Mechanisms of mindfulness in patients with migraine: Results of a qualitative study.

OBJECTIVE: To understand the mechanisms of mindfulness' impact on migraine. BACKGROUND: Promising mindfulness research demonstrates potential benefit in migraine, but no data-driven model exists from the lived experiences of patients that explains the mechanisms of mindfulness in migraine. METHODS: Semi-structured qualitative interviews were conducted with adults with migraine who participated in two mindfulness-based stress reduction (MBSR) clinical trials (n = 43). Interviews were audio-recorded, transcribed, and summarized into a framework matrix with development of a master codebook. Constructivist grounded theory approach was used to identify themes/subthemes. RESULTS: Participants who learned mindfulness techniques through MBSR experienced altered pain perception, altered response to migraine attacks and disease, increased awareness of external and internal experiences, improved overall well-being, and group benefits. Mindfulness resulted in earlier stress-body awareness and increased interoceptive awareness resulting in earlier attack recognition, leading to earlier and more effective management. Interictal factors of self-blame, guilt, and stigma decreased while migraine acceptance, hope, empowerment, self-efficacy, and self-compassion increased. Improved emotion regulation resulted in decreased fear of migraine, pain catastrophizing, anticipatory anxiety, and pain reactivity. Although taught as prevention, mindfulness was used both acutely and prophylactically. We created a conceptual model hypothesizing that MBSR skills led to an infusion of mindfulness in daily life, resulting in altered pain perception and experience, ultimately leading to improvement in overall well-being, which may positively feed back to the infusion of mindfulness in daily life. The therapeutic benefit of learning mindfulness in a group setting may moderate these effects. CONCLUSIONS: This study identified several new potential mechanisms of mindfulness' effect on migraine. After learning MBSR skills, participants reported altered pain and migraine perception and experiences. Increased stress-body and interoceptive awareness resulted in earlier migraine awareness and treatment. Mindfulness may target important interictal factors that affect disease burden such as fear of migraine, pain catastrophizing, and anticipatory anxiety. This is the first data-driven study to help elucidate the mechanisms of mindfulness on migraine from patient voices and can help direct future research endeavors.

Packaged Foods Labeled as Organic Have a More Healthful Profile Than Their Conventional Counterparts, According to Analysis of Products Sold in the U.S. in 2019-2020.

The organic food market's recent rapid global growth reflects the public's interest in buying certified organic foods, including packaged products. Our analysis shows that packaged foods containing fewer ingredients associated with negative public health outcomes are more likely to be labeled organic. Previous studies comparing organic and conventional foods focused primarily on nutrient composition. We expanded this research by additionally examining ingredient characteristics, including processing and functional use. Our dataset included nutrition and ingredient data for 8240 organic and 72,205 conventional food products sold in the U.S. from 2019 to 2020. Compared to conventional foods, organic foods in this dataset had lower total sugar, added sugar, saturated fat and sodium content. Using a mixed effects logistic regression, we found that likelihood of classification as organic increased as sodium content, added sugar content and the number of ultra-processed ingredients and cosmetic additives on the product label decreased. Products containing no trans-fat ingredients were more likely to be labeled organic. A product was more likely to be classified "organic" the more potassium it contained. These features of organic foods sold in the U.S. are significant because lower dietary ingestion of ultra-processed foods, added sugar, sodium and trans-fats is associated with improved public health outcomes.

Online Mindfulness May Target Psychological Distress and Mental Health during COVID-19.

BACKGROUND: The COVID-19 pandemic has dramatically affected mental health, creating an urgent need for convenient and safe interventions to improve well-being. Online mindfulness interventions show promise for improving depression, anxiety, and general well-being. OBJECTIVE: To assess: 1) the impact of online mindfulness on psychological distress, 2) altruistic efforts, and 3) the quantity, quality, and availability of online mindfulness resources during the COVID-19 pandemic. METHODS: 233 participants (203 U.S.; 20 international; 10 unknown) participated in this prospective, single-arm, non-randomized clinical trial of a single online mindfulness meditation session with pre- and post-surveys. MAIN OUTCOME MEASURES: (a) Mindfulness session helpfulness, online platform effectiveness, and immediate pre- to post-session changes in momentary stress, anxiety, and COVID-19 concern; (b) qualitative themes representing how people are helping others during the pandemic; (c) absolute changes in quantity of mindfulness-oriented web content and free online mindfulness resource availability from May to August 2020. RESULTS: Most participants felt the online mindfulness session was helpful and the electronic platform effective for practicing mindfulness (89%, 95% CI: [82 to 93%]), with decreased momentary anxiety (76%; 95% CI: [69 to 83%]), stress (80%; [72 to 86%]), and COVID-19 concern (55%; [46 to 63%]), (p < 0.001 for each measure). Participants reported helping others in a variety of ways during the pandemic, including following public health guidelines, conducting acts of service and connection, and helping oneself in hopes of helping others. "Mindfulness + COVID" search results increased by 52% from May to August 2020. Most (73%) Academic Consortium for Integrative Medicine and Health member websites offer free online mindfulness resources. CONCLUSIONS: Virtual mindfulness is an increasingly accessible intervention available world-wide that may reduce psychological distress during this isolating public health crisis. Kindness and altruism are being demonstrated during the pandemic. The consolidated online mindfulness resources provided may help guide clinicians and patients.

Effectiveness of Mindfulness Meditation vs Headache Education for Adults With Migraine: A Randomized Clinical Trial.

Importance: Migraine is the second leading cause of disability worldwide. Most patients with migraine discontinue medications due to inefficacy or adverse effects. Mindfulness-based stress reduction (MBSR) may provide benefit. Objective: To determine if MBSR improves migraine outcomes and affective/cognitive processes compared with headache education. Design, Setting, and Participants: This randomized clinical trial of MBSR vs headache education included 89 adults who experienced between 4 and 20 migraine days per month. There was blinding of participants (to active vs comparator group assignments) and principal investigators/data analysts (to group assignment). Interventions: Participants underwent MBSR (standardized training in mindfulness/yoga) or headache education (migraine information) delivered in groups that met for 2 hours each week for 8 weeks. Main Outcomes and Measures: The primary outcome was change in migraine day frequency (baseline to 12 weeks). Secondary outcomes were changes in disability, quality of life, self-efficacy, pain catastrophizing, depression scores, and experimentally induced pain intensity and unpleasantness (baseline to 12, 24, and 36 weeks). Results: Most participants were female (n = 82, 92%), with a mean (SD) age of 43.9 (13.0) years, and had a mean (SD) of 7.3 (2.7) migraine days per month and high disability (Headache Impact Test-6: 63.5 [5.7]), attended class (median attendance, 7 of 8 classes), and followed up through 36 weeks (33 of 45 [73%] of the MBSR group and 32 of 44 [73%] of the headache education group). Participants in both groups had fewer migraine days at 12 weeks (MBSR: -1.6 migraine days per month; 95% CI, -0.7 to -2.5; headache education: -2.0 migraine days per month; 95% CI, -1.1 to -2.9), without group differences (P = .50). Compared with those who participated in headache education, those who participated in MBSR had improvements from baseline at all follow-up time points (reported in terms of point estimates of effect differences between groups) on measures of disability (5.92; 95% CI, 2.8-9.0; P < .001), quality of life (5.1; 95% CI, 1.2-8.9; P = .01), self-efficacy (8.2; 95% CI, 0.3-16.1; P = .04), pain catastrophizing (5.8; 95% CI, 2.9-8.8; P < .001), depression scores (1.6; 95% CI, 0.4-2.7; P = .008), and decreased experimentally induced pain intensity and unpleasantness (MBSR group: 36.3% [95% CI, 12.3% to 60.3%] decrease in intensity and 30.4% [95% CI, 9.9% to 49.4%] decrease in unpleasantness; headache education group: 13.5% [95% CI, -9.9% to 36.8%] increase in intensity and an 11.2% [95% CI, -8.9% to 31.2%] increase in unpleasantness; P = .004 for intensity and .005 for unpleasantness, at 36 weeks). One reported adverse event was deemed unrelated to study protocol. Conclusions and Relevance: Mindfulness-based stress reduction did not improve migraine frequency more than headache education, as both groups had similar decreases; however, MBSR improved disability, quality of life, self-efficacy, pain catastrophizing, and depression out to 36 weeks, with decreased experimentally induced pain suggesting a potential shift in pain appraisal. In conclusion, MBSR may help treat total migraine burden, but a larger, more definitive study is needed to further investigate these results.
