Botanical Dietary Supplement Use among Hispanic/Latino Adults in the Hispanic Community Health Study/Study of Latinos: Comparison of a Diet- vs. Medication-based Survey

Botanical supplement use is common in the United States, but its assessment is difficult among Hispanics/Latinos. This report documents the prevalence of botanical and non-vitamin non-mineral (NVNM) supplement use over a 30-day recall period in a sample of Hispanics/Latinos in the US as measured with two instruments. Dietary supplement assessment in the Hispanic Community Health Study/Study of Latinos included both a medication inventory and a nutrition-based dietary supplement interview, enabling a comparison of instruments across supplement categories. Additional supplements were captured from 24-hour dietary recalls. In addition, characteristics of botanical supplement users and their motivations for use were explored. The prevalence of dietary supplement use was substantially higher as measured in the dietary supplement interview as compared to the medication inventory: for total dietary supplements (40 vs. 26%, respectively), for NVNM supplements (25 vs. 13%), and botanicals (9 vs. 4%). Concordance between the two measures was fair-moderate by Cohen's Kappa (0.28 - 0.56). Estimates were sensitive to inclusion of botanical teas captured exclusively from 24-hour dietary recalls with increases in botanical supplement prevalence from 7 to 15% with their addition. After vitamins and minerals, the most prevalent supplement ingredients consumed were omega-3 fatty acids (9.7%), lutein (9.6%), and lycopene (10.5%). The prevalence of botanical supplement use varied across Hispanic/Latino background. Individuals with a self-reported Mexican, Central or South American background were more likely to use botanicals than individuals with a Dominican, Cuban, or Puerto Rican background. Other characteristics associated with botanical supplement use included age, income, and adoption of healthy lifestyle behaviors. The association of education with botanical supplement use was stronger for more rather than less acculturated individuals. Motivations for supplement use included treatment/prevention of health conditions and appearance enhancements. Botanical use prevalence varied by Hispanic/Latino background, but characteristics of botanical supplement users across backgrounds were similar to those in the general US population as were the types of botanical supplements captured. Results suggest that drivers of commercial botanical supplement consumption may not differ between Hispanics/Latinos and the non-Hispanic white population and indicate an interest in self-improvement. Clearly needed are better dietary supplement assessment strategies and standardization of categorization.Doctor of Philosoph

Patterns of Variation in Botanical Supplement Use among Hispanics and Latinos in the United States

Background: The prevalence of botanical supplement use among Hispanics/Latinos in the United States varies widely, thwarting efforts to understand patterns of use in these rapidly growing populations. In this systematic review of the literature, we present an analysis of patterns of botanical supplement use across available studies including Hispanics/Latinos in the United States, 1998-2011. Methods: Search strategies included CINAHL, EMBASE, Global Health, CAB Abstracts, AMED and Medline resulting in 33 studies reporting botanical supplement prevalence among Hispanic/Latino adults, limiting studies to those with similar outcomes and Hispanic/Latino sample ≥1%. Results: Median prevalence of botanical supplement use among Hispanics/Latinos varied from 12% for ≤30 days of use to 27% for 6-12 months of use and 45% for 2+ years of use. Variation in prevalence of botanical use among Hispanics/Latinos was largely dependent on study design factors, particularly sampling strategy and target population. Patterns associated with higher median prevalence included regional (42%, 95% CI: 35, 57%) vs. national (15%; 8, 22%) samples, convenience (45%; 35, 63%) vs. probability sampling (21%; 10, 42%), and majority Hispanic/Latino (45%; 32, 67%) vs. majority non-Hispanic/ Latino (21%; 15, 42%) samples. Studies targeting Hispanic/Latino populations with botanical assessments specific to these populations resulted in higher prevalence estimates (49% vs. 18%). The most common botanicals reported by Hispanics/ Latinos across studies were chamomile, aloe, and garlic. Conclusions: Although studies with probability sampling are less affected by selection bias, most target the general US population and exclude botanical supplements common among Hispanic/Latino populations. Improved estimates of botanical supplement use among Hispanics/Latinos require culturally-relevant assessment instruments and strategies. Assessments of botanical supplement use in other ethnic populations, e.g., among immigrants from Asian countries, are also likely to suffer from information bias

Are Formal and Informal Home Mindfulness Practice Quantities Associated With Outcomes? Results From a Pilot Study of a Four-Week Mindfulness Intervention for Chronic Pain Management

Background The association between home mindfulness practice quantity in standard length mindfulness-based interventions (MBIs) and chronic pain outcomes is variable. Few studies focus on abbreviated MBIs (< 8 weeks) and distinguish between formal guided practices and informal practices in daily life. Objectives To characterize home mindfulness practice and explore associations between home practice quantity and pre-to-post-outcome changes after an MBI for chronic pain. Methods In this single-arm study, 21 adults with chronic pain (mean age = 54 years, 81% White, mean pain duration = 7 years) completed an MBI with four weekly group sessions. Pre and post self-report measures of pain intensity/interference, physical function, depression, anxiety, positive affect, sleep disturbance (all PROMIS measures), and pain acceptance, catastrophizing, perceived stress and mindfulness were completed, along with daily surveys of formal (mindfulness of breath, body scan) and informal (breathing space, mindfulness of daily activities) practice. Bivariate correlations and multivariable regression models were used to assess the association between days and minutes of practice and change in outcomes. Results On average, formal practice was completed on 4.3 days per week and 13.5 minutes per day. Informal practice was completed on 3.5 days per week and 8.6 minutes per day. Formal practice was not significantly correlated with outcomes (Spearman’s ρ = |.01|-|.32|), whereas informal practice was correlated with multiple outcomes (ρ = |.04|-|.66|). Number of days practiced informally was associated with improved pain interference, physical function, sleep disturbance, and catastrophizing (p’s ≤ .05). Number of minutes practiced informally was associated with improved pain interference, anxiety, positive affect, and catastrophizing (p’s ≤ .05). Conclusion Informal home practice quantity, but not formal practice quantity, is associated with improved outcomes during an abbreviated MBI for chronic pain. For these MBIs, it is important to evaluate the distinct roles of formal and informal practice.ClinicalTrials.gov RegistrationNCT03495856

Craniosacral therapy for migraine: Protocol development for an exploratory controlled clinical trial

Abstract Background Migraine affects approximately 20% of the population. Conventional care for migraine is suboptimal; overuse of medications for the treatment of episodic migraines is a risk factor for developing chronic daily headache. The study of non-pharmaceutical approaches for prevention of migraine headaches is therefore warranted. Craniosacral therapy (CST) is a popular non-pharmacological approach to the treatment or prevention of migraine headaches for which there is limited evidence of safety and efficacy. In this paper, we describe an ongoing feasibility study to assess the safety and efficacy of CST in the treatment of migraine, using a rigorous and innovative randomized controlled study design involving low-strength static magnets (LSSM) as an attention control intervention. Methods The trial is designed to test the hypothesis that, compared to those receiving usual care plus a treatment with low-strength static magnets (attention-control complementary therapy), subjects receiving usual medical care plus CST will demonstrate significant improvement in: quality-of-life as measured by the Headache Impact Test (HIT-6); reduced frequency of migraine; and a perception of clinical benefit. Criteria for inclusion are either gender, age > 11, English or Spanish speaking, meeting the International Classification of Headache Disorders (ICHD) criteria for migraine with or without aura, a headache frequency of 5 to 15 per month over at least two years. After an 8 week baseline phase, eligible subjects are randomized to either CST or an attention control intervention, low strength static magnets (LSSM). To evaluate possible therapist bias, videotaped encounters are analyzed to assess for any systematic group differences in interactions with subjects. Results 169 individuals have been screened for eligibility, of which 109 were eligible for the study. Five did not qualify during the baseline phase because of inadequate headache frequency. Nineteen have withdrawn from the study after giving consent. Conclusion This report endorses the feasibility of undertaking a rigorous randomized clinical trial of CST for migraine using a standardized CST protocol and an innovative control protocol developed for the study. Subjects are able and willing to complete detailed headache diaries during an 8-week baseline period, with few dropouts during the study period, indicating the acceptability of both interventions.

Does Self-Compassion Protect Adolescents from Stress?

The aim of this study was to determine whether adolescents who were high in self-compassion self-reported different levels of emotional wellbeing than adolescents who were low in self-compassion, and to determine whether those high in self-compassion responded differently under a lab social stressor than those low in self-compassion. In a lab setting, participants (age 13–18; n = 28) completed the Trier Social Stress Test (TSST) and physiological stress was assessed via salivary cortisol, heart rate, blood pressure, and heart rate variability at baseline, during the TSST, and during recovery. After completing the lab protocol, an email was sent to participants that provided a link to an online survey which was composed of emotional wellbeing measures including perceived stress, life satisfaction, positive and negative affect. After conducting repeated measure ANOVAS to determine that the TSST induced a significant stress response, the sample was split at the median of self-compassion. T tests were conducted to determine meaningful differences (Hedges’ g > .20) between the groups. Findings indicated that those in the high self-compassion group (≥the median) self-reported greater emotional wellbeing than those in the low self-compassion group (<the median). Overall, those in the high self-compassion group also had a lower physiologic stress response when exposed to the TSST than those in the low self-compassion group. Regression analyses were also conducted; baseline self-compassion predicted self-reported emotional wellbeing, but did not predict physiological response to the TSST. Findings support the potential buffering effect that self-compassion may have in protecting adolescents from social stressors; yet more research needs to be conducted in larger samples to confirm and replicate these findings

Weathering the seasons of cancer survivorship: mind-body therapy use and reported reasons and outcomes by stages of cancer survivorship

Mind-body therapies (MBT), a subset of complementary and alternative medicine (CAM), are used by cancer survivors to manage symptoms related to their cancer experience. MBT use may differ by cancer survivorship stage (i.e., acute, short-term, long-term) because each stage presents varying intensities of medical activities, associated emotions, and treatment effects. We examined the relationship between MBT use and survivorship stage (acute: 5 years since diagnosis) using the CAM supplement of the 2012 National Health Interview Survey. We also examined reported reasons for and outcomes of MBT use and frequency of MBT types

Low-n-6 and low-n-6 plus high-n-3 diets for use in clinical research

Few trials have evaluated the metabolic effects and health outcomes of lowering dietary n-6 PUFA. The objectives of the present paper were (1) to report the methods employed to lower dietary n-6 PUFA, while either increasing or maintaining n-3 PUFA intake and (2) to validate our methods with 24 h recalls and erythrocyte fatty acid analyses. A total of sixty-seven subjects were randomised to either (1) an average-n-3 PUFA, low-n-6 PUFA (L6) intervention designed to lower linoleic acid (LA; ≤2·5 % of energy (en%)) and arachidonic acid (≤60 mg/d), while maintaining an average US intake of n-3 PUFA or (2) a high-n-3 PUFA, low-n-6 PUFA (H3-L6) intervention designed to lower n-6 LA, while increasing the n-3 PUFA α-linolenic acid (ALA; ≥1·5 en%) and EPA + DHA (≥1000 mg/d). Pre- and intra-intervention nutrient intakes were estimated with six 24 h dietary recalls per subject. Both groups achieved the targeted reductions in dietary LA to ≤2·5 en% (median LA 2·45 (2·1, 3·1); P<0·001). Intakes of n-3 PUFA did not change for the L6 group. Target increases in n-3 ALA (median 1·6 en%, (1·3, 2·0), P<0·001) and EPA + DHA (1482 mg, (374, 2558), P<0·001) were achieved in the H3-L6 group. Dietary changes were validated by corresponding changes in erythrocyte n-6 and n-3 fatty acid composition. Dietary LA can be lowered to ≤2·5 en%, with or without concurrent increases in dietary n-3 PUFA, in an outpatient clinical trial setting using this integrated diet method

Credibility of Low-Strength Static Magnet Therapy as an Attention Control Intervention for a Randomized Controlled Study of CranioSacral Therapy for Migraine Headaches

Developing valid control groups that generate similar perceptions and expectations to experimental complementary and alternative (CAM) treatments can be challenging. The perceived credibility of treatment and outcome expectancy often contributes to positive clinical responses to CAM therapies, thereby confounding efficacy data. As part of a clinical feasibility study, credibility and expectancy data were obtained from subjects suffering from migraine who received either CranioSacral therapy (CST) or an attention-control, sham, and low-strength magnet (LSSM) intervention

Cultural Transformation in Healthcare: How Well Does the Veterans Health Administration Vision for Whole Person Care Fit the Needs of Patients at an Academic Rehabilitation Center?

Background The Veterans Health Administration is undergoing a cultural transformation toward person-driven care referred to as the Whole Health System of Care. Objective This pilot study evaluated whether the Whole Health model resonates with patients of a large public university rehabilitation clinic. Methods Thirty participants completed the Veterans Health Administration's Personal Health Inventory (PHI), and six attended the course "Taking Charge of My Life and Health." Researchers analyzed PHI responses and post-course focus group transcripts. A short post-PHI survey and post-course evaluation were collected. Results Participants agreed the PHI is a simple, useful tool. The course, while well attended, did not meet participants' expectations. Participants wanted access to integrative therapies and opportunities to contribute to healthcare transformation. Conclusion Rehabilitation patients resonated with the Whole Health vision. They expressed enthusiasm for the cultural transformation represented by the model along with frustration that standard healthcare experiences fall short of this vision

Use of dietary linoleic acid for secondary prevention of coronary heart disease and death: evaluation of recovered data from the Sydney Diet Heart Study and updated meta-analysis

Objective To evaluate the effectiveness of replacing dietary saturated fat with omega 6 linoleic acid, for the secondary prevention of coronary heart disease and death.Design Evaluation of recovered data from the Sydney Diet Heart Study, a single blinded, parallel group, randomized controlled trial conducted in 1966-73; and an updated meta-analysis including these previously missing data.Setting Ambulatory, coronary care clinic in Sydney, Australia.Participants 458 men aged 30-59 years with a recent coronary event.Interventions Replacement of dietary saturated fats (from animal fats, common margarines, and shortenings) with omega 6 linoleic acid (from safflower oil and safflower oil polyunsaturated margarine). Controls received no specific dietary instruction or study foods. All non-dietary aspects were designed to be equivalent in both groups.Outcome measures All cause mortality (primary outcome), cardiovascular mortality, and mortality from coronary heart disease (secondary outcomes). We used an intention to treat, survival analysis approach to compare mortality outcomes by group.Results The intervention group (n=221) had higher rates of death than controls (n=237) (all cause 17.6% v 11.8%, hazard ratio 1.62 (95% confidence interval 1.00 to 2.64), P=0.05; cardiovascular disease 17.2% v 11.0%, 1.70 (1.03 to 2.80), P=0.04; coronary heart disease 16.3% v 10.1%, 1.74 (1.04 to 2.92), P=0.04). Inclusion of these recovered data in an updated meta-analysis of linoleic acid intervention trials showed non-significant trends toward increased risks of death from coronary heart disease (hazard ratio 1.33 (0.99 to 1.79); P=0.06) and cardiovascular disease (1.27 (0.98 to 1.65); P=0.07).Conclusions Advice to substitute polyunsaturated fats for saturated fats is a key component of worldwide dietary guidelines for coronary heart disease risk reduction. However, clinical benefits of the most abundant polyunsaturated fatty acid, omega 6 linoleic acid, have not been established. In this cohort, substituting dietary linoleic acid in place of saturated fats increased the rates of death from all causes, coronary heart disease, and cardiovascular disease. An updated meta-analysis of linoleic acid intervention trials showed no evidence of cardiovascular benefit. These findings could have important implications for worldwide dietary advice to substitute omega 6 linoleic acid, or polyunsaturated fats in general, for saturated fats.Trial registration Clinical trials NCT01621087
