Social Determinants of Health Research at NIMHD: An Analysis of Studies Funded During 2019-2023.

INTRODUCTION: Social determinants of health (SDOH) contribute to differences in health outcomes and exacerbate health disparities. This study characterizes the National Institute on Minority Health and Health Disparities' (NIMHD) portfolio of funded grants in SDOH research, identifies gaps, and provides suggestions for future research. METHODS: Using the National Institutes of Health's SDOH Research, Condition, and Disease Categorization, research projects funded from 2019 to 2023 were identified and linked with NIMHD's internal coding system to extract in-depth study characteristics, including sociodemographics of study participants, disease and condition focus, and alignment with strategic priorities. Natural Language Processing methods were used to categorize projects into five Healthy People 2030 SDOH domains. RESULTS: The resulting sample included 675 unique research projects. Most projects included racial and ethnic minority groups (89%), followed by people with lower socioeconomic status (33%), underserved rural communities (16%), and sexual and gender minority groups (13%). Most projects focused on the Etiology of health disparities (61%), followed by Interventions (54%), and Methods and Measurement (39%). Of the Healthy People 2030 domains, Social and Community Context had the greatest representation (61%) whereas Education Access and Quality had the least (6%). Variation in research project characteristics across SDOH domains is also presented. CONCLUSIONS: This study documents characteristics of SDOH research funded by NIMHD and explores how they differ across Healthy People 2030 SDOH domains. Findings highlight how study characteristics and foci align with strategic priorities and suggest opportunities for future research.

The PhenX Toolkit: Recommended Measurement Protocols for Social Determinants of Health Research.

Health disparities are driven by unequal conditions in the environments in which people are born, live, learn, work, play, worship, and age, commonly termed the Social Determinants of Health (SDoH). The availability of recommended measurement protocols for SDoH will enable investigators to consistently collect data for SDoH constructs. The PhenX (consensus measures for Phenotypes and eXposures) Toolkit is a web-based catalog of recommended measurement protocols for use in research studies with human participants. Using standard protocols from the PhenX Toolkit makes it easier to compare and combine studies, potentially increasing the impact of individual studies, and aids in comparability across literature. In 2018, the National Institute on Minority Health and Health Disparities provided support for an initial expert Working Group to identify and recommend established SDoH protocols for inclusion in the PhenX Toolkit. In 2022, a second expert Working Group was convened to build on the work of the first SDoH Working Group and address gaps in the SDoH Toolkit Collections. The SDoH Collections consist of a Core Collection and Individual and Structural Specialty Collections. This article describes a Basic Protocol for using the PhenX Toolkit to select and implement SDoH measurement protocols for use in research studies. © 2024 The Authors.

Understanding the Changing Landscape of Health Disparities in Chronic Liver Diseases and Liver Cancer.

Liver disease and liver cancer disparities in the U.S. are reflective of complex multiple determinants of health. This review describes the disproportionate burden of liver disease and liver cancer among racial, ethnic, sexual, and gender minority, rural, low socioeconomic status (SES) populations, and place-based contexts. The contributions of traditional and lifestyle-related risk factors (e.g., alcohol consumption, evitable toxin exposure, nutrition quality) and comorbid conditions (e.g., viral hepatitis, obesity, type II diabetes) to disparities is also explored. Biopsychosocial mechanisms defining the physiological consequences of inequities underlying these health disparities, including inflammation, allostatic load, genetics, epigenetics, and social epigenomics are described. Guided by the National Institute on Minority Health and Health Disparities (NIMHD) framework, integrative research of unexplored social and biological mechanisms of health disparities, appropriate methods and measures for early screening, diagnosis, assessment, and strategies for timely treatment and maintaining multidisciplinary care should be actively pursued. We review emerging research on adverse social determinants of liver health, such as structural racism, discrimination, stigma, SES, rising care-related costs, food insecurity, healthcare access, health literacy, and environmental exposures to pollutants. Limited research on protective factors of liver health is also described. Research from effective, multilevel, community-based interventions indicate a need for further intervention efforts that target both risk and protective factors to address health disparities. Policy-level impacts are also needed to reduce disparities. These insights are important, as the social contexts and inequities that influence determinants of liver disease/cancer have been worsened by the coronavirus disease-2019 pandemic and are forecasted to amplify disparities.

Examining Alcohol Interventions Across the Lifespan among the African Diaspora: A Systematic Review.

AIMS: Racial/ethnic and cultural identity influences alcohol use consumption and help-seeking behaviors. The purpose of this systematic review was to assess alcohol prevention programs and interventions targeting African Americans/Blacks among the African Diaspora across the lifespan. METHODS: According to PRISMA guidelines, literature searches were conducted via electronic databases, grey literature, and hand searches of relevant journal articles evaluating primary outcome data to reduce alcohol use. To be included in this systematic review, intervention and prevention studies required a population of more than 50% African descent and provided information about statistical significance (p < .05) indicating changes in alcohol as a primary outcome. RESULTS: Search strategy identified 5691 citations and the full-text of 148 studies were screened. A total of 23 articles met the inclusion criteria. Studies were geographically located in the United States and African countries. Interventions were implemented in community, patient-care, school, and workplace settings. Adult studies evaluated pharmacological and/or behavioral interventions while utilizing validated instruments and procedures to assess alcohol outcomes. Strategies to change alcohol behavior included psychotherapy, brief motivational interviewing (BMI), and counseling. Adolescent studies utilized family-based, computer-assisted technology, and career development interventions to reduce alcohol use. CONCLUSIONS: The systematic review identified a range of intervention articles addressing the reduction of alcohol use for African Americans/Blacks that may be used in various settings and by different age groups. Best practices and strategies designed to address socio-cultural factors by promoting protective and risk-reducing factors of alcohol use and successful alcohol interventions are needed.

Signatures of functional bacteriome structure in a tropical direct-developing amphibian species.

BACKGROUND: Host microbiomes may differ under the same environmental conditions and these differences may influence susceptibility to infection. Amphibians are ideal for comparing microbiomes in the context of disease defense because hundreds of species face infection with the skin-invading microbe Batrachochytrium dendrobatidis (Bd), and species richness of host communities, including their skin bacteria (bacteriome), may be exceptionally high. We conducted a landscape-scale Bd survey of six co-occurring amphibian species in Brazil's Atlantic Forest. To test the bacteriome as a driver of differential Bd prevalence, we compared bacteriome composition and co-occurrence network structure among the six focal host species. RESULTS: Intensive sampling yielded divergent Bd prevalence in two ecologically similar terrestrial-breeding species, a group with historically low Bd resistance. Specifically, we detected the highest Bd prevalence in Ischnocnema henselii but no Bd detections in Haddadus binotatus. Haddadus binotatus carried the highest bacteriome alpha and common core diversity, and a modular network partitioned by negative co-occurrences, characteristics associated with community stability and competitive interactions that could inhibit Bd colonization. CONCLUSIONS: Our findings suggest that community structure of the bacteriome might drive Bd resistance in H. binotatus, which could guide microbiome manipulation as a conservation strategy to protect diverse radiations of direct-developing species from Bd-induced population collapses.

COVID-19 Health Disparities and Adverse Social Determinants of Health.

Racial and ethnic disparities in healthcare and health outcomes are longstanding. The real-time emergence of COVID-19 disparities has heightened the public and scientific discourse about structural inequities contributing to the greater risk of morbidity and mortality among racial and ethnic minority populations and other underserved groups. A key aspect of assuring health equity is addressing social determinants that lead to adverse health outcomes among minoritized groups. This article presents an exploratory social determinants of health (SDOH) conceptual framework for understanding racial and ethnic COVID-19 disparities, including factors related to health and healthcare, socioeconomics, and environmental determinants. The model also illustrates the backdrop of structural racism and discrimination, which directly affect health and COVID-19 exposure risk, and thus transmission, infection, and death. We also describe a special SDOH collection in the PhenX Toolkit (consensus measures for Phenotypes and eXposures), which includes established measures to promote standardization of assessment and the use of common data elements in research contexts. The use of common constructs, measures, and data elements are important for data integration, understanding the causes of health disparities, and evaluating interventions to reduce them. Substandard SDOH are among the primary drivers of health disparities-and scientific approaches to address these key concerns require identification and leveled alignment with the root causes. The overarching goal of this discussion is to broaden the consideration of mechanisms by which populations with health disparities face additional SARS-CoV-2 exposure risks, and to encourage research to develop interventions to reduce SDOH-associated disparities in COVID-19 and other conditions and behaviors.

Healthcare providers experiences with shared medical appointments for heart failure.

Shared medical appointments (SMAs) offer a means for providing knowledge and skills needed for chronic disease management to patients. However, SMAs require a time and attention investment from health care providers, who must understand the goals and potential benefits of SMAs from the perspective of patients and providers. To better understand how to gain provider engagement and inform future SMA implementation, qualitative inquiry of provider experience based on a knowledge-attitude-practice model was explored. Semi-structured interviews were conducted with 24 health care providers leading SMAs for heart failure at three Veterans Administration Medical Centers. Rapid matrix analysis process techniques including team-based qualitative inquiry followed by stakeholder validation was employed. The interview guide followed a knowledge-attitude-practice model with a priori domains of knowledge of SMA structure and content (understanding of how SMAs were structured), SMA attitude/beliefs (general expectations about SMA use), attitudes regarding how leading SMAs affected patients, and providers. Data regarding the patient referral process (organizational processes for referring patients to SMAs) and suggested improvements were collected to further inform the development of SMA implementation best practices. Providers from all three sites reported similar knowledge, attitude and beliefs of SMAs. In general, providers reported that the multi-disciplinary structure of SMAs was an effective strategy towards improving clinical outcomes for patients. Emergent themes regarding experiences with SMAs included improved self-efficacy gained from real-time collaboration with providers from multiple disciplines, perceived decrease in patient re-hospitalizations, and promotion of self-management skills for patients with HF. Most providers reported that the SMA-setting facilitated patient learning by providing opportunities for the sharing of experiences and knowledge. This was associated with the perception of increased comradery and support among patients. Future research is needed to test suggested improvements and to develop best practices for training additional sites to implement HF SMA.

Responding to healthcare distrust among underserved communities: Phase II.

OBJECTIVE: Medical distrust is both a psychosocial construct and an underappreciated individual social determinant of health with the potential to affect oncology care and clinical trial participation. A community-based participatory research effort, called the Forward Movement Project (FMP), identified multilevel factors affecting trust for healthcare and research in an underserved urban community. In FMP Phase II, we implemented a community-responsive approach to provide lay-oriented education and address misinformation, with the goal of beginning to remediate distrust for healthcare systems and biomedical research. METHODS: Community residents (N = 154 adults, 64% male, M = 61.5 years old, 53% annual income <$10,000, 83% African American/Black) engaged in participant-driven dialogues with oncology clinicians/clinical researchers and support services professionals. A program evaluation focused on trust for healthcare and biomedical research. RESULTS: Participants reported positive evaluations of both the program and the cancer center clinicians and staff, who were rated as trustworthy (80% strong agreement). However, trust for healthcare systems ("Strongly agree" = 58%) and medical researchers ("Strongly agree" = 50%) following the program was moderate. Over half of the sample (52%) strongly agreed they would participate in a clinical trial compared to before joining this study. CONCLUSION: Findings supported the user-generated program approach. The FMP is an example of a model for true community engaged research and has implications for rebuilding trust in healthcare and research.

Habitat Disturbance Linked with Host Microbiome Dispersion and Bd Dynamics in Temperate Amphibians.

Anthropogenic habitat disturbances can dramatically alter ecological community interactions, including host-pathogen dynamics. Recent work has highlighted the potential for habitat disturbances to alter host-associated microbial communities, but the associations between anthropogenic disturbance, host microbiomes, and pathogens are unresolved. Amphibian skin microbial communities are particularly responsive to factors like temperature, physiochemistry, pathogen infection, and environmental microbial reservoirs. Through a field survey on wild populations of Acris crepitans (Hylidae) and Lithobates catesbeianus (Ranidae), we assessed the effects of habitat disturbance and connectivity on environmental bacterial reservoirs, Batrachochytrium dendrobatidis (Bd) infection, and skin microbiome composition. We found higher measures of microbiome dispersion (a measure of community variability) in A. crepitans from more disturbed ponds, supporting the hypothesis that disturbance increases stochasticity in biological communities. We also found that habitat disturbance limited microbiome similarity between locations for both species, suggesting greater isolation of bacterial assemblages in more disturbed areas. Higher disturbance was associated with lower Bd prevalence for A. crepitans, which could signify suboptimal microclimates for Bd in disturbed habitats. Combined, our findings show that reduced microbiome stability stemming from habitat disturbance could compromise population health, even in the absence of pathogenic infection.

The Focus They Deserve: Improving Women Veterans' Health Care Access.

PURPOSE: Veterans Health Administration (VHA) initiatives aim to provide veterans timely access to quality health care. The focus of this analysis was provider and staff perspectives on women veterans' access in the context of national efforts to improve veterans' access to care. METHODS: We completed 21 site visits at Veterans Health Administration medical facilities to evaluate the implementation of a national access initiative. Qualitative data collection included semistructured interviews (n = 127), focus groups (n = 81), and observations with local leadership, administrators, providers, and support staff across primary and specialty care services at each facility. Deductive and inductive content analysis was used to identify barriers, facilitators, and contextual factors affecting implementation of initiatives and women veterans' access. RESULTS: Participants identified barriers to women veterans' access and strategies used to improve access. Barriers included a limited availability of providers trained in women's health and gender-specific care services (e.g., women's specialty care), inefficient referral and coordination with community providers, and psychosocial factors (e.g., childcare). Participants also identified issues related to childcare and perceived harassment in medical facility settings as distinct access issues for women veterans. Strategies focused on increasing internal capacity to provide on-site women's comprehensive care and specialty services by streamlining provider training and credentialing, contracting providers, using telehealth, and improving access to community providers to fill gaps in women's services. Participants also highlighted efforts to improve gender-sensitive care delivery. CONCLUSIONS: Although some issues affect all veterans, problems with community care referrals may disproportionately affect women veterans' access owing to a necessary reliance on community care for a range of gender-specific services.

Superwomen and Sleep: an Assessment of Black College Women Across the African Diaspora.

BACKGROUND: Women and racial/ethnic minority groups in the U.S. report poor sleep health. While stress and alcohol use may contribute to sleep problems, few studies have examined the roles of stress and alcohol use on sleep among Black college women. Gender-racial ideology of Black womanhood may also play a role in sleep. This exploratory study sought to examine the relationships between stress, alcohol, ethnic-gender identity, and sleep. METHOD: Guided by the biopsychosocial model and intersectionality theory, a cross-sectional study design recruited undergraduate women (18-24 years) attending a Historically Black College and University (HBCU) who self-identified as Black (N = 110). Participants completed the Insomnia Severity Index, Pittsburgh Sleep Quality Index, Perceived Stress Scale, Alcohol Use Disorders Test, and Giscombe Superwoman Schema Questionnaire. Univariate and multiple linear regressions were conducted to examine independent and multiple effects of stress, alcohol, and ethnic-gender identity on insomnia and sleep quality. RESULTS: Participants (mean age 19.4 years) represented diverse ethnic groups, 53% American, 25% African, and 20% Caribbean. Nearly 23% reported moderate to severe levels of insomnia. Scores from the Perceived Stress Scale, the Alcohol Use Disorders Test, and the Giscombe Superwoman Schema Questionnaire were independently associated with insomnia and sleep quality. In multivariate analyses, only perceived stress exhibited a significant association with insomnia and sleep quality. CONCLUSION: This exploratory study demonstrated that stress, excessive alcohol use, and ethnic-gender identity have relational impact on sleep health. Yet, stress may have greater importance and further research is needed to explore factors that mediated the relationship between stress and sleep.

Understanding Multilevel Factors Related to Urban Community Trust in Healthcare and Research.

BACKGROUND: Community and patient engagement in the healthcare system and biomedical research are prerequisites for eliminating health disparities. We conducted a "listening tour" to enhance our understanding of multilevel factors associated with community trust. METHODS: Using community-based participatory research (CBPR) methods, we conducted a phenomenological qualitative study. "Town-hall" style discussions were held at nine sites across an urban, Midwestern city. We recruited adults (N = 130) via community networks, social media, flyers, and word-of-mouth. Demographic assessments were self-administered and listening tour sessions were conducted by trained moderators. Themes were framed within the social ecological model (SEM; intrapersonal, interpersonal, institutional, community, and policy levels). RESULTS: Participants were mostly female (68%), African American (80%), had health coverage (97%) and were diagnosed with a chronic health condition (71%). The overarching theme was sociodemographic differences in distrust, such that African Americans and deaf/hearing impaired participants perceived disparities in healthcare, a lower quality of care, and skepticism about biomedical research, relative to Whites. CONCLUSIONS: The depth of distrust for healthcare providers, systems, and researchers in underserved communities remains strong and complex. Findings highlight the need to understand the lived experiences of community members, and how distrust is maintained. Multilevel interventions to increase trust and the accrual of underrepresented populations into clinical trials are needed.

Group medical visits after heart failure hospitalization: Study protocol for a randomized-controlled trial.

A primary goal of this research project is to better understand how shared medical appointments (SMAs) can improve the health status and decrease hospitalization and death for patients recently discharged with heart failure (HF) by providing education, disease state monitoring, medication titration, and social support to patients and their caregivers. We propose a 3-site randomized-controlled efficacy trial with mixed methods to test a SMA intervention, versus usual care. Patients within 12 weeks of a HF hospitalization will be randomized to receive either HF-SMA (intervention arm) with optional co-participation with their caregivers, versus usual care (control arm). The HF-SMA will be provided by a non-physician team composed of a nurse, a nutritionist, a health psychologist, a nurse practitioner and/or a clinical pharmacist and will consist of four sessions of 2-h duration that occur every other week for 8 weeks. Each session will start with an assessment of patient needs followed by theme-based disease self-management education, followed by patient-initiated disease management discussion, and conclude with break-out sessions of individualized disease monitoring and medication case management. The study duration will be 180 days for all patients from the day of randomization. The primary study hypothesis is that, compared with usual care, patients randomized to HF-SMA will experience better cardiac health status at 90 and 180 days follow-up. The secondary hypotheses are that, compared to usual care, patients randomized to HF-SMA will experience better overall health status, a combined endpoint of hospitalization and death, better HF self-care behavior, and lower B-type natriuretic peptide levels.

Drugs and life-threatening ventricular arrhythmia risk: results from the DARE study cohort.

OBJECTIVES: To establish a unique sample of proarrhythmia cases, determine the characteristics of cases and estimate the contribution of individual drugs to the incidence of proarrhythmia within these cases. SETTING: Suspected proarrhythmia cases were referred by cardiologists across England between 2003 and 2011. Information on demography, symptoms, prior medical and drug histories and data from hospital notes were collected. PARTICIPANTS: Two expert cardiologists reviewed data for 293 referred cases: 130 were included. Inclusion criteria were new onset or exacerbation of pre-existing ventricular arrhythmias, QTc >500 ms, QTc >450 ms (men) or >470 ms (women) with cardiac syncope, all secondary to drug administration. Exclusion criteria were acute ischaemia and ischaemic polymorphic ventricular tachycardia at presentation, structural heart disease, consent withdrawn or deceased prior to study. Descriptive analysis of Caucasian cases (95% of included cases, n=124) and culpable drug exposures was performed. RESULTS: Of the 124 Caucasian cases, 95 (77%) were QTc interval prolongation-related; mean age was 62 years (SD 15), and 63% were female. Cardiovascular comorbidities included hypertension (53%) and patient-reported 'heart rhythm problems' (73%). Family history of sudden death (36%) and hypokalaemia at presentation (27%) were common. 165 culpable drug exposures were reported, including antiarrhythmics (42%), of which amiodarone and flecainide were the most common. Sotalol, a beta-blocking agent with antiarrhythmic activity, was also common (15%). 26% reported multiple drugs, of which 84% reported at least one cytochrome (CYP) P450 inhibitor. Potential pharmacodynamics interactions identified were mainly QT prolongation (59%). CONCLUSIONS: Antiarrhythmics, non-cardiac drugs and drug combinations were found to be culpable in a large cohort of 124 clinically validated proarrhythmia cases. Potential clinical factors that may warn the prescriber of potential proarrhythmia include older women, underlying cardiovascular comorbidity, family history of sudden death and hypokalaemia.

Using Qualitative Methods to Understand Perceptions of Risk and Condom Use in African American College Women: Implications for Sexual Health Promotion.

BACKGROUND: Young African American women are disproportionately affected with sexually transmitted infections (STIs) and unintentional pregnancies. Despite adequate knowledge, assertiveness, and negotiation skills, consistent condom use remains low. AIMS: We sought to assess the role of pregnancy and STI risk perception in condom decision making among African American women. METHOD: We conducted a phenomenological qualitative study. Utilizing a purposive sampling strategy, 100 African American women (18-24 years) were recruited from a historically Black college and university for an open discussion of condom use. Thirteen focus groups were conducted via a semistructured interview guide and analyzed with an inductive thematic approach. RESULTS: Uniformly women perceived pregnancy as a greater threat than STIs which appears to be maintained by (a) their sense of fertility, (b) self-care concept, and (c) experiences with condom failure. Thus, women were skeptical about using condoms as a form of contraception. Women perceived casual sex as having the greatest HIV/STI risk and emphasized the importance of assertiveness and self-respect to negotiate condom use. However, condom use in monogamous relationships is less likely due to (a) testing/knowing partner's status, (b) relationship trust, and (c) the use of hormonal contraception for pregnancy prevention. Perceived threat of infidelity increases condom use. CONCLUSION: The implications of these findings suggest sexual health promotion programs may focus on improving women's estimate of the effectiveness of condoms to prevent pregnancy and addressing women's reliance on testing for STI prevention.

Beliefs and Preferences for Medical Research Among African-Americans.

BACKGROUND AND OBJECTIVES: Numerous factors contribute to underrepresentation of African-Americans in medical research, including beliefs, historical events, structural, and health access obstacles. This study examined beliefs about medical research and the types of study methods preferred among potential African-American research participants. METHODS: A sample of 304 African-American participants from the Washington, DC Metropolitan area, completed a survey evaluating beliefs about medical research and preferred research study methods. Multiple Regression analyses were performed to examine how age, gender, and education may influence these beliefs and preferences for research study methods. RESULTS: The beliefs and preferences surveyed did not differ by age, gender, or educational attainment. There was an overwhelmingly favorable belief (90 %) that medical research was necessary and assists in finding a cure for a disease. Most respondents preferred participating in research related to issues with which they were familiar (e.g., diabetes, hypertension) or working with researchers of a similar ethnic background to themselves. Interestingly, though nonsignificant, those with higher levels of educational trended toward the belief that participation in research was risky. CONCLUSION: The findings of this study indicate that certain beliefs about medical research participation and preferred study methodologies reported by African-Americans did not differ by age, gender, or level of education. This information about African-American's beliefs and preferences regarding medical research should lead to an awareness of potential gains in African-American participation through the development of culturally sensitive medical research studies and methodologies.

Minority College Women's Views on Condom Negotiation.

This study utilized quantitative and qualitative methods to (1) investigate the relationship between frequency of condom use and negotiation strategies and (2) evaluate experiences with condom negotiations among sexually active, heterosexual, African American college women. One hundred female students from a Historically Black Colleges and Universities (HBCU) completed a questionnaire that included the Condom Influence Strategies Scale (CIS) and participated in a focus group. An ANOVA was conducted to compare differences between never, inconsistent, and consistent condom users. Consistent condom users scored higher than never users on the "withholding sex" subscale of the CIS (4.88 vs. 3.55; p < 0.001) as well as endorsed items more strongly on the "direct request" subscale of the CIS (4.63 vs. 3.82, p < 0.05) than never users. A thematic analysis of open discussions identified overarching themes. Similarly, refusing sex and/or having direct communications with partner emerged as primary strategies. Threats to negotiation included deciding the "right timing" of discussion and having a previous history of sexual intercourse without a condom with their partner. Other key concepts that contribute to condom negotiation are the views that condoms are a male's responsibility and stigma of women who carry condoms.
