Relationships between physical activity, sleep, and screen time with academic performance and psychological functioning among US children and adolescents with depression.

OBJECTIVE: This cross-sectional study examined the relationships between adherence to 24-HMB guidelines (including physical activity [PA], screen time [ST], and sleep) with academic performance and psychological functioning among children and adolescents with depression. METHODS: This study consists of 2165 participants aged 6-17 years with depression. Independent variables were components of 24-HMB guideline adherence, while outcomes of interest were academic performance (i.e., caring about school performance and completion of required homework) and psychological functioning (i.e., resilience and self-regulation). Logistic regression analysis was conducted while adjusting for confounding variables. RESULTS: Only 1.03 % of the participants adhered to PA + ST + Sleep guidelines. Compared to non-adherence, adherence to PA + ST guidelines was significantly linked to a greater likelihood of caring about school performance (OR = 2.17), while ST + Sleep guidelines adherence was significantly linked to a greater likelihood of caring about school performance (OR = 2.02), completing homework (OR = 2.91), resilience (OR = 2.51), and self-regulation (OR = 2.51). Furthermore, adherence to PA + ST + Sleep guidelines was significantly linked to a higher likelihood of caring about school performance (OR = 5.01), resilience (OR = 2.49), and self-regulation (OR = 2.88) among these participants with depression. CONCLUSION: Adhering to 24-HMB guidelines is positively linked to academic performance and psychological functioning among children and adolescents with depression. Thus, establishing healthy lifestyle behaviors should be promoted in school settings.

A Randomized Controlled Trial of Community-Delivered Heated Hatha Yoga for Moderate-to-Severe Depression.

Objective: To evaluate feasibility, acceptability, and preliminary efficacy of heated yoga to treat moderate-to-severe depression.Design: An 8-week randomized controlled trial (RCT) of heated yoga versus waitlist control was conducted from March 2017 to August 2019.Methods: Participants in the yoga condition were asked to attend heated yoga classes at 2 community heated yoga studios at least twice weekly. We assessed acceptability and feasibility using exit interview and attendance data, respectively. The primary intervention efficacy outcome variable was change in the Inventory of Depressive Symptomatology-Clinician Rated (IDS-CR) score from baseline to post-intervention (week 8).Results: We randomized 80 participants and included 65 (mean [± SD] age 32.7 [± 11.7] years; 81.5% female) in the analyses (yoga n = 33, waitlist n = 32). The mean IDS-CR score at baseline was 35.6 (± 7.9) for the full sample, 36.9 (± 8.8) for yoga participants, and 34.4 (± 6.7) for waitlist participants. Participants attended an average of 10.3 (± 7.1) total classes over the 8-week intervention period. Yoga participants had a significantly greater pre- to post-intervention reduction in IDS-CR scores than waitlist participants (Cohen d = 1.04, P < .001). More yoga participants (59.3%; n = 16) than waitlist participants (6.3%; n = 2) evidenced larger treatment responses (IDS-CR ≥ 50% decrease in symptoms). Participants rated the heated yoga and its aftereffects positively in exit interviews.Conclusions: Approximately 1 heated yoga session per week (mean of 10.3 classes over 8 weeks) was associated with significantly greater reduction in depression symptoms than a waitlist control. Participants rated heated yoga positively. Taken together, results suggest feasibility, acceptability, and preliminary efficacy for patients with depression and warrant further research using active control conditions.Trial Registration: ClinicalTrials.gov identifier: NCT02607514.

What Could Highly Engaged Workers Gain From Mental Health Promotion Programs?: An Exploratory Analysis of Secondary Outcomes of Brief Daily Workplace Well-being Programs.

OBJECTIVE: The current study aims to examine the effects of mental health programs on well-being among highly engaged workers. METHODS: Participants were randomly allocated to body-mind-spiritual or peer support program. Of the whole sample, we examined participants' work engagement and positive affect from the highest quarter and the lowest quarter of work engagement at baseline. Measures were taken at baseline and 1-month intervals during 3-month programs and 3-month follow-up. RESULTS: The programs had decreasing effects on work engagement in the HWE subgroup. There is an increasing trend of positive affect on the HWE group only in the body-mind-spiritual program. The trajectories of work engagement in the HWE group moved toward a moderate level. CONCLUSION: Our results suggest that the work engagement's decrease in the HWE group could be a sign of recovery and relaxation.

Effectiveness of Mindful Self-Compassion Training Supported by Online Peer Groups in China: A Pilot Study.

Context: Self-compassion training involves the cultivation of feelings of warmth and safety, presence, and interconnectedness. Mindful Self-Compassion (MSC) training in a group setting has been found to increase self-compassion, mindfulness, and emotional well-being. Objective: The current study intended to examine the outcomes of live, online, videoconference-based MSC training with online peer-support for nonclinical populations in different cities in China. Design: The research team designed a pre-post pilot study. Setting: The study took place at Renmin University in Beijing, China. Participants: Participants were 253 Chinese individuals who were recruited from different regions in China through online advertisements. Intervention: Participants took part in online MSC training in a two-hour, group class each week for eight weeks and received support from online peer groups and through a half-day in-person retreat. Outcome Measures: Self-report outcomes were obtained at baseline and postintervention, using the Self Compassion Scale (SCS) and the Compassion for Others Scale (CS) for primary outcomes, and the Depression, Anxiety, and Stress Scale (DASS-21), the Fear of Compassion Scale (FOCS), the Satisfaction with Life Scale (SWLS), the Subjective Happiness Scale (SHS), and the Cognitive and Affective Mindfulness Scale (CAMS-R), for secondary outcomes. A fixed effects model was used to test for within-group changes in the scales. Results: The online MSC program yielded a high retention rate. Of the 206 first-time participants, 179 (86.9%) attended six or more of the eight MSC sessions, and 183 (88.8%) completed the assessments at both baseline and postintervention. Of the 183 retained participants, 97.8% were female, with an average age of 37.8 ± 7.9; 94% had college or higher education. For all scales, the within-person changes occurred in the expected direction; positive attributes and experiences increased, while negative attributes and experiences decreased. Conclusions: The study showed that first-time participants in China in an online MSC training that was supported by online peer groups had high attendance rates, high assessment completion, and favorable results. These preliminary outcomes suggest that future studies with more rigorous designs are warranted to further investigate online training with peer support as an effective and efficient approach to disseminate MSC training in China.

How family dementia caregivers perceive benefits of a 4-week Mentalizing Imagery Therapy program: a pilot study.

Background: Family caregivers of dementia patients experience high levels of interpersonal stress that often results in elevated anxiety, and depression, and negative impacts on interpersonal relationships. Changes in behaviors and the structure of relationships with the care recipient (CR) and others in the social milieu challenge the caregivers' ability to mentalize, or understand the links between mental states and behaviors. This study investigates the experiences and perceived benefits of family dementia caregivers who underwent Mentalizing Imagery Therapy (MIT), a treatment aiming to improve balanced self-other mentalizing and reduce psychological symptoms. Methods: Purposeful sampling was used to select 11 family dementia caregivers who underwent a 4-week pilot trial of MIT. Semi-structured interviews were completed post-intervention to identify subjective benefits, putative psychological mediators and perceived active components. Results: Caregivers reported improvements in well-being, mood, anxiety, and sleep, and a majority stated MIT helped with forming and maintaining healthier relationships. Some participants noted benefits extending to how they reacted to their social environment and perceived themselves more objectively from others' perspectives. Specific elements of MIT, including self-compassion, self-care, and the ability to reflect on emotionally arousing challenges, might have mediated these improvements. Conclusion: Family dementia caregivers perceived salutary benefits of MIT on multiple domains of well-being. The self reports suggest MIT holds promise for improving well-being, reducing non-mentalizing patterns of thought, and facilitating improvements in balanced mentalization within the caregivers' relationships.

Study protocol of guided mobile-based perinatal mindfulness intervention (GMBPMI) - a randomized controlled trial.

BACKGROUND: Psychological distress is a common occurrence among women during the perinatal period. Maternal psychological distress (MPS) can also have a negative influence on neonatal outcomes such as infant health, child development or mother-child interaction. Hence, interventions to improve mental wellbeing during this period are vital. Mindfulness based intervention (MBI) has been found to be effective in reducing psychological distress. Delivery of MBI via the internet, making it accessible and inexpensive, is showing a promising positive effect in reducing psychological distress. A randomized control trial with sufficient power is required to confirm its positive effect among pregnant women. The positive effects of MBI have been found to be associated with heart rate variability (HRV) biofeedback; however, the efficacy of MBI on HRV has been rarely studied among pregnant women. Also, the potential association of HRV with MBI and psychological wellbeing needs further examination. This research aims to test the effectiveness of guided mobile-based perinatal mindfulness intervention (GMBPMI) among pregnant women experiencing psychological distress during the pre- and post-natal period, as well as examining the efficacy of GMBPMI on HRV. METHOD: This study is a randomized controlled trial that follows a parallel design. Consenting pregnant women in their second trimester (between 12th and 20th week gestation) will be randomly assigned to an intervention group (GMBPMI) or a control group (psychoeducation). The intended sample size is 198, with 99 participants in each group. Three levels of outcomes will be measured at baseline, post intervention in both the intervention and control groups, and at 36-week gestation and five-week postpartum. The primary outcomes include maternal psychological stress, mindfulness and positive appraisal HRV. Secondary outcomes are psychological and physical wellbeing. Tertiary outcomes include obstetric and neonatal outcomes, and social support. Analyses will follow an intention-to-treat method and repeated measures MANOVA will be conducted to compare changes in primary and secondary outcomes. A series of mixed-effects models will be fitted to assess the mediation effects. DISCUSSION: This trial expects to increase understanding of GMBPMI on HRV and psychological wellbeing for pregnant women, with extended support in both pre-and post-natal periods. The study could also potentially provide evidence for delivery of cost-effective and accessible services to pregnant women. TRIAL REGISTRATION: ClinicalTrials.gov: NCT04876014, registered on 30 March 2021. Protocol Version 1.0., 10 May 2021.

Four-Week Mentalizing Imagery Therapy for Family Dementia Caregivers: A Randomized Controlled Trial with Neural Circuit Changes.

INTRODUCTION: Family caregivers of patients with dementia suffer a high burden of depression and reduced positive emotions. Mentalizing imagery therapy (MIT) provides mindfulness and guided imagery skills training to improve balanced mentalizing and emotion regulation. OBJECTIVE: Our aims were to test the hypotheses that MIT for family caregivers would reduce depression symptoms and improve positive psychological traits more than a support group (SG), and would increase dorsolateral prefrontal cortex (DLPFC) connectivity and reduce subgenual anterior cingulate cortex (sgACC) connectivity. METHODS: Forty-six caregivers participated in a randomized controlled trial comparing a 4-week MIT group (n = 24) versus an SG (n = 22). Resting state neuroimaging was obtained at baseline and post-group in 28 caregivers, and questionnaires completed by all participants. The primary outcome was change in depression; secondary measures included anxiety, mindfulness, self-compassion, and well-being. Brain networks with participation of DLPFC and sgACC were identified. Connectivity strengths of DLPFC and sgACC with respective networks were determined with dual regression. DLPFC connectivity was correlated with mindfulness and depression outcomes. RESULTS: MIT significantly outperformed SG in improving depression, anxiety, mindfulness, self-compassion, and well-being, with moderate to large effect sizes. Relative to SG, participants in MIT showed significant increases in DLPFC connectivity - exactly replicating pilot study results - but no change in sgACC. DLPFC connectivity change correlated positively with mindfulness and negatively with depression change. CONCLUSIONS: In this trial, MIT was superior to SG for reducing depression and anxiety symptoms and improving positive psychological traits. Neuroimaging results suggested that strengthening DLPFC connectivity with an emotion regulation network might be mechanistically related to MIT effects.

Barriers and Facilitators to Advance Care Planning among Chinese Patients with Advanced Cancer and Their Caregivers.

Background: Chinese American adults experience health disparities at the end of life. Culturally tailored advance care planning (ACP) may promote goal-concordant care across the continuum of serious illness. However, seriously ill Chinese Americans' preferences for ACP remain unknown. Objective: To explore barriers and facilitators to ACP among Chinese patients with advanced cancer and their caregivers. Design: Informed by socioecological theory, we conducted an exploratory qualitative study using semistructured interviews that were thematically analyzed. Setting/Participants: We recruited participants at one U.S. comprehensive cancer center. Of 27 eligible patients approached, we recruited 20 patients (74.1%) and 8 accompanying caregivers. Overall, participants were middle aged (55.6 ± 13.5 years), 60.7% female, 85.7% partnered/married, 89.3% college educated, and had low acculturation (mean Suinn-Lew Asian Self-Identify Acculturation = 2.0 ± 1.6/5.0). More patients were privately insured (35%) than self-pay (30%), Medicare (25%), and Medicaid (10%). Caregivers were split between "spouse" and "child." Results: Findings highlight participants' trust in their clinicians and the study institution as primary supports for clinicians to lead ACP. However, participants' preconceptions of clinicians' professional responsibilities and participants' belief in an uncertain future may hinder an open discussion of goals and values for future medical care. A key moderating factor in how participants view ACP may be their level of acculturation to local care, behavioral, and communication norms. Conclusions: Chinese patients may prefer a routinized clinician-led ACP approach that supports their actionable priorities in the present by leveraging patient-clinician trust, gauging acculturation level, and using indirect communication strategies. Future studies should investigate preferred communication strategies to support in-the-moment care planning.

Use of the Move to Emptiness Technique, A Mind-Body Exercise for Treating Trauma and Post-Traumatic Stress Disorder: A Case Report.

CONTEXT: The paper reports a case of trauma treated by the Move to Emptiness Technique (MET), which is a therapy to alleviate patient's physical or psychological symptom related to trauma by combining Qigong with imagery, metaphor and suggestions. OBJECTIVE: To introduce MET and report treating a patient with trauma using MET. INTERVENTION: The patient was guided to visualize a symbolic object that represented the physical or psychological symptom of the traumatic experience, and visualize moving the symbolic object to the farthest possible space of "emptiness", where the object became imperceptible. At the same time, the patient embodied the physical and emotional sensations of the symbolic object and its container, and focused on the changes in his sensations when moving them. OUTCOME MEASURES: A self-assessment was used to score the patient's distress form 0 to 10, 10 being the worst before and after intervention. RESULTS: The score of distress dropped form 8/10 to 2/10. The patient improved a lot and was better able to manage his emotions and communicate with his parents after resolving his conflict. CONCLUSIONS: MET may be an alternative to commonly used trauma-focused treatments. It is safe and easy to learn for therapists and patients.

Validation of the Chinese Version of Relaxation Sensitivity Index: A Tool for Predicting Treatment Effect in Mindfulness Interventions.

Background: The Relaxation Sensitivity Index (RSI) measures relaxation-related fears developed and validated in western samples. The RSI captures three facets of fear regarding relaxation: physical, cognitive, and social concerns. This study aimed to translate and identify the factor structure of the Chinese version of the RSI. Methods: In a preliminary study, 26 items were generated mainly by translation and modified from the original RSI. In Study 1, factor analysis and internal consistency reliability analysis were conducted on separated half samples of 597 Chinese college students. In Study 2, test-retest reliability, convergent, and predictive criterion validity were examined based on 465 Chinese college students. Results: Fourteen items were selected based on the factor loading and item prevalence in the preliminary study. Factor analysis based on Study 1 identified three factors: Social appealing, Social performance, and Physical concerns. In general, the RSI demonstrated good internal consistency (αs = 0.750-0.860), convergent validity and predictive criterion validity, while the test-retest reliability is relatively low (rs = 0.525-0.685). Notably, less related to the other two factors, Social performance concerns may be a unique factor solely predicting social anxiety (p <0.001), but not relaxation-induced anxiety (p = 0.442). Conclusion: The Chinese version of the RSI possesses a factor structure different from the western population. The robustness of factor structure and test-retest reliability was not as good as expected. Further research is warranted to explore the validity of the RSI in Chinese samples.

Tai Chi for Chronic Illness Management: Synthesizing Current Evidence from Meta-Analyses of Randomized Controlled Trials.

An umbrella review of systematic reviews and meta-analyses of randomized controlled trials (RCTs) was conducted to evaluate the existing evidence of Tai Chi as a mind-body exercise for chronic illness management. MEDLINE/PubMed and Embase databases were searched from inception until March 31, 2019, for meta-analyses of at least two RCTs that investigated health outcomes associated with Tai Chi intervention. Evidence of significant outcomes (P value < 0.05) was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. This review identified 45 meta-analyses of RCTs and calculated 142 summary estimates among adults living with 16 types of chronic illnesses. Statistically significant results (P value < 0.05) were identified for 81 of the 142 outcomes (57.0%), of which 45 estimates presenting 30 unique outcomes across 14 chronic illnesses were supported by high (n = 1) or moderate (n = 44) evidence. Moderate evidence suggests that Tai Chi intervention improved physical functions and disease-specific outcomes compared with nonactive controls and improved cardiorespiratory fitness compared with active controls among adults with diverse chronic illnesses. Between-study heterogeneity and publication bias were observed in some meta-analyses.

The Effects of Tai Chi and Qigong on Immune Responses: A Systematic Review and Meta-Analysis.

Background: Effective preventative health interventions are essential to maintain well-being among healthcare professionals and the public, especially during times of health crises. Several studies have suggested that Tai Chi and Qigong (TQ) have positive impacts on the immune system and its response to inflammation. The aim of this review is to evaluate the current evidence of the effects of TQ on these parameters. Methods: Electronic searches were conducted on databases (Medline, PubMed, Embase and ScienceDirect). Searches were performed using the following keywords: "Tai Chi or Qigong" and "immune system, immune function, immunity, Immun*, inflammation and cytokines". Studies published as full-text randomized controlled trials (RCTs) in English were included. Estimates of change in the levels of immune cells and inflammatory biomarkers were pooled using a random-effects meta-analysis where randomised comparisons were available for TQ versus active controls and TQ versus non-active controls. Results: Nineteen RCTs were selected for review with a total of 1686 participants and a range of 32 to 252 participants within the studies. Overall, a random-effects meta-analysis found that, compared with control conditions, TQ has a significant small effect of increasing the levels of immune cells (SMD, 0.28; 95% CI, 0.13 to 0.43, p = 0.00), I2 = 45%, but not a significant effect on reducing the levels of inflammation (SMD, -0.15; 95% CI, -0.39 to 0.09, p = 0.21), I2 = 85%, as measured by the systemic inflammation biomarker C-reactive protein (CRP) and cell mediated biomarker cytokines. This difference in results is due to the bidirectional regulation of cytokines. An overall risk of bias assessment found three RCTs with a low risk of bias, six RCTs with some concerns of bias, and ten RCTs with a high risk of bias. Conclusions: Current evidence indicates that practising TQ has a physiologic impact on immune system functioning and inflammatory responses. Rigorous studies are needed to guide clinical guidelines and harness the power of TQ to promote health and wellbeing.

Distinct Insular Functional Connectivity Changes Related to Mood and Fatigue Improvements in Major Depressive Disorder Following Tai Chi Training: A Pilot Study.

Objective: Tai chi (TC), a contemplative practice combining slow movements and deep breathing, has been shown to be clinically effective in alleviating depressive symptoms. Feelings of fatigue or low vitality often accompany major depressive disorder (MDD) though they are commonly overlooked and not well understood neurologically. By using resting state functional connectivity (rs-FC) using the insula as the seed, this study examines the relationship between mood and vitality symptoms in MDD and how they are impacted by TC training. Methods: Patients (N = 16) with MDD participated in a 10-week TC intervention. Self-report scores of vitality (using the SF-36 scale) and depressed mood (using the Beck Depression Inventory) as well as rs-fMRI were collected pre- and post-intervention. A seed-to-voxel approach was used to test whether changes in insular rs-FC were related to therapeutic improvement in MDD-related symptoms resulting from TC practice. Results: We found decreased self-reported depressed mood and increased vitality following the TC intervention. Furthermore, decreases in depressed mood were associated with increased rs-FC between the right anterior insula (AIC) and superior temporal gyrus and caudate (cluster-corrected p < 0.05). Increased vitality was associated with increased rs-FC between the right posterior insula (PIC) and regions associated with sensorimotor processes (cluster-corrected p < 0.05). Conclusion: These results provide support for differential changes in insula connectivity as neural correlates of symptom improvement in MDD.

Qigong for the Prevention, Treatment, and Rehabilitation of COVID-19 Infection in Older Adults.

The elderly are at high risk of contracting respiratory infectious diseases, including COVID-19 infection. The recent pandemic has the potential to cause significant physical and mental damage in older adults. Similarly to other mind-body exercises in Traditional Chinese medicine, Qigong features regulation of breath rhythm and pattern, body movement and posture, and meditation. Given these traits, Qigong has the potential to play a role in the prevention, treatment, and rehabilitation of respiratory infections, such as COVID-19. Potential mechanisms of action include stress reduction, emotion regulation, strengthening of respiratory muscles, reduction of inflammation, and enhanced immune function. Three forms of Qigong; abdominal breathing, Ba Duan Jin and Liu Zi Jue, all of which are gentle, smooth, and simple for the elderly to practice, are recommended in this context.

Dao Yin (a.k.a. Qigong): Origin, Development, Potential Mechanisms, and Clinical Applications.

Dao Yin is a form of exercise combining physical movements, mental focus, and breathing originated in ancient China. In this review, we introduce the history in the development and the scope of Dao Yin, the relationship between Dao Yin with Taoist culture and Qigong, and the potential mechanisms of how Dao Yin promotes health and alleviate illnesses. Empirical research studies using Dao Yin for treatment of lumbar spondylosis, peripheral musculoskeletal diseases, cervical spondylosis, heart diseases, central nervous system disorders, immunological dysfunction, and psychological disorders are detailed.

Superior Effects of Modified Chen-Style Tai Chi versus 24-Style Tai Chi on Cognitive Function, Fitness, and Balance Performance in Adults over 55.

BACKGROUND: Cognitive decline and balance impairment are prevalent in the aging population. Previous studies investigated the beneficial effects of 24-style Tai Chi (TC-24) on either cognitive function or balance performance of older adults. It still remains largely unknown whether modified Chen-style TC (MTC) that includes 18 complex movements is more beneficial for these age-related health outcomes, as compared to TC-24. OBJECTIVE: We investigated if MTC would show greater effects than TC-24 on global cognitive function and balance-related outcomes among older adults. METHODS: We conducted a randomized trial where 80 eligible adults aged over 55 were allocated into two different styles of Tai Chi (TC) arms (sixty-minute session × three times per week, 12 weeks). Outcome assessments were performed at three time periods (baseline, Week 6, and Week 12) and included the Chinese Version of the Montreal Cognitive Assessment (MoCA) for overall cognitive function, One-leg Standing Test (LST) for static balance, Timed Up and Go Test (TUGT) for dynamic balance, chair Stand Test (CST) for leg power, and the six-meter Walk Test (6MWT) for aerobic exercise capacity. RESULTS: Compared to TC-24 arm, MTC arm demonstrated significantly greater improvements in MoCA, LST, TUGT, CST, and 6MWT (all p < 0.05). CONCLUSIONS: Both forms of TC were effective in enhancing global cognitive function, balance, and fitness. Furthermore, MTC was more effective than TC-24 in enhancing these health-related parameters in an aging population.

Are Mindful Exercises Safe and Beneficial for Treating Chronic Lower Back Pain? A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Chronic low back pain (CLBP) is a common health issue worldwide. Tai Chi, Qigong, and Yoga, as the most widely practiced mindful exercises, have promising effects for CLBP-specific symptoms. OBJECTIVE: We therefore conducted a comprehensive review investigating the effects of mindful exercises versus active and/or non-active controls while evaluating the safety and pain-related effects of mindful exercises in adults with CLBP. METHODS: We searched five databases (MEDLINE, EMBASE, SCOPUS, Web of Science, and Cochrane Library) from inception to February 2019. Two investigators independently selected 17 eligible randomized controlled trials (RCT) against inclusion and exclusion criteria, followed by data extraction and study quality assessment. Standardized mean difference (SMD) was used to determine the magnitude of mindful exercises versus controls on pain- and disease-specific outcome measures. RESULTS: As compared to control groups, we observed significantly favorable effects of mindful exercises on reducing pain intensity (SMD = -0.37, 95% CI -0.5 to -0.23, p < 0.001, I2 = 45.9 %) and disability (SMD = -0.39, 95% CI -0.49 to -0.28, p < 0.001, I2 = 0 %). When compared with active control alone, mindful exercises showed significantly reduced pain intensity (SMD = -0.40, p < 0.001). Furthermore, of the three mindful exercises, Tai Chi has a significantly superior effect on pain management (SMD= -0.75, 95% CI -1.05 to -0.46, p < 0.001), whereas Yoga-related adverse events were reported in five studies. CONCLUSION: Findings of our systematic review suggest that mindful exercises (Tai Chi and Qigong) may be beneficial for CLBP symptomatic management. In particular, Tai Chi appears to have a superior effect in reducing pain intensity irrespective of non-control comparison or active control comparison (conventional exercises, core training, and physical therapy programs). Importantly, training in these mindful exercises should be implemented with certified instructors to ensure quality of movement and injury prevention.

The Beneficial Effects of Mind-Body Exercises for People With Mild Cognitive Impairment: a Systematic Review With Meta-analysis.

OBJECTIVE: To objectively evaluate the most common forms of mind-body exercise (MBE) (tai chi, yoga, qigong) on cognitive function among people with mild cognitive impairment (MCI). DATA SOURCES: We searched 6 electronic databases (Scopus, PubMed, PsycINFO, WanFang, Web of Science, CNKI) from inception until September 2018. STUDY SELECTION: Nine randomized controlled trials and 3 nonrandomized controlled trials were included for meta-analysis. DATA EXTRACTION: Two researchers independently performed the literature searches, study selection, data extraction, and methodological quality assessment using the revised Physiotherapy Evidence Database (PEDro) scale. DATA SYNTHESIS: The pooled effect size (standardized mean difference [SMD]) was calculated while random-effect model was selected. Overall results of the meta-analysis (N=1298 people with MCI) indicated that MBE significantly improved attention (SMD=0.39, 95% confidence interval [CI] 0.07-0.71, P=.02, I2=31.6%, n=245), short-term memory (SMD=0.74, 95% CI 0.57-0.90, P<.001, I2=0%, n=861), executive function (SMD=-0.42, 95% CI -0.63 to -0.21, P<.001, I2=38.54%, n=701), visual-spatial/executive function (SMD=0.35, 95% CI 0.07-0.64, P<.05, I2=0%, n=285), and global cognitive function (SMD=0.36, 95% CI 0.2-0.52, P<.001, I2=15.12%, n=902). However, the significant positive effect on cognitive processing speed was not observed following MBE interventions (SMD=0.31, 95% CI -0.01 to 0.63, P=.054, I2=28.66%, n=233). CONCLUSIONS: Study findings of this meta-analysis suggest that MBE have the potential to improve various cognitive functions in people with MCI.

Wuqinxi Qigong as an Alternative Exercise for Improving Risk Factors Associated with Metabolic Syndrome: A Meta-Analysis of Randomized Controlled Trials.

Background: The improvement of living standards has led to increases in the prevalence of hypokinetic diseases. In particular, multifactorial complex diseases, such as metabolic syndrome, are becoming more prevalent. Currently, developing effective methods to combat or prevent metabolic syndrome is of critical public health importance. Thus, we conducted a systematic review to evaluate the existing literature regarding the effects of Wuqinxi exercise on reducing risk factors related to metabolic syndrome. Methods: Both English- and Chinese-language databases were searched for randomized controlled trials investigating the effects of Wuqinxi on these outcomes. Meanwhile, we extracted usable data for computing pooled effect size estimates, along with the random-effects model. Results: The synthesized results showed positive effects of Wuqinxi exercise on systolic blood pressure (SBP, SMD = 0.62, 95% CI 0.38 to 0.85, p < 0.001, I2 = 24.06%), diastolic blood pressure (DBP, SMD = 0.62, 95% CI 0.22 to 1.00, p < 0.001, I2 = 61.28%), total plasma cholesterol (TC, SMD = 0.88, 95% CI 0.41 to 1.36, p < 0.001, I2 = 78.71%), triglyceride (TG, SMD = 0.87, 95% CI 0.49 to 1.24, p < 0.001, I2 = 67.22%), low-density lipoprotein cholesterol (LDL-C, SMD = 1.24, 95% CI 0.76 to 1.72, p < 0.001, I2 = 78.27%), and high-density lipoprotein cholesterol (HDL, SMD = 0.95, 95% CI 0.43 to 1.46, p < 0.001, I2 = 82.27%). In addition, regression results showed that longer-duration Wuqinxi intervention significantly improved DBP (ß = 0.00016, Q = 5.72, df = 1, p = 0.02), TC (ß = -0.00010, Q = 9.03, df = 1, p = 0.01), TG (ß = 0.00012, Q = 6.23, df = 1, p = 0.01), and LDL (ß = 0.00011, Q = 5.52, df = 1, p = 0.02). Conclusions: Wuqinxi may be an effective intervention to alleviate the cardiovascular disease risk factors of metabolic syndrome.
