[Ab] Resumo:BACKGROUND: Unhealthy lifestyles are a major factor in the development and exacerbation of many chronic diseases. Improving lifestyles though immersive residential experiences that promote healthy behaviours is a focus of the health retreat industry. This systematic review aims to identify and explore published studies on the health, wellbeing and economic impact of retreat experiences. METHODS: MEDLINE, CINAHL and PsychINFO databases were searched for residential retreat studies in English published prior to February 2017. Studies were included if they were written in English, involved an intervention program in a residential setting of one or more nights, and included before-and-after data related to the health of participants. Studies that did not meet the above criteria or contained only descriptive data from interviews or case studies were excluded. RESULTS: A total of 23 studies including eight randomised controlled trials, six non-randomised controlled trials and nine longitudinal cohort studies met the inclusion criteria. These studies included a total of 2592 participants from diverse geographical and demographic populations and a great heterogeneity of outcome measures, with seven studies examining objective outcomes such as blood pressure or biological makers of disease, and 16 studies examining subjective outcomes that mostly involved self-reported questionnaires on psychological and spiritual measures. All studies reported post-retreat health benefits ranging from immediately after to five-years post-retreat. Study populations varied widely and most studies had small sample sizes, poorly described methodology and little follow-up data, and no studies reported on health economic outcomes or adverse effects, making it difficult to make definite conclusions about specific conditions, safety or return on investment. CONCLUSIONS: Health retreat experiences appear to have health benefits that include benefits for people with chronic diseases such as multiple sclerosis, various cancers, HIV/AIDS, heart conditions and mental health. Future research with larger numbers of subjects and longer follow-up periods are needed to investigate the health impact of different retreat experiences and the clinical populations most likely to benefit. Further studies are also needed to determine the economic benefits of retreat experiences for individuals, as well as for businesses, health insurers and policy makers.

[Ti] Título:Unwanted effects: Is there a negative side of meditation? A multicentre survey.

[Ab] Resumo:OBJECTIVES: Despite the long-term use and evidence-based efficacy of meditation and mindfulness-based interventions, there is still a lack of data about the possible unwanted effects (UEs) of these practices. The aim of this study was to evaluate the occurrence of UEs among meditation practitioners, considering moderating factors such as the type, frequency, and lifetime duration of the meditation practices. METHODS: An online survey was developed and disseminated through several websites, such as Spanish-, English- and Portuguese-language scientific research portals related to mindfulness and meditation. After excluding people who did not answer the survey correctly or completely and those who had less than two months of meditation experience, a total of 342 people participated in the study. However, only 87 reported information about UEs. RESULTS: The majority of the practitioners were women from Spain who were married and had a University education level. Practices were more frequently informal, performed on a daily basis, and followed by focused attention (FA). Among the participants, 25.4% reported UEs, showing that severity varies considerably. The information requested indicated that most of the UEs were transitory and did not lead to discontinuing meditation practice or the need for medical assistance. They were more frequently reported in relation to individual practice, during focused attention meditation, and when practising for more than 20 minutes and alone. The practice of body awareness was associated with UEs to a lesser extent, whereas focused attention was associated more with UEs. CONCLUSIONS: This is the first large-scale, multi-cultural study on the UEs of meditation. Despite its limitations, this study suggests that UEs are prevalent and transitory and should be further studied. We recommend the use of standardized questionnaires to assess the UEs of meditation practices.

[Ab] Resumo:BACKGROUND: Colorectal cancer imposes threats to patients' well-being. Although most physical symptoms can be managed by medication, psychosocial stressors may complicate survival and hamper quality of life. Mindfulness and Qigong, two kinds of mind-body exercise rooted in Eastern health philosophy, has been found effective in symptoms management, improving mental health, and reducing stress. With these potential benefits, a randomized controlled trial (RCT) is planned to investigate the comparative effectiveness of mindfulness and Baduanjin intervention on the bio-psychosocial wellbeing of people with colorectal cancer. METHODS/ DESIGN: A 3-arm RCT with waitlist control design will be used in this study. One hundred eighty-nine participants will be randomized into (i) Mindfulness, (ii) Baduanjin, or (iii) waitlist control groups. Participants in both the Baduanjin and mindfulness groups will receive 8-weeks of specific intervention. All three groups will undergo four assessment phases: (i) at baseline, (ii) at 4-week, (iii) at 8-week (post-intervention), and 6-month post-intervention (maintenance). All participants will be assessed in terms of cancer-related symptoms and symptom distress, mental health status, quality of life, stress level based on physiological marker. DISCUSSION: Based on prior research studies, participants in both the mindfulness and Baduanjn intervention group are expected to have better symptoms management, lower stress level, better mental health, and higher level of quality of life than the control group. This study contributes to better understanding on the common and unique effectiveness of mindfulness and Baduanjin qigong, as such patients and qualified healthcare professionals can select or provide practices which will produce maximum benefits, satisfaction, adherence, and sustainability. TRIAL REGISTRATION: The trial has been registered in the Clinical Trials Centre of the University of Hong Kong ( HKCTR-2198 ) on 08 March 2017.

[Ti] Título:Prevalence and patterns of use of mantra, mindfulness and spiritual meditation among adults in the United States.

[Ab] Resumo:BACKGROUND: Despite a growing body of scientific literature exploring the nature of meditation there is limited information on the characteristics of individuals who use it. This is particularly true of comparative studies examining prevalence and predictors of use of various forms of meditation. METHODS: A secondary analysis was conducted using data from the 2012 National Health Interview Survey (n = 34,525). Three popular forms of meditation were compared-mantra, mindfulness, and spiritual-to determine lifetime and 12-month use related to key sociodemographic, health behavior, health status, and healthcare access variables. RESULTS: The 12-month prevalence for meditation practice was 3.1% for spiritual meditation, 1.9% for mindfulness meditation, and 1.6% for mantra meditation. This represents approximately 7.0, 4.3, and 3.6 million adults respectively. A comparison across the three meditation practices found many similarities in user characteristics, suggesting interest in meditation may be more related to the type of person meditating than to the type of practice selected. Across meditation styles use was more prevalent among respondents who were female, non-Hispanic White, college educated, physically active; who used other complementary health practices; and who reported depression. Higher utilization of conventional healthcare services was one of the strongest predictors of use of all three styles. In addition to similarities, important distinctions were observed. For example, spiritual meditation practice was more prevalent among former drinkers. This may reflect use of spiritual meditation practices in support of alcohol treatment and sobriety. Reasons for use of meditation were examined using the sample of respondents who practiced mindfulness meditation. Wellness and prevention (74%) was a more common reason than use to treat a specific health condition (30%). Common reasons for use included stress management (92%) and emotional well-being (91%), and to support other health behaviors. Meditation was viewed positively because it was self-care oriented (81%) and focused on the whole person (79%). CONCLUSION: Meditation appears to provide an accessible, self-care resource that has potential value for mental health, behavioral self-regulation, and integrative medical care. Considering consumer preference for distinct types of meditation practices, understanding the underlying mechanisms, benefits, and applications of practice variations is important.

[Ti] Título:The varieties of contemplative experience: A mixed-methods study of meditation-related challenges in Western Buddhists.

[Ab] Resumo:Buddhist-derived meditation practices are currently being employed as a popular form of health promotion. While meditation programs draw inspiration from Buddhist textual sources for the benefits of meditation, these sources also acknowledge a wide range of other effects beyond health-related outcomes. The Varieties of Contemplative Experience study investigates meditation-related experiences that are typically underreported, particularly experiences that are described as challenging, difficult, distressing, functionally impairing, and/or requiring additional support. A mixed-methods approach featured qualitative interviews with Western Buddhist meditation practitioners and experts in Theravada, Zen, and Tibetan traditions. Interview questions probed meditation experiences and influencing factors, including interpretations and management strategies. A follow-up survey provided quantitative assessments of causality, impairment and other demographic and practice-related variables. The content-driven thematic analysis of interviews yielded a taxonomy of 59 meditation-related experiences across 7 domains: cognitive, perceptual, affective, somatic, conative, sense of self, and social. Even in cases where the phenomenology was similar across participants, interpretations of and responses to the experiences differed considerably. The associated valence ranged from very positive to very negative, and the associated level of distress and functional impairment ranged from minimal and transient to severe and enduring. In order to determine what factors may influence the valence, impact, and response to any given experience, the study also identified 26 categories of influencing factors across 4 domains: practitioner-level factors, practice-level factors, relationships, and health behaviors. By identifying a broader range of experiences associated with meditation, along with the factors that contribute to the presence and management of experiences reported as challenging, difficult, distressing or functionally impairing, this study aims to increase our understanding of the effects of contemplative practices and to provide resources for mediators, clinicians, meditation researchers, and meditation teachers.

[Ab] Resumo:OBJECTIVES: As rates of opiate misuse rise in the United States, so do significant associated health and financial consequences to afflicted individuals, their families, and society at large. Methadone maintenance therapy (MMT) is one evidence-based approach to treating opiate addiction, yet supplemental psychosocial treatment to support this approach is lacking. Mindfulness-based relapse prevention (MBRP) has shown to be efficacious in various substance use populations, but has yet to be assessed with MMT clients. DESIGN: The current mixed methods study was designed to inform protocol adaptation for MMT clients and to evaluate the feasibility, acceptability, and preliminary efficacy of MBRP for this population. SUBJECTS: The sample consisted of adults (N = 15) recruited from a methadone clinic to participate in a 6-week MBRP course. OUTCOME MEASURES: Data from focus groups and course satisfaction surveys supported feasibility and acceptability of the intervention. Self-report outcome measures included depression, anxiety, craving, symptoms of post-traumatic stress, and experiential avoidance, and were assessed at baseline and postcourse. RESULTS: Mean scores on all primary outcomes changed in the expected direction at postcourse, and baseline to postcourse changes in depression, craving, and trauma symptoms reached statistical significance. CONCLUSIONS: Results from this initial pilot trial support feasibility and acceptability, and provide preliminary data on outcomes for future trials of mindfulness-based approaches within the MMT community.

[Ti] Título:The Effects of Yoga on Positive Mental Health Among Healthy Adults: A Systematic Review and Meta-Analysis.

[Ab] Resumo:OBJECTIVES: The aim of this study was to present an overview of the research on the effects of yoga on positive mental health (PMH) among non-clinical adult populations. METHODS: This was a systematic literature review and meta-analysis, including a risk of bias assessment. The electronic databases PubMed/Medline, Scopus, IndMED, and the Cochrane Library were searched from 1975 to 2015. Randomized controlled trials (RCTs) on the effects of yoga interventions on PMH among a healthy adult population were selected. RESULTS: A total of 17 RCTs were included in the meta-analysis. Four indicators of PMH were found: psychological well-being, life satisfaction, social relationships, and mindfulness. A significant increase in psychological well-being in favor of yoga over no active control was found. Overall risk of bias was unclear due to incomplete reporting. CONCLUSIONS: The current body of research offers weak evidence that the practice of yoga contributes to an increase in PMH among adults from non-clinical populations in general. Yoga was found to contribute to a significant increase in psychological well-being when compared to no intervention but not compared to physical activity. For life satisfaction (emotional well-being), social relationships (social well-being), and mindfulness no significant effects for yoga were found over active or non-active controls. Due to the limited amount of studies, the heterogeneity of the intervention, and perhaps the way PMH is being measured, any definite conclusions on the effects of yoga on PMH cannot be drawn.

[Ab] Resumo:OBJECTIVES: Radiation treatment for head and neck cancer introduces adaptive demands and subjects patients to significant and unique psychosocial challenges. There is growing evidence that meditation is useful in lessening anxiety and depression in cancer patients. This study compared the effects of two types of meditation training on the psychological responses of patients with head and neck cancer during radiation therapy. DESIGN: Randomized clinical trial. SETTING: Smilow Cancer Hospital at Yale New Haven. PATIENTS: A total of 29 patients with head and neck cancers were recruited and 28 patients were followed during their radiation therapy over 12 weeks. INTERVENTIONS: Depending on their group assignment, patients were taught one of two standardized meditations: meditation with a coach or self-meditation with a CD. OUTCOME MEASURES: Patient psychosocial responses were defined as anxiety, depression, and emotional distress and were measured by the Hospital and Anxiety Depression Scale (HADS) and the Emotional Distress Thermometer. Measures were self-reported and collected by the nurse manager at baseline and 6 and 12 weeks during the patient's scheduled weekly visit. RESULTS: No significant mean differences were found between the two meditation groups on all three outcomes: anxiety, depression, and emotional distress. Patients in both the meditation with a coach and self-meditation with a CD groups reported less distress from baseline and at 6 and 12 weeks, as evidenced by the HADS anxiety scale. CONCLUSIONS: This study demonstrated two equally effective meditation techniques that can be implemented with patients experiencing high stress during radiation treatments in any health care setting to decrease patient anxiety, depression, and emotional distress. The data established self-meditation with a CD as a more cost-effective alternative to meditation with a coach, which requires intensive training and time commitment for patients.

[Ab] Resumo:BACKGROUND: Chronic activation of the stress-response can contribute to cardiovascular disease risk, particularly in sedentary individuals. This study investigated the effect of a Bikram yoga intervention on the high frequency power component of heart rate variability (HRV) and associated cardiovascular disease (CVD) risk factors (i.e. additional domains of HRV, hemodynamic, hematologic, anthropometric and body composition outcome measures) in stressed and sedentary adults. METHODS: Eligible adults were randomized to an experimental group (n = 29) or a no treatment control group (n = 34). Experimental group participants were instructed to attend three to five supervised Bikram yoga classes per week for 16 weeks at local studios. Outcome measures were assessed at baseline (week 0) and completion (week 17). RESULTS: Sixty-three adults (37.2 ± 10.8 years, 79% women) were included in the intention-to-treat analysis. The experimental group attended 27 ± 18 classes. Analyses of covariance revealed no significant change in the high-frequency component of HRV (p = 0.912, partial η  = 0.000) or in any secondary outcome measure between groups over time. However, regression analyses revealed that higher attendance in the experimental group was associated with significant reductions in diastolic blood pressure (p = 0.039; partial η  = 0.154), body fat percentage (p = 0.001, partial η  = 0.379), fat mass (p = 0.003, partial η  = 0.294) and body mass index (p = 0.05, partial η  = 0.139). CONCLUSIONS: A 16-week Bikram yoga program did not increase the high frequency power component of HRV or any other CVD risk factors investigated. As revealed by post hoc analyses, low adherence likely contributed to the null effects. Future studies are required to address barriers to adherence to better elucidate the dose-response effects of Bikram yoga practice as a medium to lower stress-related CVD risk. TRIAL REGISTRATION: Retrospectively registered with Australia New Zealand Clinical Trials Registry ACTRN12616000867493 . Registered 04 July 2016.
