Effects of Ving Tsun sticking-hand training on lower limb sensorimotor performance among community-dwelling middle-aged and older adults: a randomized controlled trial.

BACKGROUND: To explore the effects of Ving Tsun (VT) sticking-hand training on knee joint proprioception and leg muscular performance among community-dwelling middle-aged and older adults. METHODS: Thirty-three middle-aged and older adults were randomly assigned to either the VT or control group. The VT group received sticking-hand training twice/week for 3 months. Data were collected before and after the intervention period. The primary outcome was knee joint repositioning error, which was measured using knee joint active repositioning tests. The secondary outcomes included the maximum muscle strength and time to maximum muscle strength of the major leg muscles. RESULTS: No significant group, time, or group-by-time interaction effects were found for the knee joint repositioning error (p > 0.05). The maximum muscle strength of the knee flexors increased over time in the VT group only (p = 0.038). In addition, the time to maximum muscle strength in the hip extensors and flexors increased over time in both groups (p < 0.05). For the knee extensors and flexors, the time to maximum muscle strength increased in the control (p = 0.027) and VT (p = 0.019) groups, respectively, over time. CONCLUSIONS: VT sticking-hand training could improve the maximum muscle strength of the knee flexors but could not attenuate the age-related deterioration in leg muscle contraction speed nor improve knee joint proprioception among community-dwelling middle-aged and older adults.

A self-administered moxibustion-cum-massage intervention for older adults with chronic pain in the community: A randomized controlled trial.

OBJECTIVES: To determine the effectiveness of a simple, self-administrable moxibustion-cum-massage intervention for relieving chronic pain and improving psychological well-being for older adults in the community. DESIGN: A randomized controlled trial. SETTING: Seventy-eight participants with chronic pain were randomly assigned to the intervention and waitlist control groups. INTERVENTIONS: Participants received two moxa sticks a day to use the moxibustion-cum-massage procedure with the help of trained volunteers or caregivers for five consecutive days. MAIN OUTCOME MEASURES: Participates' pain level, sleep quality, depression and subjective well-being were measured before the intervention (T0), immediately after the intervention (T1), and one week after the intervention (T2). RESULTS: Repeated measures ANOVA revealed a significant group × time interaction effect in subjective well-being with a medium effect size. Regarding within-group effects in the intervention group at post-intervention (T1), the subjective pain level was significantly reduced with a small effect size, while sleep quality and depression significantly improved with large effect sizes. The control group showed no significant within-group effects in these variables. Maintenance effects at follow-up (T2) were not significant. CONCLUSION: Despite the short intervention timeframe of five days, the study revealed preliminary evidence that the moxibustion-cum-massage intervention can be an effective, self-administrable pain relief regime for older adults. A longer period of intervention time is suggested for future studies.

Impact of mind-body intervention on proinflammatory cytokines interleukin 6 and 1ß: A three-arm randomized controlled trial for persons with sleep disturbance and depression.

Depressed people are prone to sleep disturbance, which may in return perpetuate the depression. Both depression and sleep disturbance influence proinflammatory cytokines interleukin (IL) 6 and 1ß. Thus interventions for depression should consider the effect on sleep disturbance, and vice versa. Integrative Body-Mind-Spirit (IBMS) and Qigong interventions have been applied in a wide range of health and mental health conditions, including depression and sleep disturbance. This study aimed to evaluate the effect of these two mind-body therapies for persons with both depressive symptoms and sleep disturbance. A three-arm randomized controlled trial was conducted among 281 participants, who were randomly assigned to either IBMS, Qigong or wait list control group. Participants in IBMS and Qigong groups received eight weekly sessions of intervention. Outcome measures were plasma concentrations of IL-6 and IL-1ß, and a questionnaire containing Pittsburgh Sleep Quality Index, Center for Epidemiologic Studies Depression Scale, Somatic Symptom Inventory, Perceived Stress Scale and Body-Mind-Spirit Holistic Well-being Scale. Outcomes were assessed at baseline (T0), immediate post-intervention (T1) and at three-months post-intervention (T2). Besides intervention efficacy analysis, path analysis was performed to explore the relations among perceived stress, depression, sleep disturbance, and IL-6 and IL-1ß values. The study found both IBMS and Qigong reduced depression, sleep disturbance, painful and painless somatic symptoms, IL-6 and IL-1ß levels, and increased holistic well-being. The effect sizes of IBMS and Qigong, mostly in the medium magnitude range, were approximatively equivalent. Path analysis models revealed a predictive role of perceived stress in depression and sleep disturbance, a bidirectional relationship between depression and sleep disturbance, and significant influence of depression and sleep disturbance on IL-6 and IL-1ß. Compared with control, the findings support the efficacy of IBMS and Qigong interventions in relieving depression and sleep disturbance, and in reducing IL-6 and IL-1ß levels.

Physical activity, confidence and quality of life among cancer patient-carer dyads.

BACKGROUND: Physical activity (PA) has been positively associated with health-related quality of life (HRQoL) among cancer patients and family caregivers. However, there has been no relevant research for patient-caregiver dyads. METHODS: Path analysis, based on the actor-partner interdependence model (APIM), was used to examine the relationship between physical activity and health-related quality of life and explore the mediating role of emotional distress in 233 dyads. RESULTS: In both patients and caregivers, physical activity had a direct positive effect on physical quality of life (QoL) but not on mental. There was a significant indirect effect of physical activity on health-related quality of life via emotional distress for both dyad members. Patients' and caregivers' confidence in fighting cancer was negatively associated with their own emotional distress. Caregivers' confidence in fighting cancer was positively associated with their physical activity and also negatively associated with patients' emotional distress. CONCLUSIONS: Physical activity may be considered as a possible behavioral and rehabilitation strategy for improving health-related quality of life in patient-caregiver dyads and reducing negative symptoms. Future research and intervention may consider cancer patient-family caregiver dyad as a unit of care.

The Counterintuitive Relationship between Telomerase Activity and Childhood Emotional Abuse: Culture and Complexity.

BACKGROUND: A burgeoning literature has found relationships between telomere length, telomerase activity, and human health and longevity. Although some research links a history of childhood adversity with shortened telomere length, our review found no prior research on the relationship between child maltreatment history and telomerase activity in adulthood. We hypothesized a negative relationship between child maltreatment and telomerase activity and hypothesized that the association would be moderated by sex. METHODS: These relationships were tested on a sample of 262 Hong Kong Chinese adults (200 females versus 62 males) with mild to moderate depression. RESULTS: Counterintuitively, emotional abuse was positively associated with telomerase activity, while other maltreatment types were non-significant. The positive relationship between emotional abuse and telomerase activity was significantly moderated by the sex of the participant. CONCLUSIONS: We advance two possible explanations for this finding (1) a culturally informed resilience explanation and (2) a homeostatic complexity explanation. The two explanations are not mutually exclusive. This trial is registered under Hong Kong Clinical Trial Register number HKCTR-1929. SIGNIFICANCE STATEMENT: Emotional abuse was significantly positively associated with telomerase activity. There are at least two non-mutually exclusive explanations for the findings. Simply put, either (1) in the cultural context of Hong Kong emotional abuse was not a risk factor, and/or (2) the conceptualization of telomerase activity as a straightforward indicator of longevity is overly simplistic. The first story we might term a "resilience explanation" while the second we might call a "homeostatic complexity" story.

Trust as a mediator in the relationship between childhood sexual abuse and IL-6 level in adulthood.

Childhood sexual abuse (CSA) has been shown to predict the coupling of depression and inflammation in adulthood. Trust within intimate relationships, a core element in marital relations, has been shown to predict positive physical and mental health outcomes, but the mediating role of trust in partners in the association between CSA and inflammation in adulthood requires further study. The present study aimed to examine the impact of CSA on inflammatory biomarkers (IL-6 and IL-1ß) in adults with depression and the mediating role of trust. A cross-sectional survey data set of adults presenting with mood and sleep disturbance was used in the analysis. CSA demonstrated a significant negative correlation with IL-6 level (r = -0.28, p<0. 01) in adults with clinically significant depression, while trust showed a significant positive correlation with IL-6 level (r = 0.36, p < .01). Sobel test and bootstrapping revealed a significant mediating role for trust between CSA and IL-6 level. CSA and trust in partners were revealed to have significant associations with IL-6 level in adulthood. Counterintuitively, the directions of association were not those expected. Trust played a mediating role between CSA and adulthood levels of IL-6. Plausible explanations for these counterintuitive findings are discussed.

Comparing the efficacy of integrative body-mind-spirit intervention with cognitive behavioral therapy in patient-caregiver parallel groups for lung cancer patients using a randomized controlled trial.

Purposes/objectives: This paper reports the comparative efficacies of integrative body-mind-spirit intervention (I-BMS) and cognitive behavioral therapy (CBT) in patient-caregiver parallel groups for Chinese patients with lung cancer.Design: Randomized controlled trial (RCT).Methods: One hundred and fifty-seven patient-caregiver dyads with no marked functional impairment were randomized into one of the two interventions with eight weekly patient-caregiver parallel groups. Assessments were conducted at baseline, within one, eight- and sixteen-weeks post-intervention. Effects of treatment group across time were analyzed by multilevel modeling.Findings: CBT led to greater reduction in emotional vulnerability than I-BMS. I-BMS resulted in greater increase in overall QoL and spiritual self-care, and more reduction in depression than CBT. Patients in both interventions experienced improvement in physical, emotional and spiritual, except social, domains of QoL.Conclusion: I-BMS was more efficacious for diverse domains of QoL, and CBT was more effective for emotional well-being, despite the relatively small between-group effect sizes.Implications for psychosocial providers/policy: (1) With the expanding repertoire of psychosocial interventions for families facing lung cancer, it has become imperative to investigate the comparative efficacies of empirically supported and culturally adapted interventions. (2) Our findings show that I-BMS was more effective for diverse domains of QoL, while CBT was more efficacious with emotional well-being, although both interventions led to significant improvements in physical, emotional and spiritual domains of patient QoL. (3) Patient-caregiver parallel groups have been shown to be effective for enhancing QoL of Chinese lung cancer patients. (4) Care professionals are encouraged to dispense interventions based on the idiosyncratic needs and preferences of the patients to maximize the treatment effects.

Qigong exercise for chronic fatigue syndrome.

Chronic fatigue syndrome (CFS) is often overlooked, has unclear etiology and no effective cure except some symptomatic treatments. Additionally, most people with CFS do not seek medical attention. Qigong exercise, an ancient Eastern body-mind-spirit practice, has been long practiced in Chinese communities and may powerfully trigger the self-healing process. Using full baseline data (n=1409), the average Hong Kong CFS respondent was found to be female, married, 42.5yo, highly educated and employed full-time, experiencing sleep disturbance (~95%), anxiety (>80%), and depressive symptoms (68%). Here, we summarized our previous studies to evaluate the potential of Qigong as a complementary and alternative therapy for CFS. Two randomized controlled trials were conducted (RCT1 n1=137, RCT2 n2=150). In both trials, extensive online questionnaires allowed individuals with CFS-like illness (i.e., symptoms match CFS, yet without clinical confirmation) to be identified. RCT1 included a 5-week intervention. The intervention in RCT2 was 8weeks. In RCT1 Qigong group had reduced fatigue (P<0.001) and depressive symptoms (P=0.002), and improved telomerase activity (P=0.029). An effective practice regimen was identified (≥3 days/week, at ≥30min/session). Methods were slightly adjusted for RCT2, which replicated RCT1 findings, and further documented improved subjective sleep quality (P=0.008) and adiponectin levels (P<0.05). A significant dose-response relationship was founded. Thus, Qigong exercise should be recognized as a possible standalone therapy and self-management skill in CFS. Strategies are needed to increase motivation for regular practice and to explore its possibility of self-management skill in brain health. Further clarity would come from studies comparing Qigong with other physical exercises.

Stress and psychosomatic symptoms in Chinese adults with sleep complaints: mediation effect of self-compassion.

Although stress has been widely acknowledged to link to psychosomatic dysfunctioning, the underlying mechanism that transmits the impact is not adequately investigated. This study examined self-compassion as a potential mediator that may explain the pathway from stress to depressive and somatic symptoms. Data in the present study were drawn from a baseline survey of 998 Chinese participants who enrolled in an intervention study on sleep disturbance in Hong Kong. Participants completed measures of perceived stress, self-compassion, depressive symptoms, and somatic symptoms. The results showed that stress was associated with depressive symptoms (r = .79, p < .01) and somatic symptoms (r = .47, p < .01). The path analyses showed that low levels of self-compassion mediated the association between stress and psychosomatic symptoms. Our findings provide insight into the pathway how stress affects psychosomatic symptoms. The intervention programs for stress management to improve psychological and physical functioning are recommended to consider self-compassion as a promising component in practice.

Effects of Meditative Movements on Major Depressive Disorder: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Tai Chi, Qigong, and Yoga are recognized as the most popular complementary approaches for alleviating musculoskeletal pain, improving sleep quality, and reducing blood pressure. The therapeutic effects of these meditative movements for treating major depressive disorder (MDD) is yet to be determined. Therefore, we examined whether meditative movements (Tai Chi, Qigong, and Yoga) are effective for treating MDD. Seven electronic databases (SPORTDiscus, PubMed, PsycINFO, Cochrane Library, Web of Science, CNKI, and Wanfang) were used to search relevant articles. Randomized controlled trials (RCT) using Tai Chi, Qigong or Yoga as intervention for MDD were considered for the meta-analysis (standardized mean difference: SMD). RESULTS: Meta-analysis on 15 fair-to-high quality RCTs showed a significant benefit in favor of meditative movement on depression severity (SMD = -0.56, 95% CI -0.76 to -0.37, p < 0.001, I² = 35.76%) and on anxiety severity (SMD = -0.46, 95% CI -0.71 to -0.21, p < 0.001, I² = 1.17%). Meditative movement interventions showed significantly improved treatment remission rate (OR = 6.7, 95% CI 2.38 to 18.86, p < 0.001) and response rate (OR = 5.2, 95% CI 1.73 to 15.59, p < 0.001) over passive controls. CONCLUSIONS: Emphasizing the therapeutic effects of meditative movements for treating MDD is critical because it may provide a useful alternative to existing mainstream treatments (drug therapy and psychotherapy) for MDD. Given the fact that meditative movements are safe and easily accessible, clinicians may consider recommending meditative movements for symptomatic management in this population.

Mindfulness-Based Baduanjin Exercise for Depression and Anxiety in People with Physical or Mental Illnesses: A Systematic Review and Meta-Analysis.

OBJECTIVES: we used a quantitative method to systematically synthesize the emerging literature and critically evaluate the effects of Baduanjin on depression and anxiety in people with physical or mental illnesses. Additionally, we determined if the number of total Baduanjin training sessions is associated with decreased anxiety and depression levels. METHODS: both English and Chinese databases were searched for potential studies published between January 1982 and October 2017. The eligible randomized controlled trials were considered for meta-analysis. Effect size (Hedge's g) was computed for the pooled effects while the random-effect model was set. For moderator analysis; Subgroup meta-analysis for categorical variables and meta-regression for continuous variables were performed. RESULTS: the aggregated result has shown a significant benefit in favour of Baduanjin on anxiety (Hedge's g = -0.99; CI -1.63 to -0.74) and depression (Hedge's g = -1.07; CI -1.3 to -0.83). For continuous potential moderators; meta-regression indicated a significant effect for total hours in Baduanjin practice (ß = -0.0053; 95% CI -0.009 to -0.0014; p = 0.008). With regard to depression; meta-regression indicated a significant effect for total sessions of Baduanjin practice (ß = -0.0023; 95% CI -0.006 to -0.0004; p = 0.028). CONCLUSIONS: the encouraging findings indicate the efficacy of Baduanjin exercise in reducing depression and anxiety symptoms in people with physical or mental illnesses. However; the results should be interpreted with caution because of existing methodological limitations (e.g., high risk of bias; Baduanjin combined with other behavioral interventions; and heterogeneity of control groups).

Study protocol of a randomized controlled trial comparing integrative body-mind-spirit intervention and cognitive behavioral therapy in fostering quality of life of patients with lung cancer and their family caregivers.

Compared to cancers at other sites, lung cancer often results in greater psychosocial distress to both the patients and their caregivers, due to the poor prognosis and survival rate, as well as the heavy symptom burden. In recent years, making protocols of proposed or on-going studies publicly available via clinical trial registries and/or peer-reviewed journals has benefited health sciences with timely communication of the latest research trends and improved transparency in reporting. However, such practice is yet to be a common sight in evidence-informed social work. Hence, this paper discusses the value of publishing protocols in social work research and presents the protocol of a randomized controlled trial that compares the effectiveness of integrative body-mind-spirit intervention with cognitive behavioral therapy for enhancing quality of life of patients with lung cancer and their family caregivers. The data collection process was still on-going at the time of manuscript submission.

Qigong and Tai-Chi for Mood Regulation.

Qigong and Tai-Chi are traditional self-healing, self-cultivation exercises originating in ancient China. These exercises are characterized by coordinated body posture and movements, deep rhythmic breathing, meditation, and mental focus based on traditional Chinese medicine theories. Although the exact mechanisms of Qigong's and Tai-Chi's effects on physical and mental well-being are unknown, these practices may be viewed as meditative movements and share many of the healing elements observed in mindfulness meditation. Clinical studies including randomized controlled trials and meta-analyses have shown that both Qigong and Tai-Chi have beneficial effects on psychological well-being and reduce symptoms of anxiety and depression. Qigong and Tai-Chi frequently involve anchoring attention to interoceptive sensations related to breath or other parts of the body, which has been shown to enhance nonreactivity to aversive thoughts and impulses. Preliminary studies suggest that the slow movements in Qigong and Tai-Chi with slowing of breath frequency could alter the autonomic system and restore homeostasis, attenuating stress related to hypothalamus-pituitary-adrenal axis reactivity and modulating the balance of the autonomic nervous system toward parasympathetic dominance. Qigong's and Tai-Chi's effects on emotion regulation could occur through changes in multiple prefrontal regions, the limbic system, and the striatum or in the expression of genes linked to inflammatory responses and stress-related pathways.

Integrative body-mind-spirit intervention for concurrent sleep and mood disturbances: sleep-specific daytime functioning mediates sleep and mood improvements.

Sleep disturbances and depressive symptoms are associated closely with daytime dysfunctions, yet few studies have investigated their temporal relationship in a randomized controlled trial. We investigated the inter-relationships among sleep, depressive symptoms and daytime functioning following an integrative body-mind-spirit (I-BMS) intervention. One hundred and eighty-five participants (mean age 55.28 years, 75.1% female) with co-existing sleep and depressive symptoms were randomized to I-BMS or waiting-list. Daytime functioning variables included the daytime dysfunction items of the Pittsburg Sleep Quality Index (PSQI-day), Somatic Symptom Inventory, Hospital Anxiety Depression Scale and Short Form Health Survey collected at baseline, post-treatment and 3-month follow-up. Sleep and depressive symptoms were measured by the sleep items of the PSQI (PSQI-night) and Center for Epidemiological Studies Depression Scale (excluding the sleep item) (CESD-M). Regression and path analyses were used to understand the role of daytime functioning in sleep and depressive symptoms. We found significant group and time effects on almost all daytime variables and significant group × time interactions on PSQI-day and somatic symptoms. The adjusted regression model showed that CESD-M was associated with all daytime variables. However, PSQI-night was associated only with PSQI-day. Path analyses indicated that PSQI-day bridged PSQI-night and CESD-M in a two-way direction after the I-BMS intervention. The conclusion was that, following I-BMS intervention, improvement in daytime functioning was related predominantly to improvement in depressive symptoms. Night-time sleep related only to daytime dysfunction that was specific to sleep disturbances. Therefore, 'sleep-specific daytime impairment' could be regarded as a major link from night-time sleep to depressive symptoms. More studies are required to understand the concept of 'sleep-specific daytime impairment'.

Study protocol on comparative effectiveness of mindfulness meditation and qigong on psychophysiological outcomes for patients with colorectal cancer: a randomized controlled trial.

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

The interrelationship between sleep and depression: a secondary analysis of a randomized controlled trial on mind-body-spirit intervention.

OBJECTIVES: To conduct a secondary analysis of a randomized controlled trial (RCT) that aims to understand the mediating effects embedded in a mind-body-spirit intervention for sleep and mood disturbances. METHODS: 126 adults with mild to moderate depression and subjective sleep disturbance, defined as Center for Epidemiologic Studies Depression Scale (CESD) scores from 10 to 34 and Pittsburgh Sleep Quality Index (PSQI) score > 5, participated in a waitlist-controlled RCT of an integrative mind-body-spirit intervention (I-BMS). Holistic well-being scale (HWS), a measure of the state of affliction and equanimity in mind, body and spirit, was included as a possible mediator. Data was collected at baseline and three-month follow-up. Mediation analyses were adopted to examine the pathways leading to sleep and mood improvements. RESULTS: After adjustments of baseline severities, changes in depressive symptoms partially mediated the effect of I-BMS on nighttime symptoms of insomnia (95% CI: 0.12-0.96), while exerting a full mediating effect on daytime symptoms of insomnia (95% CI: 0.14-0.64). The effect of I-BMS on mood was mediated by daytime symptoms of insomnia and spiritual orientation, but not by nighttime symptoms of insomnia (95% CI: 0.93-4.62). CONCLUSION: A bidirectional relationship was found between sleep disturbances and depressive symptoms following a mind-body-spirit intervention. The relationship between daytime symptoms and depressive symptoms was especially strong. Of the HWS variables, spiritual orientation was the only significant mediator of mood improvement following I-BMS. Our findings suggest that efforts to optimize the treatment of comorbid sleep disturbances and depression are needed, especially the treatment of daytime impairments along with sleep and mood disruptions.

Musculoskeletal profile of middle-aged Ving Tsun Chinese martial art practitioners: A cross-sectional study.

This cross-sectional exploratory study aimed to quantify and compare the axial and appendicular bone mineral density (BMD), muscle mass, and muscle strength of middle-aged practitioners of Ving Tsun (VT; a hard-style Chinese martial art) with those of nonpractitioners.Eighteen VT practitioners (mean age ±â€Šstandard deviation = 51.8 ±â€Š17.7 years; 12 men and six women) and 36 active controls (mean age ±â€Šstandard deviation = 58.7 ±â€Š11.0 years; 18 men and 18 women) participated in the study. All participants underwent a 1-day battery of musculoskeletal examinations. The BMD of the total radius, total hip, femoral neck, and lumbar spine was measured using dual-energy X-ray absorptiometry, as was the lean mass of the arm, leg, and trunk. Muscle strength of the upper and lower limbs was assessed using a Jamar dynamometer and an isokinetic dynamometer at 60°/second, respectively.VT-trained participants had a 11.5% higher total radius BMD (P = 0.023), a 17.8% higher leg lean mass (P = 0.014), a 56.4% higher isokinetic body weight-adjusted peak torque of the knee extensors (P < 0.001), a 60.8% higher isokinetic body weight-adjusted peak torque of knee flexors (P < 0.001), and a 31.4% shorter time to reach peak torque in the knee flexors (P = 0.001) than the active controls. No significant differences were found in any of the other musculoskeletal outcomes between the 2 groups (P > 0.05).Middle-aged VT practitioners displayed a higher total radius BMD and leg lean mass and better knee extensor and flexor muscular performances than their healthy active counterparts. Healthcare professionals may consider using this alternative method of training to improve the musculoskeletal health of middle-aged adults.

Adiponectin Potentially Contributes to the Antidepressive Effects of Baduanjin Qigong Exercise in Women With Chronic Fatigue Syndrome-Like Illness.

Our recent study demonstrates that adiponectin signaling plays a significant role in mediating physical exercise-exerted effects on hippocampal neurogenesis and antidepression in mice. Whether the findings can be translated to humans remains unknown. This study aimed to investigate the effects of Baduanjin Qigong exercise on adiponectin and to evaluate whether adiponectin is involved in the antidepressive effects of Qigong exercise on chronic fatigue syndrome (CFS)-like illness. This is a randomized, waitlist-controlled trial. One hundred eight female participants were randomly assigned to either Qigong exercise or waitlist groups. Sixteen 1.5-h Qigong lessons were conducted. Outcome measures were taken at three time points. Baseline adiponectin levels were negatively associated with body weight, body mass index, waist circumference, hip circumference, and waist/hip ratio in women with CFS-like illness. Compared with the waitlist control, Qigong exercise significantly reduced anxiety and depression symptoms and significantly raised plasma adiponectin levels (median = 0.8 vs. -0.1, p < 0.05). More interestingly, increases in adiponectin levels following Qigong exercise were associated with decreases in depression scores for the Qigong group (r = -0.38, p = 0.04). Moreover, adjusted linear regression analysis further identified Qigong exercise and change in adiponectin levels as the significant factors accounting for reduction of depression symptoms. Baduanjin Qigong significantly increased adiponectin levels in females with CFS-like illness. Decreases in depression symptoms were associated with increases in adiponectin levels following Qigong exercise, indicating that the potential contribution of adiponectin to Qigong exercise elicited antidepressive effects in human subjects.

Dyadic associations between psychological distress and sleep disturbance among Chinese patients with cancer and their spouses.

BACKGROUND: Patients with cancer and their spouses usually both suffer, but the dyadic effects have not been thoroughly investigated. This study examined the dyadic effects of psychological distress on sleep disturbance in Chinese couples affected by cancer. METHODS: Patients with cancer and their spouses (N = 135) participated in this study. The Hospital Anxiety and Depression Scale and Pittsburgh Sleep Quality Index were used to measure anxiety, depression, and sleep disturbance. RESULTS: There were significant patient-spouse associations on anxiety (r = 0.48, P < .01), depression (r = 0.55, P < .01), and sleep disturbance (r = 0.30, P < .01). Analyses using the actor-partner interdependence model showed that anxiety had significant actor effects, rather than partner effects, on sleep disturbance in both patients and their spouses, but depression had both actor and partner effects. In addition to providing evidence for the concordance in distress and sleep disturbance in patients with cancer and their spouses, the findings indicate a mutual influence of depression on sleep disturbance among the couples. CONCLUSIONS: Clinicians and health care providers are suggested to integrate depression management as a component of sleep therapies and involve both patients and their spouses in treatment programs.
