ROWELL, TIFFANY A., M.A. MAY 2020 PSYCHOLOGICAL SCIENCES EXAMINING THE IMPACT OF PREGNANT BLACK WOMEN’S ADVERSE CHILDHOOD EXPERIENCES THROUGH MATERNAL HEALTH AND BIRTH OUTCOMES (74 PP.) Thesis Advisor: Angela Neal-Barnett, Ph.D. In the United States, Black mothers and their infants are dying at an alarming rate compared to White, Hispanic, Asian, and Native American infants. Psychosocial factors such as socioeconomic status, racism, and trauma have been cited as contributors to this health disparity. In order to better understand potential risk factors that contribute to the rising infant mortality rate of Black babies, this study aims to examine the impact of adverse childhood experiences (ACEs) on maternal health outcomes and infant birth outcomes. It was hypothesized that maternal ACEs would predict maternal distress, BMI, and blood pressure, as well as infant gestational age and birth weight. Additionally, it was hypothesized that maternal distress, BMI, and blood pressure would moderate the relationship between ACEs and birth outcomes. Results indicated that higher ACEs predicted lower levels of distress. There were no significant relationships between ACEs and maternal BMI, maternal, blood pressure, and infant birth outcomes. Lastly, the relationship between ACEs and birth outcomes was not moderated by maternal health variables. The findings from this study support an association between childhood trauma and distress that is likely found in trauma survivors who have difficulties with regulating their emotions and accurately conceptualizing their feelings of distress. Alternatively, the results may be explained by the resiliency of the mothers in this sample. Future work should continue to i examine the relationships between ACEs and maternal health and birth outcomes to understand risk and protective factors that influence the impact of trauma on maternal and infant health. ii EXAMINING THE IMPACT OF PREGNANT BLACK WOMEN’S ADVERSE CHILDHOOD EXPERIENCES THROUGH MATERNAL HEALTH AND BIRTH OUTCOMES A thesis submitted To Kent State University in partial Fulfillment of the requirements for the Degree of Master of Arts by Tiffany A.

This rate was developed to measure a country’s health and progress, yet the United States continues to have one of the highest infant mortality rates among developed nations (Singh & Yu, 2019). One major area of concern focuses on the lives of Black infants. Black infants in the United States are far more likely to die before their first birthday compared to White, Hispanic, Asian, and Native American infants. In 2016, the infant mortality rate for Black infants was 11.4 deaths per 1,000 live births. This is greater than the 2017 national rate of 5.79 for all births (CDC, 2018). The racial/ethnic divide for infant mortality has been present since the earliest collection of this data in 1850, when the rate was 216.8 for Whites and 340 for Blacks (Haines, 2008). During this time, it was customary for infants to die due to weather, famine, war, and disease (Caplow, Hicks, Wattenberg, 2001). It was not until the 1880s when there were attempts to improve public health by implementing changes relating to hygiene, nutrition, and living conditions (Caplow, Hicks, Wattenberg, 2001). From that point forward, sewers were installed in cities, central heating became more commonplace to protect infants from the cold, and eventually, antibiotics and vaccinations were created to prevent fatal diseases. The national infant mortality rate drastically dropped as a result of these changes (Caplow, Hicks, Wattenberg, 2001). Despite the improvements in public health, Black infants were consistently dying at a higher rate compared to White infants (Haines, 2008; Singh & Yu, 2019). According to United 1 States National Vital Statistics System, between 1916 and 2017, the infant mortality rate declined annually by 3.1% for White infants and 2.6% for Black infants. This slow decline in Black infant mortality has led to a disparity that has worsened over time. For example, this gap changed from 87% in 1916, to 64% in 1950, and 112% in 2017 (Singh & Yu, 1995; Singh & Yu, 2019). The CDC (2018) cites birth defects, preterm birth, low birth weight, maternal pregnancy complications, sudden infant death syndrome, and injuries as the current leading physical causes of infant mortality. While these physical factors explain why the infant died in that moment, there are still questions about what led to these complications at birth. Literature concerning the reproductive outcomes of Black infants posit that psychological distress stress stemming various social determinants also leads to infant mortality (Dominguez, Dunkel-Schetter, Glynn, Hobel, & Sandman, 2008; Giurgescu et al., 2012; Lobel, Hamilton, & Cannella, 2008). Stress and Black Maternal and Infant Health For years, stress has proven to have harmful effects on the lives of Black women and their children (Hogue & Bremmer, 2005; Rich-Edwards et al., 2001; Rosenthal & Lobel, 2011; Pieterse, Carter, & Ray, 2013; Wadhwa et al., 2001). Chronic stress is more common and detrimental in the daily lives of Black women compared to White women (Lu, 2010; Renae Stancil, Hertz-Picciotto, Schramm, & Watt-Morse,
