This dissertation explored the career aspirations of Black and Latinx undergraduates in underrepresented health fields, crucial due to health disparities and social determinants. Using data from the 2015-2019 Higher Education Research Institute, the research analyzed factors impacting students' pursuit of healthcare careers through logistic regressions in three articles. The first article identified predictors of career aspirations among Black and Latinx students, showing significant racial and ethnic disparities. Asian American students have expressed the highest desire for healthcare careers (31.5%), followed by Black (28%), Latinx (19%), and White students (17.5%). The second study underscored the underrepresentation of Black and Latinx individuals, particularly women, in healthcare professions. The third article examined socioeconomic status, unveiling academic disengagement among those with low socioeconomic status within these groups. Both the first and second studies highlighted how negative internship experiences significantly forecast lower career aspirations, stressing the importance of evaluating internships among Black and Latinx students. Lack of internships emerged as a significant predictor in these studies. Conversely, self-identifying as "premed" positively predicted pursuing a healthcare career in the first and third studies. Across all studies, faculty bias and negative cross-racial interactions hindered aspirations, constraining opportunities for success. These findings underscored the overlapping challenges, systemic inequalities, and discrimination shaping the career aspirations of Black and Latinx students pursuing healthcare fields.
