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.

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.

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.

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.

Factors influencing non-participation in an exercise program and attitudes towards physical activity amongst cancer survivors.

PURPOSE: The purposes of this study are to investigate factors influencing non-participation in a structured exercise program for cancer survivors and to explore survivors' experiences and attitudes in relation to physical activity participation. METHODS: Face-to-face or telephone interviews were conducted with individuals who had registered for, or engaged in, the 'Life Now' exercise program run by Cancer Council Western Australia. Participants were 20 cancer survivors (mean age 63.90 years, SD 15.29) who had either cancelled their registration or withdrawn from the exercise program during the preceding 2 years. Interview transcripts were analysed using thematic analysis. RESULTS: Seven main themes emerged: availability of the program; access, time and cost; lack of motivation or confidence; unwell or fatigued; physical activity preferences; knowledge of physical activity guidelines; and lack of referral or advice. The main barriers were contextual and included availability of, and access to, the program. Participants expressed a preference for home-based physical activity. CONCLUSIONS: Interventions aimed at promoting physical activity in cancer survivors should offer home-based programs and include referral and advice from oncologists. IMPLICATIONS FOR CANCER SURVIVORS: Increasing cancer survivors' participation in, and compliance with, exercise programs may require home-based strategies and referrals from oncologists to allied health professionals to individualise care.

Barriers to physical activity participation in colorectal cancer survivors at high risk of cardiovascular disease.

BACKGROUND: Lifestyle factors including inadequate physical activity may contribute to increased risk of developing cardiovascular disease in colorectal cancer survivors. Identification of the barriers to physical activity is important for forming an evidence base of factors to target in future physical activity programs aimed at improving cardiovascular health in this population. METHODS: Colorectal cancer survivors (N = 24) from St. John of God Subiaco Hospital participated in semi-structured interviews about their current physical activity behaviors and perceived barriers to physical activity. RESULTS: Inductive thematic analysis of interviews revealed 5 overarching themes relating to barriers to physical activity: psychological barriers, environmental barriers, knowledge of guidelines, lack of practitioner support, and energy/age barriers. CONCLUSIONS: Novel findings revealed participants' dependence on practitioner support, including a reliance on practitioners to recommend lifestyle change. Survivors also revealed that regular checkups to monitor cardiovascular risk replaced the need for healthy lifestyle changes. IMPLICATIONS: With survivors holding the advice of clinicians in high regard, an opportunity exists for clinicians to facilitate lifestyle change. Health care professionals such as nurses can implement motivational strategies and provide additional health information during follow-up visits, to ensure long-term adherence. Individuals who reported psychological, motivational, and environmental barriers may benefit from interventions to improve self-regulation, planning, and problem-solving skills.

A qualitative study exploring health perceptions and factors influencing participation in health behaviors in colorectal cancer survivors.

PURPOSE: The purpose of the study was to explore colorectal cancer survivors' health perceptions following cessation of active treatment for cancer and to explore the factors influencing participation in health-promoting behaviors that may help reduce cardiovascular disease risk. METHODS: Face-to-face interviews were conducted with participants that had completed active treatment for cancer within the previous 2 years. Participants were colorectal cancer survivors (N = 24, men = 11, women = 13, M age = 69.38 years, SD = 4.19) recruited from a private hospital in Perth, Australia on the basis that they had existing morbidities that put them at increased risk of cardiovascular disease. Interview transcripts were analyzed using thematic analysis. RESULTS: Five main themes emerged: back to normal; the pleasures in life: 'is it worth it?'; beliefs about health behavior; skepticism of eating guidelines; and lack of motivation. The majority of participants felt they were in good health and had made a full recovery. Participants questioned whether it was worth changing their lifestyle given their life stage and referred to the desire to enjoy life. Lay health beliefs, skepticism of eating guidelines, and a lack of motivation were barriers to change. CONCLUSIONS: Interventions should target lay beliefs and skepticism in relation to health behaviors in order to reinforce the importance and value of participating in health-related behavior. IMPLICATIONS FOR CANCER SURVIVORS: Findings may inform the development of effective, patient-centered interventions that target lay health beliefs and build motivation for health behavior change.

Impact of the Promoting Physical Activity in Regional and Remote Cancer Survivors intervention on health-related quality of life in breast and colorectal cancer survivors.

Background: The PPARCS trial examined the efficacy of a distance-based wearable and health coaching intervention to increase physical activity (PA) in breast and colorectal cancer (CRC) survivors living in non-metropolitan areas. This paper examines the effects of the intervention on health-related quality of life (HRQoL) at 12 weeks (T2; end of intervention) and 24 weeks (T3; follow-up). Methods: Participants that were insufficiently physically active and had successfully completed cancer treatment were randomised to an intervention or control group. PA was assessed using an ActiGraph (GT9X) at baseline, T2, and T3. Intervention effects on HRQoL were analysed using quantile regression comparing treatment groups across time. Results: A total of 87 were randomised to intervention and control groups. There were generally no statistically significant differences between the groups on any HRQoL item except for pain. There was an arm (F(1, 219) = 5.0. p = 0.027) and time (F(2,221) = 4.8, p = 0.009) effect, reflecting the higher pain scores in the control group when collapsed across time points (median difference 16.7, CI 1.9 to 31.4, p = 0.027). For global HRQoL, the intervention group increased by 8.3 points between T1 and T2. The overall group median when collapsed across time was 16.7 points CI 8.2 to 25.2, p <0.001) greater in the intervention group than controls. Conclusions: While the PPARCS intervention resulted in significant increases in PA, participants indicated a high HRQoL at baseline, leaving little room for improvement. Findings suggest that PA may improve global HRQoL and pain in breast and CRC survivors.

Food Banks as a "Treasure Trove": Users' Experiences of a Western Australian Food Relief Organization.

Food banks are providing crucial relief as food insecurity increases worldwide. While these services are essential for vulnerable populations, there is variability in foods available and users may experience poor nutritional quality, and an overabundance of discretionary foods, contributing to public health risks including overnutrition and obesity. Understanding how customers perceive food availability, variety, and quality is important to inform relief services and health interventions. This study reports the findings of a convergent parallel mixed-methods investigation of user experiences and perceptions of food availability, variety, and quality at a major food bank in Western Australia. Food bank customers (N = 207) at a food bank branch and mobile van locations completed a survey, with an option to complete a subsequent semi-structured interview (n = 15). Approximately 80% of the survey sample had low (48%) or very low (30%) food security, half of the sample had been using the food bank for longer than 6 months, and 77% reported the food bank as their first choice for food. Three-quarters (77%) reported financial barriers to a balanced diet in the past twelve months and described how limited availability and variety complicated shopping. Interviewees explained complex perceptions of these issues, including favouring healthy food while considering discretionary food as a "luxury" that enhanced their quality of life. Our findings suggest that food bank users experience barriers to maintaining a balanced diet, encounter variable supplies of healthy and nutritious foods, and have concerns about the impacts of frequent discretionary food consumption. These findings have implications for public health promotion.

Police-Identified Psychological Distress, Substance Use, and Physical Violence Among Male Intimate Partner Stalkers.

Risk factors for stalking violence are not well understood and few studies have examined psychological distress and substance use specifically. This study aimed to assess whether factors extant in police data could predict severity of stalking violence against intimate partner victims. Western Australia Police Force provided data for 603 men linked to a stalking charge relating to a female intimate partner. Binomial logistic regressions showed police-identified histories of psychological distress and drug use predicted moderate violence, but not severe violence. A co-occurring history of drug use and alcohol use was the strongest predictor of moderate violence (OR = 6.8). These findings suggest accounting for violence severity and substance type when examining stalking violence risk factors. Whether psychological distress and/or substance use were active problems for the men during their stalking behavior is unknown, however the detection of these problems may indicate an unmet need for treatment among this group.

Pharmacists' perceptions and delivery of health behaviour change recommendations: Mapping the COM-B model.

BACKGROUND: Pharmacists are trusted and accessible healthcare professionals who are well-positioned to deliver brief health behaviour change technique-based interventions for chronic health conditions. However, little is known about the factors influencing pharmacists' use of behaviour change techniques and their capacity to deliver these interventions within community pharmacy. OBJECTIVES: This study employed the COM-B model to explore the factors that explain pharmacists' delivery of behaviour change techniques in practice. A secondary objective was to ascertain whether capability, opportunity, and motivation are associated with and explain significant variance in the use of behaviour change techniques during patient interactions. METHODS: Two-hundred and eleven Australian pharmacists (mean age = 36.1, SD = 10.7) completed a survey on their capability, opportunity, and motivation to deliver behaviour change techniques, and their delivery and frequency of use in practice. RESULTS: Most pharmacists (91.3%) use behaviour change techniques during patient interactions. Results from a simple linear regression showed that a composite COM score was associated with pharmacists' behaviour change technique use F(1,195) = 47.12, ß = 0.44, 95 % CI [0.09, 0.16], p < .001, and their frequency of use (F(1,198) = 44.19, ß = 0.43, 95 % CI [0.02, 0.06], p < .001). While capability, opportunity, and motivation were individually associated with the range and frequency of behaviour change technique used, motivation was the only significant variable in the composite model for range (ß = 0.35, 95 % CI [0.11, 0.41], p < .001) and frequency of behaviour change technique use (ß = 0.22, 95 % CI [0.01, 0.09], p < .05). CONCLUSIONS: Pharmacist motivation was the most important construct explaining behaviour change technique use. Interventions should seek to foster pharmacist motivation and may benefit from adopting COM-B as a behaviour change framework, to understand the factors influencing the delivery of behaviour change interventions.

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.

Training Australian Dietitians in Behavior Change Techniques Through Educational Workshops: Protocol for a Randomized Controlled Trial.

BACKGROUND: The use of education alone as a technique to change behavior in interventions is usually insufficient, particularly in health interventions. Behavior change techniques have been shown to be effective in fostering positive changes in health behaviors such as diet and physical activity. The upskilling of health professionals can increase perceived capability and motivation toward eliciting change in clients' behaviors. However, to date, dietitians have received limited training in behavior change and have expressed a need for continuous professional development. OBJECTIVE: The study objectives are to (1) develop and evaluate the effectiveness and acceptability of two 2-hour behavior change workshops on changing dietitians behavior (ie, range of behavior change techniques used and frequency of use) across 3 time points; (2) determine if participation in these workshops will elicit changes in dietitians' perceived capability, opportunity, and motivation toward using behavior change techniques; and (3) determine the acceptability of the training and its application in practice by dietitians. METHODS: We will recruit registered dietitians (N=140) in Australia to participate in this randomized controlled trial. Participants will be randomly assigned to either the intervention or 3-month waitlist control condition and complete outcome measures at 3 time points: baseline, after the workshop, and follow-up at 3 months. Both groups will complete 2 workshops on behavior change that are guided by the COM-B (Capability, Opportunity, Motivation, and Behavior) Model and embedded with behavior change techniques. The primary outcome is changes in behavior, (ie, the range of behavior change techniques used and their frequency of use). Secondary outcomes include changes in perceived capability, opportunity, motivation, and preparedness as a health professional toward delivering behavior change techniques. The acceptability of the workshops will also be assessed after the workshop through the postworkshop survey and semistructured interviews. A series of 2-way repeated measures ANOVAs and regressions will be used. Qualitative data will be analyzed using thematic analysis. RESULTS: Participant recruitment commenced in June 2023. The results of the study are expected to be published in November 2024. The results will allow us to assess comparisons between the intervention and waitlist control groups, as well as changes in perceived capability, opportunity, motivation, and preparedness over a 3-month period. It will also provide an understanding of the acceptability of the training as a form of continuous professional development for dietitians. CONCLUSIONS: If found to be effective, the results of this 2-arm randomized controlled trial will guide future training and continuous professional development for health professionals in changing behavior in practice. Our findings will contribute to our understanding of the application of behavior change techniques in practice with clients and identify components of COM-B where dietitians may need future support.

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.

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.

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.

Wearable Activity Technology And Action-Planning (WATAAP) to promote physical activity in cancer survivors: Randomised controlled trial protocol.

Background/Objective: Colorectal and gynecologic cancer survivors are at cardiovascular risk due to comorbidities and sedentary behaviour, warranting a feasible intervention to increase physical activity. The Health Action Process Approach (HAPA) is a promising theoretical framework for health behaviour change, and wearable physical activity trackers offer a novel means of self-monitoring physical activity for cancer survivors. Method: Sixty-eight survivors of colorectal and gynecologic cancer will be randomised into 12-week intervention and control groups. Intervention group participants will receive: a Fitbit Alta™ to monitor physical activity, HAPA-based group sessions, booklet, and support phone-call. Participants in the control group will only receive the HAPA-based booklet. Physical activity (using accelerometers), blood pressure, BMI, and HAPA constructs will be assessed at baseline, 12-weeks (post-intervention) and 24-weeks (follow-up). Data analysis will use the Group x Time interaction from a General Linear Mixed Model analysis. Conclusions: Physical activity interventions that are acceptable and have robust theoretical underpinnings show promise for improving the health of cancer survivors.

Antecedentes/Objetivo: Los sobrevivientes de cáncer tienen riesgo cardiovascular debido a la comorbilidad y al comportamiento sedentario, lo que justifica desarrollar una adecuada intervención para aumentar la práctica de actividad física. El Enfoque del Proceso de Acción de Salud (EPAS) constituye un marco teórico para el desarrollo de conductas saludables y los dispositivos electrónicos de actividad física son nuevas herramientas de automonitorización para los supervivientes de cáncer. Método: Sesenta y ocho sobrevivientes de cáncer colorrectal y ginecológico serán aleatorizados en grupos de intervención y control. Los participantes del grupo de intervención recibirán un Fitbit Alta™ para monitorizar la actividad física, sesiones grupales y aplicación de un folleto de EPAS, y una llamada telefónica de apoyo. Los participantes del grupo control únicamente recibirán un folleto basado en EPAS. Al inicio del estudio, a las 12 y 24 semanas, se evaluarán la actividad física (usando acelerómetros), la presión arterial, el Índice de Masa Corporal (IMC) y los constructos EPAS. El análisis de datos utilizará la interacción Grupo x Tiempo a partir de un análisis del Modelo Mixto Lineal General. Conclusiones: Las intervenciones de actividad física son factibles y tienen fundamentos teóricos que auguran mejorar la salud de los sobrevivientes de cáncer.
