Effect Of Total Body Iron On Metabolic Dysfunction Among U.S. Females In The Nhanes 2003-2010, Aged 12-49., Joseph Michael Carhart
Electronic Theses and Dissertations
Experimental and epidemiological studies have reported positive associations between iron parameters and metabolic dysfunction including: Type 2 diabetes mellitus (T2DM) (1-6), metabolic syndrome (7-15), non-alcoholic fatty liver disease (NAFLD) (16-22) and insulin resistance (23,24) with a number of studies showing that reductions in total body iron via dietary modification (e.g., reducing red meat intake) or phlebotomy lead to increases in insulin sensitivity (25), decreases in insulin resistance (26), and reductions in the prevalence of complications associated with T2DM (5, 27), metabolic syndrome (28) and NAFLD (22, 29). Moreover, the risk associated with these outcomes and total body iron differ between …

Moving Mountains : A Study Examining Long-Term Impacts Of Mountaintop Removal Coal Mining On Mortality In The Appalachian Region Using Geographic Information Sciences Techniques., James Howard Kent Pugh
Electronic Theses and Dissertations
Over the last hundred years, the Appalachian region has been dominated by the coal industry. It has also been and currently is one of the unhealthiest regions in the United States. Recent scholarship has examined the relationship between coal mining and health and mortality rates in the Appalachian region. The first study incorporates air quality and pollution data to examine if coal mining counties have higher levels of pollution and if this pollution contributes to mortality disadvantage. In the second study, I construct a population-based coal-exposure measure to better evaluate the relationship between coal mining and health I find that …
Prospective Studies Of Cardiovascular Risk Factors And Mild Cognitive Impairment, Kevin Sullivan
Prospective Studies Of Cardiovascular Risk Factors And Mild Cognitive Impairment, Kevin Sullivan
Electronic Theses and Dissertations
The association of cardiovascular risk factors including hypertension, diabetes, cholesterol, kidney function, and arterial stiffness with cognitive impairment in older adults is a well-studied phenomenon. However, there is considerably less evidence relating cardiovascular health specifically to a diagnosis of Mild Cognitive Impairment (MCI). As a precursor state of dementia, MCI is characterized by a decline in cognitive function from previous level, but not to the degree that activities of daily living are impaired. Not everyone who is diagnosed with MCI will eventually transition to dementia, but the transition rates are much higher compared to the general population (5-15% per year …

The Increasing Risk Of Vector-Borne Diseases: Mapping The Effects Of Climate Change And Human Population Density On Future Aedes Aegypti Habitats, Julie Obenauer
Electronic Theses and Dissertations
The Aedes aegypti mosquito is the vector for four infectious diseases of global concern – Yellow Fever, Dengue, Chikungunya, and Zikavirus. Previous attempts to model the expansion of the vector habitat due to global climate change have rarely included characteristics related to the human populations on which this mosquito is dependent. The purpose of this research was to determine whether the inclusion of human population density improves model performance while creating risk maps that can be used to determine where humans are most likely to be exposed to the vector in the future. The resulting model demonstrated that the inclusion …

Prenatal Depression Screening Among A Diverse Healthy Start Population., Evangeline Pierce
Electronic Theses and Dissertations
Prenatal depression has been associated with adverse outcomes for both pregnant women and infants. Data was studied from Healthy Start (n=1093). Healthy Start participants were screened for depression using the Edinburgh Postnatal Depression Scale (EPDS) during pregnancy. Data reported included birthweight, gestational length, ethnicity, and sociodemographic variables. No statistically significant association was found between a positive EPDS screen and birthweight-low/normal (OR 1.02 [95% CI 0.53, 1.70]), birthweight-abnormal (OR 1.02 [95% CI 0.53, 1.70], or gestation-preterm/term (OR 1.29 [95% CI 0.68, 2.45]). An association was observed between a positive screen and race, ethnicity by region of origin, immigrant status, English as …
The Effect Of Caffeine On Fecundability : Differences In Coffee, Tea, And Cola Consumption., Emily Kathleen Steinmetz
The Effect Of Caffeine On Fecundability : Differences In Coffee, Tea, And Cola Consumption., Emily Kathleen Steinmetz
Electronic Theses and Dissertations
This study examined whether intake of caffeinated beverages (coffee, tea, and cola) was associated with fecundability (time to pregnancy) in a prospective cohort study. Data from 470 women from the Mount Sinai Study of Women Office Workers (1990-1994) were analyzed. Intake of coffee, tea, cola, and other variables were recorded in daily diaries and calculated as menstrual cycle level means for up to 20 cycles. Pregnancy was assayed using hCG and confirmed by physician diagnosis. The associations of caffeinated beverages with the probability of becoming pregnant during a given cycle were determined using discrete survival analysis, adjusted for potential confounders. …
The Particulars About Particulates : Metal Exposure And Self-Regulation Of Children Living Near Coal Ash., Clara G. Sears
The Particulars About Particulates : Metal Exposure And Self-Regulation Of Children Living Near Coal Ash., Clara G. Sears
Electronic Theses and Dissertations
The use of coal combustion for electricity and the storage of coal combustion by-products known as coal ash occur across the United States and around the world. The most abundant type of coal ash, fly ash, contains small particles with metals, some of which are known neurotoxins. Fly ash is currently stored in open-air landfills and surface impoundments that allow fugitive dust to escape into surrounding communities, potentially exposing children to small neurotoxic particles. This dissertation uses preliminary data from a larger cross-sectional study to investigate the relationship between particulate matter exposure, metal exposure, and problems with self-regulation. Recruitment of …
Pediatric Anxiety And/Or Depression Problems : Associations With Pm10, Fly Ash, And Metal Exposure., Abby Nicole Burns Hagemeyer
Pediatric Anxiety And/Or Depression Problems : Associations With Pm10, Fly Ash, And Metal Exposure., Abby Nicole Burns Hagemeyer
Electronic Theses and Dissertations
Background: In the last several decades, the use of coal has become more prevalent in turn increasing the amount of coal ash being produced. Coal ash, the by-product of coal combustion, is composed of small particles that contain essential elements, hazardous metals, polycyclic aromatic hydrocarbons, and radioactive material. While a small proportion of coal ash is reused, the majority gets discarded in open-air landfills and ash ponds. Fly ash, the major component of coal ash, can become emitted into the air and potentially contribute to the air pollution and metal exposure in the surrounding community. Few studies, particularly in the …

Correlates Of Human Papillomavirus (Hpv) Vaccine Acceptance In Appalachian Tennessee, Oluwatosin Ariyo
Electronic Theses and Dissertations
Human papillomavirus (HPV) is the most prevalent sexually transmitted infection in the U.S., where one HPV-related cancer is diagnosed every 20 minutes. The most common HPV-related cancer is cervical cancer, with an estimated incidence of 12,000 cases annually, a third of which lead to death. Cervical cancer disparately affects women of ethnic minority groups and geographically isolated regions, such as Appalachia. Tennessee ranks third highest in cervical cancer incidence in the country. Many cases of cervical cancer could be prevented through vaccination against HPV, however, vaccination rates for females in Tennessee are among the lowest in the country. This mixed-methods …

Exploring Job Satisfaction And Preceptorship Capacity Among Applied Epidemiologists, Jessica C. Arrazola
Electronic Theses and Dissertations
Job satisfaction is important to consider when developing strategies for recruitment and retention. The Public Health Workforce Interests and Needs Survey (PH WINS) conducted in 2014 was the first nationally representative assessment of the state public health workforce. Prior to this assessment, the job satisfaction of state agency public health workers and preceptor capacity had not been measured. This study fills the current research gaps by studying the job satisfaction among the applied epidemiology workforce, identifying factors influencing job satisfaction, and the describing the preceptorship capacity among epidemiologists. This research is based on the 2014 PH WINS data. The analysis …
Application Of The Misclassification Simulation Extrapolation (Mc-Simex) Procedure To Log-Logistic Accelerated Failure Time (Aft) Models In Survival Analysis, Varadan Sevilimedu
Application Of The Misclassification Simulation Extrapolation (Mc-Simex) Procedure To Log-Logistic Accelerated Failure Time (Aft) Models In Survival Analysis, Varadan Sevilimedu
Electronic Theses and Dissertations
Survival analysis is the study of time to event outcomes. Accelerated Failure Time models (AFT) serve as a useful tool in survival analysis to study the time of occurrence of an event and its relation to the covariates of interest. The accuracy of estimation of parameters in a model depends upon the correct measurement of covariates. Considering that perfect measurement of covariates is highly unlikely, it is imperative that the performance of the existing bias-correction methods be analyzed in AFT models. However, certain areas of bias-correction in AFT models still remain unexplored. One of these unexplored areas, is a situation …
