Within-person associations between racial microaggressions and sleep among African American and Latinx young adults

Microaggression and discrimination exposure on young adult anxiety, depression, and sleep

BACKGROUND

Increasing research examines social determinants of health, including structural oppression and discrimination. Microaggression - subtle/ambiguous slights against one's marginalized identity - is distinct from discrimination, which typically presents as overt and hostile. The current study investigated the comparative effects of each exposure on young adult anxiety, depression, and sleep. Race-stratified analyses investigated patterns across groups.

METHODS

Young adults (N = 48,606) completed the Spring 2022 American College Health Association-National College Health Assessment III. Logistic regressions tested odds of anxiety symptoms, depressive symptoms, and sleep disturbance in association with microaggression and discrimination exposure.

RESULTS

Microaggression and discrimination equally predicted increased likelihood of anxiety symptoms (ORMicro = 1.42, ORDiscrim = 1.46). Discrimination more strongly predicted depressive symptoms (OR = 1.59) and sleep disturbance (OR = 1.54) than did microaggression (ORDepress = 1.24, ORSleep = 1.27). Race-stratified analyses indicated stronger associations between the each exposure and poor mental health in Whites than Asian American, Black/African American, and Hispanic or Latino/a/x respondents.

LIMITATIONS

Microaggression and discrimination exposure were each assessed using a single item. The outcome measures were not assessed using validated measures of anxiety, depression, and sleep (e.g., GAD-7, MOS-SS); thus results should be interpreted with caution. Analyses were cross-sectional hindering our ability to make causal inferences.

CONCLUSIONS

The findings provide preliminary evidence that microaggression and discrimination exposure operate on health in distinct ways. Racially marginalized individuals may demonstrate a blunted stress response relative to Whites. Treatment approaches must be tailored to the particular exposures facing affected individuals to maximize benefits.

Sleep, Health Outcomes and Body Weight (SHOW) study: a measurement burst design study on sleep and risk factors for obesity in black emerging adults in North Carolina, USA

INTRODUCTION

Black emerging adults (18-28 years) have the highest risk of short sleep duration and obesity. This increased risk may be partly explained by greater stress levels, which may result from race-related stress (racial discrimination and heightened race-related vigilance) or living in more disadvantaged home and neighbourhood environments. Insufficient sleep may also impact obesity risk via several weight-related mechanisms including energy balance, appetite and food reward, cortisol profiles and hydration status. This paper describes the rationale, design and methods for the Sleep, Health Outcomes and Body Weight (SHOW) study. This study aims to prospectively assess the effects of sleep, race-related stress and home/neighbourhood environments on weight-related mechanisms and obesity markers (body weight, waist circumference and fat mass) in 150 black emerging adults.

METHODS AND ANALYSIS

The SHOW study follows a measurement burst design that includes 3, 7-day data collection bursts (baseline, 6-month and 12-month follow-ups). Sleep is measured with three methods: sleep diary, actigraphy and polysomnography. Energy balance over 7 days is based on resting and postprandial energy expenditure measured via indirect calorimetry, physical activity via accelerometry and self-reported and ad libitum energy intake methods. Self-reported methods and blood biomarkers assess fasting and postprandial appetite profiles and a behavioural-choice task measures food reward. Cortisol awakening response and diurnal cortisol profiles over 3 days are assessed via saliva samples and chronic cortisol exposure via a hair sample. Hydration markers are assessed with 24-hour urine collection over 3 days and fasting blood biomarkers. Race-related stress is self-reported over 7 days. Home and neighbourhood environments (via the Windshield Survey) is observer assessed.

ETHICS AND DISSEMINATION

Ethics approval was granted by the University of North Carolina at Greensboro's Institutional Review Board. Study findings will be disseminated through peer-reviewed publications, presentations at scientific meetings and reports, briefs/infographics for lay and community audiences.

Rumination mediates associations between microaggressions and sleep quality in Black Americans: the toll of racial microstressors

Disparities in health outcomes between Black and White Americans are well-documented, including sleep quality, and disparities in sleep may lead to disparities in health over the life course. A meta-model indicates that cognitive processes may underly the connection between race and poor sleep quality, and ultimately, health disparities. That is, there are race-specific stressors that disproportionately affect Black Americans, which are associated with poor health through biological, cognitive, and behavioral mechanisms (e.g., sleep). Among these race-specific stressors is discrimination, which has been linked to poor sleep quality, and there is a body of literature connecting perseverative cognition (e.g., rumination and worry or vigilance) to poor sleep. Microaggressions, a more subtle but pervasive form of discrimination, are another race-specific stressor. Although less research has considered the connection of microaggressions to perseverative cognition, there are some studies linking microaggressions to health outcomes and sleep. Therefore, using a cross-sectional survey, we tested the following hypotheses: racism-related vigilance and rumination would mediate the relationship between discrimination and poor sleep as well as between microaggressions and poor sleep among Black Americans (N = 223; mean age = 35.77 years, 53.8% men, 86% employed, 66.8% with college degree or higher education). Results of seven parallel mediation models showed that neither rumination nor racism-related vigilance mediated a relationship between discrimination and poor sleep quality. However, rumination partially mediated relationships between the six microaggression sub-scales and poor sleep quality: there were significant indirect effects for Foreigner/Not Belonging (β = .13, SE = 0.03, 95% CI 0.08, 0.20), Criminality (β = .11, SE = 0.03, 95% CI 0.05, 0.17), Sexualization (β = .10, SE = 0.03, 95% CI 0.05, 0.17), Low-Achieving/Undesirable (β = .10, SE = 0.03, 95% CI 0.05, 0.15), Invisibility (β = .15, SE = 0.04, 95% CI 0.08, 0.23), and Environmental Invalidations (β = .15, SE = 0.04, 95% CI 0.08, 0.23). Overall, these findings indicate support for the meta-model, demonstrating a specific pathway from racial microstressors to poor sleep quality. Furthermore, these results suggest the importance of developing clinical and community approaches to address the impact of microaggressions on Black Americans' sleep quality.

Microaggressions, perceptions of campus climate, mental health, and alcohol use among first-year college students of color

Depressive and anxiety symptoms are increasingly common, and problematic alcohol use remains prevalent in college. To expand on prior research on mostly white samples, we surveyed first-year students of color from our predominately white university (Southeastern US) to identify risk factors for mental health symptoms and potentially co-occurring problematic alcohol use. Results showed significant associations between microaggressions and poor campus climate (hypothetical predictors) with depressive, anxiety, somatic symptoms (hypothetical outcomes) that were indirectly linked through perceived stress, poor sleep, and academic burnout (hypothetical mediators). Poor campus climate, academic burnout, and using alcohol to cope were the most relevant to alcohol use disorder symptoms. Results support efforts to address and reduce racial microaggressions and promote a positive campus climate for all.

Not Just Time on Social Media: Experiences of Online Racial/Ethnic Discrimination and Worse Sleep Quality for Black, Latinx, Asian, and Multi-racial Young Adults

Sleep quality in young adulthood sets the stage for long-term health. Racial/ethnic sleep disparities between White college-attending young adults and college-attending young adults of color exist. The stress of experiencing racial/ethnic discrimination makes it difficult for college-attending young adults of color to get good quality sleep. Yet it remains unclear if experiencing online racial/ethnic discrimination also has consequences for sleep quality, and if this association may vary by frequency of social media use. To investigate the role of racial/ethnic discrimination on sleep quality, we conducted an online survey of 154 college-attending young adults (Mage = 19.51) who identified as Black (42.2%), Latinx (16.9%), Asian (20.8%), or Bi-/multi-racial (20.1%) from a predominantly White university. Results indicated that more exposure to racial/ethnic discrimination was associated with worse sleep quality for young adults of color. Results suggest that online racial/ethnic discrimination has a similar negative impact on sleep quality regardless of the frequency of social media use. Increased attention to negative race-related experiences online as one potential risk factor for poor long-term health for young adults of color is needed, regardless of how many hours they spend on social media. Structural interventions, screening for stress due to exposure to online racial/ethnic discrimination, and facilitating opportunities to prepare for this exposure may be an important priority for sleep health and reduction of racial/ethnic health disparities.

Disparities in Sleep-Disordered Breathing: Upstream Risk Factors, Mechanisms, and Implications

Sleep-disordered breathing (SDB) refers to a spectrum of disorders ranging from habitual snoring without frank episodes of obstructed breathing or desaturation during sleep to obstructive sleep apnea, where apneas and hypopneas repetitively occur with resultant intermittent hypoxia, arousal, and sleep disruption. Disparities in SDB reflect its overall high prevalence in children and adults from racially and ethnically minoritized or low socioeconomic status backgrounds coupled with high rates of underdiagnosis and suboptimal treatment.

Does ethnic-racial socialization matter? A within-person analysis of racial discrimination and sleep health among Black and Latinx emerging adults

OBJECTIVES

Emerging work suggests that racism-related stressors may contribute to adverse sleep health, yet little is known about how culturally relevant resources may influence the relationship between racism-related stressors and adverse sleep health. The aim of this study was to examine associations between weekly reports of racial hassles and young adults' sleep health (i.e., sleep onset latency, total sleep time, sleep quality) and to determine whether various forms of parental ethnic-racial socialization would moderate these associations.

METHODS

Participants were 141 college students (Mage = 20.7 years, standard deviation (SD) = 1.22, 70% female) who identified as either Black (n = 88; 62.4%) or Latinx (n = 53; 37.6%). Participants completed an initial 1.5-hour assessment in the laboratory and 4 weekly sleep diary surveys (assessed sleep health and depressive symptoms).

RESULTS

Weekly racial hassles are related to greater sleep onset latency, decreased total sleep time, and poorer sleep quality. The promotion of mistrust and cultural socialization significantly moderated associations between weekly racial hassles and sleep onset latency and total sleep time, respectively.

CONCLUSIONS

These results provide supportive evidence that parental ethnic-racial socialization practices, a preemptive cultural resource, may be an understudied mechanism in sleep health research. Future research is needed to clarify the role of parental ethnic-racial socialization in promoting sleep health equity among youth and young adults.

Gendered Racial Microaggressions and Black Women's Sleep Health

Gendered racial microaggressions reflect historical and contemporary gendered racism that Black women encounter. Although gendered racial microaggressions are related to psychological outcomes, it is unclear if such experiences are related to sleep health. Moreover, the health effects of gendered racial microaggressions dimensions are rarely investigated. Using a cohort of Black women (N = 400), this study employs an intracategorical intersectional approach to (1) investigate the association between gendered racial microaggressions and sleep health, (2) assess whether gendered racial microaggressions dimensions are related to sleep health, and (3) examine whether the gendered racial microaggressions-sleep health association persists after accounting for depressive symptoms and worry. Gendered racial microaggressions were associated with poor sleep quality overall and four specific domains: subjective sleep quality, latency, disturbance, and daytime sleepiness. Two gendered racial microaggressions dimensions were especially detrimental for sleep: assumptions of beauty/sexual objectification and feeling silenced and marginalized. After accounting for mental health, the effect of gendered racial microaggressions on sleep was reduced by 47 percent. Future research implications are discussed.

Racial Disparities in Sleep: Potential Mediation by Discrimination and Psychological Distress

Previous research has demonstrated that experiences of discrimination contribute to racial disparities in sleep, and that psychological distress mediates these relationships. However, previous research has not included race as part of the mediation pathway and has had limited dimensions of sleep health and psychological mediators. In the current study, we examine serial mediation pathways by which race and sleep health are mediated through discrimination and subsequently through psychological distress (i.e., depressive symptoms, chronic stress, and loneliness). Data were from the 2010 wave of the Health Retirement Study (HRS). The analytic sample (n = 7,749) included Black and White participants who were included in the enhanced face-to-face interview in 2010 and who completed the psychosocial questionnaire. Race was reported as either Black or White. Sleep health was assessed with a 4-item questionnaire. Depressive symptoms were assessed with the shortened CES-D, chronic stress via the ongoing chronic stressor scale, and loneliness via the UCLA loneliness scale. Covariates were included in all serial mediation models. Relative to White participants, Black participants reported increased experiences of discrimination, which was associated with increased psychological distress, and poorer sleep health. Findings demonstrate the significant adverse impact that discrimination has on both psychological well-being and sleep health.

Sleep disparities in Asian Americans: a comprehensive review

STUDY OBJECTIVES

This review summarizes race-based sleep health disparities between Asian Americans and other American racial groups and compares sleep outcomes between Asian American subgroups disaggregated by ethnicity and ancestral national origin. The study identifies gaps in the existing literature, analyzes barriers to studying Asian American sleep, and recommends topics for future research.

METHODS

A PubMed review of research on adult Asian American sleep was conducted. The articles included utilized actigraphy, polysomnography, and questionnaires to gather sleep health metrics. Information from these articles included data on sleep duration, sleep quality, sleep disturbances, and sleep disorders.

RESULTS

Most aggregated studies find Asian American adults experiencing lower sleep duration and poorer sleep quality compared to non-Hispanic White Americans and comparable or slightly higher sleep duration compared to Black Americans. Within Asian Americans, first-generation immigrants report better sleep quality than subsequent generations. East Asian Americans may experience better sleep outcomes compared to Southeast Asian Americans. Obstructive sleep apnea is critically underreported in South Asian Americans.

CONCLUSIONS

Significantly more research is required in Asian American sleep disparities, specifically in South and Southeast Asian Americans. Sleep disparities between Asian Americans and other racial groups are impacted by perceived discrimination, poor mental health, and cultural attitudes toward sleep. The observed within-group disparities of Asian American sleep may be attributed to socioeconomic status and generational status/acculturation. Existing barriers to research include the model minority myth and lack of disaggregated racial sleep data.

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.

Coping with Ethnic-racial Discrimination: Short-term Longitudinal Relations Among Black and Latinx College Students

Little is known about how Black and Latinx young adults cope with experiences of ethnic-racial discrimination, particularly over short periods of time. A multigroup path model examined the relations between discrimination and five strategies for coping with ethnic-racial discrimination (talking with others, being proud, working hard, being rude, and ignoring) among Black and Latinx young adults (N = 145) at two time points over a six-week period. Experiences of discrimination were positively associated with the coping strategies of being proud of oneself and working hard to prove discriminatory people wrong. There was moderate stability in coping strategy use over time. Models did not vary by race-ethnicity, suggesting discrimination related to coping in similar ways among Black and Latinx young adults.

Immediate and delayed effects of everyday racial discrimination on mental health among Black college students: A mixed-methods approach

Experiences of racial discrimination significantly contribute to both mental and physical health outcomes. In this mixed-methods study, we examine both the immediate and delayed effect of discrimination experienced in daily life. Black students at a predominantly White university reported instances of racial discrimination, affect, anxiety, and depression several times per day over 4 weeks ( N = 114); this was followed by qualitative focus groups ( N = 25). Reporting an instance of discrimination corresponded with an acute decline in psychological wellbeing (higher negative affect, anxiety, and depression), consistent with previous work. However, this effect did not carry forward to later assessments during the same day or the following day as expected. Instead, positive affect temporarily increased in the hours following experiences of discrimination. Qualitative focus groups revealed social support, emotional reflection and processing, and feelings of taking action as important factors contributing to this bump in positive affect.

A protocol for applying health equity-informed implementation science models and frameworks to adapt a sleep intervention for adolescents at risk for suicidal thoughts and behaviors

Background

Effective and equitable strategies to prevent youth suicidal thoughts and behaviors (STB) are an urgent public health priority. Adolescent sleep disturbances are robustly linked to STB but are rarely addressed in preventive interventions or among Black and/or Hispanic/Latinx youth for whom STB risk is increasing disproportionately. This paper describes an application of health equity-informed implementation science models and frameworks to adapt and evaluate the evidence-based Transdiagnostic Sleep and Circadian (TSC) intervention for primary care implementation with adolescents of minoritized backgrounds with depression and STB risk.

Methods

This multiphase study protocol uses the Assessment, Decision, Adaptation, Production, Topical Experts-Integration, Training, Testing (ADAPT-ITT) model to adapt and evaluate TSC for primary care implementation with adolescents who are depressed, at risk for STB, and of primarily Black and/or Hispanic/Latinx backgrounds. We integrate the Consolidated Framework for Implementation Research (CFIR) in an initial qualitative inquiry of adolescent, caregiver, and clinician perceptions of TSC. Subsequent ADAPT-ITT phases include systematically and iteratively testing adaptations based on the qualitative inquiry, with ongoing key informant input, and then evaluating the adapted TSC for feasibility, acceptability, and efficacy in a pilot randomized trial.

Anticipated results

Based on youth depression and sleep health disparities research, we expect that TSC adaptations will be needed to enhance intervention content for adolescents with depression, STB risk, and primarily Black and/or Hispanic/Latinx backgrounds. We also anticipate adaptations will be needed to align TSC delivery methods with primary care implementation.

Conclusions

Adapting evidence-based interventions with end-users and contexts in mind can help ensure that intervention strategies and delivery methods are acceptable to, and feasible with, health disparate populations. Although TSC has shown effectiveness for adolescents with sleep disturbances, we expect that additional multiphase research is necessary to optimize TSC for primary care delivery with Black and/or Hispanic/Latinx adolescents with depression and STB risk.
