OBJECTIVE: To investigate whether the excess incidence of diabetic end-stage renal disease (ESRD) among African Americans could be explained by racial differences in putative ESRD risk factors. DESIGN: Population-based, ecologic study using the 1981 and 1982 Maryland Statewide Household Hypertension Survey for data on risk factor prevalence. PARTICIPANTS: A total of 2.1 million adults residing within the boundaries of the Maryland Regional ESRD Registry, grouped by race and ZIP code into 26 subpopulations. MAIN OUTCOME MEASURE: Incidence rates of treatment for diabetic ESRD between 1980 and 1985 from the Maryland Regional ESRD Registry by subpopulation. RESULTS: Between 1980 and 1985, 442 persons entered treatment for diabetic ESRD. At the level of the subpopulation, diabetic ESRD incidence was positively associated with black race (relative risk [RR], 3.42; 95% confidence interval [CI], 2.84 to 4.13), prevalence of diabetes (RR, 2.35; 95% CI, 1.92 to 2.87), prevalence of poorly controlled hypertension (RR, 1.80; 95% CI, 1.45 to 1.86), lack of a regular source of health care (RR, 1.82; 95% CI, 1.62 to 2.05), and lower socioeconomic status as indicated by lack of college education (RR, 1.41; 95% CI, 1.32 to 1.52) (all, P < .0001). After adjusting for these risk factors, black race remained strongly associated with the overall incidence of diabetic ESRD (RR, 2.70; 95% CI, 1.89 to 3.86; P < .0001). Further analyses suggested that this excess risk among blacks was confined to ESR...
