BACKGROUND: Diabetes mellitus is a risk factor for target-organ damage/clinical cardiovascular disease in older persons. DESIGN: A retrospective analysis was performed of charts from all older persons (506 men and 1497 women, mean age 80 +/- 8 years) seen during the period from 1 January 1998 to October 1998 at an academic hospital-based geriatrics practice, to investigate the prevalence of diabetes mellitus, and the prevalence, in patients with diabetes, of target-organ damage/clinical cardiovascular disease, hypertension, hypertension or dyslipidaemia, obesity, the drugs used to treat diabetes, and poor glycaemic control. RESULTS: Diabetes mellitus occurred in 127 of 1150 whites (11%), in 93 of 444 African-Americans (21%), in 111 of 381 Hispanics (29%), and in four of 28 Asians (14%) (P 7%) occurred in 28 of 86 African-Americans (33%), in 69 of 104 Hispanics (66%), and in 23 of 118 whites (19%) (P < 0.001 comparing Hispanics with whites and comparing Hispanics with African-Americans; P < 0.05 comparing African-Americans with whites). CONCLUSIONS: The prevalence of diabetes mellitus in 2003 older persons seen in an academic hospital-based geriatrics practice was 17% and was greater in Hispanics than in whites or African-Americans, and greater in African-Americans than in whites. The prevalence of target-organ damage/clinical cardiovascular disease was 85% in 335 older patients with diabetes. The prevalence of stroke or transient cerebral ischaemic attack was greater in older African-Americans with diabetes mellitus than in older whites with the disorder. The prevalence of diabetic nephropathy and of target-organ damage/clinical cardiovascular disease was greater in older African-Americans with diabetes mellitus than in older whites and Hispanics with diabetes mellitus. The prevalence of poor glycaemic control was greater in Hispanics than in whites or African-Americans and greater in African-Americans than in whites.
