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.

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.

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.

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.

Genetic testing for the susceptibility to alcohol dependence: interest and concerns in an African American population.

BACKGROUND: The search to identify genes for the susceptibility to alcohol dependence (AD) is generating interest for genetic risk assessment. The purpose of this study is to examine the level of interest and concerns for genetic testing for susceptibility to AD. METHODS: Three hundred four African American adults were recruited through public advertisement. All participants were administered the Genetic Psycho-Social Implication (GPSI) questionnaire, which surveyed their interests in hypothetical genetic testing for AD, as well as their perception of ethical and legal concerns. RESULTS: Over 85% of participants were interested in susceptibility genetic testing; however, persons with higher education (p=0.002) and income (p=0.008) were less willing to receive testing. Perception of AD as a deadly disease (48.60%) and wanting to know for their children (47.90%) were the strongest reasons for interest in testing. Among those not interested in testing, the belief that they were currently acting to lower their risk was the most prevalent. The most widely expressed concern in the entire sample was the accuracy of testing (35.50%). Other notable concerns, such as issues with the method of testing, side effects of venipuncture, falsely reassuring results, and lack of guidelines on "what to do next" following test results, were significantly associated with willingness to receive testing. CONCLUSION: Although an overwhelming majority of participants expressed an interest in genetic testing for AD, there is an understandable high level of methodological and ethical concerns. Such information should form the basis of policies to guide future genetic testing of AD.

Evaluation of the influence of alcohol dehydrogenase polymorphisms on alcohol elimination rates in African Americans.

INTRODUCTION: The relationship between alcohol dehydrogenase (ADH) polymorphisms and alcohol use disorders in populations of African descent has not been clearly established. This study examined the effect of ADH1B polymorphisms on alcohol metabolism and subjective response, following intravenous (IV) alcohol administration, and the influence of gender, recent drinking history, and family history of alcoholism (FHA), in nondependent African American drinkers. MATERIALS: The sample included eighty-seven 21- to 35-year-old, light social drinkers of African descent. Participants included 39 sib pairs, 2 sibships with 3 siblings each, and 3 individuals who were not part of a sibship. Participants received infusions via the use of the clamp method that refers to the goal of controlling breath alcohol concentration in 2 randomized sessions at 0.06 g% ethanol and 0 mg% (placebo), and a battery of subjective scales at predefined time points. Dependent measures included alcohol elimination rates (AERs), alcohol disappearance rates (ADRs), subjective measures peak scores, and area under the curve. General linear model and mixed models were performed to examine the relationship between ADH1B genotype, dependent measures, and influence of covariates. RESULTS: Participants with ADH1B1/1 genotypes showed higher number of drinks (p = 0.023) and drinks per drinking day (p = 0.009) compared with the persons with ADH1B1/3 genotype. AER (adjusted for body weight) was higher in ADH1B*1 homozygotes (p = 0.045) compared with ADH1B1/3 heterozygotes. ADR differed significantly between males and females (p = 0.002), regardless of body weight (p = 0.004) and lean body mass (p < 0.001) adjustments. Although a few subjective measures differed across genotype, all measures were higher in alcohol sessions compared with placebo sessions (p < 0.001). These observations were mediated by drinks per drinking day, gender, and FHA. CONCLUSIONS: ADH1B polymorphism had a marginal effect on alcohol pharmacokinetics following IV alcohol administration in nondependent drinkers of African descent. Session (alcohol vs. placebo) and ADH1B genotype did, however, influence subjective response to alcohol with some variation by gender, FHA, and drinks per drinking day.

Alcohol dependence and health care utilization in African Americans.

OBJECTIVE: Ethnic and cultural differences in patterns of alcohol use disorders must be understood in order to address improvement in prevention of such disorders and accessibility to health care services. The purpose of this study was to evaluate factors that influence the utilization of medical and mental health services among alcohol-dependent and non-alcohol-dependent African Americans. METHOD: A cohort of 454 African Americans was evaluated. Alcohol-dependent participants were recruited from various inpatient treatment facilities in the Washington, DC, metropolitan area and through advertisement and word of mouth. Non-alcohol-dependent participants were recruited by advertisements. Each participant was administered the Semi-Structured Assessment for the Genetics of Alcoholism to assess alcohol dependency and the Family History Assessment module to access family history of alcoholism. Xl Test and analysis of variance were used to analyze the data. RESULTS: Alcohol dependence was more prevalent among men, those with lower income, those with less education, and they utilized mental health counseling as opposed to medical-based therapy. Increased reports of medical conditions such as migraine (p<.001), loss of consciousness (p=.001), and sexually transmitted diseases: (p<.001) were also associated with alcohol dependency. Other factors, including visits to inpatient treatment programs, were directly related to incidence of alcohol dependency regardless of gender status (p<.001). CONCLUSIONS: This study suggests an association exists among alcohol dependence, medical conditions, health care, and mental care utilization among African Americans. Future research may benefit from investigating if an association exists between alcohol use disorders and health care utilization for other ethnic groups.

Screening, brief intervention, and referral to treatment: public health training for primary care.

OBJECTIVES: The purpose of this study was to elucidate changes in attitudes, experiences, readiness, and confidence levels of medical residents to perform screening, brief intervention, and referral to treatment (SBIRT) and factors that moderate these changes. METHODS: A cohort of 121 medical residents received an educational intervention. Self-reported experience, readiness, attitude, and confidence toward SBIRT-related skills were measured at baseline and at follow-up. Analyses were conducted to evaluate the effects of medical specialization. RESULTS: The intervention significantly increased experience (P<.001), attitude (P<.05), readiness (P<.001), and confidence (P<.001). Residents were more likely to report that their involvement influenced patients' substance use. However, experience applying SBIRT skills varied by country of birth, specialty, and baseline scores. CONCLUSIONS: This study suggested that SBIRT training was an effective educational tool that increased residents' sense of responsibility. However, application of skills might differ by specialization and other variables. Future studies are needed to explore and evaluate SBIRT knowledge obtained, within the context of cultural awareness and clinical skills.

Institutional incorporation of screening, brief intervention, and referral to treatment (SBIRT) in residency training: achieving a sustainable curriculum.

The success of implementing a screening, brief intervention and referral to treatment (SBIRT) program within a medical residency program for sustainability is contingent upon a well-crafted training curriculum that incorporates substance abuse education and clinical practice skills. The goal of the Howard University (HU) SBIRT program is to train residents in providing culturally competent evidence-based screening, brief intervention and referral to treatment for patients who have a substance use disorder or who are at risk for developing the disorder. Utilizing the Office of Graduate Medical Education (GME) allows all residents to be trained in SBIRT techniques and receive continuing education in SBIRT and SBIRT-related topics through new resident orientation and the core lecture series. The utilization of Graduate Medical Education office has allowed a robust SBIRT training program to be implemented into medical residency education, contributing to the sustainability of SBIRT as a component of patient care.

Perceptions about genetic testing for the susceptibility to alcohol dependence and other multifactorial diseases.

BACKGROUND: Beliefs, attitudes, and preferences about the risk and benefits of genetic testing are important determinants of willingness to undergo testing. AIMS: The purpose of this study was to evaluate the perceived importance of genetic testing for alcohol dependence compared with other multifactorial diseases among African Americans. METHODS: Surveys were conducted with 258 participants using the Genetic Psycho-Social Implications (GPSI) questionnaire to evaluate several areas of hypothetical genetic testing for alcohol dependence. Respondents were divided into two groups: those who perceived testing for alcohol dependence to be equally important as testing for cancer and those who did not. Using chi-square, the groups' responses were compared for nine GPSI items measuring beliefs about the severity of alcohol dependence, general benefits of genetic testing, and specific benefits of genetic testing for diabetes, hypertension, or a disease affecting a family member. RESULTS: Nearly 86% of respondents believed that genetic testing for alcoholism was equally as important as testing for cancer. Those who reported parity of importance of alcohol dependence and cancer screening were more likely to believe that alcoholism is a deadly disease (p<0.001) and genetic testing influences health (p<0.001). CONCLUSION: African Americans reported favorable attitudes and beliefs in possible availability of susceptibility genetic testing for alcohol dependence. The perceived importance of testing for alcohol dependence was associated with beliefs about the severity of alcoholism and certain benefits of genetic testing in general.
