Electronic Theses and Dissertations

Objectives: the objective of this study is to estimate the impact of biological, psychosocial and other risk factors on stroke in African Americans enrolled in the JHS and determine the population attributable risk of risk factors. Methods: this study used a nested case control design. Cases were patients with stroke during the follow up period. Corresponding controls were selected from subjects who are alive at that time period and who are at risk of stroke by matching on the person-years spent in the cohort. Odds ratios (OR) and population attributable risks (PAR) were calculated to understand the association of risk …


Differences In Treatment-Seeking And Treatment-Adherence Factors For Tuberculosis In Armenian Versus Non-Armenian Populations Of Los Angeles County, Tanya Marie Ferguson 2016 Walden University

Differences In Treatment-Seeking And Treatment-Adherence Factors For Tuberculosis In Armenian Versus Non-Armenian Populations Of Los Angeles County, Tanya Marie Ferguson

Walden Dissertations and Doctoral Studies

Tuberculosis (TB) is a deadly, yet curable, infectious disease that continues to be a global health threat. Armenia suffers from rising TB incidence and mortality rates. Armenians living in Los Angeles (LA) County, where TB incidence is higher than national averages, is the second largest Armenian community in the world; therefore implications are that many TB cases are attributed to this group. Using the social ecological model as a theoretical framework, this concurrent, mixed-methods study compared Armenians to non-Armenians in LA County about their knowledge of TB and perceived barriers to seeking and adhering to treatment. Bivariate chi-square analysis from …

This study examined the prevalence of dental caries and periodontal disease and the relationships between oral health status and the oral health knowledge, attitudes, and practices of jail inmates housed in a large metropolitan jail located in the midwestern United States. This cross-sectional study collected data from 100 inmates using a 21-item closed-ended questionnaire in addition to oral examinations conducted by the jail's dentist to determine the extent of dental caries and periodontal disease …


Poverty, Food Insecurity, And Obesity Among Urban And Rural Populations, Tameka Ivory Walls 2016 Walden University

Poverty, Food Insecurity, And Obesity Among Urban And Rural Populations, Tameka Ivory Walls

Walden Dissertations and Doctoral Studies

Over 17 million food-insecure households are associated with increasing obesity rates across the United States. Although food insecurity and obesity are distinct social concerns, the two are linked and may be influenced by poverty and geographic location. Public health authorities and state leaders responsible for the health and nutrition of rural populations in particular would benefit from this information. The purpose of this quantitative cross-sectional study was to examine whether poverty mediated the relationship between food insecurity and obesity among urban and rural adults. The study was guided by the poverty, food insecurity, and obesity conceptual framework. The study addressed …


The Association Of Smoking With Low Back Pain In Adult Americans: Analysis Of The 2012 National Health Interview Survey, Bart Green 2016 Walden University

The Association Of Smoking With Low Back Pain In Adult Americans: Analysis Of The 2012 National Health Interview Survey, Bart Green

Walden Dissertations and Doctoral Studies

Back pain is a chronic disease epidemic and the most common chronic painful condition in Americans. It is associated with human suffering and enormous financial and social burdens. Smoking is a prevalent and harmful health behavior and is the greatest modifiable risk factor for many chronic diseases. Cigarette smoking is associated with back pain, but there is little research on this relationship among adults in the United States. Using biopsychosocial theory, this study examined (a) the prevalence of back pain (dependent variable) among smokers, former smokers, and never smokers (independent variable), and (b) the influence of age, sex, race, body …


Methylmercury Exposure Via Canned Tuna Fish Consumption And Breast Cancer, Jennifer Bodenrader 2016 Walden University

Methylmercury Exposure Via Canned Tuna Fish Consumption And Breast Cancer, Jennifer Bodenrader

Walden Dissertations and Doctoral Studies

Widespread consumption of canned tuna fish since the 1950s may explain some of the increase in breast cancer prevalence in the United States and Europe. Although canned tuna is the primary source of human exposure to methylmercury, its role as an estrogen activating metalloestrogen has been overlooked in the etiology and incidence of breast cancer. Carcinogenic theory asserts that increased exposure to estrogen elevates the risk of breast cancer. The purpose of this population-based, case control study was to examine the association between canned tuna consumption, total blood mercury, and breast cancer in the NHANES 2003-2006 surveys. A multivariable logistic …

Evaluation Of Active And Passive Neonatal Tetanus Surveillance Systems In Katsina State, Nigeria, Shafique Sani Nass

Walden Dissertations and Doctoral Studies

The incidence and mortality rates of neonatal tetanus (NNT) remain underreported in Nigeria. This cross-sectional study was guided by the Mosley and Chen's model for the elements of child survival in developing countries. The goals of the study were twofold: (a) to compare the NNT prevalence and the mortality rates from the existing surveillance system and active surveillance of health facility records in 7 selected health facilities from 2010 to 2014 in Katsina state, Nigeria and (b) to assess the associations between selected NNT risk factors, number of maternal tetanus toxoid injections, frequency of antenatal visits, place of delivery, and …


Socioeconomic Responsibility And Its Effect On Hypertension Among West African Immigrants In The United States, Chryss Arekhandia Okonofua 2016 Walden University

Socioeconomic Responsibility And Its Effect On Hypertension Among West African Immigrants In The United States, Chryss Arekhandia Okonofua

Walden Dissertations and Doctoral Studies

Native-born African Americans (NBAA) bear a disproportionate burden of the effect of hypertension (HTN) in comparison to other racial groups in the United States. West African immigrants (Foreign-born African Americans) appear to carry a heavier burden than the NBAA in the United States. Using the social support theory as a guide, this study examined the association between the need to meet socioeconomic responsibility of financial and familial obligations (SERFFO) and perceived stress and the increased likelihood of HTN among West African immigrants, aged 25-54 years, in the United States. In this quantitative, cross-sectional design, self-reported data were collected from a …


Transcriptome Analysis Of Vaccine Responses To Francisella Tularensis Or Venezuelan Equine Encephalitis Virus, Rebecca Ann Erwin-Cohen 2016 Walden University

Transcriptome Analysis Of Vaccine Responses To Francisella Tularensis Or Venezuelan Equine Encephalitis Virus, Rebecca Ann Erwin-Cohen

Walden Dissertations and Doctoral Studies

The lack of vaccines for emerging and re-emerging diseases highlights technical gaps and indicates a need for innovative approaches to produce new vaccines. Vaccines may be improved by knowledge of host responses to vaccination, disease pathogenesis, and the effect of age and genetics on vaccine outcome. This study's purpose was to quantitatively assess the molecular epidemiology of Francisella tularensis (Ft) and Venezuelan Equine Encephalitis Virus (VEEV). Study results support the Epidemiology Nexus model which holds that association of changes in gene expression to vaccination facilitate understanding the mechanisms of immune development and link public health and disease epidemiology. My research …

Time To Diagnosis Of Second Primary Cancers Among Patients With Breast Cancer, Edward Okezie Irobi

Walden Dissertations and Doctoral Studies

Many breast cancer diagnoses and second cancers are associated with BRCA gene mutations. Early detection of cancer is necessary to improve health outcomes, particularly with second cancers. Little is known about the influence of risk factors on time to diagnosis of second primary cancers after diagnosis with BRCA-related breast cancer. The purpose of this cohort study was to examine the risk of diagnosis of second primary cancers among women diagnosed with breast cancer after adjusting for BRCA status, age, and ethnicity. The study was guided by the empirical evidence supporting the mechanism of action in the mutation of BRCA leading …


Interrelationships Of Colorism, Violence, And Sexual Behaviors Among Southern African American Women., Phaedra Christensen 2016 Walden University

Interrelationships Of Colorism, Violence, And Sexual Behaviors Among Southern African American Women., Phaedra Christensen

Walden Dissertations and Doctoral Studies

Two significant public health concerns that threaten both the physical and mental health of African-American women are Intimate Partner Violence (IPV) and Human Immunodeficiency Virus (HIV). African-American women (AAW) in the south carry the greatest burden of HIV and disproportionately represent the region with an incidence of 71% for new HIV infections, and elevated rates of morbidity and mortality. In 2013, the murder rate among AAW was 2.5 times higher than it was among Caucasian women. Most of the published studies that explored the association between IPV and HIV had mixed populations, did not explore topics unique to AAs, or …

Essential hypertension (HTN) has been and continues to be a serious public health problem across the globe, particularly among Black races, with an estimated morbidity rate of over 1 billion people and an estimated mortality rate of 9.4 million people worldwide. Essential HTN can lead to a host of chronic diseases including cardiovascular disease (CVD), stroke, myocardial infarction, brain damage, kidney failure, and retinopathy. The main purpose of this quantitative, descriptive, nonexperimental study was to investigate the association of physical inactivity, length of stay in the United States, immigrants' health status, and food security as risk indicators in the development …


Environmental Factors Associated With Body Mass Index Among Long Haul Truck Drivers, Charlotte Hughes Huntley 2016 Walden University

Environmental Factors Associated With Body Mass Index Among Long Haul Truck Drivers, Charlotte Hughes Huntley

Walden Dissertations and Doctoral Studies

In 2009–2010, the prevalence of obesity among U.S. adults was 40%, and the prevalence was 69% among long haul truck drivers. Researchers have not established a clear relationship between working environment and weight among truck drivers. This quantitative cross-sectional study, using an ecological framework, evaluated the relationship between the working environment (sleep performance, food choices, driving environment, and activity level) and weight severity (e.g., body mass index [BMI]) among long haul truck drivers. One hundred and twenty six adults (46 + 10, years of age), including both genders (male = 97 and females = 29) completed an online questionnaire evaluating …


Progesterone-Only Oral Contraceptive Pill, Breast Cancer, Heart Disease, And Stroke, Marsha Ema Samson 2016 University of South Carolina

Progesterone-Only Oral Contraceptive Pill, Breast Cancer, Heart Disease, And Stroke, Marsha Ema Samson

Theses and Dissertations

There is evidence from earlier studies that oral contraceptive pills may be a risk factor for certain chronic diseases, including heart disease, stroke, and breast cancer. Previous studies mainly focus on the estrogen component of combined (estrogen+ progestin) oral contraceptives (COCs) due to their popularity. This focus limits our understanding of progestin-only contraceptives and its relationship to commonly occurring chronic diseases. To provide insight into alternative methods of oral contraception, this dissertation explores the relationship between progestin-only oral contraceptive (POC) pills and heart disease, stroke, and breast cancer. We hypothesize that women using POCs are less likely to have certain …


Association Between Biopsychosocial Factors And Physical Activity Among U.S. Stroke Survivors, Claire Johnson 2016 Walden University

Association Between Biopsychosocial Factors And Physical Activity Among U.S. Stroke Survivors, Claire Johnson

Walden Dissertations and Doctoral Studies

Stroke causes substantial morbidity and mortality, and physical activity can reduce the risk of stroke occurrence. The purpose of this study was to test the association between biopsychosocial factors and levels of physical activity and to develop a model to predict inactivity for US stroke survivors. A quantitative, cross-sectional analysis was performed of the 2013 National Health Interview Survey (NHIS), which is a representative sample of US households. Association for 1,077 stroke survivors was tested with chi-square between physical activity and independent variables: biological factors (age, sex, race, body mass index, musculoskeletal conditions, and cardiovascular diseases), psychological factors (mental distress, …


Characteristics Of Adult Icu Patients With Device Associated Nosocomial Infections, Doramarie Arocha 2016 Walden University

Characteristics Of Adult Icu Patients With Device Associated Nosocomial Infections, Doramarie Arocha

Walden Dissertations and Doctoral Studies

Nosocomial infections are a cause of concern for hospital patients and the incidence rates of these infections are greater in intensive care units (ICUs) due to the invasive nature of treatments, additional risk factors and comorbidities, and therapies used. Invasive devices, such as vascular central lines, Foley catheters, and mechanical ventilators pose a risk for critically ill patients in the ICUs to develop device-related, healthcare-associated infections (HAI). The purpose of this study was to describe the epidemiological characteristics of patients who developed device-related HAIs within 3 ICU units (medical-surgical, cardiovascular, and neurosurgical) of an academic medical facility. The ecosocial theory …


Perceptions Of Behavioral And Lifestyle Changes Among African American Women With Type 2 Diabetes, Myriam Almonor 2016 Walden University

Perceptions Of Behavioral And Lifestyle Changes Among African American Women With Type 2 Diabetes, Myriam Almonor

Walden Dissertations and Doctoral Studies

The prevalence of type 2 diabetes (T2D) continues to rise and is predicted to increase to 30 million people by 2030 in the United Sates alone. African Americans (AA) have one of the highest prevalence rates of T2D among all ethnic groups. African American Women (AAW) are 100% more likely to develop T2D compared with their white counterparts. The aim of this study was to quantitatively investigate the relationship of the perceptions of AAW not previously identified that could lead to a reduction in risk of T2D among AAW. A cross-sectional study of 183 AAW 20 to 65 years old …


Symptom Presentation Frequency And Severity Associated With Adult Lyme Disease By Ross Scale Review, Vicki A. Stanavitch 2016 Walden University

Symptom Presentation Frequency And Severity Associated With Adult Lyme Disease By Ross Scale Review, Vicki A. Stanavitch

Walden Dissertations and Doctoral Studies

Although Lyme disease is the most frequently reported vector-borne illness in the United States, recent evidence from the CDC suggests that Lyme disease incidence in the United States may be much higher than reported. Lyme disease symptoms can be mistaken for a wide variety of diseases, which can complicate the diagnosis. To date, no diagnostic criteria analysis has been conducted examining the association between sociodemographic variables (sex and age) and seasonality of infection with the severity and symptomology found in Lyme disease cases. Using the CDC's outbreak investigation model, a primary case/control study was conducted using the ROSS Scale to …


Effects Of Social Support On Cardiac Recurrence Among African Americans, Yolanda Phillips 2016 Walden University

Effects Of Social Support On Cardiac Recurrence Among African Americans, Yolanda Phillips

Walden Dissertations and Doctoral Studies

Heart disease is the leading cause of death among African Americans. Despite advances in treatment modalities, based on better understanding of the disease's pathology and access to health care, African Americans continue to die from heart disease at rates significantly higher than other races. The available literature on cardiovascular disease among African Americans does not adequately explore how social support affects heart health in this group. The purpose of this study was to examine the effects of social support on cardiac recurrence among African American adults. Cohen's ISEL support system variables: tangible, appraisal, belonging, and self-esteem; and five demographic variables: …
