Neighborhood And Environmental Predictors Of At-Risk And Problem Gambling In Massachusetts, Kendra E. Pugh Dec 2022

Neighborhood And Environmental Predictors Of At-Risk And Problem Gambling In Massachusetts, Kendra E. Pugh

Graduate Doctoral Dissertations

Despite the widespread impact and negative effects of problem gambling (PG), limited attention has been paid to the environment where PG occurs. This study investigated the relationship between gambling on lottery and the zip code where gambling occurs, as well as the influence of individual-level characteristics that predict at-risk or problem gambling (AR/PG), among Massachusetts residents. A GIS analysis was conducted to identify vulnerable areas based on neighborhood characteristics, lottery sales, and AR/PG. Overall, residents of disadvantaged areas did not spend more money on lottery or have more lottery agents than residents of less disadvantaged areas. Some indicators of disadvantage …

Exploring The Relationship Between Historical Redlining And Place-Based Reproductive Health Inequities: A Qualitative Gis Approach, Kristi L. Roybal Jan 2022

Exploring The Relationship Between Historical Redlining And Place-Based Reproductive Health Inequities: A Qualitative Gis Approach, Kristi L. Roybal

Electronic Theses and Dissertations

Individual-level risk factors and characteristics do not fully explain racial, ethnic, and socioeconomic inequities in preterm birth in the United States, and evidence suggests that medical advancements, increased access to prenatal care, and high per-capita spending on health care have done little to reduce these inequities. Health inequities research has shifted its attention from individual-level factors that influence health outcomes to the social determinants of health. Neighborhoods, considered an important upstream social determinant of health, can influence health outcomes through their social, service, and physical environments, and have been consistently linked to birth outcomes. Despite increased attention to neighborhood influences …

Synthesis Of A Multimodal Ecological Model For Scalable, High-Resolution Arboviral Risk Prediction In Florida, Sean P. Beeman

USF Tampa Graduate Theses and Dissertations

West Nile virus (WNV) and Eastern Equine Encephalitis virus (EEEV) represent the two greatest endemic arboviral risks to the state of Florida. Currently, no approved human vaccine exists for the prevention of either virus. In the absence of a vaccine, effective disease surveillance is paramount for public health. In Florida, WNV and EEEV sentinel chicken surveillance is conducted by mosquito control programs operated at the county, municipality, or special taxing district level. This program was implemented in 1978 following human outbreaks of St. Louis Encephalitis virus (SLEV) that occurred between 1959 and 1977, with initial sentinel coops placed in proximity …

On The Importance Of Context: Examining The Applicability Of Infertility Insurance Mandates In The United States Using A Mixed-Methods Study Design, Nathanael B. Stanley

USF Tampa Graduate Theses and Dissertations

Accessibility of infertility services is disproportionately experienced in the United States. Although there exist state-based health insurance mandates for infertility services, these mandates contain language that disqualify people from using them. In order to better understand why these mandates are not able to reduce the financial burden and bridge the income disparity for using infertility services, the purpose of this study is to add context to the applicability of these insurance mandates through qualitative and quantitative inquiry. Using the Glass and McAtee model of risk regulators as an operational paradigm, this research explores the role of environmental context, or “place”, …

Analyzing Trends And Patterns In Adverse Birth Outcomes In Massachusetts From 2000-2014, Madeleine Haynes May 2019

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

International Development, Community and Environment (IDCE)

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.

This study examined the association of distance from villages to ETUs …


Brownsfields To Greenfields: Environmental Justice Versus Environmental Gentrification, Juliana A. Maantay, Andrew Maroko Oct 2018

Brownsfields To Greenfields: Environmental Justice Versus Environmental Gentrification, Juliana A. Maantay, Andrew Maroko

Publications and Research

Gentrification is a growing concern in many urban areas, due to the potential for displacement of lower-income and other vulnerable populations. This process can be accelerated when neighborhood “greening” projects are undertaken via governmental or private investor efforts, resulting in a phenomenon termed environmental or “green” gentrification. Vacant land in lower-income areas is often improved by the existing community through the creation of community gardens, but this contributes to these greening efforts and paradoxically may spur gentrification and subsequent displacement of the gardens’ stewards and neighbors. “Is proximity to community gardens in less affluent neighborhoods associated with an increased likelihood …

Race And “Hotspots” Of Preventable Hospitalizations, Caryn N. Bell, Janice V. Bowie, Roland J. Thorpe Jr.

Journal of Health Disparities Research and Practice

Abstract

Preventable hospitalizations (PHs) are those for ambulatory care-sensitive conditions that indicate insufficiencies in local primary healthcare. PH rates tend to be higher among African Americans, in urban centers, rural areas and areas with more African American residents. The objective of this study is to determine geographic clusters of high PH rates (“spatial clusters”) by race. Data from Maryland hospitals were utilized to determine the rates of PHs in zip code tabulation areas (ZCTAs) by race in 2010. Geographic clusters of ZCTAs with higher than expected PH rates were identified using Scan Statistic and Anselin’s Local Moran’s I. 10 PH …
