Motivational And Physiological Dysregulation Due To Development And Onset Of Obesity Via Melanocortin 4 Receptor +/- Haploinsufficiency, Alex Steiner
Theses and Dissertations
Obesity is one of the leading most health risks around the world, being especially problematic in the United States. A combination of high-fat diets and genetic abnormalities are to blame for the ever-growing number of obese individuals.
Melanocortin 4 receptors are vital for regulating energy expenditure and feeding behaviors; mutations of the receptors have been found to be the leading monogenetic cause of obesity. Using MC4R +/- haploinsufficient rats being fed a range of dietary fat, we investigated the physiological and motivational differences using a locomotor task, an operant task with fixed and progressive ratios, as well as a distraction …
The Impact Of Diet And Psychosocial Factors Post Bariatric Surgery, Eva Rani Panigrahi
The Impact Of Diet And Psychosocial Factors Post Bariatric Surgery, Eva Rani Panigrahi
Psychology Theses & Dissertations
Bariatric surgery is a medical procedure that has been found to be an effective option for weight loss. Despite the benefits of bariatric surgery, little is known about the psychosocial factors that may impact weight outcome. The present study attempted to examine patients’ level of perceived stress, depressed mood, and diet, and the association of these factors with percent weight loss in the first 6-months after surgery. Eighty patients completed pre- and 6-months post-operative depressed mood assessment (Patient Quality Health Questionnaire – 7 [PHQ-7]), a perceived stress measure (Cohen’s Perceived Stress Scale – 10 [PSS-10]), and dietary measures (Block Dietary …
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
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 …
Associations Among Parenting Style And Parental Feeding Practices On Adolescent Self-Efficacy For Diet And Obesity In African American Adolescents, Haylee Loncar
Theses and Dissertations
Previous literature has demonstrated relationships between parenting factors and child health. However, few studies have investigated such associations in African American and adolescent samples. The proposed study aimed to investigate the relationships between parenting factors (parenting style and parental feeding practices), and adolescent self-efficacy for diet, and adolescent body mass index (BMI) in African American families. Baseline data were collected from 241 African American parent- adolescent dyads enrolled in the Families Improving Together (FIT) for Weight Loss trial. Adolescents self-reported their perceptions of their caregiver’s parenting style and feeding practices, as well as perceptions of their own self-efficacy for diet. …

A Survey Of Providers And Patients Assessing The Need For And Use Of Prevention Practitioners To Combat Obesity In The Primary Care Setting, Amanda R. Lyons
DNP Projects
Purpose: The overall aim of this project was to gather information from two groups of stakeholders, providers and patients, on the feasibility of implementing prevention practitioners in the primary care system to address overweight and obesity.
Methods: This study utilized a quantitative descriptive design through the use of electronic surveys. Provider surveys were explained and presented during a monthly provider meeting. Patient flyers were posted in exam rooms and surveys were accessible through a provided link and QR code.
Results: Providers (N=10) agreed that they saw a need for the use of a prevention practitioner (Mean=4.44, SD=.88) as well as …
Exploring Obesity, Adhd Severity, And Disordered Eating Behavior Among College Students, Carolina Rozario
Exploring Obesity, Adhd Severity, And Disordered Eating Behavior Among College Students, Carolina Rozario
Dissertations and Theses
Obesity is a global epidemic because of the potential health risks. There is evidence that many obese individuals manifest persistent ADHD symptoms, and that both disorders increase risk for binge eating. Nevertheless, how obesity and ADHD may increase risk for binge eating work is unclear. Neuropsychological deficits are common to all disorders and may help to explain the relations observed. The aim of this study was to explore whether neuropsychological dysfunction, especially inhibitory control weaknesses, moderate the association between greater BMI and more severe ADHD and disordered eating behaviors. Thirty-nine undergraduate college students (27 females; Mean age = 20.77, SD …
The Association Between Body Esteem And Post-Operative Outcomes In Adult Weight-Loss Surgery Patients, Jennifer Rohr Swetkowski
The Association Between Body Esteem And Post-Operative Outcomes In Adult Weight-Loss Surgery Patients, Jennifer Rohr Swetkowski
PCOM Psychology Dissertations
Bariatric surgery (weight-loss surgery) remains the most effective long-term treatment for obesity, resulting in improved obesity-related comorbidities and increased life expectancy. There remains, however, a limited understanding of predictors and patientlevel factors associated with insufficient weight loss and psychological dysfunction. Body esteem, or feelings of self-worth about one’s body and appearance, is a significant concern for individuals undergoing weight-loss surgery, although the relationship between body esteem and weight loss is complex. Indeed, there is a subset of patients who experience suboptimal weight loss and poor psychological outcomes after undergoing bariatric surgery. This retrospective, longitudinal study examined the relationship between pre-operative …
Depression Screening For Bariatric Surgical Patients, Cova Teresa Stidham
Depression Screening For Bariatric Surgical Patients, Cova Teresa Stidham
Walden Dissertations and Doctoral Studies
Obesity in the United States has increased to epidemic numbers over the last decade. Practitioners need to reverse the trend. To address the problem of depression in obesity, a practice guideline from a bariatric clinic for under-served populations was proposed to an expert panel. The Spell Out on First Use (PHQ-9) screening is a valid and reliable self-screening tool to assist the practitioner in determining the level of depression if any. The PHQ-9 has nine questions. No formal screening existed at the bariatric clinic, and the practice guideline (with algorithm and revised workflow) was proposed for use at the clinic. …
