R. Bloomfield et al., RACIAL-DIFFERENCES IN PERCEPTIONS CONCERNING HYPERTENSION AND ITS CONSEQUENCES, Southern medical journal, 86(7), 1993, pp. 767-770
To investigate racial differences in hypertensive patients' understand
ing of their disorder, we administered a questionnaire to 83 black and
260 white outpatients with the diagnosis of hypertension designated i
n their medical chart. No racial differences in systolic or diastolic
blood pressure, age, or male/female ratio were observed. However, blac
ks were more likely than whites to identify renal failure as a consequ
ence of hypertension, whereas whites were more likely to identify athe
rosclerosis. Blacks also were more likely than whites to accept higher
diastolic blood pressures as normal (90 to 100 mm Hg versus 80 to 90
mm Hg). There was no correlation between knowledge and blood pressure.
Our observations show that both racial groups are well educated about
antihypertensive therapy as well as the consequences and complication
s of hypertension. Comprehensive treatment of hypertension should incl
ude educational strategies that are population-specific and that addre
ss ways to change disease-relevant behaviors, rather than merely ident
ifying which behaviors to change.
