Dr. Stevens’ grants have generated over 26 million dollars to support her research, and she also has collaborated on projects with other investigators to secure millions of dollars in funding.  She coordinated a series of large, multi-center national trials that have tested behavioral interventions aimed at improving the health of children by promoting lifestyle changes.  Her role as Principal Investigator of coordinating centers is to monitor and enhance study methodology and to participate in the statistical analysis and presentation of scientific results. Dr. Stevens also leads research to examine and compare differences in the impact of obesity on morbidity and mortality in African Americans, Asians and Whites. Another line of research generated equations to predict percent body fat from demographic and anthropometric data (American Body Composition Calculator /ABCC). Dr. Stevens has served as an obesity expert for the National Institutes of Health, the Centers for Disease Control, the Institute of Medicine and the World Health Organization.
