Dr. Yumary Ruiz’s research focuses on youth health disparities and protective factors that enable youth to overcome adversity. She uses quantitative and qualitative methodologies to identify specific interactions between cognitive processes (e.g., attitudes, beliefs, and knowledge) and social factors (e.g., migration) that affect health. Her work also seeks to identify health-promoting mechanisms, such as social support (e.g., parents, adult mentors, providers) and individual characteristics (e.g., resilience and coping strategies) that can be targeted to mitigate the harmful effects of socioeconomic and health disadvantages. The overarching goal of her research program is to develop innovative and empirically based interventions (e.g., use of mentors, provider–parent collaborations, and community health workers) to reduce health disparities among youth.
Currently Dr. Ruiz’s research focuses in the following areas:
- Latinx Health and Wellbeing: Understanding how population mobility, vulnerability, coping and resilience affect the health and well-being of Latinx populations, with a particular emphasis on Latinx youth.
- Health Behaviors among Vulnerable Youth: Identifying the influence of multilevel factors on behavior and highlight the protective role of social factors (i.e., caregivers, providers, adult-mentors) on negative health outcomes.
- Intervention Research and Health Disparities: Applying community-engaged and community participatory research approaches to enhance competencies among practitioners, community organizations, indigenous leaders (e.g., community health workers), and youth to conduct health promotion research and activities and empower communities to reduce health disparities.
Her work has been funded by the National Institutes of Health, U.S. Department of Agriculture, the Spencer Foundation, the Indiana Clinical and Translational Sciences Institute and several other funders. She has published in prominent journals, including the American Journal of Public Health, Pediatrics, Contraception, Global Public Health, Journal of Adolescence Research, Social Development, American Journal of Sexuality Education, and Children and Youth Services Review. She began her career as a public health practitioner, where she developed expertise in developing, implementing, and evaluating community-based initiatives to address childhood health and safety hazards in low-income, resource-poor neighborhoods.
Dr. Ruiz teaches undergraduate and master’s level public health courses.
