The purpose of this research was to assess collegiate athletes using hourly food and exercise data to examine how protein timing and energy balance relate to body composition. Aims 1 and 2 focus on collegiate female soccer athletes and further our understanding of the potential roles that protein amount and frequency and hourly energy balance play in optimizing fat mass and fat-free mass. …


The Mechanism Of Glucose-Induced Trib3 Expression In Myoblasts And Myotubes, Xiaobing Liu Jan 2019

The Mechanism Of Glucose-Induced Trib3 Expression In Myoblasts And Myotubes, Xiaobing Liu

All ETDs from UAB

Our previous data indicates that glucose-toxicity is dependent upon upregulation of TRIB3 expression in muscle. TRIB3 is a glucose-responsive gene and, as a pseudokinase, it blocks phosphorylation of AKT resulting in insulin resistance. The purpose of the current study was to identify the role of the differentiation process and the minimal functional sequence of TRIB3 promoter region in modulating glucose-induced TRIB3 gene expression in C2C12 myocytes. First, C2C12 myocytes were collected every 48 hours during the whole differentiation, totally 4 intervals. Before collection, cells were treated with either 5mmol glucose or 25mmol glucose for 24 hours. Under 5mmol glucose, the …


Insuring Graduation: An Analysis Of The Association Between Student Health Insurance And Graduation, John Robert Lovett Jan 2019

Insuring Graduation: An Analysis Of The Association Between Student Health Insurance And Graduation, John Robert Lovett

All ETDs from UAB

Most college students have access to basic health services through their campus’ college health program. Unfortunately, students who lack health insurance may be limited in their access to health services beyond the acute care provided, which may manifest in a myriad of adverse outcomes; ultimately resulting in withdrawal from college without graduating. Student health insurance plans (SHIPs) are high-quality, affordable insurance plans specially designed to meet this need. This study utilized survival analysis to examine the temporal nature of college graduation behavior, as it related to student health insurance status. The results of this study show no significant relationship between …

Obesity In People With Spinal Cord Injury: Secondary Data Analysis Of National Spinal Cord Injury Database, Huacong Wen

All ETDs from UAB

People with disabilities are 1.5-2.5 times more likely to be obese than those without disabling conditions. We have learned a lot about obesity in the general population. However, the neurological deficits of people with spinal cord injury (SCI) make it difficult to generalize the findings in the general population to the SCI population. Therefore, the purposes of this dissertation were to 1) assess racial differences in body mass index (BMI) change over 5 years; 2) evaluate the role of neighborhood in the relationship between race and obesity; 3) examine the impact of BMI at the time of injury on 1-year …


Postpartum Body Composition And Breast Milk Hormones, Camille Schneider Jan 2019

Postpartum Body Composition And Breast Milk Hormones, Camille Schneider

All ETDs from UAB

The prevalence of both adult and child obesity continues to rise. Children born to mothers with obesity have a greater risk for future obesity and chronic disease. There is an increasing body of literature suggesting that pregnancy and infancy are critical periods influencing the child’s risk for obesity. However, little is known about whether consumption of breast milk from an obese mother might influence the child’s metabolic programming and growth. The purpose of this dissertation was to examine the association of maternal adiposity with insulin and leptin in breast milk and, in turn, whether breast milk insulin, leptin, and glucose …


Using Behavioral Health Data From A Health Information Exchange: An Examination Of Facilitators And Barriers, Randyl Cochran Jan 2019

Using Behavioral Health Data From A Health Information Exchange: An Examination Of Facilitators And Barriers, Randyl Cochran

All ETDs from UAB

Behavioral health disorders are common, and they frequently co-occur with chronic physical illnesses. Behavioral health patients with chronic physical illnesses are three times more likely to be readmitted to the hospital within 30 days of discharge than non-behavioral health patients. Readmissions among behavioral health patients are costly: $817 million in readmissions costs are related to mood and psychiatric disorders. High readmission rates are attributed, in part, to poor exchange of health-related information between various care providers. Health information exchanges (HIEs) are effective in chronic disease management, but their effectiveness in integrated care delivery is unclear. This study examined facilitators of …


Effects Of Differential Fore Aft Resistance On Propulsive Force Generation During Walking In Nonimpaired And Poststroke Individuals, Avantika Naidu Jan 2019

Effects Of Differential Fore Aft Resistance On Propulsive Force Generation During Walking In Nonimpaired And Poststroke Individuals, Avantika Naidu

All ETDs from UAB

Background: Impaired paretic limb-loading dynamics and force-generation ability due to hemiparesis are partially responsible for permanent locomotor deficits poststroke. During walking, inability of the paretic limb to generate sufficient propulsive-forces causes reliance on compensatory strategies, wherein the nonparetic limb generates the majority of propulsive-forces needed for forward progression and speed modulation. Purpose: To investigate factors that can improve paretic limb propulsion and walking function, I present four studies. The first pertains to a protocol for a poststroke body-weight-support treadmill-training (BWSTT) study, while the others concern a mechanistic exploration of propulsive-force generation during walking against combined and differential FA resistance. Methods: …


Physical Activity Promotion Among Adolescents With Pediatric Onset Multiple Sclerosis, Elizabeth Morghen Sikes Jan 2019

Physical Activity Promotion Among Adolescents With Pediatric Onset Multiple Sclerosis, Elizabeth Morghen Sikes

All ETDs from UAB

Pediatric onset multiple sclerosis (MS) is a chronic and disabling disease of the central nervous system with an onset before 18 years of age. Youth with pediatric onset MS may benefit from physical activity as evidenced by past research suggestsing higher levels of physical activity are associated with reduced physical and psychosocial disease manifestations. Unfortunately, published estimates of physical activity participation among those with pediatric onset MS are very low (<10 min/day). This dissertation aimed to describe the current literature regarding physical activity among youth with pediatric MS, and to further explore experiences, patterns, correlates, and potential confounders of physical activity for the ultimate purpose of informing future behavior change interventions. Results are presented through five single study chapters. Briefly, interventions developed to promote physical activity for adolescents with pediatric onset MS should be individually tailored, include a strong social component, aim to educate regarding safety and outcomes of physical activity, and differentially target weekday and weekend day activity and sedentary behavior. Social cognitive theory (SCT) is an appropriate method for promoting physical activity behavior change among youth with pediatric onset MS, and SCT constructs including exercise goal setting, barriers self-efficacy, outcome expectations, and social support should be incorporated in the intervention as appropriate. Further, physical activity is seemingly an appropriate method for the management of functional limitations for youth with pediatric onset MS. Clinicians and researchers seeking to promote physical activity among those with pediatric onset MS may find this dissertation especially useful in providing a framework for the development of behavior change interventions.

Reported Clinical And Financial Performance Of Hospitals With Physician Ceos Compared To Those With Nonphysician Ceos, Leon Moores

All ETDs from UAB

Leaders impact organizational behavior and performance, and CEOs may have greater impact via numerous proposed mechanisms. Because of this, organizations expend considerable resources recruiting and selecting CEOs and may benefit from information suggesting a positive impact on organizational performance based upon measurable CEO characteristics. Little work has been done comparing the performance of hospitals with physician CEOs versus non-physician CEOs, in spite of the ease of identification of this characteristic and extant leadership theories suggesting a relationship between technical expertise and success in leading highly technical organizations. We compared multiple measures of reported clinical and financial performance and our linear …


A Crisis In Care: Evaluating The Causes And Consequences Of Burnout Among Emergency Physicians, Michael Allyn Wiechart Jan 2019

A Crisis In Care: Evaluating The Causes And Consequences Of Burnout Among Emergency Physicians, Michael Allyn Wiechart

All ETDs from UAB

For many physicians, the growing list of mandates and the unrelenting pace of change in today’s health care have taken a toll, leading to burnout. The consequences of burnout extend well beyond the impact on the individual provider, with physician burnout linked to a decrease in patient satisfaction, an increase in preventable medical errors, and increased levels of staff turnover. Consequently, the high rates of burnout reported among U.S. physicians might be considered not only as a symptom of dysfunction in the health care delivery system but also as a factor contributing to the dysfunction. While burnout exists to a …


Provider-Sponsored Health Plans In The Post-Reform Era, Katherine Ann Meese Jan 2019

Provider-Sponsored Health Plans In The Post-Reform Era, Katherine Ann Meese

All ETDs from UAB

The rise and fall of managed care in the 1980s and 1990s saw many hospitals and health systems in the United States enter and subsequently exit the health insurance market in the form of provider-sponsored health plans (PSHP). The passage and implementation of the legislation such as the Patient Protection and Affordable Care Act (ACA) and the Medicare Access and CHIP Reauthorization Act (MACRA) has ushered in an era of value-based reimbursement methods and a heightened focus on population health management, which has stimulated health care organizations to contemplate health plan ownership as a logical strategy. This study examined market …

Significance Of Acculturation, Assimilation, And Allostatic Load As Risk Factors For Obesity Among Hispanics, Yenni Elvia Cedillo

All ETDs from UAB

Obesity has increased during the last two decades in the United States (U.S.) and is considered a major risk factor for chronic diseases within the Hispanic community. The burden of obesity in Hispanics is associated with higher rates of morbidity and mortality and an increase in healthcare costs. Hispanics’ challenges after migration extend to subsequent generations, putting the population at risk for disease development. Specifically, migration can lead to the adoption of health behaviors, beliefs, values, and language of the host country, a process known as acculturation, which has been associated with changes in health behaviors. Among the Hispanic population, …
