Hypertension Prevention and Healthy Life Expectancy in Black Adults: The Jackson Heart Study.

Background: The impact of preventing hypertension and maintaining normal blood pressure (BP) on life expectancy and healthy life expectancy (HLE) among Black adults, who are disproportionately affected by hypertension, has not been quantified.

Methods: We used a discrete event simulation to estimate life expectancy and HLE among a cohort of Black adults from the Jackson Heart Study (n=4933) from age 20 to 100 years or until death. We modeled preventing hypertension as having BP <130/80 mm Hg and maintaining normal BP as having BP <120/80 mm Hg across the lifespan.
