The Association Of Gender And Socioeconomic Position With Cardiorespiratory Fitness In Adolescents, Quentin Oliphant Jan 2015

The Association Of Gender And Socioeconomic Position With Cardiorespiratory Fitness In Adolescents, Quentin Oliphant

Walden Dissertations and Doctoral Studies

This meta-analysis investigated the association of gender and socioeconomic position with cardiorespiratory fitness in adolescents. Public health professionals know the importance of physical activity level as a modifiable behavior; however, the literature has revealed that more research is needed on the association of sociodemographic variables like gender and socioeconomic position with cardiorespiratory fitness in adolescents. Using the physical fitness and health outcomes conceptual model as a guide, the overall effect sizes across studies were assessed as well as the moderators of study design, sample size, age, and country. A systematic review of literature identified a total of 18 peer-reviewed studies ...


Impact Of Whole Grain Consumption Compliance On Gluten Sensitivity And Bowel Health, Sarah Anne Roberts Jan 2015

Impact Of Whole Grain Consumption Compliance On Gluten Sensitivity And Bowel Health, Sarah Anne Roberts

Walden Dissertations and Doctoral Studies

While many health benefits have been associated with increased whole grain consumption, current researchers have not considered if the consumption of whole grains in currently recommended or higher amounts actually leads to health problems, specifically to a correlated increase in gluten sensitivity. The purpose of this study was to determine if diets high in whole grains or those that met the recommended daily intake of whole grains help minimize or increase gluten sensitivity, and when whole grains are consumed as recommended if they cause more harm than good. The theoretical basis for this quantitative, cross sectional design was the precaution ...

Quantitative Study Of Clostridium Difficile Incidence Related To Influenza And Antimicrobial Use, Eileen M. Yaeger

Walden Dissertations and Doctoral Studies

In the United States, influenza causes approximately 36,000 deaths and over 200,000 hospitalizations each year with elderly most often affected. Clostridium difficile infection (CDI) is another major health care challenge and pressing public health issue associated with 14,000 deaths and over 335,000 hospitalizations annually. The use of antibiotics has been implicated in the development of CDI. This study's purpose was to test the relationship of seasonal influenza incidence and antiviral/antibiotic use in CDI development among hospitalized patients. Grounded in the epidemiologic wheel model of man-environment interactions, this retrospective observational study described and analyzed data ...


Herpes Virus Infections, Inflammatory Markers And Risk Of Developing T2dm And Cvd: An Analysis Of Nhanes With Adults, Aged 20-49, 1999-2010, Margarita Irizarry-De La Cruz Jan 2015

Herpes Virus Infections, Inflammatory Markers And Risk Of Developing T2dm And Cvd: An Analysis Of Nhanes With Adults, Aged 20-49, 1999-2010, Margarita Irizarry-De La Cruz

Walden Dissertations and Doctoral Studies

Herpes simplex viruses (HSVs), are among the most virulent and widespread pathogens; they affect 60-90% of the population worldwide. Substantial evidence indicates a possible association between pathogens and chronic disease. HSVs, among other viruses, have been associated with increased risk for inflammatory diseases. However, prior findings have been inconsistent on the role of infection in triggering autoimmune response and chronic disease. This study builds on the premise that pathogens can induce an inflammatory response and increase the risk for disease development. A representative U.S. sample from NHANES, a national population-based cross-sectional survey, was used to examine the relationship between ...


Examining Behavioral Reactivity And Cognitive Differences Within The Chc Theory Of Intelligence Among Children., Steven Matthew Jozwiak Jan 2015

Examining Behavioral Reactivity And Cognitive Differences Within The Chc Theory Of Intelligence Among Children., Steven Matthew Jozwiak

Walden Dissertations and Doctoral Studies

Linking cognition and behavior has long been an area of interest to the field of psychology in its endeavors to understand what innate factors influence human behavior. To date, the majority of research linking emotional reactivity to cognition has focused on single areas of intellectual functioning on specific diagnostic profiles or learning disorders rather than a comprehensive comparison to cognitive profile typology. Nearly all the research conducted to date continues to define cognition and emotion as disparate entities, rather than exploring a more integrated view of emotion and cognition. The purpose of this quantitative study was to examine cognitive profile ...


Germline Mutations In Chek1 And Chek2 In Women With Ovarian, Peritoneal, Or Fallopian Tube Cancer, Maria Isabel Harrell Jan 2015

Germline Mutations In Chek1 And Chek2 In Women With Ovarian, Peritoneal, Or Fallopian Tube Cancer, Maria Isabel Harrell

Walden Dissertations and Doctoral Studies

Ovarian cancer is the deadliest gynecological malignancy affecting women. Diagnosis often occurs late due to non-specific symptoms, but if detected early, there is excellent chance for survival. One of the most important risk factors is family history. Up to 24% of cases are due to inherited loss-of-function mutations in genes involved in the DNA damage response. The theory underlying hereditary cancers is Knudson's two-hit theory of cancer causation, where two hits are necessary for cancer to occur in an individual: one in the germline and one in the tissue. The genes, CHEK1 and CHEK2, are modulators of the DNA ...


Albumin Levels In Hispanic Dialysis Patients With And Without Type Ii Diabetes, Hector Hernandez Jan 2015

Albumin Levels In Hispanic Dialysis Patients With And Without Type Ii Diabetes, Hector Hernandez

Walden Dissertations and Doctoral Studies

Albumin provides the vital scaffolding for growth and tissue repair and supports oncotic blood pressure and hemodynamics. In hemodialysis patients, albumin aids with fluid removal by drawing excess fluid from edematous tissues back into the blood where it can then be removed by a dialyzer. The hyperglycemia seen in dialysis patients with Type II diabetes progressively damages kidney glomeruli, which permits albumin seepage into the urine, thus lowering serum albumin. The conceptual framework underpinning this research is the van't Hoff theory of osmotic pressure. Under this framework, the solute-solvent relationship largely contributes to the osmotic movement of fluid. The ...

The Burden Of Avian Influenza Viruses In Community Ponds In California, Zin Htway

Walden Dissertations and Doctoral Studies

Emerging influenza viruses continue to challenge public health. The problem is public health science professionals have been battling emerging human influenza diseases with tactile and reactionary methods because there is a lack of knowledge and data at the human-animal interface. This research was a baseline study of the proportion of influenza A virus (IAV) in urban and rural communities in California. The population was artificial recirculating water ponds in the geographic locations of rural and urban Californian communities. Surface water samples [N = 182] were collected from artificial recirculating ponds in California. Positivity for IAV was verified by real time RT-PCR ...


Testing A Structural Equation Model Of Language-Based Cognitive Fitness, Elizabeth Ann Moxley-Paquette Jan 2014

Testing A Structural Equation Model Of Language-Based Cognitive Fitness, Elizabeth Ann Moxley-Paquette

Walden Dissertations and Doctoral Studies

The normative development of language is often taken for granted, yet problems with language development can result in stress for the individual and family. A challenge with these language development problems lies within the contemporary education system, which assumes that children have appropriate skills when they begin school. The purpose of the study was to test a theoretical model of language readiness known as language-based cognitive fitness, which includes measures associated with structural concepts of language involving receptive language, expressive language, spontaneous narrative speech, and writing fluency. The sample included children from a private school who received an extensive battery ...


A Quantitative Analysis Of The Effect Of Cash-4-Grass Programs On Water Consumption, Cynthia Allen Jan 2014

A Quantitative Analysis Of The Effect Of Cash-4-Grass Programs On Water Consumption, Cynthia Allen

Walden Dissertations and Doctoral Studies

Water supplies in California are stretched to critical levels as a result of population growth, periodic drought, and climate change. The California legislature recognized that the best way to increase supply is to decrease demand so the Water Use Efficiency Senate Bill 7 (SBx7-7) was signed into law in 2009. The law requires water purveyors to reduce per capita water usage by 20% by the year 2020. To comply, water purveyors are searching for innovative ways to increase water conservation. A review of the literature has shown that many factors influence water consumption. However, the majority of household water consumption ...

Exploring Income Supplementation For Farm Sustainability, Elizabeth P. Persson

Walden Dissertations and Doctoral Studies

Sustainable farms are critical to United States’ food independence and they positively contribute to the global economy. Farms in the United States are not sustainable without profitable supplemental income. The purpose of this case study was to explore the historic profitability of farm income supplementation methods. Maslow’s hierarchy of needs theory served as the conceptual framework. A purposive sample of 25 farmers from 5 regions of the continental United States completed semistructured interviews and described their personal experiences. Archival supplemental income data came from the United States Department of Agriculture census. All the data were analyzed using coded keywords ...


Psychiatric Disorders As Potential Predictors In Medical Disease Development, Linda Kay Taliaferro Jan 2011

Psychiatric Disorders As Potential Predictors In Medical Disease Development, Linda Kay Taliaferro

Walden Dissertations and Doctoral Studies

Millions of individuals suffer disability or death from immune-based inflammatory diseases. If psychiatric disorders could be empirically linked to the prediction of immune-based inflammatory diseases, there would be a basis for promoting disease prevention measures for individuals diagnosed with one of four psychiatric disorders. Psychoneuroimmunology provided the theoretical base for understanding emotionally induced medical disease development. In this quantitative study, a parallel archival research design was used to investigate the degree to which generalized anxiety disorder, posttraumatic stress disorder, major depression recurrent, and dysthymic disorder predicted the presence of atherosclerosis, cardiovascular heart disease, rheumatoid arthritis, cancer, and type II diabetes ...


The Relationship Between Overweight And Obesity And Acculturation Of 12- To 19-Year-Old Mexican American Children, Elsa Ramirez-Brisson Jan 2011

The Relationship Between Overweight And Obesity And Acculturation Of 12- To 19-Year-Old Mexican American Children, Elsa Ramirez-Brisson

Walden Dissertations and Doctoral Studies

Mexican Americans, one of the fastest growing segments of the population, have been identified as having above-average rates of obesity. Yet, among this group, obesity rates seem to differ by immigrant status: recent immigrants, immigrants who have lived in the United States more than 15 years, and U.S.-born Mexican Americans. Guided by the acculturation phenomenon and the social ecological model, the current study assessed all 1,732 Mexican American children 12-19 years old who participated in the National Health and Nutrition Examination Survey between 2003 and 2008 to determine the association between body mass index (BMI) and language ...


Effects Of Neurofeedback On Neuropsychological Functioning In An Adult With Autism, Michael J. Lucido Jan 2011

Effects Of Neurofeedback On Neuropsychological Functioning In An Adult With Autism, Michael J. Lucido

Walden Dissertations and Doctoral Studies

Autism spectrum condition (ASC) is a complex neurodevelopmental disorder that impacts physiological processes, cognition, functional behaviors, social-communication, and often has comorbidities. One approach gaining empirical support for ASC treatment is neurofeedback. Neurofeedback uses operant conditioning to normalize cerebral activity through auditory and visual reinforcement. Live Z-score Training (LZT) has become the latest advancement in neurofeedback. There is no published research to date on LZT neurofeedback in adulthood ASC. The purpose of this study was to evaluate LZT's impact on neuropsychological measures in an adult with ASC. A multiple baseline single-case research design was used with a convenience sample of ...


Analysis Of Risk Factors Associated With Asymptomatic Colonization Of Methicillin Resistant Staphylococcus Aureus (Mrsa) Among Community College Students, Marilynn Kish-Molina Jan 2011

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 ...


Assessment, Referral, And Self Perception In Binge Eating And Obesity Among Adults, Mary Solberg Jan 2011

Assessment, Referral, And Self Perception In Binge Eating And Obesity Among Adults, Mary Solberg

Walden Dissertations and Doctoral Studies

In the past 30 years, binge eating and obesity has increased among all age groups due to lifestyle, environment, social, and biological reasons. To change eating habits, individuals may have to collaborate with others beyond the medical professional. Societal impacts of binge eating and obesity include increases in insurance rates, medical costs, and increased early-age mortality. The purposes of this study were to assess how individuals are referred to other professionals if they self-identify as binge eaters or obese and to understand personal awareness individuals had of binge eating and obesity. Cognitive behavioral theory was used as the theoretical foundation ...


A Test Of An Evolutionary Theory Of Adiposity Gain Induced By Long Sleep In Descendants Of European Hunter-Gatherers, Oleksiy Chadyuk Jan 2011

A Test Of An Evolutionary Theory Of Adiposity Gain Induced By Long Sleep In Descendants Of European Hunter-Gatherers, Oleksiy Chadyuk

Walden Dissertations and Doctoral Studies

Researchers have identified inadequate sleep duration as one of the factors contributing to global obesity. The purpose of this study was to test a hypothesis deduced from a new sleep-duration-based evolutionary theory claiming that sleep extension in response to lengthening night duration in early fall evolved into a behavioral marker of an approaching winter; this adaptive trait was theorized to produce adiposity gain in White men in response to sleep extension. The hypothesis was that White Americans would show a greater increase in the age-adjusted fat mass index per unit of sleep duration compared to that of Black Americans. Data ...

Impact Of Nutrition Education On Student Learning, Lydia Singura

Walden Dissertations and Doctoral Studies

A goal of schools is to provide students with practical nutritional information that will foster healthy lifelong behaviors. Unfortunately, students at one school were found to have difficulty grasping basic nutritional information and practical health-related skills. There remains an important gap in current literature regarding strategies to improve students' understanding of nutrition education material. The purpose of this study was to investigate the benefits of a 4-week nutrition intervention unit in the Foods I classes consisting of 82 male and female students in Grades 9-12. Constructivist teaching methods were implemented to provide students with both information and valuable skills, which ...


The Impact Of Nutrition-Teaching Self-Efficacy On Daily Fruit And Vegetable Intake, Leslie E. Rawls Hoglund Jan 2011

The Impact Of Nutrition-Teaching Self-Efficacy On Daily Fruit And Vegetable Intake, Leslie E. Rawls Hoglund

Walden Dissertations and Doctoral Studies

Lack of fruit and vegetable (FV) consumption is directly linked to the prevalence of obesity and chronic disease in the United States. The USDA Fresh Fruit and Vegetable Program (FFVP) offers elementary school teachers access to healthy foods as part of the public school classroom experience. The purpose of this study---which was based on self-efficacy theory and the socio-ecological model---was to examine if an association exists between selected factors: (a) daily fruit and vegetable consumption, training status in the USDA Fresh Fruit and Vegetable Program (FFVP), and an established school nutrition policy and (b) nutrition-teaching self-efficacy (NTSE) among elementary school ...
