Key result
Elderly Black adults have ~39% higher hypertension prevalence than White peers, plus more diabetes and obesity.
Why the study?
What are the differences in the prevalence of coronary risk factors between elderly black and white individuals?
Cohort (n=1,414)
What are the differences in the prevalence of coronary risk factors between elderly black and white individuals?
Absolute Event Rate: 50% vs 36%
p-value: p=<0.001
Elderly black individuals have a higher prevalence of hypertension, diabetes, and obesity, and a higher rate of echocardiographic left ventricular hypertrophy among hypertensives, compared to elderly white individuals.
May inform targeted cardiometabolic screening in elderly blacks; leaves open whether interventions improve outcomes.
Coronary risk factors were determined in a prospective study of 1,414 elderly persons (999 women and 415 men), mean age 82 +/- 8 years. Of 1,414 persons, 215 (15%) were black and 1,140 (81%) were white. The prevalences of cigarette smoking, hypercholesterolemia, low serum high-density lipoprotein cholesterol, and increased serum total cholesterol/high-density lipoprotein cholesterol ratio were not significantly different in elderly blacks and whites. Elderly blacks had a higher prevalence of hypertension (50% versus 36%, P less than 0.001), diabetes mellitus (27% versus 19%, P less than 0.01), and obesity (11% versus 5%, P less than 0.005) and a lower prevalence of hypertriglyceridemia (9% versus 15%, P less than 0.05) than elderly whites. In elderly persons with hypertension, electrocardiographic left ventricular hypertrophy occurred in 19% of blacks and 14% of whites (P not significant), echocardiographic left ventricular hypertrophy occurred in 72% of blacks and 56% of whites (P less than 0.01), and concentric left ventricular hypertrophy occurred in 60% of blacks and 39% of whites (P less than 0.001).

Aronow et al. (1991) conducted a cohort in Coronary risk factors (n=1,414). Black race vs. White race was evaluated on Hypertension (p=<0.001). Elderly blacks had a higher prevalence of hypertension (50% vs 36%, P<0.001), diabetes (27% vs 19%, P<0.01), and obesity (11% vs 5%, P<0.005) compared to elderly whites.
