Discrimination is associated with poor sleep quality in pregnant Black American women.

BACKGROUND: Heightened exposure to racial/ethnic discrimination is associated with poorer sleep health among non-pregnant adults. This relationship has received limited research attention among pregnant women, despite the importance of prenatal sleep quality for optimal maternal and child health outcomes. METHODS: We utilized perinatal data from a sample of Black American women (n = 600) participating in a cohort study who reported their lifetime experiences of racial/ethnic discrimination and gendered racial stress during early pregnancy and reported on their sleep quality and depressive symptoms during early and mid-pregnancy. Hierarchical multiple linear regression models were fit to examine associations between lifetime experiences of racial/ethnic discrimination or gendered racial stress and sleep quality during early and mid-pregnancy. We also adjusted for women's concurrent depressive symptoms and tested whether the discrimination/sleep quality association varied by socioeconomic status. RESULTS: Greater exposure to racial/ethnic discrimination was associated with poorer sleep quality during early (ΔR2 = 0.04, ΔF = 26.08, p < 0.001) and mid-pregnancy (ΔR2 = 0.02, ΔF = 9.88, p = 0.002). Similarly, greater gendered racial stress was associated with poorer sleep quality during early (ΔR2 = 0.10, ΔF = 65.72, p < 0.001) and mid-pregnancy (ΔR2 = 0.06, ΔF = 40.43, p < 0.001. These findings largely held after adjustment for concurrent prenatal depressive symptoms. Socioeconomic status did not modify the observed relationships. CONCLUSIONS: Efforts to decrease institutional and interpersonal experiences of racial/ethnic discrimination and gendered racism would benefit the sleep quality of pregnant Black American women, particularly during early pregnancy.

Intergenerational Effects of Discrimination on Black American Children's Sleep Health.

Greater exposure to racial/ethnic discrimination among pregnant Black American women is associated with elevated prenatal depressive symptomatology, poorer prenatal sleep quality, and poorer child health outcomes. Given the transdiagnostic importance of early childhood sleep health, we examined associations between pregnant women's lifetime exposure to racial/ethnic discrimination and their two-year-old children's sleep health. We also examined women's gendered racial stress as a predictor variable. In exploratory analyses, we examined prenatal sleep quality and prenatal depressive symptoms as potential mediators of the prior associations. We utilized data from a sample of Black American women and children (n = 205). Women self-reported their lifetime experiences of discrimination during early pregnancy, their sleep quality and depressive symptoms during mid-pregnancy, and their children's sleep health at age two. Hierarchical linear multiple regression models were fit to examine direct associations between women's experiences of discrimination and children's sleep health. We tested our mediation hypotheses using a parallel mediator model. Higher levels of gendered racial stress, but not racial/ethnic discrimination, were directly associated with poorer sleep health in children. Higher levels of racial/ethnic discrimination were indirectly associated with poorer sleep health in children, via women's prenatal depressive symptomatology, but not prenatal sleep quality. Clinical efforts to mitigate the effects of discrimination on Black American women may benefit women's prenatal mental health and their children's sleep health.

Psychological Distress Prospectively Predicts Later Sleep Quality in a Sample of Black American Postpartum Mothers.

Objective: Previous longitudinal studies have demonstrated prospective relationships between maternal sleep quality and subsequent psychological distress in the postpartum period. Despite evidence for prospective relationships between mood and subsequent sleep quality in adult populations, this direction has not been examined in postpartum women. We aimed to test prospective relationships between sleep quality and subsequent psychological distress, as well as the plausible reverse possibility, in a sample of Black American postpartum mothers (n = 146).Participants: Mothers were recruited prenatally from two hospitals in a Southeastern city of the United States. Eligible and interested mothers enrolled in a follow-up study on infant development. Data from the current study were obtained during the follow-up study.Method: Mothers reported on their psychological distress (i.e., anxiety, depression, stress) and sleep quality at 3- and 6-months postpartum. We performed hierarchical linear regressions to explore whether 1) maternal sleep quality at 3-months postpartum would predict maternal psychological distress at 6-months postpartum, after adjustment for mothers' earlier psychological distress, and 2) whether psychological distress at 3-months postpartum would predict maternal sleep quality at 6-months postpartum, after adjustment for mothers' earlier sleep quality.Results: Maternal sleep quality at 3-months postpartum was not a significant predictor of psychological distress at 6-months postpartum. However, maternal psychological distress at 3-months postpartum was a significant predictor of sleep quality at 6-months postpartum.Conclusions: Mothers' psychological distress earlier in the postpartum was a significant predictor of their later sleep quality. Replication is needed in large, prospective studies, with results stratified by race/ethnicity.

Intergenerational Impacts of Maternal Stress on Early Childhood Atopy in Black Americans.

OBJECTIVE: Black children are disproportionately affected by atopic diseases (i.e., atopic dermatitis, allergic rhinitis, asthma, and food allergies), with health disparities present in early life. Studies in White samples suggest that maternal stress confers risk for offspring atopy, yet little is known about these relationships in Black populations. This study seeks to (a) examine the relationship between self-reported and physiological indicators of maternal stress and offspring atopy and (b) explore warm and responsive caregiving as a potential protective factor in Black Americans. METHODS: A sample of 179 Black mother-child dyads of varying socioeconomic status participated in a prospective longitudinal study. Mothers completed self-reports of childhood trauma, prenatal stress, postnatal stress, and physician diagnosis of offspring atopy; provided blood samples to assess physiological responses to chronic stress exposure; and participated in a behavioral task with their infant. RESULTS: Maternal self-reports of childhood trauma, prenatal stress, and postnatal stress were not associated with offspring diagnosis of atopy by 2-3 years of age. Mothers who produced a smaller inflammatory response during pregnancy were more likely to have an offspring with atopy by 2-3 years of age. Warm and responsive parenting demonstrated a protective effect; the positive association between maternal stress and offspring atopy was less apparent in cases of mother-child interactions characterized by high levels warm and responsive parenting. CONCLUSION: Failure to replicate previous findings suggests that the maternal stress-offspring atopy relationship is complex. Future studies must examine the unique stressors in Black Americans, as well as caregiving as a potential protective factor.
