While genetics certainly plays a part in the incidence and prevalence of some diseases, when dealing with the health of the African American community in the USA, it would be overly simplistic to simply explore genetic issues. (I’m not saying you are doing this but the end of your article suggests that our health as a community will be improved if we factor in genetic issues.) Studies by the Nation Institutes of Health as well as more recent studies, all point to the reality of racism (as opposed to the fiction of race) as one of the factors in the health disparities among people of African descent in the USA. We are not only disproportionately poor (which accounts for some of the disparities), but we are not treated as well when we do access care, and are not offered the most up-to-date treatments for the same diseases as our Euro-American counterparts. The health disparities we experience hold true across standards measure of class (e.g. income, education, etc.). If we do not deal with the stereotyping of African Americans, and the undervaluation of our lives, all the new advances in medicine will not necessarily be used to benefit our communities.
