RESUMO

We examined relationships between resilience resources (optimism, social support, and neighborhood social cohesion) and cardiovascular disease (CVD) incidence and assessed potential effect-measure modification by psychosocial risk factors (e.g., stress, depression) among adults without CVD in 3 cohort studies (2000-2018): the Jackson Heart Study, the Multi-Ethnic Study of Atherosclerosis, and the Mediators of Atherosclerosis in South Asians Living in America (MASALA) Study. We fitted adjusted Cox models accounting for within-neighborhood clustering while censoring at dropout or non-CVD death. We assessed for effect-measure modification by psychosocial risks. In secondary analyses, we estimated standardized risk ratios using inverse-probability-weighted Aalen-Johansen estimators to account for confounding, dropout, and competing risks (non-CVD deaths) and obtained 95% confidence intervals (CIs) using cluster bootstrapping. For high and medium (versus low) optimism (n = 6,243), adjusted hazard ratios (HRs) for incident CVD were 0.94 (95% CI: 0.78, 1.13) and 0.90 (95% CI: 0.75, 1.07), respectively. Corresponding HRs were 0.88 (95% CI: 0.74, 1.04) and 0.92 (95% CI: 0.79, 1.06) for social support (n = 7,729) and 1.10 (95% CI: 0.94, 1.29) and 0.99 (95% CI: 0.85, 1.16) for social cohesion (n = 7,557), respectively. Some psychosocial risks modified CVD HRs. Secondary analyses yielded similar findings. For optimism and social support, an inverse relationship was frequently most compatible with the data, but a positive relationship was also compatible. For neighborhood social cohesion, positive and null relationships were most compatible. Thus, specific resilience resources may be potential intervention targets, especially among certain subgroups.

RESUMO

BACKGROUND: Mindfulness-based programs have the potential to improve the well-being of undergraduate students by reducing anxiety, depression, and isolation in the wake of the COVID-19 pandemic. The aim of this qualitative study was to explore lived experiences of undergraduates in a mindfulness-based program at a "college of opportunity" that has high proportions of first-generation college students. Specifically, we sought to: (1) explore the application of mindfulness practices in students' daily lives; (2) explore how participants believe mindfulness training affected their health and well-being; (3) learn participants' recommendations and suggested changes for mindfulness-based interventions in future iterations. METHODS: Students were recruited from XXX and consented to participate in semi-structured digitally conducting interviews after the completion of the 8-week intervention in the Fall/Spring 2020 academic year. Data were analyzed using Applied Thematic Analysis and a codebook was constructed using a consensus-driven process using both a priori and emergent coding. All transcripts were double-coded, and concordance was achieved for all interviews. RESULTS: Qualitative results indicated that the most applied practices were those that could be easily incorporated into a daily routine. Furthermore, students reported an increased ability to cope with a variety of stressors, decreased reactivity, and enhanced resilience specifically concerning mental health challenges. Additionally, engaging in mindfulness training improved students' ability to navigate social distancing measures, other COVID-19-specific stress, and enhanced motivation for self-care practices to sustain well-being. Concerning preferred intervention delivery modality, participants stated that due to multiple, growing responsibilities (e.g., pressures of commuting to class) they preferred in-person delivery, shorter sessions over a longer period, with classes in the morning or early afternoon. CONCLUSIONS: Findings provide pragmatic and psychosocial insights into students' application of mindfulness training across personal, professional, and academic domains enhancing their well-being. This work builds on qualitative work concerning students' perceptions and applications of mindfulness while offering insights into the future of mindfulness programs among undergraduates. TRIAL REGISTRATION: Clinicaltrials.gov NCT03124446.

RESUMO

BACKGROUND: Psychosocial stressors increase the risks for cardiovascular disease across diverse populations. However, neighborhood level resilience resources may protect against poor cardiovascular health (CVH). This study used data from three CVH cohorts to examine longitudinally the associations of a resilience resource, perceived neighborhood social cohesion (hereafter referred to as neighborhood social cohesion), with the American Heart Association's Life's Simple 7 (LS7), and whether psychosocial stressors modify observed relationships. METHODS: We examined neighborhood social cohesion (measured in tertiles) and LS7 in the Jackson Heart Study, Multi-Ethnic Study of Atherosclerosis, and Mediators of Atherosclerosis in South Asians Living in America study. We used repeated-measures, modified Poisson regression models to estimate the relationship between neighborhood social cohesion and LS7 (primary analysis, n = 6,086) and four biological metrics (body mass index, blood pressure, cholesterol, blood glucose; secondary analysis, n = 7,291). We assessed effect measure modification by each psychosocial stressor (e.g., low educational attainment, discrimination). RESULTS: In primary analyses, adjusted prevalence ratios (aPR) and 95% confidence intervals (CIs) for ideal/intermediate versus poor CVH among high or medium (versus low) neighborhood social cohesion were 1.01 (0.97-1.05) and 1.02 (0.98-1.06), respectively. The psychosocial stressors, low education and discrimination, functioned as effect modifiers. Secondary analyses showed similar findings. Also, in the secondary analyses, there was evidence for effect modification by income. CONCLUSION: We did not find much support for an association between neighborhood social cohesion and LS7, but did find evidence of effect modification. Some of the effect modification results operated in unexpected directions. Future studies should examine neighborhood social cohesion more comprehensively and assess for effect modification by psychosocial stressors.

RESUMO

Objective In the United States, people of color (POC) are disproportionately affected by various sources of stress and prevalent mental and physical health issues that may benefit from Mindfulness-based Interventions (MBIs). However, effects of MBIs for POC are unclear. This meta-analysis examines the efficacy of MBIs through randomized controlled trials (RCTs) that included predominately POC (≥75% of the sample). Method: Random effects models were used to synthesize effect sizes. A total of 24 RCT samples were analyzed. Results: Samples were on average 94.4% POC and predominantly from low-income backgrounds (total N = 2,156). At post-treatment, MBIs yielded small but statistically superior outcomes to active controls (Hedges' g = 0.11) and inactive controls (g = 0.26). Compared to active controls, MBIs' effects on well-being were smaller than their effects on other outcome types. Compared to inactive controls, MBIs that focused on non-clinical populations and had higher proportion of POC had larger effect sizes. Attrition rates of MBIs did not differ from other active conditions in outpatient settings. Conclusion: Findings provide modest, preliminary empirical support for MBIs among POC. We discuss main findings, limitations, and implications for future MBI research for health promotion among POC.

RESUMO

ABSTRACT: We are at a difficult time in history with societal increases in stress, loneliness, and psychopathology, along with high rates of obesity, sedentary lifestyles, and chronic pain. Mindfulness interventions offer promise to address these societal issues. However, in order to make best use of the opportunities revealed by our current challenges, we must: (1) tackle these issues head-on with inclusive, innovative, and creative experimental designs and interventions, and (2) collectively adhere to rigorous, high quality methods so as to provide an evidence-based integration of mindfulness interventions into mainstream medicine and public health.We find there are several areas for which important advances are happening, including sampling socially diverse populations, examining mechanisms of action, pain management, and health behaviors. Furthermore, rigorous methods, including measurement, causal inference from control groups, delivery and scalability of mindfulness interventions, and effect modifiers to determine who mindfulness programs work best for are also gaining traction. This special issue on Mindfulness: Biobehavioral Mechanisms and Health Outcomes attends to many of these issues, several of which are highlighted in this editorial perspective.

RESUMO

OBJECTIVE: To evaluate effects of a mindfulness-based program, adapted to the young adult life course stage (age, 18-29 years), named Mindfulness-Based College (MB-College). The primary outcome was a young adult health summary score, composed of key health risk factors: body mass index, physical activity, fruit and vegetable intake, alcohol consumption, stress, loneliness, and sleep duration. Secondary outcomes were hypothesized self-regulation mechanisms, including attention control, interoceptive awareness, and emotion regulation. METHODS: This was a stage 1 randomized controlled trial of the 9-week MB-College program (n = 47) versus enhanced usual care control (n = 49) including students from three universities. Assessments were at baseline, during the beginning of the college term when stress is typically lower, and at MB-College completion (3-month follow-up), when term-related stress is typically higher. Intention-to-treat, linear regression analyses estimated the marginal effects of MB-College versus control on the outcomes. RESULTS: MB-College participants (mean age = 20 years, 68% female, 37% racial minorities) demonstrated improved health summary scores at follow-up compared with control participants whose health summary scores worsened (marginal effect for MB-College versus control = 0.23; p = .004). Effects on loneliness were pronounced (marginal effect = -3.11 for the Revised University of Los Angeles Loneliness Scale score; p = .03). Secondary analyses showed significant impacts of MB-College on hypothesized self-regulation mechanisms (e.g., Sustained Attention to Response Task correct no-go percent, p = .0008; Multidimensional Assessment of Interoceptive Awareness, p < .0001; Center for Epidemiologic Studies-Depression scale, p = .03). CONCLUSIONS: Findings of this early stage clinical trial suggest that MB-College may foster well-being in young adults.Trial Registration: NCT03124446.

RESUMO

Obesity is understood to be an inflammatory condition characterized in part by changes in resident immune cell populations in adipose tissue. However, much of this knowledge has been obtained through experimental animal models. Epigenetic mechanisms, such as DNA methylation may be useful tools for characterizing the changes in immune cell populations in human subjects. In this study, we introduce a simple and intuitive method for assessing cellular infiltration by blood into other heterogeneous, admixed tissues such as adipose tissue, and apply this approach in a large human cohort study. Associations between higher leukocyte infiltration, measured by evaluating a distance measure between the methylation signatures of leukocytes and adipose tissue, and increasing body mass index (BMI) or android fat mass (AFM) were identified and validated in independent replication samples for CD4 (pBMI = 0.009, pAFM = 0.020), monocytes (pBMI = 0.001, pAFM = 4.3 × 10-4 ), and dendritic cells (pBMI = 0.571, pAFM = 0.012). Patterns of depletion with increasing adiposity were observed for plasma B (pBMI = 0.430, pAFM = 0.004) and immature B (pBMI = 0.022, pAFM = 0.042) cells. CD4, dendritic, monocytes, immature B, and plasma B cells may be important agents in the inflammatory process. Finally, the method used to assess leukocyte infiltration in this study is straightforwardly extended to other cell types and tissues in which infiltration might be of interest.

RESUMO

Green space has been associated with better health and well-being. However, most studies have been cross-sectional with limited long-term exposure data. Further, research is limited in what type of green space is beneficial for health. We conducted a longitudinal study to assess sensitive periods (birth, childhood or adulthood) of exposure to different types of green space in association with adult blood pressure and body mass index (BMI). Using longitudinal data from the New England Family Study (1960-2000) and multilevel regression analysis, we examined associations between time-varying markers of residential exposure to green space, and adult BMI, systolic (SBP) and diastolic blood pressure (DBP) (N = 517). We created three exposure metrics: distance, average area, and green space count in the neighborhood throughout the life-course. In adjusted models, living one mile farther away from a green space at birth was associated with a 5.6 mmHg higher adult SBP (95%CI: 0.7, 10.5), and 3.5 mmHg higher DBP (95%CI: 0.3, 6.8). One more green space in the neighborhood at birth was also associated with lower DBP (-0.2 mmHg, 95%CI: -0.4, -0.02) in adulthood. Finally, average area of green space was not associated with SBP, DBP nor BMI. Analysis by type of green space suggested that parks may be more relevant than playgrounds, cemeteries or golf courses. Our study suggests that the perinatal period may be a critical time-period where living closer to green spaces may lower hypertension risk in adulthood, but not obesity.

RESUMO

BACKGROUND: Studies have shown adverse effects of a disadvantaged childhood on adult health-promoting behaviors and related outcomes. Optimism and social support have been linked to greater likelihood of engaging in healthy behavior, but it is unclear whether these positive psychosocial factors may buffer harmful effects of early adversity. This study aims to determine if optimism and social support in adulthood can modify effects of childhood disadvantage on health behavior-related outcomes. METHODS: Longitudinal data were analyzed from a subset of participants in a US birth cohort established in 1959-1966 (ns of 681-840, per outcome). An index of childhood social disadvantage was derived from adverse socioeconomic and family stability factors reported by mothers at child's birth and age 7 years. Health behavior-related outcomes were self-reported when participants were of mean age 47 years. Multivariable adjusted robust Poisson regressions were performed. RESULTS: Regardless of level of childhood social disadvantage, we found higher levels of optimism and social support were both associated with higher probabilities of being a non-smoker (relative risk [RR]optimism = 1.17, 95% confidence interval [CI] = 1.09-1.26; RRsocial support = 1.24, 95%CI = 1.11-1.39), having a healthy diet (RRoptimism = 1.25, 95%CI = 1.10-1.43; RRsocial support = 1.27, 95%CI = 1.04-1.56), and a healthy body mass index (RRoptimism = 1.18, 95%CI = 1.00-1.40; RRsocial support = 1.29, 95%CI = 1.00-1.66). Interactions link higher optimism or social support with lower risk of smoking among those with moderate childhood disadvantage. CONCLUSIONS: Overall, these findings are consistent with the possibility that positive psychosocial resources contribute to maintaining a healthy lifestyle in mid-adulthood and may buffer effects of childhood social disadvantage.

RESUMO

BACKGROUND: Self-management of health is important for improving health outcomes among primary care patients with chronic disease. Anxiety and depressive disorders are common and interfere with self-regulation, which is required for disease self-management. An insurance-reimbursable mindfulness intervention integrated within primary care may be effective for enhancing chronic disease self-management behaviors among primary care patients with anxiety, depression, trauma, and stress-related and adjustment disorders compared with the increasingly standard practice of referring patients to outside mindfulness resources. OBJECTIVE: Mindfulness Training for Primary Care (MTPC) is an 8-week, referral-based, insurance-reimbursable program integrated into safety-net health system patient-centered medical homes. We hypothesized that MTPC would be more effective for catalyzing chronic disease self-management action plan initiation within 2 weeks, versus a low-dose comparator (LDC) consisting of a 60-min mindfulness introduction, referral to community and digital resources, and addition to a 6-month waitlist for MTPC. PARTICIPANTS: Primary care providers (PCPs) and mental health clinicians referred 465 patients over 12 months. All participants had a DSM-V diagnosis. DESIGN AND INTERVENTIONS: Participants (N = 136) were randomized in a 2:1 allocation to MTPC (n = 92) or LDC (n = 44) in a randomized controlled comparative effectiveness trial. MTPC incorporates mindfulness, self-compassion, and mindfulness-oriented behavior change skills and is delivered as insurance-reimbursable visits within primary care. Participants took part in a chronic disease self-management action planning protocol at week 7. MAIN MEASURES: Level of self-reported action plan initiation on the action plan initiation survey by week 9. KEY RESULTS: Participants randomized to MTPC, relative to LDC, had significantly higher adjusted odds of self-management action plan initiation in an intention-to-treat analysis (OR = 2.28; 95% CI = 1.02 to 5.06, p = 0.025). CONCLUSIONS: An 8-week dose of mindfulness training is more effective than a low-dose mindfulness comparator in facilitating chronic disease self-management behavior change among primary care patients.

RESUMO

BACKGROUND: Reproductive factors provide an early window into a woman's coronary heart disease (CHD) risk; however, their contribution to CHD risk stratification is uncertain. METHODS AND RESULTS: In the Women's Health Initiative Observational Study, we constructed Cox proportional hazards models for CHD including age, pregnancy status, number of live births, age at menarche, menstrual irregularity, age at first birth, stillbirths, miscarriages, infertility ≥1 year, infertility cause, and breastfeeding. We next added each candidate reproductive factor to an established CHD risk factor model. A final model was then constructed with significant reproductive factors added to established CHD risk factors. Improvement in C statistic, net reclassification index (or net reclassification index with risk categories of <5%, 5 to <10%, and ≥10% 10-year risk of CHD), and integrated discriminatory index were assessed. Among 72 982 women (CHD events, n=4607; median follow-up,12.0 [interquartile range, 8.3-13.7] years; mean [standard deviation] age, 63.2 [7.2] years), an age-adjusted reproductive risk factor model had a C statistic of 0.675 for CHD. In a model adjusted for established CHD risk factors, younger age at first birth, number of still births, number of miscarriages, and lack of breastfeeding were positively associated with CHD. Reproductive factors modestly improved model discrimination (C statistic increased from 0.726 to 0.730; integrated discriminatory index, 0.0013; P<0.0001). Net reclassification for women with events was not improved (net reclassification index events, 0.007; P=0.18); and, for women without events, net reclassification was marginally improved (net reclassification index nonevents, 0.002; P=0.04) CONCLUSIONS: Key reproductive factors are associated with CHD independently of established CHD risk factors, very modestly improve model discrimination, and do not materially improve net reclassification.

RESUMO

OBJECTIVE: Childhood socioeconomic disadvantage is associated with adulthood obesity risk; however, epigenetic mechanisms are poorly understood. This work's objective was to evaluate whether associations of childhood socioeconomic disadvantage with adulthood body mass index (BMI) are mediated by DNA methylation. METHODS: Participants were 141 men and women from the New England Family Study, prospectively followed prenatally through a mean age of 47 years. Epigenomewide DNA methylation was evaluated in peripheral blood and adipose tissue obtained at adulthood, using the Infinium HumanMethylation450K BeadChip. Childhood socioeconomic status (SES) at age 7 years was assessed directly from parents' reports. Offspring adiposity was directly assessed using BMI at a mean age of 47 years. Associations of SES, DNA methylation, and BMI were estimated using least square estimators. Statistical mediation analyses were performed using joint significance test and bootstrapping. RESULTS: Of CpG sites significant at the 25% false discovery rate level in epigenomewide methylation BMI analyses, 91 sites in men and 71 sites in women were additionally significant for SES-methylation associations (p < .001) in adipose tissue. Many involved genes biologically relevant for development of obesity, including fatty acid synthase, transmembrane protein 88, signal transducer and activator of transcription 3, and neuritin 1. There was no evidence of epigenetic mediation in peripheral blood leukocytes. CONCLUSIONS: DNA methylation at specific genes may be mediators of associations between childhood socioeconomic disadvantage and mid-life BMI in adipose tissue. Findings motivate continued efforts to study if and how childhood socioeconomic disadvantage is biologically embedded at the level of the epigenome in regions etiologically relevant for adiposity.

RESUMO

OBJECTIVE: Despite variability in the burden of elevated depressive symptoms by sex and race and differences in the incidence of metabolic syndrome, few prior studies describe the longitudinal association of depressive symptoms with metabolic syndrome in a diverse cohort. We tested whether baseline and time-varying depressive symptoms were associated with metabolic syndrome incidence in black and white men and women from the Coronary Artery Risk Development in Young Adults study. METHODS: Participants reported depressive symptoms using the Center for Epidemiologic Studies Depression Scale at four examinations between 1995 and 2010. At those same examinations, metabolic syndrome was determined. Cox proportional hazards models were used to examine the associations of depressive symptoms on the development of metabolic syndrome in 3208 participants without metabolic syndrome at baseline. RESULTS: For 15 years, the incidence rate of metabolic syndrome (per 10,000 person-years) varied by race and sex, with the highest rate in black women (279.2), followed by white men (241.9), black men (204.4), and white women (125.3). Depressive symptoms (per standard deviation higher) were associated with incident metabolic syndrome in white men (hazard ratio = 1.25, 95% confidence interval = 1.08-1.45) and white women (hazard ratio = 1.17, 95% confidence interval = 1.00-1.37) after adjustment for demographic characteristics and health behaviors. There was no significant association between depression and metabolic syndrome among black men or black women. CONCLUSIONS: Higher depressive symptoms contribute modestly to the onset of metabolic syndrome among white adults.

RESUMO

PURPOSE: To evaluate whether dispositional mindfulness (defined as the ability to attend nonjudgmentally to one's own physical and mental processes) is associated with obesity and central adiposity. METHODS: Study participants (n = 394) were from the New England Family Study, a prospective birth cohort, with median age 47 years. Dispositional mindfulness was assessed using the Mindful Attention Awareness Scale (MAAS). Central adiposity was assessed using dual-energy X-ray absorptiometry (DXA) scans with primary outcomes android fat mass and android/gynoid ratio. Obesity was defined as body mass index ≥30 kg/m(2). RESULTS: Multivariable-adjusted regression analyses demonstrated that participants with low vs. high MAAS scores were more likely to be obese (prevalence ratio for obesity = 1.34 (95 % confidence limit (CL): 1.02, 1.77)), adjusted for age, gender, race/ethnicity, birth weight, childhood socioeconomic status, and childhood intelligence. Furthermore, participants with low vs. high MAAS level had a 448 (95 % CL 39, 857) g higher android fat mass and a 0.056 (95 % CL 0.003, 0.110) greater android/gynoid fat mass ratio. Prospective analyses demonstrated that participants who were not obese in childhood and became obese in adulthood (n = 154) had -0.21 (95 % CL -0.41, -0.01; p = 0.04) lower MAAS scores than participants who were not obese in childhood or adulthood (n = 203). CONCLUSIONS: Dispositional mindfulness may be inversely associated with obesity and adiposity. Replication studies are needed to adequately establish whether low dispositional mindfulness is a risk factor for obesity and adiposity.

RESUMO

BACKGROUND: Individual health behaviours are considered important risk factors for cardiometabolic diseases. These behaviours may be socially patterned by early exposure to social disadvantage, but few studies have prospectively tested this hypothesis empirically. AIM: This study investigated whether childhood social disadvantage was associated with likelihood of engaging in less healthy behaviours 40 years later. SUBJECTS AND METHODS: Prospective data were analysed from the New England Family Study, a 2005-2007 adult follow-up of a cohort initiated in 1959-1966 (n = 565). Childhood social environment (age 7 years) was assessed using a cumulative index of socioeconomic and family stability factors. Logistic regression models evaluated associations between social disadvantage and each health-related behaviour and obesity in adulthood. RESULTS: Relative to low disadvantage, higher disadvantage was associated with 3.6-fold greater odds of smoking (95% CI = 1.9-7.0), 4.8-fold greater odds (in women only) of excess alcohol consumption (95% CI = 1.6-14.2) and 2.7-fold greater odds of obesity (95% CI = 1.3-5.5), but was not associated with unhealthy diet or physical inactivity. CONCLUSION: These findings suggest childhood social disadvantage may contribute to adult cardiometabolic disease by predisposing children to adopt certain unhealthy behaviours. If replicated, such findings may support intervention strategies that target social environmental factors and behavioural pathways that are established early in life.

RESUMO

OBJECTIVE: Increasing evidence suggests that early life factors may influence coronary heart disease (CHD) risk; however, little is known about the contributions of prenatal cortisol. Objectives were to prospectively assess the associations of maternal cortisol levels during pregnancy with offspring's 10-year CHD risk during middle age. METHODS: Participants were 262 mother-offspring dyads from the New England Family Study. Maternal free cortisol was assessed in third-trimester maternal serum samples. Ten-year CHD risk was calculated in offspring at a mean age of 42 years, using the validated Framingham risk algorithm incorporating diabetes, systolic and diastolic blood pressure, total and high-density lipoprotein cholesterol, smoking, age, and sex. RESULTS: In multivariable-adjusted linear regression analyses adjusted for age and race/ethnicity, high versus low maternal cortisol tertile was associated with 36.7% (95% confidence interval [CI] = 8.4% to 72.5%) greater mean 10-year CHD risk score in women. There was no association in men (-2.8%, 95% CI = -23.8% to 24.0%). Further adjustment for in utero socioeconomic position showed 26.1% (95% CI = -0.5% to 59.9%) greater CHD risk in women. Adjustment for maternal age and size for gestational age had little effect on findings. CONCLUSIONS: Maternal prenatal cortisol levels were positively associated with 10-year CHD risk among female, and not male, offspring. Adjusting for socioeconomic position during pregnancy reduced effect size in women, suggesting that it may be a common prior factor in both maternal cortisol and CHD risk. These findings provide evidence that targeting mothers who have elevated prenatal cortisol levels, including elevated cortisol in the setting of low socioeconomic position, may potentially reduce long-term CHD risk in their offspring.

RESUMO

BACKGROUND: Mindfulness (the ability to attend nonjudgmentally to one's own physical and mental processes) is receiving substantial interest as a potential determinant of health. However, little is known whether mindfulness is associated with cardiovascular health. PURPOSE: The aim of this study is to evaluate whether dispositional mindfulness is associated with cardiovascular health. METHOD: Study participants (n = 382) were from the New England Family Study, born in Providence, RI, USA, with mean age 47 years. Dispositional mindfulness was assessed using the Mindful Attention Awareness Scale (MAAS). Cardiovascular health was assessed based on American Heart Association criteria. Cross-sectional multivariable-adjusted log binomial regression analyses were performed. RESULTS: Analyses demonstrated that those with high vs. low MAAS had prevalence ratio (PR) for good cardiovascular health of 1.83 (95 % confidence interval (CI) 1.07, 3.13), adjusted for age, gender, and race/ethnicity. There were significant associations of high vs. low mindfulness with nonsmoking (PR = 1.37, 95 % CI 1.06, 1.76), body mass index <25 kg/m(2) (PR = 2.17, 95 % CI 1.16, 4.07), fasting glucose <100 mg/dL (PR = 1.47, 95 % CI 1.06, 2.04), and high physical activity (PR = 1.56, 95 % CI 1.04, 2.35), but not blood pressure, total cholesterol, or fruit/vegetable consumption. Exploratory mediation analyses suggested that sense of control and depressive symptomatology may be mediators. CONCLUSION: This study demonstrated preliminary cross-sectional evidence that dispositional mindfulness is positively associated with cardiovascular health, with the associations particularly driven by smoking, body mass index, fasting glucose, and physical activity. If in future research mindfulness-based practices are found to consistently improve cardiovascular disease risk factors, such interventions may have potential to strengthen effects of cardiovascular health promotion programs.

RESUMO

Childhood adversity, characterized by abuse, neglect, and household dysfunction, is a problem that exerts a significant impact on individuals, families, and society. Growing evidence suggests that adverse childhood experiences (ACEs) are associated with health decline in adulthood, including cardiovascular disease (CVD). In the current review, we first provide an overview of the association between ACEs and CVD risk, with updates on the latest epidemiological evidence. Second, we briefly review plausible pathways by which ACEs could influence CVD risk, including traditional risk factors and novel mechanisms. Finally, we highlight the potential implications of ACEs in clinical and public health. Information gleaned from this review should help physicians and researchers in better understanding potential long-term consequences of ACEs and considering adapting current strategies in treatment or intervention for patients with ACEs.

RESUMO

The purpose of this review is to provide (1) a synopsis on relations of mindfulness with cardiovascular disease (CVD) and major CVD risk factors, and (2) an initial consensus-based overview of mechanisms and theoretical framework by which mindfulness might influence CVD. Initial evidence, often of limited methodological quality, suggests possible impacts of mindfulness on CVD risk factors including physical activity, smoking, diet, obesity, blood pressure, and diabetes regulation. Plausible mechanisms include (1) improved attention control (e.g., ability to hold attention on experiences related to CVD risk, such as smoking, diet, physical activity, and medication adherence), (2) emotion regulation (e.g., improved stress response, self-efficacy, and skills to manage craving for cigarettes, palatable foods, and sedentary activities), and (3) self-awareness (e.g., self-referential processing and awareness of physical sensations due to CVD risk factors). Understanding mechanisms and theoretical framework should improve etiologic knowledge, providing customized mindfulness intervention targets that could enable greater mindfulness intervention efficacy.

RESUMO

The objective of this study was to examine the cross-sectional association between coping styles and allostatic load among African American adults in the Jackson Heart Study (2000-2004). Coping styles were assessed using the Coping Strategies Inventory-Short Form; allostatic load was measured by using 9 biomarkers standardized into z-scores. Sex-stratified multivariable linear regressions indicated that females who used disengagement coping styles had significantly higher allostatic load scores (ß = 0.016; 95% CI, 0.001-0.032); no such associations were found in males. Future longitudinal investigations should examine why disengagement coping style is linked to increased allostatic load to better inform effective interventions and reduce health disparities among African American women.
