A significant number of Americans are facing issues with blood pressure, yet many aren’t taking steps to address it, according to new research released today.
The study analyzed data from Americans over 20 years old, revealing that nearly 80% of those with hypertension aren’t managing it effectively. Alarmingly, a considerable portion of individuals with uncontrolled hypertension aren’t using any medication to lower their blood pressure. The researchers emphasize that these medications could greatly benefit cardiovascular health, as long as individuals are open to receiving treatment.
“Many could potentially achieve control of their blood pressure with the start of antihypertensive medication and lifestyle changes,” the researchers mentioned in their study, published recently in JAMA.
Silent but serious
Hypertension is characterized by having a systolic blood pressure of 140 mm Hg or more and a diastolic pressure of 90 mm Hg or more. It is labeled as uncontrolled when untreated or when blood pressure stays high despite treatment.
Often, high blood pressure doesn’t present noticeable symptoms. However, if left unmanaged, it can increase the risk of severe health issues like heart attacks, strokes, and kidney disease. The Centers for Disease Control and Prevention noted that hypertension was linked to 664,470 deaths in the U.S. in 2023.
The American Heart Association advises a combination of lifestyle modifications and medication to lower blood pressure for those with hypertension to below 130/80. To better understand how many Americans are failing to meet this target and the reasons behind it, researchers reviewed data from the National Health and Nutrition Examination Survey (NHANES), which provides insights into Americans’ diet and lifestyle habits.
From 2021 to 2023, NHANES data showed that 47% of Americans had hypertension, with 79% experiencing uncontrolled blood pressure during that period. Among those with uncontrolled hypertension, around 61% reported not being on any medication.
Mixed messages
While some individuals may still struggle with hypertension even when treated, higher national adoption of medications could have a significant impact. The researchers noted that two-thirds of those with uncontrolled blood pressure were within 10 points of the recommended target, suggesting many could achieve it with adequate assistance. There also seem to be practical ways to begin closing this gap.
Interestingly, most individuals with untreated hypertension had health insurance or regular access to healthcare (over 80%), but these rates were notably lower compared to those with controlled hypertension. For some, it might just be an issue of awareness. A 2024 study revealed that 40% of Americans with hypertension were unaware they had the condition, while many struggle to interpret their blood pressure readings correctly.
If you think you may have hypertension, or it has been a while since your last blood pressure check, it’s a good idea to get screened during your next doctor’s appointment.
