Prevalence of Heart Disease and Stroke Risk Factors in Persons With Prehypertension in the United States, 1999-2000
Key result
Persons with prehypertension were 1.65 times more likely to have at least 1 other adverse cardiovascular risk factor compared to those with normotension (P<.001).
Why the study?
Is prehypertension associated with a higher prevalence of other cardiovascular risk factors compared to normotension in US adults?
Population
3,488 persons aged 20 years and older with blood pressure measured in the 1999-2000 National Health and…

Effect estimate: OR 1.65
p-value: p=<.001
Prehypertension is highly prevalent and significantly associated with other cardiovascular risk factors, highlighting the need for early detection and comprehensive preventive efforts.

Greenlund et al. (2004) conducted a cross-sectional in Prehypertension (n=3,488). Prehypertension vs. Normotension was evaluated on Presence of at least 1 other adverse risk factor (OR 1.65, p=<.001). Persons with prehypertension were 1.65 times more likely to have at least 1 other adverse cardiovascular risk factor compared to those with normotension (P<.001).
