Human Movement Studies & Special Education Faculty Publications

Polychlorinated biphenyls (PCBs) are persistent environmental organic pollutants known to have detrimental health effects. Using a mouse model, we previously demonstrated that PCB126 exposure before and during pregnancy and throughout the perinatal period adversely affected offspring glucose tolerance and/or body composition profiles. The purpose of this study was to investigate the glucose tolerance and body composition of offspring born to dams exposed to PCB126 during the nursing period only. Female ICR mice were bred, and half of the dams were exposed to either vehicle (safflower oil) or 1 µmole PCB126 per kg of body weight via oral gavage on postnatal …

Improving Screen Time Review And Adherence To Age-Based Limits In A Fqhc, Erin K. Milner

DNP Projects

Background: Children in the US spend an average of 7.5 hours a day in front of a screen, well above the recommended 2 hours per day for entertainment. Screen time of greater than 3 hours per day is associated with higher body mass indices and insulin resistance that can lead to type 2 diabetes. Providers should review and reinforce age-appropriate screen time guidelines at well-child visits. Screen time education and behavior contracts can be used to facilitate age-appropriate screen time.

Project Goals:

1. To implement screen time education and behavior contracts in a pediatric population in a federally qualified health center …

Factors That Predict Weight Loss Success Differ By Diet Intervention Type, Jordan Losavio, Michael J. Keenan, Elizabeth A. Gollub, Heidi J. Silver

Faculty Publications

Background: Many types of diet intervention can achieve negative energy balance and successful weight loss in persons with obesity. However, within any dietary strategy, there is large inter-individual variation in the weight loss response. The aim of this study is to determine factors that predict weight loss success for diet interventions that vary by macronutrient and caloric composition. Methods: Participants with BMI 30.0 to 49.9 kg/m2 self-selected one of three diet intervention trials for weight loss: low carbohydrate (LOW CHO), low fat (LOW FAT), or low calorie (LOW KCAL). Multivariable regression models were developed to determine the significance of predictor …

Effects Of Ketone Bodies On Energy Expenditure, Substrate Utilization, And Energy Intake In Humans, Rodrigo Fernández-Verdejo, Jacob T. Mey, Eric Ravussin

Division of Basic Science Faculty Publications

The potential of ketogenic approaches to regulate energy balance has recently gained attention since ketones may influence both energy expenditure and energy intake. In this narrative review, we summarized the most relevant evidence about the role of ketosis on energy expenditure, substrate utilization, and energy intake in humans. We considered different strategies to induce ketosis, such as fasting, dietary manipulation, and exogenous ketone sources. In general, ketosis does not have a major influence on energy expenditure but promotes a shift in substrate utilization towards ketone body oxidation. The strategies to induce ketosis by reduction of dietary carbohydrate availability (e.g., ketogenic …

Adipose Tissue Expansion In Obesity, Health, And Disease, Ursula White

Clinical Research Faculty Publications

White adipose tissue (WAT) expands under physiological conditions via an increase in adipocyte size (hypertrophy) and/or number (hyperplasia; adipogenesis), and the ability of WAT to expand to accommodate energy demands is a significant determinant of metabolic health status. Obesity is associated with impaired WAT expansion and remodeling, which results in the deposition of lipids to other non-adipose organs, leading to metabolic derangements. Although increased hyperplasia has been implicated as a cornerstone in promoting healthy WAT expansion, recent developments suggest that the role of adipogenesis as a contributing factor in the transition from impaired subcutaneous WAT expansion to impaired metabolic health …

Investigating The Association Between Adverse Childhood Experiences And Obesity While Considering Race, Ethnicity, Sex, And Sexual Orientation, Mariama Ceesay

Legacy Theses & Dissertations (2009 - 2024)

AbstractObesity is a chronic disease that plagues about 34% of the world population and rising (CDC,2023). Obesity develops over time due to lifestyle factors, biological factors, and the environment. Life course epidemiology approaches understanding the etiology of obesity by pinpointing how particular events in a lifetime can facilitate later life obesity. One emerging important early life factor that may influence adult obesity risk is adverse childhood experiences (ACEs). Rates of ACEs are higher in sexual minorities, women, and nonwhite individuals (Hughes et al., 2022). Furthermore, the rate of obesity is higher in women and nonwhite communities (CDC,2023). Knowing this information, …

Fork It, Kylee Pipgrass

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Obesity prevalence is at an alarmingly high rate within the United States, but especially in rural areas of Kentucky. Obesity can lead to a variety of negative physical health outcomes including heart disease, diabetes, stroke, and some cancers. There are also mental disorders associated with obesity through mechanisms such as weight stigma and self-perception. Similar to obesity rates, prevalence and mortality associated of these health outcomes are also seen at disproportionately higher rates in rural, Appalachian Kentucky. Causes for increased obesity and obesity related consequences include some genetic factors as well as behavioral factors like physical inactivity, poor diet, stress, …

An Analysis On How Housing Status Influences The Gut-Brain-Axis For Populations In And Around The Skid Row Area Of Los Angeles, California, Mauricio Guzman

Pitzer Senior Theses

Over recent years, the “microbiota-gut-brain axis” (MGBA) has garnered significant attention in the scientific community. Specifically, perturbations of the MGBA via stress and dietary intake have been linked to a wide-range of diseases including gastrointestinal diseases, metabolic diseases, mood disorders, and cognitive diseases. However, most studies have been solely conducted on mice models and have yet to consider the more complex, intricate systems that impact the human body. In addition, researchers have yet to consider the populations who may be most susceptible to chronic stress and negative dietary outcomes. Drawing from the fields of medical sociology, non-invasive human biology, and …

An Association Of The Transgenerational Implications Of Redlining And Obesity On Pediatric Type Ii Diabetes, Carlin Dexter Nelson

Walden Dissertations and Doctoral Studies

s the prevalence and incidence of childhood obesity has increased, so has the number of cases of pediatric Type 2 diabetes mellitus (T2DM). Although made unconstitutional in 1968, the transgenerational implications of redlining can be observed in disinvestments resulting in neighborhood detraction. Utilizing the 2019–2020 National Children’s Health Survey, the purpose of the study was to evaluate the relationship between obesity, T2DM, and neighborhood detraction elements as well as assessed indicators of T2DM in non-institutionalized children 6 through17 years of age (N = 34,725).

Effects Of Constant Load Exercise On Oxygen Consumption And Knee Joint Mechanics In Young Adults, Mariana Victoria Jacobs

Theses and Dissertations--Kinesiology and Health Promotion

The rate of obesity and its adverse health consequences have continued to rise in the past several decades. Aerobic constant load exercise is recommended to reduce excess body mass, however the effects of constant load exercise on oxygen consumption (VO2) and knee joint mechanics are inconsistent when varying weight-status strategies are employed. The purpose of this study was to assess the influence of different weight classification strategies on VO2 and knee joint mechanics during constant load exercise. Participants walked on an instrumented treadmill at a self-selected speed for 30-minutes while gait mechanics and VO2 measures were determined. Between-group differences were …

Investigating The Relationship Between Metabolic Reprogramming And Peripheral Cd4+ T-Cell Inflammation In Human Type 2 Diabetes Pathogenesis, Gabriella Kalantar

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Chronic, low-grade systemic inflammation rises in obesity and promotes type 2 diabetes (T2D). Circulating immune cells are key indicators of obesity and T2D pathogenesis. T cells outnumber monocytes, in blood, suggesting that T cells might fuel peripheral inflammation in obesity/T2D. Our lab’s work supports this idea by identification of a Th17 cytokine profile in T2D from T-cell stimulated peripheral blood mononuclear cells. Work described herein further supported this work by demonstrating that T cells dominate peripheral inflammation over monocytes across the spectrum of obesity and glycemic control. Our lab has also recently shown that inflammation changes during prediabetes (preT2D), identified …

Quality Improvement Project To Assist In Implementation Of Prediabetes Screen Protocol, Kyai Forney

Doctoral Projects

Prediabetes is a reversible condition that causes blood glucose levels to be higher than normal, but not high enough to be diagnosed as type 2 diabetes. When one has prediabetes, the cells in the body do not respond normally to insulin, and insulin acts like a key to letting blood sugar into cells to use energy. The pancreas produces insulin to try to get the cells to respond, but eventually, the pancreas has a challenging time keeping up, and the blood sugar level rises causing prediabetes (Lehrman, 2021). A person can have prediabetes for years with no obvious symptoms, so …

Associations Between Socioecological Factors And Breastfeeding Duration Among Obese Mothers In Mississippi, Maria Mercedes Miranda Porter

Walden Dissertations and Doctoral Studies

There is a growing obesity pandemic in the United States. Low breastfeeding duration rates and socioecological factors lead to obesity in the most southern states. Overweight and obese breastfeeding mothers have not been primarily studied. There is mixed information regarding duration of breastfeeding, BMI, and heart health, as well as a lack of quantitative analyses involving reducing obesity rates in mother-child dyads. The purpose of this quantitative cross-sectional study was to investigate whether there were any associations between breastfeeding duration and BMI, heart health problems, breastfeeding support, and eating and exercise among Mississippi overweight and obese postpartum women based on …

Non-Pharmaceutical Symptom Management In Patients With Pcos, Allison Stern

Capstone Showcase

Polycystic Ovarian Syndrome (PCOS) is a relatively common diagnosis among biological females. There are many variations of presentations among patients with PCOS that require an individualized and tailored treatment plan for symptom management. Although there are pharmaceutical medications that can be used for PCOS symptoms, some patients’ symptoms might not be fully managed, or they might prefer to focus on non-pharmaceutical options for their symptoms instead. Therefore, it is important for clinicians to be familiar with alternatives to the mainstay of pharmaceutical treatment.

Night Bites: The Relationship Between Sleep Quality, Binge Eating, And Night Eating, Mccall Schruff

Electronic Theses and Dissertations

Obesity is a chronic disease and classified as a global epidemic. Its incidence has rapidly increased worldwide, particularly within the United States where associated adverse health consequences have led to substantial increases in premature mortality, health-care utilization, and spending. Given the biopsychosocial nature of obesity, it can be considered a preventable health-risk that is a major public health concern. Associated risk factors, such as insufficient quality and quantity of sleep, binge eating, and night eating, could worsen health outcomes, as research suggests these symptoms rarely occur in isolation and are more frequent in individuals with higher body mass index. In …

All Works

Background: Growing evidence supports the role of gut microbiota in obesity, yet exact associations remain largely unknown. Specifically, very little is known about this association in the Emirati population. Methods: We explored differences in gut microbiota composition, particularly the Firmicutes/Bacteroidetes (F/B) ratio, between 43 obese and 31 lean adult Emirate counterparts, and its association with obesity markers, by using V3-V4 regions of 16 S ribosomal RNA gene sequencing data. Furthermore, we collected anthropometric and biochemical data. Results: The two major phyla in obese and lean groups were Firmicutes and Bacteroidetes. We observed a significantly lower alpha diversity (Shannon index) in …

Bilirubin Levels Are Negatively Correlated With Adiposity In Obese Men And Women, And Its Catabolized Product, Urobilin, Is Positively Associated With Insulin Resistance, Zachary A. Kipp, Mei Xu, Evelyn A. Bates, Wang-Hsin Lee, Philip A. Kern, Terry D. Hinds Jr.

Markey Cancer Center Faculty Publications

Bilirubin levels in obese humans and rodents have been shown to be lower than in their lean counterparts. Some studies have proposed that the glucuronyl UGT1A1 enzyme that clears bilirubin from the blood increases in the liver with obesity. UGT1A1 clearance of bilirubin allows more conjugated bilirubin to enter the intestine, where it is catabolized into urobilin, which can be then absorbed via the hepatic portal vein. We hypothesized that when bilirubin levels are decreased, the urobilin increases in the plasma of obese humans, as compared to lean humans. To test this, we measured plasma levels of bilirubin and urobilin, …

Several population studies have observed lower serum bilirubin levels in patients with non-alcoholic fatty liver disease (NAFLD). Yet, treatments to target this metabolic phenotype have not been explored. Therefore, we designed an N-Acetylgalactosamine (GalNAc) labeled RNAi to target the enzyme that clears bilirubin from the blood, the UGT1A1 glucuronyl enzyme (GNUR). In this study, male C57BL/6J mice were fed a high-fat diet (HFD, 60%) for 30 weeks to induce NAFLD and were treated subcutaneously with GNUR or sham (CTRL) once weekly for six weeks while continuing the HFD. The results show that GNUR treatments significantly raised plasma bilirubin levels and …

Associations Between Substance Use And Obesity Among Native American Adolescents, Joseph Jude Janosky

Walden Dissertations and Doctoral Studies

Obesity and substance use are two significant public health issues among Native American adolescents. Despite much evidence linking obesity and substance use during adolescence to several long-term health conditions and increased morbidity and mortality, evidence describing the relationship between current substance use and obesity among Native American adolescents is lacking. The purpose of this quantitative study was to investigate associations between current substance use – specifically alcohol, marijuana, and tobacco products – and obesity among Native American high school students, when adjusted for sex, soda consumption, and physical activity. Rosenstock’s health belief model served as the theoretical foundation for this …
