Background Psychological well-being is important among individuals with myocardial infarction (MI) given the clear links between stress, depression, and adverse cardiovascular outcomes. Stress and depressive disorders are more prevalent in women than men after MI. Resilience may protect against stress and depressive disorders after a traumatic event. Longitudinal data are lacking in populations post MI. We examined the role of resilience in the psychological recovery of women post MI, over time. Methods and Results We analyzed a sample from a longitudinal observational multicenter study (United States, Canada) of women post MI, between 2016 and 2020. Perceived stress (Perceived Stress Scale-4 [PSS-4]) and depressive symptoms (Patient Health Questionnaire-2 [PHQ-2]) were assessed at baseline (time of MI) and 2 months post MI. Demographics, clinical characteristics, and resilience (Brief Resilience Scale [BRS]) were collected at baseline. Low and normal/high resilience groups were established as per published cutoffs (BRS scores <3 or ≥3). Mixed-effects modeling was used to examine associations between resilience and psychological recovery over 2 months. The sample included 449 women, mean (SD) age, 62.2 (13.2) years, of whom 61.1% identified as non-Hispanic White, 18.5% as non-Hispanic Black, and 15.4% as Hispanic/Latina. Twenty-three percent had low resilience. The low resilience group had significantly higher PSS-4 and PHQ-2 scores than the normal/high resilience group at all time points. In adjusted models, both groups showed a decrease in PSS-4 scores over time. Conclusions In a diverse cohort of women post MI, higher resilience is associated with better psychological recovery over time. Future work should focus on developing strategies to strengthen resilience and improve psychological well-being for women with MI.

Introduction/UNASSIGNED:Experiencing psychosocial stress is associated with poor health outcomes such as hypertension and obesity, which are risk factors for developing cardiovascular disease. African American women experience disproportionate risk for cardiovascular disease including exposure to high levels of psychosocial stress. We hypothesized that psychosocial stress, such as perceived stress overload, may influence epigenetic marks, specifically DNA methylation (DNAm), that contribute to increased risk for cardiovascular disease in African American women. Methods/UNASSIGNED:We conducted an epigenome-wide study evaluating the relationship of psychosocial stress and DNAm among African American mothers from the Intergenerational Impact of Genetic and Psychological Factors on Blood Pressure (InterGEN) cohort. Linear mixed effects models were used to explore the epigenome-wide associations with the Stress Overload Scale (SOS), which examines self-reported past-week stress, event load and personal vulnerability. Results/UNASSIGNED:. Conclusions/UNASSIGNED:This study provides foundational knowledge for future studies examining epigenetic associations with stress and other psychosocial measures in African Americans, a key area for growth in epigenetics. Future studies including larger sample sizes and replication data are warranted.

Introduction/UNASSIGNED:There are significant and pervasive disparities in police violence and discrimination toward African Americans/Blacks. It is possible that these disparities may lead to heightened vulnerability for poor mental health outcomes. The purpose of this study was to ascertain the associations between experiences of police discrimination and depressive symptoms in a community-based sample of African American/Black women. Methods/UNASSIGNED:We performed a cross-sectional multivariable regression analysis using data from the Intergenerational Impact of Genetic and Psychological Factors on Blood Pressure Study that were collected over a 4-year period from September 2015 to June 2019. Depressive symptoms were assessed using 21 items from the Beck Depression Inventory. Police discrimination was assessed by questionnaires ascertaining experiences of discrimination by police; harassment by police or security guards; and experiences of being unfairly stopped, searched, threatened, or abused by police. Results/UNASSIGNED:<0.01). Conclusion/UNASSIGNED:African American/Black women who experienced police discrimination experienced higher prevalence of depressive symptoms. There is an urgent need for reliable population-level data on police mistreatment and interventions at the individual, community, and societal levels.

BACKGROUND:The American Heart Association created the Life's Simple 7 (LS7) metrics to promote cardiovascular health by achieving optimal levels of blood pressure, cholesterol, blood sugar, physical activity, diet, weight, and smoking status. The degree to which psychosocial factors such as stress and depression impact one's ability to achieve optimal cardiovascular health is unclear, particularly among hypertensive African Americans. METHODS:Cross-sectional analyses included 1,819 African Americans with hypertension participating in the Jackson Heart Study (2000-2004). Outcomes were LS7 composite and individual component scores (defined as poor, intermediate, ideal). High perceived chronic stress was defined as the top quartile of Weekly Stress Inventory scores. High depressive symptoms were defined as Center for Epidemiologic Studies Depression scale scores of ≥16. We compared four groups: high stress alone; high depressive symptoms alone; high stress and high depressive symptoms; low stress and low depressive symptoms (reference) using linear regression for total LS7 scores and logistic regression for LS7 components. RESULTS:Participants with both high stress and depressive symptoms had lower composite LS7 scores (B [95% confidence interval-CI]= -0.34 [-0.65 to -0.02]) than those with low stress and depressive symptoms in unadjusted and age/sex-adjusted models. They also had poorer health status for smoking (OR [95% CI]= 0.52 [0.35-0.78]) and physical activity [OR (95% CI)= 0.71 (0.52-0.95)] after full covariate adjustment. CONCLUSIONS:The combination of high stress and high depressive symptoms was associated with poorer LS7 metrics in hypertensive African Americans. Psychosocial interventions may increase the likelihood of engaging in behaviors that promote optimal cardiovascular health.

High blood pressure (BP) based on measurements obtained in the office setting has been associated with the presence and level of coronary artery calcification (CAC)-a measure of subclinical atherosclerosis. We studied the association between out-of-office BP and CAC among 557 participants who underwent 24-hour ambulatory BP monitoring at visit 1 in 2000-2004 and a computed tomography scan at visit 2 in 2005-2008 as part of the JHS (Jackson Heart Study)-a community-based cohort of African American adults. Mean awake, asleep, and 24-hour BP were calculated for each participant. Among participants included in this analysis, 279 (50%) had any CAC defined by an Agatston score >0. After multivariable adjustment including office systolic BP (SBP), the prevalence ratios for any CAC comparing the highest versus the lowest quartiles of SBP on ambulatory BP monitoring were 1.08 (95% CI, 0.84-1.39) for awake SBP, 1.32 (95% CI, 1.01-1.74) for asleep SBP, and 1.19 (95% CI, 0.91-1.55) for 24-hour SBP. After multivariable adjustment including office diastolic BP, the prevalence ratios for any CAC comparing the highest versus the lowest quartiles of awake, asleep, and 24-hour diastolic BP were 1.27 (95% CI, 1.02-1.59), 1.29 (95% CI, 1.02-1.64), and 1.25 (95% CI, 0.99-1.59), respectively. The current results suggest that higher asleep SBP and higher awake and asleep diastolic BP may be risk factors for subclinical atherosclerosis and underscore the potential role of ambulatory BP monitoring in identifying individuals at high risk for coronary artery disease.

Although mean blood pressure (BP) increases with age, there may be a subset of individuals whose BP does not increase with age. Characterizing the population that maintains normal BP could inform hypertension prevention efforts. We determined the proportion of Jackson Heart Study participants that maintained normal BP at 3 visits over a median of 8 years. Normal BP was defined as systolic BP <120 mm Hg and diastolic BP <80 mm Hg without antihypertensive medication. We identified lifestyle and psychosocial factors associated with maintaining normal BP and calculated the incidence rate for cardiovascular disease (CVD). Overall, 757 of 3432 participants (22.1%) had normal BP at baseline, and 262 of these participants (34.6%) maintained normal BP. Among participants with normal BP at baseline, normal body mass index (risk ratio [RR] 1.37 [95% CI, 1.08-1.75]), ideal physical activity (RR, 1.28 [95% CI, 0.99-1.65]), and never smoking (RR, 1.48 [95% CI, 0.99-2.20]) at baseline were associated with maintaining normal BP. Maintaining normal body mass index (RR, 1.42 [95% CI, 1.10-1.84]) and ideal physical activity (RR, 1.51 [95% CI, 1.18-1.94]) at all study visits were associated with maintaining normal BP. The cardiovascular disease incidence rate was 4.5, 6.3, and 16.4 per 1000 person-years among participants who maintained normal BP, had normal BP at baseline but did not maintain normal BP, and had elevated BP or hypertension at baseline, respectively, over 5.9 years of follow-up. These data suggest that maintaining normal body mass index and ideal physical activity are potential approaches for African American adults to maintain normal BP.

Hypertension is a risk factor for cardiovascular disease. Black women have high rates of hypertension compared to women of other racial or ethnic groups and are disproportionately affected by psychosocial stressors such as racial discrimination, gender discrimination, and caregiving stress. Evidence suggests that stress is associated with incident hypertension and hypertension risk. Stress management is associated with improvements improved blood pressure outcomes. The purpose of this review is to synthesize evidence on effects of stress management interventions on blood pressure in Black women. A comprehensive search of scientific databases was conducted. Inclusion criteria included studies that were: (1) primary research that tested an intervention; (2) in the English language; (3) included African-American women; (4) incorporated stress in the intervention; (5) included blood pressure as an outcome; and (6) were US based. Eighteen studies met inclusion criteria. Ten (56%) studies tested meditation-based interventions, two (11%) tested coping and affirmation interventions, and six (33%) tested lifestyle modification interventions that included stress management content. Thirteen of the studies were randomized controlled trials. Reductions in blood pressure were observed in all of the meditation-based interventions, although the magnitude and statistical significance varied. Comprehensive lifestyle interventions were also efficacious for reducing blood pressure, although the relative contribution of stress management versus behavior modification could not be evaluated. Coping and affirmation interventions did not affect blood pressure. Most of the reviewed studies included small numbers of Black women and did not stratify results by race and gender, so effects remain unclear. This review highlights the urgent need for studies specifically focusing on Black women. Given the extensive disparities in cardiovascular disease morbidity and mortality, whether stress management can lower blood pressure and improve primary and secondary cardiovascular disease prevention among Black women is an important question for future research.

PURPOSE OF REVIEW/OBJECTIVE:Medication adherence is critical for effective management of hypertension, yet half of patients with hypertension are non-adherent to medications. In this review, we describe and critically evaluate medication adherence interventions published in the past 3 years for patients with hypertension. RECENT FINDINGS/RESULTS:We identified 1593 articles and 163 underwent full review, of which 42 studies met the inclusion criteria. Studies were classified into eight categories: simplification of medication regimen (e.g., fixed dose combination pills); electronic Health (eHealth) tools (e.g., text messaging reminders); behavioral counseling (e.g., motivational interviewing); healthcare system changes (e.g., patient-centered medical home); patient education; multicomponent chronic disease management program; home blood pressure monitoring; and financial incentives. Studies utilizing strategies to simplify medication regimens, eHealth tools, patient education, and behavioral counseling were most likely to report positive findings. Interventions targeting patient behavior were more likely to be associated with improvements in medication adherence compared to those targeting providers or the healthcare system. eHealth tools show promise for augmenting behavioral interventions. A major limitation of included trials was short study duration and use of self-report measures of medication adherence. Future research should explore how complex interventions that utilize a combination of evidence-based strategies and target multiple adherence behaviors (e.g., both day-to-day medication taking and long-term persistence) may be efficacious in improving medication adherence.

BACKGROUND:Tablet and smartphone ownership have increased among US adults over the past decade. However, the degree to which people use mobile devices to help them make medical decisions remains unclear. OBJECTIVE:The objective of this study is to explore factors associated with self-reported use of tablets or smartphones to support medical decision making in a nationally representative sample of US adults. METHODS:Cross-sectional data from participants in the 2018 Health Information National Trends Survey (HINTS 5, Cycle 2) were evaluated. There were 3504 responses in the full HINTS 5 Cycle 2 data set; 2321 remained after eliminating respondents who did not have complete data for all the variables of interest. The primary outcome was use of a tablet or smartphone to help make a decision about how to treat an illness or condition. Sociodemographic factors including gender, race/ethnicity, and education were evaluated. Additionally, mobile health (mHealth)- and electronic health (eHealth)-related factors were evaluated including (1) the presence of health and wellness apps on a tablet or smartphone, (2) use of electronic devices other than tablets and smartphones to monitor health (eg, Fitbit, blood glucose monitor, and blood pressure monitor), and (3) whether people shared health information from an electronic monitoring device or smartphone with a health professional within the last 12 months. Descriptive and inferential statistics were conducted using SAS version 9.4. Weighted population estimates and standard errors, univariate odds ratios, and 95% CIs were calculated, comparing respondents who used tablets or smartphones to help make medical decisions (n=944) with those who did not (n=1377), separately for each factor. Factors of interest with a P value of <.10 were included in a subsequent multivariable logistic regression model. RESULTS:Compared with women, men had lower odds of reporting that a tablet or smartphone helped them make a medical decision. Respondents aged 75 and older also had lower odds of using a tablet or smartphone compared with younger respondents aged 18-34. By contrast, those who had health and wellness apps on tablets or smartphones, used other electronic devices to monitor health, and shared information from devices or smartphones with health care professionals had higher odds of reporting that tablets or smartphones helped them make a medical decision, compared with those who did not. CONCLUSIONS:A limitation of this research is that information was not available regarding the specific health condition for which a tablet or smartphone helped people make a decision or the type of decision made (eg, surgery, medication changes). In US adults, mHealth and eHealth use, and also certain sociodemographic factors are associated with using tablets or smartphones to support medical decision making. Findings from this study may inform future mHealth and other digital health interventions designed to support medical decision making.
