Description:The aim of this study is to describe trends in the awareness, treatment, and control of hypertension; mean blood pressure; and the classification of blood pressure among US adults 2003 to 2012. Using data from the National Health and Nutrition Examination Survey 2003 to 2012, a total of 9255 adult participants aged ≥18 years were identified as having hypertension, defined as measured blood pressure ≥140/90 mm Hg or taking prescription medication for hypertension. Awareness and treatment among hypertensive adults were ascertained via an interviewer administered questionnaire. Controlled hypertension among hypertensive adults was defined as systolic blood pressure <140 mm Hg and diastolic blood pressure <90 mm Hg. Blood pressure was categorized as optimal blood pressure, prehypertension, and stage I and stage II hypertension. Between 2003 and 2012, the percentage of adults with controlled hypertension increased (P-trend <0.01). Hypertensive adults with optimal blood pressure and with prehypertension increased from 13% to 19% and 27% to 33%, respectively (P-trend <0.01 for both groups). Among hypertensive adults who were taking antihypertensive medication, uncontrolled hypertension decreased from 38% to 30% (P-trend <0.01). Similarly, a decrease in mean systolic blood pressure was observed (P-trend <0.01); however, mean diastolic blood pressure remained unchanged. The trend in the control of blood pressure has improved among hypertensive adults resulting in a higher percentage with blood pressure at the optimal or prehypertension level and a lower percentage in stage I and stage II hypertension. Overall, mean systolic blood pressure decreased as did the prevalence of uncontrolled hypertension among the treated hypertensive population.
