About 72% of adults with hypertension were aware of their disease in 2017-2018; about three-quarters were treated for hypertension with medications (77%); and almost 68% were at controlled levels with these medicines (blood pressure <140/<90 mmHg).
Of those who had hypertension by either measured blood pressure or reported used of hypertensive medication, 71.6% were aware of their condition in 2017-2018. More than three-quarters (76.5%) of those participants who had measured blood pressure levels ≥140/ ≥90 mmHg were being treated for their condition through medication. Among participants with hypertension, who were being treated for their condition with medication, 67.7% had their condition under control with measured blood pressure levels <140/ <90 mmHg.
Hypertension is the second leading cause of chronic kidney disease (CKD). Hypertensive disease accounts for 28% of incident end-stage renal disease (ESRD) in the United States (United States Renal Data System, 2011). Hypertension is associated with higher risk of cardiovascular outcomes in those with CKD. Additionally, treatment of hypertension in CKD, particularly by ACE inhibitors, has been shown to decrease proteinuria and disease progression (Sarafidis et al., 2008). Thus, assessing the prevalence of this risk factor and its control is essential to CKD surveillance. The survey consists of a standardized in-home interview and a physical examination and blood and urine collection at a mobile examination center (MEC). Here we examined data from the 1999-2000, 2001-2002, 2003-2004, 2005-2006, 2007-2008, 2009-2010, 2011-2012, 2013-2014, 2015-2016 and 2017-2018 NHANES. Self-reported hypertension was defined by answer of “yes” to the question, “Have you ever been told by a doctor or other health professional that you have hypertension, or high blood pressure?” Blood pressure measurements were taken by standardized protocol during the MEC and the average value (up to four measurements) was used. Hypertension medications were recorded from prescription bottles during the interview.
