Accounting For The Uncertainty Due To Chemicals Below The Detection Limit In Mixture Analysis, Paul M. Hargarten Jan 2020

Accounting For The Uncertainty Due To Chemicals Below The Detection Limit In Mixture Analysis, Paul M. Hargarten

Theses and Dissertations

Humans are exposed to multiple chemicals every day. Epidemiological studies have shown that chemical mixtures are associated with cancers, allergies, neurodevelopmental disorders, and other adverse health effects. To assess these associations, investigators are increasingly using chemical mixture approaches like weighted quantile sum (WQS) regression. In these studies, the research objectives are to determine whether a mixture of correlated chemicals is associated with an adverse health outcome and to identify the important chemicals. However, as experimental equipment measures each exposure to a chemical-specific detection limit, the exposures are unknown between zero and the detection limit. Indeed, the number of exposures below …


Reducing Disparities In Smoking For Adults With Mental Illness: Are U.S. Tobacco Prevention Policies Effective?, L. Morgan Snell Jan 2020

Reducing Disparities In Smoking For Adults With Mental Illness: Are U.S. Tobacco Prevention Policies Effective?, L. Morgan Snell

Theses and Dissertations

One in five people in the U.S. are estimated to experience “any mental illness” (AMI); however this group represents an estimated 40% of the annual, adult cigarette consumption in the U.S. Tobacco prevention policies have been successful at reducing smoking prevalence among the U.S. population as a whole, however it is unclear whether these efforts have had significant impact on tobacco use rates among individuals with AMI. The three papers that comprise this project combined longitudinal, nationally-representative data and online behavioral experiments from U.S. adults to compare demand for cigarettes among adult smokers with and without AMI. Taken together, our …


Doctor-Patient Communication: The Experiences Of Black Caribbean Women Patients With Diabetes, Rosanne Paul-Bruno Jan 2020

Doctor-Patient Communication: The Experiences Of Black Caribbean Women Patients With Diabetes, Rosanne Paul-Bruno

Theses and Dissertations

This applied dissertation was designed to examine the verbal and non-verbal communication experiences of Black Caribbean diabetic women patients with their doctors, in order to provide a better understanding of the essential aspects of doctor- patient communication and their experiences as they managed their condition. Black Caribbean women have been disproportionately impacted by medical conditions such as diabetes. It has been a documented fact that minorities experience disparities in the health care system at different levels and doctor-patient communication is no exception. Poor doctor-patient communication has been known to hinder patients’ health outcomes, and therefore warrants such studies to increase …


“Is Therapy For Me?” Perceptions Of Therapy Inclusivity And Willingness To Seek Help Among Black Emerging Adults, Randl B. Dent Jan 2020

“Is Therapy For Me?” Perceptions Of Therapy Inclusivity And Willingness To Seek Help Among Black Emerging Adults, Randl B. Dent

Theses and Dissertations

Mental health issues are prevalent among Black emerging adults; however, they tend to underutilize mental healthcare services. The goals of the current study were to examine whether: (1) perceived therapy inclusivity would predict willingness to utilize mental healthcare services and (2) the relationship between perceived therapy inclusivity and willingness would be moderated by two indices of racial identity (i.e., centrality and private regard). Results provide evidence that greater perceptions of therapy inclusivity are associated with greater willingness to seek mental health services even after controlling for factors, such as gender, self-stigma, and previous mental healthcare utilization. Additionally, there was no …


Associations Between Stress, Racial Discrimination, And Cytokine Levels In Black Americans, Takia Williams Jan 2020

Associations Between Stress, Racial Discrimination, And Cytokine Levels In Black Americans, Takia Williams

Theses and Dissertations

Inflammation is a common pathophysiological pathway for a number of chronic diseases and is influenced by exposure to stress. Although there are racial disparities in health outcomes, relatively little is known about factors that may influence the inflammatory response in Black American individuals. This study examined whether racial discrimination and other forms of stress are associated with the balance of pro- and anti- inflammatory cytokines in Black American adults. Data from 22 participants were drawn from a larger study of Black American children (ages 5-12) and their primary caregivers drawn from low income neighborhoods in Richmond, Virginia. Caregivers reported demographics, …

A Theoretically-Based Mixed Methods Approach To Examining Mental Health Disorders And Help-Seeking Behaviors Among University-Enrolled African American Men, Kofoworola D.A. Williams Jan 2020

A Theoretically-Based Mixed Methods Approach To Examining Mental Health Disorders And Help-Seeking Behaviors Among University-Enrolled African American Men, Kofoworola D.A. Williams

Theses and Dissertations

Recent studies show that African American men in college are disproportionately experiencing high levels of psychological distress, increasing their risk of developing mental health symptoms associated with depression and anxiety. Despite being at higher risk for developing mental health symptoms, university-enrolled, African American men are not seeking help even when experiencing high levels of stress and anxiety, impacting their academic performance. The evidence base describing mental health symptom prevalence and evidence-based prevention strategies among university-enrolled, African American men is limited. To that end, this dissertation work utilized a concurrent, mixed methods approach, theoretically-based in the Social Ecological Model (SEM), to …

Pediatric asthma is a major public health concern that disproportionately affects children of color and youth living in low-income, urban areas. The implications for public health, child health, and family functioning necessitates our understanding and addressing experiences by families who are facing barriers within their socio-demographic context in addition to the stressors associated with managing pediatric asthma. The current study applied qualitative methods to interviews with caregivers of children with and without asthma in an effort to more deeply connect with caregivers’ experiences and yield richer information about the intersection of identities as Black caregivers living in an urban setting …


The Impact Of The Fda Warning On Post-Tonsillectomy Opioid Prescribing In Publicly And Privately Insured Children, Dianna J. Soelberg Jan 2020

The Impact Of The Fda Warning On Post-Tonsillectomy Opioid Prescribing In Publicly And Privately Insured Children, Dianna J. Soelberg

Theses and Dissertations

Due to reports of significant adverse events, the U.S. FDA placed a Boxed Warning on the opioid codeine in February 2013 – contraindicating its use in pediatric patients undergoing tonsillectomy and/or adenoidectomy. Studies conducted in privately insured children showed a reduction in codeine prescribing and a slight increase in alterative opioid prescribing following the FDA warning, yet the extent to which the FDA warning impacted prescribing in publicly insured children is unknown. Using a quasi-experimental interrupted time series design, this study evaluated codeine and alternative opioid prescribing before and after the FDA warning in both publicly and privately insured children …


Black Women And Body Image: Implications Of The Racialized Beauty Aesthetic, Rachel L. Boutte Jan 2020

Black Women And Body Image: Implications Of The Racialized Beauty Aesthetic, Rachel L. Boutte

Theses and Dissertations

Black women have the highest prevalence of overweight and obesity relative to any other demographic group in the United States, however current weight management interventions appear least effective for them. Although several hypotheses have been proposed to explain these outcomes, few studies have collected data to evaluate how well they fit the lived experiences of Black women. In particular, the potential roles of body image and body dissatisfaction in the development and maintenance of overweight and obesity in Black women are not well understood. Extant literature largely reports that Black women are inoculated from body dissatisfaction due to cultural factors, …

First diagnosed in the early 20th century, the disease has gone underdiagnosed and has attracted little attention for …


Dietary Advanced Glycation End-Products (Ages) And Breast Cancer Risk And Survival, Omonefe Opeyemi Omofuma Oct 2019

Dietary Advanced Glycation End-Products (Ages) And Breast Cancer Risk And Survival, Omonefe Opeyemi Omofuma

Theses and Dissertations

Introduction: Advanced glycation end-products (AGEs) are implicated in the pathogenesis of chronic diseases including cancer. AGEs are produced endogenously and are also consumed from foods. High amounts of AGEs are found in animal products and processed foods, and AGE formation is accelerated during cooking at high temperatures. Using data from the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial (PLCO), we assigned and quantified NƐ-carboxymethyl-lysine (CML)-AGE content in food and investigated the association between dietary AGE intake and breast cancer (BrCa) risk. We assessed whether the risk was modified by race/ethnicity, obesity status, fruit and vegetable intake, BrCa invasiveness …

Longitudinal Trajectories Of Depressive Symptoms Among Youth And Young Adults With Type 1 Diabetes: Predictors And Health Outcomes, Melanie Whitmire Sutherland

Theses and Dissertations

Type 1 diabetes (T1D) is one of the most frequently diagnosed chronic illnesses among youth, and has many long-term complications, including retinopathy, neuropathy, and cardiovascular disease. The risk of these complications may be reduced through maintaining glycemic control and one potential risk factor for failure to achieve optimal glycemic control is elevated depressive symptoms among youth and young adults (YYA) with T1D. YYA with T1D are at increased risk of depression, which has been associated with adverse outcomes such as poor adherence to self-management and poor glycemic control. Although a robust body of research exists on the association between comorbid …


The Intergenerational Effects Of Adverse Childhood Experiences On Children’S Emergency Department Utilization And Depression And Anxiety In South Carolina, Eboni E. Haynes Oct 2019

The Intergenerational Effects Of Adverse Childhood Experiences On Children’S Emergency Department Utilization And Depression And Anxiety In South Carolina, Eboni E. Haynes

Theses and Dissertations

Adult exposure to adverse childhood experiences (ACEs) is common in the U.S., with over half of adults reporting exposure to at least one ACE. Childhood trauma is associated with risk factors for premature death, disability, poor physical and mental health, and lower quality of life in adults. Traumatic experiences also influence parenting behaviors later in life, placing offspring at an increased risk of ACE exposure. Few studies have explored the intergenerational effects of ACEs on the health and well-being of offspring. This study sought to identify whether associations existed between caregiver ACE exposures and emergency department (ED) utilization for sick …

Did Medicaid Expansion Under The Affordable Care Act Reduce The Likelihood That People Report Employment Status Changes Due To Health, U.S., 2009-2017, Songyuan Deng

Theses and Dissertations

Medicaid expansion of Affordable Care Act (ACA) extended coverage to low-income working adults. While Medicaid expansion led to increased healthcare use and national healthcare expenditures, current studies do not examine the effects of Medicaid expansion on health status from the perspective of social roles, for example, changes in employment status. This study use data from the Current Population Survey to examine the association between Medicaid expansion and the probability to attribute part-time work or not-in-labor- force to health issues among people with family annual income no more than 138 of Federal Poverty Level, with a difference-in-differences study design. We found …


Clinically Integrated Networks: The ‘Magic Pill’ For Improving The Quality Of Health Care?, Kaitlyn Ann Crosby Oct 2019

Clinically Integrated Networks: The ‘Magic Pill’ For Improving The Quality Of Health Care?, Kaitlyn Ann Crosby

Theses and Dissertations

The Patient Protection and Affordable Care Act (ACA) served as a paradigm shift to reimburse physicians based on health outcomes or quality of care patients receive in relation to and conscious of the cost to provide care, rather than the traditional fee-for- service (FFS) system. To implement value-based care under the ACA, value-based care models (VBCM), such as patient-centered medical homes (PCMH) and accountable care organizations (ACO), were formed with the ultimate goal to advance quality of care. Among commercially insured populations, clinically integrated networks (CIN) have emerged as another type of VBCM.

Since CINs are the newest type of …

Hiv Care Location: An Evaluation Of Single Versus Multi Facility Utilization Of Hiv/Aids Care Services And Patient Health Outcomes And Clinical Indicators In South Carolina, Melanie Gwynn

Theses and Dissertations

Background: On the HIV/AIDS care continuum, the “retention in care” metric does not distinguish between single-facility (SF) or multi-clinic utilization (MC), also described as HIV care location (or type). SF utilization is vital as it has been linked optimal clinical outcomes among People Living with HIV/AIDS (PLWH). Published research detailing the prevalence of HIV care type and its association with health outcomes/clinical indicators, has been studied only in limited urban settings. Additionally, coinfections such as sexually transmitted infections (STIs), have yet to be evaluated as potential predictive factors for HIV care type.

Methods: A cross-sectional design was used …

Behavioral And Neural Correlates Of Aging Effects On Temporal Predictive Mechanisms During Speech Production And Limb Movement, Karim Joharikhatoonabad Jul 2019

Behavioral And Neural Correlates Of Aging Effects On Temporal Predictive Mechanisms During Speech Production And Limb Movement, Karim Joharikhatoonabad

Theses and Dissertations

Existing evidence suggests that the brain facilitates motor responses to temporally predictable sensory inputs by generating more robust predictions about the timing of incoming stimuli to better estimate the next state of movement. In this context, previous studies have shown that motor responses are generated with faster reaction time in response to sensory stimuli with predictable compared to those with unpredictable temporal dynamics. However, our understanding of the underlying behavioral and neural mechanisms of temporal predictive mechanisms during movement production has remained limited by several factors. First, studies regarding temporal predictive mechanisms have mainly examined limb movement as a target …
