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 …

The Moderating Effects Of Parenting Factors And Perceived Stress On African American Adolescent Weight Related Outcomes, Colby Kipp

Theses and Dissertations

African American adolescents experience a higher prevalence of obesity than nonminorities with approximately 40% being overweight or obese. Chronic stress, both among parents and adolescents, may be important to consider when assessing the factors that influence adolescent weight status. Baseline data were collected from one hundred forty eight African American adolescents (M_age = 12.93, SD = 1.75; M_BMI% = 96.7, SD = 3.90) and their caregivers (M_age = 44.5, SD = 8.6; M_BMI = 37.63, SD = 8.21) enrolled in the Families Improving Together (FIT) for Weight Loss trial. Adolescents self-reported their perceptions of …

The Role Of A Community-Driven, Structured Exercise Program On Children's And Adolescent's Quality Of Life, Padgett Singley Powe

Senior Theses

Childhood obesity is a long-standing epidemic in the United States as of 2020, and the problem is continuing to worsen. Childhood obesity has been shown to have many unhealthy effects, such as increasing prevalence of cardiovascular disease, depression, and social anxiety, which all can contribute to a worsened quality of life. Research suggests that summer is the most critical time period to combat childhood obesity is because children’s lives are less structured over the summer, which can lead to increased unhealthy behaviors, obesity, and a decrease in quality of life. The current study, the Skybrook Swim Team Study, aimed to …

Association Of Body Mass Index Genetic Risk Markers With Body Composition During Adolescence, Brice A. Smoker

Senior Theses

Background. Obesity affects nearly a fifth of all children in the United States and is a common risk factor for numerous chronic diseases. Many risk factors contribute to obesity, including race and genetics. Obesity is partially heritable, and many genetic loci have been identified as being associated with body mass index (BMI) in adults. Some of these loci have also been associated with childhood BMI, with effects strengthening with age. A previous genome-wide association study (GWAS) identified five single nucleotide polymorphisms (SNPs) associated with changes in BMI in children aged 1 – 17 years.

Purpose. The purpose of the current …

Gestational Infections And Obesity: Implications For Intellectual Disability Risk, Maggie S. J. Mccarter

Theses and Dissertations

Maternal body weight, measured as Body Mass Index (BMI) and infection during pregnancy are established risk factors of multiple adverse birth outcomes that are also associated with intellectual disability (ID) in children, but little is known of the interaction of these two factors. This retrospective cohort study sought to explore whether BMI is an effect modifier in the association between maternal infection during pregnancy and ID of the child, and to make comparisons between categories of gestational infection. The study sample (n= 124,047 after exclusion) was derived from Medicaid administrative data. After preliminary analysis of interaction, stratified logistic regression analysis …

Macrophages And Associated Inflammation Differentially Impact Obesity, Colorectal Cancer And Obesity-Enhanced Colorectal Cancer, Jackie Bader

Theses and Dissertations

Colorectal Cancer (CRC) is the third-most common malignancy for men or women, with chronic inflammation considered as a primary risk factor. Obesity is also considered a chronic inflammatory disease and is associated with increased CRC incidence. Further, obesity and CRC occur in men and women differently with the highest incidence of either disease found in men, suggesting that female sex hormones may play a protective role in inflammatory diseases. Macrophages can promote inflammation and are a driving force in obesity-associated metabolic dysfunction. Conversely, macrophages also contribute to pro-tumoral responses including, proliferation, angiogenesis and tissue remodeling. This heterogeneity of macrophage behavior …

The Contribution Of Adipose Tissue From Ovariectomized Mice To Colon Cancer, Meredith Smith Carson

Theses and Dissertations

Obesity is considered a major public health concern worldwide due to the increased incidences of metabolic dysfunction and cancer risk. The obese state is, in part, attributable to the overconsumption of calorie-dense foods commonly seen in a standard Western diet, which aids in the progression of chronic, lowgrade inflammation. The role of estrogen varies depending on menopausal status, where estrogen deficiency coupled with increased visceral fat associated with post-menopause leads to increased secretions of pro-inflammatory adipokines and cytokines. However, the presence of estrogen in a premenopausal state has been shown to attenuate the pro-inflammatory response, which has been demonstrated when …

The Plant-Based And Soul-Full Study (Pass): Examining How Owners Of Local Vegan Soul Food Restaurants Promote The Consumption Of Vegan Foods In The African American Community, Anthony Crimarco

Theses and Dissertations

Background: Obesity remains a prevalent public health epidemic and African American (AA) adults are disproportionately affected by obesity more than any other ethnic group. There are also disparities in obesity by location, with the South having the highest rates compared to other geographic regions in the United States. Addressing poor dietary habits is important for improving obesity rates among AAs, but there has been limited research that has focused on specifically developing culturally-tailored interventions. With a recent number of soul food restaurants serving exclusively vegan meals opening up across the country to appeal to AAs and others interested in eating …

Relationships Of Chronotype, Social Jetlag, Sleep, Physical Activity And Diet With Mood, Perceived Stress, Obesity, Blood Pressure And Prostate Cancer, Daria M. Mcmahon

Theses and Dissertations

Background: Chronotype, social jetlag, poor sleep, proinflammatory diet, and low physical activity have been associated with increased risk of chronic diseases: obesity, diabetes, cardiovascular disease, depression and cancer. Yet the relationships between these factors have not been extensively investigated in prospective studies.

Methods: Two studies were conducted. The first study followed 390 healthy men and women ages 21-35 for two years. Social jetlag [SJL] and sleep measures (total sleep time [TST], sleep onset latency [SOL], wake after sleep onset [WASO]), sleep efficiency [SE]), were derived from physical activity personal (armband) monitoring. The participants wore the armband for 4-10 …

Influence Of Built Environment On Physical Activity Outcomes Among African Americans In Community-Based Obesity Intervention Studies, Amanda Sue Thomas

Theses and Dissertations

More than sixty-five percent of people in the U.S. are considered overweight or obese. African-Americans in the U.S. have a higher risk of obesity than any other racial group. One way to reduce this statistic is physical activity. Recreational green spaces (parks) can serve as an avenue to complete the 150 min/wk of recommended physical activity for adults by the ACSM. Data from SISTAS and HEALS interventions, that recruited overweight/obese African-Americans from Columbia and Florence, SC, was used to assess the association of recreational green space (parks) around a residence and physical activity. Physical activity measures of RAPA questionnaire (self-report), …

Refinement And Pilot Testing Social Networks For Encouraging Healthy Behaviors: The Social Pounds Off Digitally (Social Pod) Study, Sarah B. Hales

Theses and Dissertations

Currently about 71% of adults in the US are considered overweight or obese. Overweight and obesity are associated with higher risk of developing many chronic diseases; however, health risks associated with overweight and obesity can be reduced by as little as a 3% to 5% reduction in weight. Mobile health (mHealth) has shown promise as a way to deliver weight loss interventions, yet maintaining participant engagement over time has been a challenge. The purpose of this study was to develop, refine, and pilot test the Social Pounds Off Digitally (POD) Android app for personalized health monitoring and interaction; revise the …

Periodontal Microorganisms, Obesity, Chronic Inflammation, And Type 1 Diabetes, Georges Joseph Nahhas

Theses and Dissertations

Periodontal disease is a low-grade chronic inflammation in the tissues surrounding the teeth caused by multiple, mostly gram-negative pathogens. It is associated with diabetes, obesity, and chronic inflammation. The specific roles that periodontal microorganism play in these conditions are not well-studied. Hereby, we explored how periodontal bacteria from sub gingival plaque clustered in youth with and without type 1 diabetes, and how such patterns related to body-mass-index percentile (BMI percentile), C-reactive protein (CRP) and adiponectin. Cross-sectional data were collected from 105 youth with type 1 diabetes and 71 without diabetes. Participants were between 12 and 19 years of age receiving …

Exploring The Association Between Depression And Obesity Among Alzheimer's Patients, Stephanie Clugstone

Theses and Dissertations

Alzheimer’s disease (AD) is a neurological disorder that affects elderly individuals, and is becoming an increasing concern among the aging population of the world. Due to the projected increase in incidence of AD, modifiable risk factors such as depression and obesity should be evaluated, as prevention is the only current option. This study aimed to determine the prevalence of obesity and depression among AD patients, and to evaluate the association between depression and obesity. Patients were chosen from a subset of the South Carolina Alzheimer’s disease registry, which included information about weight status and depression, as well as several other …

High Fat Diet Induced Obesity In A Mouse Model For Colorectal Cancer, Kennerly Clinton Patrick

Theses and Dissertations

Obesity is widely correlated with the incidence of colorectal cancer (CRC). The exact mechanisms that link obesity to CRC risk have not yet been fully established, and only a limited number of animal models are available to study pathways involved in obesity-related colon carcinogenesis. The objective of this study was to determine the influence of HFD-induced obesity on AOM/DSS-mediated colorectal tumorigenesis, tumor proliferation, and symptom severity. Male C57BL/6 mice were fed a novel high fat diet, designed to mimic the standard American diet (12 % saturated fat & 28 % unsaturated fat), at 4 weeks of age until 16 weeks …

Linking Obesity To Colorectal Cancer: Recent Insights Into Plausible Biological Mechanisms, Catherine Guffey

Theses and Dissertations

Obesity has emerged as a leading environmental risk factor for the development of CRC. However, the mechanisms underlying this relationship have not yet been fully explained. Recent literature has focused on 1) inflammatory processes, 2) adipokines, and 3) estrogen. Obesity-enhanced inflammation is largely orchestrated by increases in adipose tissue macrophages leading to the secretion of TNF-alpha, MCP-1, and IL-6, all of which are linked to CRC. Adiponectin is decreased with obesity and has been reported to be negatively associated with CRC, while leptin, which is increased, is positively associated with the disease. Estrogen has been shown to influence CRC, although …

Bmi At Diagnosis And Its Association With Markers Of Hiv Disease Progression And Cardiovascular Disease Risk., Kelly Deshon Johnson

Theses and Dissertations

Highly active antiretroviral treatment (HAART) has transformed the state of human immunodeficiency virus (HIV) from acute to chronic. As a result, the long-term effect of HAART has caused weight gain among HIV-infected individuals, leading to an increased prevalence of overweight and obesity. Increased Body Mass Index (BMI) has been associated with adverse health outcomes in non-HIV and HIV populations, yet among HIV-infected individuals, a higher BMI at diagnosis offers a slower progression from HIV to AIDS. Pre-HAART, studies reported that obese HIV-infected individuals have higher increases in CD4 count over time. However post-HAART, some report that overweight HIV-infected individuals with …
