Impact Of Goodwill Organizations And Community Collaboration On Aids-Orphans' Needs In Nyanza Province, Kenya, Anthonia Nwagbo

Walden Dissertations and Doctoral Studies

A number of researchers have explored the toll of AIDS on the children who have become orphans as a result of the disease; others have investigated the roles of aid-giving agencies on the alleviation of the orphans' situation. However, despite researchers' pointing to the germaneness of community and goodwill agency liaison, no study had examined the impact of such collaboration on the resources available to the orphans. To this end, the heads-of-household of 532 AIDS orphans under 18 years old in Kenya's Nyanza province were surveyed to investigate the impact of community-referral on the state of AIDS orphans with regard …

Crash Risk Associated With Cellular Phone Use While Driving, Tiffani Ann Fordyce

Walden Dissertations and Doctoral Studies

There are inconsistencies in the published literature on the effect of cellular phone use while driving. The objective of this study was to estimate an adjusted nationwide crash rate associated with cell phone use while driving and to compare statewide crash rates prior to and following the implementation of legislation banning cell phone use while driving. Crash rates in nationally representative databases were calculated based on imputed values for cell phone use using the propensity score method. The imputed nationwide crash rate for fatal crashes (1.61 per 100 fatal crashes) and all crashes (1.409 per 100 crashes) represented a 2 …

The Association Between Rheumatoid Arthritis And Type 2 Diabetes Mellitus, Magaly Perez Nieves

Walden Dissertations and Doctoral Studies

A research report from the Centers for Disease Control and Prevention (CDC) indicated that more than 50% of people with diabetes mellitus (DM) in the United States (U.S.) also have arthritis. The diabetes population is disproportionately affected by arthritis, but there has been limited and inconsistent research to confirm the association between type 2 diabetes mellitus (T2DM) and rheumatoid arthritis (RA). The current study aimed to identify an association between T2DM and RA for noninstitutionalized U.S. adults between 1999 and 2012 using a nationally representative sample from the National Health and Nutrition Examination Survey (NHANES) database (n =31,488 ).

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 …

Factors Associated With Tuberculin Skin Test Positivity Prevalence In U.S. Medical Laboratory Microbiologists, Julie Ann West

Walden Dissertations and Doctoral Studies

Prior research has indicated that healthcare personnel (HCP) who work in areas where Mycobacterium tuberculosis poses an occupational hazard are at high risk of tuberculin skin test (TST) positivity and subsequent conversion to active tuberculosis (TB). U.S. medical laboratory microbiologists confront similar hazards but have not been studied outside of the HCP aggregate. The purpose of this study was to fill this gap by examining the relationships between the predictor variables of self-reported history of bacille Calmette-Guerin (BCG) immunization, place of birth, and years of laboratory experience and the outcomes of self-reported lifetime TST positivity, preventive treatment noninitiation, and barriers …

A Predictive Model For Dementia Risk In Elderly Adults With Prediabetes, Susan Elizabeth Alford

Walden Dissertations and Doctoral Studies

Dementia is a serious public health concern in the United States, with a prevalence of 5.2 million. There is currently no effective way to prevent or cure dementia, and the precise etiology is unknown, but it appears there are multiple risk factors. Prediabetes (PD) has been identified as a risk factor although the scientific evidence is conflicting. This study is important to those at high risk for dementia and to healthcare professionals who lack substantiated dementia prevention strategies. The purpose of this case control study was to determine whether PD is associated with dementia in adults aged 65-95 years and …

The South Bronx has a large minority population and a high prevalence of asthma. However, no study to date has explored the factors associated with this high prevalence rates in this population. Drawing from theories of social ecology and environmental health, the objective of this quantitative cross-sectional study is to investigate the correlates of asthma among children in the South Bronx by studying the sociodemographic and environmental risk factors, including parental occupation; neighborhood and housing characteristics, air quality, and poverty. …

Prevalence Of Neonatal Tetanus In Northeastern Nigeria, Jalal-Eddeen Abubakar Saleh

Walden Dissertations and Doctoral Studies

Although efforts have been made towards improving the health of children across the globe with notable results, neonatal tetanus (NNT) remains a major contributor to the neonatal death rates in Nigeria. This problem calls for a concerted effort by the government to achieve the revised global NNT elimination deadline of 2015. The purpose of this cross-sectional quantitative study using secondary data was to establish the prevalence of NNT in Nigeria's northeast region and to ascertain if there was any significant difference in frequency of antenatal care (ANC), trained traditional birth attendants (TBAs), and umbilical cord treatments, using single sample proportions …

The Effect Of Phytoestrogen Chemoprevention Of Prostate Cancer, Ruel Slyfield Michelin

Walden Dissertations and Doctoral Studies

Prostate cancer (CaP) remains the most commonly diagnosed cancer and second leading cause of cancer mortality among men in several ethnic groups in the United States. Lower CaP incidence among Asian men has been attributed to increased intake of soy derived phytoestrogens (SDPs); however, its association has not been extensively explored in U.S. men. The purpose of this study was to determine the effect size of serum prostate specific antigen (sPSA) and serum estradiol (sE2) following dietary SDP intervention. The study was based on an original conceptual model that aims to avert early prostate tissue damage through identification of critical …

The Relationship Between Daily Snowfall Accumulation And Pattern And Severity Of Traumatic Injuries At A U.S. Ski Resort, S. Jason Moore

Walden Dissertations and Doctoral Studies

Throughout the relevant literature, research addressing the impact of a specific environmental factor, such as snowfall, on injury patterns or severity among alpine skiers and snowboarders is sparse. The foundation for inquiry into this relationship was developed based on principles of physics and traumatology coupled with findings in the available literature. Secondary analysis of trauma registry data coupled with daily snowfall measurements from one of the largest ski areas in North America illustrated a negative correlation between daily snowfall amount and injury severity (r = -.08). Concordant findings demonstrated an increased odds of sustaining an injury defined as severe or …

Assessing The Influence Of Socioeconomic Factors, Knowledge Level, Attitudes, And Practices On Malaria Prevention Among The Gusii People Of Kenya, Christopher Nyakundi Arori

Walden Dissertations and Doctoral Studies

Global morbidity and mortality associated with malaria is rampant, and most of the clinical malaria cases are found in sub Saharan Africa. Previous and current research show that malaria is both preventable and treatable and that socioeconomic variables have a profound influence on how persons in rural Africa respond to malaria infections and the associated preventive strategies. This study assessed two key research questions for malaria cases in the Gusii region of Kenya regarding: First, whether a community education program on malaria has an impact in changing malaria preventive behaviors; and, second, if a relationship exists between socioeconomic factors and …

Association Between Vegan, Vegetarian, And Omnivorous Diets And Overweight And Obesity, Daniel Sullivan

Walden Dissertations and Doctoral Studies

Overweight and obesity and associated health risks have become epidemic in several regions around the world. Numerous studies have addressed the dietary habits of vegetarians and vegans in terms of disease prevention and nutritional deficiencies but the relationship between overweight and obesity and the demographic, psychosocial, lifestyle, and dietary intake of omnivores, vegetarians, and vegans has received less attention. Guided by the social-ecological model, this study included a cross-sectional, quantitative, anonymous web-based survey to obtain dietary information on omnivores, vegetarians, and vegans. Vegans demonstrated a significantly lower mean and median body mass index ( p=0.00) than omnivores, semi-vegetarians, and vegetarians. …

Although the incidence of breast cancer in women under 40 years of age is somewhat rare, young women tend to present with cancer that is more advanced and with poorer prognostic characteristics. This research will be important to providers, women and their families and those seeking to clarify screening guidelines. The purpose of this quantitative, retrospective, cohort study was to evaluate differences in prognostic characteristics by socioeconomic position (SIP). The cohort was comprised of females aged 18 to 39 with a primary diagnosis of breast cancer. Data were obtained from the Surveillance, Epidemiology and End Results registry for all primary …

The Relationship Of Provider Cultural Competence And Utilization Of Prenatal Care In The Hmong Of Minnesota, Cynthia J. Larson

Walden Dissertations and Doctoral Studies

Experts suggest that the cultural competence of healthcare providers is a critical factor impacting healthcare services to the ethnically diverse patient populations in the U.S. and that it may play a role in improving outcomes and reducing health disparities; however, the association between cultural competence and health outcomes remains unclear. This study used a cross-sectional quantitative design grounded by cultural competency constructs and the ethnic origins theory to explore the relationships between provider cultural competence, adequacy of prenatal care, and neonatal health outcomes in Hmong women, a population whose cultural beliefs affect their use of early and adequate prenatal care. …

Analysis Of Risk Factors Associated With Asymptomatic Colonization Of Methicillin Resistant Staphylococcus Aureus (Mrsa) Among Community College Students, Marilynn Kish-Molina

Walden Dissertations and Doctoral Studies

The bacterium Staphylococcus aureus has been an important human ailment for centuries, and with the overuse of antibiotics, methicillin resistant Staphylococcus aureus (MRSA) has emerged as a deadly, costly pathogen worldwide. Healthy carriers can become sick or can spread MRSA without symptoms. The amount of asymptomatic colonization among healthy college students and risk factors for colonization by MRSA are not well understood. According to the epidemiologic triangle model, the host (students who take antibiotics or have a history of skin infections), the infectious agent (MRSA) and the environment (direct contact with people, animals, or objects that may harbor MRSA) all …

A Sibling Case-Control Study Of Maternal Prenatal Body Mass Index As A Risk Factor For Autism Spectrum Disorder, Ruth Ann Hendrix

Walden Dissertations and Doctoral Studies

The prevalence of autism spectrum disorder (ASD) is estimated to be one in every 150 births. While both genetic and postpartum environmental exposure have been linked to ASD, prenatal maternal weight has not been investigated. The objective of the study is to assess whether overweight or obesity at pregnancy is an important risk factor for the diagnosis of ASD in offspring. A case-control study was designed to answer this question using the public health ecosocial theory. The study population consisted of 70 mothers, who were recruited via the Internet using the viral expansion loop. Multiple logistic regression analysis was used …

The Mediating Role Of Psychological Distress In The Relationship Between Adverse Childhood Experiences And Adult Smoking, Tara Wynn Strine

Walden Dissertations and Doctoral Studies

While research has indicated that impaired mental health partially mediates the relationship between adverse childhood experiences (ACEs) and alcohol and illicit drug use, little research has examined potential mediators in the relationship between ACEs and smoking, the number one cause of preventable mortality in the United States. Accordingly, this study examined the potential mediating effect of psychological distress on the relationship between ACES and smoking using data from Wave II of the ACE Study, a cross-sectional study completed between June and October of 1997 on a sample of adult health maintenance organization members (N = 7,211). The theoretical underpinnings for …

Immigration And Obesity In African American Adults Residing In The United States, Julius N. Ade

Walden Dissertations and Doctoral Studies

Obesity increases risk for heart disease, hypertension and other chronic diseases, and it affects minority ethnic groups disproportionately. However, it is unknown if African American immigrant adults, an increasing segment of the population, are at higher risk for obesity than African American non-immigrant adults residing in the United States. This study examined the association of obesity and immigrant status by comparing African American immigrant adults now residing in the United States to the general population of African American adults. The socio-ecological model provided the conceptual framework for this study. This study used a cross-sectional quantitative self-administered web-based survey to collect …

The Effect Of Direct Contact On Public Attitudes Towards People Living With Human Immunodeficiency Virus (Hiv) And Acquired Immune Deficiency Syndrome (Aids) In Zimbabweans, Mavis Mashingaidze

Walden Dissertations and Doctoral Studies

Stigma surrounding HIV and AIDS poses a significant threat to the curtailing of the epidemic by acting as a barrier to HIV testing and disclosure of serostatus. Previous research in the United States found personal knowledge of someone with HIV/AIDS to be a predictor of lower levels of HIV/AIDS-related stigma. However, no study to date has examined this relationship in Zimbabweans. Allport's contact hypothesis was hypothesis was the theoretical frame used to assess the effect of direct contact on public attitudes towards people living with the human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) in Zimbabweans with the …

Clinical Recognition Of Obstructive Sleep Apnea In A Population-Based Sample, Mark R. Zellmer

Walden Dissertations and Doctoral Studies

Obstructive sleep apnea (OSA), a disorder in which the airway intermittently collapses and obstructs during sleep, is associated with increased cardiovascular and cerebrovascular morbidity and mortality, increased risk of motor vehicle accidents, metabolic syndrome, hypertension, and depression. Treatment of OSA attenuates or reverses many of these associated risks. However, most cases of OSA are unrecognized and untreated. The two most recent studies using 1990s data found that only 6.5 - 15.4% of OSA cases, depending on severity, are clinically recognized in mixed gender populations. Based on a conceptual framework of improved physician awareness of OSA, and reduced diagnostic access bias …

Risk Factors For Development Of High Blood Pressure And Obesity Among African American Adolescents, Monique Shanta White

Walden Dissertations and Doctoral Studies

Childhood obesity has reached epidemic proportions in the United States and has been linked to hypertension, especially among African American youth. Optimistic bias leads youth to underestimate their susceptibility to negative health outcomes. Public health officials want to reduce risk factors to result in significant long term reduction in cardiovascular disease. The purpose of this study was to explore adolescent behavior practices in a school district and prevalence of high blood pressure and obesity in that population. The health belief model guided the framework for this study. Research questions examined relationship between individual health risk practices and optimistic bias on …

Racial /Ethnic Disparities In Hypertension In United States Residents: A Cross-Sectional Study Of Potential Explanatory Covariates, Franklin I. Opara

Walden Dissertations and Doctoral Studies

Racial/ethnic disparities persist in hypertension (HTN) prevalence in the United States, and African Americans are disproportionately affected. The incidence is more than two-folds in African Americans compared to Caucasians, and mortality is highest among African Americans. Understanding the risk factors in HTN and how these factors vary across racial/ethnic groups is essential to reducing the mortality among African Americans. This study examined the prevalence of HTN among a sample non-institutionalized U.S. residents (N = 30,852), assessed racial/ethnic disparities and determined factors associated with racial/ethnic variance in HTN. A cross-sectional design was used to address these aims, utilizing the National Health …

Vulnerable populations, including immigrants, are often at risk for human immunodeficiency virus (HIV) infection because of their risk-taking behaviors. This study investigated risk-taking behavior for HIV infection among Sub-Saharan African (SSA) immigrants in United States. Using social capital as a theoretical foundation, the study aimed to address the question, is there any association between social capital assets of educational opportunity, employment, and eligibility for social assistance and HIV risk-taking behavior, defined as condom use before sex (CUBS) among SSA immigrant in the U.S? Potential participants were recruited through religious and social organizations in a southwestern US state. The survey generated …

Foodborne Or Pandemic: An Analysis Of The Transmission Of Norovirus-Associated Gastroenteritis And The Role Of Food Handlers, M. S. Dreyfuss

Walden Dissertations and Doctoral Studies

This study examined the strength of association between food workers and food to norovirus in comparison to bacteria associated with foodborne-related gastroenteritis by whether norovirus had a direct (physical evidence), indirect (statistical evidence), or suspect (neither of the two) association with food or food handlers. The Centers for Disease Control and Prevention considers norovirus to cause the largest number of foodborne-related gastroenteritis cases in the United States. The association of norovirus with foodborne outbreaks through its information data collection form focuses on the food worker as the typical source. Yet, many outbreaks are not foodborne in nature. The gap in …

Prognostic Factors Of Varying Treatment Outcomes For Onychomycosis (Nail Fungal Infection) Patients, Bin Cai

Walden Dissertations and Doctoral Studies

Prevalence of onychomycosis, as high as 26.9% in the general population, can be reduced by improving current antifungal treatment. This could be accomplished by understanding prognostic factors, especially healthy nail growth, associated with achieving complete cure. This population-based study aimed to evaluate if healthy nail length or percentage of total full nail length as healthy can be early indictors for complete cure. Logistics regression analyses were performed by comparing variables between a population who achieved the complete cure and a population who failed after both populations received the same antifungal treatment in two large randomized double-blinded clinical trials that assessed …
