Cerebral Blood Flow and Brain Functional Connectivity Changes in Older Adults Participating in a Mindfulness-Based Stress Reduction Program.

There is a growing interest in the potential beneficial effects of mindfulness meditation training in protecting against age-related physical, emotional, and cognitive decline. The current prospective, single-center, single-arm study investigated if functional magnetic resonance imaging-based changes in cerebral blood flow and brain functional connectivity could be observed in 11 elderly adults (mean age 79) after participation in a Mindfulness-Based Stress Reduction (MBSR) program. The results showed significantly (p < 0.05) altered cerebral blood flow and functional connectivity in the cingulate gyrus, limbic structures, and subregions of the temporal and frontal lobes, similar to findings of other meditation-related studies in younger populations. Furthermore, these changes were also associated with significant improvements in depression symptoms. This study suggests that the MBSR program can potentially modify cerebral blood flow and connectivity in this population.

A Telephone-Adapted Mindfulness-Based Stress Reduction Program: Preliminary Effects among Healthcare Employees.

Healthcare employees often experience high stress and may benefit from accessible psychosocial interventions. In this pilot study, we explored preliminary feasibility, acceptability, and psychological effects of a telephone-based adaption of mindfulness-based stress reduction (MBSR) for healthcare employees. Eleven participants (M age = 49.9; 27.3% ethnic/racial minority) were enrolled in an eight-session group-based MBSR program adapted for telephone delivery. Feasibility was assessed using rates of program attrition and session completion; acceptability was explored qualitatively via participants' responses to an open-ended item about their program experience. Participants also completed pre-and post-program assessments on psychosocial outcomes (distress (overall distress, depression, anxiety, somatization), mindfulness, and self-compassion). We characterized mean change scores, 95% confidence intervals, and effect sizes to explore preliminary program effects. With regard to preliminary feasibility, one participant dropped out prior to the intervention; of the remaining 10 participants, 90% completed at least half (≥4) of the sessions; 70% completed at least three-quarters (≥6 sessions). Feedback reflected positive experiences and included suggestions for program delivery. Participants reported reductions in distress post-program (M difference range = -5.0 to -9.4), showing medium to large effect sizes (d range = 0.68 to 1.11). Mindfulness scores increased from pre- to post-intervention (M difference range = 1.0 to 10.4), with small-to-medium effects (d range = 0.18 to 0.55). Almost all aspects of self-compassion remained stable over time, with the exception of common humanity, which increased post-program (M difference = 2.9, CI 95% 0.5 to 5.4, d = 0.91). Preliminary findings from our small pilot trial suggest that telephone-based adaptations of MBSR may be a useful mode of delivery for healthcare employees; however, larger studies are needed to provide further evidence of feasibility, acceptability, and program effects.

Mindfulness-Based Stress Reduction in Women with Overweight or Obesity: A Randomized Clinical Trial.

OBJECTIVE: To evaluate the feasibility and cardiometabolic effects of mindfulness-based stress reduction (MBSR) in women with overweight or obesity. METHODS: Eighty-six women with BMI ≥ 25 kg/m2 were randomized to 8 weeks of MBSR or health education and followed for 16 weeks. The primary outcome was the Toronto Mindfulness Scale. Secondary outcomes included the Perceived Stress Scale-10, fasting glucose, and blood pressure. RESULTS: Compared to health education, the MBSR group demonstrated significantly improved mindfulness at 8 weeks (mean change from baseline, 4.5 vs. -1.0; P = 0.03) and significantly decreased perceived stress at 16 weeks (-3.6 vs. -1.3, P = 0.01). In the MBSR group, there were significant reductions in fasting glucose at 8 weeks (-8.9 mg/dL, P = 0.02) and at 16 weeks (-9.3 mg/dL, P = 0.02) compared to baseline. Fasting glucose did not significantly improve in the health education group. There were no significant changes in blood pressure, weight, or insulin resistance in the MBSR group. CONCLUSIONS: In women with overweight or obesity, MBSR significantly reduces stress and may have beneficial effects on glucose. Future studies demonstrating long-term cardiometabolic benefits of MBSR will be key for establishing MBSR as an effective tool in the management of obesity.

Mindfulness-based stress reduction for overweight/obese women with and without polycystic ovary syndrome: design and methods of a pilot randomized controlled trial.

INTRODUCTION: Mindfulness-based stress reduction (MBSR) may be beneficial for overweight/obese women, including women with polycystic ovary syndrome (PCOS), as it has been shown to reduce psychological distress and improve quality of life in other patient populations. Preliminary studies suggest that MBSR may also have salutary effects on blood pressure and blood glucose. This paper describes the design and methods of an ongoing pilot randomized controlled trial evaluating the feasibility and effects of MBSR in PCOS and non-PCOS women who are overweight or obese (NCT01464398). METHODS AND DESIGN: Eighty six (86) women with body mass index ≥ 25 kg/m(2), including 31 women with PCOS, have been randomized to 8 weeks of MBSR or health education control, and followed for 16 weeks. The primary outcome is mindfulness assessed with the Toronto Mindfulness Scale. Secondary outcomes include measures of blood pressure, blood glucose, quality of life, anxiety and depression. DISCUSSION: Our overall hypothesis is that MBSR will increase mindfulness and ultimately lead to favorable changes in blood pressure, blood glucose, psychological distress and quality of life in PCOS and non-PCOS women. This would support the integration of MBSR with conventional medical treatments to reduce psychological distress, cardiovascular disease and diabetes in PCOS and non-PCOS women who are overweight or obese.

An adapted mindfulness-based stress reduction program for elders in a continuing care retirement community: quantitative and qualitative results from a pilot randomized controlled trial.

The purpose of this study was to test the feasibility and effectiveness of an adapted 8-week Mindfulness-Based Stress Reduction (MBSR) program for elders in a continuing care community. This mixed-methods study used both quantitative and qualitative measures. A randomized waitlist control design was used for the quantitative aspect of the study. Thirty-nine elderly were randomized to MBSR (n = 20) or a waitlist control group (n = 19), mean age was 82 years. Both groups completed pre-post measures of health-related quality of life, acceptance and psychological flexibility, facets of mindfulness, self-compassion, and psychological distress. A subset of MBSR participants completed qualitative interviews. MBSR participants showed significantly greater improvement in acceptance and psychological flexibility and in role limitations due to physical health. In the qualitative interviews, MBSR participants reported increased awareness, less judgment, and greater self-compassion. Study results demonstrate the feasibility and potential effectiveness of an adapted MBSR program in promoting mind-body health for elders.

Enhanced psychosocial well-being following participation in a mindfulness-based stress reduction program is associated with increased natural killer cell activity.

BACKGROUND: Mindfulness-based stress reduction (MBSR) programs have consistently been shown to enhance the psychosocial well-being of participants. Given the well-established association between psychosocial factors and immunologic functioning, it has been hypothesized that enhanced psychosocial well-being among MBSR participants would be associated with corresponding changes in markers of immune activity. OBJECTIVES: The objectives of this study were to examine changes in psychosocial and immunologic measures in a heterogeneous patient sample following participation in a MBSR program. DESIGN: A single-group, pretest/post-test design was utilized. SETTING: The intervention was conducted at an academic health center. SUBJECTS: This pilot study involved 24 participants (aged 28-72 years). Inclusion criteria were as follows: > or =18 years of age, English-speaking, and no known autoimmune disorder. INTERVENTION: The intervention was an 8-week MBSR program. OUTCOME MEASURES: Distress and quality of life (QOL) measures included the Brief Symptom Inventory-18 and the Medical Outcomes Survey Short-Form Health Survey, respectively. Immunologic measures included natural killer (NK) cell cytolytic activity and C-reactive protein (CRP). RESULTS: Patients completed psychosocial assessments and provided a blood sample at baseline (pre-MBSR) and within 2 weeks post-MBSR. Significant improvements in anxiety and overall distress as well as across multiple domains of QOL were observed from baseline to post-MBSR. Reductions in anxiety and overall distress were associated with reductions in CRP. Patients who reported improvement in overall mental well-being also showed increased NK cytolytic activity from pre- to post-MBSR, whereas patients who reported no improvement in mental well-being showed no change in NK cytolytic activity. CONCLUSIONS: Positive improvement in psychologic well-being following MBSR was associated with increased NK cytolytic activity and decreased levels of CRP.

Mindfulness-based stress reduction for chronic pain conditions: variation in treatment outcomes and role of home meditation practice.

OBJECTIVE: This study compared changes in bodily pain, health-related quality of life (HRQoL), and psychological symptoms during an 8-week mindfulness-based stress reduction (MBSR) program among groups of participants with different chronic pain conditions. METHODS: From 1997-2003, a longitudinal investigation of chronic pain patients (n=133) was nested within a larger prospective cohort study of heterogeneous patients participating in MBSR at a university-based Integrative Medicine center. Measures included the Short-Form 36 Health Survey and Symptom Checklist-90-Revised. Paired t tests were used to compare pre-post changes on outcome measures. Differences in treatment effect sizes were compared as a function of chronic pain condition. Correlations were examined between outcome parameters and home meditation practice. RESULTS: Outcomes differed in significance and magnitude across common chronic pain conditions. Diagnostic subgroups of patients with arthritis, back/neck pain, or two or more comorbid pain conditions demonstrated a significant change in pain intensity and functional limitations due to pain following MBSR. Participants with arthritis showed the largest treatment effects for HRQoL and psychological distress. Patients with chronic headache/migraine experienced the smallest improvement in pain and HRQoL. Patients with fibromyalgia had the smallest improvement in psychological distress. Greater home meditation practice was associated with improvement on several outcome measures, including overall psychological distress, somatization symptoms, and self-rated health, but not pain and other quality of life scales. CONCLUSION: MBSR treatment effects on pain, HRQoL and psychological well-being vary as a function of chronic pain condition and compliance with home meditation practice.

Mindfulness-based stress reduction is associated with improved glycemic control in type 2 diabetes mellitus: a pilot study.

CONTEXT: Psychological distress is linked with impaired glycemic control among diabetics. OBJECTIVE: Estimate changes in glycemic control, weight, blood pressure, and stress-related psychological symptoms in patients with type 2 diabetes participating in a standard Mindfulness Based Stress Reduction (MBSR) program. DESIGN: Prospective, observational study. SETTING: Academic health center. PATIENTS: Adult patients with type 2 diabetes mellitus. INTERVENTIONS: Participation in MBSR program for heterogeneous patient population. Diet and exercise regimens held constant. MAIN OUTCOME MEASURES: Glycosylated hemoglobin A1c (HA1c), blood pressure, body weight, and Symptom Checklist 90-Revised (anxiety, depression, somatization, and general psychological distress scores). RESULTS: Eleven of 14 patients completed the intervention. At 1 month follow-up, HA1c was reduced by 0.48% (P = .03), and mean arterial pressure was reduced by 6 mmHg (P = .009). Body weight did not change. A decrease in measures of depression, anxiety, and general psychological distress was observed.

Mindfulness-based stress reduction lowers psychological distress in medical students.

BACKGROUND: Medical students confront significant academic, psychosocial, and existential stressors throughout their training. Mindfulness-based stress reduction (MBSR) is an educational intervention designed to improve coping skills and reduce emotional distress. PURPOSE: The purpose of this study was to examine the effectiveness of the MBSR intervention in a prospective, nonrandomized, cohort-controlled study. METHODS: Second-year students (n = 140) elected to participate in a 10-week MBSR seminar. Controls (n = 162) participated in a didactic seminar on complementary medicine. Profile of Mood States (POMS) was administered preintervention and postintervention. RESULTS: Baseline total mood disturbance (TMD) was greater in the MBSR group compared with controls (38.7 +/- 33.3 vs. 28.0 +/- 31.2; p < .01). Despite this initial difference, the MBSR group scored significantly lower in TMD at the completion of the intervention period (31.8 +/- 33.8 vs. 38.6 +/- 32.8; p < .05). Significant effects were also observed on Tension-Anxiety, Confusion-Bewilderment, Fatigue-Inertia, and Vigor-Activity subscales. CONCLUSION: MBSR may be an effective stress management intervention for medical students.
