Community leaders' perspectives on engaging African Americans in biobanks and other human genetics initiatives

Why and how to collect representative study samples in educational neuroscience research

BACKGROUND

Educational neuroscience research, which investigates the neurobiological mechanisms of learning, has historically incorporated samples drawn mostly from white, middle-class, and/or suburban populations. However, sampling in research without attending to representation can lead to biased interpretations and results that are less generalizable to an intended target population. Prior research revealing differences in neurocognitive outcomes both within- and across-groups further suggests that such practices may obscure significant effects with practical implications.

BARRIERS

Negative attitudes among historically marginalized communities, stemming from historical mistreatment, biased research outcomes, and implicit or explicit attitudes among research teams, can hinder diverse participation. Qualities of the research process including language requirements, study locations, and time demands create additional barriers.

SOLUTIONS

Flexible data collection approaches, community engaugement, and transparent reporting could build trust and enhance sampling diversity. Longer-term solutions include prioritizing research questions relevant to marginalized communities, increasing workforce diversity, and detailed reporting of sample demographics. Such concerted efforts are essential for robust educational neuroscience research to maximize positive impacts broadly across learners.

The ethical challenges of diversifying genomic data: A qualitative evidence synthesis

This article aims to explore the ethical issues arising from attempts to diversify genomic data and include individuals from underserved groups in studies exploring the relationship between genomics and health. We employed a qualitative synthesis design, combining data from three sources: 1) a rapid review of empirical articles published between 2000 and 2022 with a primary or secondary focus on diversifying genomic data, or the inclusion of underserved groups and ethical issues arising from this, 2) an expert workshop and 3) a narrative review. Using these three sources we found that ethical issues are interconnected across structural factors and research practices. Structural issues include failing to engage with the politics of knowledge production, existing inequities, and their effects on how harms and benefits of genomics are distributed. Issues related to research practices include a lack of reflexivity, exploitative dynamics and the failure to prioritise meaningful co-production. Ethical issues arise from both the structure and the practice of research, which can inhibit researcher and participant opportunities to diversify data in an ethical way. Diverse data are not ethical in and of themselves, and without being attentive to the social, historical and political contexts that shape the lives of potential participants, endeavours to diversify genomic data run the risk of worsening existing inequities. Efforts to construct more representative genomic datasets need to develop ethical approaches that are situated within wider attempts to make the enterprise of genomics more equitable.

Addressing diversity and inclusion challenges in global neuro-psychiatric and behavioral genomics research

Advancements in neuro-psychiatric and behavioral genomics offer significant opportunities for better understanding the human brain, behavior and associated disorders. Such advancements may help us prevent, manage and/or cure complex conditions. The serious challenge confronted by these disciplines however is diversity. Both fields lack diversity in terms of genomic reference datasets needed for discovery research, engagement of diverse communities in translational research and in terms of diverse and multidisciplinary scientific teams. This is a challenge because diversity is needed on all levels in order to increase representation and inclusion of all populations across the globe as we move research activities forward. The lack of diversity can translate to an inability to use scientific innovations from these fields for the benefit of all people everywhere and signifies a missed opportunity to address pervasive global health inequities. In this commentary we identify three persistent barriers to reaching diversity targets while focusing on discovery and translational science. Additionally, we propose four suggestions on how to advance efforts and rapidly move towards achieving diversity and inclusion in neuro-psychiatric and behavioral genomics. Without systematically addressing the diversity gap within these fields, the benefits of the science may not be relevant and accessible to all people.

Development and Validation of the Perceptions of Research Trustworthiness Scale to Measure Trust Among Minoritized Racial and Ethnic Groups in Biomedical Research in the US

IMPORTANCE

Historically, trust in biomedical research has been lower among minoritized racial and ethnic groups who are underrepresented in and excluded from research, with the same groups experiencing worse health outcomes. Unfortunately, instruments that measure trust may not capture components of trust relevant to minoritized racial and ethnic groups.

OBJECTIVE

To develop and validate a scale to measure trust in biomedical research among minoritized racial and ethnic groups.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional, community-based survey study compared trust and distrust in biomedical research among Black, Latino, and White subgroups in the US using the Perceptions of Research Trustworthiness (PoRT) scale. The scale was developed between March 22, 2016, and September 19, 2018, as part of this study, and its structure, reliability, and validity were examined during pilot (n = 381) and validation (n = 532) phases between February 4, 2019, and July 27, 2021. Convenience samples of adult participants (aged ≥18 years) were recruited locally (Nashville, Tennessee, and San Antonio, Texas) and nationally through the ResearchMatch and Cint online platforms.

MAIN OUTCOMES AND MEASURES

Overall and individual item Trust and Distrust subscale scores were compared. Overall Trust and Distrust scores were compared by race and ethnicity using a Kruskal-Wallis H test and individual item scores were compared using independent samples t test.

RESULTS

Of the 532 participants in the scale validation study, 144 (27.1%) were Black, 90 (16.9%) were Latino, and 282 (53.0%) were White. Participants had a median age of 43 years (range, 18-90 years), 352 (66.2%) were women, and 198 (37.2%) had educational attainment levels less than a college degree. Factor analysis of the 18-item PoRT scale revealed a 2-factor structure with two 9-item PoRT subscales (Trust and Distrust), which demonstrated high internal consistency (Cronbach α = 0.72 and 0.87, respectively). Mean (SD) Trust subscale scores were lower among Black (34.33 [2.02]) and Latino (34.55 [1.97]) participants compared with White participants (36.32 [1.81]; P < .001). Mean (SD) Distrust subscale scores were higher among Black (21.0 [2.15]) and Latino (20.53 [2.21]) participants compared with White participants (18.4 [2.03]; P < .001). Individual item results showed that Black and Latino participants were less trusting and more distrusting than White individuals on items related to risks, harms, secrecy, confidentiality, and privacy.

CONCLUSIONS AND RELEVANCE

These findings suggest that the PoRT scale incorporates trust and trustworthiness concepts relevant among Black and Latino individuals and may allow more precise assessment of trust in research among these groups.

Under-Represented Populations Left Out of Alzheimer's Disease Treatment with Aducanumab: Commentary on Ethics

Despite controversy about the efficacy and safety of aducanumab, the FDA's fast-tracking of this medicine is truly historic. However, structural problems leading to socioeconomic disparities and systemic racism in science, healthcare, and society have left out under-represented populations. This perspective outlines the racial and socioeconomic health disparities in aducanumab treatment: 1) Disparities in the risk of Alzheimer's disease (AD), 2) Limited participation from under-represented groups in AD trials raising concerns about the generalizability of the results, 3) Questionable applicability of the amyloid hypothesis in groups under-represented in AD research, and 4) Aducanumab's initial sticker price that unfairly singled out those with lower socioeconomic backgrounds. Potential solutions are discussed.

Adapting a conceptual framework to engage diverse stakeholders in genomic/precision medicine research

Introduction

Genomic/precision medicine offers a remarkable opportunity to improve health and address health disparities. Genomic medicine is the study of genes and their interaction with health. Precision medicine is an approach to disease prevention and treatment that considers individual variability in genes, environment and lifestyle. Conclusions from studies lacking diversity may hinder generalizability as genomic variation occurs within and between populations. Historical factors, such as medical mistrust, ethical issues related to decision making, and data sharing pose complex challenges that may further widen inequities in genomic/precision medicine if not appropriately addressed. Although few biomedical studies integrate priorities of community partners into their conceptual framework, effective implementation of genomic/precision medicine research calls for the involvement of diverse stakeholders to expand traditional unidirectional models of engagement in clinical research towards authentic bidirectional collaboration.

Methods

A multipronged approach was used integrating an evidence‐based literature review and best practices in developing and evaluating the engagement of diverse stakeholders in genomic and precision medicine research. This was combined with expert consensus building to adapt a conceptual model from a community engagement framework to addressing genomics to be scalable to engagement science, which is challenging to genomic/precision medicine research.

Results

The final enhanced conceptual framework is composed of four overarching dimensions now inclusive of domains in trust, exploitation, discrimination, privacy risk, stigmatization, prior harms/injustices, failure to recognize coexisting governments, intersectionality and research transformation. This conceptual framework proposes effective participant research engagement strategies for upstream relationship building, distinct from downstream recruitment strategies in which the goal is enrolment.

Conclusion

To further shape the evolution of genomic/precision medicine research, it is important to leverage existing partnerships, engage participants beyond recruitment and embrace diverse perspectives.

Patient or Public Contribution

In preparation of this manuscript, the perspectives of the community partners on the impact of engaging in genomic/precision medicine research beyond research participation were integrated into this conceptual framework from various guided listening sessions held in diverse communities.

The Promoting Equity in Stem Cell Genomics Survey

Aim: This study aimed to determine knowledge and attitudes toward induced pluripotent stem cell technology and biobanking. Methods: A survey instrument was developed to determine individuals' knowledge of and attitudes toward these technologies. Results: Results from 276 ethnically diverse participants who took the online survey demonstrated significant associations (p ≤ 0. 05) in knowledge by ethnicity and race regarding properties of stem cells, different types of stem cells and previous sample donation behavior. Significantly more Whites 39% (n = 53) compared with Blacks or African-Americans 19.2% (n = 14) had previous knowledge of induced pluripotent stem cells (χ² = 8.544; p = 0.003) Conclusion: Overall, White race was associated with greater knowledge about stem cells and biobanks and greater willingness to donate samples for future research.

Germline Mutations in African American Men With Prostate Cancer: Incidence, Implications and Diagnostic Disparities

Recent data suggests that African American men (AAM) with prostate cancer (PCa) exhibit genetic alterations in highly penetrant germline genes, as well as low penetrant single nucleotide polymorphisms. The importance of germline variants of uncertain significance (VUS) remain poorly elucidated and given the elevated rates of VUS in AAM compared to Caucasians with PCa, further studies are needed to facilitate potential reclassification of VUS. Ongoing efforts to include AAM in genomics research is of paramount importance in order to ensure applicability of discoveries across diverse populations and potentially reduce PCa disparities as we embark on the era of precision medicine.

Engagement and return of results preferences among a primarily African American genomic sequencing research cohort

Genomics researchers are increasingly interested in what constitutes effective engagement of individuals from underrepresented groups. This is critical for longitudinal projects needed to inform the implementation of precision medicine. Return of results is one opportunity for engagement. The aims of this study were to determine participant perspectives on optimal engagement strategies and priorities for return of results and the extent to which focus groups were an effective modality for gathering input on these topics. We conducted six professionally moderated focus groups with 49 participants in a genomics research study. Transcripts from audio-recorded sessions were coded by two researchers and themes were discussed with the wider research team. All groups raised the issue of mistrust. Individuals participated nonetheless to contribute their perspectives and benefit their community. Many group members preferred engagement modalities that are offered to all participants and allow them to share the nuances of their perspectives over the use of participant representatives and surveys. All groups created a consensus ranking for result return priorities. Results for life-threatening conditions were the highest priority to return, followed by those related to treatable conditions that affect physical or mental health. We advocate for engagement strategies that reach as many participants as possible and allow them to share their perspectives in detail. Such strategies are valued by participants, can be effective for developing return of results policies, and may help institutions become more trustworthy.

Scanning the human genome for "signatures" of positive selection: Transformative opportunities and ethical obligations

The relationship history of evolutionary anthropology and genetics is complex. At best, genetics is a beautifully integrative part of the discipline. Yet this integration has also been fraught, with punctuated, disruptive challenges to dogma, periodic reluctance by some members of the field to embrace results from analyses of genetic data, and occasional over-assertions of genetic definitiveness by geneticists. At worst, evolutionary genetics has been a tool for reinforcing racism and colonialism. While a number of genetics/genomics papers have disproportionately impacted evolutionary anthropology, here we highlight the 2002 presentation of an elegantly powerful approach for identifying "signatures" of past positive selection from haplotype-based patterns of genetic variation. Together with technological advances in genotyping methods, this article transformed our field by facilitating genome-wide "scans" for signatures of past positive selection in human populations. This approach helped researchers test longstanding evolutionary anthropology hypotheses while simultaneously providing opportunities to develop entirely new ones. Genome-wide scans for signatures of positive selection have since been conducted in diverse worldwide populations, with striking findings of local adaptation and convergent evolution. Yet there are ethical considerations with respect to the ubiquity of these studies and the cross-application of the genome-wide scan approach to existing datasets, which we also discuss.

Hmong participants' reactions to return of individual and community pharmacogenetic research results: "A positive light for our community"

Pharmacogenetic research has historically lacked racial and ethnic diversity, limiting the application of findings to minority populations. Recent studies, including the Hmong, have gauged communities' interest in participating in genomic research and receiving their individual results. This study was conducted to create a culturally and linguistically appropriate format to return pharmacogenomic results and identify Minnesota Hmong research participants' reactions to their personal and collective results. Using a community-based participatory research approach, researchers collaborated with Hmong community members to format the pharmacogenetic disclosure process. Three focus groups were completed with 24 Hmong participants and three major themes emerged using thematic analysis. Many Hmong focus group participants viewed the results positively, finding them useful for themselves and their community as a means to optimize responses to and avoid harms from medicines. However, some participants expressed concerns about harms that the pharmacogenetic information could bring, including anxiety, misunderstanding, discrimination, exploitation, and lack of a clinician involvement in interpreting and applying the result. Many participants interpreted their results through an experiential lens, trusting their experience of medicines more than trusting genetic information, and through a cultural lens, expressing the belief that environmental factors may influence how people's bodies respond to medicines by influencing their inherited flesh and blood (roj ntsha). Lastly, participants stressed the importance of disseminating the information while acknowledging the complex linguistic, educational, and cultural factors that limit understanding of the results. Researchers, genetic counselors, pharmacists, and healthcare providers should strive to return results in meaningful ways to all members of society.

Community health advisors assessing adherence to national cancer screening guidelines among African Americans in South Los Angeles

•

Community Health Advisors were able to assess cancer screening in South Los Angeles.

•

About half of African American men and women were up to date with all screening tests.

•

Screening rates in South LA regions are consistent with social determinants of health.

•

Providers should recommend all screening tests to their patients.

•

Our data confirm that South LA is a high priority area for promoting cancer screening.

We partnered with African American churches in South Los Angeles (LA) and trained Community Health Advisors (CHAs) to assess cancer screening. The purpose of this analysis is to report adherence to national cancer screening guidelines among African Americans in South LA, to assess relationships between adherence to colorectal cancer and other cancer screening guidelines, and to explore regional differences in screening rates.

Between 2016 and 2018, 44 CHAs surveyed 777 African Americans between 50 and 75 years of age. Among 420 South LA residents, 64% of men and 70% of women were adherent to colorectal cancer screening guidelines. Adherence to mammography screening guidelines was 73%. Adherence to cervical cancer screening guidelines among women 50 to 65 years of age without hysterectomy was 80%. Fifty-nine percent of men had ever discussed the Prostate Specific Antigen (PSA) test with a physician. Adherence to colorectal cancer screening guidelines was significantly higher among respondents who were adherent to other cancer screening guidelines compared to their peers who were not adherent to other cancer screening guidelines (all p < 0.05). The fact that 22% of women who were adherent to breast cancer screening, 32% of women adherent to cervical cancer screening and 16% of men who had discussed the PSA test with a physician were not adherent to colorectal cancer screening guidelines suggests that providers should redouble their efforts to review all screening guidelines with their patients and to make appropriate recommendations. Regional differences in screening rates within South Los Angeles should inform future screening promotion efforts.

Why African Americans say "No": A Study of Pharmacogenomic Research Participation

Objective

To identify reasons for nonparticipation by African Americans in cardiovascular pharmacogenomic research.

Design

Prospective, open-ended, qualitative survey.

Setting

Research staff approached patients eligible for the Discovery Project of The African American Cardiovascular pharmacogenomics CONsorTium in the inpatient or outpatient setting at four different institutions during September and October 2018.

Participants

Potential Discovery Project participants self-identified as African American, aged >18 years, were on one of five cardiovascular drugs of interest, and declined enrollment in the Discovery Project.

Main Outcome Measures

Reasons for nonparticipation.

Methods

After declining participation in the Discovery Project, patients were asked, "What are your reasons for not participating?" We analyzed their responses using a directed content analytic approach. Ultimately, responses were coded into one of nine categories and analyzed using descriptive statistics.

Results

Of the 194 people approached for the Discovery Project during an eight-week period, 82 declined participation and provided information for this study. The most common reason for refusal was concern about the amount of blood drawn (19.5%). The next most common reasons for refusal to participate included concerns about genetic testing (14.6%) and mistrust of research (12.2%). Across study sites, significantly more patients enrolled in the inpatient than outpatient setting (P<.001). Significantly more women and younger individuals declined participation due to concerns about genetic testing and too little compensation (P<.05).

Conclusions

Collection of blood samples and concerns about genetic testing are obstacles for the recruitment of African Americans to pharmacogenomics studies. Efforts to overcome these barriers to participation are needed to improve representation of minorities in pharmacogenomic research. Enrolling participants from inpatient populations may be a solution to bolster recruitment efforts.

Exploring African American community perspectives about genomic medicine research: A literature review

Genomic medicine research is an important topic in the African American health care community. African American nurses and advance practice nursing professionals are poised to encourage and educate themselves and their communities about the importance of diversity in genomic medicine research. The Southern Nevada Black Nurses Association, a chapter within the larger National Black Nurses Association’s, recently engaged in the National Institutes of Health All of Us research program to educate their members about formularies and other treatment modalities that could clinically benefit African-Americans and other populations of color. During this event, the Southern Nevada Black Nurses Association discovered that National Black Nurses Association members held ethical, legal, and social concerns about engaging in genomic medicine research that align with respective concerns reported in the literature. In this review, we discuss National Black Nurses Association concerns and how they relate to qualitative themes emerging from the literature and a recent National Academies of Science, Engineering, and Medicine event on disparities in access to genomic medicine. We conclude that researchers should engage with African American health community leaders to effectively engage the African American community in genomic medicine research and help ensure that genomic medicine does not exacerbate existing health disparities.

A Review of African Americans' Beliefs and Attitudes About Genomic Studies: Opportunities for Message Design

Precision Medicine, the practice of targeting prevention and therapies according to an individual’s lifestyle, environment or genetics, holds promise to improve population health outcomes. Within precision medicine, pharmacogenomics (PGX) uses an individual’s genome to determine drug response and dosing to tailor therapy. Most PGX studies have been conducted in European populations, but African Americans have greater genetic variation when compared with most populations. Failure to include African Americans in PGX studies may lead to increased health disparities. PGX studies focused on patients of African American descent are needed to identify relevant population specific genetic predictors of drug responses. Recruitment is one barrier to African American participation in PGX. Addressing recruitment challenges is a significant, yet potentially low-cost solution to improve patient accrual and retention. Limited literature exists about African American participation in PGX research, but studies have explored barriers and facilitators among African American participation in genomic studies more broadly. This paper synthesizes the existing literature and extrapolates these findings to PGX studies, with a particular focus on opportunities for message design. Findings from this review can provide guidance for future PGX study recruitment.

Attitudes and experiences regarding genetic research among persons of African descent

Minorities are underrepresented in genetic research. This study examined the attitudes, experiences, and willingness of persons of African descent related to participation in genetic research. A total of 272 persons of African descent completed a questionnaire about attitudes and experiences associated with genetic research. Descriptive, Chi-square, and logistic regression were used to examine the impact of attitudes and experiences in predicting the odds of willingness to participate in genetic research. A majority of participants (97%) indicated that they have never participated in genetic research; however, a majority also reported that they would be willing to participate in a genetic study specifically for the detection of risk factors for cancer (87%), diabetes (89%), alcohol use disorder (73%), and Alzheimer's disease (88%). Participants who disagreed that "results from genetic research can explain why some diseases are found more often in some ethnic groups than others" were less likely to be willing to participate in studies related to cancer (OR = 0.16), diabetes (OR = .16), alcohol use disorder (OR = 0.27), and Alzheimer's disease (OR = 0.27). Participants reported limited experiences engaging in genetic research; yet, they overwhelmingly acknowledged the importance of genetic research and expressed willingness to participate in multifactorial genetic studies despite concerns about genetic discrimination, stigma, and/or a potentially poor prognosis. Further research on the underlying reasons why persons of African descent choose to participate in genetic research should be explored and addressed to make research more inclusive and ethically sound.

Successful recruitment and retention of diverse participants in a genomics clinical trial: a good invitation to a great party

PURPOSE

African ancestry (AA) individuals are inadequately included in translational genomics research, limiting generalizability of findings and benefits of genomic discoveries for populations already facing disproportionately poor health outcomes. We aimed to determine the impact of stakeholder-engaged strategies on recruitment and retention of AA adult patients into a clinical trial testing them for renal risk variants nearly exclusive to AAs.

METHODS

Our academic-clinical-community team developed ten key strategies that recognize AAs' barriers and facilitators for participation. Using electronic health records (EHRs), we identified potentially eligible patients. Recruiters reached out through letters, phone calls, and at medical visits.

RESULTS

Of 5481 AA patients reached, 51% were ineligible, 37% enrolled, 4% declined, 7% were undecided when enrollment finished. We retained 93% at 3-month and 88% at 12-month follow-up. Those enrolled are more likely female, seen at community sites, and reached through active strategies, than those who declined. Those retained are more likely female, health-literate, and older. While many patients have low income, low clinician trust, and perceive racism in health care, none of these attributes correlate with retention.

CONCLUSION

With robust stakeholder engagement, recruiters from patients' communities, and active approaches, we successfully recruited and retained AA patients into a genomic clinical trial.

Sistas Taking a Stand for Breast Cancer Research (STAR) Study: A Community-Based Participatory Genetic Research Study to Enhance Participation and Breast Cancer Equity among African American Women in Memphis, TN

African American women are substantially underrepresented in breast cancer genetic research studies and clinical trials, yet they are more likely to die from breast cancer. Lack of trust in the medical community is a major barrier preventing the successful recruitment of African Americans into research studies. When considering the city of Memphis, TN, where the percentage of African Americans is significantly higher than the national average and it has a high rate of breast cancer mortality inequities among African American women, we evaluated the feasibility of utilizing a community-based participatory (CBPR) approach for recruiting African American women into a breast cancer genetic study, called the Sistas Taking A Stand for Breast Cancer Research (STAR) study. From June 2016 and December 2017, African American women age 18 and above were recruited to provide a 2 mL saliva specimen and complete a health questionnaire. A total of 364 African American women provided a saliva sample and completed the health questionnaire. Greater than 85% agreed to be contacted for future studies. Educational workshops on the importance of participating in cancer genetic research studies, followed by question and answer sessions, were most successful in recruitment. Overall, the participants expressed a strong interest and a willingness to participate in the STAR study. Our findings highlight the importance of implementing a CBPR approach that provides an educational component detailing the importance of participating in cancer genetic research studies and that includes prominent community advocates to build trust within the community.

Bridging the Data Gap in Breast Cancer Risk Assessment to Enable Widespread Clinical Implementation across the Multiethnic Landscape of the US

Breast cancer remains the second leading cause of cancer death among women and is the most commonly diagnosed cancer in women. Breast cancer risk assessment has been clinically available for nearly 30 years yet is under-utilized in practice for multiple reasons. Incorporation of polygenic risk as well as breast density measurements, promise to increase the accuracy of risk assessment. With that comes the hope that both prevention and screening become more personalized and thus more effective. Incidence rates have been static over the past 15 years and have even increased slightly in African American and Asian/Pacific Islander populations despite the robust data on breast cancer risk reduction measures that exist. Current challenges in reducing breast cancer incidence begin with robust data curation that allows for appropriate risk stratification across our multiethnic population and conclude with the implementation of prevention strategies within our fractured healthcare system.

Linking Education to Action: A Program to Increase Research Participation Among African American Women

BACKGROUND

Underrepresentation of African American women as research participants contributes to health disparities. Contemporary studies have focused on clinical trial (CT) participation; epidemiologic and genetic studies utilizing medical records and/or biological samples have received less attention. In partnership with The Links, Incorporated (The Links), a national service organization of professional African American women, this study sought to examine attitudes regarding chart review (CR) studies, genetic studies/biobanking (GEN), and CTs; develop; and evaluate an online education-to-action program.

METHODS

In phase 1, focus groups were convened with members of The Links to inform the content and format of the program. Phases 2 and 3 involved designing and evaluating the program, respectively.

RESULTS

Thirty-four women across three focus groups shared attitudes and perceptions regarding research and provided guidance for program development. Subsequently, 244 women completed the program (77% response rate), including pre- and post-assessments. Participants indicating that they "definitely" or "probably" (responses combined) intend to participate in research increased from 36.5% to 69.3% (pre/post-program). Agreement with the statement "research in the U.S. is ethical" increased (52.9% to 74.4%) as did factual knowledge regarding each of the study types. There was a decrease in reporting "little or no understanding" of study types (Pre/Post: GEN: 66%/24.9%, CR: 62.9%/18.4%, CTs: 40.7%/15.5%). Pre-program, few were "very positive" about the study types (14.3% GEN, 15.0% CR, 28.6% CTs); post-program ratings increased and equalized (42.8% GEN, 43.0% CR, 42.5% CTs).

CONCLUSIONS

An online education-to-action program targeting professional African American women improved knowledge, perceptions of ethics, and intent to participate in biomedical research.

Beyond Consent: Building Trusting Relationships With Diverse Populations in Precision Medicine Research

With the growth of precision medicine research on health data and biospecimens, research institutions will need to build and maintain long-term, trusting relationships with patient-participants. While trust is important for all research relationships, the longitudinal nature of precision medicine research raises particular challenges for facilitating trust when the specifics of future studies are unknown. Based on focus groups with racially and ethnically diverse patients, we describe several factors that influence patient trust and potential institutional approaches to building trustworthiness. Drawing on these findings, we suggest several considerations for research institutions seeking to cultivate long-term, trusting relationships with patients: (1) Address the role of history and experience on trust, (2) engage concerns about potential group harm, (3) address cultural values and communication barriers, and (4) integrate patient values and expectations into oversight and governance structures.

African American Women's Perspectives on Donating Healthy Breast Tissue for Research: Implications for Recruitment

African American women die of breast cancer at a higher rate than any other racial group. The Komen Tissue Bank (KTB) is an ongoing clinical trial that collects healthy breast tissue from women of all racial groups to use as controls in research and represents a critical tool in efforts to treat and prevent breast cancer; however, African Americans display reticence toward donating breast tissue to the KTB. Through the lens of the Integrated Behavioral Model, this study recruited African American women to share their perspectives on donating breast tissue for research purposes. Seventy-one (N = 71) eligible Black women who were previous tissue donors to the KTB responded to an online questionnaire. Findings revealed that (a) participants had positive instrumental attitudes or reasons for donating; (b) participants felt generally supported in their decision to donate, but revealed that the lack of Black women participating in the KTB meant that they themselves were setting the norm for others; and (c) their race was an important element in their donation decision. While acknowledging the negative history of African Americans in medical research, they offered their perceptions regarding the importance of involving themselves in medical research, and suggested that health communication strategies to recruit African Americans into research should embrace race as part of the message. The findings from this study have important implications for other those who work in applied clinical settings and are interested in addressing racial disparities in medical research through more effective and targeted recruitment messaging.

Review: Genetic research on alcohol use outcomes in African American populations: A review of the literature, associated challenges, and implications

BACKGROUND AND OBJECTIVES

There have been remarkable advances in understanding genetic influences on complex traits; however, individuals of African descent have been underrepresented in genetic research.

METHODS

We review the limitations of existing genetic research on alcohol phenotypes in African Americans (AA) including both twin and gene identification studies, possible reasons for underrepresentation of AAs in genetic research, the implications of the lack of racially diverse samples, and special considerations regarding conducting genetic research in AA populations.

RESULTS

There is a marked absence of large-scale AA twin studies so little is known about the genetic epidemiology of alcohol use and problems among AAs. Individuals of African descent have also been underrepresented in gene identification efforts; however, there have been recent efforts to enhance representation. It remains unknown the extent to which genetic variants associated with alcohol use outcomes in individuals of European and African descent will be shared. Efforts to increase representation must be accompanied by careful attention to the ethical, legal, and social implications of genetic research. This is particularly true for AAs due to the history of abuse by the biomedical community and the persistent racial discrimination targeting this population.

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

Lack of representation in genetic studies limits our understanding of the etiological factors that contribute to substance use and psychiatric outcomes in populations of African descent and has the potential to further perpetuate health disparities. Involving individuals of diverse ancestry in discussions about genetic research will be critical to ensure that all populations benefit equally from genetic advances. (Am J Addict 2017;26:486-493).

Learning from Latino voices: Focus Groups' Insights on Participation in Genetic Research

BACKGROUND AND OBJECTIVES

There is a paucity of genetics research examining alcohol use among Latinos. The purpose of this study is to examine Latino perceptions of participation in alcohol studies that collect biological samples, an important precursor to increasing their participation in genetics research.

METHODS

A synthesis of the literature addressing participation of racial/ethnic minorities in alcohol genetics research was undertaken. We developed a framework of themes related to barriers and facilitators for participation, which we then used to analyze two focus groups held with 18 Latino participants.

RESULTS

From the literature review, we identified nine themes related to facilitators of and barriers to participation. They are, on continua: curiosity to disinterest; trust to mistrust; understanding to confusion; safety to danger; inclusion to exclusion; sense of connection to disconnection; hope to despair; ease to hassle; and benefit to cost. Another theme emerged from the focus groups: previous experience to no previous experience with health research.

CONCLUSIONS

Applying the themes from the literature review to Latino perspectives on providing biological samples for alcohol research helps expand their definition and applicability. Consideration of these themes when designing recruitment/retention materials and strategies may encourage Latino participation in alcohol genetics research.

SCIENTIFIC SIGNIFICANCE

An understanding of these themes and their significance for Latinos is offered in the form of "guiding questions" for researchers to consider as we strive for more inclusive research. Focus group participants were Mexican American; future research should further explore perspectives of this heterogeneous demographic group by studying other Latino subgroups. (Am J Addict 2017;26:477-485).

Leaves imitate trees: Minnesota Hmong concepts of heredity and applications to genomics research

Historically, Hmong refugees in the USA were distrustful of Western medicine, medicines, and medical research due to concerns about harm and experimentation. Current Hmong concerns about genomics research are not well known. Our research aims were to identify cultural and ethical issues about conducting genomic studies in the Hmong community. Using a community-based participatory action process, the West Side Hmong Genomics Research Board conducted a qualitative exploratory research study that included semistructured interviews with five Hmong key informants and five focus groups with 42 Hmong adults near Saint Paul, Minnesota. We used a thematic analysis approach to qualitatively analyze the data. Identified concepts of heredity included characteristics that are passed between the generations: physical features; character traits; some behaviors; some diseases; and probably not response to medicines, although individual variations to medicines are known. Most participants were willing to join genomic research projects to help themselves and community. Others refused to participate: they did not want to know future disease risk; did not want doctors to know their genes; did not trust doctors with their blood; and did not know if they would benefit from results. Ethically, many participants were in favor of confidentiality, but wanted to know their personal results; many were willing to agree to genetic storage of anonymous samples; all agreed with individual consent, not family or community consent; and none were concerned about social stigma from genetic testing about chronic diseases and medications. The Hmong Genomics Board will build upon these concepts to create, conduct, and evaluate culturally-appropriate genomic and pharmacogenomic research projects relevant to community interests.

Towards a more representative morphology: clinical and ethical considerations for including diverse populations in diagnostic genetic atlases

An important gap exists in textbooks (or atlases) of dysmorphology used by health-care professionals to help diagnose genetic syndromes. The lack of varied phenotypic images in available atlases limits the utility of these atlases as diagnostic tools in globally diverse populations, causing geneticists difficulty in diagnosing conditions in individuals of different ancestral backgrounds who may present with variable morphological features. Proposals to address the underinclusion of images from diverse populations in existing atlases can take advantage of the Internet and digital photography to create new resources that take into account the broad global diversity of populations affected by genetic disease. Creating atlases that are more representative of the global population will expand resources available to care for diverse patients with these conditions, many of whom have been historically underserved by the medical system. However, such projects also raise ethical questions that are grounded in the complex intersection of imagery, medicine, history, and race and ethnicity. We consider here the benefits of producing such a resource while also considering ethical and practical concerns, and we offer recommendations for the ethical creation, structure, equitable use, and maintenance of a diverse morphological atlas for clinical diagnosis.Genet Med 18 11, 1069-1074.

Genome-wide association studies in Africans and African Americans: expanding the framework of the genomics of human traits and disease

Genomic research is one of the tools for elucidating the pathogenesis of diseases of global health relevance and paving the research dimension to clinical and public health translation. Recent advances in genomic research and technologies have increased our understanding of human diseases, genes associated with these disorders, and the relevant mechanisms. Genome-wide association studies (GWAS) have proliferated since the first studies were published several years ago and have become an important tool in helping researchers comprehend human variation and the role genetic variants play in disease. However, the need to expand the diversity of populations in GWAS has become increasingly apparent as new knowledge is gained about genetic variation. Inclusion of diverse populations in genomic studies is critical to a more complete understanding of human variation and elucidation of the underpinnings of complex diseases. In this review, we summarize the available data on GWAS in recent African ancestry populations within the western hemisphere (i.e. African Americans and peoples of the Caribbean) and continental African populations. Furthermore, we highlight ways in which genomic studies in populations of recent African ancestry have led to advances in the areas of malaria, HIV, prostate cancer, and other diseases. Finally, we discuss the advantages of conducting GWAS in recent African ancestry populations in the context of addressing existing and emerging global health conditions.

Enhancing the participation of african americans in health-related genetic research: findings of a collaborative academic and community-based research study

The involvement of African Americans in research has long been expressed as a concern by the scientific community. While efforts have been undertaken to identify factors inhibiting the participation of African Americans in health-related research, few efforts have been undertaken to have highlight factors associated with their engagement of health-related research. An exploratory study of factors presumed to be associated with participation in health-related research was conducted among a nonprobability sample of African Americans (n = 212) from a large urban community in the Midwest. The study was guided by a framework that hypothesized the influence of knowledge, beliefs, and perceptions about genetics and the involvement of providers in decision-making on willingness to participate in health-related genetic research. The results revealed that knowledge, beliefs, and perceptions about genetics and the involvement of providers were associated with willingness to engage in health-related genetic research (P < .05). The most interesting, however, was that 88.7% of the participants who had not previously been involved in a health-related study who expressed a willingness to participate reported that they "had never been asked." Study findings suggest the need for research that further examines factors associated with the involvement of African Americans in health-related genetic research.
