RESUMO

Background: There is a lack of mindfulness instructors from underserved/underrepresented communities who have completed systematic mindfulness teacher-training programs to meet the growing demand for culturally responsive mindfulness training in those communities. Objectives: To investigate strategies for increasing the representation of Mindfulness-Based Stress Reduction (MBSR) teachers who serve historically underrepresented racial and ethnic groups. Methods: Conducted through 4 one-hour Zoom focus groups (n = 54; women = 74%), this study queried individuals with experience serving underrepresented racial and ethnic communities, and had mindfulness experience, on how to increase participation from underrepresented communities in mindfulness. Thematic analysis of transcripts of participant responses involved double-coding by three team members, supporting rigorous evaluation of the data. All respondents who expressed interest in participating enrolled (no dropout from study enrollment to participation in focus groups). Results: The study identified four key themes that illuminate challenges and essential adaptations for MBSR teacher training aimed at individuals serving historically underrepresented racial and ethnic groups. These themes include: (1) Cost and time commitment; (2) Trauma sensitivity; (3) Cultural Awareness; and (4) Diversity in teachers. Conclusion: Participants provided actionable recommendations poised to facilitate the expansion of MBSR into more diverse communities, emphasizing optimal benefits and effective communication of inherent healing strengths within these communities. The findings underscore the compelling interest among leaders in marginalized communities to extend the reach of MBSR through culturally responsive approaches. This involves guiding pertinent adjustments and encouraging greater involvement of underserved communities in MBSR teacher training programs.

RESUMO

Importance: Hypertension is a major cause of cardiovascular disease, and although the Dietary Approaches to Stop Hypertension (DASH) diet lowers blood pressure (BP), adherence is typically low. Mindfulness training adapted to improving health behaviors that lower BP could improve DASH adherence, in part through improved interoceptive awareness relevant to dietary consumption. Objective: To evaluate the effects of the Mindfulness-Based Blood Pressure Reduction (MB-BP) program on interoceptive awareness and DASH adherence. Design, Setting, and Participants: Parallel-group, phase 2, sequentially preregistered randomized clinical trials were conducted from June 1, 2017, to November 30, 2020. Follow-up was 6 months. Participants with elevated unattended office BP (≥120/80 mm Hg) were recruited from the population near Providence, Rhode Island. Of 348 participants assessed for eligibility, 67 did not meet inclusion criteria, 17 declined, and 63 did not enroll prior to study end date. In total, 201 participants were randomly assigned, 101 to the MB-BP program and 100 to the enhanced usual care control group, with 24 (11.9%) unavailable for follow-up. Outcome assessors and the data analyst were blinded to group allocation. Analyses were performed using intention-to-treat principles from June 1, 2022, to August 30, 2023. Interventions: The 8-week MB-BP program was adapted for elevated BP, including personalized feedback, education, and mindfulness training directed to hypertension risk factors. Both MB-BP and control groups received home BP monitoring devices with instructions and options for referral to primary care physicians. The control group also received educational brochures on controlling high BP. Main Outcomes and Measures: The primary outcome was Multidimensional Assessment of Interoceptive Awareness (MAIA) questionnaire scores (range 0-5, with higher scores indicating greater interoceptive awareness), and the secondary outcome was DASH adherence scores assessed via a 163-item Food Frequency Questionnaire (range 0-11, with higher scores indicating improved DASH adherence), all compared using regression analyses. Results: Among 201 participants, 118 (58.7%) were female, 163 (81.1%) were non-Hispanic White, and the mean (SD) age was 60.0 (12.2) years. The MB-BP program increased the MAIA score by 0.54 points (95% CI, 0.35-0.74 points; P < .001; Cohen d = 0.45) at 6 months vs control. In participants with poor baseline DASH adherence, the MB-BP program also significantly increased the DASH score by 0.62 points (95% CI, 0.13-1.11 points; P = .01; Cohen d = 0.71) at 6 months vs controls. The intervention was also associated with a 0.34-point improvement in the DASH diet score in all MB-BP participants from baseline (95% CI, 0.09-0.59 points; P = .01; Cohen d = 0.27), while the control group showed a -0.04 point change in DASH diet score from baseline to 6 months (95% CI, -0.31 to 0.24 points; P = .78; Cohen d = -0.03). Conclusions and Relevance: A mindfulness program adapted to improving health behaviors to lower BP improved interoceptive awareness and DASH adherence. The MB-BP program could support DASH dietary adherence in adults with elevated BP. Clinical Trial Registration: ClinicalTrials.gov Identifiers: NCT03859076 and NCT03256890.

RESUMO

BACKGROUND: Growing evidence suggests maternal stress contributes to the development of adverse pregnancy outcomes that are associated with cardiovascular and cardiometabolic risk in birthing persons. Mindfulness-based interventions may positively affect psychological stress in pregnancy and, in turn, reduce stress. However, few study authors have examined the effects of mindfulness-based interventions on adverse pregnancy outcomes that heighten cardiovascular risk. OBJECTIVE: The aim of this study was to appraise available literature examining the effects of mindfulness-based interventions delivered during pregnancy on adverse pregnancy outcomes associated with future cardiovascular and cardiometabolic disease risk. METHODS: In this systematic review, multiple electronic databases were searched using major keywords, including "mindfulness-based intervention," "pregnancy," "preterm delivery," "gestational diabetes," "small for gestational age," "preeclampsia," and "hypertension in pregnancy" during February 2023. RESULTS: Six studies using mindfulness-based interventions during pregnancy were included. The review indicated that these interventions were largely effective at reducing prenatal stress; however, the overall effects of interventions were mixed concerning their impact on pregnancy complications. Study authors examining the effects on gestational diabetes-related outcomes reported significant improvements in blood glucose levels, hemoglobin A1c, and oral glucose tolerance. Outcomes were mixed or inconclusive related to the effects of interventions on the incidence of preterm birth, birth of a small-for-gestational-age newborn, and preeclampsia. CONCLUSIONS: Mitigating cardiovascular and cardiometabolic risk-associated adverse pregnancy outcomes through mindfulness-based approaches may represent an emerging field of study. The few studies and limited, mixed findings synthesized in this review indicate that high-validity studies are warranted to examine the effects of mindfulness-based interventions on pregnancy complications that contribute to cardiovascular-related maternal morbidity and suboptimal life course health for diverse birthing persons.

RESUMO

Background: Hypertension is a major cause of cardiovascular disease. The Dietary Approaches to Stop Hypertension (DASH) diet lowers blood pressure (BP). However, adherence is typically low. Mindfulness training adapted to improving health behaviors that lower BP could improve DASH adherence, in part through improved interoceptive awareness relevant to dietary consumption. The primary objective of the MB-BP trial was to evaluate effects of the Mindfulness-Based Blood Pressure Reduction (MB-BP) program on interoceptive awareness. Secondary objectives assessed whether MB-BP impacts DASH adherence, and explored whether interoceptive awareness mediates DASH dietary changes. Methods: Parallel-group phase 2 randomized clinical trial conducted from June 2017-November 2020 with 6 months follow-up. Data analyst was blinded to group allocation. Participants had elevated unattended office BP (≥120/80 mmHg). We randomized 201 participants to MB-BP (n=101) or enhanced usual care control (n=100). Loss-to-follow-up was 11.9%. Outcomes were the Multidimensional Assessment of Interoceptive Awareness (MAIA; range 0-5) score, and the DASH adherence score (range 0-11) assessed via a 163-item Food Frequency Questionnaire. Results: Participants were 58.7% female, 81.1% non-Hispanic white, with mean age 59.5 years. Regression analyses demonstrated that MB-BP increased the MAIA score by 0.54 (95% CI: 0.35,0.74; p<.0001) at 6 months follow-up vs. control. MB-BP increased the DASH score by 0.62 (95% CI: 0.13,1.11; p=0.01) at 6 months vs. control, in participants with poor DASH adherence at baseline. Conclusions: A mindfulness training program adapted to improving health behaviors that lower BP improved interoceptive awareness and DASH adherence. MB-BP could support DASH dietary adherence in adults with elevated BP.

RESUMO

Background Hypertension is a leading risk factor for cardiovascular disease. Despite availability of effective lifestyle and medication treatments, blood pressure (BP) is poorly controlled in the United States. Mindfulness training may offer a novel approach to improve BP control. The objective was to evaluate the effects of Mindfulness-Based Blood Pressure Reduction (MB-BP) versus enhanced usual care control on unattended office systolic BP. Methods and Results Methods included a parallel-group phase 2 randomized clinical trial conducted from June 2017 to November 2020. Follow-up time was 6 months. Outcome assessors and data analyst were blinded to group allocation. Participants had elevated unattended office BP (≥120/80 mm Hg). We randomized 201 participants to MB-BP (n=101) or enhanced usual care control (n=100). MB-BP is a mindfulness-based program adapted for elevated BP. Loss-to-follow-up was 17.4%. The primary outcome was change in unattended office systolic BP at 6 months. A total of 201 participants (58.7% women; 81.1% non-Hispanic White race and ethnicity; mean age, 59.5 years) were randomized. Results showed that MB-BP was associated with a 5.9-mm Hg reduction (95% CI, -9.1 to -2.8 mm Hg) in systolic BP from baseline and outperformed the control group by 4.5 mm Hg at 6 months (95% CI, -9.0 to -0.1 mm Hg) in prespecified analyses. Plausible mechanisms with evidence to be impacted by MB-BP versus control were sedentary activity (-350.8 sitting min/wk [95% CI, -636.5 to -65.1] sitting min/wk), Dietary Approaches to Stop Hypertension diet (0.32 score [95% CI, -0.04 to 0.67]), and mindfulness (7.3 score [95% CI, 3.0-11.6]). Conclusions A mindfulness-based program adapted for individuals with elevated BP showed clinically relevant reductions in systolic BP compared with enhanced usual care. Mindfulness training may be a useful approach to improve BP. Registration URL: https://www.clinicaltrials.gov; Unique identifiers: NCT03256890 and NCT03859076.

RESUMO

This paper provides a framework for understanding why, when and how to adapt mindfulness-based programs (MBPs) to specific populations and contexts, based on research that developed and adapted multiple MBPs. In doing so, we hope to support teachers, researchers and innovators who are considering adapting an MBP to ensure that changes made are necessary, acceptable, effective, cost-effective, and implementable. Specific questions for reflection are provided such as (1) Why is an adaptation needed? (2) Does the theoretical premise underpinning mainstream MBPs extend to the population you are considering? (3) Do the benefits of the proposed adaptation outweigh the time and costs involved to all in research and implementation? (4) Is there already an evidenced-based approach to address this issue in the population or context? Fundamental knowledge that is important for the adaptation team to have includes the following: (1) essential ingredients of MBPs, (2) etiology of the target health outcome, (3) existing interventions that work for the health outcome, population, and context, (4) delivery systems and settings, and (5) culture, values, and communication patterns of the target population. A series of steps to follow for adaptations is provided, as are case examples. Adapting MBPs happens not only by researchers, but also by MBP teachers and developers, who endeavor to best serve the populations and contexts they work within. We hope that these recommendations for best practice provide a practical framework for skilfully understanding why, when, and how to adapt MBPs; and that this careful approach to adaptation maximizes MBP safety and efficacy.

RESUMO

Though it is often taken as a truism that communication contributes to organizational productivity, there are surprisingly few empirical studies documenting a relationship between observable interaction and productivity. This is because comprehensive, direct observation of communication in organizational settings is notoriously difficult. In this paper, we report a method for extracting network and speech characteristics data from audio recordings of participants talking with each other in real time. We use this method to analyze communication and productivity data from seventy-nine employees working within a software engineering organization who had their speech recorded during working hours for a period of approximately 3 years. From the speech data, we infer when any two individuals are talking to each other and use this information to construct a communication graph for the organization for each week. We use the spectral and temporal characteristics of the produced speech and the structure of the resultant communication graphs to predict the productivity of the group, as measured by the number of lines of code produced. The results indicate that the most important speech and network features for predicting productivity include those that measure the number of unique people interacting within the organization, the frequency of interactions, and the topology of the communication network.

RESUMO

OBJECTIVES: . Older African Americans have a significantly higher risk than older white Americans for cognitive decline and other health problems. Much of this may be due to the unique stressors, both historically and in-the-moment, that African Americans face in contrast to whites, such as gentrification and health disparities. Gender further exacerbates this effect. This study aims to understand stressors unique to older African American women, as well as coping strengths that have emerged organically over time for use in tailoring stress-reduction mindfulness classes in this community DESIGN AND SETTING: . A four-week mindfulness training class adapted from mindfulness-based stress reduction (MBSR) was implemented in a historically black, gentrifying neighborhood in Portland, Oregon with 10 older African American women aged 50-89. MAIN OUTCOME MEASURES: . Focus groups discussed stressors, coping, responses to mindfulness classes, and preferences to better reflect older African American cultural values and norms. RESULTS: . Stressors reflected participants' intersectionality as older black women, including neighborhood and workplace race-based microagressions, and gentrification-related cultural and generational incongruences. Coping strategies included self-care, remembering core-self amidst stress, and drawing strength from family and faith. Participants found mindfulness classes appropriate for addressing stress and felt that classes provided a forum for connecting on issues of race and community. CONCLUSION: . Tailoring classes to older African American women should consider integrating biblical teachings, African American instructors who understand socio-historical contexts of older black women's stressors and strengths, and time for group-reflection to support community building.

RESUMO

Despite the interest in mindfulness over the past 20 years, studies have only recently begun to examine mindfulness in older adults. The primary aim of this study was to evaluate pretreatment to post-treatment change in negative affect variability (NAV) following a mindfulness training among 134 mildly stressed, middle-aged to older adults. The secondary aim was to assess if the effects of mindfulness training on NAV would be partially explained by pretreatment to post-treatment reductions in perceived stress, a trend that would be congruent with several stress models. In this randomized control trial, participants were assigned to either a 6-week mindfulness meditation training programme or to a wait list control. Ecological momentary assessment, a data capturing technique that queries about present moment experiences in real time, captured NAV. Mixed-model ANOVAs and a path analysis were conducted. Participants in the mindfulness meditation training significantly reduced NAV when compared with wait list control participants. Further, there was a significant indirect group effect on reductions in NAV through change in perceived stress. Few studies have tested mechanisms of action, which connect changes that occur during mindfulness training with psychological outcomes in older adults. Understanding the mechanisms by which mindfulness enhances well-being may optimize interventions.

RESUMO

As many health disparities in American minority communities (AMCs) are stress-related, there has been an increased interest in the development of mindfulness programs as potential stress reduction measures in these communities. However, the bulk of the extant literature on mindfulness research and mindfulness interventions is based upon experiences with the larger White community. The intent of this commentary is to share a framework that includes key cultural considerations for conducting research and developing culturally-salient mindfulness programs with AMCs. We build on our experiences and the experiences of other researchers who have explored mindfulness in African and Native American communities; in particular, we examine issues around community outreach with an emphatic gesture toward emphasizing protection of AMCs and their participants. Discussed are considerations with respect to attitudinal foundations in mindfulness-based research and program development with these communities. However, the overall message of this paper is not to provide a "to-do" list of research steps, but to rather, encourage researchers to turn inward and consider the development of skillful characteristics that will increase the likelihood of a successful research venture while also protecting the cultural traditions of the AMC of interest.

RESUMO

Context • The benefits of a mindfulness meditation (MM) intervention are most often evidenced by improvements in self-rated stress and mental health. Given the physiological complexity of the psychological stress system, it is likely that some people benefit significantly, whereas others do not. Clinicians and researchers could benefit from further exploration to determine which baseline factors can predict clinically significant improvements from MM. Objectives • The study intended to determine (1) whether the baseline measures for participants who significantly benefitted from MM training were different from the baseline measures of participants who did not, and (2) whether a classification analysis using a decision-tree, machine-learning approach could be useful in predicting which individuals would be most likely to improve. Design • The research team performed a secondary analysis of a previously completed randomized, controlled clinical trial. Setting • The study occurred at the Oregon Health & Science University (Portland, OR, USA) and in participants' homes. Participants • Participants were 134 stressed, generally healthy adults from the metropolitan area of Portland, Oregon, who were 50 to 85 y old. Intervention • Participants were randomly assigned either to a 6-wk MM intervention group or to a waitlist control group, who received the same MM intervention after the waitlist period. Outcome Measures • Outcome measures were assessed at baseline and at 2-mo follow-up intervals. A responder was defined as someone who demonstrated a moderate, clinically significant improvement on the mental health component (MHC) of the short-form health-related quality of life (SF-36) (ie, a change ≥4). The MHC had demonstrated the greatest effect size in the primary analysis of the previously mentioned randomized, controlled clinical trial. Potential predictors were demographic information and baseline measures related to stress and affect. Univariate statistical analyses were performed to compare the values of predictors in the responder and nonresponder groups. In addition, predictors were chosen for a classification analysis using a decision tree approach. Results • Of the 134 original participants, 121 completed the MM intervention. As defined previously, 61 were responders and 60 were nonresponders. Analyses of the baseline measures demonstrated significant differences between the 2 groups in several measures: (1) the positive and negative affect schedule negative subscale (PANAS-neg), (2) the SF-36-MHC, and (3) the SF-36 energy/fatigue, with clinically worse scores being associated with greater likelihood of being a responder. Disappointingly, the decision-tree analyses were unable to achieve a classification rate of better than 65%. Conclusions • The differences in predictor variables between responders and nonresponders to an MM intervention suggested that those with worse mental health at baseline were more likely to improve. Decision-tree analysis was unable to usefully predict who would respond to the intervention.

RESUMO

Much of the extant cortisol awakening response (CAR) literature posits that CAR is an anticipatory response to perceived demands later that same day. However, expanding and switching the temporal order of cortisol and psychosocial influences may motivate more flexible approaches to understanding the dynamic relationship between mind and body, including cumulative strain on the HPA axis. This study was novel because we used two models to explore the effects of one day's emotion regulation and cortisol levels on cortisol and CAR the following day in 100 mildly stressed adults aged 50-81 years old, which contrasts with the more common CAR-anticipatory-response design. In the first model, High negative-affect-variation on day 1 predicted a higher risk of having a flat CAR the next day, relative to the moderate-affect-variation group (RR = 10.10, p < .05). In the second model, higher bedtime cortisol on day 1 was positively associated with waking cortisol (ß = .293, p < .01) and flatter CAR slopes on day 2 (ß = -.422, p < .001). These results show that morning cortisol intercepts and slopes may be associated with previous days' affect variability and levels of bedtime cortisol. These results also suggest that anticipation of demands may extend to the previous day, rather than just the morning of the demand, indicating a broader temporal framework for the study of CAR.

RESUMO

This study aimed to examine reciprocal relations between cholesterol and depression. We assessed cholesterol and depressive symptoms twice over a 3-year interval, using 842 men from the Veterans Affairs Normative Aging Study (M = 64, standard deviation = 8). Because depressive symptoms were skewed, we used zero-inflated Poisson analyses. Cross-lagged models showed that cholesterol levels at T1 predicted the existence of depressive symptoms at T2, covarying T1 depressive symptoms, age, smoking status, body mass index, and medications. Depressive symptoms at T1 did not predict cholesterol at T2. Low cholesterol levels may be risk factors for development of depressive symptoms in late life.
