Associate Professor of Global and Environmental Health

Dr. Yesim Tozan’s research centers on health decision science and priority setting, and explores the costs and cost-effectiveness of health care interventions using decision analytic models and the issues of health care resource allocation in low- and middle-income countries. Her main focus has been infectious disease prevention and control with an emphasis on dengue and malaria. Dr. Tozan is currently leading a health economics work package in a European Union-funded research project on dengue surveillance and control with field sites in Sri Lanka and Thailand. She is also leading a prospective multi-center study on the cost of dengue illness in international travelers utilizing a network of travel clinics in Europe, the US, the Middle East and Australia. Most recently, she has been working on economic evaluation of artemisinin-based combination therapies for the treatment of uncomplicated childhood malaria using data from multi-site randomized clinical trials in Africa and Asia. Dr. Tozan was a task force associate for the UN Millennium Project’s Task Force on HIV/AIDS, Malaria, Tuberculosis and Access to Essential Medicines and was lead author of the malaria task force report entitled “Coming to grips with malaria in the new millennium.”

Abstract

Abstract

Understanding the heterogeneous experiences of violence experienced by Black and Latina women over the life course is critical to prevention. We identified four physical violence trajectories experienced by 361 Black and Latina women followed from ages 14 to 39: low/none (44.0%), persistent-moderate (36.8%), peak in the 20s (11.9%), and persistent-high (7.2%) violence exposure. Childhood abuse predicted membership in the three violence-exposed groups, whereas parental closeness, school academic orientation, and neighborhood safety were protective factors. Public health interventions aimed at preventing childhood trauma and ensuring safe interpersonal relationships and environments for girls to thrive are urgently needed.
