Evaluation Of The Relationship Between Nutrition Knowledge And Disordered Eating Risk In Female Collegiate Athletes, Amy L. Miracle Dec 2013

Evaluation Of The Relationship Between Nutrition Knowledge And Disordered Eating Risk In Female Collegiate Athletes, Amy L. Miracle

UNLV Theses, Dissertations, Professional Papers, and Capstones

Involvement in collegiate sports among female athletes is at an all-time high with approximately 198,000 currently participating, (National Collegiate Athletic Association, 2012). With this increase in female participation in collegiate sports, the pressures of sport participation and academics lead some women to engage in harmful eating behaviors. These harmful eating behaviors may lead to the development of disordered eating (C. Johnson, Powers, & Dick, 1999; Quatromoni, 2008; Reel, SooHoo, Petrie, Greenleaf, & Carter, 2010; Reinking & Alexander, 2005). Many factors have been identified as contributing to the development of disordered eating but nutrition knowledge or lack thereof, has yet to be fully investigated as a potential risk factor. Female collegiate athletes may be at significant risk for disordered eating and identification of nutrition knowledge as a risk factor will aid in development of prevention and treatment interventions (Abood, Black, & Birnbaum, 2004; Schwitzer, Bergholz, Dore, & Salimi, 1998; Torres-McGehee et al., 2011). Limited information exists pertaining to the relationship between nutrition knowledge and disordered eating risk among female athletes in general (Raymond-Barker, Petroczi, & Quested, 2007) and none exists specifically for female collegiate athletes. The objective of this investigation is to determine if a relationship exists between sports nutrition knowledge and eating disorder risk in female collegiate athletes.

This research study sought to describe the correlational relationship between the variables of nutrition knowledge and disordered eating risk using the assessment tools Nutrition Knowledge & Screening (NKS) questionnaire and Female Athlete Screening Tool (FAST) questionnaire. Two hundred four female collegiate athletes completed the two questionnaires. Demographic, questionnaires and statistical data were analyzed.

The mean NKS score for all athletes was 19.2/31 (62% correct). The mean FAST score for all athletes was 59.5 which indicate that, overall, female collegiate athletes were asymptomatic. However, 19 athletes' scores classify them as having subclinical symptoms of eating disorders. Correlation analysis of NKS and FAST scores showed no correlation r (202) = -.014; p = .56 ...

Twenty subjects (10 male and 10 female) age 40 to 62 were selected based on the criteria of a diagnosis of hypercholesterolemia. Subjects were not taking any cholesterol lowering medication and had followed a calorie-controlled diet, based on either the dietary principles of the Academy or the AHA, for at least four months followed by a Paleolithic diet for four months. Multivariate analysis ...


Quality Of Olive Oils Available Locally: Chemical, Sensory And Market Investigations, Madeleine M. Gould Oct 2013

Quality Of Olive Oils Available Locally: Chemical, Sensory And Market Investigations, Madeleine M. Gould

Honors Theses and Capstones

Olive oil is a high quality food that comes at a high-quality price. Extra virgin olive oils are obtained through specific methods created to extract the highest quality oil. The world market of olive oil is rife with accusations of adulteration and false claims regarding quality. These are serious accusations, since adulteration results in lower quality oils. True extra virgin olive oils contain higher levels of beneficial compounds including antioxidant phenolic compounds. Specific mechanisms have been identified in which phenolic compounds in the olive oil matrix exhibit antioxidant activity contributing to the prevention of cancer and cardiovascular disease, among other ...

Nutritional Status In A Cohort Of Hemodialysis Patients Receiving Tocotrienol Supplementation, Rajeev Shahani Jan 2013

Nutritional Status In A Cohort Of Hemodialysis Patients Receiving Tocotrienol Supplementation, Rajeev Shahani

Wayne State University Theses

Kidney disease is defined by a loss of kidney function over time [1]. It is expressed in terms of glomerular filtration rate at five stages calculated by the MDRD formula [5]. The fifth stage (<15 mL/min/1.73m2) is designed as end stage renal disease requiring renal replacement therapy in the form of hemodialysis [5]. This requires the use of an artificial kidney (dialyzer) to filter out by-products from the blood for excretion [8]. The issue arises when toxin accumulation due to decreased renal function, dialytic factors such as incompatible dialyzer membranes reacting with blood, and co-morbid conditions such as infection or diabetes mellitus [3]. This increases inflammation within the body, leading to a negative nutrient/energy balance, resulting in a loss of body mass thereby increasing the mortality risk [10]. Tocotrienols (T3), a more potent and underutilized form of Vitamin E, are being administered to attenuate this increase in inflammation via supplementation in addition to food intake. In order to attend to this issue, the nutritional status was assessed utilizing three measures: examining nutrient intake profiles (while supplementation was taken into consideration), obtaining anthropometric findings of body mass index, and analyzing biochemical profiles of serum albumin and pro-inflammatory markers (i.e. IL-6). This data was obtained via a randomized, double blind, placebo-controlled study of 81 dialysis patients. At two times over the course of 16 weeks, blood collection for serum albumin and inflammatory markers was analyzed and dietary intake was assessed using 24-hour diet recalls and Nutritionist Pro software. Statistical analyses of paired t-tests and correlation studies revealed no significant differences between the two groups later showing no noticeable effect of T3 supplementation. Reasoning may be multifactorial such as underestimation of food intake, transcription of diet recalls may not be truly representative, or T3 supplements may not have had an effect on the nutritional statuses. It may be beneficial for patients to receive more extensive nutritional counseling as opposed to nutritional supplementation to ensure compliancy with recommended intakes.


The Mediating Role Of Dietary Patterns On The Relation Between Acculturation, Psychosocial Factors, And Cardiovascular Disease Risk Factors In The U.S. - Mexico Border, Ximena Burgos Jan 2013

The Mediating Role Of Dietary Patterns On The Relation Between Acculturation, Psychosocial Factors, And Cardiovascular Disease Risk Factors In The U.S. - Mexico Border, Ximena Burgos

Open Access Theses & Dissertations

Chronic diseases affect both, developed and developing countries around the world. In the U.S., cardiovascular diseases (CVD) are the leading cause of death for all groups including Hispanics (Heron, 2009). Hispanics are disproportionally affected by CVD and experience risk factors at higher rates than non-Hispanic whites (Swenson, 2002). Although CVD are among the most expensive and widespread health problems, they are among the most preventable. Evidence shows that diet plays a very important role in the development of chronic diseases; current dietary changes are partially responsible for the increasing epidemic of chronic diseases worldwide. It is well established that ...


Understanding The Journey: A Phenomenological Study Of College Students' Lived Experiences During The Weight-Loss Process, Michael W. Davis Jan 2013

Understanding The Journey: A Phenomenological Study Of College Students' Lived Experiences During The Weight-Loss Process, Michael W. Davis

Graduate Theses and Dissertations

Although numerous studies have focused on understanding various aspects of the science of weight loss and weight gain in college students, understanding how the weight-loss process affects college students psychologically and behaviorally may help administrators and student affairs professionals to better work with students on their campuses. The purpose of this phenomenological study was to understand the experiences of college students in the weight-loss process. Three models--Transtheoretical, Stages of Change, and Health Belief--were used as guiding frameworks and foundations to understand where the students are in the weight-loss process. The data from this study yielded four significant themes: (a) separating ...

Purpose: This research sought to gather preliminary information required to inform the development of nutrition education materials for parents, which will parallel those currently under development for teaching children in schools as part of the Australian curriculum. Research has demonstrated that while educating children about healthy eating ...


Variations Of Ghrelin, Growth Hormone, And Insulin-Like Growth Factor I In The West Indian Manatee (Trichechus Manatus), Rachel Lynn Cimino Jan 2013

Variations Of Ghrelin, Growth Hormone, And Insulin-Like Growth Factor I In The West Indian Manatee (Trichechus Manatus), Rachel Lynn Cimino

UNF Graduate Theses and Dissertations

The metabolic hormones ghrelin, growth hormone, and insulin-like growth factor I are influenced by developmental age, sex, and nutritional status in domestic and free-ranging species. However the role these hormones play has not previously been explored in sub-tropical/ tropical mammals. Furthermore, the seasonality of species with less dynamic environmental cues, such as the West Indian manatee, have not been studied. The West Indian manatee is and endangered species distributed in the southeastern United States and throughout the Caribbean basin, and its nutritional physiology is influenced by environmental factors. Understanding the hormone response to nutritional status in this species and its ...
