Effects of mindful physical activity on perceived exercise exertion and other physiological and psychological responses: results from a within-subjects, counter-balanced study.

Background: Most adults are insufficiently active. Mindfulness training may increase moderate to vigorous physical activity (MVPA) adoption and adherence. However, physiological and psychological factors underlying these effects are not well understood. This study examined the effects of an acute bout of MVPA, mindfulness training, and combined MVPA and mindfulness training on physiological and psychological outcomes. Methods: Healthy adults (N = 29, Mage = 28.6) completed 20-min counterbalanced conditions: (a) mindfulness training (MIND); (b) moderate intensity walking (PA), and (c) moderate intensity walking while listening to MVPA-specific guided mindfulness training (PAMIND). Heart rate (HR), Rating of Perceived Exertion (RPE), Feeling Scale (FS) and Blood Pressure (BP) were measured at rest, at regular intervals during each condition, and post-condition. Mindfulness, state anxiety, and self-efficacy were assessed pre- and post-condition. Results: Average and peak HR, systolic BP (SBP), and RPE were significantly higher, and average and peak FS were significantly lower during the PA and PAMIND conditions compared to MIND (p < 0.001). Average RPE was significantly higher for PA compared to PAMIND (p < 0.001). Heart rate, feeling scale, body and mental events mindfulness, and self-efficacy for walking increased from pre to post (all p's < 0.001) for all conditions. Time by condition interactions were significant for change in heart rate, mental events mindfulness, and state anxiety from pre- to post-condition. Conclusion: The physiological response to MVPA and PAMIND were similar. However, RPE was rated lower in the PAMIND condition, which could have implications for MVPA adoption and maintenance. Future work should further explore RPE combining MVPA and mindfulness training.

Mindfulness-based stress reduction for men on active surveillance for prostate cancer and their spouses: Design and methodology of a randomized controlled trial.

BACKGROUND: Although active surveillance (AS) is an increasingly adopted treatment paradigm for management of very low risk prostate cancer, many men and their partners face a variety of AS-related psychosocial stressors. Stressors may include anxiety and fear of progression, which may negatively affect short- and long-term psychosocial adjustment and influence early withdrawal from AS in order to seek definitive therapies such as surgery or radiation. Here we describe the protocol for an NCI-funded trial, which seeks to examine the efficacy of mindfulness training compared with a time/attention-matched health promotion control condition in a geographically generalizable sample of men on AS and their spouses. METHODS: Using a randomized, controlled, partially double-blinded study design, this study involves the delivery of 8 weeks of standardized mindfulness training (MBSR; mindfulness-based stress reduction) and patient reported outcomes over a 12-month period (proposed enrollment of 80 men on AS and spouses), compared with a health promotion control (proposed enrollment of 80 men on AS and spouses) that has been matched for time and attention. Baseline (T1) measures (e.g., anxiety, fear of progression, quality of life) are administered just prior to randomization to the two study arms, followed by repeated assessments at 2 months (T2), 6 months (T3) and 12 months (T4). CONCLUSION: This study has the potential to offer men and their partners on AS with important educational and self-regulatory skills to better cope and adjust with known stressors related to being placed on this protocol.

Preliminary Effects of Mindfulness Training on Inflammatory Markers and Blood Pressure in Young Adult Survivors of Cancer: Secondary Analysis of a Pilot Randomized Controlled Trial.

BACKGROUND: This was a secondary analysis of a pilot randomized controlled trial (RCT) of mindfulness-based stress reduction (MBSR) among young adult (YA) survivors of cancer, which showed preliminary evidence for improving psychosocial outcomes. Secondary outcomes assessed were the feasibility of collecting biological data from YAs and preliminary effects of MBSR on markers of inflammation and cardiovascular function. METHOD: Participants were randomized to 8-week MBSR or a waitlist control condition. Participants provided whole blood spot samples for analysis of C-reactive protein (CRP) and interleukin (IL)-6 as well as blood pressure data in-person at baseline and 16-week follow-up. Feasibility was assessed with rates of providing biological data. Linear mixed effects modeling was used to evaluate preliminary effects of MBSR on inflammatory markers and blood pressure over time. RESULTS: Of 126 total participants enrolled, 77% provided biological data at baseline (n = 48/67 MBSR, n = 49/59 control). At 16 weeks, 97% of the 76 retained participants provided follow-up biological data (n = 34/35 MBSR, n = 40/41 control). Relative to the control group, MBSR was associated with decreased systolic blood pressure (p = 0.042, effect sizes (ES) = 0.45) and decreased diastolic blood pressure (p = 0.017, ES = 0.64). There were no changes in CRP or IL-6. CONCLUSION: This was the first study to explore the feasibility of collecting biological data from YA survivors of cancer and assess preliminary effects of MBSR on inflammatory and cardiovascular markers in an RCT. Minimally invasive biological data collection methods were feasible. Results provide preliminary evidence for the role of MBSR in improving cardiovascular outcomes in this population, and results should be replicated.

Consider the Source: Examining Attrition Rates, Response Rates, and Preliminary Effects of eHealth Mindfulness Messages and Delivery Framing in a Randomized Trial with Young Adult Cancer Survivors.

Purpose: Young adults with cancer often experience stress, depression, and anxiety. Mindfulness meditation is an effective intervention for these outcomes, and maintenance support may be needed for long-term improvements. eHealth technologies provide a promising delivery strategy for maintenance interventions. Methods: Following an 8-week mindfulness-based stress reduction (MBSR) course, 62 young adult cancer survivors were randomized to 8 weeks of instructor-framed messages, peer-framed messages, or no messages. On average, participants were 33.6 years old. The majority of participants were college-educated Caucasian females. We examined attrition rates between participants who received messages and those who did not, and compared response rates from different perceived sources. In addition, we evaluated the preliminary effects of eHealth support on mindfulness and associated outcomes. Results: No significant differences in attrition or message response rates across groups were observed. Repeated measures models revealed significant group by time interactions on perceived stress, anxiety, and depression. There were no differences between the groups that received eHealth messages and the group that did not. There was a significant difference in anxiety symptoms from post-MBSR to post-messaging between messaging groups. Individuals who received instructor-framed messages reported increased symptoms of anxiety over time. Conclusion: Attrition and response rates did not differ across groups, suggesting that eHealth may be a feasible strategy for providing maintenance support. However, further evaluation of feasibility, acceptability, and optimal content and dose of such an intervention is needed. Additionally, young adult cancer survivors may be more likely to benefit from eHealth interventions that are not delivered by authority figures.

A randomized pilot study of mindfulness-based stress reduction in a young adult cancer sample: Feasibility, acceptability, and changes in patient reported outcomes.

BACKGROUND: The primary purpose of this study was to examine the feasibility and acceptability of participation in a randomized waitlist-controlled intervention of mindfulness-based stress reduction (MBSR) in a young adult cancer sample. A secondary aim was to examine patterns of change in patient reported outcomes (PROs) of physical, social, and emotional functioning. METHODS: Participants were enrolled at a large Midwestern comprehensive cancer center and randomized to MBSR or a waitlist control. Feasibility and acceptability were examined through enrollment metrics and a survey. PROs were gathered at baseline, 8-weeks, and 16-weeks. Descriptive statistics and mixed models were used in analyses. RESULTS: Of 597 eligible participants, 151 (26.5%) consented from which 126 (83.4%) completed baseline measures. Sixty-seven participants were randomized to MBSR, and 59 to the waitlist. Immediately following MBSR, the majority of respondents (72%-78%) reported their experience with mindfulness was very logical and useful to increasing their wellbeing. Compared to waitlist members, MBSR participant's scores on PROs improved in expected directions. CONCLUSIONS: Our findings suggest that recruitment for an intensive, in-person, multi-week supportive intervention can be challenging with young adults with cancer, similar to other cancer survivor populations; however once enrolled, feasibility and acceptability of MBSR was supported. Further, initial evidence on the role of MBSR on short-term changes in select PROs with this population was also demonstrated.
