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 ...

The Effect Of Wild Blueberry Consumption On The Inflammatory Response, Oxidative Stress And Dna Damage Associated With Exercise, Taylor K. Bloedon Dec 2013

The Effect Of Wild Blueberry Consumption On The Inflammatory Response, Oxidative Stress And Dna Damage Associated With Exercise, Taylor K. Bloedon

Electronic Theses and Dissertations

At all levels of intensity and duration, exercise is known to cause an increase in the generation of reactive oxygen species (ROS). When derivatives of oxygen occur and exist independently with one or more unpaired electrons they are known as “free radicals” (Halliwell and Gutteridge 2007). Since atoms possess electrons that are usually associated in pairs, free radicals have the potential to act negatively in the body. Reactive oxygen species refer to oxygen-centered radicals as well as nonradical but reactive derivatives of oxygen (Halliwell and Gutteridge 2007). When ROS are created in excess, resulting in the disruption of the pro-oxidant ...

Natural Genetic Variation Affecting Calcium Homeostasis, Rebecca Anna Replogle Oct 2013

Natural Genetic Variation Affecting Calcium Homeostasis, Rebecca Anna Replogle

Open Access Dissertations

Calcium (Ca) is essential for multiple functions within the body including skeletal health. The level of Ca in the serum is tightly regulated. During periods of habitual low Ca intake, the body senses a decrease in serum Ca and increases renal conversion of 25 hydroxyvitamin D (25(OH)D) to 1,25 dihydroxyvitamin D (1,25(OH)2D). 1,25(OH)2D acts through the vitamin D receptor (VDR) to increase intestinal Ca absorption, renal Ca reabsorption and skeletal Ca resorption. Efficient intestinal Ca absorption, especially during periods of low Ca intake, is critical for protecting bone mass. Ca absorption ...

Regulation Of Apolipoprotein C-Iii Gene Expression By Nuclear Receptors Hepatocyte Nuclear Factor 4 Alpha And Chicken Ovalbumin Upstream Promoter Transcription Factor Ii, But Not Retinoids In Hepatic Cells, Meredith Lee Howell Aug 2013

Regulation Of Apolipoprotein C-Iii Gene Expression By Nuclear Receptors Hepatocyte Nuclear Factor 4 Alpha And Chicken Ovalbumin Upstream Promoter Transcription Factor Ii, But Not Retinoids In Hepatic Cells, Meredith Lee Howell

Masters Theses

Retinoic acid (RA) treatment induces hyperlipidemia in humans and animals. RA regulates the expression levels of various genes through the induction, repression, or coactivation of nuclear receptors, mediating its effects. RA-induced hyperlipidemia has been attributed to the induction of apolipoprotein CIII (gene, Apoc3), which inhibits lipoprotein lipase activity (LPL). We have shown that vitamin A (VA) status and retinoid treatment regulates hepatic lipogenic gene expression, suggesting that the induction of lipogenic genes may also contribute to hyperlipidemia. To test the hypothesis that retinoids may not affect Apoc3 expression, we analyzed the expression levels of Apoc3 mRNA in response to retinoid ...

Activation Of Nucleotide Binding Oligomerization Domain Containing Protein 1 In 3t3-L1 Adipocytes: Effects On Adipocyte Differentiation And Lipolysis, Jaanki Shamb Purohit

Masters Theses

Obesity, defined as having excess adipose tissue, is associated with chronic inflammation. Adipose tissue is made up of many cell types, including preadipocytes and adipocytes. Both preadipocytes and adipocytes express pattern recognition receptors that play important roles in innate immunity. Two families of pattern recognition receptors that have been studied in adipose tissue are Toll-like receptors (TLRs) and NOD-like receptors (NLRs). Activation of TLR2 and TLR4 has been shown to lead to proinflammatory response in adipocytes, which is shown to suppress adipocyte differentiation and stimulate lipolysis, one of the major physiological functions of adipocytes. However, the effects of NOD activation ...

Molecular Mechanisms Underlying The Early Life Programming Of The Liver, Gurjeev Sohi

Electronic Thesis and Dissertation Repository

Clinical studies have demonstrated that intrauterine growth restriction (IUGR) offspring, faced with a nutritional mismatch postpartum, have an increased risk of developing the metabolic syndrome. The maternal protein restriction (MPR) rat model has been extensively studied to investigate the adverse effects of a nutritional mismatch in postnatal life of IUGR offspring. Previous studies have demonstrated that MPR leads to impaired function of the liver, an important metabolic organ. However the underlying mechanisms which predispose these offspring to the metabolic syndrome remain elusive. In the following studies, low protein diet during pregnancy and lactation led to IUGR offspring with decreased liver ...
