The age-adjusted prevalence of hypertension among U.S. residents ages 18 and older in 2011-12 was 29.1%, similar to the rate in 2009-10, according to a CDC report.
The prevalence was roughly equal for men and women, increased with age and was highest among non-Hispanic black adults, at 42.1%, according to the data brief by the CDCs National Center for Health Statistics.
Researchers used data from the National Health and Nutrition Examination Survey, 2011-2012, a a cross-sectional survey designed to monitor the health and nutritional status of the civilian noninstitutionalized U.S. population.
Among adults with hypertension, 82.7% were aware they had the condition, 75.6% were taking medication to lower their blood pressure and 51.8% had their condition controlled. There was no significant change in awareness, treatment and control from 2009-10 to 2011-12.
Women and older adults were more likely to have their hypertension controlled. Likelihood was similar across race and Hispanic origin groups.
Despite considerable improvement in increasing the awareness, treatment and control of hypertension, undiagnosed and uncontrolled hypertension among minority groups remains a challenge, the authors wrote.
The authors noted treatment of hypertension exceeded the Healthy People 2020 target goal of 69.5%, but hypertension control fell short of the 61.2% goal by 2020 and the Million Hearts Initiatives goal of a 65% control rate by 2017.
These results provide evidence for continued efforts to improve the management of hypertension in order to attain these goals, the authors wrote.
