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 …

A Novel Approach To Reducing Adiposity Among Young Men, Jean M. Reading

Papers 1 and 2: The self-guided intervention produced modest weight …

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. The …

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 …

A Stakeholder Examination Of Gestational Weight Gain Guidelines, Melissa Kwitowski

Theses and Dissertations

Obesity is a significant health concern for women of childbearing age. More than 40% of women have a Body Mass Index (BMI) in the overweight or obese ranges at the time they conceive, posing significant health risks for both mother and child. Excessive weight gain during pregnancy is common and associated with numerous deleterious complications. The Institute of Medicine published gestational weight gain (GWG) guidelines based on prepregnancy BMI. However, more than 50% of women gain in excess of these recommendations. Further, many women report receiving minimal guidance from their healthcare providers regarding weight gain, nutrition, and physical activity during …

Integrating Obesity And Eating Disorder Prevention: A Pilot And Feasibility Trial Of Inspire, Courtney C. Simpson

Theses and Dissertations

Obesity and eating disorders are pervasive concerns among young adult women, and profoundly impact physical and psychological functioning. Weight-related disorders are typically chronic conditions; their treatment is often complex and frequently ineffective. Moreover, Black and Latina women have disproportionately high rates of obesity, and experience rates of eating disorders comparable to those of their White peers; yet, they are less likely to be referred to appropriate treatment. Given the intractability of weight-related concerns and their detrimental consequences, attempts to prevent unhealthy eating attitudes and behaviors are essential. To date, few prevention programs have significantly reduced both obesity risk and eating …

An Examination Of The Technical And Relational Hypotheses Of Motivational Interviewing In A Sample Of African American Adolescent Girls Seeking Obesity Treatment, Rachel L. Boutte

Theses and Dissertations

Adolescent obesity has increased exponentially over the past three decades in the United States. In response, behavioral interventions have been developed and implemented to address this epidemic; however, treatment adherence is often suboptimal. Motivational interviewing (MI) is a directive, person centered approach to reducing patient ambivalence about change, which has been shown to increase engagement in obesity interventions. The current study investigated the underlying process of MI by exploring two different, but related pathways that explain how change happens (e.g., the technical and relational hypotheses) in the context of a multidisciplinary obesity intervention with African American adolescent girls (N …

Obesity And Asthma: Adiponectin Receptor 1 (Adipo R1) And Adiponectin Receptor 2 (Adipo R2) Are Expressed By Normal Human Bronchial Epithelial (Nhbe) Cells At Air-Liquid Interface (Ali) And Expression Changes With Il-13 Stimulation, Jennifer L. Bradley

Theses and Dissertations

Obesity is recognized as an important risk factor for the development of many chronic diseases such as hypertension, Type 2 diabetes mellitus (T2DM) cardiovascular disease, cancer, renal disease, neurologic dysfunction, metabolic syndrome and asthma (3, 4). Circulating serum adiponectin levels in obese asthmatics have been reported to be low. Therefore, we aimed to investigate the role of adiponectin in a mucus hypersecretion model and hypothesized that adiponectin would decrease IL-13 induced MUC5AC expression from differentiated NHBE cells and that increasing concentrations of IL-13 would cause a decrease in Adipo R1 and Adipo R2 expression. MUC5AC expression with exposure to adiponectin …

Pathways Linking Sleep Timing To Obesity In Midlife Women, Dana R. Schreiber

Theses and Dissertations

Midlife women are vulnerable to developing obesity. Both sleep timing and negative emotion are risk factors, yet limited research has explored their role on weight outcomes in this population. The current investigation explored the association of sleep timing (i.e., mean sleep time, sleep time variability) and obesity (i.e., BMI, waist circumference) in midlife women, considering emotional pathways (i.e., depressive symptoms, anger) that might mediate this association. PROCESS parallel mediation models assessed direct and indirect pathways. In follow-up analyses, sleep duration was explored as an indirect pathway linking sleep timing to obesity. Results demonstrated that sleep timing does not directly predict …

Nourish-C: Implementing A Family Based Weight Loss Intervention In A Church Community, Jacqueline Woods

Theses and Dissertations

Increasing rates of obesity across all race, ethnic, gender, and age groups over the past thirty years have generated significant public health concern. Black children face disproportionately higher risk for overweight and obesity compared with their White peers. Substantial evidence suggests that parent involvement improves pediatric obesity treatment outcomes. Moreover, churches are feasible and culturally congruent places to host health promotion interventions within the Black community. The current study examined the feasibility of disseminating an existing pediatric obesity intervention, NOURISH, in Black church communities. Twenty-five families participated in baseline assessment of the NOURISH-C. Five churches hosted the intervention and eight …

A Comparison Of Obesity Interventions Using Energy Balance Models, Marcella Torres

Theses and Dissertations

An energy balance model of human metabolism developed by Hall et al. is extended to compare body composition outcomes among standard and proposed obesity interventions. Standard interventions include a drastic diet or a drastic diet with endurance training. Outcomes for these interventions are typically poor in clinical studies. Proposed interventions include a gradual diet and the addition of resistance training to preserve lean mass and metabolic rate. We see that resistance training, regardless of dietary strategy, achieves these goals. Finally, we observe that the optimal obesity intervention for continued maintenance of a healthy body composition following a diet includes a …

Motivation, Mindfulness, And Metabolic Factors Predicting Adolescent Adherence And Attrition In A Multidisciplinary Weight Management Program, Stephen Trapp

Theses and Dissertations

Estimated rates of obesity are notably high in the United States and pose a significant public health concern. A number of deleterious physical and psychosocial conditions are associated with pediatric obesity and the cost of its treatment is considerable. Accordingly, the number of weight management treatments has increased to meet this growing public health challenge. Unfortunately, insufficient participation in weight management treatment, namely low adherence and high attrition, often impede the effectiveness of these programs. Although the barriers associated with inadequate adherence and elevated rates of attrition are documented, there is a dearth of research on the predictors of the …

An Examination Of Weight, Weight Bias, And Health Care Utilization And Attitudes Among Emerging Adults, Jessica M. Mccauley

Theses and Dissertations

Individuals with overweight/obesity have been found to exhibit more negative attitudes toward health care and disproportionate rates of health care delay and avoidance, compared to their healthy weight peers. The present study sought to examine potential mechanisms through which weight status influences health care utilization and attitudes. Six hundred and thirty-three students completed a questionnaire measuring weight status, perceived weight bias, patient-provider relationship, and health care utilization and attitudes. Although the majority of the paths in the proposed theoretical mediation model were supported by the present findings, there was no support for the anticipated link between perceived weight bias and …

Socioeconomic Status And Weight Loss Behaviors, Hannah Seward

Theses and Dissertations

In the United States and many other countries, obesity is viewed as a public health crisis that must be handled. Many social and individual solutions to the problem are proposed in research and policy. On an individual level, many Americans try to get rid of their fat with a multitude of weight loss practices as part of a healthy lifestyle. Obesity rates, feelings towards fatness, and weight control behaviors are significantly affected by a number of sociocultural factors. In this project I explore the relationship between the desire to lose weight and weight control practices with income. Using data from …

The Effect Of Obesity On Il-1Β, Il-1ra, And Leptin Following Acute Mental Stress, Heather Caslin

Theses and Dissertations

Research regarding the development of cardiovascular disease (CVD) is important because CVD is the leading cause of death in the United States (US) and many countries abroad. Risk factors, such as obesity and psychological stress, should be studied in order to understand contributing factors for CVD and the cellular mechanisms which link risk factors with the development of disease. Specifically, the combined influence of multiple risk factors on inflammation is of interest because many individuals have more than one risk factor, which additively increases an individual’s risk for CVD. Obesity is already characterized by disordered inflammation, which suggests that the …

Text Messaging As Adjunct To Community Based Weight Management Program, Claudia Bouhaidar

Theses and Dissertations

Obesity ascending rates are still a public health priority. The primary aim of the study was to evaluate the effect of tailored text messages on body weight change in overweight and obese adults in a community based weight management program. A secondary aim was to detect behavioral changes in the same population. The study design was quasi-experimental with pre and posttest analysis, conducted over 12 weeks. A total of 28 participants were included in the analysis. Body weight, eating behaviors, exercise and nutrition self-efficacy, attitude toward mobile technology, social support and physical activity were assessed at baseline and at 12 …

Ecological Momentary Assessment And Time-Varying Factors Associated With Eating And Physical Activity, Amy Jeffers

Theses and Dissertations

The obesity epidemic is a significant problem in the United States. It is well established that lifestyle factors, such as unhealthy eating and physical inactivity, are key contributors. These causes are generally voluntary activities and it is important to examine health decision-making with respect to these behaviors. The current study examined time-varying factors of stress and mood and their relationship with healthy eating and physical activity in a sample of undergrads (N = 26). Ecological momentary assessment via one's cell phone was used to collect multiple measurements over six days. Positive mood was found to follow physical activity episodes for …

On The Genetic And Environmental Associations Between Body Composition, Depression Symptoms And Smoking Behavior., Roseann Peterson

Theses and Dissertations

Obesity is a serious public health crisis and recent estimates of its incidence are the highest in United States history, with 35% and 17% of American adults and children affected, respectively. The clinical definition of adult obesity is operationalized as a body mass index (BMI) greater than 30 kg/m2. Although the prevalence of common obesity has increased dramatically over the past 30 years–largely thought to be due to changes in the environment, such as high calorie diets and sedentary lifestyles—twin and family studies have shown consistently that relative body weight is under considerable genetic influence in both children and adults, …

Parental And Family Predictors Of Adolescent Weight Loss And Health Change In A Multidisciplinary Obesity Intervention, Jacqueline Woods

Theses and Dissertations

The home environment, parental health attitudes, and parental diet and exercise behaviors have been associated with childhood obesity. The current study utilized a family systems framework to examine the effect of these variables on weight and health changes in a primarily Black sample of 530 parent-adolescent dyads enrolled in a multidisciplinary weight loss intervention. Parent-reported psychosocial variables and demographic information were used to test models predicting changes in adolescents’ body mass index, cholesterol, and percentage body fat over the first six months of the intervention. The effect of parent participation in a psycho-education parent group on adolescent health outcomes was …

Adolescent Girls' Experience Of Binge And Loss Of Control Eating, Allison Palmberg

Theses and Dissertations

The current investigation used qualitative methodology to examine adolescent girls’ perceptions of control over their eating, as well as triggers, and consequences of binge and related eating behaviors. Focus groups were completed with 19 adolescent girls (aged 13-17, 58% African American, 41% White) who endorsed the behaviors. Responses to focus group questions were qualitatively analyzed using a grounded theory approach and constant comparison coding. Results reflected a fundamental lack of awareness of the loss of control (LOC) eating behaviors. Yet, the data did reflect a central theme of the need to affirm independence and autonomy through eating behaviors via three …

Association Between Obesity And Depression And Anxiety Disorders: Results From The 2008 National Health Interview Survey, Monica Gaidhane

Theses and Dissertations

Introduction: Obesity is one of the most important medical problems in the U.S. and is considered to be an epidemic with over 30% of the population being obese. Obesity is associated with increased risk of hypertension, diabetes, cardiovascular diseases, certain cancers and a shorter life expectancy. Recent studies have shown that higher BMI levels are also significantly associated with several lifetime mental disorders such as major depressive disorder, anxiety disorders as well as panic attacks and panic disorders. Purpose: The purpose of this study was to quantify the extent to which higher BMI increased the likelihood of Depression, Anxiety Disorder …

The Effects Of Obesity And Surgically-Induced Weight Loss On Exercise Ventilation: Influence Of Central Adiposity And Serum Leptin, Jeffrey Herrick

Theses and Dissertations

Truncal adiposity impairs ventilation in obese adults by altering normal ventilatory mechanics. Leptin, an inflammatory adipocytokine, is elevated in obesity and has been shown to alter ventilatory responses to exercise. Leptin’s bioavailability appears to be regulated by its soluble receptor (LRe), which is reduced in obesity. Roux-en-Y gastric bypass surgery (RYGBS) is a weight loss intervention that reduces total fat mass and improves several obesity related co-morbidities including pulmonary dysfunction. The purpose of this study was to first evaluate the differences between ventilatory responses to carbon dioxide (VE/VCO2 slope) during progressive treadmill walking in morbidly obese and normal weight females. …

Time Course Of Vascular Function Changes Following An Acute Maximal Exercise Bout In Obese And Normal Weight Males, R. Lee Franco

Theses and Dissertations

One of the earliest sub-clinical stages associated with atherosclerosis is endothelial dysfunction (ED), which has been shown to predict future cardiovascular events. Chronic exercise is thought to improve endothelium-dependent vasodilation; however, few studies have evaluated the effects of acute exercise on vascular function (VF). Moreover, studies evaluating ED following an exercise training program lack a standardized time frame in which to measure VF. Although most studies require subjects to abstain from exercise for 24 hours prior to any VF measure, no study to date has assessed VF longer than 24 hours after the cessation of exercise. Additionally, no studies have …

Obesity, Adiposity, And Satiety In Mouse Models Of Smith-Magenis Syndrome And Dup(17)(P11.2) Syndrome, Brooke Burns

Theses and Dissertations

Smith-Magenis syndrome (SMS) is a complex disorder caused by haploinsufficiency of RAI1 and characterized by sleep disturbances, behavioral abnormalities, mental retardation, and obesity in teens and adults. Rai1+/- mice are obese after 20 weeks. Dup(17)(p11.2) syndrome is a complex disorder associated with overexpression of RAI1. A transgenic mouse model of dup(17)(p11.2) syndrome overexpresses Rai1 and results in a mouse that is growth delayed. In order to characterize the obese phenotypes of mouse models of SMS and the role of RAI1 in obesity, daily food intake and serum levels of insulin, glucose, PPY, and leptin were measured; adiposity was studied by …

Binge Eating In Ethnically Diverse Obese Adolescents, Clarice K. Gerke

Theses and Dissertations

Rates of pediatric obesity in America are reaching epidemic proportions. Studies using both community and treatment-seeking samples of obese adolescents indicate that a subset engage in binge eating behaviors. This study investigated the prevalence and severity of binge eating behaviors among 86 primarily African American 11 to 17 year old adolescents seeking outpatient treatment for obesity. This study also examined the associations of stressful experiences (specifically, weight-related teasing, trauma, and daily hassles) with binge eating, as well as potential mediators and moderators of these relationships. Twenty-eight percent of the sample reported at least one episode of binge eating in the …

Assessing The Relationship Between Socioeconomic Variables And Risk Of Overweight Among Children 6 Years Of Age, Marilyn Cochon Batan

Theses and Dissertations

Background: The percentage of overweight children has tripled in the last thirty years. Inconsistent findings are published regarding the relationship between socioeconomic variables and being overweight in childhood.Objective: To determine whether socioeconomic variables are associated with risk of being overweight among six year olds. Methods: Six year olds with BMI data were selected from the National Survey of Children's Health (n=4,362). Variables were coded and a low socioeconomic index was created. Using population weights, descriptive statistics were generated and regression was utilized to assess the relationship between socioeconomic variables and being 'at risk' for overweight. Socioeconomic variables were also compared …

Association Between The Frequency Of Physical Education Classes And The Prevalence Of Overweight/Obesity In Adolescents, Collin N. Rice

Theses and Dissertations

Background/Objective: Overweight and obesity has been steadily on the rise in the United States for all groups. The prevalence of obesity for adolescents has tripled since 1980. The purpose of this study is to determine an association between the frequency of physical education classes and the prevalence of overweight/obesity in adolescents in the United States.Methods: This was a cross-sectional study that used the 2001 Youth Risk Behavior Survey (YRBS) of the Center for Disease Control. The outcome variable for the study was Body Mass Index (BMI). A BMI of 25 or greater was considered overweight or obese. The main independent …

Obesity And Health Status Among Urban Vs. Suburban Elderly In Philadelphia And Surrounding Counties, Ockidde Dufayne Harris

Theses and Dissertations

Obesity is a dangerous health condition affecting approximately 30% of all Americans and can be attributed to 300,000 deaths a year. Obesity has been found to disproportionately affect Blacks, Latinos, and those with lower SES. Although obesity is a problem for all age groups, its prevalence is highest among those 60-74 years of age. Studies have shown that there is an association between obesity and chronic conditions such as cardiovascular disease, arthritis, cancers, and type-2 diabetes. According to the Centers for Disease Control, chronic health conditions affect 80% of all elderly persons, many times limiting function and decreasing quality of …

Body Image And Attitudes Toward Obesity In College Students, Sarah Rebecca Goodwin

Theses and Dissertations

The current study was conducted in order to examine the impact of ethnicity on gender differences in body type preferences and perceptions and add to the literature examining racial differences in body type preferences and perceptions. The current study was an expansion of one by Gipson et al conducted at a historically Black university in 2004, in which responses and BMI measurements of 191 college students were examined for associations between BMI and gender, and body image and attitudes toward obesity. For the current study the sample of 176 college students enrolled at Virginia Commonwealth University, an ethnically diverse institution, …
