Theses and Dissertations--Epidemiology and Biostatistics

Using live and stillbirth records from Kentucky (2008-2017), this dissertation assessed the county-level prevalence and geospatial patterns of early-onset hypertensive disorders of pregnancy (eHDP); examined the geocoding precision of addresses recorded on birth records, and evaluated the association between individual risk factors and environmental metal exposures on eHDP prevalence. After adjusting for maternal demographic factors and pre-existing health conditions, we observed that eHDP prevalence was 38% higher (aPR=1.38, 95%CI:1.16, 1.64) in counties with the highest prevalence of married women (> 53.8%) compared to lower prevalence areas (31.6%) had a 20% higher prevalence of eHDP(aPR=1.20, 95%CI:1.00, 1.44) compared to counties with …

Landscapes Of Danger: A Geospatial Analysis Of Perceived And Realistic Risk In Bryce Canyon National Park, Tia Francis

Graduate Theses and Dissertations

The quantification of risk has inspired a wide breath of literature from the physical sciences, social sciences, and interdisciplinary disciplines like geography. Many attempts to estimate risk via natural hazards either focus on quantifying realistic risk or perceived risk of lay persons, with very little overlap between these paradigms. Due to this, a considerable knowledge gap exists within perceived risk and natural hazards research. This study aims to provide a comprehensive, risk estimation and assessment strategy through a multi-hazard risk assessment of Bryce Canyon National Park (BRCA). This case study analyzed knowledge of risk among visitors with perception surveys and …

Comparing Individual Perceptions Of Food Desert With Quantitative Measures In Omaha, Nebraska., Hector N. Samani, Bradley Bereitschaft

UNO Student Research and Creative Activity Fair

Food deserts have been linked to an increase in chronic diseases such as obesity and diabetes, due to lower access to affordable and healthy foods. The United States Department of Agriculture (USDA) outlines various methods and variables for defining food deserts, in attempts to standardize what constitutes a food desert or their characteristics. The USDA identifies the state of Nebraska as having both rural and urban food deserts, with an increase of food insecurity from 1.1% – 3.0% between 2007 and 2012 and warns of further increase of food deserts and its impact if measures are not taken. However, there …

Analyzing Trends And Patterns In Adverse Birth Outcomes In Massachusetts From 2000-2014, Madeleine Haynes

Sustainability and Social Justice

This study explores spatio-temporal trends and patterns in adverse birth outcomes (ABO) in the state of Massachusetts from 2000-2014. ABO include low birth weight (< 2500 g) and preterm deliveries (gestational age < 37 weeks). This research evaluates if there are areas in Massachusetts that have experienced statistically significant increases or decreases in ABO throughout the study period. Birth data was obtained from the Massachusetts Department of Public Health and only singleton, live births were included for the analysis. The data were aggregated to census tracts, and the total number of births and the number of ABOs were calculated for each census tract for each year. In total, 1478 census tracts were included in this analysis. Births to non-Hispanic black mothers and births to non-Hispanic white mothers were separated to evaluate if trends in ABO are similar regardless of race as previous literature has identified a much higher rate of ABO in births to non-Hispanic black women. Trends and patterns of ABO were evaluated using the Space Time Cube and the Mann-Kendall statistic and a multivariate regression was conducted to identify potential correlations between socioeconomic factors and prevalence of ABO. Results of this study can be used to identify areas that are experiencing an increase in ABO to potentially allow for more effective, targeted intervention methods.

Incorporating Place And Space: A Hierarchical Spatial Approach To Exploring Preventable Congestive Heart Failure Hospitalizations In New York City, Rachael Weiss Riley

Dissertations and Theses

Background: Faced with rising medical care costs, increasing prevalence, and widening health disparities, preventing congestive heart failure (CHF) hospitalizations is a central public health concern. Despite evidence of geographical clustering in preventable CHF admissions, there is a lack of research designed to examine spatial patterning of CHF and the local area neighborhood determinants that contribute to this variability. This study sought to assess and evaluate the importance of both space and place in analyzing preventable CHF hospitalizations and readmissions by applying appropriate statistical techniques, clarifying the assumption inherent in each method, and interpreting the findings within the context of existing …

Community Schools: A Public Health Opportunity, Catherine Diamond

Dissertations and Theses

Community schools link students, families, and communities to educate children and strengthen neighborhoods. They have become a popular model for education in many U.S. cities in part because they build on community assets and address multiple determinants of educational disadvantage. Since community schools seek to have an impact on populations, not just the students enrolled, they provide an opportunity to improve community health. It has been proposed that community schools influence the health and education of the area residents through three pathways: building trust, establishing norms, and linking people to networks and services. However, no research has been published exploring …
