Perceived Discrimination and Adolescent Sleep in a Community Sample

Corresponding Changes in Sleep and Discrimination: A Three-year Longitudinal Study Among Ethnically/Racially Diverse Adolescents

Although research has established the immediate, detrimental impact of discrimination on sleep, how changes in experiences of discrimination may be related to changes in sleep duration over multiple years is less clear. This three-year longitudinal study investigated: (1) intercept-only and linear trajectories of sleep and everyday discrimination across three years of high school; (2) ethnic/racial differences in these trajectories; and (3) the associations between changes in sleep and changes in everyday discrimination. The sample consisted of ethnically/racially minoritized adolescents from five northeast U.S. public high schools (n = 329; 70% female, 30% male, 0% non-binary; 42% Asian, 21% Black, 37% Latiné; Mage = 14.72, SD = 0.54). Latent growth curve models found that both sleep duration and everyday discrimination declined linearly throughout the first three years of high school and varied by race/ethnicity. Asian adolescents reported longer sleep duration in the 9th grade relative to Black and Latiné adolescents but underwent a significant decline such that these differences were no longer significant in the 10th and 11th grades. In addition, Black and Latiné, but not Asian, adolescents reported a significant decline in discrimination from the 9th-11th grades. Although average sleep duration declined for the entire sample, slower declines in discrimination were associated with faster decreases in sleep duration. This was particularly salient among Black adolescents. The current study contributes to research on ethnic/racial disparities in sleep by highlighting that everyday discrimination can have both an immediate and cumulative detrimental impact on sleep duration.

Race, Ethnicity, and Sleep in US Children

Importance

Although racial and ethnic disparities are well documented in children's mean levels of sleep, particularly duration, evidence is mixed for sleep variability, an important sleep dimension of growing interest. Most research has also focused on comparisons of Black and White children, with limited attention to sleep variability disparities among other racially and ethnically minoritized groups such as Asian, Latinx, and multiracial children.

Objective

To investigate racial and ethnic disparities in children's mean levels of sleep and variability of sleep across multiple dimensions and diverse racial and ethnic groups using actigraphy data.

Design, Setting, and Participants

This cross-sectional study used data from the Adolescent Brain Cognitive Development (ABCD) study, a national cohort study, from 21 study sites across the US. ABCD participants were recruited at baseline (2016-2018) using a multistage, stratified, probability sampling method. The current study used a subsample with reliable actigraphy data collected at 2-year follow-up (2018-2020). Data analysis occurred from July 2023 to October 2024.

Exposures

Parent-reported race and ethnicity at baseline. Sociodemographic, health, and contextual covariates of sleep were also included.

Main Outcomes and Measures

Actigraphy-assessed mean levels of sleep and sleep variability across multiple dimensions (duration, bedtime, risetime, efficiency, and latency) over 3 weeks.

Results

The analytic sample included 3868 children (mean [SD] age, 11.50 [0.67] years; 1913 female [49.5%]), of whom 104 (2.7%) were Asian, 347 (9.0%) were Black or African American, 801 (20.7%) were Latinx, 356 (9.2%) were multiracial, and 2260 (58.4%) were White. Asian, Black, Latinx, and multiracial children exhibited shorter sleep duration and later bedtime than White children. Importantly, compared with White children, bedtime variability was greater among Asian (β = 0.04; 95% CI, 0.01 to 0.07; P = .02), Black (β = 0.11 95% CI, 0.08 to 0.15; P < .001), Latinx (β = 0.08; 95% CI, 0.05 to 0.12; P < .001), and multiracial children (β = 0.08; 95% CI, 0.05 to 0.11; P < .001). Similarly, risetime variability was greater among Asian (β = 0.04; 95% CI, 0.01 to 0.07; P = .01), Black (β = 0.08; 95% CI, 0.04 to 0.12; P < .001), and Latinx (β = 0.06; 95% CI, 0.02 to 0.10; P < .01) children in comparison with White children. Black children exhibited the most profound disparities across mean levels (duration and bedtime) and variability of sleep (duration, bedtime, risetime, and efficiency) than other groups. Asian and multiracial children also exhibited some disparities sleep duration, efficiency, and efficiency variability, when compared with Latinx children.

Conclusions and Relevance

In this cross-sectional study of children's sleep disparities, racially and ethnically minoritized children exhibited disparities in mean levels and variability of sleep compared with their White peers. These findings suggest that policies and practices should target multiple sleep dimensions among diverse racial and ethnic groups to promote equitable pediatric sleep health.

The Role of Sleep in Links Between Daily Interpersonal Stress and Internalizing and Externalizing Symptoms During Middle Childhood

Background

Interpersonal stress has been consistently linked with poorer adjustment, and healthy sleep may play a promotive or protective role in this relation. However, little is known regarding such associations among children. The current study examined longitudinal associations between daily interpersonal stress, sleep, and internalizing/externalizing symptoms during middle childhood.

Methods

At age 8 years, participants wore actigraphy watches for 7 days to capture sleep, and primary caregivers reported on children's daily interpersonal stress, internalizing/externalizing symptoms, and sleep problems. At age 9 years, children self-reported symptoms.

Results

Greater daily interpersonal stress at age 8 years predicted greater internalizing/externalizing symptoms at age 9 years. Higher sleep efficiency predicted fewer externalizing symptoms. Sleep duration moderated links between interpersonal stress and internalizing/externalizing symptoms, but associations were positive and significant for children with average and high duration only.

Conclusion

Findings advance our understanding of links between interpersonal stress, sleep, and child adjustment and can inform targeted family and school interventions.

Interplay of race and neighborhood deprivation on resting and ambulatory blood pressure in young adults

Nighttime blood pressure (BP) and BP dipping (daytime-nighttime BP) are prognostic for cardiovascular disease. When compared with other racial/ethnic groups, Black Americans exhibit elevated nighttime BP and attenuated BP dipping. Neighborhood deprivation may contribute to disparities in cardiovascular health, but its effects on resting and ambulatory BP patterns in young adults are unclear. Therefore, we examined associations between neighborhood deprivation with resting and nighttime BP and BP dipping in young Black and White adults. We recruited 19 Black and 28 White participants (23 males/24 females, 21 ± 1 yr, body mass index: 26 ± 4 kg/m2) for 24-h ambulatory BP monitoring. We assessed resting BP, nighttime BP, and BP dipping (absolute dip and nighttime:daytime BP ratio). We used the area deprivation index (ADI) to assess average neighborhood deprivation during early and mid-childhood and adolescence. When compared with White participants, Black participants exhibited higher resting systolic and diastolic BP (Ps ≤ 0.029), nighttime systolic BP (114 ± 9 vs. 108 ± 9 mmHg, P = 0.049), diastolic BP (63 ± 8 vs. 57 ± 7 mmHg, P = 0.010), and attenuated absolute systolic BP dipping (12 ± 5 vs. 9 ± 7 mmHg, P = 0.050). Black participants experienced greater average ADI scores compared with White participants [110 (10) vs. 97 (22), P = 0.002], and select ADI scores correlated with resting BP and some ambulatory BP measures. Within each race, select ADI scores correlated with some BP measures for Black participants, but there were no ADI and BP correlations for White participants. In conclusion, our findings suggest that neighborhood deprivation may contribute to higher resting BP and impaired ambulatory BP patterns in young adults warranting further investigation in larger cohorts.NEW & NOTEWORTHY We demonstrate that young Black adults exhibit higher resting blood pressure, nighttime blood pressure, and attenuated systolic blood pressure dipping compared with young White adults. Black adults were exposed to greater neighborhood deprivation, which demonstrated some associations with resting and ambulatory blood pressure. Our findings add to a growing body of literature indicating that neighborhood deprivation may contribute to increased blood pressure.

Peer-based discrimination and adolescent emotional and sleep health: A daily examination of direct and buffering associations

Using 10-day daily diary data collected in 2019 from 10th grade students in southern U.S. (N = 161, 57% Latina/x/o, 21% Biracial, 10% Asian, 9% White, 4% Black; 55% female, Mage  = 15.51), this study examined various forms of peer-based discrimination in adolescents' everyday lives. Results showed that personally experienced discrimination, peer racial teasing, and vicarious discrimination were frequent and impactful events. Results also provided strong evidence for the protective role of psychological resilience and some evidence for the protective-reactive roles of peer support and school climate in moderating the link between peer-based discrimination and daily well-being. The findings highlight the necessity to eliminate peer-based discrimination and shed light on interventions to reduce the harmful effects of peer-based discrimination on adolescents' daily well-being.

Short-term cortisol adaption to discrimination and Mexican-origin adolescents' mental and sleep health

Discrimination experiences are a salient contributor to the health disparities facing Latina/x/o youth. The biopsychosocial model of minority health posits that discrimination influences health through wear and tear on the biological stress responses, including the hypothalamic-pituitary-adrenal (HPA) axis, which is a primary stress response system in the body. Emerging evidence suggests that discrimination alters the secretion of cortisol, the end product of the HPA axis, yet, whether the daily processes between discrimination and diurnal cortisol response influence mental and sleep health remains unanswered. This study integrated daily diary and post-diary survey data to examine whether daily diurnal cortisol responses to discrimination influence adolescents' mental (depressive symptoms, anxiety) and sleep (sleep quality, duration) health in a sample of Mexican-origin youth (N = 282; M age = 17.10; 55% female). Results showed that adolescents who experienced more discrimination across the four-day diary period exhibited steeper diurnal cortisol slopes and lower evening cortisol; however, such physiological responses tended to be associated with poorer adolescents' mental and sleep health. The current study underscores the potential adaptation cost associated with short-term cortisol adaptation in the face of discrimination.

Health Disparities in Pediatric Sleep

This article reviews disparities in pediatric sleep health and sleep disorders from early childhood through adolescence (birth to age 18 years). Sleep health is a multidimensional construct including sleep duration, consolidation, and other domains, whereas sleep disorders reflect both behaviorally (eg, insomnia) and medically based (eg, sleep disordered breathing) sleep diagnoses. Using a socioecological framework, we review multilevel (ie, child, family, school, health-care system, neighborhood, and sociocultural) factors linked to sleep health disparities. Mechanistic research and studies using an intersectional lens to understand overlapping marginalized identities are needed to inform multilevel interventions to promote sleep health equity in pediatrics.

Adolescents' experiences of peer ethnic/racial victimization and school engagement in everyday life: sleep as a moderator

STUDY OBJECTIVES

Stressful ethnic/racial experiences, such as peer ethnic/racial victimization, may harm adolescents' adjustment. Using a daily diary design, the current study examined how same-night and previous-night sleep may moderate the within-person associations between peer ethnic/racial victimization and school engagement.

METHODS

The analytic sample consisted of 133 ninth graders (Mage = 14.54 years old; 44% Black, 21% White, 16% Latinx, 5% Native, 4% Asian, and 9% other). Adolescents reported their peer ethnic/racial victimization experiences and school engagement every day for 14 consecutive days. Sleep was measured objectively by actigraphy watches daily during the 14 days.

RESULTS

Multilevel analyses identified significant interactions between peer ethnic/racial victimization and same-night time in bed and latency for next-day engagement. The negative association between victimization and next-day school engagement was only significant when adolescents had shorter time in bed and longer latency than their typical levels that night, supporting the recovery role of sleep (ie, same-night sleep helps adolescents recover from victimization). There was also a significant interaction between previous-night time in bed and today's peer ethnic/racial victimization for same-day school engagement. The negative association between victimization and same-day school engagement was only significant when adolescents had shorter time in bed than their typical levels the previous night, supporting a preparatory hypothesis of sleep (ie, sleep helps prepare adolescents for next-day victimization). Neither previous-night nor same-night sleep efficiency moderated the association between victimization and school engagement.

CONCLUSIONS

Findings highlighted sleep as an important bioregulatory protective factor that may alleviate the challenges associated with ethnic/racial victimization.

Longitudinal association between perceived discrimination and sleep problems among young adults in the United States: Tests of moderation by race/ethnicity and educational attainment

RATIONALE

Although perceived discrimination is known to affect sleep, the findings of previous research are limited because they are mostly based on either cross-sectional data or non-generalizable samples, such as clinical samples. There is also little evidence on whether perceived discrimination differently affects sleep problems across different groups.

OBJECTIVE

This study examines whether perceived discrimination is related to sleep problems when considering unmeasured confounding factors and how that relationship varies by race/ethnicity and socioeconomic status from a longitudinal perspective.

METHODS

This study uses Waves 1, 4, and 5 of the National Longitudinal Study of Adolescent to Adult Health (Add Health) and conducts hybrid panel modeling to estimate both within- and between-individual effects of perceived discrimination on sleep problems.

RESULTS

First, the results of the hybrid modeling show that increased perceived discrimination in daily life is related to poorer sleep quality when accounting for unobserved heterogeneity as well as time-constant and time-varying covariates. Moreover, the moderation analyses and the subgroup analyses demonstrate that the association was not found among Hispanics and among those with a bachelor's degree or more. That is, Hispanic origin and college attainment weaken the associations between perceived discrimination and sleep problems, and the differences by race/ethnicity and socioeconomic status are statistically significant.

CONCLUSIONS

This study suggests a robust link between discrimination and sleep problems and further elaborates on whether this association varies among different groups. Efforts to reduce interpersonal and institutional discrimination (e.g., discrimination at the workplace or in the community) can help to improve sleep problems and thereby promote overall health. We also suggest that future research consider the moderating roles of susceptible and resilient factors in the relationships between discrimination and sleep.

Health disparities in pediatric sleep-disordered breathing

Sleep-disordered breathing reflects a continuum of overnight breathing difficulties, ranging from mild snoring to obstructive sleep apnea syndrome. Sleep-disordered breathing in childhood is associated with significant adverse outcomes in multiple domains of functioning. This review summarizes the evidence of well-described ethnic, racial, and socioeconomic disparities in pediatric sleep-disordered breathing, from its prevalence to its treatment-related outcomes. Research on potential socio-ecological contributors to these disparities is also reviewed. Critical future research directions include the development of interventions that address the modifiable social and environmental determinants of these health disparities.

Classmates' Discrimination Experiences and Adolescent Depressive Symptoms: Evidence From Random Assignment of Students to Classrooms in South Korea

PURPOSE

The purpose of this study is to examine the association between classmates' discrimination experiences and an individual student's depressive symptoms. A set of social-psychological and behavioral variables were considered as potential mechanisms underlying this association.

METHODS

The data came from the Gyeonggi Education Panel Study of seventh graders in South Korea. This study leveraged quasi-experimental variation generated from random assignment of students to classes within schools to address the endogenous school selection problem and account for the unobserved school-level confounders. To formally test for mediation, Sobel tests were conducted and peer attachment, school satisfaction, smoking, and drinking were explored as mechanism variables.

RESULTS

An increase in classmates' discrimination experiences was positively associated with an individual student's depressive symptoms. This association remained statistically significant even after adjusting for personal discrimination experience, a myriad of individual- and class-level covariates, as well as school fixed effects (b = 0.325, p < .05). Classmates' discrimination experiences were also associated with a decline in peer attachment and school satisfaction (b = -0.386, p < .01 and b = -0.399, p < .05, respectively). These psychosocial factors explained about one-third of the association between classmates' discrimination experiences and individual students' depressive symptoms.

DISCUSSION

The findings of this study suggest that exposure to peer-level discrimination experience leads to friend detachment and school dissatisfaction, which in turn increases an individual student's depressive symptoms. This study reaffirms the importance of fostering a more cohesive and nondiscriminatory school environment to promote adolescents' psychological health and well-being.

Discrimination and Health Among First-Generation Hispanic/Latinx Immigrants: the Roles of Sleep and Fatigue

INTRODUCTION

A growing literature documents the associations between discrimination and health. Emerging evidence suggests that among Hispanic/Latinx immigrants, discrimination leads to the deterioration of health outcomes over time. While sleep has been proposed as an important mediator of the relationship between discrimination and health, few studies have explicitly investigated this pathway, particularly among Hispanic/Latinx populations.

OBJECTIVE

To investigate the relationships between racial/ethnic discrimination, sleep, and physical and mental health among Hispanic/Latinx immigrants in the USA. Data and Methods Using data from a parent study of first-generation Hispanic/Latinx immigrants in the southeastern USA, we conducted sequential mediation analyses using the bootstrapping method to investigate whether self-reported sleep duration, sleep quality, and fatigue mediate the relationship(s) between self-reported discrimination, as measured by the discrimination subscale of the Riverside Acculturative Stress Inventory, and self-reported physical and mental health.

RESULTS

Nocturnal awakenings, fatigue, and sleep quality were statistically significant sequential mediators of the relationship between discrimination and physical health (b = -.001, SE = .001, CI [-.0027, -.0001]); fatigue alone also mediated this relationship (b = -.01, SE = .01, CI [-.0279, -.0003]). Nocturnal awakenings, fatigue, and sleep quality were also significant sequential mediators of the relationship between discrimination and mental health (b = -.001, SE = .001, CI [-.0031, -.0001]).

CONCLUSION

Sleep and fatigue play an important role in linking discrimination and health among first-generation Hispanic/Latinx immigrants. The development and implementation of interventions that focus on reducing fatigue among this population could mitigate the effects of unfair treatment on health outcomes.

Sleep and disparities in child and adolescent development

Sleep is a robust predictor of child and adolescent development. Race/ethnicity, socioeconomic status (SES), and related experiences (e.g., discrimination) are associated with sleep, but researchers have just begun to understand the role of sleep in the development of racial/ethnic and SES disparities in broader psychosocial adjustment and cognitive functioning during childhood and adolescence. In this article, we discuss poor sleep as a potential mechanism contributing to the development of such disparities, and better sleep as a potential protective factor that diminishes such disparities. We conclude by offering recommendations for research to advance understanding of sleep as a key bioregulatory system that may underlie or protect against detrimental developmental outcomes related to socioeconomic adversity and belonging to a historically minoritized group.

Linking ethnic/racial discrimination to adolescent mental health: Sleep disturbances as an explanatory pathway

Ethnic/racial discrimination is associated with negative psychosocial outcomes, and this study considered sleep disturbance as a mediating pathway. Employing a combination of daily diary and biannual surveys, multilevel structural equation models estimated the indirect effects of sleep/wake concerns on negative, anxious, and positive mood, rumination, and somatic symptoms. In a sample of 350 urban Asian (74% Chinese, 8% Korean, 4% Indian, 1% Filipinx, 1% Vietnamese, and 12% other), Black, and Latinx (25% Dominican, 24% South American, 22% Mexican, 15% Puerto Rican, 5% Central American, and 9% other) youth (M = 14.27 years, 69% female, 77% U.S. born, 76% monoethnic/racial, data collected from 2015 to 2018), there was evidence for sleep disturbances mediating the impact of ethnic/racial discrimination on adjustment. Nighttime disturbance, daytime dysfunction, and daytime sleepiness evidenced partial or full mediation for daily- and person-level outcomes (υ = 0.1%-17.9%). Reciprocal associations between sleep disturbances and negative mood and rumination were also observed.

Daily Experiences of Discrimination and Ethnic/Racial Minority Adolescents' Sleep: The Moderating Role of Social Support

Using data from a 14-day diary study of 95 ethnic/racial minority adolescents, this study examined the within-person effect of daily discrimination tied to multiple social identities on adolescents' daily sleep quality and duration and whether daily support from important others (i.e., friends, parents, and teachers) would moderate these links. We found that daily discrimination was a low-frequency, but high-impact event associated with shorter sleep duration. Results pointed to the nuanced roles of daily support. Support from friends was negatively related to sleep duration, whereas support from parents appeared to be promotive to sleep quality. Support from teachers protected adolescents from the negative effects of discrimination on sleep duration. Implications for future interventions targeting sleep disturbances associated with discrimination are discussed.

Every Day Matters: Using Daily Methods to Understand Oppression and BIPOC Youth Development in Context

There is an increasing use of daily methods (e.g., daily diaries, experience sampling method) by research investigating the roles of oppression, racism, and discrimination on Black, Indigenous and People of Color (BIPOC) youth adjustment. This commentary discusses several promising directions in which daily methods can help (1) understand adolescents' oppression-related experiences in everyday life, (2) investigate the immediate and long-term implications of these experiences, and (3) explore the role of protective processes and broader contexts. Moving forward, daily methods can be more broadly integrated into other methodologies (e.g., longitudinal designs, qualitative/mixed methods), providing unique insights into how systems of oppression become relevant in BIPOC adolescents' everyday life and informing practices to improve their adjustment on a daily basis and over the long term.

Discrimination and adjustment in adolescence: the moderating role of sleep

STUDY OBJECTIVES

We examined multiple actigraphy-based sleep parameters as moderators of associations between experiences of general and racial discrimination and adolescent internalizing symptoms (anxiety, depression) and externalizing behavior (rule-breaking). Adolescent sex and race were examined as additional moderators.

METHODS

Participants were 272 adolescents (Mage = 17.3 years, SD = 0.76; 51% male; 59% White/European American, 41% Black/African American). Sleep was assessed using actigraphs for 7 consecutive nights from which sleep duration (minutes), efficiency, and variability in minutes over the week were derived. Youth reported on their experiences of general discrimination, racial discrimination, anxiety, depressive symptoms, and rule-breaking behavior.

RESULTS

Both types of discrimination were associated with poorer adjustment outcomes. Longer sleep duration, greater sleep efficiency, and less variability in sleep duration were protective in associations between race-specific and general discrimination and internalizing symptoms. Findings for duration and efficiency were more pronounced for females such that the adverse effects of discrimination were minimized among females with longer and more efficient sleep. Greater variability in sleep exacerbated rule-breaking behavior among adolescents experiencing general or racial discrimination. Associations did not differ by adolescent race.

CONCLUSIONS

Short and poor-quality sleep may exacerbate internalizing symptoms for adolescents experiencing discrimination, particularly females. Variability in sleep duration was a key moderator of associations between discrimination and internalizing symptoms as well as rule-breaking behavior. Findings illustrate that actigraphy-assessed sleep parameters play a key role in ameliorating or exacerbating adjustment problems associated with discrimination.

The Impact of Daily Discrimination on Sleep/Wake Problem Trajectories Among Diverse Adolescents

This study examines how everyday discrimination is associated with 6-day trajectories of sleep/wake problems, operationalized as sleep disturbance and daytime dysfunction, among 350 diverse adolescents (Mage  = 14.27, SD = 0.61, 69% female; 22% African American, 41% Asian American, 37% Latinx; 24% multiethnic/racial; across participating schools, 72% of students eligible for free/reduced price lunch) in the Northeastern United States. Adolescents encountering discrimination experienced changes in sleep/wake problem trajectories (i.e., significant increases in same-day sleep/wake problems), whereas adolescents reporting no discrimination experienced no changes in trajectories (Cohen's ds = .51-.55). Multiethnic/racial (compared to monoethnic/racial) adolescents experiencing everyday discrimination reported greater same-day sleep/wake problems, yet steeper decreases in sleep/wake problems suggesting stronger impact coupled with faster return to baseline levels.

Sleep disparities during the COVID-19 pandemic: An investigation of AIAN, Asian, Black, Latinx, and White young adults

OBJECTIVES

This study investigates race-related disparities in sleep duration and quality among diverse young adults during the coronavirus 2019 (COVID-19) pandemic.

DESIGN & SETTING

Online cross-sectional study of young adults in the United States in April 2020.

PARTICIPANTS

About 547 American Indian/Alaskan Native (AIAN), Asian, Black, Latinx, and White young adults ages 18-25 years.

MEASUREMENTS

Participants completed measures of sleep duration and quality, coronavirus victimization distress, depression, age, sex/gender, employment status, essential worker status, student status, residential region, socioeconomic status, concerns about contracting coronavirus and CDC health risks.

RESULTS

Black young adults reported the largest disparity in sleep duration and quality. For sleep duration, AIAN, Asian, White, and Latinx young adults reported approximately one additional hour of sleep compared to Black respondents. Mediation analyses suggest that disparities in sleep duration between Asian and Black young adults may be explained by the higher likelihood of Black respondents being essential workers. For sleep quality, Latinx, White, AIAN, and Asian young adults reported higher levels than Black respondents. Including coronavirus victimization distress as an intervening pathway decreased the effect for Asian and White respondents on sleep quality, suggesting that coronavirus victimization distress partially explains Black and Asian, as well as Black and White differences in sleep quality.

CONCLUSIONS

Black young adults reported the shortest sleep duration and lowest levels of sleep quality relative to AIAN, Asian, Latinx and White peers. Interpersonal experiences of coronavirus victimization and structural inequities may partially explain disparities during the COVID-19 pandemic.

Got Skillz? Recasting and Negotiating Racial Tension in Teacher–Student Relationships Amidst Shifting Demographics

This paper reports on a curriculum designed for Black students whose school teachers and administrators sought to address concerns about students’ academic underachievement and behavioral challenges. In order to design the curriculum, we examined Black students’ reactions to race- and academic-related stress as a result of their interactions with mostly White teachers and peers in an increasingly diversifying predominantly White, middle-class community. Grounded in principles of Racial Encounter Coping Appraisal and Socialization Theory (RECAST), a paradigm for understanding the racial coping strategies utilized by individuals to contend with racial stress and well-being, the study sought to elucidate racial tensions found in schooling relationships that foster racial disparities in classrooms. Specifically, our team conducted focus group sessions with Black parents and students which were guided by our use of the Cultural and Racial Experiences of Socialization Survey (CARES), a racial and ethnic socialization measure that elicits responses from students about the kinds of messages students receive about race and ethnicity from people parents and teachers. Data from the sessions subsequently informed the design of Let’s Talk? (LT), a racial conflict resolution curriculum for Black adolescents. In this paper, we share what we learned about students’ school experiences and coping mechanism through their participation in LT.

Linking discrimination and sleep with biomarker profiles: An investigation in the MIDUS study

Self-reported experiences of discrimination and sleep dysfunction have both been shown to adversely impact biological functioning; however, few studies have examined how they are jointly associated with health. The current study draws from two samples of the Midlife in the United States (MIDUS) data (n = 617 participants; 59.8% female; 72.3% White and 27.7% African American; Age: Mean = 52.6, SD = 12.22) to identify profiles of sleep (duration, variability, onset latency, wake after sleep onset, naps) and discrimination (everyday, lifetime, impact). Associations with latent profiles of biomarkers of inflammation (CRP, fibrinogen, IL-6) and endocrine stress (cortisol, epinephrine, norepinephrine) were examined. Three profiles were identified for sleep/discrimination (good, fair, poor) and for biomarkers (average, high inflammation, high neuroendocrine). Chi-square analyses indicated that adults in the good sleep/low discrimination profile were more likely to be in the average biomarker profile but less likely to be in the high inflammation profile. Adults in the fair sleep/moderate discrimination risk profile were more likely to be in the high inflammation profile. Adults in the poor sleep/high discrimination risk profile were less likely to be in the average biomarker profile but more likely to be in the high inflammation profile. The current study identified configurations of sleep and discrimination among midlife adults which were associated with profiles of biological risk. The findings provide implications for identifying individuals who may be at increased risk of developing stress-related tertiary outcomes of morbidity and disease.

Racial discrimination, depressive symptoms, and sleep problems among Blacks in the rural South

OBJECTIVES

Experiences of racial discrimination are common for Black Americans and have been associated with depression and sleep disturbance, factors likely involved in the insidious development of health disparities. The current study replicates these associations and examines longitudinal linkages.

METHOD

Black American couples (men: N = 248, Mage = 40, SD = 9; women: N = 277, Mage = 37, SD = 7) and their children, aged 9 to 14 (N = 276, Mage = 11, SD = 1), completed measures of experiences of racial discrimination, depressive symptoms, and sleep problems at baseline and 8-month follow-up. In separate analyses for men, women, and youth, we examined concurrent and prospective associations of racial discrimination with depressive symptoms and sleep problems, then used longitudinal indirect effect models to examine whether depressive symptoms in response to racial discrimination led to increased sleep problems, or vice versa.

RESULTS

Racial discrimination was associated concurrently with depressive symptoms and sleep problems for all family members. Prospective associations were also found with depressive symptoms and sleep problems in fathers and youth, and sleep problems in mothers. Longitudinal models showed significant indirect effects of racial discrimination on change in sleep problems through depressive symptoms for fathers and mothers, and a similar, but nonsignificant, pattern in youth. There were no indirect effects on change in depressive symptoms through sleep problems.

CONCLUSIONS

Persistent associations of racial discrimination with depressive symptoms and sleep problems reflect a lasting impact of racial discrimination. Because discrimination's effects on depression may contribute to increased sleep problems over time, interventions that buffer the effects of discrimination on depressive symptoms may also reduce sleep problems.

Racial discrimination and socioemotional and sleep problems in a cross-sectional survey of Australian school students

OBJECTIVE

To determine the prevalence of direct and vicarious racial discrimination experiences from peer, school and societal sources, and examine associations between these experiences and socioemotional and sleep outcomes.

METHODS

Data were analysed from a population representative cross-sectional study of n=4664 school students in years 5-9 (10-15 years of age) in Australia. Students reported direct experiences of racial discrimination from peers, school and societal sources; vicarious discrimination was measured according to the frequency of witnessing other students experiences of racial discrimination. Students self-reported on the Strengths and Difficulties Questionnaire, with the total difficulties, conduct, emotional and prosocial behaviour subscales examined. Sleep problems included duration, latency, and disruption.

RESULTS

41.56% (95% CI 36.18 to 47.15) of students reported experiences of direct racial discrimination; Indigenous and ethnic minority students reported the highest levels. 70.15% (95% CI 63.83 to 75.78) of students reported vicarious racial discrimination. Direct and vicarious experiences of racial discrimination were associated with socioemotional adjustment (eg, for total difficulties, total direct racism: beta=3.77, 95% CI 3.11 to 4.44; vicarious racism: beta=2.51, 95% CI 2.00 to 3.03). Strong evidence was also found for an effect of direct and vicarious discrimination on sleep (eg, for sleep duration, total direct: beta=-21.04, 95% CI -37.67 to -4.40; vicarious: beta=-9.82, 95% CI -13.78 to -5.86).

CONCLUSIONS

Experiences of direct and vicarious racial discrimination are common for students from Indigenous and ethnic minority backgrounds, and are associated with socioemotional and sleep problems in adolescence. Racism and racial discrimination are critically important to tackle as social determinants of health for children and adolescents.

Sleep, psychopathology and cultural diversity

Research on ethnic/racial disparities in sleep in the United States finds minorities to have shorter self-reported and actigraphy-recorded sleep duration and poorer sleep quality. Disparities in mental health mirror disparities in sleep with ethnic/racial minorities reporting higher prevalence and more severe struggles. This review focuses on recent research in sleep and mental health disparities and considers ethnic/racial discrimination as an important third variable that may link these two domains of disparities research. For example, research has found discrimination to mediate ethnic/racial disparities in sleep; at the same time, sleep has been observed to mediate the link between discrimination and mental health. The review concludes with the importance of considering ethnicity/race and accompanying sociodemographic, environmental, and behavioral influences on sleep and mental health research.

Sleep Facilitates Coping: Moderated Mediation of Daily Sleep, Ethnic/Racial Discrimination, Stress Responses, and Adolescent Well-Being

Using a daily diary design and actigraphy sleep data across 2 weeks among 256 ethnic/racial minority adolescents (Mage  = 14.72; 40% Asian, 22% Black, 38% Latinx; 2,607 days), this study investigated how previous-night sleep (duration, quality) moderated the same-day associations between ethnic/racial discrimination and stress responses (rumination, problem solving, family/peer support seeking) to predict daily well-being (mood, somatic symptoms, life satisfaction). On days when adolescents experienced greater discrimination, if they slept longer and better the previous night, adolescents engaged in greater active coping (problem solving, peer support seeking), and subsequently had better well-being. Adolescents also ruminated less when they slept longer the previous night regardless of discrimination. Findings highlight the role of sleep in helping adolescents navigate discrimination by facilitating coping processes.

Discrimination and Sleep Mediate Ethnic/Racial Identity and Adolescent Adjustment: Uncovering Change Processes With Slope-as-Mediator Mediation

This study employs slope-as-mediator techniques to explore how the daily association between ethnic/racial discrimination and sleep disturbances serves as an intermediary link between ethnic/racial identity (ERI) and psychological adjustment. In a diverse sample of 264 adolescents (Mage  = 14.3 years old, 70% female, 76% United States born, 25% African American, 32% Asian American, 43% Latinx), discrimination was associated with sleep disturbance. Furthermore, ERI commitment buffered the impact of discrimination on sleep, whereas ERI exploration exacerbated the impact of discrimination. Finally, the daily level association between discrimination and sleep (i.e., daily slope) mediated the association between ERI and adolescent adjustment. Substantive links between discrimination and sleep are discussed as well as broader applications of slope-as-mediator techniques.

Racial Disparities in Sleep: Associations With Discrimination Among Ethnic/Racial Minority Adolescents

This study investigates the same-day associations between discrimination and sleep among 350 adolescents ages 13-15 (M = 14.29, SD = 0.65; Asian = 41%, Black = 22%, Latinx = 37%). Assessing sleep duration, sleep onset latency, and wake minutes after sleep onset using wrist actigraphy, Black adolescents slept 35 min less than Asian and 36 min less than Latinx youth. Black adolescents suffered the most wake minutes after sleep onset, followed by Latinx and Asian youth. Latinx youth reported the highest levels of sleep disturbance, whereas Asian youth reported the highest levels of daytime dysfunction. Daily discrimination was associated with lower levels of same-night sleep onset latency, more sleep disturbance, more next-day daytime dysfunction, and higher next-day daytime sleepiness.
