Faculty Publications

We aimed to investigate associations of the dietary inflammatory index (DII) with glucose-insulin homeostasis markers, and the risk of glucose intolerance. This cross-sectional study included 2975 adults from the Tehran Lipid and Glucose Study. Fasting plasma glucose (FPG), 2-h post-load glucose (2h-PG), and fasting serum insulin were measured. Homeostatic model assessment of insulin resistance index (HOMA-IR) and β-cell function (HOMA-B), and the quantitative insulin sensitivity check index (QUICKI) were calculated. Glucose tolerance abnormalities included impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and type 2 diabetes (T2DM). DII scores were positively associated with 2h-PG (β = 0.04; p = 0.05). …

Sleep Disruption And Cancer Incidence In A Southeastern Veteran Population, Alexandria F. Delage

Theses and Dissertations

Sleep disruption influences biological processes that can facilitate carcinogenesis. However, studies examining the relationship between sleep disruption and cancer risk have been inconclusive. This retrospective cohort study used de-identified data from the Veterans Administration (VA) electronic medical record to test the hypothesis that sleep disorder diagnoses among Veterans seeking care in the Southeast United States Service Network are associated with increased risk for cancer of the prostate, breast, colorectum, or total cancer (1999-2010, N=663,869). Sleep disorders were defined as patients with an in- or out-patient diagnosis as specified by the International Classification of Sleep Disorders. Cancer cases were defined as …

Effectiveness Of Community-Based Eibi Treatment: A Longitudinal Analysis Of Adaptive Behavior And Language Outcomes, John Kuntz

Theses and Dissertations

Autism spectrum disorders (ASDs) are a group of lifelong, neurodevelopmental disorders characterized by deficits in social interaction, communication, relationship development and by the presence of repetitive or stereotypical behaviors including restricted interests. Continued advances in understanding treatment outcomes and broadening access to effective treatment is critical to improving the quality of life of children with autism and their families and minimizing the cost associated with care. The overall aim of this study is to assess the effectiveness of a community-based implementation of an Early Intensive Behavioral Intervention (EIBI) treatment program through a large-sample, longitudinal secondary analysis of administrative data. Additionally, …

Smoking-Related Stigma: A Public Health Tool Or A Damaging Force ?, Paula A. Lozano

Theses and Dissertations

Cigarette smoking is the leading cause of preventable death in the world. In an effort to address the tobacco epidemic, the World Health Organization’s Framework Convention on Tobacco Control (FCTC) has formulated a number of policies that are thought to reduce cigarette consumption by making smoking socially unacceptable. It is possible that tobacco control policies that aim to make smoking socially unacceptable may also result in the stigmatization of smokers. Social factors such as social norms and socioeconomic status may also influence the development of smoking-related stigma. While some researchers suggest that smoking-related stigma may be an important public health …

Low-Intensity Physical Activity And Cardiometabolic Risk Factors Among Older Adults With Multiple Chronic Conditions, Yueyao Li

Theses and Dissertations

Introduction:

Cardiovascular disease (CVD) is the leading cause of death among older adults in the Unites States and is driven largely by cardiometabolic risk factors including elevated blood pressure and blood glucose. Studies have found the protective effect of moderate intensity physical activity (MIPA) and vigorous intensity physical activity (VIPA) on cardiometabolic risk factor; however, the association between light physical activity (LIPA) and cardiometabolic risk factor among older adults is not clear.

Objectives:

1. Examine the association between LIPA and cardiometabolic risk factors.
2. Examine whether the association between LIPA and cardiometabolic risk factor is moderated by multiple chronic conditions. …

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 …

The Association Between Physical Activity And Serum Immunoglobulin G (Igg) Antibodies Against Periodontal Bacteria, A. Paige Anderson

Theses and Dissertations

The purpose of this study is to add more research and evidence to the mechanisms surrounding periodontal disease, periodontal microorganisms, and physical activity. The main objective of this study is to evaluate and explore the association between physical activity and serum IgG antibodies, which are grouped into four distinct clusters, formed from species specific 19 periodontal antibody titers. This cross sectional study divided physical activity into three categories: adequately physically active, inadequately physically active, and inactive based on MET scores. Certain models were adjusted for confounders including age, sex, race/ethnicity, income-to-poverty ratio, years of formal education, smoking, alcohol intake, BMI, …

The Influence Of Fine Particulate Matter On Inflammatory Bowel Disease In South Carolina: An Ecological Analysis, Joshua Eric Sellner

Theses and Dissertations

Background. The Inflammatory Bowel Diseases, including both Ulcerative Colitis and Crohn’s Disease, are lifelong disorders of the Gastrointestinal tract. In recent years, both conditions have become much more prevalent and recognized as major public health issues. Environmental factors have become the focus of recent research around the cause of these diseases. Although shown to have detrimental effects on diseases similar to that of the Inflammatory Bowel Diseases, fine particulate matter’s role in these diseases has not been adequately investigated.

Aim. The purpose of this study was to test the relation of fine particulate matter with hospitalizations attributable to …

Progesterone-Only Oral Contraceptive Pill, Breast Cancer, Heart Disease, And Stroke, Marsha Ema Samson

Theses and Dissertations

There is evidence from earlier studies that oral contraceptive pills may be a risk factor for certain chronic diseases, including heart disease, stroke, and breast cancer. Previous studies mainly focus on the estrogen component of combined (estrogen+ progestin) oral contraceptives (COCs) due to their popularity. This focus limits our understanding of progestin-only contraceptives and its relationship to commonly occurring chronic diseases. To provide insight into alternative methods of oral contraception, this dissertation explores the relationship between progestin-only oral contraceptive (POC) pills and heart disease, stroke, and breast cancer. We hypothesize that women using POCs are less likely to have certain …

Depression Among Pregnant Latinas In South Carolina, Andrew Fogner

Theses and Dissertations

The aim of the study was to determine the prevalence of depression among pregnant Latinas. To bring to light the importance of prenatal depression prevention, we assessed the effect of the quality of healthcare providers among South Carolina Latinas (n=171). Women answered a validated CES-D and were categorized as depressed (score >16). In multivariate analyses, good perception of quality of healthcare was more likely among women who were not depressed; adjusted odds ratio of 0.75, 95% confidence interval 0.37 – 1.55. The findings show the need for tailoring healthcare to Latinas with prenatal depression prevention. It is imperative to understand …

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), …

The Influence Of Prenatal And Early Life Factors On Bmi Z Scores And The Risk Of Being Obese In Early Childhood, Junxiu Liu

Theses and Dissertations

Childhood obesity is a serious public health challenge. The underlying causes behind the rising levels of childhood obesity might be driven by prenatal and early life factors. Recently, several studies have examined the association between gestational weight gain (GWG) and the risk of obesity in the pediatric population. Findings on the association of both inadequate and excessive GWG with offspring obesity are inconsistent and vary by maternal prepregnancy body mass index (BMI) status. Inconsistent findings also exist for the association of GWG and BMIZ as a continuous outcome. Nevertheless, existing studies mainly focus on the BMIZ upper centiles using logistic …

Sleep Disorder Trends, Epigenetic Markers, And Genetic Variation Of Circadian Genes In Adenomatous Polyp Formation, Melannie Alexander

Theses and Dissertations

Introduction: Sleep disturbances and sleep quality have fluctuated over time in the United States (US). Virtually every physiological process follows a circadian pattern, and cellular processes (i.e., cell proliferation, DNA damage response, and apoptosis) are often disrupted by sleep disturbances and other factors, potentially giving rise to adverse health outcomes such as cancer. Additionally, both genetic variation and epigenetic patterns within clock genes, which may affect sleep quality, also may increase one’s risk for developing cancer. The role of sleep disturbances in the formation of adenomas, precursor lesions to colorectal cancer (CRC), has been explored previously; however, little is …
