Among untreated adults, the burden of potentially modifiable risk factors for hypertension shows progressive increase along newly-defined pressure (BP) categories from the 2017 American College of Cardiology/American Heart Association (ACC/AHA) guidelines, a recent study found. Researchers analyzed data from the 1999-2014 National Health and Examination Survey (NHANES, n=37,448). Potentially modifiable risk factors included abdominal obesity, high non-HDL-cholesterol, secondhand smoking, binge drinking, suboptimal physical activity (PA), and low fiber diet. They found:
- The prevalence of certain modifiable risk factors decreased during the study period.
- However, the prevalence of low fiber intake, suboptimal PA, abdominal obesity, and binge drinking remined high during the last combined survey cycle.
- Modifiable risk factors generally demonstrated dose-response relationships with high BP categories.
- The most common type of risk factor clustering included low fiber intake, suboptimal PA, high non-HDL cholesterol and abdominal obesity, with its prevalence increasing gradually from 9.5% in the normal BP group to 16.5% in the state 2 hypertension group.
- The prevalence of ≥4 modifiable risk factors per participant increased stepwise.
