Examining The Influence Of Healthy Eating Identity On Shopping Behaviors, Jordan Brittingham
Examining The Influence Of Healthy Eating Identity On Shopping Behaviors, Jordan Brittingham
Theses and Dissertations
Eating identity is shown to be a promising measure capable of enhancing our understanding of nutrition behavior. Persons with healthy eating identities are less likely to consume the typical American diet and report healthier diets in general. While there are several studies linking healthy eating identity and diet, there is currently no research examining healthy eating identity in relation to food shopping behavior, an important aspect of nutritional intake. The purpose of this study was to examine the influence of healthy eating identity on shopping behaviors including supermarket utilization, supercenter utilization, likelihood of shopping at the nearest store, distance to …
Periodontal Microorganisms, Obesity, Chronic Inflammation, And Type 1 Diabetes, Georges Joseph Nahhas
Periodontal Microorganisms, Obesity, Chronic Inflammation, And Type 1 Diabetes, Georges Joseph Nahhas
Theses and Dissertations
Periodontal disease is a low-grade chronic inflammation in the tissues surrounding the teeth caused by multiple, mostly gram-negative pathogens. It is associated with diabetes, obesity, and chronic inflammation. The specific roles that periodontal microorganism play in these conditions are not well-studied. Hereby, we explored how periodontal bacteria from sub gingival plaque clustered in youth with and without type 1 diabetes, and how such patterns related to body-mass-index percentile (BMI percentile), C-reactive protein (CRP) and adiponectin. Cross-sectional data were collected from 105 youth with type 1 diabetes and 71 without diabetes. Participants were between 12 and 19 years of age receiving …
Effect Of Primary Care Physician Density On Late Stage Cervical Cancer Diagnosis, Emily Haanschoten
Effect Of Primary Care Physician Density On Late Stage Cervical Cancer Diagnosis, Emily Haanschoten
Theses and Dissertations
INTRODUCTION: Late-stage cervical cancer diagnosis is an important contributing factor to the cervical cancer mortality rate. Screening for cervical cancer is a vital tool in reducing the number of late-stage cases, preventing incident cases and reducing mortality. Access to care is often a significant barrier to receiving these services. Women who have no usual source of care report significantly lower percentages of Pap tests than women who have a usual source. South Carolina ranks 13th in the US in cervical cancer incidence and 7th in cervical cancer mortality. South Carolina also struggles with a primary care physician shortage, ranking 39th …
Single Nucleotide Polymorphisms In Dna Repair And Oxidative Stress Genes, And Their Interaction With Antioxidants On Prostate Cancer Aggressiveness, Samuel Antwi
Theses and Dissertations
Prostate cancer is the leading invasive malignancy and the second most common cause of cancer death among American men. Despite compelling evidence that oxidative stress, ineffective DNA damage repair, and habitually low antioxidants intake may act in tandem to influence prostate carcinogenesis, few studies have examined gene-diet interactions involving these risk factors. Even fewer studies have examined such interactions in relation to prostate cancer aggressiveness. This study investigated whether single nucleotide polymorphisms (SNPs) in DNA repair- and oxidative stress-related genes modulated associations between antioxidant intake and prostate cancer aggressiveness. We utilized data from the North Carolina-Louisiana Prostate Cancer Project (PCaP) …

Theses and Dissertations
Alzheimer’s disease (AD) is a neurological disorder that affects elderly individuals, and is becoming an increasing concern among the aging population of the world. Due to the projected increase in incidence of AD, modifiable risk factors such as depression and obesity should be evaluated, as prevention is the only current option. This study aimed to determine the prevalence of obesity and depression among AD patients, and to evaluate the association between depression and obesity. Patients were chosen from a subset of the South Carolina Alzheimer’s disease registry, which included information about weight status and depression, as well as several other …
Assessing The Structural Validity Of The Measure Of Processes Of Care (Mpoc-20) In Children With Epilepsy, Kariym Christopher Joachim
Assessing The Structural Validity Of The Measure Of Processes Of Care (Mpoc-20) In Children With Epilepsy, Kariym Christopher Joachim
Electronic Thesis and Dissertation Repository
The goal of this thesis was to determine whether the 20-item Measure of Processes of Care (MPOC-20) questionnaire remains structurally/factorially valid among children with epilepsy, and to propose adaptations if it did not. Establishing the MPOC-20’s structural validity in this population makes it possible to draw conclusions on the potential effects of parent-perceived Family-Centred Care (FCC) on health outcomes within this population. Data came from the Health-related Quality of Life for Children with Epilepsy Study (HERQULES). Confirmatory Factor Analysis (CFA) indicated that the original five factor model fit poorly in children with epilepsy. An exploratory analysis within a CFA framework …

Utilizing Landsat Tm And Oli In Predicting Oncomelania Hupensis Habitats Around Poyang Lake Before And After Three Gorges Dam Completion, Stephanie L. Mccracken
Honors Theses
Schistosomiasis is a parasitic disease caused by the Schistomsoma japonicum flatworm that utilizes the Oncomelania hupensis snail as an intermediate agent. In the People’s Republic of China, these amphibious snails contaminate freshwater systems infecting humans, bovines, and other mammals and have caused significant morbidity for over two thousand years (Wertheim, et al. 2012; Zhang, et al. 2012.) The gravity of this disease prompted the national government to initiate sizable public health programs, such as the World Bank Loan Project (WBLP.) In spite of WBLP's achievements, in 2004, after this program ended, a national survey acknowledged a resurgence of schistosomiasis in …
Assessing The Social And Ecological Factors That Influence Childhood Overweight And Obesity, Katie Callahan
Assessing The Social And Ecological Factors That Influence Childhood Overweight And Obesity, Katie Callahan
Electronic Theses and Dissertations
The prevalence of childhood overweight and obesity is increasing at an alarming rate in the United States. Currently more than 1 in 3 children aged 2-19 are overweight or obese. This is of major concern because childhood overweight and obesity leads to chronic conditions such as type II diabetes and tracks into adulthood, where more severe adverse health outcomes arise. In this study I used the premise of the social ecological model (SEM) to analyze the common levels that a child is exposed to daily; the intrapersonal level, the interpersonal level, the school level, and the community level to better …
Factors Associated With Rapid Readmission Among Nevada State Pyschiatric Hospital Patients, Christopher Owen Moore
Factors Associated With Rapid Readmission Among Nevada State Pyschiatric Hospital Patients, Christopher Owen Moore
UNLV Theses, Dissertations, Professional Papers, and Capstones
Rapid readmission (RR) of psychiatric patients within 30 days of discharge places a costly burden on state psychiatric facilities and may be an indicator of suboptimal service provision. Several studies have previously considered RR to inpatient facilities, but there is a lack of information available about the variables associated with RR of psychiatric patients to state-operated inpatient facilities in Nevada. This study attempts to identify factors associated with RR at a southern Nevada state psychiatric hospital. Participants included 7,177 patients admitted between May 1, 2012 and April 30, 2014. All 12,068 admissions, including 2,220 RR, were reviewed, and rapid readmits …

Quality of life studies in Duchenne Muscular Dystrophy are scarce. This study explores the relationship between the broad concept of quality of life and the more focused concept of health-related quality of life and examines the relationships between patient and family characteristics and health-related quality of life. Participants were recruited from the Canadian Neuromuscular Disease Registry, 98 parents and 85 children completed the Quality of My Life and Pediatric Quality of Life Inventory questionnaires. Simple regression was used to examine the relationship between quality of life and health-related quality of life. Multivariable linear regressions were used to determine child and …
Stress And Depression During Pregnancy Among Hispanic Women: Risk For Adverse Birth Outcomes And The Role Of Physical Activity, Kathleen Szegda
Stress And Depression During Pregnancy Among Hispanic Women: Risk For Adverse Birth Outcomes And The Role Of Physical Activity, Kathleen Szegda
Doctoral Dissertations
Preterm birth and low birth weight are among the leading causes of infant mortality and morbidity in the United States. Puerto Rican women are at increased risk for these adverse birth outcomes and elevated levels of depression and psychosocial stress during pregnancy when compared to non-Hispanic Whites. Therefore, it is important to understand whether these psychological factors increase risk for these adverse birth outcomes and mechanisms to prevent/reduce depression in this high-risk population. The first study of this dissertation examined associations between perceived stress during pregnancy and preterm birth, low birth weight, and birth of a small-for-gestational age infant (SGA) …
Nutritional, Hormonal, And Psychological Risk Factors For Breast Cancer, Susan Nicole Boyer Brown
Nutritional, Hormonal, And Psychological Risk Factors For Breast Cancer, Susan Nicole Boyer Brown
Doctoral Dissertations
Over the course of a lifetime, one in eight women will develop breast cancer. To date, 30-40% of breast cancer cases can be attributed to established risk factors, which supports the need for identification of additional modifiable risk factors. Therefore, we conducted three epidemiologic studies to examine the associations between nutritional, hormonal, and psychological risk factors and breast cancer risk. In our first study, we examined the relationship between urinary melatonin levels and the risk of breast cancer in a nested-case control study within the Nurses’ Health Study II. While limited in some respects, experimental and epidemiologic evidence support the …

Statistical Analysis And Modeling Of Pm2.5 Speciation Metals And Their Mixtures, Boubakari Ibrahimou
USF Tampa Graduate Theses and Dissertations
Exposure to fine particulate matter (PM2.5) in the ambient air is associated with various health effects. There is increasing evidence which implicates the central role played by specific chemical components such as heavy metals of PM2.5. Given the fact that humans are exposed to complex mixtures of environmental pollutants such as PM2.5, research efforts are intensifying to study the mixtures composition and the emission sources of ambient PM, and the exposure-related health effects. Factor analysis as well source apportionment models are statistical tools potentially useful for characterizing mixtures in PM2.5. However, classic …
The Association Between Urinary Bisphenol-A, Phthalate Metabolites And Body Fat Composition In Us Adults Using Nhanes, Iris E. Corbasson
The Association Between Urinary Bisphenol-A, Phthalate Metabolites And Body Fat Composition In Us Adults Using Nhanes, Iris E. Corbasson
Masters Theses
Due to the widespread use of the endocrine disruptors Bisphenol-A (BPA) and phthalates in many plastic consumer goods, medical equipment, and personal care products, more than 95% of the US population show detectable levels of urinary BPA and phthalate metabolites. Both have been linked to increased body mass index (BMI in kg/m2), an inexpensive diagnostic tool for obesity, which may however not reflect body fatness. Since excess body fat is associated with cardiovascular diseases, cancer and type II diabetes, it is important to understand the relationship between body fat composition and exposure to BPA and phthalates, a relationship …
The Role Of Sleep Timing On Diet Quality And Physical Activity Among College-Aged Women Participating In The University Of Massachusetts Vitamin D Status Study, Deniz Azarmanesh
The Role Of Sleep Timing On Diet Quality And Physical Activity Among College-Aged Women Participating In The University Of Massachusetts Vitamin D Status Study, Deniz Azarmanesh
Masters Theses
Overweight and obesity are risk factors for various chronic diseases. Sleep has been associated with overweight and obesity. One potential mechanism by which sleep may lead to overweight and obesity is through positive energy balance (i.e. energy intake exceeding expenditure). There are few studies examining the impact of sleep timing (onset and wake time) on diet and exercise. In a cross sectional study, we examined associations between sleep timing and diet quality, and in separate models, between sleep timing and meeting the 2008 Physical Activity Guidelines for Americans among the participants of the UMass Vitamin D Status Study. A total …

Body Mass Index Trajectories: The Effect Of Fetal Size And Early Life Modifiable Factors, Mathew Roy
Electronic Thesis and Dissertation Repository
Background: This study examined the relationship between small for gestational age (SGA) status at birth, a measure of fetal growth restriction, and childhood body mass index trajectories (BMI) using data from the National Longitudinal Survey of Children and Youth. Analytic Method: Using latent growth curve modeling, the growth trajectories of a cohort of small and appropriate for gestational age singletons were modeled from 2-10 years (N=1,273 at baseline). Results: SGA status had no effect on the growth trajectories of children after adjusting for prenatal and early life sociodemographic and maternal variables, and also early life modifiable factors. Moreover, the modifiable …
Psychosocial Factors Affecting Pregnant Hispanic Women, Marushka L. Silveira
Psychosocial Factors Affecting Pregnant Hispanic Women, Marushka L. Silveira
Doctoral Dissertations
Prenatal psychosocial stress, anxiety, and depression are common, with higher rates among Hispanic women. While evidence supports an adverse effect of psychosocial factors on glucose intolerance and oral health, studies during pregnancy are sparse, particularly among Hispanic women. Therefore, we examined correlates of psychosocial factors and their associations with glucose intolerance and oral health among pregnant women. The first project examined correlates of high stress among 1,426 pregnant Hispanic participants in Proyecto Buena Salud, a prospective cohort study. Cohen’s Perceived Stress Scale was administered in early, mid- and late pregnancy. Using multivariable logistic regression, we found that increasing age, pre-pregnancy …

Maternal Employment During Infancy And Toddlerhood: Mechanisms For Associations With Childhood Overweight/Obesity In Canada, Nathalie Victoria Metzer
Maternal Employment During Infancy And Toddlerhood: Mechanisms For Associations With Childhood Overweight/Obesity In Canada, Nathalie Victoria Metzer
Electronic Thesis and Dissertation Repository
Background: Childhood overweight and obesity is a major public health issue, with approximately 1 in 3 children classified as overweight or obese in Canada. Research suggests that maternal employment during childhood may be associated with later overweight and obesity risk, but it is not known whether employment during infancy and toddlerhood has a similar effect on weight status. Mechanisms such as reduced breastfeeding and use of informal child care have been proposed in the literature but not been formally tested among infants and toddlers. It is important to identify possible mechanisms that could explain the association with overweight and obesity …
Access To The Local Aids Service Organization Among African, Caribbean And Other Black Residents Of Middlesex-London, Ontario, Canada, Soraya Blot
Electronic Thesis and Dissertation Repository
The migration of people from HIV-endemic countries has altered the demographics of the HIV epidemic in high-income countries. In Canada, most people from HIV-endemic countries are of African descent. While they are an established priority group for HIV-related services, they can face access difficulties. This study uses quantitative data from the Black, African and Caribbean Canadian Health Study to evaluate AIDS service organization access in Middlesex-London, Ontario, using the Andersen-Gelberg model for vulnerable populations and an overarching intersectionality framework. In bivariate analysis, older age, having a primary care provider, less inappropriate fear of contagion and less time in Canada were …
The Influence Of Religion On Attitudes Toward Alcohol Use In Jewish Adolescents, Toby R. Levin
The Influence Of Religion On Attitudes Toward Alcohol Use In Jewish Adolescents, Toby R. Levin
Walden Dissertations and Doctoral Studies
Historically, the Jewish faith has used alcohol in rituals and religious holidays in which adolescents are permitted to fully participate and this exposure to alcohol may influence attitudes and beliefs about underage drinking among Jewish adolescents. The purpose of this study was to determine if there was a relationship between the Jewish religion and attitudes toward alcohol among Jewish adolescents. The theoretical frameworks, on which this study was based, were the social bond theory and the social development theory. Each of these theories indicates that community is important to the individual. Using a cross sectional study design, 160 adolescents participated …
Gpu-Accelerated Influenza Simulations For Operational Modeling, Peter Holvenstot
Gpu-Accelerated Influenza Simulations For Operational Modeling, Peter Holvenstot
Masters Theses
Simulations of influenza spread are useful for decision-making during public-health emergencies. Policy-makers use models to predict disease spread and estimate the effects of various intervention strategies. Effective modeling of targeted intervention strategies requires accurate modeling of individual-level behavior and transmission. However, this greatly increases the computational costs of these agent-based models. In addition, if the models are used as an outbreak progresses, some operational decisions must occur rapidly in order to contain the spread of the disease.
Graphics Processing Units (GPUs) are a type of specialized processor used to drive graphical displays. Many recent devices also allow users to write …
Novel Serum Biomarkers For Lung Cancer Early Diagnosis And Clinical Outcome, Fanmao Zhang
Novel Serum Biomarkers For Lung Cancer Early Diagnosis And Clinical Outcome, Fanmao Zhang
Dissertations & Theses (Open Access)
The five-year survival rate for all stages of lung cancer combined is only 17%, which has changed little over the past 40 years. Despite the tremendous efforts made, serum biomarkers with clinical utility for lung cancer early detection and clinical outcome prediction are still lacking. Metabolic alterations have been recognized as an emerging hallmark of cancer. We aimed to investigate the metabolic changes associated with lung cancer and to identify novel clinically applicable serum biomarkers for lung cancer early diagnosis and clinical outcome.
Serum metabolites are potential biomarkers for lung cancer early detection. We first performed global metabolomic profiling followed …
