Stress response asymmetries in African American emerging adults exposed to chronic social adversity

Physical and Mental Health Outcomes of Black Emerging Adults with Community Violence Exposure: An Integrative Review

Community violence exposure (CVE) and its health impact is a public health crisis. Violent crime has steadily increased over recent years and has disproportionately affected Black communities. Emerging adulthood (18-29 years old) is a vulnerable period of development and Black emerging adults may be at increased risk for negative physical and mental health consequences from CVE. This integrative review was conducted to evaluate available evidence on health outcomes in Black emerging adults exposed to CVE. This review appraised published studies (2012-2022) addressing physical and mental health outcomes of Black emerging adults with CVE. Articles were identified using structured search terms in several databases (CINAHL, PubMed, PsycInfo, and Web of Science), a gray literature search, and citation mining. A total of 177 studies were identified for screening and 19 studies met inclusion criteria and were included in the review. The majority of studies found a significant positive association between CVE and adverse mental (n = 12) and physical (n = 7) health outcomes. CVE appears to have both mental and physical health consequences for Black emerging adults. Given that violent crime disproportionately increased in Black communities and Black people are more likely to develop chronic health conditions at younger ages, more work is needed to elucidate the relationship between CVE and health outcomes.

Decreased salivary alpha-amylase reactivity for excluded young women after a speech task

Salivary alpha-amylase (sAA) has gained popularity as an easily collected biomarker for sympathetic nervous system activation, and research has shown increases in sAA after completing experimental stress tasks in certain groups. However, recent work suggests that salivary cortisol, another stress biomarker, is suppressed after a speech task among experimentally induced exclusion in young women. The present analysis investigated the sAA response in biologically female undergraduates (n=31) who completed a game of Cyberball and then a speech anticipation task. Results showed that women in the social exclusion experimental group had a greater decrease in sAA compared to young women in the inclusion group after the speech task. Results of this study provide support for stress response suppression in women who have experienced social exclusion. The present findings provide pilot evidence for future, larger studies to advance the tend-and-befriend theory.

Social Determinants of Cardiovascular Disease

Social determinants of health (SDoH), which encompass the economic, social, environmental, and psychosocial factors that influence health, play a significant role in the development of cardiovascular disease (CVD) risk factors as well as CVD morbidity and mortality. The COVID-19 pandemic and the current social justice movement sparked by the death of George Floyd have laid bare long-existing health inequities in our society driven by SDoH. Despite a recent focus on these structural drivers of health disparities, the impact of SDoH on cardiovascular health and CVD outcomes remains understudied and incompletely understood. To further investigate the mechanisms connecting SDoH and CVD, and ultimately design targeted and effective interventions, it is important to foster interdisciplinary efforts that incorporate translational, epidemiological, and clinical research in examining SDoH-CVD relationships. This review aims to facilitate research coordination and intervention development by providing an evidence-based framework for SDoH rooted in the lived experiences of marginalized populations. Our framework highlights critical structural/socioeconomic, environmental, and psychosocial factors most strongly associated with CVD and explores several of the underlying biologic mechanisms connecting SDoH to CVD pathogenesis, including excess stress hormones, inflammation, immune cell function, and cellular aging. We present landmark studies and recent findings about SDoH in our framework, with careful consideration of the constructs and measures utilized. Finally, we provide a roadmap for future SDoH research focused on individual, clinical, and policy approaches directed towards developing multilevel community-engaged interventions to promote cardiovascular health.
