-based PA programs that can be tapered to home-based programs are desirable. However, there was wide variation in other PA preference variables, suggesting multiple program options would be beneficial. Many cancer survivors felt interested and able to participate in PA, and therefore designing PA programs that are tailored to cancer survivors is integral for optimizing recruitment and adherence, as well as enhancing health outcomes in cancer survivors.

Physical activity referral to cardiac rehabilitation, leisure centre or telephone-delivered consultations in post-surgical people with breast cancer: a mixed methods process evaluation

BACKGROUND

Physical activity (PA) programmes effective under 'research' conditions may not be effective under 'real-world' conditions. A potential solution is to refer patients to existing PA community-based PA services.

METHODS

A process evaluation of referral of post-surgical patients with early-stage breast cancer to cardiac rehabilitation exercise classes, leisure centre with 3-month free leisure centre membership or telephone-delivered PA consultations for 12 weeks. Quantitative data were collected about PA programme uptake and reach, patient engagement with the PA programme, delivery and fidelity and PA dose. Qualitative data were collected about patient experiences of taking part in the PA programmes. Audio-recorded qualitative interviews of participants about the programmes were analysed thematically. Quantitative data were reported descriptively using means and SD.

RESULTS

In Phase I, 30% (n = 20) of eligible patients (n = 20) consented, 85% (n = 17) chose referral to leisure centre, and 15% (n = 3) chose cardiac rehabilitation. In Phase II, 32% (n = 12) consented, 25% (n = 3) chose leisure centre and 75% (n = 9) chose telephone-delivered PA consultations. Walking at light intensity for about an hour was the most common PA. All Phase I participants received an induction by a cardiac rehabilitation physiotherapist or PA specialist from the leisure centre but only 50% of Phase II participants received an induction by a PA specialist from the leisure centre. Four themes were identified from qualitative interviews about programme choice: concerns about physical appearance, travel distance, willingness to socialise and flexibility in relation to doing PA. Four themes were identified about facilitators and barriers for engaging in PA: feeling better, feeling ill, weight management, family and friends.

CONCLUSIONS

The current community-based PA intervention is not yet suitable for a definitive effectiveness randomised controlled trial. Further work is needed to optimise PR programme reach, PA dose and intervention fidelity.

Connecting people with cancer to physical activity and exercise programs: a pathway to create accessibility and engagement

Recent guidelines concerning exercise for people with cancer provide evidence-based direction for exercise assessment and prescription for clinicians and their patients. Although the guidelines promote exercise integration into clinical care for people with cancer, they do not support strategies for bridging the guidelines with related resources or programs. Exercise program accessibility remains a challenge in implementing the guidelines, but that challenge might be mitigated with conceptual frameworks ("pathways") that connect patients with exercise-related resources. In the present paper, we describe a pathway model and related resources that were developed by an expert panel of practitioners and researchers in the field of exercise and rehabilitation in oncology and that support the transition from health care practitioner to exercise programs or services for people with cancer. The model acknowledges the nuanced distinctions between research and exercise programming, as well as physical activity promotion, that, depending on the available programming in the local community or region, might influence practitioner use. Furthermore, the pathway identifies and provides examples of processes for referral, screening, medical clearance, and programming for people after a cancer diagnosis. The pathway supports the implementation of exercise guidelines and should serve as a model of enhanced care delivery to increase the health and well-being of people with cancer.

A turning point: Head and neck cancer patients' exercise preferences and barriers before and after participation in an exercise intervention

This study examined the exercise barriers and preferences of head and neck cancer (HNC) survivors in relation to exercise experience. Participants (n = 22; 46.8% response rate) completed retrospective self-report questionnaires on demographic and medical information, exercise barriers and preferences. A subset of participants then completed semi-structured interviews (n = 18). Participants had previously engaged in the ENHANCE trial during, or immediately following, radiation treatment, an average of 22.1 ± 5.8 months before. Retrospective questionnaires revealed that before ENHANCE participation, lack of interest and time were the primary exercise barriers. After participation, there was a significant decrease in typical barriers including lack of interest (p = .008), exercise not a priority (p = .039) and exercise not in routine (p = .004). Number of barriers experienced after ENHANCE participation was negatively correlated with age, quality of life and minutes of resistance exercise training per week. After ENHANCE participation, significant increases were found in preference for exercising at a cancer centre (p = .031) and with other cancer survivors (p = .016). Four higher order themes emerged inductively from interview data analysis pertaining to preferences (i.e., class format) and three higher order themes regarding barriers (physical, psychological and external). By investigating participants' perspectives after ENHANCE participation, key factors for effective HNC exercise programme design were identified.

Weight management and physical activity throughout the cancer care continuum

Mounting evidence suggests that weight management and physical activity (PA) improve overall health and well being, and reduce the risk of morbidity and mortality among cancer survivors. Although many opportunities exist to include weight management and PA in routine cancer care, several barriers remain. This review summarizes key topics addressed in a recent National Academies of Science, Engineering, and Medicine workshop entitled, "Incorporating Weight Management and Physical Activity Throughout the Cancer Care Continuum." Discussions related to body weight and PA among cancer survivors included: 1) current knowledge and gaps related to health outcomes; 2) effective intervention approaches; 3) addressing the needs of diverse populations of cancer survivors; 4) opportunities and challenges of workforce, care coordination, and technologies for program implementation; 5) models of care; and 6) program coverage. While more discoveries are still needed for the provision of optimal weight-management and PA programs for cancer survivors, obesity and inactivity currently jeopardize their overall health and quality of life. Actionable future directions are presented for research; practice and policy changes required to assure the availability of effective, affordable, and feasible weight management; and PA services for all cancer survivors as a part of their routine cancer care.

Cross-cultural adaptation and measurement properties of the Brazilian version of the Exercise Preference Questionnaire(stroke)

BACKGROUND

The Exercise Preference Questionnaire (EPQ(stroke)) captures exercise preferences and measures personal factors, that influence motivation and adherence to exercise in stroke subjects.

OBJECTIVES

To perform the cross-cultural adaptation of the EPQ(stroke) into the Brazilian-Portuguese language and to evaluate its measurement properties.

METHODS

The EPQ(stroke) was cross-culturally adapted and primarily tested in 30 chronic stroke subjects. After the final version of the EPQ(stroke)-Brazil was created, its test-retest reliability was verified, using Kappa indices and intra-class correlation coefficients (ICCs) (n=50), and internal consistency was verified using Cronbach's alpha coefficients (n=101). Construct validity was assessed using exploratory factor analysis (n=101), content validity using the content validity index (CVI) (n=8), and face validity using the rate of agreement regarding the clarity, wording, ability to answer the questions, and lay-out and style of the questionnaire with two groups, including individuals with stroke (n=81) and multidisciplinary health professionals (n=32).

RESULTS

The pre-final version required revisions (items 9, 29, and 30) and, after another pre-test, it was shown to be appropriate. The Kappa indices ranged from 0.58 to 0.95; the ICCs from 0.35 to 0.93, and the Cronbach's alpha coefficient was 0.82 (0.768-0.869 CI), showing adequate internal consistency. The exploratory factor analysis and CVI confirmed the validity of the EPQ(stroke)-Brazil. The rate of agreement was greater than 80% for both groups.

CONCLUSION

The EPQ(stroke)-Brazil was found to be a valid and reliable measure for verifying exercise preferences of Brazilian individuals with stroke.

Breast cancer survivors' preferences for technology-supported exercise interventions

PURPOSE

The purpose of this study was to explore breast cancer survivors' interest in and preferences for technology-supported exercise interventions.

METHODS

Post-treatment survivors [n = 279; M _age = 60.7 (SD = 9.7)] completed a battery of online questionnaires in August 2015. Descriptive statistics were calculated for all data. Logistic regression analyses were conducted to examine relationships between survivors' interest in a technology-supported exercise interventions and demographic, disease, and behavioral factors. These same factors were examined in relation to perceived effectiveness of such interventions using multiple regression analyses.

RESULTS

About half (53.4%) of survivors self-reported meeting public health recommendations for physical activity. Fewer than half reported using an exercise or diet mobile app (41.2%) or owning an activity tracker (40.5%). The majority were interested in receiving remotely delivered exercise counseling (84.6%), participating in a remotely delivered exercise intervention (79.5%), and using an exercise app or website (68%). Survivors reported that the most helpful technology-supported intervention components would be an activity tracker (89.5%), personalized feedback (81.2%), and feedback on how exercise is influencing mood, fatigue, etc. (73.6%). Components rated as least helpful were social networking integration (31.2%), group competitions (33.9%), and ability to see others' progress (35.1%).

CONCLUSIONS

Preferences for technology-supported exercise interventions varied among breast cancer survivors. Nonetheless, data indicate that technology-supported interventions may be feasible and acceptable. Engaging stakeholders may be important in developing and testing potential intervention components.

Developing the Stroke Exercise Preference Inventory (SEPI)

BACKGROUND

Physical inactivity is highly prevalent after stroke, increasing the risk of poor health outcomes including recurrent stroke. Tailoring of exercise programs to individual preferences can improve adherence, but no tools exist for this purpose in stroke.

METHODS

We identified potential questionnaire items for establishing exercise preferences via: (i) our preliminary Exercise Preference Questionnaire in stroke, (ii) similar tools used in other conditions, and (iii) expert panel consultations. The resulting 35-item questionnaire (SEPI-35) was administered to stroke survivors, along with measures of disability, depression, anxiety, fatigue and self-reported physical activity. Exploratory factor analysis was used to identify a factor structure in exercise preferences, providing a framework for item reduction. Associations between exercise preferences and personal characteristics were analysed using multivariable regression.

RESULTS

A group of 134 community-dwelling stroke survivors (mean age 64.0, SD 13.3) participated. Analysis of the SEPI-35 identified 7 exercise preference factors (Supervision-support, Confidence-challenge, Health-wellbeing, Exercise context, Home-alone, Similar others, Music-TV). Item reduction processes yielded a 13-item version (SEPI-13); in analysis of this version, the original factor structure was maintained. Lower scores on Confidence-challenge were significantly associated with disability (p = 0.002), depression (p = 0.001) and fatigue (p = 0.001). Self-reported barriers to exercise were particularly prevalent in those experiencing fatigue and anxiety.

CONCLUSIONS

The SEPI-13 is a brief instrument that allows assessment of exercise preferences and barriers in the stroke population. This new tool can be employed by health professionals to inform the development of individually tailored exercise interventions.

Fee-for-service cancer rehabilitation programs improve health-related quality of life

BACKGROUND

Rigorously applied exercise interventions undertaken in a research setting result in improved health-related quality of life (hrqol) in cancer survivors, but research to demonstrate effective translation of that research to practice is needed. The objective of the present study was to determine the effect of fee-for-service cancer rehabilitation programs in the community on hrqol and on self-reported physical activity and its correlates.

METHODS

After enrolment and 17 ± 4 weeks later, new clients (n = 48) to two fee-for-service cancer rehabilitation programs completed the 36-Item Short Form Health Survey (rand-36: rand Corporation, Santa Monica, CA, U.S.A.), the Godin Leisure-Time Exercise Questionnaire, and questions about physical activity correlates. Normal fee-for-service operations were maintained, including a fitness assessment and individualized exercise programs supervised in a group or one-on-one setting, with no minimum attendance required. Fees were associated with the assessment and with each exercise session.

RESULTS

Of the 48 participants, 36 (75%) completed both questionnaires. Improvements in the physical functioning, role physical, pain, and energy/fatigue scales on the rand-36 exceeded minimally important differences and were of a magnitude similar to improvements reported in structured, rigorously applied, and free research interventions. Self-reported levels of vigorous-intensity (p = 0.021), but not moderate-intensity (p = 0.831) physical activity increased. The number of perceived barriers to exercise (p = 0.035) and the prevalence of fatigue as a barrier (p = 0.003) decreased. Exercise self-efficacy improved only in participants who attended 11 or more sessions (p = 0.002). Exercise enjoyment did not change (p = 0.629).

CONCLUSIONS

Enrolment in fee-for-service cancer rehabilitation programs results in meaningful improvements in hrqol comparable to those reported by research interventions, among other benefits. The fee-for-service model could be an effective model for delivery of exercise to more cancer survivors.

Design of a randomised intervention study: the effect of dumbbell exercise therapy on physical activity and quality of life among breast cancer survivors in Malaysia

BACKGROUND

Participation in physical activity has a positive impact on the overall health and quality of life, whereas physical inactivity is associated with a poor prognosis among breast cancer survivors. Despite the health-enhancing benefits of physical activity, the majority of Malaysian breast cancer survivors are not physically active. This paper presents the design of a randomised study to evaluate the feasibility and effect of exercise therapy intervention using light resistance dumbbell exercise to promote active lifestyle and improve the quality of life of breast cancer survivors in Malaysia.

METHODS/DESIGN

This is an intervention study of a 12-week exercise therapy that will explore and compare the effects of light resistance and aerobic exercise on physical activity level and quality of life components in 102 female breast cancer survivors. Major eligibility criteria include histologically confirmed diagnosis of breast cancer stages I-III, 3-12 months post-diagnosis, and absence of any disorder contraindicating exercise. Participants will be stratified based on menopausal status (pre-menopause vs post-menopause) and then assigned randomly to one of three groups. Participants in group A will participate in a three-times weekly supervised resistance exercise using light resistance dumbbells; participants in group B will participate in a three-times weekly supervised aerobic exercise; while participants in group C (control group) will be given aerobic exercise after completion of the intervention. The primary end points include physical activity level and quality of life components. The secondary end points are body mass index, body composition, total caloric intake, and waist-to-hip ratio.

DISCUSSION

Although there have been many studies of resistance exercise in breast cancer survivors, this is the first study using this specific mode of resistance. Findings will contribute data on the feasibility and effects of light resistance dumbbell exercises, and provide knowledge on the physical activity intervention programme that will maximally promote better overall health and well-being of survivors.

Factors Influencing Amount of Weekly Exercise Time in Colorectal Cancer Survivors

BACKGROUND

Performing regular exercise of at least 150 minutes weekly has benefits for colorectal cancer survivors. However, barriers inhibit these survivors from performing regular exercise.

OBJECTIVES

The aim of this study was to explore exercise behaviors and significant factors influencing weekly exercise time of more than 150 minutes in colorectal cancer survivors.

METHODS

A cross-sectional study design was used to recruit participants in Taiwan. Guided by the ecological model of health behavior, exercise barriers were assessed including intrapersonal, interpersonal, and environment-related barriers. A multiple logistic regression was used to explore the factors associated with the amount of weekly exercise.

RESULTS

Among 321 survivors, 57.0% of them had weekly exercise times of more than 150 minutes. The results identified multiple levels of significant factors related to weekly exercise times including intrapersonal factors (occupational status, functional status, pain, interest in exercise, and beliefs about the importance of exercise) and exercise barriers related to environmental factors (lack of time and bad weather). No interpersonal factors were found to be significant.

CONCLUSIONS

Colorectal cancer survivors experienced low levels of physical and psychological distress. Multiple levels of significant factors related to exercise time including intrapersonal factors as well as exercise barriers related to environmental factors should be considered.

IMPLICATIONS FOR PRACTICE

Healthcare providers should discuss with their patients how to perform exercise programs; the discussion should address multiple levels of the ecological model such as any pain problems, functional status, employment status, and time limitations, as well as community environment.

Pancreatic cancer survivors' preferences, barriers, and facilitators related to physical activity and diet interventions

PURPOSE

To conduct a telephone survey establishing pancreatic cancer survivors' level of interest in, preferences for, and perceived barriers and facilitators to participating in exercise and diet intervention programming. These data will inform the development of such interventions for newly-diagnosed patients.

METHODS

Seventy-one survivors treated for resectable pancreatic adenocarcinoma from October 2011 to August 2014 were identified through an institutional cancer registry and contacted via telephone. A telephone survey was conducted to query survivors' level of interest in, preferences for, and perceived barriers and facilitators to participating in an exercise and dietary intervention program shortly after disease diagnosis. Acceptability of a technology-based visual communication (e.g., Skype™, FaceTime®) intervention was also assessed.

RESULTS

Fifty participants completed the survey (response rate 71.8 %). Over two-thirds of participants reported interest in exercise and diet intervention programming. Over half reported comfort with a technology-delivered visual communication intervention. Barriers to participation included older age and physical, personal, and emotional problems. The most common facilitator was program awareness. Outcomes for future research important to participants were supportive care and quality of life.

CONCLUSIONS

Most pancreatic cancer patients are interested in exercise and diet interventions shortly after diagnosis; however, some barriers to program participation exist.

IMPLICATIONS FOR CANCER SURVIVORS

Future research and intervention planning for pancreatic cancer survivors should focus on developing messaging and strategies that provide support for survivorship outcomes, increase survivor awareness, address lack of familiarity with technology, reduce fears about potential barriers, and help survivors overcome these barriers. In so doing, survivorship needs can be better met and quality of life improved in this understudied population.
