Framingham Risk Score and Estimated 10-Year Cardiovascular Disease Risk Reduction by a Short-Term Yoga-Based LifeStyle Intervention

The aim of this study was to evaluate the efficacy of a short-term yoga-based lifestyle intervention program in lowering Framingham Risk Score (FRS) and estimated 10-year cardiovascular risk. This was a single-arm, pre-post interventional study including data from a historical cohort with low to moderate risk for cardiovascular disease (CVD). It was conducted in a tertiary-care hospital. Participants with low (0 or 1 CVD risk factors) to moderately high risk (10-year risk between 10% and 20% and two or more CVD risk factors) were included. Participants with previously diagnosed CVD, defined as a history of myocardial infarction, congestive heart failure, or cerebrovascular accident, were excluded from the analysis. However, those with controlled hypertension were included. Intervention included a pretested short-term yoga-based lifestyle intervention, which included asanas (physical postures), pranayama (breathing exercises), meditation, relaxation techniques, stress management, group support, nutrition awareness program, and individualized advice. The intervention was for 10 days, spread over 2 weeks. However, participants were encouraged to include it in their day-to-day life. Outcomes included changes in FRS, and estimated 10-year CVD risk from baseline to week 2. A gender-based subgroup analysis was also done, and correlation between changes in FRS and cardiovascular risk factors was evaluated. Data for 554 subjects were screened, and 386 subjects (252 females) were included in the analysis. There was a significant reduction in FRS (p < 0.001) and estimated 10-year cardiovascular risk (p < 0.001) following the short-term yoga-based intervention. There was a strong positive correlation between reduction in FRS and serum total cholesterol (r = 0.60; p < 0.001). There was a moderate positive correlation between reduction in FRS and low-density lipoprotein cholesterol (r = 0.58; p < 0.001), and a weak but positive correlation between reduction in FRS and triglycerides (r = 0.26; p ≤ 0.001), serum very-low-density lipoprotein cholesterol (r = 0.29; p < 0.001), and systolic blood pressure (r = 0.20; p ≤ 0.001). This yoga-based lifestyle intervention program significantly reduced the CVD risk, as shown by lowered FRS and estimated 10-year CVD risk. Further testing of this promising intervention is warranted in the long term.

ICF-based improvements in body structures and function, and activity and participation in chronic stroke following a yoga-based intervention

Purpose: The purpose of this study was to understand the perceived outcomes following a yoga intervention for individuals with chronic stroke, framed within the context of the International Classification of Functioning, Disability, and Health.Method: Twenty-six individuals with chronic stroke participated in one of five focus groups immediately following completion of an 8-week yoga intervention.Results: Primary themes emerged related to body structure and function (with subthemes of improved emotional regulation, increased stability and range of motion, and unexpected improvements in body function), and improvements in activity and participation. The improvements in body function led to participants more fully participating in their lives.Conclusions: While rehabilitation is not typically offered in the chronic poststroke period, the participants in this yoga study perceived changes in body functions, activity, and participation that they associated with the yoga intervention. Larger studies need to quantify these changes to make specific policy recommendations.

Using Yoga to Reduce Stress and Bullying Behaviors among Urban Youth

Background/Purpose: Obesity and secondary conditions continue to disproportionally affect the health of children living in urban areas. Studies show that a lack of resources and physical activity-unfriendly communities discourage 60 minutes of daily activity, including strengthening exercises, as recommended by the Centers for Disease Control and Prevention. Using Social Ecological theory, the purpose of this study was to examine the multi-level influences of a yoga-based intervention on urban, inner city youth. Method: Using a mixed-methods design, ninety-three 3 - 5th grade students at five urban elementary schools participated in a ten-week yoga intervention. Analysis/Results: RM-ANOVA results revealed a significant reduction in stress and bullying behaviors among participants, and multiple regression analyses revealed that program attendance, change in stress, and change in yoga enjoyment significantly predicted change in yoga participation outside PE, when controlling for gender and age F(5, 87) = 5.36, p R2 = 0.19, but did not have a significant impact on physical activity participation outside of school. Student interviews and non-participant observations revealed strong enjoyment of yoga which led students to report substantial increases in yoga-related activities outside of school. Students also revealed that experience in yoga improved focus, attention, and reduced stress. Conclusions: Through convergence of qualitative and quantitative methods, this study showed a positive relationship between the number of yoga sessions attended (dose), enjoyment of yoga, and participation in yoga outside PE with friends and family. Findings suggest that urban PE should include more individual, non-competitive activities such as yoga, which students find to be stress-relieving, fun, inexpensive and easy to perform at home.

Influence of Yoga-Based Personality Development Program on Psychomotor Performance and Self-efficacy in School Children.

Selective attention and efficacy are important components of scholastic performance in school children. While attempts are being made to introduce new methods to improve academic performance either as part of curricular or extracurricular activities in schools, the success rates are minimal. Hence, this study assessed the effect of yoga-based intervention on psychomotor performance and self-efficacy in school children. Two hundred ten school children with ages ranging from 11 to 16 years (mean age ± SD; 13.7 ± 0.8 years) satisfying the inclusion and exclusion criteria were recruited for the 10-day yogä program. An equal number of age-matched participants (n = 210; mean ± SD; 13.1 ± 0.8 years) were selected for the control group. Participants were assessed for attention and performance at the beginning and end of 10 days using trail making task (TMT) A and B, and self-efficacy questionnaire. The yoga group showed higher self-efficacy and improved performance after 10 days of yoga intervention. The performance in TMT-A and -B of the yoga group showed a significantly higher number of attempts with a reduction in time taken to complete the task and a number of wrong attempts compared with control group. Results suggest that yoga practice enhances self-efficacy and processing speed with fine motor coordination, visual–motor integration, visual perception, planning ability, and cognitive performance.

Yoga-based intervention in patients with somatoform disorders: an open label trial

Somatoform disorders are common mental disorders associated with impaired functioning and increased utilization of health resources. Yoga-based interventions have been used successfully for anxiety, depression, and chronic pain conditions. However, literature on the use of yoga in treatment of somatoform disorders is minimal. The current study assessed the effect of a specific yoga-based intervention in patients with somatoform disorders. Consenting patients meeting ICD-10 criteria for somatoform disorders were offered a specific yoga module (1 h per day) as a treatment. Assessments including Visual Analogue Scale (VAS), Brief Pain Inventory (BPI), and others were carried out at baseline and after 2, 6, and 12 weeks. Sixty-four subjects were included in the study and 34 completed 12 weeks follow-up. Significant improvement was noted in pain severity from baseline to 12 weeks after regular yoga sessions. The mean VAS score dropped from 7.24 to 2.88. Worst and average pain score in the last 24 h on BPI dropped from 7.71 to 3.26 and from 6.12 to 2.0,7 respectively. Results of the study suggest that yoga-based intervention can be one of the non-pharmacological treatment options in somatoform disorders. These preliminary findings need replication in larger controlled studies.

Designing and validation of a yoga-based intervention for obsessive compulsive disorder

Some yoga-based practices have been found to be useful for patients with obsessive compulsive disorder (OCD). The authors could not find a validated yoga therapy module available for OCD. This study attempted to formulate a generic yoga-based intervention module for OCD. A yoga module was designed based on traditional and contemporary yoga literature. The module was sent to 10 yoga experts for content validation. The experts rated the usefulness of the practices on a scale of 1–5 (5 = extremely useful). The final version of the module was pilot-tested on patients with OCD (n = 17) for both feasibility and effect on symptoms. Eighty-eight per cent (22 out of 25) of the items in the initial module were retained, with modifications in the module as suggested by the experts along with patients’ inputs and authors’ experience. The module was found to be feasible and showed an improvement in symptoms of OCD on total Yale-Brown Obsessive-Compulsive Scale (YBOCS) score (p = 0.001). A generic yoga therapy module for OCD was validated by experts in the field and found feasible to practice in patients. A decrease in the symptom scores was also found following yoga practice of 2 weeks. Further clinical validation is warranted to confirm efficacy.

Designing and validation of a yoga-based intervention for schizophrenia

Context: Schizophrenia is a chronic mental illness which causes significant distress and dysfunction. Yoga has been found to be effective as an add-on therapy in schizophrenia. Modules of yoga used in previous studies were based on individual researcher’s experience.Aim: This study aimed to develop and validate a specific generic yoga-based intervention module for patients with schizophrenia. The study was conducted at NIMHANS Integrated Centre for Yoga (NICY).Materials and methods: A yoga module was designed based on traditional and contemporary yoga literature as well as published studies. The yoga module along with three case vignettes of adult patients with schizophrenia was sent to 10 yoga experts for their validation.Results: Experts (n = 10) gave their opinion on the usefulness of a yoga module for patients with schizophrenia with some modifications. In total, 87% (13 of 15 items) of the items in the initial module were retained, with modification in the remainder as suggested by the experts.Conclusion: A specific yoga-based module for schizophrenia was designed and validated by experts. Further studies are needed to confirm efficacy and clinical utility of the module. Additional clinical validation is suggested.

Yoga for schizophrenia: Patients' perspective.

Context:Yoga-based intervention is emerging as an effective add-on therapy in the management of schizophrenia. However, many barriers make it difficult for patients to avail yoga therapy programs. One of them is motivation for yoga therapy. Ways to address the barriers are critical to employ yoga as a treatment in this population.Aim:This study aims at exploring patients’ willingness to participate in add-on yoga therapy programs on out-patient basis.Settings and Design:The study was conducted on 100 schizophrenia patients attending psychiatry out-patient services of a tertiary care hospital.Materials and Methods:A total of 100 schizophrenia patients (male: female = 57:43; age: 35.8 ± 9.2 years) attending the psychiatry out-patient services of a tertiary neuropsychiatry hospital were administered a survey questionnaire.Statistical Analysis Used:Chi-square test was used for testing the significance of proportions. P < 0.05 was taken to be significant.Results:About 46% were aware that yoga is also one of the complementary therapies useful in schizophrenia. 32% had tried yoga in the past for some reasons, but only 31% of them were continuing yoga; commonest reasons for not continuing being lack of motivation (31%) and inability to spare time (27.6%). However, the majority (88.5%) of them were willing to take up add-on yoga therapy on out-patient basis along with their regular medical follow-up.Conclusions:In spite of the lack of motivation to practice yoga, the majority of patients were willing to participate in add-on yoga therapy programs if given on out-patient basis along with their regular conventional medical follow-up.

Is job anxiety and perceived stress modifiable in Indian IT professionals? An experimental study using yoga-based intervention

Background: Indian information technology (IT) professionals are continuously subjected to project assignment changes as well as uncertainties in existing project continuations as cancelling of projects is not uncommon. There are periods in the work life of an Indian IT professional when he/she has to cope with no project situation, before being assigned to another project. IT professionals also need to continuously upgrade their IT-relevant skills in order to deliver projects to customers with less capital. All this adds up to job anxiety and perceived stress among IT professionals. With prolonged states of job anxiety and perceived stress, these professionals may become victims of diseases driven by anxiety and stress. There is a popular perception that Yoga, an Indian ancient science, can give control over modifications of mind and hence can help reduce anxiety and stress. Objective: To study the effect of cyclic meditation ( a yoga based practice) on job Anxiety and perceived stress of Indian IT Professionals. Materials and Methods: A control study was carried out on 96 Indian age ranged from 24 to 50 IT Professionals working in Bengaluru, Karnataka, India. Pre-post design was chosen and questionnaire method of collecting data was adopted. Results: The results indicates that after a period of 8 week intervention, there is a reduction of 19.51% in job anxiety and a reduction of 34.77% in perceived stress among Indian IT Professionals. Conclusion: This study indicates that Yoga based practices help to greatly reduce Job Anxiety and Perceived stress among Indian IT professionals. This study also highlights the need to explore the role of Yoga based practices on Indian IT professionals work life in greater detail.

Effect of Yoga-Based Intervention in Patients with Inflammatory Bowel Disease.

Inflammatory bowel disease (IBD) is a chronic illness characterized by gross inflammation in the gastrointestinal tract that can result in symptoms such as abdominal pain, cramping, diarrhea, and bloody stools. IBD is believed to be influenced by psychological factors such as stress and anxiety. Therefore, a yoga intervention that reduces stress and anxiety may be an effective complementary treatment for these disorders. A total of 100 IBD patients [ulcerative colitis (UC) n = 60 and Crohn's disease (CD) n = 40] during the clinical remission phase of disease were included in the study. These patients were allocated randomly to either the yoga group that underwent an 8-week yoga intervention (physical postures, pranayama, and meditation) 1- hour/day in addition to standard medical therapy (UC, n = 30; CD, n = 20) or the control group (UC, n = 30; CD n = 20), which continued with standard medical therapy alone. The main outcome measures were cardiovascular autonomic functions, serum eosinophilic cationic protein, interleukin- 2 soluble receptors, Speilberger's State Trait Anxiety Inventory (STAI) scores, and clinical symptoms. Before the intervention, all the outcome measures were comparable in the two groups. After the 8-week yoga intervention, fewer UC patients reported arthralgia. The number of patients reporting intestinal colic pain in the control group was higher. State and trait anxiety levels were significantly reduced in patients with UC. However, no significant changes were observed in cardiovascular autonomic functions, eosinophilic cationic proteins, or interleukin-2 soluble receptors. A simplified yoga-based regimen is a safe and effective complementary clinical treatment modality for patients with inflammatory bowel disease during the clinical remission phase.

High-density lipoprotein cholesterol increases following a short-term yoga-based lifestyle intervention: a non-pharmacological modulation

Objectives The objective of the study was to assess the effect of a brief but comprehensive yoga-based lifestyle intervention on highdensity lipoprotein cholesterol (HDL-c).Methods This prospective interventional study was performed at the Integral Health Clinic (IHC), an outpatient facility at All India Institute of Medical Sciences, New Delhi, a tertiary health care centre, conducting yoga-based lifestyle intervention programmes for prevention and management of chronic diseases. The study included apparently healthy normal weight, overweight and obese subjects who underwent a pretested 10-day yoga-based programme including asanas (postures), pranayama (breathing exercises), meditation, group discussions, lectures and individualized advice on stress management and healthy diet. The primary outcome measure was change in serum HDL-c at day 10 versus day 0.Results 238 participants (147 women, 91 men, 38.81 ± 11.40 years) were included in the study. There was a significant increase in HDL-c levels from baseline to day 10 (42.93 ± 5.00 vs 43.52 ± 5.07 mg/dL, P = 0.043). Notably, HDL-c was significantly improved in those for whom the baseline HDL-c levels were lower than the recommended values. Also, there was a reduction in blood pressure, fasting blood glucose, and improvement in other lipid profi le variables.Conclusion This yoga-based lifestyle intervention significantly increased HDL-c levels in a short duration of 10 days. This has additional clinical relevance as HDL-c is suggested to be one of the strongest statistically independent predictors of major cardiovascular events.

Improvements in ICF Components in Individuals With Chronic Stroke Following a Yoga-Based Intervention

Objective: To understand perceived outcomes following a yoga intervention for individuals with chronic stroke, framed within the context of the International Classification of Functioning, Disability, and Health. Design: Small, prospective mixed-method, randomized controlled trial of a yoga intervention for individuals at least 6 months post-stroke. Setting: Community-based rehabilitation laboratory. Participants: Forty-seven individuals were randomized to either the intervention or the wait-list control. Twenty-six individuals from the yoga arm agreed to participate in the focus groups. Individuals were eligible for the study if they were >6 months post-stroke and had completed all stroke related rehabilitation. Interventions: The yoga-based intervention was one-hour, twice per week, for a total of 16 yoga classes. Main Outcome Measure(s): Five focus groups occurred during the final week of the yoga intervention. A semi-structured focus group guideline was developed to include questions and probes. Data were analyzed using interpretative phenomenological analysis. Results: Two main themes emerged around domains of the ICF: improvements in body structures and functions; and improvements in activity and participation. In terms of body structure and functions, many study participants discussed substantial perceived changes in both mental and physical functioning, including improved emotional regulation, improvements in stability and range of motion, and unanticipated improvements, such as increases in vision, increased sensation perception, and reduction of diabetic complications. Many study participants commented on the benefits and increases in various activities and participation due to their involvement in the post-stroke yoga intervention. Conclusions: Qualitative data indicated that changes in body function allowed for improved activity and participation.

Designing, validation and feasibility of a yoga-based intervention for elderly

Context:Ageing is an unavoidable facet of life. Yogic practices have been reported to promote healthy aging. Previous studies have used either yoga therapy interventions derived from a particular school of yoga or have tested specific yogic practices like meditation.Aims:This study reports the development, validation and feasibility of a yoga-based intervention for elderly with or without mild cognitive impairment.Settings and Design:The study was conducted at the Advanced Centre for Yoga, National Institute for Mental Health and Neurosciences, Bangalore. The module was developed, validated, and then pilot-tested on volunteers.Materials and Methods:The first part of the study consisted of designing of a yoga module based on traditional and contemporary yogic literature. This yoga module along with the three case vignettes of elderly with cognitive impairment were sent to 10 yoga experts to help develop the intended yoga-based intervention. In the second part, the feasibility of the developed yoga-based intervention was tested.Results:Experts (n=10) opined the yoga-based intervention will be useful in improving cognition in elderly, but with some modifications. Frequent supervised yoga sessions, regular follow-ups, addition/deletion/modifications of yoga postures were some of the suggestions. Ten elderly consented and eight completed the pilot testing of the intervention. All of them were able to perform most of the Sukṣmavyayāma, Prāṇāyāma and Nādānusaṇdhāna (meditation) technique without difficulty. Some of the participants (n=3) experienced difficulty in performing postures seated on the ground. Most of the older adults experienced difficulty in remembering and completing entire sequence of yoga-based intervention independently.Conclusions:The yoga based intervention is feasible in the elderly with cognitive impairment. Testing with a larger sample of older adults is warranted.

Randomized clinical trial of yoga-based intervention in residents from elderly homes: Effects on cognitive function

Context:Elderly have increased risk for cognitive impairment and dementia. Yoga therapy may be helpful in elderly to improve cognitive function.Aims:We examined the benefits of yoga-based intervention compared with waitlist control group on cognitive function in the residents of elderly homes.Settings and Design:Single blind controlled study with block randomization of elderly homes.Materials and Methods:Study sample included yoga group (n=62) and waitlist group (n=58). A total of 87 subjects (yoga=44, waitlist=43) completed the study period of 6 months. Yoga group received daily yoga sessions for 1 month, weekly until 3rd month and encouraged to continue unsupervised until 6 months. They were assessed on Rey's Auditory Verbal Learning Test (RAVLT), Rey's complex figure test (CFT), Wechsler's Memory Scale (WMS)-digit and spatial span, Controlled Oral Word Association (COWA) test, Stroop Color Word Interference Test and Trail Making Test A and B at baseline and at the end of 6th month.Statistical Analysis:Paired t-test and analysis of covariance (ANCOVA) to compare the difference in neuropsychological test scores.Results:Yoga group showed significant improvement in immediate and delayed recall of verbal (RAVLT) and visual memory (CFT), attention and working memory (WMS-spatial span), verbal fluency (COWA), executive function (Stroop interference) and processing speed (Trail Making Test-A) than waitlist group at the end of 6 months after correcting for corresponding baseline score and education.Conclusion:Yoga based-intervention appears beneficial to improve several domains of cognitive function in elderly living in residential care homes. Study findings need to be interpreted after considering methodological limitations like lack of active comparison group.

Yoga-based intervention for caregivers of outpatients with psychosis: A randomized controlled pilot study

Purpose of the studyThe use of yoga as an intervention for caregivers of patients with psychosis has been poorly studied. The current study aimed to test the efficacy of a brief yoga program as an intervention in caregivers of outpatients with functional psychotic disorders using a randomized controlled research design. Materials and methodsCaregivers who agreed to participate in the study (n=29) were randomized into yoga (n=15) or wait-list group (n=14). They were assessed at baseline and at the end of 3 months. Patients who were randomized into the yoga group were offered supervised yoga training thrice a week for 4 weeks, after which they were instructed to practice at home for the next 2 months. Due to the small sample size and some variables not being normally distributed, non-parametric statistical analysis was used. ResultsResults showed significantly reduced burden scores and improved quality of life scores in the yoga group as compared to the wait-list group at the end of 3 months. There were no significant changes in anxiety and depression scores in caregivers, or psychopathology scores in patients. ConclusionIn caregivers of outpatients with functional psychosis, 4 weeks of training followed by 3 months of home practice of a yoga module offered significant advantage over waitlist. Yoga can be offered as an intervention for caregivers of patients with severe mental disorders. Methods of providing yoga intervention closer to the community or use of flexible modules at hospitals needs further study.

Yoga for reducing perceived stress and back pain at work

Stress and back pain are two key factors leading to sickness absence at work. Recent research indicates that yoga can be effective for reducing perceived stress, alleviating back pain, and improving psychological well-being. To determine the effectiveness of a yoga-based intervention for reducing perceived stress and back pain at work. Participants were recruited from a British local government authority and randomized into a yoga group who received one 50 min Dru Yoga session each week for 8 weeks and a 20 min DVD for home practice and a control group who received no intervention. Baseline and end-programme measurements of self-reported stress, back pain and psychological well-being were assessed with the Perceived Stress Scale, Roland Morris Disability Questionnaire and the Positive and Negative Affect Scale. There were 37 participants in each group. Analysis of variance and multiple linear regression showed that in comparison to the control group, the yoga group reported significant reductions in perceived stress and back pain, and a substantial improvement in psychological well-being. When compared with the control group at the end of the programme, the yoga group scores were significantly lower for perceived stress, back pain, sadness and hostility, and substantially higher for feeling self-assured, attentive and serene. The results indicate that a workplace yoga intervention can reduce perceived stress and back pain and improve psychological well-being. Larger randomized controlled trials are needed to determine the broader efficacy of yoga for improving workplace productivity and reducing sickness absence.

Performance in a Substitution Task and State Anxiety following Yoga in Army Recruits

140 men (M age = 30.3 yr., SD = 5.7) from the Indian army in north India participated in the study. They were naive to yoga and were assigned to yoga and breath awareness groups randomly, with 70 in each group. 20 healthy males of comparable age (M age = 33.7 yr., SD = 7.0) formed a comparison group. Their performance in a digit-letter substitution task and a state anxiety subscale was assessed immediately before and after two 45-min. sessions. The two groups of soldiers practiced either yoga or breath awareness. The comparison group listened to meditation music. Digit-letter substitution scores increased in both groups of army personnel and in the comparison group. State anxiety decreased after yoga and listening to meditation music, but not after breath awareness. This suggests that even in army personnel naive to yoga, a yoga-based intervention or listening to meditation music could reduce anxiety while increasing performance on an attention task.

Effects of a yoga-based intervention for young adults on quality of life and perceived stress: The potential mediating roles of mindfulness and self-compassion

The purpose of this pilot study was to investigate the effects of a yoga-based program on quality of life, perceived stress, mindfulness, and self-compassion in young adults. These variables were measured in 33 self-selected participants of a four-month residential yoga intervention before and after the program. Forty-three demographically matched controls completed the same questionnaires at two time points with a four-month interval inbetween. Participation in the program predicted increases in quality of life and decreases in perceived stress, mediated by mindfulness and self-compassion. Multiple mediator models revealed that the effect of group on quality of life was simultaneously mediated by mindfulness and self-compassion, while the effect of group on perceived stress was only mediated by self-compassion. These positive effects on perceived stress and quality of life suggest that yoga-based interventions may be of value in cultivating subjective well-being in young adults. Furthermore, yoga-based and mindfulness-based interventions may share underlying mechanisms.
