Advancing the science of health disparities research.

Research to eliminate health disparities in the United States is best approached from the perspective of population health. The objectives of this paper are to: (a) describe how ongoing research at the eight national Centers for Population Health and Health Disparities (CPHHD) is using a population health perspective and a community-based approach to advance the field of health disparities research; and (b) to discuss potential implications of such research for health policies that target some of the determinants of population health.
