An additional 59 million adults have prehypertension, a level that is above normal, and increases risk of heart disease and stroke. Results of the study, called PREMIER, appear in the April 4, 2006 issue of Annals of Internal Medicine.
"This study underscores the value of lifestyle changes--namely improving diet and increasing physical activity--in reducing high blood pressure, an important public health problem," said NHLBI Director Elizabeth G.
