Improving Cardiovascular Health Among African-Americans Through Mobile Health: the FAITH! App Pilot Study

Rationale, design, and participant characteristics of the FAITH! Heart Health+ study: An exploration of the influence of the social determinants of health, stress, and structural racism on African American cardiovascular health

BACKGROUND

African Americans (AAs) face cardiovascular health (CVH) disparities linked to systemic racism. The 2020 police killing of Mr. George Floyd in Minneapolis, Minnesota, alongside the COVID-19 pandemic, exacerbated adverse psychosocial factors affecting CVH outcomes among AAs. This manuscript describes the study protocol and participant characteristics in an ancillary study exploring the relationship between biopsychosocial factors and CVH among AAs.

METHODS

Using a community-based participatory approach, a mixed-methods ancillary study of 58 AA participants from an overarching randomized control trial (RCT) was conducted. Baseline RCT health assessments (November 2020) provided sociodemographic, medical, and clinical data. Subsequent health assessments (February-December 2022) measured sleep quality, psychosocial factors (e.g., high-effort coping), biomarkers (e.g., cortisol), and cardiovascular diagnostics (e.g., cardio-ankle vascular index). CVH was assessed using the American Heart Association Life's Simple 7 (LS7) (range 0 to 14, poor to ideal) and Life's Essential 8 (LE8) scores (range 0 to 100, low to high). Correlations between these scores will be examined. Focus group discussions via videoconferencing (March to April 2022) assessed psychosocial and structural barriers, along with the impact of COVID-19 and George Floyd's killing on daily life.

RESULTS

Participants were predominantly female (67%), with a mean age of 54.6 [11.9] years, high cardiometabolic risk (93% had overweight/obesity and 70% hypertension), and moderate LE8 scores (mean 57.4, SD 11.5).

CONCLUSION

This study will enhance understanding of the associations between biopsychosocial factors and CVH among AAs in Minnesota. Findings may inform risk estimation, patient care, and healthcare policies to address CVD disparities in marginalized populations.

Community Health workers United to Reduce Colorectal cancer and cardiovascular disease among people at Higher risk (CHURCH): study protocol for a randomized controlled trial

BACKGROUND

Colorectal cancer (CRC) is the second most lethal cancer in the United States (U.S.) with the highest incidence and mortality rates among African Americans (AAs) compared to other racial groups. Despite these disparities, AAs are the least likely to undergo CRC screening, have precancerous colorectal polyps removed, and have CRC detected at stages early enough for curative excision. In addition, compelling evidence links inflammatory dietary patterns to increased CRC and cardiovascular disease risk. Studies show that AA churches can successfully engage in health promotion activities including those related to cancer control. The current study seeks to leverage church-placed Community Health Workers (CHWs) to increase CRC screening and reduce CRC risk.

DESIGN AND METHODS

We aim to (1) increase guideline concordant CRC screening uptake using church-placed CHWs trained in screening with a validated instrument, Brief Intervention using Motivational Interviewing, and Referral to Treatment (SBIRT); and (2) reduce dietary risk factors (inflammatory dietary patterns) linked to CRC. The latter will be addressed by culturally adapting an existing, web-based lifestyle program called Alive!. Using a Hybrid Type 1 Implementation-Effectiveness cluster randomized design, we will randomize 22 AA churches into either the dual intervention arm (CHW-led SBIRT intervention plus Alive!) or a usual care arm comprised of CRC prevention educational pamphlets and a list of CRC screening sites. We will recruit 440 subjects and evaluate the effects of both arms on screening uptake (colonoscopy, fecal DNA) (primary outcome) and dietary inflammation score (secondary outcome) at 6-month follow-up, and Life Simple7 (LS7)-a cardiovascular disease (CVD) risk score-at 6 months and 1 year (secondary outcome). Finally, guided by a racism-conscious adaptation of the Consolidated Framework for Implementation Research (CFIR), we will conduct a mixed-methods process evaluation with key stakeholders to understand multi-level influences on CRC screening and CVD risk behaviors.

DISCUSSION

Church-placed CHWs are trusted influential connectors between communities and health systems. Studies have shown that these CHWs can successfully implement health prevention protocols in churches, including those related to cancer control, making them potentially important community mediators of CRC screening uptake and CRC/CVD risk reduction.

Improving mental health in black men through a 24-week community-based lifestyle change intervention: the black impact program

BACKGROUND

Poor mental health is a leading cause of morbidity and mortality among Black men in the United States. Efforts to improve mental health among Black men have been hampered by a lack of access and utilization of mental health services. Physical activity and social networks have been shown to improve mental health. Thus, we examined the effect of a community team-based physical activity, health education and social needs intervention among Black men on mental health over 24 weeks.

METHODS

Black adult males (n = 74) from a large Midwestern city participated in Black Impact, a 24-week community-based lifestyle change program adapted from the Diabetes Prevention Program and American Heart Association's (AHA) Check, Change, Control Blood Pressure Self-Management Program, which incorporates AHA's Life's Simple 7 (LS7) framework. Measures of mental health including the Center for Epidemiological Studies Depression Scale (CES-D), Patient Health Questionnaire 2-question depression screener (PHQ-2), and Perceived Stress Scale-10 (PSS-10) were completed at baseline, 12 and 24 weeks. The change in mental health scores from baseline to 12 and 24 weeks were evaluated using linear mixed-effects models adjusting for age, education, and income. The change in cardiovascular health scores, defined as objective metrics of LS7 (LS5 [blood pressure, total cholesterol, fasting glucose, body mass index and smoking]), by baseline mental health were evaluated using linear mixed-effects models with an interaction term (time*baseline mental health variable) and a random intercept for each participant.

RESULTS

Among 71 Black men (mean age 51, 85% employed) at 24 weeks, CES-D scores decreased from 10.54 to 7.90 (-2.64, 95%CI:-4.74, -0.55), PHQ-2 decreased from 1.04 to 0.63 (-0.41, 95%CI: -0.75, -0.07), and PSS-10 decreased from 14.62 to 12.91 (-1.71, 95%CI: -3.53, 0.12). A 1-unit higher CES-D at baseline was associated with less improvement in LS5 scores by -0.04 (95%CI: -0.076, -0.005) and - 0.032 (95%CI:-0.067, 0.003) units at week 12 and 24, respectively, with similar findings for PSS.

CONCLUSIONS

The Black Impact community-based lifestyle program has the potential to reduce depressive symptoms and stress in Black men. There is a dire need for larger, randomized studies to test the impact of Black Impact on mental health in Black men to advance health equity.

Advancing Equity in Diabetes Prevention, Treatment, and Outcomes: Delivering on Our Values

Diabetes inequities exist from diabetes prevention to outcomes and are rooted in the social drivers (determinants) of health. Historical policies such as "redlining" have adversely affected diabetes prevalence, control, and outcomes for decades. Advancing diabetes equity requires multimodal approaches, addressing both individual-level diabetes education, self-management, and treatment along with addressing social needs, and working to improve upstream drivers of health. All individuals affected by diabetes must advocate for policies to advance diabetes equity at the organizational, local, state, and federal levels. Centering diabetes efforts and interventions on equity will improve diabetes treatment and care for all.

Implementation of Prevention Science to Eliminate Health Care Inequities in Achieving Cardiovascular Health: A Scientific Statement From the American Heart Association

Prevention of cardiovascular and related diseases is foundational to attaining ideal cardiovascular health to improve the overall health and well-being of individuals and communities. Social determinants of health and health care inequities adversely affect ideal cardiovascular health and prevention of disease. Achieving optimal cardiovascular health in an effective and equitable manner requires a coordinated multidisciplinary and multilayered approach. In this scientific statement, we examine barriers to ideal cardiovascular health and its related conditions in the context of leveraging existing resources to reduce health care inequities and to optimize the delivery of preventive cardiovascular care. We systematically discuss (1) interventions across health care environments involving direct patient care, (2) leveraging health care technology, (3) optimizing multispecialty/multiprofession collaborations and interventions, (4) engaging local communities, and (5) improving the community environment through health-related government policies, all with a focus on making ideal cardiovascular health equitable for all individuals.

Decision Trade-Offs in Ecological Momentary Assessments and Digital Wearables Uptake: Protocol for a Discrete Choice Experiment

BACKGROUND

Ecological momentary assessments (EMAs) and digital wearables (DW) are commonly used remote monitoring technologies that capture real-time data in people's natural environments. Real-time data are core to personalized medical care and intensively adaptive health interventions. The utility of such personalized care is contingent on user uptake and continued use of EMA and DW. Consequently, it is critical to understand user preferences that may increase the uptake of EMA and DW.

OBJECTIVE

The study aims to quantify users' preferences of EMA and DW, examine variations in users' preferences across demographic and behavioral subgroups, and assess the association between users' preferences and intentions to use EMA and DW.

METHODS

We will administer 2 discrete choice experiments (DCEs) paired with self-report surveys on the internet to a total of 3260 US adults through Qualtrics. The first DCE will assess participants' EMA preferences using a choice-based conjoint design that will ask participants to compare the relative importance of prompt frequency, number of questions per prompt, prompt type, health topic, and assessment duration. The second DCE will measure participants' DW preferences using a maximum difference scaling design that will quantify the relative importance of device characteristics, effort expectancy, social influence, and facilitating technical, health care, and market factors. Hierarchical Bayesian multinomial logistic regression models will be used to generate subject-specific preference utilities. Preference utilities will be compared across demographic (ie, sex, age, race, and ethnicity) and behavioral (ie, substance use, physical activity, dietary behavior, and sleep duration) subgroups. Regression models will determine whether specific utilities are associated with attitudes toward or intentions to use EMA and DW. Mixture models will determine the associations of attitudes toward and intentions to use EMA and DW with latent profiles of user preferences.

RESULTS

The institutional review board approved the study on December 19, 2022. Data collection started on January 20, 2023, and concluded on May 4, 2023. Data analysis is currently underway.

CONCLUSIONS

The study will provide evidence on users' preferences of EMA and DW features that can improve initial uptake and potentially continued use of these remote monitoring tools. The sample size and composition allow for subgroup analysis by demographics and health behaviors and will provide evidence on associations between users' preferences and intentions to uptake EMA and DW. Limitations include the cross-sectional nature of the study, which limits our ability to measure direct behavior. Rather, we capture behavioral intentions for EMA and DW uptake. The nonprobability sample limits the generalizability of the results and introduces self-selection bias related to the demographic and behavioral characteristics of participants who belong to web-based survey panels.

Community-Based Interventions to Address Disparities in Cardiometabolic Diseases Among Minoritized Racial and Ethnic Groups

PURPOSE OF REVIEW

Cardiometabolic diseases (CMDs) are leading causes of death and disproportionally impact historically marginalized racial/ethnic groups in the United States. The American Heart Association developed the Life's Essential 8 (LE8) to promote optimal cardiovascular health (CVH) through eight health behaviors and health factors. The purpose of this review is to summarize contemporary community-engaged research (CER) studies incorporating the LE8 framework among racial/ethnic groups.

REVIEW OF FINDINGS

Limited studies focused on the interface of CER and LE8. Based on synthesis of articles in this review, the application of CER to individual/collective LE8 metrics may improve CVH and reduce CMDs at the population level. Effective strategies include integration of technology, group activities, cultural/faith-based practices, social support, and structural/environmental changes. CER studies addressing LE8 factors in racial/ethnic groups play an essential role in improving CVH. Future studies should focus on broader scalability and health policy interventions to advance health equity.

An Examination of Culturally Relevant Health Messages in African-American Churches

This quantitative study examined the presence of culturally relevant health messages for African-Americans based on a preexisting dataset from 21 African-American churches in South Carolina (USA). Content analysis served as the primary methodological approach to code printed media messages based on their cultural relevance among African-Americans (Cohen's kappa = .74). Within the dataset (n = 2166), 477 (22%) items were identified as culturally relevant. A low prevalence of culturally relevant messages was found across the three message topics, two media types, and one media source. Due to the limited presence of culturally relevant messages, researchers should collaborate with African-American churches to design health promotion messages.

Mobile Health Intervention to Promote Hypertension Self-Management among African Americans Receiving Care at a Community Health Center: Formative Evaluation of the FAITH! Hypertension App

BACKGROUND

African Americans (AAs) are at a higher risk of premature death from cardiovascular diseases compared to White Americans, with disproportionate attributable risk from uncontrolled hypertension. These health disparities are rooted in structural racism with resultant adverse social determinants of health (SDOH) including limited access to quality healthcare. Given their high usage among AAs, mobile technologies, including smartphones, show promise in increasing access to reliable health information. Thus, culturally tailored mobile health (mHealth) interventions may promote hypertension self-management among this population.

OBJECTIVE

This formative study assessed the feasibility of integrating an innovative mHealth intervention into clinical and community settings to improve blood pressure (BP) control among AAs.

METHODS

A mixed methods study of AA patients with uncontrolled hypertension was implemented over two consecutive phases. In Phase 1, patients and clinicians from two federally qualified health centers (FQHCs) in the Minneapolis-St. Paul, Minnesota metropolitan area provided input through a focus group series to refine an existing culturally tailored mHealth app (FAITH! [Fostering African-American Improvement in Total Health!] App) to promote hypertension self-management among AA patients with uncontrolled hypertension. Phase 2 was a single-arm pre-post intervention pilot study to assess feasibility and patient satisfaction. Patients receiving care at an FQHC participated in a 10-week intervention utilizing the refined FAITH! Hypertension App synchronized with a wireless BP monitor and support from a community health worker (CHW) to address SDOH-related social needs. The multimedia app consisted of a 10-module educational series focused on hypertension and cardiovascular risk factors with interactive self-assessments, medication/BP self-monitoring and social networking. Primary outcomes were feasibility (app engagement/satisfaction) and preliminary efficacy (change in BP) at immediate post-intervention.

RESULTS

In Phase 1, 13 AA patients (69% age ≥50, 77% female) and 16 clinicians (69% age ≥50, 88% female, 63% AA) participated in focus groups. Based on their feedback, app modifications included addition of: BP/medications-tracking, BP self-care task reminders, and culturally sensitive contexts. In Phase 2, 16 AA patients were enrolled (mean age 52.6 years [SD 12.3], 75% female). Of the 16, 38% completed at least half of 10 education modules. Seven of the 16 completed the post-intervention assessment. These patients rated the intervention a 9 (out of 10) as helpful in hypertension self-management. Qualitative data revealed that these patients viewed the app as user-friendly, engaging, and informative, and CHWs were perceived as providing accountability and support. Of the 7 patients, mean systolic and diastolic BPs decreased by 6.4 mmHg (p=.15) and 2.8 mmHg (p=.78) at immediate post-intervention, respectively.

CONCLUSIONS

A culturally tailored mHealth app, with reinforcement by CHW support, may improve hypertension self-management among under-resourced AAs receiving care at FQHCs. A future randomized efficacy trial of the intervention is warranted.

Diversity of Participation in Clinical Trials and Influencing Factors: Findings from the Health Information National Trends Survey 2020

BACKGROUND

Clinical trial diversity is critical to advance health and health equity. Research addressing the discrepancy between goals of achieving clinical trial diversity and realities of study enrollment remains underdeveloped.

OBJECTIVE

This study aims to examine the association between race/ethnicity and clinical trial invitation, participation, knowledge, and sources of influence on clinical trial participation.

DESIGN AND PARTICIPANTS

A cross-sectional, observational study using nationally representative data from 3689 US adults (≥ 18 years of age) who responded to the Health Information National Trends Survey fielded from February 24 to June 15, 2020.

MAIN MEASURES

Primary outcomes included clinical trial invitation, participation, knowledge, and sources of influence on participation. The independent variable of interest is self-reported race/ethnicity.

KEY RESULTS

Respondents identifying as non-Hispanic Black (relative to non-Hispanic White) had higher odds of being invited into a clinical trial (adjusted odds ratio: 2.0, 95% confidence interval (CI): 1.1, 3.7), but no differences in odds of participation were observed by race/ethnicity. Respondents from all races/ethnicities reported that personal healthcare providers were the most trusted source of clinical trial information. Hispanic (marginal effect (ME): - 0.09; 95% CI: - 0.16, - 0.03), non-Hispanic Black (ME: - 0.11; 95% CI: - 0.18, - 0.04), and non-Hispanic other (ME: - 0.11; 95% CI: - 0.19, - 0.02) respondents had lower odds than non-Hispanic White respondents of saying they would be influenced "a lot" by their doctor encouraging participation. Non-Hispanic Black respondents had significantly lower odds (relative to non-Hispanic White) of indicating family encouragement would influence their clinical trial participation decision "a lot" (ME: - 0.09; 95%: CI: - 0.14, - 0.03).

CONCLUSION

While personal healthcare providers were trusted sources of information, racial/ethnic minority populations noted lower odds of clinical trial participation influence from providers and family. Thus, it is imperative for the healthcare, government, and industry organizations to build trust in medicine and science.

Optimizing Prepregnancy Cardiovascular Health to Improve Outcomes in Pregnant and Postpartum Individuals and Offspring: A Scientific Statement From the American Heart Association

This scientific statement summarizes the available preclinical, epidemiological, and clinical trial evidence that supports the contributions of prepregnancy (and interpregnancy) cardiovascular health to risk of adverse pregnancy outcomes and cardiovascular disease in birthing individuals and offspring. Unfavorable cardiovascular health, as originally defined by the American Heart Association in 2010 and revised in 2022, is prevalent in reproductive-aged individuals. Significant disparities exist in ideal cardiovascular health by race and ethnicity, socioeconomic status, and geography. Because the biological processes leading to adverse pregnancy outcomes begin before conception, interventions focused only during pregnancy may have limited impact on both the pregnant individual and offspring. Therefore, focused attention on the prepregnancy period as a critical life period for optimization of cardiovascular health is needed. This scientific statement applies a life course and intergenerational framework to measure, modify, and monitor prepregnancy cardiovascular health. All clinicians who interact with pregnancy-capable individuals can emphasize optimization of cardiovascular health beginning early in childhood. Clinical trials are needed to investigate prepregnancy interventions to comprehensively target cardiovascular health. Beyond individual-level interventions, community-level interventions must include and engage key stakeholders (eg, community leaders, birthing individuals, families) and target a broad range of antecedent psychosocial and social determinants. In addition, policy-level changes are needed to dismantle structural racism and to improve equitable and high-quality health care delivery because many reproductive-aged individuals have inadequate, fragmented health care before and after pregnancy and between pregnancies (interpregnancy). Leveraging these opportunities to target cardiovascular health has the potential to improve health across the life course and for subsequent generations.

A scoping review key elements and effects of cardiovascular disease management programs based on community-based participatory research

BACKGROUND

This scoping review analyses the literature on community-based participatory research (CBPR)-based cardiovascular disease (CVD) management programmes, examining the key elements of their development and implementation and exploring their effectiveness.

METHODS

This scoping review's methodology had six stages: 1) identifying the research question; 2) identifying relevant studies-search strategy; 3) study selection; 4) charting the data; 5) collating, summarising, and reporting the results; and 6) consultation exercise. The databases used were PubMed, Cochrane, and CINAHL, for the period from 4 March to 3 April 2022. We selected studies 1) published after 2000; 2) targeting community residents over 18 years old; and 3) proposed a CBPR-based CVD management programme, described its development, and evaluated its effects based on its application. Data were extracted independently by each of the two researchers, using a standardised form.

RESULTS

Among the key aspects of such programmes were the many cases where community organisations led establishment of partnerships and cases where a decision-making committee was formed. Regarding application of the CBPR principles, community partners participated only in executing the research, not in analysing and interpreting research results. In addition, among the 21 studies selected were 6 randomised controlled trials, all of which showed a significant positive effect in experimental groups compared to control groups.

CONCLUSION

Improvement strategies are needed to allow implementation of CBPR principles in a CBPR-based CVD management programme. Moreover, further verification of programme evaluation research methods is needed.

Cardio oncology: Digital innovations, precision medicine and health equity

The rapid emergence of cardio-oncology has resulted in a rapid growth of cardio-oncology programs, dedicated professional societies sections and committees, and multiple collaborative networks that emerged to amplify the access to care in this new subspecialty. However, most existing data, position statements and guidelines are limited by the lack of availability of large clinical trials to support these recommendations. Furthermore, there are significant challenges regarding proper access to cardio-oncology care and treatment, particularly in marginalized and minority populations. The emergence and evolution of personalized medicine, artificial intelligence (AI), and machine learning in medicine and in cardio-oncology provides an opportunity for a more targeted, personalized approach to cardiovascular complications of cancer treatment. The proper implementation of these new modalities may facilitate a more equitable approach to adequate and universal access to cardio-oncology care, improve health related outcomes, and enable health care systems to eliminate the digital divide. This article reviews and analyzes the current status on these important issues.

Associations of Cardiometabolic Multimorbidity With All-Cause and Coronary Heart Disease Mortality Among Black Adults in the Jackson Heart Study

IMPORTANCE

A combination of diabetes, coronary heart disease (CHD), and stroke has multiplicative all-cause mortality risk compared with any individual morbidity in White populations, but there is a lack of studies in Black populations in the US.

OBJECTIVE

To examine the association of cardiometabolic multimorbidity (diabetes, stroke, and CHD) individually and collectively with all-cause and CHD mortality.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study included Black adults in the Jackson Heart Study followed over a median of 15 years. Baseline examinations were performed between 2000 and 2004, with follow-up on all-cause and CHD mortality through May 31, 2018. Participants were categorized into mutually exclusive groups at baseline: (1) free of cardiometabolic morbidity, (2) diabetes, (3) CHD, (4) stroke, (5) diabetes and stroke, (6) CHD and stroke, (7) diabetes and CHD, and (8) diabetes, stroke, and CHD. Data were analyzed from 2019 to 2021.

EXPOSURE

Cardiometabolic disease alone or in combination.

MAIN OUTCOMES AND MEASURES

The main outcomes were all-cause mortality and CHD mortality. Cox models estimated hazard ratios (HRs) with 95% CIs adjusted for sociodemographic and cardiovascular risk factors.

RESULTS

Among 5064 participants (mean [SD] age, 55.4 [12.8] years; 3200 [63%] women) in the Jackson Heart Study, 897 (18%) had diabetes, 192 (4%) had CHD, and 104 (2%) had a history of stroke. Among participants with cardiometabolic morbidities, the crude all-cause mortality rates were lowest for diabetes alone (24.4 deaths per 1000 person-years) and highest for diabetes, CHD, and stroke combined (84.1 deaths per 1000 person-years). For people with only 1 cardiometabolic morbidity, risk for all-cause mortality was highest for people with stroke (HR, 1.74; 95% CI, 1.24-2.42), followed by CHD (HR, 1.59 (95% CI, 1.22-2.08) and diabetes (HR, 1.50; 95% CI, 1.22-1.85), compared with no cardiometabolic morbidities. There were also increased risks of mortality with combinations of diabetes and stroke (HR, 1.71; 95% CI, 1.09-2.68), CHD and stroke (HR, 2.23; 95% CI, 1.35-3.69), and diabetes and CHD (HR, 2.28; 95% CI, 1.65-3.15). The combination of diabetes, stroke, and CHD was associated with the highest all-cause mortality (HR, 3.68; 95% CI, 1.96-6.93). Findings were similar for CHD mortality, but with a larger magnitude of association (eg, diabetes, stroke, and CHD: HR, 13.52; 95% CI, 3.38-54.12).

CONCLUSIONS AND RELEVANCE

In this cohort study, an increasing number of cardiometabolic multimorbidities was associated with a multiplicative increase in risk of all-cause mortality among Black adults, with a greater magnitude of association for CHD mortality.

Status of Cardiovascular Health in US Adults and Children Using the American Heart Association's New "Life's Essential 8" Metrics: Prevalence Estimates From the National Health and Nutrition Examination Survey (NHANES), 2013 Through 2018

BACKGROUND

The American Heart Association recently published an updated algorithm for quantifying cardiovascular health (CVH)-the Life's Essential 8 score. We quantified US levels of CVH using the new score.

METHODS

We included individuals ages 2 through 79 years (not pregnant or institutionalized) who were free of cardiovascular disease from the National Health and Nutrition Examination Surveys in 2013 through 2018. For all participants, we calculated the overall CVH score (range, 0 [lowest] to 100 [highest]), as well as the score for each component of diet, physical activity, nicotine exposure, sleep duration, body mass index, blood lipids, blood glucose, and blood pressure, using published American Heart Association definitions. Sample weights and design were incorporated in calculating prevalence estimates and standard errors using standard survey procedures. CVH scores were assessed across strata of age, sex, race and ethnicity, family income, and depression.

RESULTS

There were 23 409 participants, representing 201 728 000 adults and 74 435 000 children. The overall mean CVH score was 64.7 (95% CI, 63.9-65.6) among adults using all 8 metrics and 65.5 (95% CI, 64.4-66.6) for the 3 metrics available (diet, physical activity, and body mass index) among children and adolescents ages 2 through 19 years. For adults, there were significant differences in mean overall CVH scores by sex (women, 67.0; men, 62.5), age (range of mean values, 62.2-68.7), and racial and ethnic group (range, 59.7-68.5). Mean scores were lowest for diet, physical activity, and body mass index metrics. There were large differences in mean scores across demographic groups for diet (range, 23.8-47.7), nicotine exposure (range, 63.1-85.0), blood glucose (range, 65.7-88.1), and blood pressure (range, 49.5-84.0). In children, diet scores were low (mean 40.6) and were progressively lower in higher age groups (from 61.1 at ages 2 through 5 to 28.5 at ages 12 through 19); large differences were also noted in mean physical activity (range, 63.1-88.3) and body mass index (range, 74.4-89.4) scores by sociodemographic group.

CONCLUSIONS

The new Life's Essential 8 score helps identify large group and individual differences in CVH. Overall CVH in the US population remains well below optimal levels and there are both broad and targeted opportunities to monitor, preserve, and improve CVH across the life course in individuals and the population.

Religiosity/Spirituality and Cardiovascular Health: The American Heart Association Life's Simple 7 in African Americans of the Jackson Heart Study

Background

Religiosity/spirituality is a major coping mechanism for African Americans, but no prior studies have analyzed its association with the American Heart Association Life's Simple 7 (LS7) indicators in this group.

Methods and Results

This cross‐sectional study using Jackson Heart Study (JHS) data examined relationships between religiosity (religious attendance, private prayer, religious coping) and spirituality (theistic, nontheistic, total) with LS7 individual components (eg, physical activity, diet, smoking, blood pressure) and composite score among African Americans. Multivariable logistic regression assessed the odds of achieving intermediate/ideal (versus poor) LS7 levels adjusted for sociodemographic, behavioral, and biomedical factors. Among the 2967 participants (mean [SD] age=54.0 [12.3] years; 65.7% women), higher religious attendance was associated with increased likelihood (reported as odds ratio [95% CI]) of achieving intermediate/ideal levels of physical activity (1.16 [1.06–1.26]), diet (1.10 [1.01–1.20]), smoking (1.50 [1.34–1.68]), blood pressure (1.12 [1.01–1.24]), and LS7 composite score (1.15 [1.06–1.26]). Private prayer was associated with increased odds of achieving intermediate/ideal levels for diet (1.12 [1.03–1.22]) and smoking (1.24 [1.12–1.39]). Religious coping was associated with increased odds of achieving intermediate/ideal levels of physical activity (1.18 [1.08–1.28]), diet (1.10 [1.01–1.20]), smoking (1.32 [1.18–1.48]), and LS7 composite score (1.14 [1.04–1.24]). Total spirituality was associated with increased odds of achieving intermediate/ideal levels of physical activity (1.11 [1.02–1.21]) and smoking (1.36 [1.21–1.53]).

Conclusions

Higher levels of religiosity/spirituality were associated with intermediate/ideal cardiovascular health across multiple LS7 indicators. Reinforcement of religiosity/spirituality in lifestyle interventions may decrease overall cardiovascular disease risk among African Americans.

Life's Essential 8: Updating and Enhancing the American Heart Association's Construct of Cardiovascular Health: A Presidential Advisory From the American Heart Association

In 2010, the American Heart Association defined a novel construct of cardiovascular health to promote a paradigm shift from a focus solely on disease treatment to one inclusive of positive health promotion and preservation across the life course in populations and individuals. Extensive subsequent evidence has provided insights into strengths and limitations of the original approach to defining and quantifying cardiovascular health. In response, the American Heart Association convened a writing group to recommend enhancements and updates. The definition and quantification of each of the original metrics (Life's Simple 7) were evaluated for responsiveness to interindividual variation and intraindividual change. New metrics were considered, and the age spectrum was expanded to include the entire life course. The foundational contexts of social determinants of health and psychological health were addressed as crucial factors in optimizing and preserving cardiovascular health. This presidential advisory introduces an enhanced approach to assessing cardiovascular health: Life's Essential 8. The components of Life's Essential 8 include diet (updated), physical activity, nicotine exposure (updated), sleep health (new), body mass index, blood lipids (updated), blood glucose (updated), and blood pressure. Each metric has a new scoring algorithm ranging from 0 to 100 points, allowing generation of a new composite cardiovascular health score (the unweighted average of all components) that also varies from 0 to 100 points. Methods for implementing cardiovascular health assessment and longitudinal monitoring are discussed, as are potential data sources and tools to promote widespread adoption in policy, public health, clinical, institutional, and community settings.

Community-Based, Cluster-Randomized Pilot Trial of a Cardiovascular Mobile Health Intervention: Preliminary Findings of the FAITH! Trial

BACKGROUND

African Americans continue to have suboptimal cardiovascular health (CVH) based on the American Heart Association Life's Simple 7 (LS7), 7 health-promoting behaviors and biological risk factors (eg, physical activity, blood pressure). Innovative, community-level interventions in partnership with trusted institutions such as African American churches are potential means to improve CVH in this population.

METHODS

Using a community-based participatory research approach, the FAITH! Trial (Fostering African American Improvement in Total Health) rigorously assessed the feasibility and preliminary efficacy of a refined, community-informed, mobile health intervention (FAITH! App) for promoting CVH among African Americans in faith communities using a cluster randomized controlled trial. Participants from 16 churches in Rochester and Minneapolis-St Paul, MN, were randomized to receive the FAITH! App (immediate intervention) or were assigned to a delayed intervention comparator group. The 10-week intervention core features included culturally relevant and LS7-focused education modules, diet/physical activity self-monitoring, and a group sharing board. Data were collected via electronic surveys and health assessments. Primary outcomes were average change in mean LS7 score (continuous measure of CVH ranging from poor to ideal [0-14 points]) from baseline to 6 months post-intervention (using generalized estimating equations) and app engagement/usability (by the Health Information Technology Usability Evaluation Scale; range, 0-5).

RESULTS

Of 85 enrolled participants (randomized to immediate [N=41] and delayed [control] intervention [N=44] groups), 76 and 68 completed surveys/health assessments at baseline and 6 months post-intervention, respectively (80% retention rate with assessments at both baseline and 6-month time points); immediate intervention [N=30] and control [N=38] groups). At baseline, the majority of participants (mean age [SD], 54.2 [12.3] years, 71% female) had <4-year college education level (39/66, 59%) and poor CVH (44% in poor category; mean LS7 score [SD], 6.8 [1.9]). The mean LS7 score of the intervention group increased by 1.9 (SD 1.9) points compared with 0.7 (SD 1.7) point in the control group (both P<0.0001) at 6 months. The estimated difference of this increase between the groups was 1.1 (95% CI, 0.6-1.7; P<0.0001). App engagement/usability was overall high (100% connection to app; >75% completed weekly diet/physical activity tracking; Health Information Technology Usability Evaluation Scale, mean [SD], 4.2 [0.7]).

CONCLUSIONS

On the basis of preliminary findings, the refined FAITH! App appears to be an efficacious mobile health tool to promote ideal CVH among African Americans.

Disparities in the Use of Cardiac Rehabilitation in African Americans

Purpose of review

Recent findings

Summary

The pursuit of health equity in digital transformation, health informatics, and the cardiovascular learning healthcare system

African Americans have a higher rate of cardiovascular morbidity and mortality and a lower rate of specialty consultation and treatment than Caucasians. These disparities also exist in the care and treatment of chemotherapy-related cardiovascular complications. African Americans suffer from cardiotoxicity at a higher rate than Caucasians and are underrepresented in clinical trials aimed at preventing cardiovascular injury associated with cancer therapies. To eliminate racial and ethnic disparities in the prevention of cardiotoxicity, an interdisciplinary and innovative approach will be required. Diverse forms of digital transformation leveraging health informatics have the potential to contribute to health equity if they are implemented carefully and thoughtfully in collaboration with minority communities. A learning healthcare system can serve as a model for developing, deploying, and disseminating interventions to minimize health inequities and maximize beneficial impact.

Community-based, cluster-randomized pilot trial of a cardiovascular mHealth intervention: Rationale, design, and baseline findings of the FAITH! Trial

BACKGROUND

Compared to whites, African-Americans have lower prevalence of ideal cardiovascular health (CVH) based on the American Heart Association Life's Simple 7 (LS7). These CVH inequities have worsened during the COVID-19 pandemic. Ideal LS7 health-promoting behaviors and biological risk factors (eg, diet, blood pressure) are associated with improved CVH outcomes. The FAITH! (Fostering African-American Improvement in Total Health) App, a community-informed, mobile health (mHealth) intervention, previously demonstrated significant improvements in LS7 components among African-Americans, suggesting that mHealth interventions may be effective in improving CVH. This paper presents the FAITH! Trial design, baseline findings, and pandemic-related lessons learned.

METHODS

Utilizing a community-based participatory research approach, this study assessed the feasibility/preliminary efficacy of a refined FAITH! App for promoting LS7 among African-Americans in faith communities using a cluster, randomized controlled trial. Participants received the FAITH! App (immediate intervention) or were assigned to a delayed intervention comparator group. Baseline data were collected via electronic surveys and health assessments. Primary outcomes are change in LS7 score from baseline to 6-months post-intervention and app engagement/usability.

RESULTS

Of 85 enrolled individuals, 76 completed baseline surveys/health assessments, for a participation rate of 89% (N = 34 randomized to the immediate intervention, N = 42 to delayed intervention). At baseline, participants were predominantly female (54/76, 71%), employed (56/76, 78%) and of high cardiometabolic risk (72/76, 95% with hypertension and/or overweight/obesity) with mean LS7 scores in the poor range (6.8, SD = 1.9).

CONCLUSIONS

The FAITH! Trial recruitment was feasible, and its results may inform the use of mHealth tools to increase ideal CVH among African-Americans.

Applying the Digital Health Social Justice Guide

Introduction

Digital health, the use of apps, text-messaging, and online interventions, can revolutionize healthcare and make care more equitable. Currently, digital health interventions are often not designed for those who could benefit most and may have unintended consequences. In this paper, we explain how privacy vulnerabilities and power imbalances, including racism and sexism, continue to influence health app design and research. We provide guidelines for researchers to design, report and evaluate digital health studies to maximize social justice in health.

Methods

From September 2020 to April 2021, we held five discussion and brainstorming sessions with researchers, students, and community partners to develop the guide and the key questions. We additionally conducted an informal literature review, invited experts to review our guide, and identified examples from our own digital health study and other studies.

Results

We identified five overarching topics with key questions and subquestions to guide researchers in designing or evaluating a digital health research study. The overarching topics are: 1. Equitable distribution; 2. Equitable design; 3. Privacy and data return; 4. Stereotype and bias; 5. Structural racism.

Conclusion

We provide a guide with five key topics and questions for social justice digital health research. Encouraging researchers and practitioners to ask these questions will help to spark a transformation in digital health toward more equitable and ethical research. Future work needs to determine if the quality of studies can improve when researchers use this guide.

Sign of the times: Community engagement to refine a cardiovascular mHealth intervention through a virtual focus group series during the COVID-19 Pandemic

Background

African-Americans are underrepresented in mobile health intervention research studies which can perpetuate health inequities and the digital divide. A community-based, user-centered approach to designing mobile health interventions may increase their sociocultural relevance and effectiveness, especially with increased smartphone use during the coronavirus disease 2019 pandemic. We aimed to refine an existing mobile health intervention via a virtual focus group series.

Methods

African-American community members (n = 15) from churches in Minneapolis-St. Paul and Rochester, Minnesota were enrolled in a virtual (via videoconferencing), three-session focus group series over five months to refine a cardiovascular health-focused mobile health application (FAITH! [Fostering African-American Improvement in Total Health!] App). Participants accessed the app via their smartphones and received a Fitbit synced to the app. Participants engaged with multimedia cardiovascular health-focused education modules, a sharing board for social networking, and diet/physical activity self-monitoring. Participant feedback on app features prompted iterative revisions to the FAITH! App. Primary outcomes were app usability (assessed via Health Information Technology Usability Evaluation Scale range: 0–5) and user satisfaction.

Results

Participants (mean age [SD]: 56.9 [12.3] years, 86.7% female) attended a mean 2.8 focus groups (80% attended all sessions). The revised FAITH! App exceeded the goal Health Information Technology Usability Evaluation Scale score threshold of ≥4 (mean: 4.39, range: 3.20–4.95). Participants positively rated updated app content, visual appeal, and use of social incentives to maintain engagement. Increasing user control and refinement of the moderated sharing board were identified as areas for future improvement.

Conclusions

Community-partnered, virtual focus groups can optimize usability and increase participant satisfaction of mobile health lifestyle interventions that aim to promote cardiovascular health in African-Americans.

Improving Cardiovascular Health in Black Men Through a 24-Week Community-Based Team Lifestyle Change Intervention: The Black Impact Pilot Study

Background

Higher cardiovascular health scores, using American Heart Association's (AHA) Life's Simple 7 (LS7), have been associated with lower risk of cardiovascular disease, type 2 diabetes, cancer, and mortality among all racial/ethnic groups. Nationally, Black men have the lowest levels of LS7. Thus, a study was conducted to evaluate the impact of a community-based team lifestyle change program on LS7 among Black men.

Methods

Black adult males (n = 74) from a large Midwestern city participated in Black Impact, a 24-week community-based team lifestyle change program adapted from the Diabetes Prevention Program and AHA's Check, Change, Control Blood Pressure Self-Management Program, which incorporates AHA's LS7 framework. The change in a LS7 score (range 0–14) from baseline to 12 and 24 weeks was evaluated using a linear mixed-effects model adjusted for age, education, and income.

Results

The mean age of participants was 52 ± 10 years. The men were sociodemographically diverse, with annual income ranging from <$20,000 (7%) to ≥$75,000 (25%). Twenty-five percent were college graduates, 73% had private insurance, and 84% were employed. In fully adjusted models, LS7 score at baseline was 7.12 and increased 0.67 (95%CI: 0.14, 1.20, p = 0.013) and 0.93 (95%CI: 0.40, 1.46, p<0.001) points at 12 and 24 weeks, respectively, compared to baseline. Sensitivity analysis evaluating 5 components (excluding diet and physical activity) and 6 components (excluding diet) also showed significant increases at 12 and 24 weeks (all p<0.01).

Conclusions

The Black Impact lifestyle change single-arm pilot program showed that a community-based lifestyle intervention has the potential to improve LS7 in Black men. Further randomized studies are urgently needed to improve cardiovascular health and advance cardiovascular health equity in Black men.

Association of Cardiovascular Disease Risk Factors With Sociodemographic Characteristics and Health Beliefs Among a Community-Based Sample of African American Adults in Minnesota

OBJECTIVE

To assess cardiovascular disease (CVD) and CVD risk factors and their association with sociodemographic characteristics and health beliefs among African American (AA) adults in Minnesota.

METHODS

A cross-sectional analysis was conducted of a community-based sample of AA adults enrolled in the Minnesota Heart Health Program Ask About Aspirin study from May 2019 to September 2019. Sociodemographic characteristics, health beliefs, and self-reported CVD and CVD risk factors were collected. Prevalence ratio (PR) estimates were calculated using Poisson regression modeling to assess the association between participants' characteristics and age- and sex-adjusted CVD risk factors.

RESULTS

The sample included 644 individuals (64% [412] women) with a mean age of 61 years. Risk factors for CVD were common: hypertension (67% [434]), hyperlipidemia (47% [301]), diabetes (34% [219]), and current cigarette smoking (25% [163]); 19% (119) had CVD. Those with greater perceived CVD risk had a higher likelihood of prevalent hyperlipidemia (PR, 1.34; 95% CI, 1.14 to 1.57), diabetes (PR, 1.61; 95% CI, 1.30 to 1.98), and CVD (PR 1.61; 95% CI, 1.16 to 2.23) compared with those with lower perceived risk. Trust in health care provider was high (83% [535]) but was not associated with CVD or CVD risk factors.

CONCLUSION

In this community sample of AAs in Minnesota, CVD risk factors were high, as was trust in health care providers. Those with greater CVD risk perceptions had higher CVD prevalence. Consideration of sociodemographic and psychosocial influences on CVD and CVD risk factors could inform development of effective cardiovascular health promotion interventions in the AA Minnesota community.

Community-Based Participatory Research to Improve Cardiovascular Health Among US Racial and Ethnic Minority Groups

Purpose of Review

This review aims to assess the contemporary community-based participatory research (CBPR) literature seeking to improve the cardiovascular health of racial and ethnic minority groups in the USA with a higher burden of cardiovascular risk factors and social determinants of health. It summarizes recent CBPR studies based on the American Heart Association Life's Simple 7 (LS7) framework, delineating seven modifiable health behaviors and clinical factors to promote cardiovascular health.

Recent Findings

Although limited in quantity, studies demonstrated preliminary effectiveness in improving individual and a composite of LS7 indicators by employing strategies centered around fortifying social networks, integrating group activities, leveraging technology, incorporating faith-based and spiritual practices, and implementing changes to the built environment.

Summary

Future directions for investigators engaged in CBPR include building on the existing body of evidence through more comprehensive studies, scaling effective interventions, and translating CBPR findings to influence health policy to better address health disparities.

Improving the enrollment of women and racially/ethnically diverse populations in cardiovascular clinical trials: An ASPC practice statement

Cardiovascular disease (CVD) remains the leading cause of death for both women and men worldwide. In the United States (U.S.), there are significant disparities in cardiovascular risk factors and CVD outcomes among racial and ethnic minority populations, some of whom have the highest U.S. CVD incidence and mortality. Despite this, women and racial/ethnic minority populations remain underrepresented in cardiovascular clinical trials, relative to their disease burden and population percentage. The lack of diverse participants in trials is not only a moral and ethical issue, but a scientific concern, as it can limit application of future therapies. Providing comprehensive demographic data by sex and race/ethnicity and increasing representation of diverse participants into clinical trials are essential in assessing accurate drug response, safety and efficacy information. Additionally, diversifying investigators and clinical trial staff may assist with connecting to the language, customs, and beliefs of study populations and increase recruitment of participants from diverse backgrounds. In this review, a working group for the American Society for Preventive Cardiology (ASPC) reviewed the literature regarding the inclusion of women and individuals of diverse backgrounds into cardiovascular clinical trials, focusing on prevention, and provided recommendations of best practices for improving enrollment to be more representative of the U.S. society into trials.

Improvements in Diet and Physical Activity-Related Psychosocial Factors Among African Americans Using a Mobile Health Lifestyle Intervention to Promote Cardiovascular Health: The FAITH! (Fostering African American Improvement in Total Health) App Pilot Study

BACKGROUND

African Americans continue to have suboptimal cardiovascular health (CVH) related to diet and physical activity (PA) behaviors compared with White people. Mobile health (mHealth) interventions are innovative platforms to improve diet and PA and have the potential to mitigate these disparities. However, these are understudied among African Americans.

OBJECTIVE

This study aims to examine whether an mHealth lifestyle intervention is associated with improved diet and PA-related psychosocial factors in African Americans and whether these changes correlate with diet and PA behavioral change.

METHODS

This study is a retrospective analysis evaluating changes in diet and PA-related self-regulation, social support, perceived barriers, and CVH behaviors (daily fruit and vegetable intake and moderate-intensity PA [MPA] per week) in 45 African American adults (mean age 48.7 years, SD 12.9 years; 33/45, 73% women) enrolled in the FAITH! (Fostering African American Improvement in Total Health) app pilot study. The intervention is a 10-week, behavioral theory-informed, community-based mHealth lifestyle intervention delivered through a mobile app platform. Participants engaged with 3 core FAITH! app features: multimedia education modules focused on CVH with self-assessments of CVH knowledge, self-monitoring of daily fruit and vegetable intake and PA, and a sharing board for social networking. Changes in self-reported diet and PA-related self-regulation, social support, perceived barriers, and CVH behaviors were assessed by electronic surveys collected at baseline and 28 weeks postintervention. Changes in diet and PA-related psychosocial factors from pre- to postintervention were assessed using paired 2-tailed t tests. The association of changes in diet and PA-related psychosocial variables with daily fruit and vegetable intake and MPA per week was assessed using Spearman correlation. Associations between baseline and 28-week postintervention changes in diet and PA-related psychosocial measures and CVH behaviors with covariates were assessed by multivariable linear regression.

RESULTS

Participants reported improvements in 2 subscales of diet self-regulation (decrease fat and calorie intake, P=.01 and nutrition tracking, P<.001), one subscale of social support for healthy diet (friend discouragement, P=.001), perceived barriers to healthy diet (P<.001), and daily fruit and vegetable intake (P<.001). Improvements in diet self-regulation (increase fruit, vegetable, and grain intake, and nutrition tracking) and social support for healthy diet (friend encouragement) had moderate positive correlations with daily fruit and vegetable intake (r=0.46, r=0.34, and r=0.43, respectively). A moderate negative correlation was observed between perceived barriers to healthy diet and daily fruit and vegetable intake (r=-0.25). Participants reported increases in PA self-regulation (P<.001). Increase in social support subscales for PA (family and friend participation) had a moderate positive correlation with MPA per week (r=0.51 and r=0.61, respectively).

CONCLUSIONS

Our findings highlight key diet and PA-related psychosocial factors to target in future mHealth lifestyle interventions aimed at promoting CVH in African Americans.

A Review of Disparities in Cardiac Rehabilitation: EVIDENCE, DRIVERS, AND SOLUTIONS

PURPOSE

Cardiac rehabilitation (CR) has been shown to improve functional status, quality of life, and recurrent cardiovascular disease (CVD) events. Despite its demonstrated compelling benefits and guideline recommendation, CR is underutilized, and there are significant disparities in CR utilization particularly by race, ethnicity, sex, and socioeconomic status. The purpose of this review is to summarize the evidence and drivers of these disparities and recommend potential solutions.

METHODS

In this review, key studies documenting disparities in CR referrals, enrollment, and completion are discussed. Additionally, potential mechanisms for these disparities are summarized and strategies are reviewed for addressing them.

SUMMARY

There is a wealth of literature demonstrating disparities among racial and ethnic minorities, women, those with lower income and education attainment, and those living in rural and dense urban areas. However, there was minimal focus on how the social determinants of health contribute to the observed disparities in CR utilization in many of the studies reviewed. Interventions such as automatic referrals, inpatient liaisons, mitigation of economic barriers, novel delivery mechanisms, community partnerships, and health equity metrics to incentivize health care organizations to reduce care disparities are potential solutions.

Association of body image dissatisfaction, behavioral responses for healthy eating, and cardiovascular health in African-American women with overweight or obesity: A preliminary study

BACKGROUND

African-American (AA) women have the lowest prevalence of ideal categorizations of diet and body mass index (BMI), as defined by the American Heart Association (AHA) Life's Simple 7 (LS7) cardiovascular health (CVH) components compared to other racial/ethnic groups, regardless of sex/gender. There is limited research exploring the interplay of unique psychosocial influences on CVH such as body image dissatisfaction (BID) and behavioral responses for healthy eating among AA women with overweight or obesity.

OBJECTIVE

This study aimed to assess the association of BID with behavioral responses for healthy eating and LS7 components.

METHODS

A cross-sectional analysis of baseline data was conducted among 32 AA women with overweight or obesity from a larger, community-based participatory research study. Self-reported measures were used to assess BID and behavioral responses to healthy eating (diet self-regulation to reduce fat or caloric intake and motivation for healthy eating [intrinsic motivation and integrated regulation]) using previously validated instruments. The LS7 components (e.g., BMI, diet, etc.) and composite score were evaluated using the AHA LS7 metrics rubric.

RESULTS

Women with no or lower BID had greater diet self-regulation to reduce fat or caloric intake (mean, 3.5 vs 3.0; P=.05), intrinsic motivation for healthy eating (mean, 5.3 vs 4.2; P=.01), and integrated regulation for healthy eating (mean, 5.3 vs 3.7; P=.002) than those with higher BID. These significant differences remained after adjustment for BMI. Women with higher BID had a higher proportion of BMI within the obesity range compared with those with no or lower BID (94.4% vs 57.1%, P=.03). BID was not significantly associated with other LS7 components or composite score.

CONCLUSION

BID and other psychosocial influences for healthy eating are potential targets for culturally tailored lifestyle interventions among AA women.

Overcoming Historical Barriers: Enhancing Positive Perceptions of Medical Research Among African Americans Through a Conference-Based Workshop

BACKGROUND

African Americans (AAs) and other racial/ethnic minority groups continue to be underrepresented in medical research and clinical trials. Failure to create more racially diverse research cohorts can exacerbate existing health disparities among these groups.

OBJECTIVE

To investigate best practices and strategies for enhancing participation of AAs in medical research among attendees of a preconference Institute at a faith-based public health conference.

DESIGN

Qualitative study using semi-structured interviews.

PARTICIPANTS

A total of 21 out of 29 attendees (90% AA) of the Institute (72% response rate).

APPROACH

A culturally tailored preconference Institute was held at the 2017 Healthy Churches 2020 National Conference. The Institute was led by AA researchers focused on underrepresentation of AAs in medical research. Semi-structured interviews were conducted 1-year post-Institute (n=21) and were audio-recorded, transcribed verbatim, and reviewed using thematic analysis.

KEY RESULTS

The majority of attendees reported that they were more likely to participate in medical research after attending the Institute (75%). Salient learning points reported by attendees demonstrated attainment of the Institute objectives. Key themes emerged describing barriers preventing AAs from participating in medical research including fear/lack of trust, lack of information on research projects, and not being approached to participate. Key themes regarding facilitators for participation in medical research by AAs were clear communication of study objectives and research benefits along with trust in researchers.

CONCLUSIONS

Attendees' perceptions of participation in medical research were largely positive following their attendance at a conference-based Institute aimed to address the underrepresentation of AAs in medical research. Our culturally tailored approach to disseminating knowledge of the research process could extend to other national conferences prioritizing AAs and other racial/ethnic minority populations to improve research participation.

A Cardiovascular Health and Wellness Mobile Health Intervention Among Church-Going African Americans: Formative Evaluation of the FAITH! App

BACKGROUND

In light of the scarcity of culturally tailored mobile health (mHealth) lifestyle interventions for African Americans, we designed and pilot tested the Fostering African-American Improvement in Total Health (FAITH!) App in a community-based participatory research partnership with African American churches to promote cardiovascular health and wellness in this population.

OBJECTIVE

This report presents the results of a formative evaluation of the FAITH! App from participants in an intervention pilot study.

METHODS

We included 2 semistructured focus groups (n=4 and n=5) to explore participants' views on app functionality, utility, and satisfaction as well as its impact on healthy lifestyle change. Sessions were audio-recorded and transcribed verbatim, and qualitative data were analyzed by using general inductive analysis to generate themes.

RESULTS

In total, 6 overarching themes emerged among the 9 participants: overall impression, content usefulness, formatting, implementation, impact, and suggestions for improvement. Underpinning the themes was a high level of agreement that the intervention facilitated healthy behavioral change through cultural tailoring, multimedia education modules, and social networking. Suggestions for improvement were streamlining the app self-monitoring features, prompts to encourage app use, and personalization based on individuals' cardiovascular risk.

CONCLUSIONS

This formative evaluation found that the FAITH! App had high reported satisfaction and impact on the health-promoting behaviors of African Americans, thereby improving their overall cardiovascular health. Further development and testing of the app among African Americans is warranted.

Protocol for a systematic review and meta-analysis of culturally adapted internet- and mobile-based health promotion interventions

INTRODUCTION

High rates of immigration pose challenges for the healthcare systems of many countries to offer high-quality care to diverse populations. Advancing health interventions with incorporating the cultural background of diverse populations can be helpful to overcome this challenge. First studies suggest that culturally diverse populations might benefit from culturally adapted internet-based and mobile-based interventions (IMI) to promote health behaviours. However, the effectiveness of culturally adapted IMIs for health promotion interventions has not been evaluated systematically. Therefore, the aim of this review is to assess the effectiveness of culturally adapted IMIs regarding health promotion. Additionally, the cultural adaptation features of these interventions will be outlined.

METHODS AND ANALYSIS

Randomised controlled trials (RCTs) investigating the effectiveness of culturally adapted IMIs to promote health behaviours in the field of healthy eating, smoking cessation, alcohol consumption, physical activity and sexual health behaviour will be identified via a systematic search of the databases MEDLINE, Embase, PsycINFO, CENTRAL. The preliminary search has been conducted on the 26 August 2019 and will be updated in the process. Data will be pooled meta-analytically in case of at least three included studies reporting on the same outcome. Moreover, a narrative synthesis of the included studies will be conducted. The risk of bias will be assessed using the Cochrane Collaboration's tool for the Quality Assessment of RCTs V. 2.0. Publication bias will be assessed using funnel plots.

ETHICS AND DISSEMINATION

Ethical approval is not required for this study. The results of this study will be published in a peer-reviewed international journal.

Community-engaged and community-based participatory research to promote American Heart Association Life's Simple 7 among African American adults: A systematic review

BACKGROUND

Cardiovascular disease (CVD) is the leading cause of death in the United States and African Americans (AA) have a disproportionately greater burden of CVD as compared to Whites. The American Heart Association (AHA) Life's Simple 7 (LS7) framework outlines goals for attaining ideal cardiovascular health. Yet, there is a lack of evidence summarizing best practices to maximize LS7 attainment. The objective of the present study was to systematically review the extant peer-reviewed literature on community-engaged and community-based participatory research (CBPR) aimed at improving one or more LS7 metrics among AA.

METHODS

PubMed, CINAHL, and Embase databases were searched. We included articles that reported quantitative results for one or more of the following LS7 metrics: physical activity, diet, cholesterol, blood pressure, body mass index, smoking, and glycemia. We included analyses with a greater than 50% AA study population focused on adults (≥18 years of age).

RESULTS

Of the 1008 unique studies identified, 54 met inclusion criteria; 27 of which were randomized controlled trials. 50% of studies assessed more than one LS7 metric but only two studies evaluated all seven of the LS7 metrics. No studies had a high proportion of AA males. 40 studies improved at least one LS7 metric at the study end-point. Formative research was used in many studies to guide intervention design. Studies were of varying quality, but overall rated "fair" using a modified approach to the National Institute of Health quality assessment tool.

CONCLUSION

There is insufficient data to recommend a specific community-engaged or CBPR intervention to improve attainment of LS7 metrics among AA. Future studies using rigorous methodology with increased gender diversity and utilizing the AHA LS7 framework are required to establish a validated program to improve LS7 in AAs.

Continued smoking in African American cancer survivors: The Detroit Research on Cancer Survivors Cohort

Tobacco cessation among those recently diagnosed with cancer is important to improve their prognosis, yet, many cancer survivors continue to smoke. The epidemiology of tobacco use differs by race and ethnicity, and limited cessation research has been conducted in African American (AA) populations. Here, we assess demographic and clinical variables associated with continued smoking in AAs after a cancer diagnosis. The Detroit Research on Cancer Survivors study is a cohort comprised of AA cancer survivors with breast, prostate, lung, and colorectal cancers. Detroit Research on Cancer Survivors data were utilized from survivors who completed their baseline survey within 18 months of cancer diagnosis (n = 1145); 18% (n = 356) reported smoking at the time of cancer diagnosis, and 57% of these (n = 203) continued to smoke after their diagnosis. Logistic regression models were used to assess factors associated with continued smoking. Living with a smoker (odds ratio [OR] = 2.78, 95% confidence interval [CI]: 1.64, 4.70), higher cumulative years of smoking (OR = 1.03, 95% CI: 1.01, 1.05, for each year), and a prostate cancer diagnosis (OR = 7.35, 95% CI: 3.89, 13.89) were all associated with increased odds of continued smoking. Survivors with higher social well-being scores (measured by the Functional Assessment of Cancer Therapy, a quality of life assessment) were more likely to quit smoking after diagnosis (OR = 0.96, 95% CI: 0.93, 1.00). These findings highlight the continued need for personalized cessation strategies to be incorporated into treatment plans for cancer survivors.

Back to the Future: Achieving Health Equity Through Health Informatics and Digital Health

The rapid proliferation of health informatics and digital health innovations has revolutionized clinical and research practices. There is no doubt that these fields will continue to have accelerated growth and a substantial impact on population health. However, there are legitimate concerns about how these promising technological advances can lead to unintended consequences such as perpetuating health and health care disparities for underresourced populations. To mitigate this potential pitfall, it is imperative for the health informatics and digital health scientific communities to understand the challenges faced by disadvantaged groups, including racial and ethnic minorities, which hinder their achievement of ideal health. This paper presents illustrative exemplars as case studies of contextually tailored, sociotechnical mobile health interventions designed with community members to address health inequities using community-engaged research approaches. We strongly encourage researchers and innovators to integrate community engagement into the development of data-driven, modernized solutions for every sector of society to truly achieve health equity for all.
