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.

How are perceptions of morality and disgust regarding meat consumption related to each other? Which factor is more salient in determining one's willingness to eat the meat of a specific animal? How do these answers vary across religious groups? This study investigates the ways that concepts like morality and disgust are related to food preferences and hopes to shed light on the mechanisms that enforce culturally sanctioned food taboos. The study compares 4 groups of people in the U.S.: Christians (n = 39), Hindus (n = 29), Jews (n = 23), and non-religious people (n = 63). A total of 154 participants were given surveys in which they rated their feelings about eating various animals. Data from Christian and non-religious groups exhibited similar patterns such as a high likelihood of eating a given animal when starving, while results from Jews and Hindus were consistent with their religion's respective food taboos. Despite these differences, morality and disgust are strongly correlated with one another in almost all instances. Moreover, morality and disgust are almost equally important considerations when determining willingness to eat when starving.

Description
Curanderos are Hispanic traditional healers who attend to their clients through spiritual, natural, and physical techniques. Recent studies have shown that a subset of the Hispanic population refer to these healers for HIV and STD treatment and believe they are important in a collaborative targeted HIV intervention. Thus, curanderos were interviewed and the lay population of Phoenix was sampled in order to get a better idea of the utility of these healers in an HIV prevention effort targeted at the Hispanic community. Due to the limitations of this study there was not sufficient enough data to make significant conclusions; however the interviews with the curanderos were surprising in the they had significant roles as healers in the Phoenix area, patients have referred to them for HIV and STD treatment, and a couple of the healers have integrated western medical knowledge into their practice.

Description
Some scholars have suggested that individuals are inclined to believe that they have souls because they are also inclined to believe that they have a core, immutable self. The present study will explore this question in several parts. First, what is the extent to which individuals report having a core self? Next, how do beliefs about a core self relate to belief or non-belief in an eternal soul? The final question looks at location as an extension of the core self and soul relationship. Where is the self perceived to reside within a dualistic framework, the body or the soul? This study assessed the stated beliefs of 200 respondents using Amazon Mechanical Turk as a recruiting platform. Greater belief in a core self was moderately associated with greater belief in an eternal soul (r= 0.30, p<.01), and with belief in the self as a reflection of the soul (r=0.31, p<.01) and as a reflection of the brain (r=0.21, p<.01). This suggests that belief in a core self does hold association with belief in an eternal soul. However, its perceived location seems to show little preference as residing withing the soul versus the body.

Description
The main purpose of this investigation is to determine the intensity, economic costs, and potential solutions to HIV/AIDS stigma in the United States and Tanzania. In order to accomplish this goal, a literature review was conducted, and an economic model was created to determine how HIV/AIDS treatment deterrence manifests and affects these countries. The results of the economic model suggested that Tanzania suffers greater economic loss due to HIV treatment deterrence than the United States, however, both countries lose a significant portion of GDP due to HIV treatment deterrence. Stigma materializes differently in each country based on a variety of sociocultural factors. These include the demographic groups most affected, the perception of those living with HIV, and how sexually transmitted infections are perceived within communities. The solutions to HIV stigma must be tailored to the country, culture, and context that it arises for interventions to be effective. To further prevent HIV/AIDS stigma and its economic consequences, the etiology of stigma and how it presents in different communities must be understood.

Description
In Western medicine, the hard sciences have generally been understood as the sole guiding force in patient care and treatment. However, both history and the present day suggest another strong influence on Western medicine: folklore. The term folklore can easily be dismissed as a term representing beliefs and stories of the past, but its relevance transcends time and continues to impact people daily. It “involves values, traditions, ways of thinking and behaving. It’s about art. It’s about people and the way people learn. It helps us learn who we are and how to make meaning in the world around us” (Sims & Stephens, 2011, pp. 1-2). With its wide range of influence, folklore exists as the umbrella term encompassing several categories. Folk beliefs are one of these categories and can develop from “observation, memory, testimony or inference” (Hutton, 1942, p. 83). Given that each of these forms are subject to some sort of error, folk beliefs become “a jumble of the true and the erroneous” (p. 84). Similarly, contemporary legends are narratives that often combine the physical and supernatural world to explain nuances or uncertainty present in the relevant experiences of a people. Folk beliefs can result in the formation of contemporary legends and they can also stem from contemporary legends. These two categories are often associated with subjects that promote fear and uncertainty, and thus play an essential role in navigating folklore’s application to biomedicine. This paper explores the historical and modern effects that folklore has had on two separate maladies: Hansen’s Disease (leprosy) and Major Depressive Disorder (depression). While these conditions do not resemble each other in physical presentations, Hansen’s Disease and Major Depressive Disorder patients both have faced and continue to face discrimination. Andrea Wiley and John Allen’s three-part definition of a malady: society’s perception (sickness), the individual’s experience (illness), and medical professionals’ diagnosis and treatment (disease); was utilized as a tool for analyzing the application of folklore to modern medicine. The way that a society views a particular malady often dictates the sick role expected of a diagnosed individual. Additionally, the public’s view can directly affect medical professionals’ understanding of a malady. This then can drastically shape a patient’s diagnosis, treatment, and prognosis. This anthropological analysis acts as an interdisciplinary bridge between medicine and the humanities.

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.

Description
Significant health inequalities exist between different castes and ethnic communities in India, and identifying the roots of these inequalities is of interest to public health research and policy. Research on caste-based health inequalities in India has historically focused on general, government-defined categories, such as “Scheduled Castes,” “Scheduled Tribes,” and “Other Backward Classes.” This method obscures the diversity of experiences, indicators of well-being, and health outcomes between castes, tribes, and other communities in the “scheduled” category. This study analyzes data on 699,686 women from 4,260 castes, tribes and communities in the 2015-2016 Demographic and Health Survey of India to: (1) examine the diversity within and overlap between general, government-defined community categories in both wealth, infant mortality, and education, and (2) analyze how infant mortality is related to community category membership and socioeconomic status (measured using highest level of education and household wealth). While there are significant differences between general, government-defined community categories (e.g., scheduled caste, backward class) in both wealth and infant mortality, the vast majority of variation between communities occurs within these categories. Moreover, when other socioeconomic factors like wealth and education are taken into account, the difference between general, government-defined categories reduces or disappears. These findings suggest that focusing on measures of education and wealth at the household level, rather than general caste categories, may more accurately target those individuals and households most at risk for poor health outcomes. Further research is needed to explain the mechanisms by which discrimination affects health in these populations, and to identify sources of resilience, which may inform more effective policies.
