Identifying Factors Associated With Syringe Reuse Among People Who Inject Drugs (Pwid) In Appalachia Kentucky, Grayson Keith Fuller

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

Aim: Syringe reuse contributes to the spread of infectious diseases. The purpose of this study is to identify factors associated with syringe reuse among people who inject drugs (PWID) in Kentucky.

Methods: PWID (n=238) completed interviewer-administered questionnaires to collect data on syringe reuse and demographic, behavioral, and clinical characteristics. Negative log binomial regression was used to model the associations.

Results: On average, people reused each syringe 9.3 times (median: 3; IQR: 2-10, range 1-95). Syringe reuse was higher among men [aOR=1.386; 95% CI: 1.041-1.845] and those who injected methamphetamine [aOR=2.122; 95% CI: 1.445-3.116]. Reuse was also higher among those who …

Triple Negative Breast Cancer In An Appalachian Region: Exponential Tumor Grade Increase With Age Of Diagnosis, Gina Sizemore, Toni Marie Rudisill

Journal of Appalachian Health

Introduction: Triple negative breast cancer is an aggressive breast cancer with decreased five-year survival, increased risk for recurrence, and higher risk for metastases. Unlike other breast cancers, it has no targeted treatment and has heterogeneous genetics which make classification and treatment difficult.

Purpose: The purpose of our research was to compare triple negative breast cancer to non-triple negative breast cancer to identify key epidemiologic factors that might lead to improved basic science directives for biomarkers, treatments, and classification.

Methods: The state cancer registry was used to provide the first West Virginia state-wide population evaluation of triple negative breast cancer.

Results: …

Exploring Covid-19 Case Fatality In Relation To The Prevalence Of Chronic Conditions And Health Behaviors In Appalachian Kentucky, W. Jay Christian

Journal of Appalachian Health

Background: Research has demonstrated that common chronic conditions, especially those related to cardiovascular health, are important risk factors for severe COVID-19 symptoms or hospitalization. Population prevalence rates of such conditions have not previously been examined in relation to COVID-19 case fatality rates in the Central Appalachian region.

Purpose: This study examined prevalence rates of selected chronic conditions and COVID-19 case fatality rates to determine whether the relationship between them is consistent across Appalachian and non-Appalachian regions of Kentucky.

Methods: Data from Kentucky’s Behavioral Risk Factor Survey (KyBRFS) were used to calculate prevalence rates of asthma, diabetes, influenza vaccination, hypertension, obesity, …

Environmental Respiratory Exposures And Pulmonary Function Among Residents Of Rural Appalachia, Kentucky, John C. Flunker

Theses and Dissertations--Epidemiology and Biostatistics

Introduction

Resource extraction exposures are hypothesized to promote adverse respiratory health outcomes among residents of rural Appalachia, yet no studies to date have simultaneously quantified small-scale geographic variation in residential exposure, individual level health factors, and respiratory health outcomes.

Methods

The Mountain Air Project (MAP) is a community engaged cross-sectional study based in Harlan and Letcher counties of Southeastern Kentucky. MAP utilized a novel small-scale method to define residential exposure boundaries: hydrologic unit code (HUC), which represents distinct drainages (AKA “hollows”) where residents cluster. We assigned the HUC level density of active and abandoned surface and underground mining, oil/gas wells, …

Maternal Proximity To Mountaintop Removal Mining And Birth Defects In Appalachian Kentucky, 1997-2003, Daniel B. Cooper

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

Background: Extraction of coal through mountaintop removal mining (MTR) alters many dimensions of the landscape, and explosive blasts, exposed rock, and coal washing have the potential to pollute air and water with substances known to increase risk of developmental and birth anomalies. Previous research suggests that infants born to mothers living in MTR coal mining counties have higher prevalence of most types of birth defects.

Objectives: This study seeks to examine further the relationship between MTR activity and birth defects by employing individual level exposure estimation through precise satellite data of MTR activity in the Appalachian region and maternal residence …
