Trends in Blood Pressure and Hypertension Detection, Treatment and Control 1980-2009: The Minnesota Heart Survey
Background—Hypertension is common and treatable but detection and control remain a major health challenge. This study sought to determine population trends in blood pressure and in the control of hypertension in the Minneapolis/St. Paul area (2010 population: 2.85 million) from 1980-2009.
Methods and Results—Surveys of risk factors were carried out every five years among randomly selected adults aged 25-74. Data on hypertension knowledge and use of medications were collected by interview. Blood pressure was measured using standardized methods with hypertension defined as blood pressure ≥140 and/or 90 mmHg or controlled (<140 and/or 90mmHg) on medications. Six surveys included 11,192 men and 12,795 women. Mean systolic blood pressure (SBP) fell from 124.9 mmHg in 1980-82 to 121.1 mmHg in 2007-09 for men (p<.0001) and for women from 120.1 mmHg to 114.7 mmHg (p<.0001). Similar trends for diastolic blood pressure were observed. Adults with uncontrolled blood pressure (≥140 and/or 90 mmHg) with or without medication fell from 20.3% to 5.8% (p<.001) for men and 13.1% to 2.7% (p<.0001) for women. Anti-hypertensive medication use rose to over 50% among all adults aged 55-74. Men (66%) and women (72%) with hypertension were treated and controlled by 2007-09. A majority of the decline in mean population blood pressure was the result of control with aggressive use of anti-hypertensive drugs. Stroke mortality in this population fell in parallel.
Conclusions—Hypertension detection and control in this community is among the highest observed in a US population and already exceeds Health People 2020 goals.
