Interviews were audio-recorded, transcribed, and analyzed according to Systematic Text Condensation. The framework of Self-Determination Theory was applied to guide analysis after identification of preliminary themes.Results: Commitment and obligation were emphasized as being motivational in initiating physical activity. Toward the termination of the program, this was challenged by an expressed need for autonomy. Successful behavioral change was characterized by transfer of commitment to a new structure in everyday life, which also honored the request for autonomy. Feeling capable of participating in physical activity was facilitated through knowledge, practical experience, and progress and considered motivational, whereas lack of progress extinguished motivation. Finally, enjoyment of the activity was determining for long-term maintenance of physical activity behavior.Conclusion: Satisfaction of innate psychological needs leads to more autonomous regulation of behavior and, through this study, we investigated determining factors for extrinsically motivated behavior and factors of importance to the internalization process.

Introduction: Little is known about the optimal amount and timing of exercise strain in concern of the operation wound and with regard improvement of physical function and quality of life (QOL) after surgery for lung cancer. On this background, we decided to investigate the effect of early vs. late initiated postoperative rehabilitation in patients with operable lung cancer on exercise capacity, functional capacity, muscle strength, and QOL. Methods: The study was designed as a two-armed randomized controlled trial with randomization to either early initiated postoperative rehabilitation (14 days after surgery (ERG)) or a control arm with late initiated postoperative rehabilitation (14 weeks after surgery (LRG)). The primary endpoint was a change in maximum oxygen consumption (VO2peak) from baseline to post intervention 26 weeks following lung resection. Fatigue was measured with EORTC QLQ C30 LC13. Results: From April 2013 to June 2016, 582 patients with operable NSCLC were screened for eligibility. With 119 patients randomized in the early rehabilitation group (ERG) and 116 randomized to late rehabilitation group (LRG). There was no significant difference from baseline to 26 weeks between ERG and LRG (p = 0.926). There was a significant difference from baseline to 14 weeks between groups (p = 0.0018). There was a significant difference from 14 weeks to 26 weeks between the two groups (p < 0.001). We found no significant differences in QOL but we found a significant difference between ERG and LRG from baseline to 14 weeks in fatigue level in favour of ERG. Conclusion: This is the first randomized controlled trial to investigate the effects of early vs. late initiated postoperative rehabilitation in patients with lung cancer. There is no difference in the commencement (early vs. late) of a postoperative exercise program for patients with lung cancer on exercise capacity. But to reduce fatigue patients should be recommended to initiate early exercise programs.

Background: In HIV-infected patients on combination antiretroviral therapy (cART), lipodystrophy shares many similarities with metabolic syndrome, but only metabolic syndrome has objective classification criteria. We examined adipose tissue changes related to lipodystrophy and metabolic syndrome to clarify whether it may be acceptable to focus diagnosis on metabolic syndrome rather than lipodystrophy.Methods: A cross-sectional study of 60 HIV-infected men on cART and 15 healthy men. We evaluated lipodystrophy (clinical assessment) and metabolic syndrome (JIS-2009). We compared adipocyte size, leukocyte infiltration, and gene expression in abdominal subcutaneous adipose tissue biopsies of patients with and without lipodystrophy, and with and without metabolic syndrome.Results: Lipodystrophy was only associated with increased macrophage infiltration (P=0.04) and adiponectin mRNA (P=0.008), whereas metabolic syndrome was associated with larger adipocytes (P<0.0001), decreased expression of genes related to adipogenesis and adipocyte function (P-values between <0.0001-0.08), increased leptin mRNA (P=0.04), and a trend towards increased expression of inflammatory genes (P-values between 0.08-0.6).Conclusions: Metabolic syndrome rather than lipodystrophy was associated with major unfavourable abdominal subcutaneous adipose tissue changes. In a clinical setting, it may be more relevant to focus on metabolic syndrome diagnosis in HIV-infected patients on cART with regards to adipose tissue dysfunction and risk of cardio-metabolic complications.

Aim: To explore motivational factors for initiating, implementing, and maintaining physical activity following a rehabilitation program for patients with type 2 diabetes mellitus.Methods: Semi-structured, individual, qualitative interviews with five informants from the InterWalk trial were conducted at three separate occasions; at initiation of the rehabilitation program, at completion of the 12-week program, and 52 weeks after enrolment. Interviews were audio-recorded, transcribed, and analyzed according to Systematic Text Condensation. The framework of Self-Determination Theory was applied to guide analysis after identification of preliminary themes.Results: Commitment and obligation were emphasized as being motivational in initiating physical activity. Toward the termination of the program, this was challenged by an expressed need for autonomy. Successful behavioral change was characterized by transfer of commitment to a new structure in everyday life, which also honored the request for autonomy. Feeling capable of participating in physical activity was facilitated through knowledge, practical experience, and progress and considered motivational, whereas lack of progress extinguished motivation. Finally, enjoyment of the activity was determining for long-term maintenance of physical activity behavior.Conclusion: Satisfaction of innate psychological needs leads to more autonomous regulation of behavior and, through this study, we investigated determining factors for extrinsically motivated behavior and factors of importance to the internalization process.

OBJECTIVE: To review the evidence concerning the effects of postoperative exercise interventions on exercise capacity and health-related quality of life following resection for non-small cell lung cancer, and to review whether different initiation times of exercise produce different effects on exercise capacity.DATA SOURCES: Comprehensive literature search of MEDLINE, Embase, CENTRAL, CINAHL and PEDro.STUDY SELECTION: Randomized controlled trials examining the effects of exercise interventions were eligible for inclusion.DATA EXTRACTION: Postoperative outcome measurements were extracted and the quality of evidence was graded using Grading of Recommendations Assessment, Development and Evaluation (GRADE) Working Group.DATA SYNTHESIS: Four randomized controlled trials were identified involving 262 participants. Short-term follow-up (12-20 weeks) showed significantly higher exercise capacity and physical component of health-related quality of life in the intervention group (standardized mean difference (SMD) 0.48; 95% confidence interval (CI) 0.04-0.93) compared with the control group (SMD 0.50; 95% CI 0.19-0.82). There was no difference between the effect of late- and early-initiated exercise intervention.CONCLUSION: Exercise has a small-to-moderate effect at short-term follow-up on exercise capacity and the physical component of health-related quality of life in patients operated for lung cancer. The long-term effects of exercise capacity are unknown. Early-initiated exercise programmes (2 weeks post-operation) did not show an effect on exercise capacity. These findings should be interpreted with caution.

BACKGROUND: Knowledge about the organization and factors of importance to rehabilitation of veterans with lower limb amputation is sparse. The aim of this study was, therefore, to improve understanding of the influences of "military identity" on the organization of rehabilitation services and to investigate those factors influential in achieving successful rehabilitation, including interprofessional collaboration between different sectors involved in the rehabilitation of veterans with lower limb amputations.METHODS: We used a qualitative exploratory design, triangulating interviews and participant observation. Data were generated using in-depth semi-structured interviews (n = 6) exploring in-hospital and post-hospital rehabilitation in Danish veterans after unilateral lower limb amputation due to trauma. We conducted four sessions of participant observation, during weekly post-hospitalization rehabilitation and included field notes in the dataset.RESULTS: Two main themes emerged: "experiencing different identities" and "experiencing discontinuity in rehabilitation." The first theme illustrated how veterans actively shift between the identities of disabled person, wounded veteran and athlete according to the context. The second theme illustrated the frustration of negotiating military versus civilian mindsets during rehabilitation and lack of coordination between the public healthcare system, municipal services and the military.CONCLUSION: Veterans live with shifting identities after returning to civilian life, increasing their awareness of the transition from active service to a new life as a civilian. During rehabilitation, it is important to acknowledge the disparities between the military and civilian mindsets and to integrate the different sets of values, such as structure versus autonomy. IMPLICATIONS FOR REHABILITATION Recommendations for the improvement of rehabilitation of amputated veterans include: Rehabilitation professionals work

INTRODUCTION: Surgical resection in patients with non-small cell lung cancer (NSCLC) may be associated with significant morbidity, functional limitations, and decreased quality of life.OBJECTIVES: The objective is to present health-related quality of life (HRQoL) changes over time before and 1 year after surgery in patients with NSCLC participating in a rehabilitation program.METHODS: Forty patients with NSCLC in disease stage I to IIIa, referred for surgical resection at the Department of Cardiothoracic Surgery RT, Rigshospitalet, were included in the study. The rehabilitation program comprised supervised group exercise program, 2 hours weekly for 12 weeks, combined with individual counseling. The study endpoints were self-reported HRQoL (Functional Assessment of Cancer Therapy-Lung, European Organization for Research and Treatment in Cancer-Quality of Life Questionnaire-QLQ-C30, Short-Form-36) and self-reported distress, anxiety, depression, and social support (National Comprehensive Cancer Network Distress Thermometer, Hospital Anxiety and Depression Scale, Multidimensional Scale of Perceived Social Support), measured presurgery, postintervention, 6 months, and 1 year after surgery.RESULTS: Forty patients were included, 73% of whom completed rehabilitation. Results on emotional well-being (P < .0001), global quality of life (P = .0032), and mental health component score (P = .0004) showed an overall statistically significant improvement during the study.CONCLUSION: This feasibility study demonstrated that global quality of life, mental health, and emotional well-being improved significantly during the study, from time of diagnosis until 1 year after resection, in patients with NSCLC participating in rehabilitation.

Background: Psychological factors as depression and somatization are considered along with a high level of disability as risk factors for developing persistent low back pain (LBP). Furthermore, LBP and psychosocial distress are two of the most frequent reasons for seeking health care and sickness absence. However, it is not clear how these factors are intercorrelated. The aim of this study was to analyze how pain, fear-avoidance beliefs, depression and somatization were associated with disability in persistent LBP patients. Methods: In a cross-sectional design, 765 LBP patients filled in Roland Morris Disability Questionnaire, LBP Rating Scale, Fear-Avoidance Beliefs Questionnaire (physical activity/work) and Symptoms Checklist 90 (psychological distress). Results: In a multivariate regression analysis, disability was found to be significantly associated with pain, depression, fear-avoidance beliefs (physical activity), age and body mass index (BMI). Pain was significantly associated with disability, depression, somatization, sex and BMI. Disability, pain and the psychosocial variables were mutually correlated. Conclusion: The results of this study support earlier suggestions of an association between disability, pain and the psychosocial factors somatization, depression and fear-avoidance beliefs. The results support the importance of recognizing the mental health of LBP patients in the clinical setting.

BACKGROUND: The Patient-Reported Outcome Measurement Information System (PROMIS) is an assessment system that aims to provide more valid, reliable, responsive, and precise patient-reported outcome (PRO) measures than has been previously available. This paper documents the translation of the Physical Function item bank into Danish.METHODS: We followed the PROMIS standard procedure, including: 1) two independent translations, 2) back translation, 3) independent reviews of translation quality, and 4) cognitive interviews with a representative sample of the adult population from the municipality of Copenhagen. After each phase, the new information was reviewed and the Danish version of the PROMIS Physical Function items was revised, if warranted.RESULTS: Relatively few problems were related to translation in itself and such problems could be fixed by changes in item wordings to fit the Danish context. Cognitive testing revealed problem of a general issue: annoyance in case of mismatch between respondents' functional level and question difficulty, problems imagining performance on activities that the respondents did not usually do, and uncertainty whether mobility aids (e.g., canes and walkers) should be considered when performing an activity. Solutions to the more general issues would require revisions to the original items.CONCLUSIONS: The standard translation methodology was successful in eliminating problems in translation, and pointed to problems of a general issue in some of the original questions, producing translated Danish versions of the PROMIS Physical Functioning items. Translation and validation studies provide a valuable source when revising and improving PROs in a clinical setting or for research. The present paper exemplifies this with experiences from Denmark. The study describes how the use of PROs when measuring physical functioning in a Danish context can be improved-hence improving the items used for research, future trials an

BACKGROUND: Type 2 diabetes (T2D) is a prevalent chronic disease that affects not just patients but entire families. Both the patient and the rest of the family may benefit from gaining knowledge about the disease and from supportive interfamilial interaction. The Internet is becoming a widely-used resource for health information, so a Web-based solution could potentially promote awareness and knowledge on how to manage T2D as a family, while also providing support for the family.OBJECTIVE: We aim to assess the usage of online diabetes information by patients with T2D and their relatives, and explore the families' needs and preferences regarding online information on diabetes.METHODS: A quantitative self-reported questionnaire survey was performed with Danish families that had at least one family member diagnosed with T2D. The survey consisted of 36 closed questions on demographics, usage of the Internet, preferences in the source of information, interest in online information on six problem domains within family life related to T2D, preferences towards the delivery format of online information, and peer-to-peer communication. Two open-ended questions were also included to elicit any additional comments or suggestions about improving online information on T2D regarding family life.RESULTS: Fifty participants from 22 families with T2D answered the questionnaire individually. Relatives (25/28, 89%) and patients (22/22, 100%) indicated that information on T2D is relevant for them, while indicating that the Internet is the first or second preferred source when in need of information on T2D (25/28, 89% vs 21/22, 95%). Only a minority of the participants indicated that they had searched the Internet to gain knowledge on T2D regarding family life (9/28, 32% vs 10/22, 46%). Also, patients were more likely to have used the Internet to gain information on T2D (P=.027). Both groups indicated a preference for watching videos or reading about T2D in relat

Technology can be very valuable to support older adults to remain healthy and active in their daily living. How to design technological product and service systems that will be adopted by older adults however still remains a challenge. This paper reports on an empirical study on how a co-creation ideation process can contribute to the technology adoption of older adults conducted in an EU project with multi-stakeholder teams with the aim of promoting physical activities of older adult citizens. This ideation process is adapted from Method A. By analyzing the co-creation ideation process from three different processes: the end user value-creation process, the stakeholder value-creation process and the encounter process in relation to the technology adoption process, i.e., the domestication adoption process, this paper demonstrates which technology adoption issues can be already addressed using this cocreation ideation process and which aspects still need to be taken further into account.

Importance: It is unclear whether a lifestyle intervention can maintain glycemic control in patients with type 2 diabetes.Objective: To test whether an intensive lifestyle intervention results in equivalent glycemic control compared with standard care and, secondarily, leads to a reduction in glucose-lowering medication in participants with type 2 diabetes.Design, Setting, and Participants: Randomized, assessor-blinded, single-center study within Region Zealand and the Capital Region of Denmark (April 2015-August 2016). Ninety-eight adult participants with non-insulin-dependent type 2 diabetes who were diagnosed for less than 10 years were included. Participants were randomly assigned (2:1; stratified by sex) to the lifestyle group (n = 64) or the standard care group (n = 34).Interventions: All participants received standard care with individual counseling and standardized, blinded, target-driven medical therapy. Additionally, the lifestyle intervention included 5 to 6 weekly aerobic training sessions (duration 30-60 minutes), of which 2 to 3 sessions were combined with resistance training. The lifestyle participants received dietary plans aiming for a body mass index of 25 or less. Participants were followed up for 12 months.Main Outcomes and Measures: Primary outcome was change in hemoglobin A1c (HbA1c) from baseline to 12-month follow-up, and equivalence was prespecified by a CI margin of ±0.4% based on the intention-to-treat population. Superiority analysis was performed on the secondary outcome reductions in glucose-lowering medication.Results: Among 98 randomized participants (mean age, 54.6 years [SD, 8.9]; women, 47 [48%]; mean baseline HbA1c, 6.7%), 93 participants completed the trial. From baseline to 12-month follow-up, the mean HbA1c level changed from 6.65% to 6.34% in the lifestyle group and from 6.74% to 6.66% in the standard care group (mean between-group difference in change of -0.26% [95% CI, -0.52% to -0.01%])

INTRODUCTION: Physical activity is a cornerstone in type 2 diabetes (T2D) rehabilitation. Effective long-term and low-cost strategies to keep these patients' physically active are needed. However, maintaining physical activity behaviour is difficult once formalised interventions end. Structured exercise training supported by mobile technology and remote feedback is potentially an effective strategy. The objective of the trial is to investigate whether mobile health support using the InterWalk application for smartphones is effective in increasing physical activity levels in persons with T2D over time compared with standard care. We investigate whether Interval Walking Training using the InterWalk application is superior to Danish municipality-based rehabilitation in increasing moderate-and-vigorous physical activity levels in patients with T2D across 52 weeks. Secondary, we hypothesise that a motivational programme added from end of intervention to 52 weeks further increases level of physical activity in everyday life in patients with T2D.METHODS AND ANALYSIS: The trial is a parallel-group, open-labelled, randomised controlled trial with long-term follow-up at 52 week including patients with T2D. The primary outcome is change in moderate-and-vigorous physical activity. The key secondary outcome includes motivation for physical activity behaviour change. Other secondary outcomes are VO2-peak, strength in the lower extremities. Exclusion criterion is medical contraindication to exercise. We include up to 246 patients and randomly allocate them into a control (standard group) or an experimental group (8-12 weeks of IWT supported by the smartphone-based InterWalk application) in a 1:2 fashion. After intervention, the experimental group is randomly allocated into two follow-up conditions with unsupervised IWT with or without motivational support until 52-week follow-up. The intention-to-treat principle is applied.ETHICS AND DISSEMINATION: The local regio

Background: Most amputees live with their prostheses for a long time. Therefore, quality of life is an important outcome for lower limb amputees. Objective: To translate the Prosthesis Evaluation Questionnaire (PEQ) and evaluate psychometric properties. Study Design: Methodological research. Methods: Lower limb amputees responded to electronic versions of the PEQ and SF-36v2 at baseline (n=64), after two weeks (n=51), and after 12 weeks (n=50). Reliability was assessed using Cronbach’s alpha and intraclass correlation coefficient (ICC) analyses of the baseline and two weeks test-retest data. Estimates for standard error of measurement (SEM) were calculated based on reliability estimates. Construct validity was evaluated by testing using hypotheses testing. Results: Reliability estimates (ICC/Cronbach’s alpha) for the nine subscales were: Social Burden (0.85/0.76), Appearance (0.85/0.72), Residual Limb Health (0.80/0.69), Well-Being (0.78/0.90), Utility (0.76/0.89), Frustration (0.74/0.90), Perceived Response (0.62/0.80), Ambulation (0.61/0.94), Sounds (0.51/0.65). Construct validity was supported in three out of four subscales evaluated. Conclusions: The subscales Social Burden, Appearance, Well-Being, Utility and Frustration had consistent high reliability, supporting their use in assessing the prosthesis related quality of life in lower limb amputees. Results were mixed on three other scales (Residual Limb Health, Perceived Response, and Ambulation), while one scale, Sounds, had consistent low reliability. Clinical relevance: For the first time a patient reported disease specific quality of life measure for lower limb amputees is available in Danish. Health care providers can now identify patients with reduced quality of life and measure treatment and rehabilitation effects over time.

BACKGROUND: Digital interventions for improving diabetes management in Type 2 diabetes mellitus (T2DM) are used universally. Digital interventions are defined as any intervention accessed and taking input from people with T2DM in the form of a web-based or mobile phone-based app to improve diabetes self-management. However, the current confidence in digital interventions threatens to augment social inequalities in health, also known as the "digital divide". To counteract dissemination of the digital divide, we aimed to assess the potential of a tailored digital intervention for improving diabetes management in vulnerable people with T2DM.METHODS: A qualitative design using semi-structured in-depth interviews to explore the perspectives of 12 vulnerable people with T2DM. Interviews were analyzed using inductive content analysis. Vulnerability was defined by the presence of one or more comorbidities, one or more lifestyle risk factors, poor diabetes management, low educational level and low health literacy.RESULTS: The main themes identified were: "Dealing with diabetes distress" characterized by psychological avoidance mechanisms; "Suffering informational confusion" dealing with inconsistent information; "Experiencing digital alienation" dealing with loss of freedom when technology invades the private sphere; and "Missing the human touch" preferring human interaction over digital contact.CONCLUSION: Vulnerable people with T2DM are unprepared for digital interventions for disease management. Experiencing diabetes distress may be an intermediate mechanism leading to nonadherence to digital interventions and the preference for human interaction in vulnerable people with T2DM. Future interventions could include a designated caregiver and an allocated buddy to provide support and assist uptake of digital interventions for diabetes management.

In order to examine the association between pre-pregnancy leisure time physical activities and gestational weight gain, postpartum weight gain and birth weight, we analysed prospectively collected data from 1827 women with singleton term pregnancies. Women were categorised in groups of sedentary women, light exercisers, moderate exercisers and competitive athletes. The results showed that sedentary women on average gained 14.1 kg during pregnancy, whereas light exercisers gained 13.7 kg, moderate exercisers gained 14.3 kg and competitive athletes 16.1 kg. Competitive athletes had an increased risk of having a gestational weight gain above Institute of Medicine (IOM) recommendations with an odds ratio of 2.60 (1.32-5.15) compared to light exercisers. However, birth weight and one year postpartum weight was similar for all four groups. Thus, although competitive athletes gain more weight than recommended during pregnancy, this may not affect birth weight or postpartum weight. Impact statement: What is already known on this subject: Previous studies have found that increased pre-pregnancy physical activity is associated with lower gestational weight gain during the last trimester, but showed no association between the pre-pregnancy level of physical activity and mean birth weight. What the results of this study add: We found that women classified as competitive exercisers had a 2.6-fold increased risk of gaining more weight than recommended compared to light exercisers. Nearly 6 out of 10 women among the competitive exercisers gained more weight than recommended by IOM. Surprisingly, this did not appear to increase birth weight or post-partum weight gain, but other adverse effects cannot be excluded. What the implications are of these findings for clinical practice and/or further research: In the clinical practice it may be relevant to focus on and advise pre-pregnancy competitive exercisers in order to prevent excessive gestational weight gain.

BACKGROUND: Injection therapies are often considered alongside exercise for chronic midportion Achilles tendinopathy (AT), although evidence of their efficacy is sparse.PURPOSE: To determine whether eccentric training in combination with high-volume injection (HVI) or platelet-rich plasma (PRP) injections improves outcomes in AT.STUDY DESIGN: Randomized controlled trial; Level of evidence, 1.METHODS: A total of 60 men (age, 18-59 years) with chronic (>3 months) AT were included and followed for 6 months (n = 57). All participants performed eccentric training combined with either (1) one HVI (steroid, saline, and local anesthetic), (2) four PRP injections each 14 days apart, or (3) placebo (a few drops of saline under the skin). Randomization was stratified for age, function, and symptom severity (Victorian Institute of Sports Assessment-Achilles [VISA-A]). Outcomes included function and symptoms (VISA-A), self-reported tendon pain during activity (visual analog pain scale [VAS]), tendon thickness and intratendinous vascularity (ultrasonographic imaging and Doppler signal), and muscle function (heel-rise test). Outcomes were assessed at baseline and at 6, 12, and 24 weeks of follow-up.RESULTS: VISA-A scores improved in all groups at all time points ( P < .05), with greater improvement in the HVI group (mean ± SEM, 6 weeks = 27 ± 3 points; 12 weeks = 29 ± 4 points) versus PRP (6 weeks = 14 ± 4; 12 weeks = 15 ± 3) and placebo (6 weeks = 10 ± 3; 12 weeks = 11 ± 3) at 6 and 12 weeks ( P < .01) and in the HVI (22 ± 5) and PRP (20 ± 5) groups versus placebo (9 ± 3) at 24 weeks ( P < .01). VAS scores improved in all groups at all time points ( P < .05), with greater decrease in HVI (6 weeks = 49 ± 4 mm; 12 weeks = 45 ± 6 mm; 24 weeks = 34 ± 6 mm) and PRP (6 weeks = 37 ± 7 mm; 12 weeks = 41 ± 7 mm; 24 weeks = 37 ± 6 mm) versus placebo (6 weeks = 23 ± 6 mm; 12 weeks = 30 ± 5 mm; 24 weeks = 18 ± 6 mm) at all time points ( P < .0

Objectives: Sustainment of healthy exercise behavior is essential in preventing cardiovascular disease and diabetes. Few studies have explored long-term exercise adherence after an exercise referral scheme. The objective of this study was to examine 12-month exercise adherence after an exercise intervention program. Methods: This was a pragmatic follow-up study in at-risk people performed between June 2012 and January 2014. The main outcome measure was self-reported single-item exercise adherence. Secondary outcomes were change in exercise level, quality of life rated on a visual analog scale and self-rated health. Predictors of long-term exercise adherence were assessed by logistic regression, estimating crude odds-ratios (OR) and 95% confidence intervals (95% CIs) and adjusting for age, gender, education, smoking, moderate and vigorous exercise. Results: In total, 214 adults (mean age 58.8. ±. 11.97 years, 71% women) participated in the study and received a 12-week training intervention: 62% had hypertension, 64% dyslipidemia and 15% impaired glucose tolerance. Attrition rate was 84% (n = 179). During the 12-month follow-up, 48% (n = 85) reported long-term exercise adherence. The main predictors of long-term exercise adherence were participation in sport activities at baseline (adjusted odds-ratio [aOR] 4.22, 95% CI 1.72-10.40), self-rated health (aOR 2.60, 1.00-6.75) and quality of life (aOR 2.39, 1.03-5.54). Long-term non-adherence was associated with low education (<. 10 years; aOR 3.27, 1.14-9.43) and age. <. 50 years (aOR 3.53, 1.32-9.43). Conclusions: In this pragmatic study, long-term exercise adherence was associated with participation in sport activities and self-rated health at baseline.

OBJECTIVES: The aim of this study was to investigate if exercise intensity guided by rating of perceived exertion (RPE) results in an equivalent cardiovascular response when applied in either a center-based or a home-based setting.DESIGN: Data from patients with heart disease (post-valve surgery and atrial fibrillation post-radiofrequency ablation) participating in exercise-based rehabilitation were included. Patients performed a 12-week program in either a center- or a home-based setting. Using RPE, patients recorded their exercise intensity 3 times during an aerobic training phase. Exercise intensity was objectively measured using heart rate (HR) monitors.RESULTS: A total of 2622 RPE values with corresponding HR data were available. There was no difference in the level of association (interaction P = 0.51) between HR and RPE seen in the center-based setting (mean of 6.1 beats/min per 1.0 difference in RPE; 95% confidence interval, 4.8-7.5 beats/min) compared with the home-based setting (mean of 5.3 beats/min per 1.0 difference in RPE; 95% confidence interval, 4.0-6.5 beats/min). The level of patient familiarization, exercise intensity, and patient characteristics did not affect the level of association between RPE and HR.CONCLUSIONS: Independent of exercise setting, RPE appears to be equally effective in guiding exercise intensity of patients participating in cardiac rehabilitation.
