The National Institutes of Health announces the transition of the National Center on Minority Health and Health Disparities (NCMHD) to the National Institute on Minority Health and Health Disparities (NIMHD). The transition gives the institute a more defined role in the NIHs research agenda against health disparities, which it defines as differences in the incidence, prevalence, mortality, and burden of diseases and other adverse health conditions that exist among specific population groups.
