Y. Claire Wang, MD, ScD


My research surrounds the theme of using modeling to integrate the evidence base to inform policy and practice guidelines. Specifically, I am interested in the distribution of modifiable risk factors (e.g. diet, exercise, and disease screening) and their joint implications on disease burden in the whole population and between demographic subgroups.

My present research focuses on the obesity epidemic in adults and in children. Supported by the Robert Wood Johnson Foundation, I have assessed behavioral and environmental determinants of energy balance (energy intake vs. energy expenditure) and an online tool to evaluate how various population-wide strategies and policies may help fighting obesity in children and adolescents. One key behavioral aspect I have worked on is the trend and caloric implications of the rapidly-rising intake of sugar-sweetened beverage among U.S. adults and youth.

I am involved with several projects to evaluate the health and economic impacts of levying excise taxes on sugar-sweetened beverages, including a report to the New York State in 2010. More recently, I have led research projects related to the assessment of clinical guidelines of cardiovascular disease prevention, such as guidelines for blood pressure and cholesterol screening as part of pediatric services, and using imaging technologies to screen for atherosclerosis in asymptomatic adults.
