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 Jan 2011

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 …


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, years living in …


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 …
