Trends in blood pressure control among US adults with hypertension

A series of cross-sectional studies investigated whether hypertension control, important for curtailing risk for cardiovascular disease, fluctuated among U.S. adults over the past 20 years. The analysis included 51,761 participants from the National Health and Nutrition Examination Survey, 18,262 of whom had high blood pressure.

A series of cross-sectional studies investigated whether hypertension control, important for curtailing risk for cardiovascular disease, fluctuated among U.S. adults over the past 20 years. The analysis included 51,761 participants from the National Health and Nutrition Examination Survey, 18,262 of whom had high blood pressure. Among them, the age-adjusted estimated proportion with controlled hypertension increased from 31.8% in 1999–2000 to 48.5% in 2007–2008. The percentage remained relatively stable, at 53.8%, through 2013–2014 but declined after that, falling to 43.7% by the end of the study period in 2017–2018. The results suggest that the prevalence of controlled blood pressure decreased among U.S. adults from 2013–2014 to 2017–2018. The sub-populations most likely to have the disease under control included adults aged 45–64 years vs. those aged 18–44 years; non-Hispanic whites vs. non-Hispanic Blacks; subscribers of private insurance vs. those with no coverage; patients with a usual health care facility vs. those without; and individuals who had a health care visit in the past year vs. those who did not.
