Influence Of Overweight, Obesity, Social Support, And Self-Efficacy On Breastfeeding Outcomes Among African-American Women, Elizabeth Hoo

Walden Dissertations and Doctoral Studies

Breastfeeding reduces morbidity and mortality among mothers and children, yet African-American women breastfeed at lower rates than women of other racial and ethnic groups do. Higher rates of overweight, obesity, and low socioeconomic status may be contributing factors in this population; however, limited research exists regarding the roles of maternal overweight and obesity on breastfeeding outcomes. The purpose of this study was to examine whether social support and self-efficacy positively influence breastfeeding outcomes among overweight and obese African American women. Self-efficacy and social support theories provided the theoretical framework for the study. Research questions examined whether (a) maternal overweight and …

Regulation Of Obesity And Metabolic Complications By Gamma And Delta Tocotrienols, Lu Zhao, Xiefan Fang, Maurice R. Marshall, Soonkyu Chung

Department of Nutrition and Health Sciences: Faculty Publications

Tocotrienols (T3s) are a subclass of unsaturated vitamin E that have been extensively studied for their anti-proliferative, anti-oxidative and anti-inflammatory properties in numerous cancer studies. Recently, T3s have received increasing attention due to their previously unrecognized property to attenuate obesity and its associated metabolic complications. In this review, we comprehensively evaluated the recent published scientific literature about the influence of T3s on obesity, with a particular emphasis on the signaling pathways involved. T3s have been demonstrated in animal models or human subjects to reduce fat mass, body weight, plasma concentrations of free fatty acid, triglycerides and cholesterol, as well as …

Herein, 1) the lipid-lowering role of EA was identified in primary human adipose stem cells (hASCs) and human hepatoma Huh7 cells; 2) the molecular mechanisms by which EA attenuates adipogenesis by epigenetic modification were identified; 3) the effects of EA on high fat and high sucrose-mediated obesity was …

Hospital Practices Related To Breastfeeding In Mississippi: A Socio-Ecological Approach, Amir Alakaam

Dissertations

Mississippi continues to have one of the lowest rates and the weakest support in respect to breastfeeding in the nation (Centers for Disease Control and Prevention, 2014a). Hospital practices supporting breastfeeding such as the Ten Steps to Successful Breastfeeding (TSSB) can dramatically increase breastfeeding rates and duration (Rosenberg, Stull, Adler, Kasehagen, & Crivelli-Kovach, 2008). The aim of this study was to explore breastfeeding practices in Mississippi hospitals based on two levels of the Socio-Ecological Model: the organizational level (phase I) examined the hospital practices based on the level of implementation of the TSSB; the individual level (phase II) examined knowledge …

Activation Of Toll-Like Receptor 4 (Tlr4) Attenuates Adaptive Thermogenesis Via Endoplasmic Reticulum Stress, Meshail Okla, Wei Wang, Inhae Kang, Anjeza Pashaj, Timothy P. Carr, Soonkyu Chung

Department of Nutrition and Health Sciences: Faculty Publications

Background: Human obesity is associated with defective brown adipose tissue (BAT) activation.

Results: Toll-like receptor 4(TLR4) activation by high fat diet or lipopolysaccharide impairs adaptive thermogenesis.

Conclusion: Obesity-mediated TLR4 activation represses adaptive thermogenesis through endoplasmic reticulum (ER) stress-mediated mitochondrial dysfunction.

Significance: Inhibition of TLR4/ER stress axis is a novel target to augment BAT activity.

Abstract: Adaptive thermogenesis is the cellular process transforming chemical energy into heat in response to cold. A decrease in adaptive thermogenesis is a contributing factor to obesity. However, the molecular mechanisms responsible for the compromised adaptive thermogenesis in obese subjects have not yet been elucidated. In …

Children's Picky Eating And The Role Of Family Environments, Maureen Lyons

Journal of Undergraduate Research at Minnesota State University, Mankato

Picky eating is often seen as a temporary phase that children go through in the developmental process. While some children never exhibit picky eating behaviors, others seem to get stuck in the tendency of judging foods, which they have never tried, based upon a pretense that the food might not meet with their satisfaction. Learning more about children’s preferred food groups and types of foods, along with the family environmental factors experienced by these children may help to understand ways to support children who struggle with picky eating. Introducing children to new foods within a positive atmosphere, where they are …

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Cereal fibers that can be metabolized by gut microbiota have been shown to promote the growth of beneficial bacteria in the gut. Increased consumption of cereal fibers may improve host / gut microbiota interactions in obesity and other metabolic diseases by normalizing gut dysbiosis. The present dissertation describes four research projects to assess the impact of cereal dietary fibers on gut microbiota and host metabolism. In the first study, we determined the treatment temperatures for production of soluble, non-digestible, feruloylated oligo- and polysaccharides (FOPS) from maize bran and wheat bran, and determined the fermentation properties of partially purified FOPS from …

The Longitudinal Effects Of Beta-Alanine On Punch Power, Punch Frequency, And Fatigue In Female Amateur Fighters, Rodger Wayne Stewart

Graduate Theses and Dissertations

Beta-alanine is a non-essential amino acid typically obtained in the diet via high-protein foods (beef, chicken, pork, and fish) and produced in the confines of the liver. BA is a precursor to the cytoplasmic dipeptide carnosine (beta-alanylhistidine). Carnosine is found in high concentrations in human skeletal muscle where it plays a key role in intracellular pH buffering. Research indicates BA supplementation increased punch power, punch frequency, and lactate concentrations in male amateur fighters after 28-day supplementation. There are currently no studies evaluating the effects of BA on boxing performance variables in women. Therefore, the purpose of this study was to …

Effects Of Mild Hypohydration And Hyperthermia On Cognition And Mood In Obese And Non-Obese Females, Jenna Marie Burchfield

Graduate Theses and Dissertations

INTRODUCTION: Information regarding effects of hypohydration (HY) and hyperthermia (HT) on cognition, mood and development of symptoms is conflicting since the two conditions often confound each other. Further, although obese individuals may have physiological impairments during heat stress, whether psychological impairments occur with HY and HT is unknown. PURPOSE: To assess the independent and combined effects of mild HY and HT on cognition, mood, and the development of symptoms in obese and non-obese females. METHODS: Twenty-two healthy females (11 non-obese, 22±2y, 61±6kg, 25±4% body fat; 11 obese, 22±2y, 80±18kg, 44±5% body fat) volunteered in two randomized, repeated-measures trials, involving passive …

Hypohydration And Mood State In Free-Living Males And Females, Thomas Edward Vidal

Graduate Theses and Dissertations

Previous research has shown that acute dehydration can result in changes in mood. These changes have been reported in less than a 1% loss in total body water. However, the effect of hypohydration (i.e., reflected through high urine concentration) on mood in free-living conditions has not been studied. PURPOSE: The present study was designed to determine if hydration status is associated with mood within the general population under free-living conditions. METHODS: A group of 103 apparently healthy subjects (49 male, 54 female, 41±14 y, 1.7±0.1 m, 76.1±16.9 kg) completed three visits separated by a week. Mood was assessed by the …
