摘 要：Hypertension affects one third of adults in the United States (1) and is a major risk factor for heart disease and stroke (2). A previous report found differences in the prevalence of hypertension among racial/ethnic populations in the United States; blacks had a higher prevalence of hypertension, and Hispanics had the lowest use of antihypertensive medication (3). Recent variations in geographic differences in hypertension prevalence in the United States are less well known (4). To assess state-level trends in self-reported hypertension and treatment among U.S. adults, CDC analyzed 20052009 data from the Behavioral Risk Factor Surveillance System (BRFSS). The results indicated wide variation among states in the prevalence of self-reported diagnosed hypertension and use of antihypertensive medications. In 2009, the age-adjusted prevalence of self-reported hypertension ranged from 20.9% in Minnesota to 35.9% in Mississippi. The proportion reporting use of antihypertensive medications among those who reported hypertension ranged from 52.3% in California to 74.1% in Tennessee.
