The Impact Of Dietary Protein Supplementation As Part Of A Time Restricted Feeding Eating Pattern On Sleep, Mood, And Body Composition In Adults With Overweight Or Obesity, Rebecca L. Bowie May 2022

The Impact Of Dietary Protein Supplementation As Part Of A Time Restricted Feeding Eating Pattern On Sleep, Mood, And Body Composition In Adults With Overweight Or Obesity, Rebecca L. Bowie

Graduate Theses and Dissertations

Obesity in the United States continues to increase, and effective, long-term weight loss strategies are limited. Time restricted feeding (TRF) is a dietary intervention that has potential to serve as an effective long-term weight loss strategy, however more data is needed to establish the effectiveness of a TRF eating pattern on obesity and its related health outcomes. To our knowledge, manipulation of macronutrient composition during TRF intervention and the effect of TRF on sleep and mood have not been studied. Therefore, the objective of this study was to determine the effect of protein supplementation during TRF on mood, sleep, and …


Effects Of Commercial Feed Additives On Growth Performance And Gut Microbiota Of Nursery Pigs, Xiaoyuan Wei Dec 2020

Effects Of Commercial Feed Additives On Growth Performance And Gut Microbiota Of Nursery Pigs, Xiaoyuan Wei

Graduate Theses and Dissertations

To secure animal welfare and maximum production, feed additives are often added to nursery pig diets to increase nutrition digestibility, enhance intestinal health, and prevent or mitigate disease, with the ultimate goal of improving growth performance. This thesis performed a longitudinal analysis using next-generation sequencing to investigate the dynamic changes of gut microbiota in weaned pigs fed commercial feed additives. Chapter II was used to evaluate the effects of organic acid mixture on growth performance and gut microbiota of weaning pigs. This study demonstrated that the inclusion of 0.035% (SBA0.035) or 0.070% (SBA0.070) sodium butyrate in a diet containing 0.5% …


Effects Of Multivitamin-Mineral Supplementation On Mental Health Among Young Adults, Ya-Hsuan Chang Aug 2019

Effects Of Multivitamin-Mineral Supplementation On Mental Health Among Young Adults, Ya-Hsuan Chang

Graduate Theses and Dissertations

The percentage of young adults who had mental illnesses has increased from 2008 to 2015. However, few existing studies investigating the potential benefits of multivitamin-mineral (MVM) supplementation on mental health focused on young adults (18-24 years of age), whose eating behaviors are often unhealthy. The purpose of this study was to examine the effects of a MVM supplement on mental health in young adults. One hundred and thirty-three college students (Mage=20.59, SD=1.77; 80.15% female) participated in this randomized, double-blind, placebo-controlled trial. Participants consumed either a MVM supplement or a placebo for 30 days. The supplement contained B Vitamins, Vitamin C, …


Alcohol Use, Dietary, And Exercise Behaviors: A Latent Profile Analysis Of Young Adult Lifestyle Behaviors, Ryan Wesley Grant May 2019

Alcohol Use, Dietary, And Exercise Behaviors: A Latent Profile Analysis Of Young Adult Lifestyle Behaviors, Ryan Wesley Grant

Graduate Theses and Dissertations

As individuals enter adulthood, their lifestyles and lifestyle behaviors begin to change drastically. These lifestyle behavior changes in emerging adulthood provide a foundation for future health behaviors that often persist through all of adulthood. The aim of this study was to use Latent profile analyses (LPA) to discover distinct profiles of homogenous groups of young adults based on alcohol, diet, and exercise behaviors. Overall, five distinct profiles for both males and females were identified: Moderates, Unhealthy Eaters, Medium Drinkers, Healthier Eaters and Exercisers, and Heavy Drinkers. Heavy Drinkers and Unhealthy Eaters were the highest risk groups and reported the highest …


Food Environment And Childhood Obesity, Yucong Jiao Aug 2012

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, …
