Self-reported Hypertension on a Caribbean Island

BACKGROUND: Although current guidelines emphasize the importance of hypertension knowledge, little is known about accuracy of this knowledge, factors affecting accuracy and the relationship of self-reported hypertension with cardiovascular disease (CVD). METHODS: One hundred and forty seven subjects were asked to provide self-reported data on hypertension. RESULTS: These were correlated with levels of systolic and diastolic hypertension measures. Demographic characteristics were considered as determinants of awareness and accuracy. Women were more likely than men to be aware of their hypertension levels. However men were more likely to exercise, use salt, smoke and consume alcohol. Women were more likely to be hypertensive, nonsmokers, and moderate drinkers. Higher levels of self-reported hypertension were strongly associated with increased risk of CVD. Women that smoke, have untreated hypertension, or a sedentary lifestyle have a decrease in awareness of their hypertension levels. CONCLUSIONS: Self-reported hypertension underestimates measured values, but is strongly related to CVD. Lack of awareness of elevated hypertension is associated with increased risk of CVD.
