Disordered Eating Habits And Behaviors Among Elite Collegiate Athletes, Ann M. Armes

Theses and Dissertations--Nutrition and Food Systems

Eating disorders and disordered eating habits and behaviors were measured using the Eating Disorders Inventory-3 Referral Form (EDI-3 RF). The sample consisted of 159 elite, collegiate student athletes, males and females, aged 18 to 22. Five sports were represented, including basketball, gymnastics, soccer, swimming & diving, and volleyball. Overall, findings support the position that athletes, as a distinct population, and specifically female athletes and those that participate in lean sports, are at an increased risk for disordered eating behaviors and diagnosable eating disorders. Of the 159 total athletes that completed the questionnaire, 33% (n=53) of the athletes sampled met one …

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 the …

Polyphenols, Inflammation, And Cardiovascular Disease, Christy Tangney, Heather E. Rasmussen

Department of Nutrition and Health Sciences: Faculty Publications

Polyphenols are compounds found in foods such as tea, coffee, cocoa, olive oil, and red wine and have been studied to determine if their intake may modify cardiovascular disease (CVD) risk. Historically, biologic actions of polyphenols have been attributed to antioxidant activities, but recent evidence suggests that immunomodulatory and vasodilatory properties of polyphenols may also contribute to CVD risk reduction. These properties will be discussed, and recent epidemiological evidence and intervention trials will be reviewed. Further identification of polyphenols in foods and accurate assessment of exposures through measurement of biomarkers (i.e., polyphenol metabolites) could provide the needed impetus to examine …

Plant Calcium Content: Ready To Remodel, Jian Yang, Tracy Punshon, Mary Lou Guerinot, Kendal D. Hirschi

Dartmouth Scholarship

By identifying the relationship between calcium location in the plant cell and nutrient bioavailability, the plant characteristics leading to maximal calcium absorption by humans can be identified. Knowledge of plant cellular and molecular targets controlling calcium location in plants is emerging. These insights should allow for better strategies for increasing the nutritional content of foods. In particular, the use of preparation-free elemental imaging technologies such as synchrotron X-ray fluorescence (SXRF) microscopy in plant biology may allow researchers to understand the relationship between subcellular location and nutrient bioavailability. These approaches may lead to better strategies for altering the location of calcium …

Food Environment And Childhood Obesity, Yucong Jiao

Graduate Theses and Dissertations

This thesis examines whether children's food environment, especially food stores that have fresh produce, affects obesity prevalence among elementary school children in the state of Arkansas. Misclassified food outlet types in the Dun and Bradstreet commercial data set were first corrected and then food environment measures were computed and aggregated to geographic regions corresponding to school attendance areas. After applying classical panel estimation, it was found that the fixed effects model fit the data best. Results indicate that an additional supermarket within a one-mile radial of the census neighborhood block center will bring down childhood obesity prevalence by 0.58 percent, …

The Relationship Between Self-Efficacy And Fluid,And Dietary Compliance In Hemodialysis Patients, Ansy Paul John

UNLV Theses, Dissertations, Professional Papers, and Capstones

Patients with end-stage renal disease (ESRD) who receive hemodialysis often fail to follow a prescribed diet and fluid regimen, which undermines the effectiveness of care and leads to unpredictable disease progression and greater likelihood of complications. Non-adherence to dietary and fluid limitations compromises the outcomes of patients receiving hemodialysis. Noncompliance can lead to detrimental long-term outcomes including deterioration of the cardiovascular system, heart failure, hypertension, and pulmonary edema as well as short-term problems such as edema, itching, bone pain, and breathlessness.

Many studies have demonstrated that self-efficacy strategies are associated with improved dietary and fluid compliance among individuals receiving hemodialysis. …

Nutritional Management Of The Extremely Low Birth Weight Infant: An Evidence Based Clinical Practice Guideline, Dana J. Lunde

UNLV Theses, Dissertations, Professional Papers, and Capstones

Premature birth has risen steadily over the last decade resulting in an increased number of infants needing neonatal intensive care. The demand for neonatal intensive care has lead to many improvements in the delivery of such care with an increase in the survival of the smallest and most premature infants. However, most of these infants are being discharged from neonatal intensive care units (NICU) with severe extrauterine growth restriction (EUGR).

Extremely low birth weight (ELBW) infants born at 23-27 weeks gestation and who have a weight of less than 1,000 grams are at the highest risk for EUGR because of …

Cgi-58/Abhd5-Derived Signaling Lipids Regulate Systemic Inflammation And Insulin Action, Caleb C. Lord, Jenna L. Betters, Pavlina T. Ivanova, Stephen B. Milne, David S. Myers, Jennifer Madenspacher, Gwynneth Thomas, Soonkyu Chung, Mingxia Liu, Matthew A. Davis, Richard G. Lee, Rosanne M. Crooke, Mark J. Graham, John S. Parks, Dawn L. Brasaemle, Michael B. Fessler, H. Alex Brown, J. Mark Brown

Department of Nutrition and Health Sciences: Faculty Publications

Mutations of comparative gene identification 58 (CGI-58) in humans cause Chanarin-Dorfman syndrome, a rare autosomal recessive disease in which excess triacylglycerol (TAG) accumulates in multiple tissues. CGI-58 recently has been ascribed two distinct biochemical activities, including coactivation of adipose triglyceride lipase and acylation of lysophosphatidic acid (LPA). It is noteworthy that both the substrate (LPA) and the product (phosphatidic acid) of the LPA acyltransferase reaction are wellknown signaling lipids. Therefore, we hypothesized that CGI-58 is involved in generating lipid mediators that regulate TAG metabolism and insulin sensitivity. Here, we show that CGI-58 is required for the generation of signaling lipids …
