JAMA — Most Americans with high blood pressure aren’t doing enough to address it, according to a study published in the Journal of the American Medical Association on Monday.

The study found that two-thirds of US adults with uncontrolled blood pressure weren’t taking medication to treat it.

Researchers at the University of North Carolina specifically looked at people whose blood pressure was lower than 130 over 80, which is the threshold for Stage One hypertension.

The goal is to treat people when they’re in the elevated range of 121-129. A reading of 120 over 80 is considered normal.

Researchers at the University of North Carolina say most people can control their blood pressure with medication and lifestyle changes, which would substantially reduce their risk for cardiovascular disease and dementia.
