Self-reported hypertension and use of antihypertensive medication among adults - United States, 2005-2009

Abstract

Hypertension affects one third of adults in the United States and is a major risk factor for heart disease and stroke. 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. Recent variations in geographic differences in hypertension prevalence in the United States are less well known. To assess state-level trends in self-reported hypertension and treatment among U.S. adults, CDC analyzed 2005-2009 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. From 2005 to 2009, nearly all states had an increased prevalence of self-reported hypertension, with percentage-point increases ranging from 0.2 for Virginia (from 26.9% to 27.1%) to 7.0 for Kentucky (from 27.5% to 34.5%). Overall, from 2005 to 2009, the prevalence of self-reported hypertension among U.S. adults increased from 25.8% to 28.3%. Among those reporting hypertension, the proportion using antihypertensive medications increased from 61.1% to 62.6%. Increased knowledge of the differences in self-reported prevalence of hypertension and use of antihypertensive medications by state can help in guiding programs to prevent heart disease, stroke, and other complications of uncontrolled hypertension, including those conducted by state and local public health agencies and health-care providers.
