The effectiveness of yoga for depression: a critical literature review

A randomized trial examining the effect of yoga on dietary lapses and lapse triggers following behavioral weight loss treatment

Background

Dietary lapses can hinder weight loss and yoga can improve self-regulation, which may protect against lapses. This study examined the effect of yoga on dietary lapses, potential lapse triggers (e.g., affective states, cravings, dietary temptations), and reasons for initiating eating following weight loss treatment.

Methods

Sixty women with overweight/obesity (34.3 ± 3.9 kg/m2) were randomized to a 12 week yoga intervention (2x/week; YOGA) or contact-matched control (cooking/nutrition classes; CON) following a 12-week behavioral weight loss program. Participants responded to smartphone surveys (5x/day) over a 10-day period at baseline, 12, and 24 weeks to assess lapses and triggers.

Results

At 24 weeks, YOGA and CON differed on several types of lapses (i.e., less eating past full, eating more than usual, loss of control when eating, self-identified overeating, difficulty stopping eating in YOGA), and YOGA was less likely to eat to feel better or in response to stress (ps < 0.05). YOGA also reported less stress and anxiety and more positive affect (ps < 0.01); dietary temptations and cravings did not differ from CON.

Conclusion

Yoga resulted in fewer dietary lapses and improved affect among women with overweight/obesity following weight loss. While preliminary, findings suggest that yoga should be considered as a potential component of weight loss treatment to target dietary lapses.

Efficacy of Eat Breathe Thrive: A randomized controlled trial of a yoga-based program

Evidence positions yoga as a promising intervention for enhancing positive embodiment and supporting the prevention of, and recovery from, eating disorders (EDs) by reducing ED symptomatology and building skills that facilitate an ongoing, embodied sense of wellbeing. However, yoga-based programs are few and rigorous literature on their efficacy is limited. This study examined the efficacy and feasibility of a yoga-based program called Eat Breathe Thrive (EBT) which aims to prevent EDs and support embodiment. Participants (N = 168, 93.5 % women) from a community sample in the United States and United Kingdom, ages 18-65, were randomly allocated to a 2-h, 7-week EBT program or waitlist-control condition. Compared to controls, EBT participants experienced significant decreases in ED behaviors, depression, and difficulties regulating emotions. They reported significantly greater use of mindfulness skills, such as interoceptive awareness, mindful self-care, and mindful eating. After a single session, participants reported immediate improvement in their sense of well-being, indicating increased state positive embodiment. Most effects were sustained at 6-month follow-up. The majority of individuals attended most sessions. Self-reported treatment integrity was excellent. Directions for future research are proposed. Results support the efficacy and feasibility of an integrated yoga intervention that fosters positive ways of inhabiting the body.

Relationship between types of physical activity and depression among 88,522 adults

BACKGROUND

Physical activity is associated with depression; however, the influence of physical activity type on this association remains poorly explored. We aimed to investigate the association between various types of leisure-time physical activity and depression among a large and representative sample.

METHODS

Data from the 2019 Brazilian National Health Survey were used (n = 88,522 adults aged between 18 and 107 years, 53% female). Depression was measured using the Patient Health Questionnaire-9; participants' leisure-time physical activity types were self-reported. A four-step hierarchical regression was applied, and the analyses were adjusted for several confounders.

RESULTS

Active individuals had lower odds of depression (odds ratio [OR], 0.71; 95% confidence interval [CI], 0.62-0.81); however, only outdoor walking/running (OR, 0.70; 95% CI, 0.60-0.82), cycling (OR, 0.50; 95% CI, 0.34-0.74), and team sports (OR, 0.52; 95% CI, 0.42-0.66) were associated with lower odds of depression than inactivity.

CONCLUSIONS

Physical activity type may be associated with mental health. The qualitative mechanisms of some physical activities seem to have greater capability than others to reduce depression. Causal inferences could not be made, however, our findings suggest that specific physical activities types have additional benefits that can be used in promoting mental health in clinical intervention and at a population level.

A qualitative investigation of a prenatal yoga intervention to prevent excessive gestational weight gain: A thematic analysis of interviews

PURPOSE

To describe pregnant women's experiences and perceived facilitators/barriers of a prenatal yoga intervention to prevent excessive gestational weight gain (EGWG).

METHODS

Pregnant women (N = 13) were interviewed after participation in a 12-week prenatal yoga intervention to prevent EGWG. Interviews were summarized using thematic analysis.

RESULTS

Twelve themes were identified and organized into four categories: 1) experiences of prenatal yoga (positive experience/enjoyment, pain relief, connecting to body), 2) prenatal yoga and weight (increased mindfulness/self-awareness, increased physical activity, weight management), 3) barriers to prenatal yoga (physical body, commute/traffic, schedule), and 4) facilitators of prenatal yoga (healthy pregnancy, support from other pregnant women, the feeling from prenatal yoga).

CONCLUSION

Prenatal yoga may relieve pain and help women be more connected to their bodies. Prenatal yoga may also help women become more aware of their health behaviors and increases their physical activity which may have important implications for reducing EGWG.

Use of Complementary Alternative Medicine and the Associated Factors among Patients with Depression

Complementary Alternative Medicine (CAM) has been widely used in the world, but limited data are available on the use of CAM in depression. This study aimed to evaluate the use of CAM and its associated factors in depression. This cross-sectional study was conducted on 300 depressed patients referred to the Yasuj Neurology and Psychiatric Clinic, southern Iran, between 2019 and 2020. A valid semistructured international questionnaire was used; amongst the participants, 230 (77%) were female. The mean age of the patients was 41.47 ± 12.2 years and the mean duration of the disease was 4.49 ± 4.88 years. The prevalence of CAM use was 37.6% among the patients. The results showed a significant difference between the CAM users and nonusers regarding the disease duration (p=0.045) and body mass index (p=0.007). Moreover, the results of logistic regression analysis revealed a significant relationship between CAM use and female gender, disease duration, overweight, obesity, and self-employment (p=0.039, p=0.028, p=0.029, p=0.048, and p=0.044, resp.). The most frequently used type of CAM was herbal medicine (97.35%) followed by pray therapy (23.89%). Additionally, the most widely used herbs were borage (77%), chamomile (46.9%), and lavender (21.2%). Furthermore, 62.8% of the patients reported that their main reason for using CAM was its effectiveness. The majority of the patients (77%) had not consulted their physicians prior to utilization of CAM therapies. Herbal medicine was the most common form of CAM in depression, with a high satisfaction level. Thus, it is necessary to increase physicians' awareness in different fields of CAM.

Caregivers of People With Disabilities: A Program to Enhance Wellness Self-Care

Caregivers are a source of support for family members with disabilities. However, caregivers are at risk for caregiver burden, which can erode self-care skills and lead to poor physical and mental health outcomes. Caregiver Wellness Self-Care, developed to address that risk, is a 5-week group program in which participants learn about strategies that cultivate their inner resources, while connecting with others for support. Wellness, self-care, mindfulness, and yoga-based information and practices are taught in the sessions and included in participant handouts. Self-reflection and planning activities with facilitated discussions further support awareness and personal transformation. Designed by and for people providing care to an adult family member with a mental health disorder and a developmental/intellectual disability, the program was piloted three times. The current article describes the development of the program through caregiver involvement, participant and facilitator feedback, and implications for future efforts to build caregiver wellness self-care skills. Implications for nurses are highlighted. [Journal of Psychosocial Nursing and Mental Health Services, 59(5), 25-32.].

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.

Yoga not a (physical) culture for men? Understanding the barriers for yoga participation among men

Yoga offers an integrated approach to health and well-being that could potentially benefit men. This qualitative descriptive study examined men's perceptions of yoga, and identified barriers and possible facilitators for participation. Twenty-one non-yoga participant men, 18-60 years old, and living in Queensland, Australia, were interviewed. Two major barriers were identified using thematic analysis: (1) preference for other forms of physical activity, and (2) gender-related perceptions and pressures (i.e., perception of yoga as feminine, and presence of "bloke" culture and masculine ideals in society). Potential facilitators included: (1) acceptability of yoga among men, (2) providing brief information sessions, and (3) men-only classes. The non-competitive nature of yoga, in addition to being predominantly undertaken by women, makes it less appealing for men living in Australia. These barriers need to be considered if yoga is to be promoted as an option for men, particularly those not drawn to traditional sports or exercise.

Technological advancements to address elderly loneliness: Practical considerations and community resilience implications for COVID-19 pandemic

PURPOSE

Loneliness has been a known severe public health concern among the elderly population during the COVID-19 pandemic. The aim of this paper is to discuss the practicalities of using emerging technologies to address elderly loneliness and its implications and adaptations to the outbreak of coronavirus disease-2019.

DESIGN/METHODOLOGY/APPROACH

The authors draw on examples from the literature and their own observations from working with older adults, to provide an overview of possible ways technology could help this population in the current COVID-19 pandemic.

FINDINGS

Technological advancements have offered remarkable opportunities to deliver care and maintain connections despite the need to stay physically separated. These tools can be integrated into crisis communications, public health responses, and care programs to address loneliness among the elderly. However, it must be done strategically and informed by the type of loneliness at play, environmental factors, socioeconomics, and technological literacy.

ORIGINALITY

Technological advancements can be a valuable tool in addressing known public health concerns, such as loneliness among the elderly populations. However, the use of this tool should be governed by the specific situation at hand, taking into consideration individual needs and environmental factors, especially the compounded effects caused by the coronavirus pandemic. Different technological programs and approaches are appropriate for different types of loneliness. For example, online therapy such as internet-based cognitive behavior therapy may mitigate loneliness caused by fear; online interaction such as videoconferencing may relieve loneliness caused by lack of social engagement.

PRACTICAL IMPLICATIONS

Care-providing organizations and policy makers should consider the risk of loneliness while responding to COVID-19 outbreak, particularly within elderly populations. As part of a broader plan, technological solutions as well as low-tech approaches can make a difference in mitigating loneliness. Solutions should be accessible to and usable by older adults. Provision of equipment, training, and guidance may be necessary to execute a technology-centric plan; for some communities and individuals, approaches that do not rely on advanced technology may be more effective.

Amigas Latinas Motivando el Alma (ALMA): an Evaluation of a Mindfulness Intervention to Promote Mental Health among Latina Immigrant Mothers

Latina immigrants are at increased risk for poor mental health. Amigas Latinas Motivando el Alma (ALMA) is a group-based intervention to reduce symptoms of depression, anxiety, and stress among Latina immigrants. Based on participants' feedback and growing evidence supporting mindfulness as a way to reduce stress and improve mental health, additional sessions of the ALMA intervention were developed and pilot tested to provide more training on mindfulness as a coping strategy. The feasibility and potential efficacy were evaluated in a community sample using a pre- and post-test study design. Findings suggested that women were satisfied with the sessions and used mindfulness strategies they learned in their daily lives. The program also reduced symptoms of depression and anxiety (19% reduction in mean depression scores and 26% reduction in mean anxiety scores). Further evaluation is needed to test the efficacy of the intervention.

Effect of Sudarshan Kriya Yoga on anxiety, depression, and quality of life in people with type 2 diabetes: A pilot study in Kuwait

AIM

This pilot study in Kuwait was aimed to assess the effect of Sudarshan kriya yoga (SKY) on anxiety, depression and total quality of life in people with type 2 diabetes mellitus (T2DM).

METHODS

26 T2DM patients aged greater than 30, male and female visiting the outpatient clinic of Dasman Diabetes Institute were enrolled for the study. Pre and post 5 day SKY intervention responses of participants on psychosocial problems were evaluated using four questionnaires (Hamilton anxiety, patient health questionnaire (PHQ-9), Hospital anxiety depression and WHO total quality of life (QOL). Biochemical parameters; such as lipid profile, glycated hemoglobin (HbA1c) were measured at baseline and after 15 weeks of SKY practice.

RESULTS

The mean age of the participants was 56.7 (±11.4 SD) years, and mean duration of diabetes 15.0 (±9.3 SD) years. Comparison of responses before and after intervention indicated a significant improvement in the QOL, depression, anxiety and insomnia. But no significant improvement in glycemic control.

CONCLUSION

Results indicate that SKY can be potentially beneficial for treating anxiety, insomnia, and depression associated in people with T2DM and in improving the quality of life in people with T2DM.

The experience of mindful yoga for older adults with depression

WHAT IS KNOWN ON THE SUBJECT?: Mindful yoga combines yoga techniques with the mindfulness-based stress reduction approach. Previous studies on mindful yoga have reported improvements in depression for working-age adults, but no studies have been conducted with older people. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: Mindful yoga may be a safe and acceptable intervention to improve the mental and physical health of older adults with depression. The beneficial therapeutic ingredients of mindful yoga, included calmness, being non-judgmental, letting go and seizing the day. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Single-sex mindful yoga groups may be more acceptable for some people. Well-conducted feasibility studies comparing mindful yoga with an alternative group-based approach are necessary. Abstract Introduction Mindful yoga combines yoga techniques with the mindfulness-based stress reduction approach. Previous studies on mindful yoga have reported improvements in depression for working-age adults, but no studies have been conducted with older people. Aims To explore the experiences of older adults with depression participating in a mindful yoga group to establish whether the approach has potential as a future intervention for this client group. Method This study adopted a qualitative descriptive method and used inductive content analysis. Eighteen in-depth individual interviews were conducted with nine participants (each participant had one interview following the programme and another four weeks later). Results Six main themes emerged: "improved physical status," "actively involved in the community," "positive psychological effects," "perceived therapeutic ingredients," "facilitators of practising mindful yoga" and "barriers to practising mindful yoga.". Discussion Most participants reported benefitting from the programme. Two male participants expressed that exercises were too challenging and more suited to women, suggesting single-sex groups may be more acceptable. Implications for practice Mindful yoga may be an acceptable/useful intervention for older adults with depression, but future studies are required to establish its feasibility and potential efficacy.

Yoga's Biophysiological Effects on Lower Urinary Tract Symptoms: A Scoping Review

BACKGROUND AND OBJECTIVES

Yoga is a mind and body practice that includes relaxation, meditation, breathing exercises, and body postures. It can be effective in enhancing the functioning of several body systems, including the lower urinary tract. Normal lower urinary tract functioning depends in part on the coordination of the bladder, urethra, pelvic floor and other muscles, and the nerves that control them. Lower urinary tract dysfunction can lead to symptoms, that is, stress urinary incontinence (UI), urinary frequency, nocturia, urinary urgency with and without incontinence, and mixed UI. Recent evidence suggests that yoga can improve lower urinary tract symptoms (LUTS). Thus, we performed a scoping review of the literature with regard to the evidence for the effects of yoga on LUTS and factors that may mediate yoga's effects on LUTS with the goal to identify gaps in knowledge regarding the relationship between yoga practice and LUTS.

METHODS

The authors employed the PRISMA extension for Scoping Reviews (PRISMA-ScR) methodological approach, proposed by Tricco et al., by searching the electronic databases, PubMed, Embase, and PsycINFO, for articles using the following keywords: yoga, urinary incontinence, urinary tract, bladder, and urethra. We assessed the quality of the studies using the Joanna Briggs Institute Critical Appraisal Checklist.

RESULTS

Of the 172 articles we found, 8 articles met the inclusion criteria and were reviewed. We found that, despite the use of different protocols, yoga may reduce certain LUTS by increasing the strength of pelvic floor muscle and/or regulating the autonomic nervous system and activating the central nervous system.

CONCLUSIONS

Yoga is a noninvasive practice that may improve some LUTS. Rigorous studies are needed to determine the specific mechanisms through which yoga may affect LUTS.

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.

The burden of depressive disorders in South Asia, 1990-2016: findings from the global burden of disease study

BACKGROUND

Globally, depressive disorders are one of the most common forms of mental illness. Using data from the most recent Global Burden of Disease, Injury, and Risk Factor Study 2016 (GBD 2016), we aimed to describe the burden of disease attributable to depressive disorders in terms of prevalence and disability-adjusted life years (DALYs) in South Asia countries (namely India, Pakistan, Bangladesh, Nepal and Bhutan).

METHODS

GBD 2016 used epidemiological data on depressive disorders (major depression and dysthymia) from South Asia and a Bayesian meta-regression tool (DisMod-MR 2.1) to model prevalence and DALYs of depressive disorders by age, sex, country and year. DALYs were calculated from the years lived with disability (YLDs), derived from the prevalence of depressive disorders and disability weights, obtained from a community and internet-based surveys. The analyses adjusted for comorbidity, data sources and multiple modelling, and estimates were presented with 95% uncertainty intervals (UI).

RESULTS

In 2016, the age-standardised prevalence of depressive disorders in South Asia was 3.9% (95% UI: 3.6-4.2%), 4.4% (95% UI: 4.4-4.8%) in Bangladesh, 3.9% (95% UI: 3.6-4.2%) in India, 3.0% (95% UI: 2.8-3.3%) in Pakistan, 4.0% (95% UI: 3.7-4.3%) in Nepal and 3.7% (95% UI: 3.4-4.1%) in Bhutan. In South Asia, depressive disorders accounted for 9.8 million DALYs (95% UI: 6.8-13.2 million) or 577.8 (95% UI: 399.9-778.9) per 100,000 population in 2016. Of these, major depressive disorders (MDD) accounted for 7.8 million DALYs (95% UI: 5.3-10.5 million). India generated the largest numbers of DALYs due to depressive disorders and MDD, followed by Bangladesh and Pakistan. DALYs due to depressive disorders were highest in females and older adults (75-79 years) across all countries.

CONCLUSION

Our findings show the substantial public health burden of depressive disorders in South Asian populations and healthcare systems. Given the scale of depressive disorders, improvement in overall population health is possible if South Asian countries prioritise the prevention and treatment of depressive disorders.

Modern postural yoga as a mental health promoting tool: A systematic review

Yoga has been gaining popularity as a complementary therapy for mental health conditions, but research on the efficacy of yoga is still in its beginnings. The aim of this systematic review is to investigate the effects of modern postural yoga (strong focus on physical postures) on positive mental health (PMH) indicators in clinical and nonclinical populations. The most common PMH indicators were mindfulness, affect, resilience and well-being, followed by satisfaction with life, self-compassion, empathy and others. Diverse results were found across the 14 studies analysed, including significant positive effects of yoga practice on outcome variables, to no significant effects, both in relation to baseline levels and in relation to control groups. Nonetheless, most studies observed ameliorations in PMH indicators due to yoga practice. Given that yoga interventions pose serious methodological concerns, more research and better experimental designs are needed to properly assess the effects of yoga on PMH indicators.

The physical postures of yoga practices may protect against depressive symptoms, even as life stressors increase: a moderation analysis

Yoga contains sub-components related to its physical postures (asana), breathing methods (pranayama), and meditation (dhyana). To test the hypothesis that specific yoga practices are associated with reduced psychological distress, 186 adults completed questionnaires assessing life stressors, symptom severity, and experience with each of these aspects of yoga. Each yoga sub-component was found to be negatively correlated with psychological distress indices. However, differing patterns of relationship to psychological distress symptoms were found for each yoga sub-component. Experience with asana was negatively correlated with global psychological distress (r = -.21, p < .01), and symptoms of anxiety (r = -.18, p = .01) and depression (r = -.17, p = .02). These relationships remained statistically significant after accounting for variance attributable to Social Readjustment Rating Scale scores (GSI: r = -.19, p = .01; BSI Anxiety: r = -.16, p = .04; BSI Depression: r = -.14, p = .05). By contrast, the correlations between other yoga sub-components and symptom subscales became non-significant after accounting for exposure to life stressors. Moreover, stressful life events moderated the predictive relationship between amount of asana experience and depressive symptoms. Asana was not related to depressive symptoms at low levels of life stressors, but became associated at mean (t[182] = -2.73, p < .01) and high levels (t[182] = -3.56, p < .001). Findings suggest asana may possess depressive symptom reduction benefits, particularly as life stressors increase. Additional research is needed to differentiate whether asana has an effect on psychological distress, and to better understand potential psychophysiological mechanisms of action.

A single session of hatha yoga improves stress reactivity and recovery after an acute psychological stress task-A counterbalanced, randomized-crossover trial in healthy individuals

OBJECTIVES

Yoga is promoted as an anti-stress activity, however, little is known about the mechanisms through which it acts. The present study investigated the acute effects of a hatha yoga session, displayed on a video, on the response to and recovery from an acute psychological stressor.

METHODS

Twenty-four healthy young adults took part in a counterbalanced, randomized-crossover trial, with a yoga and a control condition (watching TV). Participants attended the laboratory in the afternoon on two days and each session comprised a baseline, control or yoga task, stress task and recovery. Blood pressure (BP), heart rate (HR) and salivary cortisol responses were measured. State cognitive- and somatic-anxiety along with self-confidence were assessed before and after the stressor.

RESULTS

Although no difference in the BP or HR responses to stress were found between conditions, systolic BP (p=0.047) and diastolic BP (p=0.018) recovery from stress were significantly accelerated and salivary cortisol reactivity was significantly lower (p=0.01) in the yoga condition. A yoga session also increased self-confidence (p=0.006) in preparation for the task and after completion. Moreover, self-confidence reported after the stress task was considered debilitative towards performance in the control condition, but remained facilitative in the yoga condition.

CONCLUSION

Our results show that a single video-instructed session of hatha yoga was able to improve stress reactivity and recovery from an acute stress task in healthy individuals. These positive preliminary findings encourage further investigation in at-risk populations in which the magnitude of effects may be greater, and support the use of yoga for stress reactivity and recovery.

Psychosocial predictors of gestational weight gain and the role of mindfulness

OBJECTIVE

To identify the psychosocial factors (i.e., stress, anxiety, depression, social support) that are associated with gestational weight gain (GWG) and the relationship of mindfulness with GWG during each trimester of pregnancy.

DESIGN

In this cross-sectional study, an online survey that assessed physical and mental health and wellness practices was administered to pregnant women.

PARTICIPANTS

Pregnant women ≥8 weeks gestation, ≥18 years old, and could read and write in English.

MEASUREMENT AND FINDINGS

Women who responded to the survey (N=1,073) were on average 28.7±4.6 years old. Findings from a regression analysis suggest that increased levels of depression may be predictive of increased GWG in the second trimester and decreased levels of mindfulness may be predictive of increased GWG in the first trimester. Anxiety, stress, and overall social support were not associated with GWG in any trimester.

KEY CONCLUSIONS

Mindfulness-based strategies (e.g., yoga) may have the potential to manage both depression and excessive GWG and may beneficial for and preferred by pregnant women. More research is warranted to determine clear relationships between psychosocial health, mindfulness, and GWG.

IMPLICATIONS FOR PRACTICE

Health care providers are encouraged to screen for depression in early pregnancy (i.e., first or second trimester) and provide resources to manage symptoms of depression and GWG to promote optimal birth outcomes. Health care providers may want to counsel patients on how to manage depression and/or GWG by suggesting mindfulness-based approaches.

Perceptions, Uses of, and Interests in Complementary Health Care Approaches in Depressed Pregnant Women: The PAW Survey

Depression affects up to 23% of pregnant women and is associated with adverse physical/mental health outcomes for both the mother and baby. Depressed pregnant women may be more likely to engage in unhealthy lifestyle behaviors that contribute to an increased risk for chronic disease. Little is known regarding depressed pregnant women's perceptions, uses of, and interests in complementary health approaches. Study participants (mean age 28.7 ± 6.8; n = 1032) included pregnant women ≥8 weeks gestation who responded to a survey assessing physical and mental health and wellness practices. Of those completing the survey, depressed pregnant women (n = 272) had significantly higher levels of anxiety (P < .001) and stress (P < .001) and had poorer sleep quality (P < .001), mindfulness (P < .001), and social support (P < .001) compared to nondepressed pregnant women (n = 760). A majority (84%) of depressed pregnant women would consider using a complementary health approach for weight and/or stress management during pregnancy, and more than 50% were interested in yoga.

Yoga as palliation in women with advanced cancer: a pilot study

OBJECTIVE

The purpose of this pilot study was to investigate the palliative potential of home-based yoga sessions provided to women with advanced cancer.

METHOD

Personalised 45-minute yoga sessions were offered to three women with advanced cancer by an experienced yoga teacher. Each woman took part in a one-to-one interview after the completion of the yoga programme and was asked to describe her experiences of the programme's impact.

RESULTS

The personalised nature of the yoga sessions resulted in similar positive physical and psychosocial effects comparable to those demonstrated in other studies with cancer patients. Participants described physical, mental, and emotional benefits as well as the alleviation of illness impacts. The enhancement of mind-body and body-spirit connections were also noted.

CONCLUSION

Personalised home-based yoga programmes for people with advanced cancer may produce similar benefits, including palliation, as those institutionally-based programmes for people with non-advanced cancer.

The Essential Properties of Yoga Questionnaire: Development and Methods

Yoga interventions have considerable heterogeneity, are multi-dimensional, and may impact health in different ways. However, most research reports regarding the effects of yoga on health and wellbeing do not adequately describe the components of the yoga interventions being used. Thus, drawing comparisons across studies or understanding the relative effects of specific aspects of a yoga intervention are rarely possible. To address this problem, we created the Essential Properties of Yoga Questionnaire (EPYQ) Project, an NCCAM-funded set of studies to develop a translational tool for yoga researchers. Here we describe the methods and developmental processes used in the EPYQ Project in detail. The project consists of four main phases. Phase I was designed to gain a comprehensive understanding of the relevant aspects of yoga by conducting a comprehensive systematic literature review and conducting focus groups with stakeholders including a wide variety of yoga teachers and students. In Phase II, a pool of potential questionnaire items was developed for the prototypic questionnaire using information from Phase I. Cognitive interviews were conducted with the preliminary EPYQ items to assess the perceived clarity, meaning, and importance of each item. In Phase III, the prototypic questionnaire was administered to two large samples of yoga students and instructors. Military personnel and veterans who practiced or taught yoga (n = 329) were recruited to participate. Factor analysis and item response theory were used to identify factors and select the final questionnaire items. Phase IV is ongoing and will collect reliability and validity data on the final instrument. Results are expected to be available in 2016. The EPYQ will provide an objective tool for describing the amount of various components of yoga interventions, eventually allowing researchers to link specific yoga components to health benefits, and facilitating the design of yoga interventions for specific health conditions.

Effects of Yoga on Stress, Stress Adaption, and Heart Rate Variability Among Mental Health Professionals--A Randomized Controlled Trial

BACKGROUND

Mental health professionals experiencing work-related stress may experience burn out, leading to a negative impact on their organization and patients.

AIM

The aim of this study was to examine the effects of yoga classes on work-related stress, stress adaptation, and autonomic nerve activity among mental health professionals.

METHODS

A randomized controlled trial was used, which compared the outcomes between the experimental (e.g., yoga program) and the control groups (e.g., no yoga exercise) for 12 weeks. Work-related stress and stress adaptation were assessed before and after the program. Heart rate variability (HRV) was measured at baseline, midpoint through the weekly yoga classes (6 weeks), and postintervention (after 12 weeks of yoga classes).

RESULTS

The results showed that the mental health professionals in the yoga group experienced a significant reduction in work-related stress (t = -6.225, p < .001), and a significant enhancement of stress adaptation (t = 2.128, p = .042). Participants in the control group revealed no significant changes. Comparing the mean differences in pre- and posttest scores between yoga and control groups, we found the yoga group significantly decreased work-related stress (t = -3.216, p = .002), but there was no significant change in stress adaptation (p = .084). While controlling for the pretest scores of work-related stress, participants in yoga, but not the control group, revealed a significant increase in autonomic nerve activity at midpoint (6 weeks) test (t = -2.799, p = .007), and at posttest (12 weeks; t = -2.099, p = .040).

LINKING EVIDENCE TO ACTION

Because mental health professionals experienced a reduction in work-related stress and an increase in autonomic nerve activity in a weekly yoga program for 12 weeks, clinicians, administrators, and educators should offer yoga classes as a strategy to help health professionals reduce their work-related stress and balance autonomic nerve activities.
