Making a case for the examination of ethnicity of Blacks in United States Health Research

Abstract

Important differences between Blacks of different ethnicities in the U.S. in chronic disease morbidity and mortality have been reported. Blacks in the U.S. constitute a heterogeneous group, including immigrants from Africa, Caribbean nations, Central and South America, as well as people now known as African Americans. Ethnicity among Blacks is seldom examined in health research, although in-depth examination of the ethnicity and culture-related pathways through which psychosocial factors may act to influence health have the potential to improve our understanding of health disparities. This improved understanding could in turn lead to the development of new, innovative, culturally based interventions that may reduce health disparities in the U.S. We briefly review the literature that examines Black ethnicity and birthplace, health outcomes, health-related knowledge and behaviors, and health-related psychological and social factors. We present a conceptual framework to aid in understanding the links between these factors and health. Suggestions are offered for conducting research in the future.
