However, the situation of anemia control for a large contingent of the hemodialysis population remains unknown. Studies in the United States indicate that hemoglobin level is lower for African Americans on MHD, but studies in other populations of African descent are lacking. We investigated the prevalence of, and associated factors for, hemoglobin \u226411 g\/dl in MHD patients from the Brazilian city with the largest proportion of African descendants outside Africa.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Cross-sectional study of 1,263 MHD patients enrolled in the Prospective Study of the Prognosis of Chronic Hemodialysis Patients (PROHEMO) in Salvador, Brazil 2005-2009.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>88.0% black or mixed race; age 49.0 \u2213 14.7 years; 96.6% receiving erythropoietin, median = 6,000 units\/week.
