Looking White But Feeling Asian: The Role of Perceived Membership Permeability and Perceived Discrimination in Multiracial-Monoracial Alliances.

Relatively little is known about the extent to which multiracial people stand in solidarity with their parent groups. Here, we draw from social identity theory to examine predictors of Asian-White multiracial people's solidarity with Asian and White people, Asian monoracial people's meta-perceptions of these solidarity levels, and consequences of these meta-perceptions for intergroup relations. Studies 1a-b show that Asian-White multiracial people stand in solidarity more strongly with Asian people than White people, especially when they perceive high levels of anti-Asian discrimination, and even when they believe they physically look White. Studies 2a-b demonstrate that Asian monoracial people incorrectly believe that physically White-looking Asian-White multiracial people stand in solidarity more strongly with White people, and these pessimistic meta-perceptions are associated with more rejection of multiracial people. Study 3 provides a causal link between meta-perceptions and rejection while providing preliminary evidence that correcting these solidarity meta-perceptions can improve intergroup attitudes.

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.

Reflexive Activation of Monoracial Categories During Multiracial Categorization.

Previous research has examined the real-time cognitive processes underlying perceivers' ability to resolve racial ambiguity into monoracial categorizations, but such processes for multiracial categorizations are less clear. Using a novel, three-choice mouse-tracking paradigm, we found that when perceivers categorized faces as multiracial their hand movements revealed an initial attraction to a monoracial category (study 1). Moreover, exposure to multiracial individuals moderated these effects. When measured (Study 2) or manipulated (Study 3), multiracial exposure reduced monoracial category activation and activation occurred for both morphed and real multiracial faces (Study 4). Together, the findings suggest that multiracial categorizations emerge from dynamic competition between relatively more accessible monoracial categories and a less-accessible multiracial category, which is attenuated through greater exposure to multiracial targets. This research is the first to chart out the real-time dynamics underlying multiracial categorizations and offers a new theoretical account of this increasingly common form of social categorization.

Neighborhood Safety and Neighborhood Police Violence Are Associated with Psychological Distress among English- and Spanish-Speaking Transgender Women of Color in New York City: Finding from the TURNNT Cohort Study.

Transgender women of color (TWOC) experience high rates of police violence and victimization compared to other sexual and gender minority groups, as well as compared to other White transgender and cisgender women. While past studies have demonstrated how frequent police harassment is associated with higher psychological distress, the effect of neighborhood safety and neighborhood police violence on TWOC's mental health is rarely studied. In this study, we examine the association between neighborhood safety and neighborhood police violence with psychological distress among TWOC. Baseline self-reported data are from the TURNNT ("Trying to Understand Relationships, Networks and Neighborhoods among Transgender Woman of Color") Cohort Study (analytic n = 303). Recruitment for the study began September 2020 and ended November 2022. Eligibility criteria included being a TWOC, age 18-55, English- or Spanish-speaking, and planning to reside in the New York City metropolitan area for at least 1 year. In multivariable analyses, neighborhood safety and neighborhood police violence were associated with psychological distress. For example, individuals who reported medium levels of neighborhood police violence had 1.15 [1.03, 1.28] times the odds of experiencing psychological distress compared to those who experienced low levels of neighborhood police violence. Our data suggest that neighborhood safety and neighborhood police violence were associated with increased psychological distress among TWOC. Policies and programs to address neighborhood police violence (such as body cameras and legal consequences for abusive officers) may improve mental health among TWOC.

A hypothetical intervention to reduce inequities in anxiety for Multiracial people: simulating an intervention on childhood adversity.

Multiracial people report higher mean Adverse Childhood Experiences (ACEs) scores and prevalence of anxiety than other racial groups. Studies using statistical interactions to estimate racial differences in ACEs-anxiety associations do not show stronger associations for Multiracial people. Using data from Waves 1 (1995-97) through 4 (2008-09) of the National Longitudinal Study of Adolescent to Adult Health (Add Health), we simulated a stochastic intervention over 1,000 resampled datasets to estimate the race-specific cases averted per 1,000 of anxiety if all racial groups had the same exposure distribution of ACEs as Whites. Simulated cases averted were greatest for the Multiracial group, (median = -4.17 cases per 1,000, 95% CI: -7.42, -1.86). The model also predicted smaller risk reductions for Black participants (-0.76, 95% CI: -1.53, -0.19). CIs around estimates for other racial groups included the null. An intervention to reduce racial disparities in exposure to ACEs could help reduce the inequitable burden of anxiety on the Multiracial population. Stochastic methods support consequentialist approaches to racial health equity, and can encourage greater dialogue between public health researchers, policymakers, and practitioners.

Making sense of conflicting messages of multiracial identity: a systematic review.

Background: Ethnic-racial identity (ERI) development refers to how individuals' experiences, beliefs, and attitudes influence understanding of ethnic-racial group membership. Messages about race, from multiple ecosystems, influence identity development and how individuals come to form their ERI. There has been a shift in ERI research to focus on Multiracial populations, however, most of the research focus is on Black/white biracial and general, non-specified Multiracial populations. The ERI development process and experience for persons of other Multiracial backgrounds (e.g., AfroLatinx or AsianBlack) is not as extensively studied. This systematic literature review aims to elucidate the existing conceptualization of Multiracial ERI development for non-Black/white biracial and general Multiracial populations in the United States. Methods: A comprehensive search strategy was employed across multiple academic databases to identify relevant studies based on explicit inclusion criteria. The initial search resulted in 1,846 articles, but when only Black/white biracial and non-specified general Multiracial studies were eliminated from this review, only 18 articles met the criteria for inclusion. Results: Common themes emerged from the reviewed literature, including the importance of spaces, conflicting social messages directed at Multiracial individuals, and coping responses used by Multiracial individuals when faced with challenges by family members and peers regarding their multiracial identity. Discussion: The findings underscore the need for a more nuanced exploration of ERI development among diverse Multiracial populations. Understanding the unique strengths, experiences, and challenges of different Multiracial populations beyond the Black-white biracial paradigm is essential for understanding ERI development across and between different Multiracial populations in today's world.

Multiracial Reading the Mind in the Eyes Test (MRMET): An inclusive version of an influential measure.

Can an inclusive test of face cognition meet or exceed the psychometric properties of a prominent less inclusive test? Here, we norm and validate an updated version of the influential Reading the Mind in the Eyes Test (RMET), a clinically significant neuropsychiatric paradigm that has long been used to assess theory of mind and social cognition. Unlike the RMET, our Multiracial Reading the Mind in the Eyes Test (MRMET) incorporates racially inclusive stimuli, nongendered answer choices, ground-truth referenced answers, and more accessible vocabulary. We show, via a series of large datasets, that the MRMET meets or exceeds RMET across major psychometric indices. Moreover, the reliable signal captured by the two tests is statistically indistinguishable, evidence for full interchangeability. We thus present the MRMET as a high-quality, inclusive, normed and validated alternative to the RMET, and as a case in point that inclusivity in psychometric tests of face cognition is an achievable aim. The MRMET test and our normative and validation data sets are openly available under a CC-BY-SA 4.0 license at osf.io/ahq6n.

A study of hospitalized COVID-19 patients with AKI in a setting of multiracial developing country.

BACKGROUND: The commonest indication for hospitalization in COVID-19 patients is hypoxemia or severe respiratory symptoms. However, COVID-19 disease may result in extrapulmonary complications including kidney-related pathology. The reported incidence of renal involvement related to COVID infection varies based on geographical location. OBJECTIVE: This study aimed to assess the incidence rate of AKI in hospitalized COVID-19 patients and identify risk factors and prognostic predictors. METHOD: In this retrospective study, we recruited hospitalized COVID-19 patients from January 2021 until June 2021 at the University Malaya Medical Center. The inclusion criteria were hospitalized for ≥ 48 h with confirmed COVID-19 infection and at least 18 years old. Patient demographic and clinical data were collected from electronic medical records. The staging of AKI was based on criteria as per KDIGO guidelines. RESULTS: One thousand five hundred twenty-nine COVID patients fulfilled the inclusion criteria with a male-to-female ratio of 759 (49.6%) to 770 (50.3%). The median age was 55 (IQR: 36-66). 500 patients (32.7%) had diabetes, 621 (40.6%) had hypertension, and 5.6% (n = 85) had pre-existing chronic kidney disease (CKD). The incidence rate of AKI was 21.1% (n = 323). The percentage of COVID patients in different AKI stages of 1,2 and 3 were 16.3%, 2.1%, and 2.7%, respectively. Fifteen hospitalized patients (0.98%) required renal replacement therapy. 58.8% (n = 190) of AKI group had complete recovery of kidney function. Demographic factors included age (p < 0.001), diabetes (p < 0.001), hypertension (p < 0.012), CKD (p < 0.001), and vaccination status (p = 0.042) were associated with an increased risk of developing AKI. We found that the AKI cohort had statistically significant lower platelet counts and higher ferritin levels than the non-AKI cohort. AKI is a risk predictor of prolonged hospitalization (p < 0.001) and higher mortality rates (P < 0.001). CONCLUSION: AKI is a common clinical complication among hospitalized COVID-19 patients. The etiology of AKI is multifactorial and may have an adverse impact on patient morbidity and mortality.

The SocialVidStim: a video database of positive and negative social evaluation stimuli for use in social cognitive neuroscience paradigms.

This paper describes the SocialVidStim-a database of video stimuli available to the scientific community depicting positive and negative social evaluative and neutral statements. The SocialVidStim comprises 53 diverse individuals reflecting the demographic makeup of the USA, ranging from 9 to 41 years old, saying 20-60 positive and 20-60 negative social evaluative statements (e.g. 'You are a very trustworthy/annoying person'), and 20-60 neutral statements (e.g. 'The sky is blue'), totaling 5793 videos post-production. The SocialVidStim are designed for use in behavioral and functional magetic resonance imaging paradigms, across developmental stages, in diverse populations. This study describes stimuli development and reports initial validity and reliability data on a subset videos (N = 1890) depicting individuals aged 18-41 years. Raters perceive videos as expected: positive videos elicit positively valenced ratings, negative videos elicit negatively valenced ratings and neutral videos are rated as neutral. Test-retest reliability data demonstrate intraclass correlations in the good-to-excellent range for negative and positive videos and the moderate range for neutral videos. We also report small effects on valence and arousal that should be considered during stimuli selection, including match between rater and actor sex and actor believability. The SocialVidStim is a resource for researchers and we offer suggestions for using the SocialVidStim in future research.

Cardiometabolic Improvements After Metabolic Surgery and Related Presurgery Factors.

Context: Metabolic surgery remains the most effective and durable treatment for severe obesity and related metabolic diseases. Objective: We examined cardiometabolic improvements after metabolic surgery and associated presurgery demographic and clinical factors in a large multiracial cohort. Methods: Included were 7804 patients (20-79 years) undergoing first-time metabolic surgery at Vanderbilt University Medical Center from 1999 to 2022. Pre- and 1-year postsurgery cardiometabolic profiles were extracted from medical records, including body mass index (BMI), blood pressure, blood lipids, glucose, and hemoglobin A1c. The 10-year atherosclerotic cardiovascular disease (ASCVD) risk was estimated per American College of Cardiology/American Heart Association equations. Pre- to postsurgery cardiometabolic profiles were compared by paired t-test, and associated factors were identified by multivariable linear and logistic regression. Results: Among 7804 patients, most were women and White, while 1618 were men and 1271 were Black; median age and BMI were 45 years [interquartile range (IQR): 37-53] and 46.4 kg/m2 (IQR: 42.1-52.4). At 1-year postsurgery, patients showed significant decreases in systolic blood pressure (10.5 [95% confidence interval: 10.1, 10.9] mmHg), total cholesterol (13.5 [10.3, 16.7] mg/dL), glucose (13.6 [12.9, 14.4] mg/dL), hemoglobin A1c (1.13% [1.06, 1.20]), and 10-year ASCVD risk (absolute reduction: 1.58% [1.22, 1.94]; relative reduction: 34.4% [29.4, 39.3]); all P < .0001. Older, male, or Black patients showed less reduction in 10-year ASCVD risk and lower odds of diabetes/hypertension/dyslipidemia remission than younger, female, or White patients. Patients with a history of diabetes, hypertension, dyslipidemia, or cardiovascular disease showed less cardiometabolic improvements than those without. Results were similar with or without further adjusting for weight loss and largely sustained at 2-year postsurgery. Conclusion: Metabolic surgery results in significant cardiometabolic improvements, particularly among younger, female, or White patients and those without comorbidities.

Asking MultiCrit Questions: A Reflexive and Critical Framework to Promote Health Data Equity for the Multiracial Population.

Policy Points Health equity work primarily centers monoracial populations; however, the rapid growth of the Multiracial population and increasingly clear health disparities affecting the people in that population complicate our understanding of racial health equity. Limited resources exist for health researchers and professionals grappling with this complexity, likely contributing to the relative dearth of health literature describing the Multiracial population. We introduce a question-based framework built on core principles from Critical Multiracial Theory (MultiCrit) and Critical Race Public Health Praxis, designed for researchers, clinicians, and policymakers to encourage health data equity for the Multiracial population.

The independent and joint effect of socioeconomic status and Multiracial status on the prevalence and frequency of substance use and depression among U.S. adolescents.

AIM: While the United States is becoming increasingly Multiracial, much is still unknown about the behavioral health of these growing new generations of Multiracial Americans. To narrow this research gap, this study investigated the prevalence/frequency of substance use and major depressive episodes [MDE] among non-Hispanic Multiracial [NHM] adolescents compared to their non-Hispanic White [NHW] counterparts and whether racial differences vary by socioeconomic status. METHODS: We analyzed data from the 2015-2019 National Survey on Drug Use and Health (N = 3,645 NHM and 34,776 NHW adolescents aged 12-17). Average Marginal Effects derived from logistic regression and negative binomial regression were used to examine (1) differences in six outcomes (past-month use of alcohol, cannabis, or drugs other than cannabis [DOTC], past-year MDE, and the frequency of alcohol and cannabis use among past-month users) by Multiracial status; (2) the moderation effect of family income on these associations. RESULTS: Compared to high-income NHW adolescents, high-income NHM adolescents reported significantly higher prevalence of past-month cannabis and DOTC use, and past-year MDE. No racial differences were observed at other income levels. Furthermore, moderation analyses indicated that the effect of Multiracial status on MDE was larger in the highest income group compared to the lowest income group. CONCLUSION: Our findings suggested that NHM adolescents, particularly those from high income families, exhibit increased prevalence of drug use and depression than NHW adolescents. As the US becomes more diverse, there is a need to further examine the social and structural factors driving the identified racial differences.

Alcohol use in multiracial American youth compared with monoracial youth: A meta-analysis.

BACKGROUND AND AIMS: Although multiracial people comprise the fastest growing population in the United States, multiracial youth are nearly invisible in alcohol research. This meta-analysis synthesized the youth alcohol literature to estimate the magnitude of difference in alcohol use as a function of multiracial status. DESIGN AND MEASUREMENTS: Empirical studies reporting multiracial and monoracial comparisons in youth (aged 10-24 years) alcohol use were identified through a systematic literature search. A random-effects meta-analysis was conducted using 85 effect sizes extracted from 16 studies assessing life-time, past-year, past-month and binge alcohol use. SETTING AND PARTICIPANTS: A total of n=1 555 635 youth were assessed in the United States. FINDINGS: Multiracial youth are suggested to be more likely to endorse life-time alcohol use than Asian youth [number of studies (k) = 3; odds ratio (OR) = 1.81, 95% confidence interval (CI) = 1.01, 3.24; p = 0.04], with significant between-study heterogeneity (Q = 8.42; p < 0.001; I2  = 76%) in effect size comparisons. Multiracial youth are suggested to be more likely to endorse past-month alcohol use than Black (k = 6; OR = 1.54, 95% CI = 1.38, 1.71; p < 0.001) and Asian (k = 4; OR = 2.09, 95% CI = 1.52, 2.88; p < 0.001) youth, but less likely than White (k = 6; OR = 0.87, 95% CI = 0.84, 0.91; p < 0.001) youth, with significant between-study heterogeneity for Black youth (Q = 11.94; p = 0.03; I2  = 58%) in effect size comparisons. Lastly, multiracial youth are suggested to be more likely to endorse binge alcohol use than Black (k = 4; OR = 1.98, 95% CI = 1.62, 2.44; p < 0.001) and Asian (k = 4; OR = 2.82, 95% CI = 2.28, 3.48; p < 0.001) youth, but less likely than White (k = 5; OR = 0.75, 95% CI = 0.70, 0.81; p < 0.001) and American Indian/Alaska Native (k = 3; OR = 0.78, 95% CI = 0.71, 0.85; p < 0.001) youth, with significant between-study heterogeneity among Black (Q = 23.99; p < 0.001; I2  = 87%) and Asian (Q = 17.76; p < 0.001; I2  = 83%) youth in effect size comparisons. CONCLUSIONS: In the United States, multiracial youth report distinct alcohol use patterns compared with monoracial youth and may be at elevated alcohol use risk compared with Black and Asian youth.

Mental health outcomes of multiracial individuals: A systematic review between the years 2016 and 2022.

BACKGROUND: Emerging evidence suggests that multiracial individuals are at high risk for mental health problems. Systematic and ongoing synthesis of literature is necessary to understand mental health among multiracial individuals. METHODS: We conducted a systematic review of scholarly articles published during the years 2016-2022. Studies must have focused explicitly on mental health outcomes of biracial/multiracial individuals using quantitative methods. A total of 22 articles met criteria for this review. RESULTS: Studies were mainly from the United States, with one study from the United Kingdom and one from the Netherlands. Sample sizes ranged from 57 to 393,681. Findings revealed a complicated picture between multiracial identity and mental health, which may be a function of how multiracial identity is defined and empirically examined. Among studies comparing multiracial individuals with monoracial groups, multiracial individuals tended to have worse mental health, with notable exceptions depending on the multiracial subgroup, the mental health outcome, and the reference group. Among studies that only examined multiracial individuals, discrimination and ethno-racial identity emerged as complex explanatory factors that can shape mental health, though each of these constructs can be explored more deeply across social milieu. LIMITATIONS: The review focused on studies explicitly examining multiracial mental health, published during a limited time frame. CONCLUSION: Multiracial individuals tended to have worse mental health outcomes compared to their monoracial counterparts, with variations depending on the outcomes, populations/subgroups, contexts, and reference groups. Racial discrimination and ethno-racial identity may shape mental health trajectories of multiracial people, calling for more research to inform targeted interventions.

"That's what we think of as activism": Solidarity through care in queer Desi diaspora.

This article examines a framing of solidarity as both activism and community care work in diasporic South Asian (sometimes referred to as "Desi") communities in the US and the UK. From the vantage point of the researcher as a pansexual Indian-American activist herself, this article draws conclusions based on ethnographic research and interviews conducted with lesbian, gay, queer, and trans activists during the height of the COVID-19 pandemic and Black-led uprisings against police and state violence in the US and the UK. These conversations and this article particularly examine the participation of Desi activists and their peers in these movements, and their explorations of different modes of solidarity, from joint struggle to allyship to coconspiratorship and community transformation. They ultimately argue that queerness in Desi diaspora fosters solidarity through care that nurtures relationships across and between the diverse groups that make up LGBTQ + communities and the Desi diaspora, as well as between Desi, Black, and other racialized and diasporic communities. By examining lesbian, gay, trans, and broadly queer South Asian activists' relationships to each other and to other racialized groups in struggle, this article conceptualizes a framing of solidarity and Black and Brown liberation together that transcends difference, transphobia and TERFism, and anti-Blackness through centering kinship and care. Through the intimacies borne out of months and years on the frontlines of struggle together, this article argues that deepening an understanding of activism, kinship, and care together in Desi diasporic organizing is key to building a solidarity that imagines and moves toward new and liberated worlds.

Video telehealth emotional awareness and expression therapy for older U.S. military veterans with chronic pain: A pilot study.

OBJECTIVES: Emotional Awareness and Expression Therapy (EAET) targets trauma and emotional conflict to reduce or eliminate chronic pain, but video telehealth administration is untested. This uncontrolled pilot assessed acceptability, feasibility, and preliminary efficacy of group-based video telehealth EAET (vEAET) for older veterans with chronic musculoskeletal pain. METHODS: Twenty veterans were screened, and 16 initiated vEAET, delivered as one 60-minute individual session and eight 90-minute group sessions. Veterans completed posttreatment satisfaction ratings and pain severity (primary outcome), pain interference, anxiety, depression, functioning, social connectedness, shame, and anger questionnaires at baseline, posttreatment, and 2-month follow-up. RESULTS: Satisfaction was high, and veterans attended 7.4 (SD = 0.6) of 8 group sessions; none discontinued treatment. Veterans attained significant, large reductions in pain severity from baseline to posttreatment (p < .001, Hedges' g = -1.54) and follow-up (p < .001, g = -1.20); 14 of 16 achieved clinically significant (≥ 30%) pain reduction, and 3 achieved 90-100% pain reduction. Secondary outcomes demonstrated significant, medium-to-large improvements. CONCLUSIONS: In this small sample, vEAET produced better attendance, similar benefits, and fewer dropouts than in-person EAET in prior studies. Larger, controlled trials are needed. CLINICAL IMPLICATIONS: Group vEAET appears feasible and highly effective for older veterans with chronic pain.

Differential impact of the school context on ethnic and racial identity and depression for monoracial and multiracial early adolescents.

Introduction: This study examined the direct and indirect effects of school context (negative peer relationships, school environment) on ethnic and racial identity (ERI) development in middle school and later depression symptoms in high school. Differences by racial group were examined for non-Hispanic White (NHW) early adolescents, monoracial adolescents, and multiracial adolescents. Methods: This study used existing data from a large, multiwave, longitudinal study that included 593 racial/ethnically diverse adolescents from sixth grade through ninth grade across three public middle schools in the Pacific Northwest. Results: Using multigroup path analysis in structural equation modeling, the findings indicated differences by racial group-school environment was associated with positive ERI development in middle school for NHW and monoracial adolescents but not for multiracial adolescents. For multiracial adolescents, ERI predicted later depression symptoms. Discussion: These findings demonstrated the importance of examining school context and peer relationships in relation to ERI development and psychological wellbeing.

Assessing the Prevalence Rates of Internalizing Symptomatology Among Multiracial Adolescents in the United States: A Systematic Review.

This systematic review aimed to investigate the prevalence of internalizing symptomatology among Multiracial adolescents in the United States and to report on the methods utilized to measure Multiracial race and internalizing symptoms. A comprehensive search was conducted in Ovid MEDLINE, Embase, APA PsycInfo, and Web of Science Core Collection. The search was confined to peer-reviewed studies reporting the prevalence of any internalizing symptom among Multiracial adolescents between 10 and 24 years in the United States. Study selection, data abstraction, and quality assessments were managed by four team members. Between 2000 and 2023, nine studies provided prevalence estimates and used various methods to measure Multiracial race and internalizing symptoms. Prevalence estimates displayed considerable variability depending on symptom examined and measurement method utilized. For all internalizing symptomatology, estimates ranged between 7.5 and 55.2%; for depressive symptomatology, estimates ranged between 12.8 and 51.0%. No information on the prevalence of anxiety symptoms alone were provided. This review represents a pioneering attempt to report the prevalence of internalizing symptomatology among Multiracial adolescents in the United States, revealing significant gaps in current knowledge and methodological inconsistencies in the field. There exists a need for more comprehensive epidemiological research with this growing population.

Metabolite Signature of Life's Essential 8 and Risk of Coronary Heart Disease Among Low-Income Black and White Americans.

BACKGROUND: Life's essential 8 (LE8) is a comprehensive construct of cardiovascular health. Yet, little is known about the LE8 score, its metabolic correlates, and their predictive implications among Black Americans and low-income individuals. METHODS: In a nested case-control study of coronary heart disease (CHD) among 299 pairs of Black and 298 pairs of White low-income Americans from the Southern Community Cohort Study, we estimated LE8 score and applied untargeted plasma metabolomics and elastic net with leave-one-out cross-validation to identify metabolite signature (MetaSig) of LE8. Associations of LE8 score and MetaSig with incident CHD were examined using conditional logistic regression. The mediation effect of MetaSig on the LE8-CHD association was also examined. The external validity of MetaSig was evaluated in another nested CHD case-control study among 299 pairs of Chinese adults. RESULTS: Higher LE8 score was associated with lower CHD risk (standardized odds ratio, 0.61 [95% CI, 0.53-0.69]). The MetaSig, consisting of 133 metabolites, showed significant correlation with LE8 score (r=0.61) and inverse association with CHD (odds ratio, 0.57 [0.49-0.65]), robust to adjustment for LE8 score and across participants with different sociodemographic and health status ([odds ratios, 0.42-0.69]; all P<0.05). MetaSig mediated a large portion of the LE8-CHD association: 53% (32%-80%). Significant associations of MetaSig with LE8 score and CHD risk were found in validation cohort (r=0.49; odds ratio, 0.57 [0.46-0.69]). CONCLUSIONS: Higher LE8 score and its MetaSig were associated with lower CHD risk among low-income Black and White Americans. Metabolomics may offer an objective measure of LE8 and its metabolic phenotype relevant to CHD prevention among diverse populations.
