Bridging social capital describes the diffusion of information across networks built between individuals of different social identities. This project aims to understand if the bridging ties of economic connectedness (EC), measured by data from Facebook friends and calculated as the average share of high socioeconomic status friends that an individual from a low socioeconomic status has, can be a predictor of variations in COVID-19 infection risk across Arizona ZIP code tabulation areas (ZCTAs). Economic connectedness values across Arizona ZCTAs was examined in addition to the correlation of EC to various social and demographic factors such as age, sex, race and ethnicity, educational background, income, and health insurance coverage. A multiple linear regression model was conducted to examine the association of EC to biweekly COVID-19 growth rate from October 2020 to November 2021, and to examine the longitudinal trends in the association between these two factors. The study found that the bridging ties of economic connectedness has a significant effect size comparable to that of other demographic features, and has implications in being used to identify vulnerabilities and health disparities in communities during the pandemic.

Our thesis revolved around the Maryvale community and was centered by a Photovoice project that was a Youth Participatory Action Research method. Being a project led by the youth we continued their stories and expanded off of the topics that we discussed in our Photovoice meetings. In our thesis podcast we discussed the expectation and reality of moving to a new country, the colorism our community as well as other communities face, and the health disparities that are present within underrepresented communities. We were able to expand on these topics and tie it back to the conversations we had with each other four years prior to doing our podcast and how little or how much these topics have changed and evolved.

This thesis addresses the global and national health landscape of disparities to provide insight into the social factors such as education, socioeconomic status, and environment that impact marginalized groups. A positive correlation between race, residency, and lower socioeconomic status among global and national landscapes was made with oral health disparities demonstrating poorer health outcomes among these groups. Through a multistep approach this thesis aimed to provide solutions to contribute to the efforts of developing effective policies and interventions that aim to promote oral health equity.

For most women, pregnancy is the period in which they will have more interaction with the healthcare field than any other period in their lives. The quality and accessibility of obstetric care varies greatly throughout the United States, and health disparities in this field have the largest impact on African American women. Black mothers in the U.S. are three to four times more likely than white mothers to die as a result of pregnancy related complications. The increased risk of maternal morbidity and mortality seen in the African American population is largely due to preventable causes. This thesis project includes three case studies which analyze the most prevalent and preventable sources of health disparity affecting Black mothers: preeclampsia, hemorrhage, and cesarean section. Possible solutions to each of these disparities are explored on an individual, institutional, and societal scale.
