Left In The (Road) Dust: Analyzing Advanced Clean Cars Ii In California’S Disadvantaged Communities, Jj Hoffman

Pomona Senior Theses

Across the United States, air pollution disproportionately impacts minority groups. California’s Advanced Clean Cars II (ACC II) waiver was positioned to lead to significant environmental justice impacts, such as reductions in emissions and adverse health outcomes, by establishing stricter regulations for vehicle emissions and ensuring that 100 percent of new passenger vehicle sales are zero-emission by 2035. As the federal government recently nullified ACC II, pollution, and by extension health, could worsen, especially in disadvantaged communities. The thesis established several important relationships, including how disadvantaged communities experienced higher traffic, pollution, and worse health outcomes than non-disadvantaged communities. Though the results …

Racial Disparities In Maternal Mortality: The Role Of Explicit And Implicit Bias In U.S. Healthcare, Lailah Allen

Capstone Showcase

Maternal mortality in the United States remains a critical public health crisis, with disproportionately high rates among Black and other minority women. Despite advances in obstetric medicine, racial disparities in pregnancy-related deaths persist due to structural inequities, implicit bias in healthcare delivery, unequal access to prenatal and postpartum care, and broader social determinants of health. Nationally, Black women are significantly more likely to experience severe maternal morbidity and mortality compared to White women, reflecting longstanding inequities embedded within the healthcare system. This paper examines the relationship between race, healthcare access, and maternal outcomes through a focused case study of and …

The Effect Of The Affordable Care Act Medicaid Expansion On The Risk Of Hospital Closure And Adolescent Hpv Immunization In Rural Counties, Juliette Des Rosiers

Scripps Senior Theses

From 2005 to 2025, over 200 rural hospitals shut their doors, often citing increased operational costs, staffing shortages, low patient volume, regulatory barriers, financial challenges exacerbated by the COVID-19 pandemic, and uncompensated care as common contributors to the closures. Rural patients are often referred by their primary care physician to a hospital for regular immunizations, since smaller clinics have less capacity to provide immunizations due to a shortage of pediatricians and limited vaccine stock. A crucial vaccine that is not required by schools and underutilized in rural areas is that against human papillomavirus (HPV), a virus that infects cutaneous and …

Improving Maternal Health: Investigating The Early Impacts Of Medicaid Coverage Of Doulas In Oregon, Miriam Akhmetshin

Scripps Senior Theses

While the U.S. spends more per-capita than any country on healthcare, we experience the worst maternal health outcomes of high-income nations. In addition to hefty healthcare bills, an overwhelming majority of mothers experience pregnancy-related health issues that decrease productivity and utility. Thus, it is critical to research cost-effective solutions that can improve maternal health and promote equitable outcomes. Doulas are trained non-medical professionals who support mothers and families before, during and after birth. As a growing body of medical literature points to the role of doulas in decreasing costly medical interventions, insurance companies have begun covering their services. In 2014, …

Food Stamp Participation And Health Outcomes In Ca Immigrants, Esther Kang

Scripps Senior Theses

The U.S. social welfare system includes programs aiming to increase access to nutritious food to reduce nutrition insecurity. However, studies suggest that immigrants continue to face disproportionate risks of nutrition insecurity and may face barriers to enrollment due to legal status. This study, using secondary data from the 2023 California Health Interview Survey, examines the associations between food stamp participation, food insecurity, and clinical diagnosis of diabetes among adult U.S.-born, naturalized, and non-citizen adults in California. The findings suggest that those enrolled in food stamps are more likely to report food insecurity than those who are not enrolled, and that …

Health Care Governance And Structural Exclusion In Florida: A Human Rights Analysis Of Access For Latinx Communities, Natalie Medrano

Honors Undergraduate Theses

Access to health care in the United States is a complex system shaped by statutory programs and the discretionary powers of state governance. This thesis examines how Florida’s healthcare system structures access through administrative design, with particular attention to its impact on Latinx communities. Although formally race-neutral, Florida’s reliance on Medicaid non-expansion, managed care delivery, and complex eligibility processes produces systemic barriers that limit access for low-income populations. Drawing on the international right-to-health framework articulated in General Comment No. 14 of the International Covenant on Economic, Social and Cultural Rights, alongside Latinx Critical Race Theory (LatCrit), this study analyzes how …

The Knowledge, Experiences, And Attitudes Of Nurses Regarding Trauma-Informed Care For Sexually Abused Intrapartum Patients, Kayleigh Mcgraw

Honors Undergraduate Theses

Labor and delivery nurses care for women from diverse backgrounds who are preparing for a life-changing event, often marked by fear, excitement, sadness, and joy. However, 1 in 5 women in the United States have experienced rape or attempted rape, and for these survivors, labor can become re-traumatizing. Many report flashbacks, dissociation, and a sense of “being back in the rape” during childbirth. Research further links prior sexual assault to unplanned cesareans, traumatic births, and childbirth-related PTSD. Trauma-informed care (TIC) provides a framework to reduce these risks by encouraging providers to understand trauma, recognize signs of distress, and act to …

From Coverage To Care: Evaluating The Effects Of Aca Medicaid Expansion On Birth Outcomes, Bailey R. Lengfelder

Economics Honors Projects

I examine the impact of the Affordable Care Act’s Medicaid expansion on maternal and fetal health outcomes using National Center for Health Statistics Natality data from 2006 to 2023. I exploit staggered state adoption as a quasi-experiment, and the staggered differences-in-differences estimates indicate an increase in the share of Medicaid births but broadly no impact on maternal prenatal care, maternal health, and fetal health. The absence of statistically significant effects is consistent across heterogeneity groups. These null findings indicate that expanded insurance access through the Affordable Care Act may be insufficient to improve health outcomes. I do find a statistically …

24-H Circadian Rest-Activity Rhythms And Physical Frailty In Older Adults: A Biopsychosocial Perspective On Sex Differences And Social Capital, Jisu Kim

Theses and Dissertations

Physical frailty is a prevalent geriatric syndrome characterized by age-related decline across multiple physiological systems. Physical frailty is associated with an elevated risk of adverse health outcomes, including chronic disease progression and all-cause mortality, representing a significant and growing public health concern. Disrupted circadian rest-activity rhythms (RARs) are increasingly recognized as clinically meaningful markers of physical frailty in older adults. However, the extent to which biological sex and social determinants of health (SDoH), particularly social capital, contribute to or modify the associations between RARs and physical frailty remains underexplored.

Therefore, this dissertation summarizes the existing literature on age-related changes in …
