Prenatal exposure to fine particulate matter chemical constituents and the risk of stillbirth and the mediating role of pregnancy complications: A cohort study

Evidence on the association of fine particulate matter (PM2.5) exposure with stillbirth is limited and inconsistent, which is largely attributed to differences in PM2.5 constituents. Studies have found that the hazards of certain PM2.5 constituents to the fetus are comparable to or even higher than total PM2.5 mass. However, few studies have linked PM2.5 constituents to stillbirth. Moreover, the mediating role of pregnancy complications in PM2.5-related stillbirth remains unclear. To our knowledge, this study was the first to explore the individual and mixed associations of PM2.5 and its constituents with stillbirth in China. After matching the concentrations of PM2.5 and its constituents (sulfate [SO42-], nitrate [NO3-], ammonium [NH4+], organic matter [OM], and black carbon [BC]) for participants according to their geographical location, there were 170,507 participants included in this study. We found that stillbirth was associated with exposure to PM2.5 and its constituents in the year before pregnancy and during the entire pregnancy, and the associations in trimester 1 were strongest. The risk of stillbirth increased sharply when PM2.5 and its constituents during pregnancy exceeded the median concentrations. Moreover, stillbirth was associated with exposure to the mixtures of SO42-, NO3-, NH4+, OM, and BC before and during pregnancy (trimesters 1 and 2). Meanwhile, two-pollutant models also suggested stillbirth was associated with PM2.5 and its constituents in the year before and during pregnancy. The associations of PM2.5 and its constituents with stillbirth were stronger in mothers with advanced age and without cesarean delivery history. Additionally, hypertensive disorders in pregnancy, gestational diabetes, and placental abruption mediated the association of PM2.5 with stillbirth. Therefore, enhanced protection against PM2.5 for pregnant women before and during pregnancy and targeted interventions for pregnancy complications and anthropogenic sources of PM2.5 constituents are important to reduce stillbirth risk.

Gendered racial microaggressions and emerging adult Black women's social and general anxiety: Distress intolerance and stress as mediators

There is robust evidence that gendered racial microaggressions affect Black women's mental health. However, few studies have examined how this form of discrimination affects Black women's social anxiety in addition to their general anxiety, as well as the underlying mechanisms related to gendered racial microaggressions and anxiety.

OBJECTIVE

The purpose of this study was to examine the associations between gendered racial microaggressions stress (GRMS) and gendered racial microaggressions frequency (GRMF), and Black women's social anxiety and general anxiety symptoms. We also examined the mediating roles of distress intolerance and stress in these associations.

METHOD

One hundred and sixty-three Black women, between the ages of 18 and 25 years old, completed a cross-sectional survey. Regression analyses were used to examine the associations between gendered racial microaggressions and social anxiety and general anxiety, and mediation analyses examined the indirect effect of gendered racial microaggressions on the outcome variables through distress intolerance and stress.

RESULTS

GRMS was associated with greater social and general anxiety through the mechanisms of distress intolerance and stress. GRMF was associated with reduced social anxiety and was not associated with general anxiety.

CONCLUSIONS

Intervention efforts should be aimed to prevent the experience of gendered racial microaggressions to prevent subsequent stress and mental health outcomes for Black women.

Campus Sexual Harassment, Other Violence, and Racism, Oh my! Evidence From Black Women Undergraduates for a Culturally Competent University Approach to Title IX

Relevant for Title IX federal legislation, the purpose of the current study is to examine cultural betrayal (within-group perpetrator) and sexual harassment (SH) with other violence and racial discrimination on Black women undergraduates' mental health. In a 60-minute online study (N = 162), over 50% experienced campus SH and other violence and/or racial discrimination, with multi-victimization being related to anxiety and other mental health outcomes. Cultural betrayal SH did not predict mental health when controlling for between-group SH. Implications include the 2019 Critical-Interdisciplinary Sexual Violence Research Summit's comprehensive research agenda: Intersectional Approaches, Perpetration, Communications, Beyond Policy, and Sexual Violence and Equity.

Ethnic discrimination and psychological stress among Hispanic emerging adults: Examining the moderating effects of distress tolerance and optimism

Hispanic emerging adults are often exposed to ethnic discrimination, yet little is known about coping resources that may mitigate the effects of ethnic discrimination on psychological stress in this rapidly growing population. As such, this study aims to examine (1) the associations of ethnic discrimination, distress tolerance, and optimism with psychological stress and (2) the moderating effects of distress tolerance and optimism on the association between ethnic discrimination and psychological stress. Data were drawn from a cross-sectional study of 200 Hispanic adults ages 18-25, recruited from two urban counties in Arizona and Florida. Hierarchical multiple regression and moderation analyses were utilized to examine these associations and moderated effects. Findings indicated that higher optimism was associated with lower psychological stress. Conversely, higher ethnic discrimination was associated with higher psychological stress. Moderation analyses indicated that both distress tolerance and optimism moderated the association between ethnic discrimination and psychological stress. These study findings add to the limited literature on ethnic discrimination among Hispanic emerging adults and suggest that distress tolerance may be a key intrapersonal factor that can protect Hispanic emerging adults against the psychological stress often resulting from ethnic discrimination.
