Abstract
OBJECTIVES Experiences of vicarious racism-hearing about racism directed toward one's racial group or racist acts committed against other racial group members-and vigilance about racial discrimination have been salient during the COVID-19 pandemic. This study examined vicarious racism and vigilance in relation to symptoms of depression and anxiety among Asian and Black Americans. METHODS We used data from a cross-sectional study of 604 Asian American and 844 Black American adults aged ≥18 in the United States recruited from 5 US cities from May 21 through July 15, 2020. Multivariable linear regression models examined levels of depression and anxiety by self-reported vicarious racism and vigilance. RESULTS Controlling for sociodemographic characteristics, among both Asian and Black Americans, greater self-reported vicarious racism was associated with more symptoms of depression (Asian: β = 1.92 [95% CI, 0.97-2.87]; Black: β = 1.72 [95% CI, 0.95-2.49]) and anxiety (Asian: β = 2.40 [95% CI, 1.48-3.32]; Black: β = 1.98 [95% CI, 1.17-2.78]). Vigilance was also positively related to symptoms of depression (Asian: β = 1.54 [95% CI, 0.58-2.50]; Black: β = 0.90 [95% CI, 0.12-1.67]) and anxiety (Asian: β = 1.98 [95% CI, 1.05-2.91]; Black: β = 1.64 [95% CI, 0.82-2.45]). CONCLUSIONS Mental health problems are a pressing concern during the COVID-19 pandemic. Results from our study suggest that heightened racist sentiment, harassment, and violence against Asian and Black Americans contribute to increased risk of depression and anxiety via vicarious racism and vigilance. Public health efforts during this period should address endemic racism as well as COVID-19.

Vicarious Racism Stress and Disease Activity: the Black Women's Experiences Living with Lupus (BeWELL) Study. J Racial Ethn Health Disparities 2019; 6:1044-1051. [PMID: 31215018 DOI: 10.1007/s40615-019-00606-8] [Citation(s) in RCA: 63] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2019] [Revised: 05/30/2019] [Accepted: 06/04/2019] [Indexed: 12/13/2022]
Abstract
BACKGROUND Indirect or vicarious exposure to racism (e.g., hearing about or observing acts of racism or discrimination) is a salient source of stress for African Americans. Emerging research suggests that these "secondhand" experiences of racism may contribute to racial health inequities through stress-mediated pathways. Systemic lupus erythematosus (SLE) is an inflammatory autoimmune disease that disproportionately impacts African American women and is characterized by racial disparities in severity. Health outcomes in this population may be susceptible to vicarious racism given that SLE is shown to be sensitive to psychosocial stress. METHODS Data are from 431 African American women with SLE living in Atlanta, Georgia in the Black Women's Experiences Living with Lupus (BeWELL) Study (2015-2017). Vicarious racism stress was measured with four items assessing distress from (1) hearing about racism in the news; (2) experiences of racism among friends or family; (3) witnessing racism in public; and (4) racism depicted in movies and television shows. Multivariable linear regression was used to examine associations with disease activity measured using the Systemic Lupus Activity Questionnaire. RESULTS Adjusting for sociodemographic and health-related covariates, vicarious racism stress was associated with greater disease activity (b = 2.15; 95% CI = 1.04-3.27). This association persisted even after adjustment for personal experiences of racial discrimination (b = 1.80; 95% CI = 0.67-2.92). CONCLUSIONS Vicarious racism may result in heightened disease activity and contribute to racial disparities in SLE. Our findings suggest that acts of racism committed against members of one's racial group may have distinct health consequences beyond the immediate victim or target.

Abstract
OBJECTIVE Telomeres are protective sequences of DNA capping the ends of chromosomes that shorten over time. Leukocyte telomere length (LTL) is posited to reflect the replicative history of cells and general systemic aging of the organism. Chronic stress exposure leads to accelerated LTL shortening, which has been linked to increased susceptibility to and faster progression of aging-related diseases. This study examined longitudinal associations between LTL and experiences of racial discrimination, a qualitatively unique source of minority psychosocial stress, among African Americans. METHOD Data are from 391 African Americans in the Coronary Artery Risk Development in Young Adults (CARDIA) Telomere Ancillary Study. We examined the number of domains in which racial discrimination was experienced in relation to LTL collected in Years 15 and 25 (Y15: 2000/2001; Y25: 2010/2011). Multivariable linear regression examined if racial discrimination was associated with LTL. Latent change score analysis (LCS) examined changes in racial discrimination and LTL in relation to one another. RESULTS Controlling for racial discrimination at Y15, multivariable linear regression analyses indicated that racial discrimination at Y25 was significantly associated with LTL at Y25. This relationship remained robust after adjusting for LTL at Y15 (b = -.019, p = .015). Consistent with this finding, LCS revealed that increases in experiences of racial discrimination were associated with faster 10-year LTL shortening (b = -.019, p = .015). CONCLUSIONS This study adds to evidence that racial discrimination contributes to accelerated physiologic weathering and health declines among African Americans through its impact on biological systems, including via its effects on telomere attrition.

Abstract
Care for patients transitioning from chronic kidney disease to kidney failure often falls short of meeting patients' needs. The PREPARE NOW study is a cluster randomized controlled trial studying the effectiveness of a pragmatic health system intervention, 'Patient Centered Kidney Transition Care,' a multi-component health system intervention designed to improve patients' preparation for kidney failure treatment. Patient-Centered Kidney Transition Care provides a suite of new electronic health information tools (including a disease registry and risk prediction tools) to help providers recognize patients in need of Kidney Transitions Care and focus their attention on patients' values and treatment preferences. Patient-Centered Kidney Transition Care also adds a 'Kidney Transitions Specialist' to the nephrology health care team to facilitate patients' self-management empowerment, shared-decision making, psychosocial support, care navigation, and health care team communication. The PREPARE NOW study is conducted among eight [8] outpatient nephrology clinics at Geisinger, a large integrated health system in rural Pennsylvania. Four randomly selected nephrology clinics employ the Patient Centered Kidney Transitions Care intervention while four clinics employ usual nephrology care. To assess intervention effectiveness, patient reported, biomedical, and health system outcomes are collected annually over a period of 36 months via telephone questionnaires and electronic health records. The PREPARE NOW Study may provide needed evidence on the effectiveness of patient-centered health system interventions to improve nephrology patients' experiences, capabilities, and clinical outcomes, and it will guide the implementation of similar interventions elsewhere.

Abstract
Black women are disproportionately affected by systemic lupus erythematosus (SLE), a chronic, potentially debilitating autoimmune disease, and they also experience more rapid progression and worse outcomes compared with other groups. We examined if racial discrimination is associated with disease outcomes among 427 black women with a validated diagnosis of SLE, who live in the Atlanta, Georgia, metropolitan area, and were recruited to the Black Women's Experiences Living with Lupus Study (2015-2017). Frequency of self-reported experiences of racial discrimination in domains such as employment, housing, and medical settings was assessed using the Experiences of Discrimination measure. SLE activity in the previous 3 months, including symptoms of fatigue, fever, skin rashes, and ulcers, was measured using the Systemic Lupus Activity Questionnaire; irreversible damage to an organ or system was measured using the Brief Index of Lupus Damage. Results of multivariable linear regression analyses examining the Systemic Lupus Activity Questionnaire and log-transformed Brief Index of Lupus Damage scores indicated that increasing frequency of racial discrimination was associated with greater SLE activity (b = 2.00, 95% confidence interval: 1.32, 2.68) and organ damage (b = 0.08, 95% confidence interval: 0.02, 0.13). Comprehensive efforts to address disparities in SLE severity should include policies that address issues of racial discrimination.

Abstract
African American women with systemic lupus erythematosus (SLE) have worse disease outcomes compared to their White counterparts. Stressors associated with race may contribute to poorer health in this population through maladaptive behavioral pathways. This study investigated relationships between stress associated with anticipating racism, smoking, and SLE disease activity. Data were from 432 African American women with SLE in the Black Women's Experiences Living with Lupus (BeWELL) Study. Controlling for sociodemographic and health-related covariates, multivariable regression analyses revealed a significant association between anticipatory racism stress (ARS) and disease activity (p = 0.00, b = 1.13, 95% CI [0.43, 1.82]). A significant interaction between ARS and smoking also indicated that smoking exacerbated the effect of ARS on disease activity (p = 0.04, b = 1.95, CI = 0.04, 3.96). Test for evidence of smoking mediating the effect of ARS on disease activity were not statistically significant (z = 1.77, p = 0.08). Findings have implications for future SLE disparities research among African American women with SLE.

Abstract
Depression is a common comorbidity among Black women with systemic lupus erythematosus (SLE), an understudied autoimmune disease characterized by major racial and gender inequities. Research is needed that examines how area-level factors influence risk of depression in this population. Latent profile analysis revealed four neighborhood typologies among metropolitan Atlanta, Georgia census tracts that participants (n=438) in the Black Women's Experiences Living with Lupus (BeWELL) Study were living in: Integrated/High-SES, Moderately Segregated/Mid-SES, Highly Segregated/Mid-SES, and Highly Segregated/Low-SES. Structural equation models indicated that highly segregated census tracts were associated with the greatest levels of depression via increased subjective assessments of neighborhood disorder. Policies that invest in segregated areas and address physical and social aspects of the environment that contribute to neighborhood disorder may promote mental health among Black women with SLE.

Abstract
Disparate health consequences in African American women with systemic lupus erythematosus include greater severity of physical and psychological distress. Racism-related stress is also related to psychological distress correlates in this population. This study examined the relationships between racism-related experiences, psychological distress, and systemic lupus erythematosus activity in 430 African American women from the Black Women's Experiences Living with Lupus study. The structural equation model suggests that psychological distress mediates the relationship between racism-related stress and systemic lupus erythematosus disease activity. The impact of racism-related stress on systemic lupus erythematosus disease activity may occur primarily through their impact on psychological health variables. Implications for clinical care and future directions are explored.

Abstract
Structural racism generates racial inequities in U.S. primary education, including segregated schools, inequitable funding and resources, racial disparities in discipline and achievement, and hostile racial climates, which are risk factors for adverse youth health and development. Black youth are disproportionately exposed to adverse school contexts that may become biologically embedded via stress-mediated epigenetic pathways. This study examined whether childhood exposure to adverse school contexts is associated with changes in epigenetic aging during adolescent development. DNA methylation-based epigenetic clocks were calculated from saliva samples at ages 9 and 15 among Black (n = 774) and White (n = 287) youth in the Future of Families and Child Wellbeing Study (2009-2015). We performed latent class analyses to identify race-specific primary school contexts using administrative data on segregation, discipline, achievement, resources, economic disadvantage, and racial harassment. We then estimated change in epigenetic age acceleration from childhood to adolescence across school typologies using GrimAge, PhenoAge, and DunedinPACE epigenetic clocks. Three distinct school contexts were identified for Black youth: segregated and highly-disadvantaged (17.0%), segregated and moderately-disadvantaged (52.1%), and integrated and moderately-disadvantaged (30.8%). Two school contexts emerged for White youth: integrated and unequal (46.5%) and predominantly White & advantaged (53.5%). At age 15, Black youth who attended segregated and highly-disadvantaged primary schools experienced increases in their speed of epigenetic aging with GrimAge and DunedinPACE. Slowed epigenetic aging with GrimAge was observed for Black youth who attended integrated and moderately-disadvantaged schools. School contexts were not associated with changes in epigenetic age acceleration for White youth. Our findings suggest that manifestations of structural racism in primary school contexts are associated with early-life epigenetic age acceleration and may forecast future health inequities.

Abstract
INTRODUCTION Racial discrimination is a distinct health threat that increases disease risk among Black Americans. Psychosocial stress may compromise health through inflammatory mechanisms. This study examines incident experiences of racial discrimination and changes in the inflammatory biomarker C-reactive protein (CRP) over a two-year period among Black women with systemic lupus erythematosus (SLE)-an inflammatory autoimmune disease sensitive to psychosocial stress and characterized by stark racial inequities in outcomes. METHODS Data are from the Black Women's Experiences Living with Lupus (BeWELL) Study. Participants (n = 380) from metropolitan Atlanta, Georgia were enrolled from April 2015 to May 2017. Incident racial discrimination was assessed bi-annually via self-report using the Experiences of Discrimination measure. CRP was assessed annually over a two-year period. Latent change score analyses modeled longitudinal within-person associations between incident racial discrimination and change in log-transformed CRP from baseline to Year 2. RESULTS Incident experiences of racial discrimination were associated with elevated log-CRP across the two-year study period (b = 0.039, SE = 0.017, 95% CI: 0.006, 0.071). For each domain of incident racial discrimination experienced, CRP increased 3.98%. CONCLUSION This study contributes to growing evidence on the biological consequences of racism and is the first to document an association between incident racial discrimination and changes in inflammation among Black women with SLE. Racial inequities in SLE outcomes and other diseases driven by inflammatory pathways may be explained in part through experiences of racial discrimination.

Abstract
OBJECTIVE The skin-deep resilience hypothesis suggests that Black Americans from disadvantaged backgrounds who attain academic or professional success despite social obstacles may paradoxically experience adverse physical health outcomes. This study examined skin-deep resilience among a sample of Black women with systemic lupus erythematosus (SLE), a disease sensitive to psychosocial stress. METHOD Data were from 426 Black women with SLE from metropolitan Atlanta, Georgia, United States, recruited to the Black Women's Experiences Living with Lupus (BeWELL) Study. Multivariable linear regression models examined cross-sectional associations between adverse childhood experiences (ACEs) and SLE disease activity, and whether educational attainment and racial discrimination moderated this relationship. RESULTS There was a significant three-way interaction between educational attainment, ACEs, and racial discrimination, F(26, 399) = 2.92, p = .02. Racial discrimination was positively associated with disease activity; however, the relationship between discrimination and disease activity was the strongest among those who displayed high "resilience," indicated by those attaining a graduate degree despite experiencing high childhood adversity (≥ 3 ACEs). There was no interaction between educational attainment and discrimination among those who experienced low childhood adversity (< 3 ACEs). CONCLUSION Findings indicate that among Black women living with SLE, resilience to childhood adversity conferred worse physical health resulting from greater exposure to racial discrimination. Although educational attainment is traditionally conceptualized as protective for health, it may come with unintended physiological tolls for high-achieving Black women with SLE from disadvantaged backgrounds. Interventions aimed at "building resilience" without addressing underlying structural and social inequities could exacerbate racial health inequities.

Abstract
Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease marked by inflammation that disproportionately impacts Black women. Telomeres are repetitive sequences of DNA capping the ends of chromosomes that shorten more rapidly in response to inflammation. Studies suggest that the telomere maintenance system may be disrupted in those with SLE, who have been shown to have shorter telomeres compared to healthy controls. Among those with SLE, Blacks have been found to experience more accelerated telomere shortening compared to those of other race groups. We examined the relationship between telomere length (TL) and mortality using data from the Black Women’s Experiences Living with Lupus (BeWELL) Study. Participants were 438 Black women with a validated diagnosis of SLE living in the Atlanta, Georgia metropolitan area, recruited between April 2015 and May 2017 predominantly from a large population-based registry. TL was assayed from dried blood spots collected at baseline and measured as the relative telomere to single copy gene (T/S) ratio. Mortality was assessed prospectively through April 2019. A total of 24 participants died during this time period. There was a negative association between TL and mortality, with shorter TL being associated with greater mortality risk (hazard ratio = 0.01, p=0.02). This relationship remained statistically significant after controlling for age and years since diagnosis, and further adjustment for a range of socio-demographic and health-related factors, including SLE damage and activity. Findings suggest that TL may forecast mortality among Black women with SLE. The association between TL and mortality among people with SLE should be further explored.

Background Despite having higher exposure to stressors, many ethno-racial groups report similar or lower prevalence of clinical depression and anxiety compared to their White counterparts, despite experiencing greater psychosocial risk factors for poor mental health outcomes, thus presenting an epidemiological paradox. Ethno-racial differences in impairment, a diagnostic criterion, may in part explain this paradox. Methods We analyzed data from the Healthy Minds Study (2020-2021) and using survey-weighted linear mixed effects models, we tested whether there were ethno-racial differences in impairment across multiple ethno-racial groups at various levels of severity for anxiety and depression. Results Black students reported lower mean impairment scores relative to White students at moderate and severe anxiety. Hispanic/Latine students only reported lower impairment relative to White students at severe anxiety. Asian students reported relatively lower mean impairment than White students at mild anxiety, and this difference continued to grow as anxiety severity increased. Similar trends were observed for depression. Black and Hispanic/Latino students reported lower mean impairment scores at moderate to severe depression. Asian students reported lower mean impairment scores beginning at mild depression to severe depression. Conclusion Self-reported anxiety and depression related impairment varies by ethno-racial group, with Black, Hispanic/Latinx, and Asian students reporting lower impairment compared to White students at higher levels of symptom severity. These findings open the possibility that racial differences in the impairment criterion of clinical diagnoses may explain some of the racial paradox.

Abstract
Objective The study objective was to compare leukocyte telomere length (LTL) among patients with systemic lupus erythematosus (SLE) diagnosed in childhood versus adulthood. Methods Data are from the Black Women's Experiences Living with Lupus (BeWELL) study. Multivariable linear regression analyses that examined childhood diagnosis of SLE (diagnosed before 18 years of age), age, and their interaction in relationship to LTL were conducted, adjusting for a range of demographic, socioeconomic, and health‐related covariates. Results The total analytic sample size was 415. Forty participants (9.6%) were diagnosed in childhood. There was no main effect of childhood diagnosis on LTL (b = 0.007; 95% confidence interval [CI]: −0.089 to 0.103). However, the interaction between age and childhood diagnosis was significant (b = −0.008; 95% CI: −0.016 to −0.001), indicating a steeper inverse association between age and LTL among those diagnosed in childhood compared with those diagnosed in adulthood. This interaction remained statistically significant (P = 0.024) after controlling for disease duration measured dichotomously (less than 10 years vs. 10 years or more); it was marginally significant (P = 0.083) when controlling for disease duration measured continuously. Conclusion This cross‐sectional analysis suggests that Black women with childhood‐onset SLE may undergo accelerated LTL shortening compared with their adult‐onset counterparts. This relationship persisted even after controlling for differences in SLE damage and disease duration. These findings inform research on immunosenescence mechanisms of SLE.

Abstract
Importance Individuals exposed to discrimination may exhibit greater epigenetic age acceleration (ie, cellular indicators of premature aging) over time, but few studies have examined longitudinal changes in epigenetic age acceleration, the heterogeneity in these changes for diverse groups of youths, and contextual explanations (ie, discrimination) for differences by ethnicity or race. Objective To provide a descriptive illustration of changes in epigenetic age acceleration across childhood and adolescence among an ethnically and racially diverse sample of youths. Design, Setting, and Participants This cohort study leveraged longitudinal data on a large sample of youths from low-income households in 20 large urban US cities who provided repeated assessments of saliva tissue samples at ages 9 and 15 years for DNA methylation analysis. Of 4898 youths from the Future of Families and Child Well-Being study, an ongoing study that oversampled children born to unmarried parents from 1998 to 2000, 2039 were included in the present analysis, as these youths had salivary DNA methylation data assayed and publicly available. Analyses were conducted from March 2023 to June 2024. Exposures Racialized intrusive encounters with police (eg, stop and frisk and racial slurs). Main Outcomes and Measures Analyses were conducted to examine longitudinal changes in salivary epigenetic age acceleration over time, whether such changes varied across ethnically and racially diverse groups of youths, and whether police intrusion was associated with variation across ethnic and racial groups. Results Among 2039 youths (mean [SD] age at baseline, 9.27 [0.38] years; 1023 [50%] male and 1016 [50%] female; 917 [45%] Black, 430 [21%] Hispanic or Latino, 351 [17%] White, and 341 [17%] other, including multiple races and self-identified other) with salivary epigenetic clocks at 9 and 15 years of age, longitudinal results showed that White youths exhibited less accelerated epigenetic aging over time than did Black and Hispanic or Latino youths and those reporting other or multiple races or ethnicities from ages 9 to 15 years, particularly in the Hannum (B, 1.54; 95% CI, 0.36-2.18), GrimAge (B, 1.31; 95% CI, 0.68-1.97), and DunedinPACE epigenetic clocks (B, 0.27; 95% CI, 0.11-0.44). Across these clocks and the PhenoAge clock, police intrusion was associated with Black youths' more accelerated epigenetic aging (Hannum: B, 0.11; 95% CI, 0.03-0.23; GrimAge: B, 0.09; 95% CI, 0.03-0.18; PhenoAge: B, 0.08; 95% CI, 0.02-0.18; DunedinPACE: B, 0.01; 95% CI, 0.01-0.03). Conclusions and Relevance The transition from childhood to adolescence may represent a sensitive developmental period when racism can have long-term deleterious impacts on healthy human development across the life span. Future research should build on the present study and interrogate which social regularities and policies may be perpetuating discrimination against ethnically and racially minoritized adolescents.

Abstract
OBJECTIVE Black/African American women with systemic lupus erythematosus (SLE) experience greater organ damage and at younger ages than white women. The objective of this study was to advance research on SLE inequities by identifying sociodemographic risk profiles associated with organ damage accrual specifically among Black/African American women. METHODS Latent profile analysis was conducted among 438 Black/African American women with SLE living in Atlanta, GA and enrolled in the Black Women's Experiences Living with Lupus (BeWELL) Study (May 2015 to April 2017). Proportional hazard and Poisson regression models examined prospective associations between sociodemographic profiles and the timing and degree of organ damage accrual over 2 years. RESULTS Four profiles emerged: (1) "Younger/Lower SES with Uncontrolled SLE" (44.8%), (2) "Older/Lower SES with Uncontrolled SLE" (23.3%), (3) "Mid-SES with Controlled SLE" (19.6%), and (4) "Higher SES with Controlled SLE" (11.2%). Approximately 42% of participants experienced new organ damage during the follow-up period. Proportional hazard models indicated that "Older/Lower SES with Uncontrolled SLE" participants were at greatest risk of new organ damage (HR = 2.41; 95% CI = 1.39, 4.19), followed by "Younger/Lower SES with Uncontrolled SLE" participants (HR = 1.56; 95% CI = 0.92, 2.67), compared to those in the "Higher SES with Controlled SLE" profile. Poisson regression models revealed that these two groups also exhibited greater organ damage accrual (b = 0.98, SE = 0.24, 95% CI = 0.52, 1.44 and b = 0.72, SE = 0.23, 95% CI = 0.27, 1.17, respectively). CONCLUSIONS Black/African American women with fewer socioeconomic resources and uncontrolled SLE are at greatest risk for increasing disease severity over time. Social inequities likely contribute to racial inequities in SLE progression.

Abstract
Abstract
Black Americans have experienced multiple health threats during the COVID-19 pandemic, including greater risk of infection compared to Whites. In addition, older adults are more susceptible to worse disease consequences including hospitalization and mortality compared to those who are younger. Racism and economic costs are additional public health crises during this time that have disproportionately impacted Black Americans. Using data from the Uncovering COVID-19 Experiences and Realities (UnCOVER) Study, we examined depressive symptoms in relation to: (1) worry/fear of COVID-19; (2) work loss among household members (being laid off, reduced work hours); and (3) vicarious racism, a particularly salient source of psychosocial stress during the COVID-19 pandemic, including hearing about or seeing acts of racism committed against other race group members. Participants were Black Americans aged 50 years or older (n=300) from five cities (Atlanta, Chicago, Los Angeles, New Orleans, and New York) from May-July 2020. Depression was assessed using the Patient-Reported Outcomes Measurement Information System Short Form. In multivariable linear regression models, all three public health threats were significantly associated with depressive symptoms. When in the model simultaneously, worry/fear of COVID-19 (b=0.30, SE=0.12, p<0.01) and vicarious racism (b=0.62, SE=0.15, p<0.001) showed positive associations; work loss was no longer statistically significant (b=0.62, SE=0.43, p=0.15). When added, the corresponding three-way interaction term was significant (b=0.12, SE=0.04, p<0.01). Synergistic epidemics (“syndemics”) among older Black Americans amplify mental health tolls. Multi-pronged public health strategies are required to address depression in this population.

Abstract
BACKGROUND Studies suggest Black Americans have a lower prevalence of depression than White Americans despite greater exposure to risk factors for depression across the life course. We examined whether this paradox exists among students in higher education, and whether the paradox may be partly explained by racial differences in reports of impairment from depression, which is a required criterion for clinical diagnosis. METHODS We analyzed data from the Healthy Minds Study (2020-2021), restricting the sample to young adults (18-29) who identified as either Black or White. Using modified Poisson regression models to estimate risk ratios, we examined associations between race and depression impairment across five levels of depression severity, adjusting for age and gender. RESULTS Approximately 23% of Black students reported depression impairment, which is significantly lower than the 28% of White students who reported depression impairment. For all students, greater depression severity was associated with greater probability of impairment; however, the relationship was more modest among Black students. At severe, moderately severe, and moderate depression levels, Black students had lower risk of depression impairment compared with White students. CONCLUSION White students may be more likely than Black students to report significant impairment at high levels of depression. These findings open the possibility that racial differences in the impairment criterion of clinical diagnoses may explain some the racial depression paradox.
