Hatha yoga for depression: critical review of the evidence for efficacy, plausible mechanisms of action, and directions for future research

Indirect Interventions: Lifestyle Options to Treat Mental Disorders

Mental disorders are highly prevalent worldwide. Unfortunately, most people with these disorders do not receive any treatment. This is due in part to a large set of barriers (e.g., no access to therapists or clinics, lack of insurance, stigma) that impede seeking and obtaining mental health services. Many lifestyle interventions that are not part of traditional mental health services have indirect effects on reducing symptoms of mental disorders. These are interventions that target a direct focus (e.g., physical health, socialization, general well-being) but also have indirect and significant impact on reducing mental disorders. This article discusses indirect interventions as an additional way of reaching people in need of help with mental health problems. Interventions such as physical activity and exercise, diet, addressing sleep problems, yoga, tai chi, qigong, and volunteering have indirect beneficial effects. This article highlights the scope of mental illness as a background, introduces indirect interventions, and details three illustrations with evidence that targeting one focus with indirect effects on improving mental disorders. The interventions point to a category of interventions are not systematically used in the care of mental health problems. Among their many advantages is the prospect of their use at the levels of individuals and populations. Indirect interventions do not replace any of the current advances in treatment but add to ways of reaching people in need.

A META analysis and systematic review of the effects of exercise interventions on middle-aged and elderly patients with depression

OBJECTIVE

This study sought to conduct a meticulous systematic review, delving into the efficacy of exercise interventions on depressive symptoms among middle-aged and older adults. Additionally, we aimed to scrutinize the nuanced influence of various intervention factors on the intricate relationship between exercise and depressive symptoms within this demographic.

METHODS

Our investigation involved an extensive search across multiple databases, including PubMed, Embase, Web of Science, and the Cochrane Library, spanning from the inception of these repositories to December 2023. Following a rigorous screening process, we identified and included 12 papers, encompassing a total of 994 subjects.

RESULTS

The meta-analysis unveiled a compelling overall effect size of exercise interventions on depressive symptoms in middle-aged and older individuals, represented by SMD = -0.41, with a 95% confidence interval of [-0.60, -0.22], and P < 0.0001. This statistical evidence underscores the significant and positive impact of exercise interventions on ameliorating depressive symptoms in this demographic. However, a degree of heterogeneity among studies was observed, with I2 = 48% and P = 0.03.

CONCLUSION

The comprehensive synthesis of outcomes elucidates the pronounced positive effect of exercise interventions in enhancing depressive symptoms among middle-aged and older adults. Specifically, the gentle and balanced exercise series emerges as particularly efficacious in mitigating depression. Furthermore, individual exercises stand out as more effective, with optimal results noted for moderate exercise sessions lasting 30 to 60 minutes. Our findings also highlight the superiority of short-term interventions, followed by medium- and long-term exercise interventions, in terms of efficacy. Nevertheless, recognizing the inherent heterogeneity and potential limitations of our study, we advocate for future large-scale, comprehensive investigations to validate these findings. Additionally, optimizing exercise intervention protocols necessitates a more nuanced understanding, urging further research endeavors to refine strategies aimed at improving depressive symptoms in middle-aged and older adults.

Yoga as an adjunct treatment for eating disorders: a qualitative enquiry of client perspectives

BACKGROUND

This qualitative enquiry explores the experiences and perspectives of individuals with an eating disorder (ED) regarding their perceptions of yoga as an adjunct intervention to psychotherapy. It also explores the feasibility, acceptability, and safety of yoga from their perspectives.

METHODS

This study used a practice-based evidence framework and employed semi-structured interviews with 16 females with an ED. Participants were asked about their perspectives on the use of yoga as an adjunct intervention in ED recovery, perceived risks and what factors supported or hindered engagement. Thematic template analysis was used.

RESULTS

Three topic areas were elaborated. The first included participants' perceptions of how yoga enhanced their ED recovery. The second included how and when participants came to find yoga in their ED recovery. The final topic explored factors that supported participants with ED to engage in yoga. These resulted in the development of guiding principles to consider when designing a yoga intervention for EDs.

CONCLUSIONS

This study adds further to the emerging evidence that yoga can bring complementary benefits to ED recovery and provides a biopsychosocial-spiritual framework for understanding these. Findings provide an understanding of how yoga programs can be adapted to improve safety and engagement for people with an ED. Yoga programs for people with EDs should be co-designed to ensure that the physical, social, and cultural environment is accessible and acceptable.

Holistic frailty prevention: The promise of movement-based mind-body therapies

Aging is characterized by fundamental cellular and molecular hallmarks that result in physiologic decline of most body systems. This may culminate in frailty, a state of decreased reserve. Because frailty is a state of multisystem dysregulation, multimodal interventions may be necessary to mitigate and prevent progression rather than interventions targeting a single system. Movement-based mind-body therapies, such as tai chi and yoga, are promising multimodal strategies for frailty prevention and treatment given their inherent multicomponent nature. In this review, we summarize the links between hallmarks of aging and frailty and how tai chi and yoga may impact these hallmarks. We review trial evidence for the impact of tai chi and yoga on frailty in older populations and discuss opportunities for future research.

Yoga as an adjunct treatment for the eating disorders: A qualitive enquiry of clinician perspectives

BACKGROUND

Yoga has been recognised as a beneficial adjunct for eating disorder (ED) treatment due to demonstrating positive effects on ED symptomology. Despite this, research exploring the perspectives of clinicians regarding the use of yoga for the spectrum of the EDs is limited. Consequently, this study utilised qualitative enquiry to explore the experiences and perspectives of clinicians regarding the implementation of yoga as an adjunct for ED treatment. This research examines how yoga may be safely applied for the EDs, to enhance ED treatment approaches and recovery.

METHODS

This study employed semi-structured interviews with 12-clincians with up to 20-years of experience working therapeutically with people with EDs. Participants were asked their perspectives on the benefits, risks, and adaptations for delivering safe and suitable yoga programs for the spectrum of EDs. Template thematic analysis was used.

RESULTS

Four distinct themes were identified. They included the (1) benefits of yoga, (2) risks associated with the practice, (3) recommendations for adapting yoga for this cohort, and (4) implementing yoga alongside current psychological treatment.

CONCLUSIONS

Clinicians viewed yoga as a safe and suitable transdiagnostic treatment, with the potential to support individuals with a more holistic and sustained recovery model. Clinicians raised concerns that might arise with the use of yoga for this cohort, however, they also emphasised the ability for these to be mitigated with a series of key adaptations. Importantly, clinicians recommended that yoga is implemented and monitored alongside ED treatment to ensure its suitability and safety. Key barriers for implementing yoga as an adjunct treatment and future research directions are discussed. Recent research has explored the benefits of yoga for individuals with eating disorders (EDs). However, researchers have not yet interviewed clinicians who work with those with EDs regarding their views on using yoga for their clients. This study therefore interviewed 12 clinicians working with individuals with EDs, to obtain their views for using yoga as a therapeutic treatment for this group. Overall, clinicians viewed yoga as a safe and beneficial treatment for EDs. While some concerns were raised regarding the safety of yoga for this group, clinicians emphasised that these could be relieved by a series of key adaptations. This study offers unique insights into how yoga may be safely applied into the care for ED clients, to enhance their treatment approaches and recovery.

Do yoga and meditation moderate the relationship between negative life events and depressive symptoms? Analysis of a national cross-sectional survey of Australian women

Objectives

This study aims to examine the role of yoga/meditation in the relationship between negative life events, stress and depression.

Methods

The Australian Longitudinal Study on Women's Health (ALSWH) surveyed 7,186 women aged 36-43 years (mean age 39.2 years; 57.2% university degree) in 2015. Mediation and moderation analyses were conducted to examine whether yoga/meditation practice moderated those relationships.

Results

Yoga/meditation was practiced by 27.5% of participants, 33.2% reported negative life events in the past 12 months, and 24% had clinical depression. Perceived stress partially mediated the association between negative life events and depressive symptoms (B = 6.28; 95%CI 5.65; 6.92). Social support (B = -0.38; 95%CI -0.54; -0.23) and optimism (B = -0.25;95%CI -0.31; -0.18) moderated the association between stress and depressive symptoms. Yoga/meditation practice moderated the direct association between negative life events and depressive symptoms (B = -0.92; 95%CI -1.67; -0.18).

Conclusion

Yoga/meditation use was a significant moderator of the relationship between negative life events and depression. Yoga/mediation use did not act via reducing perceived stress, but instead was found to dampen the influence of negative life events on depression directly. More research on how yoga has an impact on depression is warranted.

Role of yoga in stress management and implications in major depression disorder

Major Depressive Disorder (MDD) is one of the leading causes of disability affecting more than 340 million people and second largest contributor to global burden of disease. Chronic stress is a common risk factor and important contributor for MDD. Stress could be defined as the "perceived inability to cope". Stressful life events are shown to provoke a sequence of psychological and physiological adjustments including nervous, endocrine and immune mechanisms. Stress can lead to elevation of a variety of inflammatory cytokines and stress hormones, can cause autonomic dysfunction and imbalance in neurotransmitters. Yoga can reduce depressive symptoms by alleviating stress. Studies have shown that yoga can reduce inflammation, maintain autonomic balance and also has a role in maintaining the neurotransmitters. It has role on hypothalamic-pituitary-adrenal (HPA) axis, the peripheral nervous system including GABA, limbic system activity, inflammatory and endocrine responses. Yoga along with antidepressants can help in reducing the depressive symptoms in patient with MDD. Yoga is an ideal complementary and alternative therapy for mental health disorders.

Summary of the effect of an exercise intervention on antenatal depression and the optimal program: a systematic review and Meta-analysis

OBJECTIVE

This study aimed to examine the effect of exercise intervention for antenatal depression using meta-analysis and to propose the best exercise intervention program.

METHODS

Review Manager 5.3 was used to analyze 17 papers with 2224 subjects by setting five moderators, including type, time, frequency, period, and format of exercise intervention, and a random-effects model was used to test for overall effect, heterogeneity, and publication bias.

RESULTS

(1) The effect size of the exercise intervention on antenatal depression was d = -0.56, which reached a good effect and was statistically significant; b (2) The effect size of the exercise type on antenatal depression was Yoga and a combination of aerobic exercise in order of intervention; (3) the single intervention duration of 10-75 min all had a good effect on antenatal depression, and 30-60 min had the best effect; (4) the intervention frequency of 3 to 5 times/week had the greatest amount of intervention effect on maternal depression; (5) exercise lasting 6-10 weeks had a good intervention effect on antepartum depression, and the amount of effect decreased gradually with the extension of time; (6) In terms of exercise format, the amount of intervention effect on maternal depression was in the order of group exercise, individual + group exercise.

CONCLUSIONS

Exercise intervention can significantly alleviate antenatal depression symptoms. The best exercise program for exercise intervention for antenatal depression is: Yoga and a combination of aerobic exercise intervention effects are more prominent, and the intervention effect of Yoga is the best. The use of group exercise 3-5 times per week for 30-60 min for 6-10 weeks was more likely to achieve the desired intervention effect of improving antenatal depression.

Assessing feasibility and acceptability of yoga and group CBT for adolescents with depression: A pilot randomized clinical trial

PURPOSE

Given increasing rates of depression in adolescents, there is a clear need for innovative treatments. In this pilot randomized clinical trial, we assessed acceptability and feasibility of two group-based interventions: yoga and cognitive-behavioral therapy (CBT). The goal of this work is to prepare for a future fully powered randomized trial to test the hypothesis that yoga is not inferior to an established adolescent depression treatment, namely, group CBT.

METHODS

We enrolled 42 adolescents with elevated depression symptoms. Participants were randomly assigned to a 12-week group-based intervention, yoga or CBT. We had a priori feasibility and acceptability targets, including for recruitment rate, retention rate, expectancy, credibility, program satisfaction, class attendance, engagement in home practice, and instructor/leader manual adherence. We assessed adverse events, and within-subject changes in outcomes (depression, anxiety, impairment, sleep disturbance) and possible mediators (mindfulness, self-compassion).

RESULTS

Both interventions met most acceptability and feasibility targets. The only target not met related to low engagement in home practice. Participants within each study arm showed decreased depression symptoms over time and increased self-compassion.

CONCLUSIONS

A yoga intervention appears to be acceptable and feasible to adolescents with depression. However, it may be challenging for this group to engage in unstructured home practice.

Integration of yoga within exercise and sports science as a preventive and management strategy for musculoskeletal injuries/disorders and mental disorders - A review of the literature

OBJECTIVES

Exercise-induced musculoskeletal injuries/disorders and associated mental disorders are prevalent among athletes. The main objective of this review is to analyze the prospects of Yoga practices as a preventive and management strategy for musculoskeletal injuries/disorders and associated mental disorders often encountered in exercise and sports activities.

METHODS

A review of the literature was performed using electronic databases such as MEDLINE/PubMed and google scholar published between January 1991 and December 2021 which yielded 88 research articles. The keywords used were yoga OR exercise AND musculoskeletal injuries OR disorders, yoga OR exercise AND mental disorders, yoga AND sports injuries, yoga AND stress, yoga OR exercise AND oxidative stress, yoga OR exercise AND inflammation, yoga OR exercise AND diet.

RESULTS

The moderate and regular exercises are beneficial to health. However, high intensity and overtraining physical activities lead to immune suppression, oxidative stress, muscle damage/fatigue, coronary risk, psychiatric disorders and so on due to enormous strain on various physiological functions. Yoga seems to undermine these adverse activities through up-regulating the functions of the parasympathetic nervous system (PNS) and down-regulating the activities of hypothalamohypophysial axis (HPA) which are conducive to healing, recovery, regeneration, reduction in stress, relaxation of mind, better cognitive functions, promotion of mental health, reduction in inflammation and oxidative stress, and so on.

CONCLUSION

Literature suggests that Yoga should be integrated within exercise and sports sciences mainly to prevent & manage musculoskeletal injuries/disorders and associated mental disorders.

Effect of Yoga on Frailty in Older Adults : A Systematic Review

BACKGROUND

Yoga, a multicomponent mind-body practice, improves several domains of physical and psychological health and may affect frailty in older adults.

PURPOSE

To evaluate the available trial evidence on the effect of yoga-based interventions on frailty in older adults.

DATA SOURCES

MEDLINE, EMBASE, and Cochrane Central from their inception to 12 December 2022.

STUDY SELECTION

Randomized controlled trials evaluating the effect of yoga-based interventions, including at least 1 session of physical postures, on a validated frailty scale or single-item markers of frailty in adults aged 65 years or older.

DATA EXTRACTION

Two authors independently screened articles and extracted data; 1 author assessed risk of bias with review from a second author. Disagreements were resolved through consensus and as-needed input from a third author.

DATA SYNTHESIS

Thirty-three studies (n = 2384 participants) were identified in varied populations, including community dwellers, nursing home residents, and those with chronic disease. Yoga styles were primarily based on Hatha yoga and most often included Iyengar or chair-based methods. Single-item frailty markers included measures of gait speed, handgrip strength, balance, lower-extremity strength and endurance, and multicomponent physical performance measures; no studies included a validated definition of frailty. When compared with education or inactive control, there was moderate-certainty evidence that yoga improved gait speed and lower-extremity strength and endurance, low-certainty evidence for balance and multicomponent physical function measures, and very low-certainty evidence for handgrip strength.

LIMITATION

Heterogeneity in study design and yoga style, small sample sizes, and reporting deficiencies leading to concerns for selection bias.

CONCLUSION

Yoga may affect frailty markers that are associated with clinically meaningful outcomes in older adult populations but may not offer benefit over active interventions (for example, exercise).

PRIMARY FUNDING SOURCE

None. (PROSPERO: CRD42020130303).

Effects of Suryanamaskar, an Intensive Yoga Exercise Routine, on the Stress Levels and Emotional Intelligence of Indian Students

The inability of an individual to identify, assess, and manage emotions and levels of stress has adverse individual and societal consequences. Previous studies have shown that yoga-based interventions can successfully treat stress, anxiety, and depression, and can enhance emotional control. The aim of the current study was to assess the effect of a specific, intensive, yoga-based intervention, Dynamic Suryanamaskar, on the levels of perceived stress and emotional intelligence in Indian male school students. One hundred and five students with a median age of 17.15 ± 1.42 years were assessed. Practice took place over 12 weeks (n = 70 workouts). The Perceived Stress Scale (PSS) questionnaire and the emotional intelligence (EQ) questionnaire, developed for the Indian population, were used to measure stress and emotional levels at the start and end of the study. The Solomon four-group design was used to ensure statistical reliability. The post-study univariate analysis of covariance ANOVA between groups (p < 0.001) and the t-test for independent samples (p < 0.05) indicated that, for those using the Dynamic Suryanamaskar protocol, there was a significant reduction in stress levels and a significant (p < 0.01) increase in the levels of emotional intelligence. This study thus provides further evidence of the benefits of the practice of Dynamic Suryanamaskar.

CE: An Evidence-Based Yoga Practice for Hospitalized Adults on Medical-Psychiatric Units

BACKGROUND

Yoga-based treatments, which are recognized by the National Institutes of Health's National Center for Complementary and Integrative Health as a form of complementary and alternative medicine, have proven to be beneficial for people with various psychiatric disorders, including depression, anxiety, posttraumatic stress disorder, and attention deficit-hyperactivity disorder, as well as schizophrenia and other psychotic disorders.

PURPOSE

The purpose of this evidence-based practice (EBP) project was to offer structured yoga sessions as a means of providing stress relief, promoting relaxation, reducing anxiety, and improving quality of care among male and female adult patients (ages 18 years and older) hospitalized in a locked medical-psychiatric unit within an academic medical center for treatment of both acute medical and acute psychiatric conditions.

PRACTICE CHANGE AND IMPLEMENTATION

The Iowa Model and Implementation Strategies for EBP provided the guiding framework for this pilot project. Patients were offered once weekly, 30-to-60-minute yoga sessions for 12 weeks and were screened for their ability to participate by the nurse-yoga instructor and the interprofessional team. Using a Precision Implementation Approach, a data-driven selection of strategies from the implementation framework promoted the adoption and sustainability of the practice change, which were further advanced through interprofessional reinforcement of yoga practice and internal reporting.

RESULTS

Patient feedback was sought before and after yoga sessions. Thirty-nine patients responded to the pre-yoga questionnaire and 38 patients responded to the post-yoga questionnaire. Patients reported improved mood after yoga, with 23% (nine of 39) reporting feelings of calm and relaxation pre-yoga compared with 76% (29 of 38) post-yoga, and 41% (16 of 39) reporting feelings of anxiety pre-yoga compared with just 5% (two of 38) post-yoga.

CONCLUSION

Yoga sessions provided by a nurse certified in yoga instruction improved patients' mood and sense of well-being. Instructional materials and videos were created to promote sustained use. The EBP of providing yoga sessions grew from a pilot program to a sustained change with more widespread use. In addition to patients hospitalized on medical-psychiatric units, the health system expanded the sessions to include inpatients on behavioral health units.

A pragmatic preference trial of therapeutic yoga as an adjunct to group cognitive behaviour therapy versus group CBT alone for depression and anxiety

BACKGROUND

Yoga has several mechanisms that make it a promising treatment for depression and anxiety, including physical activity, behavioural activation, and mindfulness. Following positive outcomes from adapted CBT interventions incorporating mindfulness-based practices, this study explored the effects of a therapeutic yoga program as an adjunct to group-based CBT for depression or anxiety.

METHODS

This was a pragmatic preference trial involving adults diagnosed with depression or anxiety in a regional primary mental healthcare service (n = 59), comparing transdiagnostic group CBT (n = 27) with transdiagnostic group CBT combined with an adjunct therapeutic yoga program (n = 32). A preference recruitment design allowed eligible participants (n = 35) to self-select into the adjunct program. The Depression Anxiety Stress Scale-21 (DASS) was assessed at baseline, post-intervention, and three-months follow up.

RESULTS

CBT + Yoga was an acceptable alternative to CBT alone. Significant reductions were observed in total DASS scores and the 3 subscales of the DASS for both groups, however CBT + Yoga showed significantly lower depressive and anxiety symptoms post-intervention, compared to CBT alone. CBT + Yoga also showed sustained reductions in depressive symptoms over three-months, and more rapid reductions in depressive symptoms, compared to CBT alone.

LIMITATIONS

These findings should be considered preliminary due to the moderate sample size, with a rigorous randomised control trial necessary to definitively support the integration of yoga within mental health care to augment the benefits and uptake of transdiagnostic CBT for depression and anxiety.

CONCLUSIONS

Complementing other mindfulness-based practices, therapeutic yoga shows promise as an adjunct to transdiagnostic CBT.

Role of Yoga practices on cognitive functions

Yoga is the science of conditioning one's mind and body via the practise of shatkarma, asana, pranayama, mudra, and meditation. The aim of this review of literature is to give theoretical rationale for identifying (a) the specific attributes of yoga poses that have been used in yoga protocols of various studies but have not been explicitly explored, & (b) the minimum time necessary to keep a posture to bring about a corresponding change in performance among the aforementioned cognitive functions (s) In humans, The most prevalent and under-treated problems are cognitive decline & psychological health problems. Different studies have been carried out to determine the influence of Yoga on human cognitive and psychological health indices. However, no comprehensive examination of the effects of yoga-based therapy on human cognitive and mental health has been undertaken to far. Yoga is an ancient science that places a premium on disease prevention and treatment, as well as the percentage of health. Yoga is recognized to delay the effects of aging and has been found to be effective in the therapy of aging-related disorders. Yoga is a centuries-old discipline that is said to improve both physical and emotional well-being.

Integration of hatha yoga and evidence-based psychological treatments for common mental disorders: An evidence map

BACKGROUND

Interest in the use of yoga to enhance engagement with and augment the benefits of psychological treatment has grown. However, a systematic approach to reviewing existing research examining the use of yoga with psychological treatment is lacking.

MATERIALS AND METHODS

This mapping review identified and synthesised research trialling yoga as an integrated or adjunct therapy with evidence-based psychological interventions for the treatment of anxiety, depression, PTSD, and eating disorders.

RESULTS

Overall, the review identified ten published and three unpublished studies, representing either single group or small quasi-experimental research designs.

DISCUSSION

Limited but promising findings were shown for yoga with CBT for anxiety and depression, and the integration of yoga within intensive treatment models for PTSD.

CONCLUSIONS

Future research is encouraged to focus on controlled trials that enable examination of the component effect of yoga when applied with evidence-based psychological treatment and acceptability and feasibility data to further knowledge regarding a role for yoga in clinical practice.

Single-arm Pilot Trial of Hatha Yoga for Adolescents with Depression

The prevalence of adolescent depression is increasing, particularly among girls. Existing evidence-based treatments have limitations and/or may not be acceptable to all adolescents and parents. There is evidence that hatha yoga may be useful as an adjunctive treatment for depression in adults. The purpose of the current study was to assess acceptability and feasibility of hatha yoga for depression in teens. We conducted a single-arm pilot trial of 12 weeks of manualized yoga classes specifically targeted toward teens with elevated depression symptoms. We assessed acceptability and feasibility by several metrics and compared our results against a priori benchmarks. We also collected qualitative feedback on the classes. We enrolled 11 teens. We met a priori benchmarks for recruitment and retention rates, credibility of the yoga classes, satisfaction with classes, and (lack of) adverse events causally related to classes. Class attendance and amount of home practice fell below planned benchmarks. Qualitative feedback was positive from the majority, although not all, participants. Results from this study may be used to further refine yoga classes for depressed teens.

The mindfulness trajectories of addressing suicidal behaviour: A systematic review

BACKGROUND AND OBJECTIVES

Suicidal behaviour has been a persistent concern in medical as well as general settings. Many psychotherapeutic approaches have tried to address suicidal behaviour in different ways. Mindfulness-based interventions (MBIs) have garnered much attention in the last decade because of their treatment efficacy. This systematic review aimed to examine evidence-based research regarding the effectiveness of MBIs as a psychotherapy intervention on suicidality and to deliver suggestions that might help future research.

METHOD

The identification of literature was made through an extensive search of the electronic databases, to extract studies relating to the efficacy of MBIs on addressing suicidal behaviour. Additional researches based on library sources were searched manually. The studies' selection was based on a pre-determined inclusion and exclusion criteria as well as the quality of the studies.

RESULTS

The present review helped us identify 13 studies, including six randomised controlled trials, two controlled studies and five pre-post observational studies. The findings reported in the studies were mostly favourable to MBIs as an effective intervention strategy for suicidal behaviour.

CONCLUSION

MBIs show promising effects as an intervention for suicidal behaviour. However, large scale, high-quality trials with active control, and long term intervention efficacy studies are needed to understand the mechanisms through which MBIs reduce suicidal behaviour.

Feasibility of Integration of Yoga in a Behavioral Weight-Loss Intervention: A Randomized Trial

OBJECTIVE

This study examined the feasibility and comparison of two styles of yoga within the context of a standard behavioral weight-loss intervention (SBWI).

METHODS

Fifty adults with obesity (BMI: 31.3 ± 3.8 kg/m² ) participated in this 6-month study that included a SBWI and a calorie- and fat-reduced diet. Randomization was to restorative Hatha (SBWI+RES) or Vinyasa (SBWI+VIN) yoga. Yoga was prescribed to increase from 20 to 40 to 60 minutes per session across the intervention. Weight was assessed at baseline and 6 months. Perceptions of yoga were assessed at the completion of the intervention.

RESULTS

Adjusted weight loss was -3.4 kg (95% CI: -6.4 to -0.5) in SBWI+RES and -3.8 kg (95% CI: -6.8 to -0.9) in SBWI+VIN (P < 0.001), with no difference between groups. Of all participants, 74.4% reported that they would continue participation in yoga after the SBWI. Session duration was a barrier as yoga increased from 20 to 40 to 60 minutes per day, with 0%, 7.5%, and 48.8% reporting this barrier, respectively.

CONCLUSIONS

Among adults with obesity, yoga participation, within the context of a SBWI, appears to be feasible, with weight loss not differing by style of yoga. Progressing to 60 minutes per session appears to be a barrier to engagement in yoga in this population.

Yoga, Health-Related Quality of Life and Mental Well-Being: A Re-analysis of a Meta-analysis Using the Quality Effects Model

BACKGROUND

Provide robust and practically relevant information regarding the association between yoga, health-related quality-of-life (HRQOL), and mental well-being (MWB) in older adults.

METHODS

Data were derived from a recent meta-analysis of 12 randomized controlled yoga trials representing 752 adults ≥60 years of age. Standardized mean difference effect sizes (ESs) were pooled using the recently developed quality effects model and 95% compatibility intervals (CI). Small-study effects were examined using the Doi plot and Luis Furuya-Kanamori (LFK) index. Sensitivity and cumulative meta-analyses were conducted as well as percentile improvement, number needed to treat (NNT), and number to benefit. The grading of recommendations assessment, development, and evaluation (GRADE) instrument was used to assess the strength of the evidence.

RESULTS

Yoga was associated with improvements in both HRQOL (ES = 0.51, 95% CI, 0.25-0.77, I2 = 63.1%) and MWB (ES = 0.39, 95% CI, 0.15-0.63, I2 =56.2%). Percentile improvements were 19.5 for HRQOL and 15.3 for MWB whereas the NNT was 4 for HRQOL and 5 for MWB. An estimated 378,222 and 302,578 U.S. yoga-practicing adults ≥65 years of age could potentially improve their HRQOL and MWB, respectively. Major asymmetry suggestive of small-study effects was observed for MWB but not HRQOL. Further examination for asymmetry revealed that greater improvements in MWB were associated with more (151 vs. 68) minutes of yoga per week (p = .007). Overall strength of evidence was considered "high" for HRQOL and "moderate" for MWB.

CONCLUSIONS

Yoga is associated with improvements in HRQOL and MWB among older adults, with approximately 150 minutes or more per week possibly optimal.

Development of Sham Yoga Poses to Assess the Benefits of Yoga in Future Randomized Controlled Trial Studies

Background: Although research has demonstrated the benefits of yoga to people who have been diagnosed with diabetes or at risk of diabetes, studies have not confirmed these effects can be ascribed to the specific features of the traditional postures, called asanas. Instead, the effects of asanas could be ascribed to the increase in cardiovascular activity and expenditure of energy or to the expectation of health benefits. Therefore, to establish whether asanas are beneficial, researchers need to design a control condition in which participants complete activities, called sham poses, that are equivalent to traditional asanas in physical activity and expectation of benefits. Objectives: The aim of this research was to design an appropriate suite of sham poses and to demonstrate these poses and traditional asanas are equivalent in energy expenditure, cardiovascular response, and expectations of health benefits. Methods: Twenty healthy men at medium to high risk of developing diabetes volunteered to partake in the current study. These men completed two sessions that comprised traditional asanas and two sessions that comprised sham poses—poses that utilize the same muscle groups as the asanas and were assigned fictitious Sanskrit labels. Before and after each session, heart rate, blood pressure, blood glucose levels, triglycerides levels, and oxygen saturation were measured to gauge the intensity of exercise. After each session, using a standard measure, participants also indicated the degree to which they expected the poses to improve health. Results: The degree to which the sessions affected the physiological measures (for example, pre-exercise, the heart rate for yoga and sham was 71.06 ± 4.79 and 73.88 ± 6.05, respectively, and post-exercise, the heart rate was 70.19 ± 6.16 and 73 ± 7.55, respectively) and the expectations of health improvements did not differ between the traditional asanas and the sham poses. Likewise, the degree to which each session influenced these physiological measures was negligible in both conditions. Conclusions: This study developed a series of poses that elicit similar physiological and psychological effect as traditional yoga asanas. These poses can be used in an active control group in future randomized trial studies that are designed to assess the benefits of asanas.

Randomized controlled trial of bikram yoga and aerobic exercise for depression in women: Efficacy and stress-based mechanisms

BACKGROUND

The current study presents a randomized controlled 8-week trial of Bikram yoga, aerobic exercise, and waitlist for depression. Bikram yoga was chosen specifically for its standardized nature. Further, we examined changes in three stress-related constructs-perceived stress, rumination, and mindfulness-as mediators of antidepressant effects.

METHOD

Fifty-three women (age 18-65; 74% White) with a unipolar depressive disorder were randomly assigned to one of the three conditions. Response was defined as >50% reduction on the Hamilton Rating Scale for Depression (HAM-D). Remission was defined as no longer meeting criteria for depression and a HAM-D ≤ 7. Self-reported perceived stress, rumination, and mindfulness were assessed weekly.

RESULTS

In the intention-to-treat sample (n = 53), response rates were significantly higher in the Bikram yoga (61.1%; χ² = 10.48, p = .001) and aerobic exercise (60.0%; χ² = 10.44, p = .001) conditions relative to waitlist (6.7%). In the completer sample (n = 42), 73.3% (χ² = 11.41, p = .001) of women in yoga and 80.0% (χ² = 13.72, p < .001) in exercise achieved response compared to 8.3% in waitlist. Reductions in rumination significantly mediated HAM-D change for both active treatments, and mindful acceptance was a partial mediator in the exercise condition.

LIMITATIONS

The sample was small in size, consisted of women only, and was ethnically homogenous. Inter-rater reliability was not assessed, aerobic exercise was not standardized, and mediators were assessed by self-report.

CONCLUSIONS

Bikram yoga showed descriptively similar efficacy to aerobic exercise and both may work, in part, by helping individuals interrupt negative thinking.

Complementary and alternative treatments for insomnia/insomnia -depression-anxiety symptom cluster: Meta-analysis of English and Chinese literature

This study systematically reviewed randomized controlled trials (RCT), published in English or Chinese, investigating the effect of complementary and alternative medicines (CAM) on significant insomnia/poor sleep quality and accompanying depression and/or anxiety symptoms. A meta-analysis was completed by calculating within-group effect size (ES) of each CAM treatment on sleep, depression and/or anxiety measures. Moderating analyses of study quality, language, treatment duration and presence of physical diseases were conducted to evaluate their impact on ESs. Between-group ES of CAM (vs. non-specific/placebo controls) were computed among high-quality studies. From an initial pool of 5047 articles, a total of 72 studies were included in the meta-analysis (44 in English; 28 in Chinese). All CAM modalities yielded significant, moderate to large effect sizes on sleep, depression, and anxiety symptoms yet with high heterogeneity. Significant between-group differences on sleep measures were found only between mindfulness-based treatment and non-specific/placebo controls. Chinese literature are associated with larger ESs. Future study should examine the presence and nature of the active components in different CAM approaches.

Effects of body-oriented yoga: a RCT study for patients with major depressive disorder

The major depressive disorder is one of the most common mental illnesses worldwide. Current treatment standards recommend a combined therapy with medication and psychotherapy. As an additive component and to further improvements in treatment, physical activity such as yoga may be integrated into conventional treatment. This study investigates the impact of a 3-month body-oriented yoga in patients with major depressive disorder (MDD). In total, n = 83 patients were included. An intervention group received a vigorous Ashtanga-Yoga three times a week. The waiting-list control group obtained a treatment as usual (TAU). As a primary outcome depression scores (Beck Depression Inventory-II (BDI-II), Montgomery Asberg Depression Rating Scale (MADRS)) were tested at three time points. Secondary outcome was the positive and negative affect [Positive and Negative Affect Scale (PANAS)] and remission rates. To analyze the data, multilevel models and effect sizes were conducted. The results showed an improvement in BDI-II scores for both groups over time [γ =  -  3.46, t(165) =  - 7.99, p < 0.001] but not between groups [γ = 0.98, t(164) = 1.12, p = 0.263]. An interaction effect (time x group) occurred for MADRS [γ = 2.10, t(164) = 2.10, p < 0.038]. Positive affects improved over time for both groups [γ = 1.65, t(165) = 4.03, p < 0.001]. Negative affects decreased for all over time [γ =  -  1.00, t(165) = - 2.51, p = 0.013]. There were no significant group differences in PANAS. Post hoc tests revealed a greater symptom reduction within the first 6 weeks for all measurements. The effect sizes for depression scores showed a positive trend. Remission rates indicated a significant improvement in the yoga group (BDI-II: 46.81%, MADRS: 17.02%) compared to the control group (BDI: 33.33%, MADRS: 8.33%). The findings suggest that there is a trendsetting additive effect of Ashtanga-Yoga after 3 months on psychopathology and mood with a greater improvement at the beginning of the intervention. Further research in this field can help to achieve more differentiated results.

Is yoga considered exercise within systematic reviews of exercise interventions? A scoping review

OBJECTIVE

Yoga is an increasingly popular choice of exercise for the Western population, with people engaging in yoga for a range of physical and mental health and well-being reasons. The aim of this scoping review is to examine whether yoga is considered an exercise modality within relevant leading journals, as evidenced by its consideration in systematic reviews (SRs) of exercise interventions for health-related outcomes.

METHODS

Design: Scoping review.

DATA SOURCES

Three leading sources (Sports Medicine, British Journal of Sports Medicine and Cochrane Collaboration) were searched. Eligibility criteria for selecting studies: The ten most recently published systematic reviews of exercise interventions for health-related outcomes from each journal were included (N = 30) that met these criteria: systematic review studying humans participating in general exercise and measuring a health-related outcome. Exercise interventions with any specific qualifying terms (e.g. aquatic, strength, aerobic) were excluded.

RESULTS

The articles retrieved were published between 2007 and 2019, and collectively included 991 interventions. Seven reviews explicitly stated that yoga was to be included/excluded while twenty-three studies made no mention of how yoga was being considered in the methodology. Five studies included yoga in the search strategy, implying its inclusion. Post-hoc analyses found that the definitions of exercise in general were also variable. Exercise definition specificity was not associated with whether or not yoga was assessed for inclusion.

CONCLUSIONS

Systematic reviews of exercise and physical activity interventions for health-related outcomes do not consistently make clear whether or not they include or exclude yoga as a form of exercise.

Benefits of Yoga on IL-6: Findings from a Randomized Controlled Trial of Yoga for Depression

The present research sought to examine whether hatha yoga, implemented as an adjunctive intervention for major depression, influences markers of inflammation. A subset of 84 participants who were enrolled in a randomized controlled trial (RCT) of hatha yoga vs. health education control provided blood samples at baseline (pre-treatment) and at 3-(during treatment) and 10-week (end of treatment) follow-up visits. To be eligible for the RCT, participants met criteria for a current or recent (past two years) major depressive episode, had current elevated depression symptoms, and current antidepressant medication use. Venous blood was drawn between 2 and 6 pm and following at least one hour of fasting, and inflammatory markers (IL-6, CRP, and TNF-α) were assayed. Effects of participation in yoga relative to health education on inflammatory markers over time were examined with latent growth analyses. We observed a significant reduction in IL-6 concentrations in the yoga treatment group relative to the health education control group as demonstrated by a negative interaction between treatment group and slope of IL-6. TNF-α and CRP did not evidence significant interactions of treatment group by mean slope or intercept. In addition to the benefits of hatha yoga as an adjunctive intervention for individuals who have shown inadequate response to antidepressant medications, our findings point to possible benefits of yoga on IL-6 in depressed populations. Further research is needed to explore the effects of hatha yoga on immune function over time.

The practicability and relevance of developing a yoga intervention for mental health consumers: A qualitative study

The aim of the study was to understand the perspectives of mental health consumers, staff, and yoga teachers on the characteristics of a yoga-based intervention to be developed for consumers with a long-term mental health condition, in addition to anxiety and/or depression. Two focus groups were held with mental health consumers (n = 8), two focus groups with mental health staff (n = 13) from a metropolitan community mental health setting, and five one-on-one interviews with yoga teachers. Participants were asked about the feasibility and appropriateness of a range of yoga practice features to be tested as a newly developed yoga-based intervention. Thematic analysis was used to identify themes. Findings included the following consumer themes: Mental health understanding and experience of teachers and participants is important, Creating a safe space and Yoga practice elements. Staff themes included Mental health understanding and experience of teachers is important, Environmental design, and Yoga practice elements. Yoga teacher themes included Environmental design and Yoga practice elements. Mental health understanding and experience of the yoga teacher, and trauma-informed care were consistently emphasized by consumers and staff. Teachers focused less on specific mental health considerations, which may be reflective of a broader knowledge gap. Recommendations regarding yoga practice elements, including pre-information, regular and consistent practice, modifications, breathwork, mindfulness and guided practice, and environmental design features, were consistent with current trauma-informed yoga research. Findings will be used to guide the development of a yoga-based intervention for consumers with a long-term mental health condition, in addition to anxiety and/or depression.

Effects of yoga on depressive symptoms in people with mental disorders: a systematic review and meta-analysis

OBJECTIVE

To assess whether physically active yoga is superior to waitlist control, treatment as usual and attention control in alleviating depressive symptoms in people with a diagnosed mental disorder recognised by the Diagnostic and Statistical Manual of Mental Disorders (DSM).

DESIGN

Systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

DATA SOURCES

Data were obtained from online databases (MEDLINE, EMBASE, PsychINFO, CENTRAL, EMCARE, PEDro). The search and collection of eligible studies was conducted up to 14 May 2019 (PROSPERO registration No CRD42018090441).

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

We included randomised controlled trials with a yoga intervention comprising ≥50% physical activity in adults with a recognised diagnosed mental disorder according to DSM-3, 4 or 5.

RESULTS

19 studies were included in the review (1080 participants) and 13 studies were included in the meta-analysis (632 participants). Disorders of depression, post-traumatic stress, schizophrenia, anxiety, alcohol dependence and bipolar were included. Yoga showed greater reductions in depressive symptoms than waitlist, treatment as usual and attention control (standardised mean difference=0.41; 95% CI -0.65 to -0.17; p<0.001). Greater reductions in depressive symptoms were associated with higher frequency of yoga sessions per week (β=-0.44, p<0.01).

Thalamic Gamma Aminobutyric Acid Level Changes in Major Depressive Disorder After a 12-Week Iyengar Yoga and Coherent Breathing Intervention

Objective: To determine if a 12-week yoga intervention (YI) was associated with increased gamma aminobutyric acid (GABA) levels and decreased depressive symptoms in participants with major depressive disorder (MDD). Methods: Subjects were randomized to a high-dose group (HDG) of three YIs a week and a low-dose group (LDG) of two YIs a week. Thalamic GABA levels were obtained using magnetic resonance spectroscopy at Scan-1 before randomization. After the assigned 12-week intervention, Scan-2 was obtained, immediately followed by a YI and Scan-3. Beck Depression Inventory II (BDI-II) scores were obtained before Scan-1 and Scan-3. Settings/Location: Screenings and interventions occurred at the Boston University Medical Center. Imaging occurred at McLean Hospital. Subjects: Subjects met criteria for MDD. Intervention: Ninety minutes of Iyengar yoga and coherent breathing at five breaths per minute plus homework. Outcome measures: GABA levels and the BDI-II. Results: BDI-II scores improved significantly in both groups. GABA levels from Scan-1 to Scan-3 and from Scan-2 to Scan-3 were significantly increased in the LDG (n = 15) and showed a trend in the total cohort. Post hoc, participants were divided into two groups based on having an increase in GABA levels at Scan-2. Increases in Scan-2 GABA levels were observed in participants whose mean time between their last YI and Scan-2 was 3.93 ± 2.92 standard deviation (SD) days, but not in those whose mean time between their last YI and Scan-2 was 7.83 ± 6.88 SD. Conclusions: This study tentatively supports the hypothesis that one of the mechanisms through which yoga improves mood is by increasing the activity of the GABA system. The observed increase in GABA levels following a YI that was no longer observed 8 days after a YI suggests that the associated increase in GABA after a YI is time limited such that at least one YI a week may be necessary to maintain the elevated GABA levels.

Feasibility and Impact of a Yoga Intervention on Cognition, Physical Function, Physical Activity, and Affective Outcomes among People Living with HIV: A Randomized Controlled Pilot Trial

The purpose of this pilot randomized controlled trial is to assess the feasibility and impact of a triweekly 12-week yoga intervention among people living with HIV (PLWH). Additional objectives included evaluating cognition, physical function, medication adherence, health-related quality of life (HRQoL), and mental health among yoga participants versus controls using blinded assessors. We recruited 22 medically stable PLWH aged ≥35 years. A priori feasibility criteria were ≥70% yoga session attendance and ≥70% of participants satisfied with the intervention using a postparticipation questionnaire. Two participants withdrew from the yoga group. Mean yoga class attendance was 82%, with 100% satisfaction. Intention-to-treat analyses (yoga n = 11, control n = 11) showed no within- or between-group differences in cognitive and physical function. The yoga group improved over time in HRQoL cognition (P = .047) with trends toward improvements in HRQoL health transition (P =.063) and depression (P = .055). This pilot study provides preliminary evidence of feasibility and benefits of yoga for PLWH.

Innovations in the Treatment of Perinatal Depression: the Role of Yoga and Physical Activity Interventions During Pregnancy and Postpartum

PURPOSE OF REVIEW

We review evidence for physical activity and yoga as interventions for depressed pregnant and postpartum women.

RECENT FINDINGS

Results from existing trials have generally indicated that physical activity and yoga interventions are acceptable to women during the perinatal period, and that these interventions can be effective in reducing depression. However, some studies have not found significant differences between intervention and control conditions. In addition, symptom improvements were not always maintained. The available research on physical activity and yoga as interventions for perinatal depression is encouraging with regard to feasibility, acceptability, patient safety, and preliminary efficacy. These interventions have the ability to reach a large number of women who may not engage in traditional treatment. Additional high quality, rigorous, randomized controlled trials are needed. Future research is also needed to examine the optimal dose of these interventions and how to best increase sustained engagement.

Effect of adjunct yoga therapy in depressive disorders: Findings from a randomized controlled study

BACKGROUND

Depression causes significant burden both to the individual and to society, and its treatment by antidepressants has various disadvantages. There is preliminary evidence that adds on yoga therapy improves depression by impacting the neurotransmitters involved in the regulation of mood, motivation, and pleasure. Our study aimed to find the effect of adjunctive yoga therapy on outcome of depression and comorbid anxiety.

MATERIALS AND METHODS

A randomized controlled study involving patients with major depressive disorder (n = 80) were allocated to two groups, one received standard therapy (antidepressants and counseling) and the other received adjunct yoga therapy along with standard therapy. Ratings of depression and anxiety were done using Montgomery-Asberg Depression Rating Scale and Hospital Anxiety and Depression Scale at baseline, 10^th and 30^th day. Clinical Global Impression (CGI) Scale was applied at baseline and 30^th day to view the severity of illness and clinical improvement.

RESULTS

By the 30^th day, individuals in the yoga group had significantly lower scores of depression, anxiety, and CGI scores, in comparison to the control group. The individuals in the yoga group had a significant fall in depression scores and significant clinical improvement, compared to the control group, from baseline to 30^th day and 10^th to 30^th day. In addition, the individuals in the yoga group had a significant fall in anxiety scores from baseline to 10^th day.

CONCLUSION

Anxiety starts to improve with short-term yoga sessions, while long-term yoga therapy is likely to be beneficial in the treatment of depression.

Motivations for Adopting and Maintaining a Yoga Practice: A National Cross-Sectional Survey

Background: Yoga practice is becoming increasingly popular around the world, yet little is known regarding why people adopt the practice of yoga or how their reasons for practice change with continued practice. Furthermore, whether those who practice different types of yoga have different motives remains unknown. Methods: To address these issues, the authors conducted a national cross-sectional online survey of 1,702 yoga practitioners in Germany, asking about demographic information and motives for initiating and continuing yoga practice. Results: The most common primary reasons for starting yoga were relaxation (26.6%) and prevention (25.5%), which were also the most common secondary reasons. Nine hundred and forty-one (55.3%) reported a different primary reason for maintaining than for adopting yoga practice. Prevention (38.4%) and spirituality (26.4%) were the most commonly reported primary reasons for maintaining yoga practice. More highly educated participants and those practicing longer than 5 years at the time of the survey were more likely to have reported a different current primary reason for yoga practice than that for which they started practicing. Conclusions: These results shed light on yoga's appeal to novices and regular practitioners, with important implications for making yoga appealing to beginners as well as promoting the practice as a long-term lifestyle behavior.

Yoga Protocol for Cancer Patients: A Systematic Exploration of Psychophysiological Benefits

BACKGROUND

Several studies report that practicing Yoga may lead to numerous psychophysiological benefits in patients undergoing treatment for cancer. Moreover, it may result in an effective alternative for coping with sleep disturbances, anxiety, depression and fatigue symptoms. A study based on the "Yoga in Oncology" project of the Foundation Poliambulanza was carried out, and it was designed to explore the benefits of Yoga, therefore corroborating Yoga as a therapeutic activity that can have a beneficial impact on patients diagnosed with cancer.

METHODS

Seventy patients were recruited, of whom 20% were males and 80% were females 18 years of age and older. All patients were being treated at the oncology department for gastrointestinal, mammary or genital carcinoma, and the disease was metastatic in 80% of patients. Data were collected between April 2013 and May 2017. The protocol consisted of a weekly 90-minute Yoga lesson for 8 consecutive weeks, and the data collection was carried out in 2 phases: (T0) preprotocol assessment and (T1) postprotocol assessment. Psychophysiological assessment was carried out with the following scales: the (BFI) Brief Fatigue Inventory, (HADS) Hospital Anxiety and Depression Scale and (PSQI) Pittsburgh Sleep Quality Index.

RESULTS

Data analysis showed a significant difference between the (T0) and (T1) HADS (Hospital Anxiety and Depression Scale) scores. The constructs of this scale consist of psychological variables for the assessment of anxiety and depression. In contrast, scores from the (BFI) Brief Fatigue Inventory and (PSQI) Pittsburgh Sleep Quality Index did not show significant differences between (T0) and (T1): such scales are relative to psychophysiological variables for an assessment of the perception of fatigue and quality of sleep.

CONCLUSION

It is noteworthy that the data, once analyzed, showed a significant difference between preprotocol and postprotocol levels of anxiety and depression but not for the perception of fatigue or the quality of sleep. In accordance with the scientific literature, data from this study highlight that practicing Yoga may promote changes in the levels of perceived anxiety and depression in patients undergoing treatment for cancer, thus positively affecting their (QoL). It is clear that the difference in significance between the psychological and physiological variables considered here and the statistical significance found only in levels of anxiety and depression encourage further studies to account for the nature of fatigue and sleep disturbances and how to address these symptoms in oncological patients. Moreover, other points of interest for future clinical research regard the evaluation of the reason for the possible denial to participate to this kind of study, as well as the social-cultural differences in patients' behavior.

Community-Delivered Heated Hatha Yoga as a Treatment for Depressive Symptoms: An Uncontrolled Pilot Study

Objectives: There are no known studies of concurrent exposure to high temperature and yoga for the treatment of depression. This study explored acceptability and feasibility of heated (Bikram) yoga as a treatment for individuals with depressive symptoms. Design: An 8-week, open-label pilot study of heated yoga for depressive symptoms. Subjects: 28 medically healthy adults (71.4% female, mean age 36 [standard deviation 13.57]) with at least mild depressive symptoms (Hamilton Rating Scale for Depression [HRSD-17] score ≥10) who attended at least one yoga class and subsequent assessment visit. Intervention: Participants were asked to attend at least twice weekly community held Bikram Yoga classes. Assessments were performed at screening and weeks 1, 3, 5, and 8. Hypotheses were tested using a modified-intent-to-treat approach, including participants who attended at least one yoga class and subsequent assessment visit (N = 28). Results: Almost half of our subjects completed the 8-week intervention, and close to a third attended three quarters or more of the prescribed 16 classes over 8 weeks. Multilevel modeling revealed significant improvements over time in both clinician-rated HRSD-17 (p = 0.003; d_GLMM = 1.43) and self-reported Beck Depression Inventory (BDI; p < 0.001, d_GLMM = 1.31) depressive symptoms, as well as the four secondary outcomes: hopelessness (p = 0.024, d_GLMM = 0.57), anxiety (p < 0.001, d_GLMM = 0.78), cognitive/physical functioning (p < 0.001, d_GLMM = 1.34), and quality of life (p = 0.007, d_GLMM = 1.29). Of 23 participants with data through week 3 or later, 12 (52.2%) were treatment responders (≥50% reduction in HRSD-17 score), and 13 (56.5%) attained remission (HRSD score ≤7). More frequent attendance was significantly associated with improvement in self-rated depression symptoms, hopelessness, and quality of life. Conclusions: The acceptability and feasibility of heated yoga in this particular sample with this protocol warrants further attention. The heated yoga was associated with reduced depressive symptoms, and other improved related mental health symptoms, including anxiety, hopelessness, and quality of life.

Perceived mechanisms of change in therapeutic yoga targeting psychological distress

INTRODUCTION

This study was designed to investigate yoga teachers' and yoga therapists' perceptions of the ways yoga is applied to treat symptoms of psychological distress, and identify the defining features, main components, and mechanisms of change in therapeutic practice.

METHODS

A qualitative design was employed. Six yoga teachers who had specific training and experience in teaching therapeutic yoga or practicing 'yoga therapy' took part in one-to-one interviews during which they gave accounts of their experiences of helping people cope with psychological distress through yoga. Participants' interviews were transcribed verbatim and were analysed using an integrative inductive-deductive thematic analysis.

RESULTS

Four key themes were identified in relation to the benefits of therapeutic yoga: Awareness, Choice, Relationships, and Tailoring.

CONCLUSIONS

The findings support previous research which suggests that individualised yoga therapy is a promising intervention, and may help to form a theoretical rationale for the future treatment of psychological distress with yoga.

The benefits of yoga for people living with HIV/AIDS: A systematic review and meta-analysis

BACKGROUND

People living with HIV/AIDS (PLWHA) often experience psychological stress associated with disease management. This meta-analysis examines the benefits of yoga interventions on psychological distress among PLWHA.

METHODS

Included were studies that (a) evaluated a yoga intervention in PLWHA; (b) provided between-group or within-group changes; and (c) assessed a psychological, physiological, or biomedical outcome.

RESULTS

Seven studies sampling 396 PLWHA (M age = 42 years, SD = 5 years; 40% women) met inclusion criteria. PLWHA who received yoga interventions reported significant improvements in perceived stress (d+ = 0.80, 95% Confidence Interval [CI] = 0.53, 1.07), positive affect (d + = 0.73, 95% CI = 0.49, 0.98), and anxiety (d+ = 0.71, 95% CI = 0.27, 1.14) compared to controls.

CONCLUSION

Yoga is a promising intervention for stress management. However, the literature is limited by the small number of studies. Randomized controlled trials with objective measures of HIV-related outcomes are needed to further evaluate the benefits of yoga.

The Daily Influences of Yoga on Relational Outcomes Off of the Mat

Background

Despite the wide array of health benefits that have been evidenced with yoga, a clear gap exists examining how yoga impacts connections with oneself and to others.

Aims

The objectives of the present study were twofold: (1) to describe the day-to-day (in)variability in daily yoga practice and relational outcomes and (2) to examine the direct and indirect effects of yoga practice on relational outcomes.

Methods

Community-dwelling yoga practitioners (n = 104, age range: 18-76 years) with a yoga practice of at least once a week were recruited for a 21-day daily diary study. Practitioners were asked to complete daily Internet surveys at the end of the day which included questions with respect to one's yoga practice and relational domains (i.e., mindfulness, [self-]compassion, and social connectedness).

Results

Multilevel analyses revealed yoga and relational outcomes to be dynamic phenomena, indicated by substantial variation (intraclass correlations = 0.34-0.48) at the within-person level. On days when an individual practiced more yoga than their usual, greater mindfulness (b = 2.93, standard error [SE] = 0.39, P < 0.05) and self-compassion (b = 1.45, SE = 0.46, P < 0.05) were also reported. 1-1-1 multilevel mediation models demonstrated that yoga has an indirect effect on both compassion and social connectedness through increases in mindfulness at the within- and between-person levels. In models testing self-compassion as the mediator, the indirect effect of daily yoga practice on compassion was significant, although limited to the within-person level.

Conclusions

These findings suggest that a routine yoga practice could positively impact how a practitioner relates to theirselves and to others, both on a day-to-day basis, and with accumulated practice.

Role of Yoga and Mindfulness in Severe Mental Illnesses: A Narrative Review

Background:

Yoga has its origin from the ancient times. It is an integration of mind, body, and soul. Besides, mindfulness emphasizes focused awareness and accepting the internal experiences without being judgemental. These techniques offer a trending new dimension of treatment in various psychiatric disorders.

Aims:

We aimed to review the studies on the efficacy of yoga and mindfulness as a treatment modality in severe mental illnesses (SMIs). SMI includes schizophrenia, major depressive disorder (MDD), and bipolar disorder (BD).

Methods:

We conducted a literature search using PubMed, Google Scholar, and Cochrane Library with the search terms “yoga,” “meditation,” “breathing exercises,” “mindfulness,” “schizophrenia spectrum and other psychotic disorders,” “depressive disorder,” and “bipolar disorder” for the last 10-year period. We also included relevant articles from the cross-references.

Results:

We found that asanas and pranayama are the most commonly studied forms of yoga for schizophrenia. These studies found a reduction in general psychopathology ratings and an improvement in cognition and functioning. Some studies also found modest benefits in negative and positive symptoms. Mindfulness has not been extensively tried, but the available evidence has shown benefits in improving psychotic symptoms, improving level of functioning, and affect regulation. In MDD, both yoga and mindfulness have demonstrated significant benefit in reducing the severity of depressive symptoms. There is very sparse data with respect to BD.

Conclusion:

Both yoga and mindfulness interventions appear to be useful as an adjunct in the treatment of SMI. Studies have shown improvement in the psychopathology, anxiety, cognition, and functioning of patients with schizophrenia. Similarly, both the techniques have been established as an effective adjuvant in MDD. However, more rigorously designed and larger trials may be necessary, specifically for BD.

Combining group psychotherapy and yoga exercises improves quality of life in mental health professionals: a controlled randomized clinical trial

Purpose

This study aims to investigate the effects of combining 12-week group psychotherapy with yoga exercises on stress perception and quality of life in mental health professionals.

Design/methodology/approach

This study was a parallel-arm randomized controlled trial, in which the participants was unaware of which group was the experimental one. Participants involved in our research were assigned to two groups of separate treatment that followed for three months group psychotherapy combined with yoga program for stress management or usual stress coping strategies.

Findings

The findings did not reveal a significant difference in stress perception assessed in the two groups either before or after intervention but reveal a significant difference in the quality of life in the two groups before and after the psycho behavioral interventions.

Originality/value

The findings did not reveal a significant difference in stress perception assessed in the two groups either before or after intervention but reveal a significant difference in the quality of life in the two groups before and after the psycho behavioral interventions.

Feasibility of a Brief Yoga Intervention for Improving Acute Pain and Distress Post Gynecologic Surgery

BACKGROUND

Women undergoing surgical procedures for suspected gynecologic malignancies frequently experience pain and psychological distress related to surgery. Yoga may reduce these negative surgical outcomes. The primary objective of this pilot study was to assess the feasibility of evaluating a perioperative brief Yoga Skills Training (YST) in this population. Secondary objectives were to (1) assess the immediate effects of the YST on pain and psychological distress; and (2) provide preliminary data for future studies.

METHOD

Adult women scheduled to undergo an exploratory laparotomy for a suspected gynecologic malignancy were recruited to this one-arm feasibility study. Each woman received the YST, which consisted of three 15-minute sessions, one before and two after surgery. The following constructs were assessed: feasibility (rates of accrual, intervention adherence, measure completion, retention, and level of satisfaction), immediate effects of the YST (visual analogue scale ratings of pain and distress immediately before and after each session), and descriptive statistics for measures to be used in future studies.

RESULTS

Of the 33 eligible women, 18 were approached and 10 agreed to participate (mean age = 54.7 years; 90% White). Two women discontinued the study prior to starting the YST sessions. Of the eight participants who received the YST, five completed the pre-surgery session (63%) and seven completed (88%) both post-surgical sessions; one woman withdrew after one YST session. Participants reported high satisfaction with the YST. Acute pain and distress decreased from before to immediately after the YST session with moderate to large effects: pain, d's = -0.67 to -0.95; distress, d's = -0.66 to -1.08.

CONCLUSIONS

This study demonstrated reasonable indicators of feasibility. In addition, patients showed short-term reductions in pain and distress. Next steps include attention to improving staff availability and intervention implementation in order to feasibly evaluate the perioperative YST, which shows promise for reducing postoperative pain and distress.

A randomized trial of yoga for stress and substance use among people living with HIV in reentry

BACKGROUND

People in reentry from prison or jail (returning citizens) living with HIV and substance use problems often experience numerous stressors and are at high risk for resumed substance use. Interventions are needed to manage stress as a pathway to reduced substance use.

OBJECTIVE

This study explored the effect of a hatha yoga intervention as compared to treatment as usual on stress and substance use among returning citizens living with HIV and substance use problems.

METHODS

Participants were randomized to either a 12-session, 90-minute weekly yoga intervention or treatment as usual. All participants were clients of a service provider for returning citizens that offered case management, health care, and educational classes. Outcomes included stress as measured by the Perceived Stress Scale at the completion of the yoga intervention (three-months) and substance use as measured by the Timeline Followback at one-month, two-months, and three-months.

RESULTS

Seventy-five people were enrolled, two of whom were withdrawn from the study because they did not have HIV. Of the 73 remaining participants, 85% participated in the three-month assessment. At three-months, yoga participants reported less stress than participants in treatment as usual [F (1,59) = 9.24, p < .05]. Yoga participants reported less substance use than participants in treatment as usual at one-month, two-months, and three-months [X² (1) = 11.13, p < .001].

CONCLUSION

Yoga interventions for returning citizens living with HIV and substance use problems may reduce stress and substance use. This finding is tentative because the control group did not receive an intervention of equal time and intensity.
