Sleep, Eat, Repeat: An Examination Of The Influence Of Sleep And Biological Sex On Eating-Related Inhibitory Control In Overweight Emerging Adults, Shelby Mika Seipert-Raine

Theses and Dissertations

Background: Lower inhibitory control has been shown to associate with greater risk for obesity in adolescence. On average, females have moderately higher rates of behavioral inhibitory control than males. These difference in inhibitory control across sex may influence overeating and development of obesity. This study examined whether sleep duration and sleep quality are associated with food-related inhibitory control and whether this association is moderated by biological sex. Methods: A total of 59 emerging adults ages 18 to 25 (37 males, 22 females) who had a BMI within the overweight or obese categories (BMI ≥25) completed self-report measures of eating and …

Obesity Knowledge And Bmi In Caregiver-Adolescent Dyads: A Descriptive Comparative Pilot Study, John Sykes, John Sykes

Theses and Dissertations

Abstract

Background: The prevalence of obesity and associated health risks and costs continue to increase. The majority of these health and cost ramifications manifest in adulthood, making it imperative to intercept the problem during childhood. Unfortunately, an overwhelming majority of the research surrounding adolescents and obesity to date involves subjects that are already overweight or obese, and the focus of those interventions are on secondary and tertiary prevention. Focusing on primary prevention of childhood obesity could ultimately decrease the incidence, prevalence, and disease-related burden to society. It is posited that the 20% difference in obesity prevalence between adults and children …

Let Go And Let God: An Ethnographic Study Of Overeaters Anonymous, Subjectivity, And Extreme Eating Distress, Abby Forster

Theses and Dissertations

Academic discussions regarding eating disorders have been dominated by two frameworks: biomedical and feminist. While the former explains eating disorders as a product of individual pathology, the latter asserts the cause is culture. An aspect of culture that is often suggested is neoliberalism. This ethnographic study utilizes the term “eating distress” to acknowledge the localized idioms that occur outside of the bounds of biomedical settings. The research documents the experiences of many members of Overeaters Anonymous dealing with eating distress within a social context in which their body types are stigmatized. The dissertation examines the relationship between subjectivity, Overeaters Anonymous, …

Greenspace Across The United States: Exploring Equity And Associations With Physical Activity, Obesity, And Health-Related Quality Of Life, Ellen W. Stowe

Theses and Dissertations

Neighborhood greenspace is important for health and well-being but may not be equitably present in neighborhoods across the United States. Also, many adults are physically inactive, have obesity, and report poor health-related quality of life. Greenspace has been tied to these health conditions, but with mixed findings. The purpose of this study was to 1) use an environmental justice perspective to examine variations in 11 measures of greenspace by neighborhood race/ethnicity, income, and rurality in block groups across the contiguous United States and 2) examine 11 greenspace measures in connection to physical activity, obesity, and health-related quality of life in …

Effectiveness Of Group Interventions For Weight Loss For Youth: A Meta-Analytic Review, Monica Carolina Martinez

Theses and Dissertations

Introduction: Nearly 19.3% of children in the United States have obesity. There are several behavioral weight loss (BWL) programs available for children and adolescents that have proven effective in managing weight. Many of these treatments are delivered to groups of children rather than to individual youth. However, previous reviews of the literature have not explored the unique effects of group treatment modalities. Research has shown that social ties, particularly with peers, have an impact on adolescents' physical activity engagement and dietary habits. Therefore, it is important to explore how the interaction component of group delivered BWL treatments contributes to their …

Masculinity And Men’S Health Attitudes Toward Consideration Of Weight-Loss Surgery, Karaline Fusco

Theses and Dissertations

The rise in obesity across the United States has led to greater educational outreach, considerable research, and medical interventions aimed at decreasing the rate of obesity-related health diseases. But are these interventions reaching everyone? Despite men and women having equivalent rates of obesity, only 20% of weight-loss surgery patients are men. While men have an average life expectancy that is 5 years less than women and are twice as likely than women to have heart disease, men also underutilize healthcare services. Given these factors, this research explored men’s health beliefs, conformity to male norms, and receptivity to weight-loss surgery. This …

Effects Of Macronutrients Intake And Physical Activity On Childhood Obesity Of Hispanic Children, Prosanta Barai

Theses and Dissertations

Obesity has become more ubiquitous during the past few decades, and still, its prevalence is increasing. It is in every population in the world and all regions, including rural parts of low and middle-income countries. In the USA, regardless of age, the severity of obesity is no different from the global trend. Although numerous pieces of literature are available, that tried to find answers to some pressing issues like how obesity can be controlled, but there is little to no study focused on younger children, especially the 4-6-year-old Hispanic population. Our study aimed to determine the causal path among literature …

Sleep And Eating Behavior Among Adolescent Females With Overweight Or Obesity: The Role Of Appetite-Related Cognitive Processes, Kirandeep Kaur

Theses and Dissertations

Insufficient sleep duration and poor sleep quality can potentiate weight gain and obesity in adolescents. Furthermore, overweight and obese females are at unique risk for insufficient sleep and associated health complications. We examined self-reported sleep duration and self-reported adequacy of sleep duration as potential moderators of the relationship between eating behavior and several cognitive processes including hedonic hunger, executive dysfunction, and self-control. We used a multisystemic conceptual framework to highlight the pathways that may explain the relationship between sleep behaviors and the Healthy Eating Index (HEI). The study employed a cross-sectional design. Participants completed baseline measures of height and weight, …

Evaluating Nutrition Knowledge In Parents And Its Relation To Childhood Obesity, Rachael Shangraw

Theses and Dissertations

This study aims to evaluate the relationship between parental nutrition knowledge and their child’s body mass index (BMI) to identify variables that are associated with increased obesity in American children. A cross-sectional study design was employed with a convenience sample of 464 parents of children between the ages of 2 and 12. Parents completed a GNKQ-R (General Nutrition Knowledge Questionnaire – Revised) survey to measure nutrition knowledge. Parents reported their child’s height and weight which was later calculated and categorized according to the Center for Disease Control’s BMI-for-age growth chart. The Kolmogorov-Smirnov Test for Normality was conducted to examine the …

Milk-Fat Intake And Differences In Abdominal Adiposity And Bmi: Evidence Based On 13,544 Randomly Selected Adults, Klarissa Rae Wilkinson

Theses and Dissertations

The primary objective of this study was to evaluate the relationship between milk-fat intake and obesity, particularly abdominal obesity, in 13,544 U.S. adults. A secondary objective was to determine the extent to which the association was influenced by multiple potential confounding variables. This cross-sectional study used data from the 2011–2016 National Health and Nutrition Examination Survey (NHANES). Level of milk-fat content regularly consumed was the exposure variable. Body mass index (BMI) and sagittal abdominal diameter (SAD), a measure of abdominal obesity, were the outcome variables. SAD correlates strongly with visceral fat, when measured by computed tomography, and has been shown …

Preventing Obesity: A Social Ecological Exploration Of Centers For Disease Control Prevention Strategies And Guidance Toward Healthy Eating, Physical Activity, And Communities, Ryan Kelly

Theses and Dissertations

Abstract

Obesity has reached nearly 40% of the adult public in the United States, costing the citizen taxpayer over $200 billion annually in healthcare costs. Those suffering from obesity deal with multiple physical and mental repercussions. Through a content analysis of four Centers for Disease Control (CDC) documents and guided by the conceptual framework of the social ecological model, this research explores the federal approach to preventing obesity. The analysis finds that CDC solutions to obesity involve connecting people to each other and healthier choices, an orientation toward local public administration, and an emphasis on environmental and infrastructure improvements.

Impact Of Sleep Duration, Sleep Quality, And Physical Activity On Obesity Indices Among Adolescents, Sarah Thompson

Theses and Dissertations

Adolescent prevalence of obesity and at-risk WC has continued to rise worldwide. Sleep duration, sleep quality, and physical activity have been hypothesized as contributing factors to this increase. PURPOSE: This study aimed to examine the sleep–obesity relation in adolescents. METHODS: Using data from the 2015-2016 NHANES(n=454; ages 16-18 years), the effect of sleep duration, sleep quality, and MVPA on BMI and WC by gender was analyzed using appropriate sampling weights. RESULTS: Longer sleep duration was associated with increased BMI (β=0.07; 0.065, p<0.05) and WC (β=0.069; 0.13, p<0.05) among males and females. Poor sleep quality was associated with increased BMI among males and females (β= 0.04; 0.08, p< 0.05). A significant main effect was observed across sleep duration, sleep quality and MVPA via multiple regression for both BMI and WC. CONCLUSIONS: For both males and females, BMI and WC were impacted by excessive sleep, poor sleep quality, and low MVPA, with greater associations among males.

Toward A Biopsychosocial Model Of Obesiy: Can Psychological Well-Being Be The Bridge To Integration?, Alexia Holovatyk

Theses and Dissertations

The complications associated with obesity are some of the most pressing health concerns facing the United States. At present, cardiovascular disease, stroke, and certain types of cancer are some of the leading causes of death, and researchers have cited obesity as one related factor (NIH, 2000). The topic of obesity has typically been approached through two seemingly contradictory lenses: The biomedical model that views obesity as a disease risk factor (e.g. Huxley, Mendis, Zheleznyakov, Reddy, & Chan, 2010) and the psychosocial model that considers the stigma associated with obesity to be more harmful than weight itself (e.g., Hatzenbuehler, Keyes, & …

Culturally-Relevant Factors That Influence Healthy Eating Among African American College Students, Danyel Smith

Theses and Dissertations

Obesity is a national epidemic in the US, disproportionately affecting African Americans, such that the obesity prevalence in African Americans (49.6%) surpassed the national prevalence (42.4%) in 2018. Those same disparities exist at the collegiate level, such that 27.4% of a sample of African Americans college students had obesity, surpassing the national prevalence of obesity (12.1%) in 2018. Diet, an important driver of obesity, is influenced by several psychological, social, and environmental factors. However, cultural factors influencing diet are understudied among African American college students. The overarching goal of the current study was to identify culturally-relevant factors that promote healthy …

Examining Body Mass Index And Sepsis Mortality At One Year After Sepsis, Jamie D. Robinson

Theses and Dissertations

Introduction: Sepsis is a serious and life-threatening syndrome affecting 1.7 million Americans annually and resulting in approximately 270,000 deaths. An “obesity paradox” where obese individuals have lower sepsis mortality than their non-obese counterparts has been described. The problem is that the longevity of the effect is unknown, and few studies have examined the obesity paradox after 1-2 months post-diagnosis.

Methods: This retrospective cohort study examined clinical, demographic, and biomarker variables thought to affect sepsis mortality at three-time points: 30 days, 180 days, and at one year post-sepsis diagnosis in order to shed light on specific factors that might define …

Perceptions Of Food, Supportive Resistance Resources, And Nutrition Knowledge Of Bariatric Surgery Patients, Savannah K. Walker

Theses and Dissertations

Adult overweight and obesity is a life-threatening health concern worldwide. Bariatric surgery is a successful treatment for severely obese individuals however, there is a moderate risk for weight regain. This study evaluated perception of food, supportive resistance resources, and nutrition knowledge, which play important roles in successful weight loss post bariatric surgery. Participants completed a three-part questionnaire at three time intervals: prior to surgery, 2 months post-surgery, and 5 months post-surgery. Results show that bariatric patients’ eating behavior significantly changes post bariatric surgery, but a disordered perception of food remains. Bariatric surgery patients believe support from significant others and family …

Genetic Determinants Of Variation In The Gh/Igf-1 Axis And Their Relationship To Cardiometabolic Health, Rafael Luis Aguirre Guillen

Theses and Dissertations

Background: In a study of Mexican Americans, we performed analyses of GEI and pleiotropy in the axis in relation to MS. GH/IGF-1 axis components were studied. Model parameters and likelihoods were estimated by maximum likelihood.

Results: Pleiotropy was observed for IGFBP3 (p

Conclusions: IGF-I and IGFBP3 are genetically correlated with MS whereas MS influences the additive genetic variance in IGFBP1 variables mainly but also in IGF-I somewhat by virtue of the VH exhibited by IGF-I/IGFBP1.

Physical Activity Level And Insulin Resistance In 6,500 Nhanes Adults: The Role Of Abdominal Obesity, James R Fowler

Theses and Dissertations

OBJECTIVE: This cross-sectional study investigated insulin resistance (IR) variation across physical activity (PA) levels in U.S. adults. METHODS: MET-minutes were utilized to quantify PA using 2 methods: 4 categories were based on relative MET-minutes, and 5 were based on U.S. PA guidelines. IR was indexed using the homeostatic model assessment (HOMA). Effect modification was tested by dividing waist circumferences into sex-specific quartiles, and then evaluating the relationship between PA and HOMA-IR within each quartile separately. RESULTS: Relative PA was associated with HOMA-IR after controlling for demographic and demographic and lifestyle covariates (F = 11.5, P < 0.0001 and F = 6.0, P = 0.0012, respectively). Adjusting for demographic and demographic and lifestyle covariates also revealed relationships between guideline-based PA and HOMA-IR (F = 8.0, P < 0.0001 and F = 4.9, P = 0.0017, respectively). Controlling for waist circumference with the other covariates nullified the relationship between PA and HOMA-IR. Effect modification testing showed that when the sample was delimited to adults with extra-large waists (Quartile 4), relative (F = 5.6, P = 0.0019), and guideline-based PA (F = 3.7, P = 0.0098) and HOMA-IR were related. PA and HOMA-IR were not related within the other quartiles. CONCLUSION: High levels of PA may play a meaningful role in glucose and insulin metabolism in those with abdominal obesity, but not in adults with smaller waists.

Physical Activity Of Preschoolers With Developmental Disabilities And Delays, Michaela A. Schenkelberg

Theses and Dissertations

Children with developmental disabilities and delays are at greater risk for developing overweight and obesity compared to typically developing peers. Participation in regular physical activity is a modifiable behavior that is consistently associated with improved weight status and other positive health outcomes. Previous studies have identified numerous individual- and environmental-level factors that associate with physical activity among school-age children with and without disabilities. However, little is known about physical activity behaviors and related correlates among preschool-aged children with disabilities (ages 3 – 5 years), especially while they are in preschool settings. Therefore, the overall purpose of this dissertation was to …

The Impact Of Sleep Restriction On Food-Related Inhibitory Control And Food Reward In Adolescents: Physical Activity And Weight Status As Potential Moderators, Kara Mcrae Duraccio

Theses and Dissertations

The present study aimed to evaluate associations between sleep duration and food-related inhibitory control and food reward in adolescents aged 12-18. Potential moderating effects of physical activity and weight status on the association between sleep, inhibitory control, and food reward were also examined. To evaluate these associations, the study employed a two-phase crossover design in which participants spent either 5 hours per night (restricted sleep) or 9 hours per night (habitual sleep) in bed for 5 nights. Participants completed a food-related inhibitory control task and a questionnaire assessing for food reward on the 6th day of each study phase. Repeated …

Total dairy consumption, type of dairy, and the relationship between race and sex were examined in 580 participants aged 18-26 years. Two-tailed correlation tests revealed a nonsignificant relationship between frequency of dairy consumption and body fat percentage among males, (r = .02, p = .68, n = 98) and females, …

Differences In Eating Patterns And Body Mass Index Of Home School Children And Public School Children, James Turner Sanderson

Theses and Dissertations

Healthy eating in childhood and adolescence is important for proper growth and development and to help prevent chronic diseases. Many factors contribute to healthy eating patterns, and one of the most influential factors is the home and school environment. Both settings have role models who may affect a child’s eating behaviors. This study consisted of 54 home school and 21 public school participants who lived in northeast Mississippi and were between 6-12 years old. Public school children consumed significantly more total calories, net carbohydrates, vitamin C, and calcium compared to the home school children. Also, the public school children consumed …

The Effects Of Exercise Training Intensities On Changes In Body Composition, Visceral Adipose Tissue, Adiponectin And C-Reactive Protein, Leslie E. Solis

Theses and Dissertations

Obesity is currently characterized as a worldwide health pandemic. Despite many efforts to provide the optimal exercise prescription to obese and overweight individuals for maximization of fat loss and decreasing metabolic risks, findings in the literature continue to remain ambiguous. This investigation aimed to examine the effects of low- vs. high-intensity short-term training on body composition and visceral adipose tissue (VAT) under equivalent caloric expenditure in overweight and obese Hispanic adults of Laredo, Texas. Additionally, it aimed to analyze how changes in body composition and VAT affect serum levels of adiponectin and C-reactive protein (CRP),bioactive chemicals utilized in the detection …

Motivators And Barriers To Health Behaviors In African American Women, Teresa M. Depratt

Theses and Dissertations

Women who identify as African American are at particularly high risk of developing obesity and associated health concerns such as diabetes, heart disease, and cancers. Eating healthfully and engaging in a minimal amount of physical activity are known to be both preventative and curative. Based on review of research, this study investigated potential constructs of Motivators and Barriers to health-supporting behaviors as they are perceived in African American women. The study also constructed a novel scale, Motivators and Barriers to Health Behaviors (MBHB), which intended to capture some constructs of each domain via two surveys. Also of interest was if …
