Gut Feelings: A Literature Review On The Gut-Brain Axis And Its Potential Influence On Mood, Grace Johnson

University Honors Theses

In recent decades, research on the gut-brain axis has evolved due to an increasing interest in the connection between gut health and mental health. The gut-brain axis presents a new frontier of health for both medical professionals and psychologists as there is expanding evidence illustrating the comorbidity of gut disorders and mood disorders. Due to the complex nature of studying the gut-brain axis and the myriad of influences on mood disorders such as depression, research has yet to find significant results definitively tying the two together. Nonetheless, the current body of literature on the topic provides a promising outlook on …

Let Kids Sleep: The Role Of Interdisciplinary Neuroscience Outreach In Stimulating Brains And Developing Research-Informed Approaches To Community Concerns, Marc Chenard

University Honors Theses

Northwest Noggin (NW Noggin), an all-volunteer neuroscience education outreach non-profit, serves its community by bringing students, artists, scientists and other participants together for artistic collaboration and learning. The outreach takes place in K-12 schools and other institutions (such as museums, coffee shops and correctional facilities) all over the Pacific Northwest. Neuroscience education outreach generates discourse surrounding community concerns through illuminating the brain-centric qualities of issues and by drawing on neuroscience research to create solutions. The neuroscience research-informed perspectives on these concerns stimulate awareness, create momentum towards evidence-based reform, and can result in policy interventions. This thesis details how NW Noggin …

Health Of Transgender Adults, 2020, Addie Furrer

University Honors Theses

Transgender and gender diverse individuals are known to experience barriers to accessing medical care while also being at higher risk of chronic conditions. In this study, the health conditions, disabilities, and health care access of 1,017 transgender and gender diverse(TGD) respondents to the 2020 Behavior Risk Factor Surveillance System were examined in relation to both cisgender men and cisgender women. This analysis was done to further the effort of understanding the health disparities experienced by TGD populations. Transgender and gender diverse individuals were more likely to have poor overall health and mental health, have multiple chronic health conditions, and have …

Engaging Public Health Critical Race Praxis In Local Social Determinants Of Health Research: The Youth Health Equity And Action Research Training Program In Portland, Or—Yheartpdx, Ryan J. Petteway, Lourdes Gonzalez

OHSU-PSU School of Public Health Faculty Publications and Presentations

The social determinants of health (SDH) have long been considered a core mechanism through which racial health inequities are (re)produced and incubated in the U.S. Moreover, scholars have expressly—and appropriately—named structural racism as a precursor to inequities associated with SDH. However, while research on racial health inequities—SDH-related or otherwise—continues to grow, communities of color remain grossly underrepresented as public health researchers and practitioners. Additionally, although SDH are experienced in a very local sense, much research and practice fails to more deeply and thoroughly engage and center local community knowledges. Thus, much work around SDH and racial health inequities presents, ironically, …

Exploring Connections Between Food Sovereignty, Cultural Food Access And Urban Health Promotion: A Systematic Review Of The Literature, Stephanie L. Kenyon

University Honors Theses

Marginalized urban communities face disproportionate rates of food insecurity related health outcomes and are more likely to lose important connections to traditional and cultural foods. Food sovereignty approaches, including policy changes, decolonized methods and community created perspectives to research and interventions have the potential to impact access to traditional and cultural foods, improving food security and supporting a healthier diet. The evidence in support of a food sovereignty approach to public health research and practice is limited and much of what is known is primarily based on studies at the global level or on rural communities. This systematic literature review …

The Digital Divide And Health: Examining Digital Access As A Social Determinant Of Health, Elizabeth Melissa Withers

Dissertations and Theses

This dissertation is comprised of three papers that consider ways in which one's level of digital access may impact self-rated health. Data are from multiple years of three separate nationally representative cross-sectional surveys: National Health Interview Survey, General Social Survey, and Health Information National Trends Survey to address the primary overarching research question: Is there an association between digital access and health? The examination of the relationship between digital access and health is situated within a social determinants of health perspective and draws on van Dijk's (2005) causal and sequential model of digital access. Education, income, race and ethnicity, work …

What You Should Know About Racism-20: A Fact Sheet In The Time Of Covid-19, Ryan J. Petteway

OHSU-PSU School of Public Health Faculty Publications and Presentations

Satire has a history within public health and medical scholarship. However, research and academic works related to COVID-19, health inequities, and structural racism to date have not engaged/explored satire as a critical mode of reflection, analysis, and commentary. Drawing from social epidemiology literature related to structural racism, and rooted in critical race theory and critical theory related to narrative power, this paper—in the form of a "RACISM-20" fact sheet/health promotion flyer—uses satire and humor as critical commentary on mainstream public health discourse of/responses to COVID-19, transposing structural racism and COVID-19 to accentuate how individualist, apolitical, and “colorblind” downstream frames of …

Organizational Risk In Multi-Sector Health Partnerships: A Case Study Of Oregon's Accountable Health Communities, Shauna Jean Nicole Petchel

Dissertations and Theses

The literature on collective action has documented that the perception of organizational risk -- both the uncertainty of potential outcomes and the meaning attached to them -- is an important factor in whether and how organizations engage in cross-sector collaborations. Yet there are few examples to date that document how health and social service leaders perceive organizational risks in cross-sector health partnerships focused on social determinants of health, or how their perceptions influence organizational commitment and willingness to engage in these partnerships over time.

This research aimed to fill this gap through a mixed methods case study of health and …

The Epidemiology Of Firearm-Related Injuries Presenting At The Two Level-1 Trauma Centers In Oregon From 2009-2019, Kamil Narayan, Kathleen F. Carlson, Susan Defrancesco

OHSU-PSU School of Public Health Annual Conference

Injury is an important clinical and public health problem worldwide. Firearm-related injury is an important source of trauma-related morbidity and increases the risk of death. The CDC reports that in 2017, 74.5% of homicides deaths and 50.6% of suicide deaths were caused by firearms. The purpose of our retrospective chart review is to describe the epidemiology of firearm-related injuries presenting in the emergency department of two level-1 trauma centers in Oregon over a 10-year period. The study involves victims of gunshot injuries of all ages who were treated in the OHSU and Legacy Emanuel Emergency Department during the calendar years …

How Urban Land Use Contributes To Inequitable Health Outcomes: An Interdisciplinary Review & Analysis, Bliss Storm Croton

University Honors Theses

Using existing literature as a basis for initial review, this paper seeks to explore the relationship between urban land use and socioeconomic status as both pertain to the prevalence of psychological health diagnoses among neighborhood residents. The purpose of this analysis is to investigate the combined literature from multiple areas of research in order to gain a more holistic, up-to-date scope of knowledge regarding how discriminatory neighborhood land use may result in poorer psychological health outcomes for urban populations. By utilizing an interdisciplinary approach, some of the locally relevant, long-term impacts of uneven development and environmental injustice are examined based …

Impactful Care: Addressing Social Determinants Of Health Across Health Systems, Nicole Lisa Friedman

Dissertations and Theses

There is emerging evidence that addressing health-related social needs through enhanced clinical-community linkages can improve health outcomes and reduce costs. Unmet health-related social needs, such as food insecurity, inadequate or unstable housing, and lack of access to transportation may increase the risk of developing chronic conditions, reduce an individual's ability to manage these conditions, increase health care costs, and lead to avoidable health care utilization. In response, work on social needs is happening across large health systems in the United States, but the pace of progress is slow and accountability is diffuse.

The goal of this applied research project is …

Social Norms, Misperceptions, And Mosquito Net Use: A Population‑Based, Cross‑Sectional Study In Rural Uganda, Jessica M. Perkins, Paul J. Krezanoski, Sae Takada, Bernard Kakuhikire, Vincent Batwala, Alexander Tsai, Nicholas A. Christakis, David R. Bangsberg

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Mosquito net use is an essential part of malaria prevention. Although previous research has shown that many people sleep under a mosquito net in endemic areas, it is unknown whether people underestimate how common it is to sleep under a net every night. Furthermore, perceived social norms about whether most others sleep under a mosquito net every night may contribute to personally sleeping under a net, given decades of research showing that people often mimic others’ behaviours.

Methods: Population-based data were collected from 1669 adults across eight villages in one rural parish in southwestern Uganda. Individuals’ perception about whether …

Geospatial-Temporal, Demographic, And Programmatic Adoption Characteristics Of A Large-Scale Water Filter And Improved Cookstove Intervention In Western Province, Rwanda, Katie Fankhauser, Corey L. Nagel, Christina Barstow, Miles Kirby, Evan A. Thomas

OHSU-PSU School of Public Health Faculty Publications and Presentations

Lowering the global disease burden of preventable disease has been addressed in part by the distribution of health products and behavior change campaigns in low-income countries. Realizing a health impact requires adoption by participants, and the topic of program uptake and sustained adoption has been studied extensively, although an ecological context is largely missing from existing work. This study characterizes self-reported and observed adoption of improved cookstoves and point-of-use water filters among nearly 80,000 households in Rwanda using demographic and programmatic variables from implementer surveys and integration of geospatial and temporal data based on differentiated recipient location. The odds of …

Objective Monitoring Of Insecticide-Treated Bednet Use To Improve Malaria Prevention: Smartnet Development And Validation, Paul J. Krezanoski, Data Santorino, Jeffrey Campbell, David Bangsberg

OHSU-PSU School of Public Health Faculty Publications and Presentations

Malaria is a serious health concern for three billion people worldwide, killing nearly 600,000 people a year. Insecticide-treated bednets (ITNs) are an effective and valuable tool for preventing malaria and hundreds of millions of ITNs have been distributed throughout sub-Saharan Africa. Nevertheless, our current methods for measuring ITN use are inadequate to inform malaria prevention programs. The most common method, self-reported ITN use, is limited by 1) social desirability, 2) recall and 3) sampling bias. An acceptable objective and longitudinal method of assessing adherence to ITN use would improve our ability to better understand the determinants of ITN use and …

Exposure To Elemental Carbon, Organic Carbon, Nitrate, And Sulfate Fractions Of Fine Particulate Matter And Risk Of Preterm Birth In New Jersey, Ohio, And Pennsylvania (2000–2005), Kristen M. Rappazzo, Julie L. Daniels, Lynne C. Messer, Charles Poole, Danelle T. Lobdell

Community Health Faculty Publications and Presentations

Background: Particulate matter ≤ 2.5 μm in aerodynamic diameter (PM2.5) has been consistently associated with preterm birth (PTB) to varying degrees, but roles of PM2.5 species have been less studied.

Objective: We estimated risk differences (RD) of PTB (reported per 106 pregnancies) associated with change in ambient concentrations of elemental carbon (EC), organic carbon (OC), nitrates (NO3), and sulfates (SO4).

Methods: From live birth certificates from three states, we constructed a cohort of singleton pregnancies at or beyond 20 weeks of gestation from 2000 through 2005 (n = 1,771,225; 8% PTB). We estimated mean species exposures for each week of …

A Novel Tool For Assessing And Summarizing The Built Environment, Gretchen L. Kroeger, Lynne C. Messer, Sharon E. Edwards, Marie Lynn Miranda

Community Health Faculty Publications and Presentations

Background: A growing corpus of research focuses on assessing the quality of the local built environment and also examining the relationship between the built environment and health outcomes and indicators in communities. However, there is a lack of research presenting a highly resolved, systematic, and comprehensive spatial approach to assessing the built environment over a large geographic extent. In this paper, we contribute to the built environment literature by describing a tool used to assess the residential built environment at the tax parcel-level, as well as a methodology for summarizing the data into meaningful indices for linkages with health data. …

Does Urban Noise Represent A Hazard To Health?, Frances J. Storlie

Dissertations and Theses

The problem of noise as a potential health hazard to urban man has been raised. The literature was used to establish two premises: that cities are noisy environments, and that noise-free societies have less coronary artery disease (CAD) than do industrialized sections of the world. These differences also hold for rural and urban areas of the United States.

Geographical questions concerning rate differentials for CAD have been addressed by numerous disciplines. Subsequently, social, psychological, and physical explanations have been put forth. Throughout this paper the emphasis has been placed on the physical aspects of noise exposure. The conceptual frame utilizes …
