Description
Food system and health characteristics were evaluated across the last Waorani hunter-gatherer group in Amazonian Ecuador and a remote neighboring Kichwa indigenous subsistence agriculture community. Hunter-gatherer food systems like the Waorani foragers may not only be nutritionally, but also pharmaceutically beneficial because of high dietary intake of varied plant phytochemical compounds. A modern diet that reduces these dietary plant defense phytochemicals below levels typical in human evolutionary history may leave humans vulnerable to diseases that were controlled through a foraging diet. Few studies consider the health impact of the recent drastic reduction of plant phytochemical content in the modern global food system, which has eliminated essential components of food because they are not considered "nutrients". The antimicrobial and anti-inflammatory nature of the food system may not only regulate infectious pathogens and inflammatory disease, but also support beneficial microbes in human hosts, reducing vulnerability to chronic diseases. Waorani foragers seem immune to certain infections with very low rates of chronic disease. Does returning to certain characteristics of a foraging food system begin to restore the human body microbe balance and inflammatory response to evolutionary norms, and if so, what implication does this have for the treatment of disease? Several years of data on dietary and health differences across the foragers and the farmers was gathered. There were major differences in health outcomes across the board. In the Waorani forager group there were no signs of infection in serious wounds such as 3rd degree burns and spear wounds. The foragers had one-degree lower body temperature than the farmers. The Waorani had an absence of signs of chronic diseases including vision and blood pressure that did not change markedly with age while Kichwa farmers suffered from both chronic diseases and physiological indicators of aging. In the Waorani forager population, there was an absence of many common regional infectious diseases, from helminthes to staphylococcus. Study design helped control for confounders (exercise, environment, genetic factors, non-phytochemical dietary intake). This study provides evidence of the major role total phytochemical dietary intake plays in human health, often not considered by policymakers and nutritional and agricultural scientists.

Description
Despite the arid climate of Maricopa County, Arizona, vector-borne diseases have presented significant health challenges to the residents and public health professionals of Maricopa County in the past, and will continue to do so in the foreseeable future. Currently, West Nile virus is the only mosquitoes-transmitted disease actively, and natively, transmitted throughout the state of Arizona. In an effort to gain a more complete understanding of the transmission dynamics of West Nile virus this thesis examines human, vector, and environment interactions as they exist within Maricopa County. Through ethnographic and geographic information systems research methods this thesis identifies 1) the individual factors that influence residents' knowledge and behaviors regarding mosquitoes, 2) the individual and regional factors that influence residents' knowledge of mosquito ecology and the spatial distribution of local mosquito populations, and 3) the environmental, demographic, and socioeconomic factors that influence mosquito abundance within Maricopa County. By identifying the factors that influence human-vector and vector-environment interactions, the results of this thesis may influence current and future educational and mosquito control efforts throughout Maricopa County.

Description
The study examines cross-cultural perceptions of wastewater reuse from 282 participants from four global sites representing varied levels of socio-economic and political development from the Global North and Global South: Spain, New Zealand, Fiji, and Guatemala. The data comes from the Global Ethnohydrology Survey conducted by the School of Human Evolution and Social Change during the summer of 2013. The Global Ethnohydrology Study is a transdisciplinary multi-year research initiative that examines the range of variation in local ecological knowledge of water issues, also known as "ethnohydrology." Participants were asked about their willingness, level of disgust, and concern with using treated wastewater for various daily activities. Additionally, they were asked to draw schematic representations of how wastewater should be treated to become drinkable again. Using visual content analysis, the drawings were coded for a variety of treatment levels and specific treatment processes. Conclusions about the perceived health implications from wastewater reuse that can stem from drinking treated wastewater were made. The relationship between humans and wastewater is one that has many direct social and health impacts on communities at large. In reaction to global limitations of freshwater, wastewater serves as a valuable resource to tap into. This research examines the cross-cultural public health concerns about treated wastewater in order to draw conclusions that can aid in strategic implementation of advocacy and public education about wastewater reuse.

Description
Vaccine opposition is a growing problem in developed countries where dropping vaccination rates threaten general public health by laying the foundation for resurgence and reemergence of previously eradicated infectious diseases. This thesis argues that the current movement is only the most recent incarnation of opposition that has co-evolved with vaccine practices for the duration of their mutual histories. Part one provides a historical context for the current movement using the example of the development and deployment of the smallpox vaccine as a representative timeline of vaccine acceptance and opposition. Part two describes the current movement in the United States and the United Kingdom, interprets the reasons for the conclusions drawn by vaccine-concerned parents, and provides a framework for public health officials to approach the issues.

Description
Understanding more about the similarities and differences in cultural perceptions of climate change-related disease causation can better inform culturally specific public health measures. Using interviews conducted with 685 adults in eight diverse global locations ranging from Fiji and China to England and Phoenix, Arizona, this study explores climate change-disease beliefs within and across diverse cultures and comparisons between cultural and scientific models. A cultural consensus analysis was employed to identify a "culturally correct" model for each study site. Next, a scientific model was generated based on current scientific consensus regarding climate change- disease connections. Using the Quadratic Assignment Procedure (QAP), we determined the amount of correlation shared between the scientific model and each cultural model. The analysis revealed a high level of intercorrelation between the models of English speaking, economically developed sites such as Phoenix, Arizona. Additionally, cultural models from the non-English speaking sites were highly intercorrelated with one another. Overall, the English speaking sites tended to have more complex models with a greater density of causal links. Cultural models from the English speaking sites also demonstrated high levels of correlation with the scientific model. In comparison, the cultural models from the non-English speaking sites exhibited little correlation with the scientific model. Based on these findings, we suggest that cultural beliefs related to climate change-related disease causation may be influenced by complex local factors. For example, differences in education and media influences along with localized differences in climate change impacts may, in part, contribute to divergences between the cultural models.

Description
This study investigated the potential efficacy of HEAL International's prevention education program in inducing health behavior change in HIV/AIDS, malaria, and communicable disease to children in grade levels ranging from primary school to secondary school. The health education program was aimed at changing health behavior by increasing knowledge. This increase in knowledge was analyzed as a modifying factor in the Health Belief Model suggesting that knowledge, along with five other modifying factors, are directly responsible for an individual's health perceptions. These health perceptions ultimately result in an individual's health behavior. As a result, it is argued that an increase in knowledge can lead to health behavior change so long as it is coupled with a strong theoretical framework. Administering pre-evaluations at the beginning of the program, post evaluations at the end of the program, and a second post evaluation again two months later completed the evaluation. It was hypothesized that if there was a significant difference between the percent of correct answers at the pre-evaluation compared the second post-evaluation then there is evidence that HEAL's health education program is, or at least has the potential to, create sustainable health behavior change. A paired samples t-test was completed on the data and showed a statistically significant difference between the percent of correct answers at pre-evaluation and the percent of correct answers at second post-evaluation. These results indicated that the number of students with a comprehensive knowledge of the subjects that HEAL taught during the program had increased. It was concluded that the results of the study indicate evidence that HEAL's program has the potential to deliver sustainable health behavior change but that it will be more quantifiable once HEAL is able to adopt a theoretical framework on which to base future programs.

Description
Human Immunodeficiency Virus, or HIV, is a global epidemic, costing over 9.51 million individuals their lives since 2000. There are different modes of transmission of HIV, one such mode being from an HIV positive woman to her child before, during, or after delivery (SIC Curriculum, 2006). Though a global epidemic, not all countries have the same prevalence of mother to child, or MTC, transmission of HIV. In 2016, over 160,000 children under the age of five were newly infected with HIV in sub-Saharan Africa. That is compared to the United States of America, where it is estimated that fewer than 150 new infant HIV infections occur yearly (Glaser Foundation, 2020). Those differences exist despite both countries having access to preventative medication as of 1998.
Additionally, the World Health Organization, or WHO, developed three treatment plans for prevention of MTC transmission of HIV, globally available as of 2010 (WHO, 2010). The goal of the WHO was to globally standardize care of HIV-positive pregnant women and their infants in order to decrease the global prevalence of HIV. The first plan was called Option A, then came Option B, and lastly Option B+. While preventative medication has been available for over twenty years and at least one of these theoretically effective treatment plans has been implemented and is readily available in each country of sub-Saharan Africa, the overall prevalence of MTC transmission of HIV in sub-Saharan Africa has continued to be notably high compared to other countries. Thus, the aim of this thesis is to explore some of the significant obstacles to implementation of the WHO’s treatment plans in sub-Saharan Africa that contribute to that high prevalence. I also suggest possible solutions to those barriers in order to effectively decrease the prevalence of MTC transmission of HIV.

Description
Background: Endometriosis is a condition characterized by the growth of the endometrium, or the tissue that lines the uterus, outside of the uterus, and it is diagnosed through the presence of endometriotic lesions in the pelvic region. The disease is most often associated with abnormal and painful vaginal bleeding. Currently, minimal literature exists concerning the management of endometriosis in low and middle-income countries (LMICs), which may influence the lack of a cultural competent understanding of menstruation in LMICs and, therefore, a lack of evidence-based policies concerning menstruation.
Methods: Social and cultural barriers influencing endometriosis reporting and management in LMICs were examined through a systematic literature review. Online databases yielded a list of relevant studies. Then, use of MAXQDA, a qualitative data analysis software program, helped to extract and code specific text segments from each study that pertain to the research topic. In-context analysis of coded segments revealed the most common trends, which were organized into broader themes.
Results: Findings demonstrated that social and cultural ideas regarding vaginal bleeding influenced the lack of disease reporting and management of endometriosis in LMICs. Socioeconomic challenges include a lack of hygiene and sanitation measures and education regarding menstruation and vaginal bleeding. Also, many diseases associated with the abnormal vaginal bleeding are often disregarded and not prioritized in clinical settings. It also became clear that cultural taboos regarding menstruation and vaginal bleeding often create feelings of anxiety and fear in women and girls throughout communities in LMICs. However, further research is needed to examine the ways in which women in those communities treat symptoms of irregular vaginal bleeding related to endometriosis.
Conclusions: Socioeconomic, gender, and sex-related factors may influence the ways in which endometriosis is reported and treated and may affect the way the related diseases are understood. Evidence-based policies using a culturally competent understanding of abnormal vaginal bleeding in LMICs may help positively affect the reproductive health of women and girls in such areas.

Description
Contact tracing was deployed widely during the COVID-19 pandemic to attempt to stop the spread of SARS Co-V-2. This dissertation investigates the research on contact tracing from a scientometric perspective and looks qualitatively at how case investigators and contact tracers conducted public health practice during the pandemic. Through approaching the public health practice of contact tracing from both a broad, top-down angle, and an on the ground experiential approach, this dissertation provides insight into the issues facing contact tracing as a public health tool.

Description
Latest estimates show that roughly 188 individuals in the United States die everyday due to an opioid-related overdose. This dissertation explores three avenues for
mitigating opioid use disorder (OUD) and the opioid epidemic in the United States (1.)
How can researchers and public health professionals identify areas most in need of
treatment for OUD in an easy-to-use and publicly accessible interface?; (2.) What do
practitioners see as opportunities for reducing barriers to treatment?; and (3.) Why do
differences in opioid mortality exist between demographic groups? To address question
one, I developed an interactive web-based to assist in identifying those counties with the
greatest unmet need of medically assisted treatment (MAT). To answer question two, I
conducted a study of stakeholders (medical providers, peer support specialists, public
health practitioners, etc.) in four New Mexico counties with high unmet need of MAT. to
identify cultural and structural barriers to MAT provision in underserved areas as well as
opportunities for improving access. To answer the third question. I conducted a
systematic review of peer-reviewed literature and government reports to identify how
previous research accounts for race/ethnic and sex disparities in opioid-related
mortality. While many opioid mortality studies show demographic differences, little is
known about why they exist. According to the findings of this systematic review, research
needs to go beyond identifying demographic differences in opioid-related mortality to
understand the reasons for those differences to reduce these inequities.
