Development and Testing of the WiseApp for Improving Medication Adherence Among Spanish Speakers.

There is evidence to support the use of mHealth tools for improving medication adherence. Building on this evidence, our study team culturally adapted and translated the WiseApp for improving antiretroviral medication adherence in Spanish-speaking persons with HIV. We are currently conducting a multi-site randomized controlled trial (RCT) to test the effectiveness and sustainability of the WiseApp for Spanish speakers in New York City and the Dominican Republic.

Using Natural Language Processing on Expert Panel Discussions to Gain Insights for Recruitment, Retention and Intervention Adherence for Online Social Support Interventions on a Stage II-III Clinical Trial Among Hispanic and African American Dementia Caregivers.

We applied natural language processing (NLP) to a corpus extracted from 4 hours of expert panel discussion transcripts to determine the sustainability of a Stage II-III clinical trial of online social support interventions for Hispanic and African American dementia caregivers. Prominent topics included Technology/hard to reach populations, Training younger populations, Building trust, Privacy and security issues, Simplification of screening questions and recruitment procedures, Understanding participants' needs, Planning strategies and logistics, Potential recruitment places, Adjusting intervention size downwards to engage elderly participants, Targeting different generations, Internet-based interventions by age range, and Providing step-by-step instructions and an overview of the entire research process during recruitment. The application of NLP to qualitative data on a dementia caregiving clinical trial provides useful insights for recruitment, retention, and adherence to guidelines for such interventions serving Hispanic and African American dementia caregivers.

Characterization of Ptau181 Among a Diverse Community-Based Cohort: A HABS-HD Study.

Background: Examination of Alzheimer's disease (AD) related biomarkers among diverse communities has remained limited. Objective: The aim of this study was to expand on prior work to provide a characterization of ptau181 among a diverse community sample. Consideration was taken regarding the impact of comorbidities on ptau181 levels including medical. Methods: 3,228 (n = 770 African American [AA], n = 1,231 Hispanic, and n = 1,227 non-Hispanic white [NHW]) Health and Aging Brain Study- Health Disparities (HABS-HD) participants were included in this study. ANCOVAs were conducted to examine differences in ptau181 levels across race and ethnic groups. Violin plots were also generated stratified by APOEɛ4 carrier status, Amyloid PET positivity status, medical comorbidity (hypertension, dyslipidemia, chronic kidney disease [CKD], and diabetes) and by cognitive diagnosis. Results: Ptau181 levels were found to differ between Hispanics and NHW after covarying for age, sex, and APOEɛ4 status. Amyloid PET positivity was associated with higher ptau181 levels across all groups. APOEɛ4 positivity status was only significantly associated with ptau181 levels among AAs. Across all race and ethnic groups, those with a diagnosis of CKD had higher levels of ptau181. When stratified by cognitive diagnosis, cognitively unimpaired Hispanics had higher ptau181 if they also had a diagnosis of CKD or diabetes. p-values ≤0.01. Conclusions: Differences in ptau181 levels were shown in a diverse community sample. Medical comorbidities had a differing effect on ptau181 levels particularly among Hispanics even without cognitive impairment. Findings support the need for future work to consider comorbid conditions when examining the utility of ptau181.

Peer Influence on Motivation to Use Pre-Exposure Prophylaxis Among Latino Sexual Minority Men in Miami, Florida: A Network Autocorrelation Model.

Despite the availability of pre-exposure prophylaxis (PrEP), Latino sexual minority men (LSMM) continue to experience disparities in PrEP uptake and subsequently, HIV vulnerability. Social network norms are an underutilized solution to increase PrEP uptake. We used a peer influence model (network autocorrelation model) to examine the role of social network descriptive norms (i.e., actual behaviors) surrounding PrEP use. A total of 11 sociocentric networks of 13 friends (n = 143 LSMM) were recruited into our study from 2018 to 2019 in South Florida. Most participants were in PrEP pre-contemplation (n = 44), and almost one-third of our sample were using PrEP (n = 38). Three network autocorrelation models were estimated using an empirically informed Bayesian analysis. We found a positive association between participants' Motivational PrEP Cascade (MPC) position and their network members' (friends') cascade position based on three different measures of connection even when accounting for PrEP knowledge: friendship (ρ = 0.22; 95% CIa = 0.01-0.42), emotional closeness (ρ = 0.24; 95% CI = 0.03-0.44), and frequency of interaction (ρ = 0.22; CI = 0.03-0.42). Our findings highlight that an individual's progress in the MPC may be influenced by their network members' progress in the MPC, suggesting that LSMM using PrEP may serve as role models to their peers for PrEP use due to descriptive norms. Our findings further suggest that PrEP interventions for LSMM along the MPC can be implemented at the social network level.

Through the eyes of Spanish-speaking patients, caregivers, and community leaders: a qualitative study on the in-patient hospital experience.

BACKGROUND: Spanish-speakers with non-English language preference and complex medical needs suffer disparities in quality of care, safety, and health outcomes. Communication challenges during prolonged hospitalizations for complex illnesses negatively influence how this group engages in their care and decision-making while hospitalized. Limited literature capturing the perspectives of Spanish-speaking patients in this context exists. Given the impact of language barriers on care and medical decision-making, this study documents the experiences of Spanish-speaking patients with NELP and hospitalized with complex care needs as well as caregivers and community leaders. METHODS: Using community-engaged recruitment strategies and semi-structured interviews and a focus group, we gathered insights from Spanish-speaking patients hospitalized for prolonged periods, caregivers, and community leaders from three geographic regions. Data were deidentified, transcribed, translated, coded in duplicate, and analyzed guided by grounded theory using NVivo. RESULTS: We interviewed 40 participants: 27 patients, 10 caregivers and 3 community leaders. We identified four major themes: (1) Disconnected experiences impeding interactions, communication, and decision-making (2) Inadequate interpreter services (3) Benefits and consequences of family at the bedside (4) Community -informed recommendations. CONCLUSION: The study showed that in-person interpreters were preferred to virtual interpreters; yet interpreter access was suboptimal. This resulted in ad hoc family interpretation. Participants noted language negatively impacted patient's hospital experience, including decreasing confidence in medical decision-making. Recommendations from patients, caregivers, and community leaders included expanding interpreter access, bolstering interpreter quality and accuracy, and increasing resources for patient education.

Parent Experiences of Empowerment: Understanding the Role of Parent Empowerment in Child Health Promotion.

BACKGROUND: Establishing healthy behaviors during a child's first 5 years is essential for healthy growth. Parents are targeted as agents of change because they serve as primary models of behavior during this period. Although parent-focused interventions often target empowerment as a driver of change, our understanding of how parents experience the process of empowerment in the context of child health promotion remains limited. OBJECTIVE: This qualitative study explored the process by which parents gain empowerment through participation in a health promotion intervention. METHODS: Semi-structured interviews were conducted with 37 low-income parents who participated in Parents Connect for Healthy Living (PConnect), a 10-week empowerment-centered obesity prevention intervention. Data were analyzed using inductive-deductive thematic analysis and guided by empowerment theories. RESULTS: Most parents were Hispanic/Latino (41%) and female (97%). Five themes emerged that correspond to the process by which parents gained empowerment: (1) friendships formed and relationships strengthened during PConnect, (2) parents strengthened relationships with their children and believed in their ability to parent successfully, (3) the experience of knowledge led to behavior change, (4) parents used new resources to improve family health, and (5) parents took action. CONCLUSION: Empowerment theory should be a component of health promotion programs.

Epigenetic and genetic risk of Alzheimer disease from autopsied brains in two ethnic groups.

Genetic variants and epigenetic features both contribute to the risk of Alzheimer's disease (AD). We studied the AD association of CpG-related single nucleotide polymorphisms (CGS), which act as a hub of both the genetic and epigenetic effects, in Caribbean Hispanics (CH) and generalized the findings to Non-Hispanic Whites (NHW). First, we conducted a genome-wide, sliding-window-based association with AD, in 7,155 CH and 1,283 NHW participants. Next, using data from the dorsolateral prefrontal cortex in 179 CH brains, we tested the cis- and trans-effects of AD-associated CGS on brain DNA methylation to mRNA expression. For the genes with significant cis- and trans-effects, we investigated their enriched pathways. We identified six genetic loci in CH with CGS dosage associated with AD at genome-wide significance levels: ADAM20 (Score = 55.19, P = 4.06 × 10-8), the intergenic region between VRTN and SYNDIG1L (Score = - 37.67, P = 2.25 × 10-9), SPG7 (16q24.3) (Score = 40.51, P = 2.23 × 10-8), PVRL2 (Score = 125.86, P = 1.64 × 10-9), TOMM40 (Score = - 18.58, P = 4.61 × 10-8), and APOE (Score = 75.12, P = 7.26 × 10-26). CGSes in PVRL2 and APOE were also significant in NHW. Except for ADAM20, CGSes in the other five loci were associated with CH brain methylation levels (mQTLs) and CGSes in SPG7, PVRL2, and APOE were also mQTLs in NHW. Except for SYNDIG1L (P = 0.08), brain methylation levels in the other five loci affected downstream mRNA expression in CH (P < 0.05), and methylation at VRTN and TOMM40 were also associated with mRNA expression in NHW. Gene expression in these six loci were also regulated by CpG sites in genes that were enriched in the neuron projection and glutamatergic synapse pathways (FDR < 0.05). DNA methylation at all six loci and mRNA expression of SYNDIG1 and TOMM40 were significantly associated with Braak Stage in CH. In summary, we identified six CpG-related genetic loci associated with AD in CH, harboring both genetic and epigenetic risks. However, their downstream effects on mRNA expression maybe ethnic specific and different from NHW.

Risk factors of undiagnosed and uncontrolled hypertension in primary care patients with hypertension: a cross-sectional study.

BACKGROUND: Hypertension is a common heart condition in the United States (US) and severely impacts racial and ethnic minority populations. While the understanding of hypertension has grown considerably, there remain gaps in US healthcare research. Specifically, there is a lack of focus on undiagnosed and uncontrolled hypertension in primary care settings. AIM: The present study investigates factors associated with undiagnosed and uncontrolled hypertension in primary care patients with hypertension. The study also examines whether Black/African Americans are at higher odds of undiagnosed and uncontrolled hypertension compared to White patients. METHODS: A cross-sectional study was conducted using electronic health records (EHR) data from the University of Utah primary care health system. The study included for analysis 24,915 patients with hypertension who had a primary care visit from January 2020 to December 2020. Multivariate logistic regression assessed the odds of undiagnosed and uncontrolled hypertension. RESULTS: Among 24,915 patients with hypertension, 28.6% (n = 7,124) were undiagnosed and 37.4% (n = 9,319) were uncontrolled. Factors associated with higher odds of undiagnosed hypertension included age 18-44 (2.05 [1.90-2.21]), Hispanic/Latino ethnicity (1.13 [1.03-1.23]),  Medicaid (1.43 [1.29-1.58]) or self-pay  (1.32 [1.13-1.53]) insurance, CCI 1-2 (1.79 [1.67-1.92]), and LDL-c ≥ 190 mg/dl (3.05 [1.41-6.59]). For uncontrolled hypertension, risk factors included age 65+ (1.11 [1.08-1.34]), male (1.24 [1.17-1.31]), Native-Hawaiian/Pacific Islander (1.32 [1.05-1.62])  or Black/African American race (1.24 [1.11-1.57]) , and self-pay insurance (1.11 [1.03-1.22]). CONCLUSION: The results of this study suggest that undiagnosed and uncontrolled hypertension is prevalent in primary care. Critical risk factors for undiagnosed hypertension include younger age, Hispanic/Latino ethnicity, very high LDL-c, low comorbidity scores, and self-pay or medicaid insurance. For uncontrolled hypertension, geriatric populations, males, Native Hawaiian/Pacific Islanders, and Black/African Americans, continue to experience greater burdens than their counterparts. Substantial efforts are needed to strengthen hypertension diagnosis and to develop tailored hypertension management programs in primary care, focusing on these populations.

¿No Hay Racismo?: application of the levels of racism framework to Latinx perspectives on barriers to health and wellbeing.

BACKGROUND: The purpose of this study is to increase understanding of the forms of systemic racism experienced by Latinx communities in North Carolina during the COVID-19 pandemic as identified by Latinx community health workers (CHWs) and community-based organization (CBO) leaders. METHODS: We held three focus groups in July 2022 (N = 16) with CHWs and CBO leaders in Spanish to discuss policy and community interventions that improved access to resources during the COVID-19 pandemic; policy or community interventions needed to improve care of Latinx communities; and lessons learned to improve the health of Latinx communities in the future. We performed directed and summative qualitative content analysis of the data in the original language using the Levels of Racism Framework by Dr. Camara Jones to identify examples of implicitly and explicitly discussed forms of systemic racism. RESULTS: Latinx CHWs and CBO leaders implicitly discussed numerous examples of all levels of racism when seeking and receiving health services, such as lack of resources for undocumented individuals and negative interactions with non-Latinx individuals, but did not explicitly name racism. Themes related to institutionalized racism included: differential access to resources due to language barriers; uninsured or undocumented status; exclusionary policies not accounting for cultural or socioeconomic differences; lack of action despite need; and difficulties obtaining sustainable funding. Themes related to personally-mediated racism included: lack of cultural awareness or humility; fear-inciting misinformation targeting Latinx populations; and negative interactions with non-Latinx individuals, organizations, or institutions. Themes related to internalized racism included: fear of seeking information or medical care; resignation or hopelessness; and competition among Latinx CBOs. Similarly, CHWs and CBO leaders discussed several interventions with systems-level impact without explicitly mentioning policy or policy change. CONCLUSION: Our research demonstrates community-identified examples of racism and confirms that Latinx populations often do not name racism explicitly. Such language gaps limit the ability of CHWs and CBOs to highlight injustices and limit the ability of communities to advocate for themselves. Although generally COVID-19 focused, themes identified represent long-standing, systemic barriers affecting Latinx communities. It is therefore critical that public and private policymakers consider these language gaps and engage with Latinx communities to develop community-informed anti-racist policies to sustainably reduce forms of racism experienced by this unique population.

Ethnic differences in the patterns, sources, and reasons for cannabis use among cancer patients at an NCI-Designated Cancer Center.

OBJECTIVE: This study aims to describe patterns, sources, and reasons for cannabis use among cancer patients by ethnic group. METHODS: Data are from a cross-sectional study of 416 surveys collected via RedCap anonymously from adult cancer patients seen at a National Cancer Institute-designated comprehensive cancer center within the last 5 years. A harmonized survey was created with 11 other National Cancer Institute centers to assess cannabis use patterns, sources, and reasons for use. Sociodemographics and cancer details were also collected via self-report. Descriptive statistics by ethnic group were compared using χ2 and Fisher exact tests. RESULTS: Among the sample (age mean = 50.4 [15.7] years; 53% male; 8.3% lesbian, gay, bisexual, transgender, queer; 46.7% Hispanic and Latinx individuals), 69.6% reported lifetime use of cannabis, 33.7% began cannabis use after cancer diagnosis, 48.1% of those consuming cannabis did not have a prescription for cannabis, and 29.4% of cannabis users consumed daily. The frequency of cannabis use (P = .04) and reasons for cannabis use (P = .02) varied by ethnic group. Sleep and pain were the most prevalent reasons for use among the Hispanics and Latinx populations; pain, mental health management, and neuropathy were the most prevalent reasons for cannabis use among non-Hispanic White individuals. CONCLUSIONS: Patterns and reasons for cannabis use differed among cancer patients by ethnic group in this exploratory cross-sectional study aimed to provide data for more rigorous study. Understanding these distinctions are pivotal in conducting more rigorous studies that address the unique needs of diverse populations utilizing cannabis for managing cancer-related symptoms.

Branched-Chain and Aromatic Amino Acids, Type 2 Diabetes, and Cardiometabolic Risk Factors among Puerto Rican Adults.

(1) Background: Branched-chain and aromatic amino acids (BCAAs/AAAs) have been considered as markers of type 2 diabetes (T2D); however, studies on associations between these metabolites and T2D and cardiometabolic traits in Hispanic populations are limited. The aim of this study was to examine the associations between baseline BCAAs (isoleucine, leucine, valine)/AAAs (phenylalanine, tyrosine) and prevalent and incident T2D, as well as baseline and longitudinal (2 year) changes in cardiometabolic traits (measures of glycemia, dyslipidemia, inflammation, and obesity) in two large cohorts of adults of Puerto Rican descent. (2) Methods: We included participants of the Boston Puerto Rican Health Study (BPRHS, n = 670) and San Juan Overweight Adult Longitudinal study (SOALS, n = 999) with available baseline metabolite and covariate data. T2D diagnosis was defined based on American Diabetes Association criteria. Multivariable logistic (for baseline T2D), Poisson (for incident T2D), and linear (for cardiometabolic traits) regression models were used; cohort-specific results were combined in the meta-analysis and adjusted for multiple comparisons. (3) Results: Higher baseline BCAAs were associated with higher odds of prevalent T2D (OR1SD BCAA score = 1.46, 95% CI: 1.34-1.59, p < 0.0001) and higher risk of incident T2D (IRR1SD BCAA score = 1.24, 95% CI: 1.13-1.37, p < 0.0001). In multivariable longitudinal analysis, higher leucine and valine concentrations were associated with 2-year increase in insulin (beta 1SD leucine = 0.37 mcU/mL, 95% CI: 0.11-0.63, p < 0.05; beta 1SD valine = 0.43 mcU/mL, 95% CI: 0.17-0.68, p < 0.01). Tyrosine was a significant predictor of incident T2D (IRR = 1.31, 95% CI: 1.09-1.58, p < 0.05), as well as 2 year increases in HOMA-IR (beta 1SD tyrosine = 0.13, 95% CI: 0.04-0.22, p < 0.05) and insulin concentrations (beta 1SD tyrosine = 0.37 mcU/mL, 95% CI: 0.12-0.61, p < 0.05). (4) Conclusions: Our results confirmed the associations between BCAAs and prevalent and incident T2D, as well as concurrent measures of glycemia, dyslipidemia, and obesity, previously reported in predominantly White and Asian populations. Baseline leucine, valine, and tyrosine were predictors of 2 year increases in insulin, whereas tyrosine was a significant predictor of deteriorating insulin resistance over time. Our study suggests that BCAAs and tyrosine could serve as early markers of future glycemic changes in Puerto Ricans.

Positive and Negative Gender Role Beliefs and Intimate Partner Violence.

An ethnically diverse sample of 384 male and female undergraduates was assessed for their gender role beliefs based on positive (family responsibility) vs. negative (male dominance and female submissiveness) aspects derived from Hispanic cultural traditions. Negative male and female gender role beliefs were significantly positively correlated with reported victimization by and perpetration of severe intimate partner violence (IPV) for both men and women. Positive male gender role beliefs were negatively correlated with reported victimization by and perpetration of IPV for both men and women, with women also providing some evidence that positive female gender role beliefs were associated with less IPV.

Attitudes towards depression and its treatment among white, hispanic, and multiracial adults.

BACKGROUND: Depression is present in all societies and affects members of all racial and ethnic groups. However, attitudes about depression differ across groups and have been shown to impact help-seeking behaviors, preferences for treatments, and compliance with treatments. METHODS: Taking a cross-cultural approach, this project used a case vignette of depression to examine race/ethnic group differences in attitudes about depression and its treatment among young adults in the U.S. RESULTS: Data analyses revealed significant racial/ethnic group differences in attitudes as well as the treatments/strategies participants reported they would use. Gender x race/ethnicity interactions revealed that White and Multiracial/ethnic men were more likely to believe the vignette character should find a partner to help with symptoms, while White and Multiracial/ethnic women did not endorse those strategies. Hispanic men and women did not show a gender difference in that strategy, but gender differences were observed in other strategies. In a rare comparison, majority-minority Multiracial/ethnic participants (i.e., White selected as one of their races/ethnicities) rated identified helpers and treatments similarly to White participants and significantly higher than multiple-minority Multiracial participants (i.e., White not selected as one of their races/ethnicities). CONCLUSIONS: Findings supported previous research that indicates different U.S. racial/ethnic group ideas of depression and its treatment are potentially linked with cultural values, and we suggest that investigating these more fine-grained group differences can help to inform treating professionals as well as public health messages.

Evaluating human papillomavirus (HPV) self-sampling among Latinas in the United States: A systematic review.

BACKGROUND: Latinas experience the greatest cervical cancer incidence compared with other ethnic/racial groups in the United States (US) due in part to significant disparities in screening uptake. Social and structural conditions that impede access to and participation in screening include language barriers, concerns about documentation status, logistical issues (e.g., transportation, limited clinic hours), and cultural beliefs regarding modesty and promiscuity. To overcome these challenges, self-sampling for human papillomavirus (HPV) DNA testing has emerged as a potentially promising method for promoting cervical cancer screening among this population. Thus, this systematic review aimed to assess the acceptability of HPV self-sampling among US Latinas. METHODS: Using EBSCOhost and PubMed databases, we searched for studies published in the past two decades (2003-2023) that described participation in HPV self-sampling among Latinas. Eleven articles met inclusion criteria. RESULTS: The majority of studies were conducted in Florida, California, and Puerto Rico, were single-arm designs, and involved the use of community health workers and Spanish-language materials (e.g., brochures). Across studies, the majority of participants reported that self-sampling was acceptable with respect to ease of use, comfort (lack of pain), privacy, and convenience; however, some women were concerned about the accuracy of self-sampling or whether they had performed sample collection correctly. CONCLUSION: Given the high acceptability, self-collection of cervicovaginal samples for HPV testing may offer a feasible option for enhancing participation in cervical cancer screening in this population that encounters significant barriers to screening.

LifeCourse Socioeconomic Position and Ideal Cardiovascular Health in Hispanic/Latino Adults of the Hispanic Community Health Study/Study of Latinos.

BACKGROUND: The Hispanic/Latino population experiences socioeconomic disadvantages across the lifespan. Yet, little is known about the role of these disadvantages in cardiovascular health (CVH). We assessed the association of lifecourse socioeconomic position (SEP) with ideal CVH and change in Hispanic/Latino adults. METHODS AND RESULTS: We used longitudinal data from the HCHS/SOL (Hispanic Community Health Study/Study of Latinos). Childhood SEP was determined using parental educational attainment. Adult SEP was determined through an index combining participants' education, occupation, income, and assets at baseline. We classified participants into 4 socioeconomic mobility categories (eg, stable low or high SEP, upward or downward mobility). Using the 4 health factors of the American Heart Association "Life's Essential 8," we built a score of ideal CVH at baseline and the 6-year follow-up. Linear mixed-effects models using inverse probability weighting were fitted to assess the main associations. Higher childhood SEP was associated with higher ideal CVH at baseline (ß for high school versus high school versus

Fentanyl harm reduction strategies among Latinx communities in the United States: a scoping review.

PURPOSE: Fueled by the prescription opioid overdose crisis and increased influx of illicitly manufactured fentanyl, fentanyl overdoses continue to be a public health crisis that has cost the US economy over $1 trillion in reduced productivity, health care, family assistance, criminal justice, and accounted for over 74,000 deaths in 2023. A recent demographic shift in the opioid crisis has led to a rise in overdose deaths among the Latinx population. Harm reduction interventions, including the use of naloxone and fentanyl test strips, have been shown to be effective measures at reducing the number of opioid overdose deaths. The aim of this scoping review is to summarize naloxone and fentanyl test strip interventions and public health policies targeted to Latinx communities. METHODS: PubMed, CINHAL, Web of Science, Embase, and PsycINFO research databases using the keywords "fentanyl," "Latinx," "Harm Reduction," "Naloxone," and "Fentanyl Test Strips'' to identify studies published between January 1, 2013 and December 31, 2023. Endnote and Covidence software were used to catalog and manage citations for review of studies. Subsequently, studies that met inclusion criteria were then summarized using resulting themes. RESULTS: Twenty-seven articles met the inclusion criteria and were further abstracted for the scoping review. Of these articles, 77.7% (n = 21) included a naloxone intervention, while only 11.1% (n = 3) included a fentanyl test strip intervention. Furthermore, 30.1% (n = 8) of these studies were Latinx targeted, and 7.7% (n = 2) of the studies were adapted for Latinx populations. Four themes, including an overall lack of knowledge and awareness, a lack of access to harm reduction or opioid overdose prevention resources, an overall lack of culturally adapted and/or targeted interventions, and restrictive and punitive policies that limit the effectiveness of protective factors were highlighted in this scoping review. CONCLUSION: Limited published research exists on the use of emerging harm reduction behaviors, such as the use of naloxone and fentanyl test strips as community intervention strategies to prevent opioid overdose deaths. Even fewer publications exist on the targeting and cultural adaptation of harm reduction interventions responsive to Latinx communities, especially those using theoretical approaches or frameworks to support these interventions. Future research is needed to assess the unique needs of Latinx populations and to develop culturally responsive programs to prevent opioid-related overdose deaths among this population.

A Protocol for the Inclusion of Minoritized Persons in Alzheimer Disease Research From the ADNI3 Diversity Taskforce.

Importance: Black or African American (hereinafter, Black) and Hispanic or Latino/a/x (hereinafter, Latinx) adults are disproportionally affected by Alzheimer disease, but most research studies do not enroll adequate numbers of both of these populations. The Alzheimer's Disease Neuroimaging Initiative-3 (ADNI3) launched a diversity taskforce to pilot a multipronged effort to increase the study inclusion of Black and Latinx older adults. Objective: To describe and evaluate the culturally informed and community-engaged inclusion efforts to increase the screening and enrollment of Black and Latinx older adults in ADNI3. Design, Setting, and Participants: This cross-sectional study used baseline data from a longitudinal, multisite, observational study conducted from January 15, 2021, to July 12, 2022, with no follow-up. The study was conducted at 13 ADNI3 sites in the US. Participants included individuals aged 55 to 90 years without cognitive impairment and those with mild cognitive impairment or Alzheimer disease. Exposures: Efforts included (1) launch of an external advisory board, (2) changes to the study protocol, (3) updates to the digital prescreener, (4) selection and deployment of 13 community-engaged research study sites, (5) development and deployment of local and centralized outreach efforts, and (6) development of a community-science partnership board. Main Outcomes and Measures: Screening and enrollment numbers from centralized and local outreach efforts, digital advertisement metrics, and digital prescreener completion. Results: A total of 91 participants enrolled in the trial via centralized and local outreach efforts, of which 22 (24.2%) identified as Latinx and 55 (60.4%) identified as Black (median [IQR] age, 65.6 [IQR, 61.5-72.5] years; 62 women [68.1%]). This represented a 267.6% increase in the monthly rate of enrollment (before: 1.11 per month; during: 4.08 per month) of underrepresented populations. For the centralized effort, social media advertisements were run between June 1, 2021, and July 31, 2022, which resulted in 2079 completed digital prescreeners, of which 1289 met criteria for subsequent site-level screening. Local efforts were run between June 1, 2021, to July 31, 2022. A total of 151 participants underwent site-level screening (100 from local efforts, 41 from centralized efforts, 10 from other sources). Conclusions and Relevance: In this cross-sectional study of pilot inclusion efforts, a culturally informed, community-engaged approach increased the inclusion of Black and Latinx participants in an Alzheimer disease cohort study.
