Gu A, et al. - This study draws on data from the 1999-2014 National Health and Nutrition Examination Survey to assess the burden of potentially modifiable risk factors of hypertension (abdominal obesity, high non-HDL cholesterol, secondhand smoking, binge drinking, suboptimal physical activity and low fiber diet) among untreated adults in the newly defined categories of blood pressure. According to the findings, the burden of potentially modifiable risk factors for hypertension displayed progressive increases along the blood pressure categories and represented an important target for non-pharmacologic intervention. Researchers reported that the most common type of risk factor clustering included low fiber intake, suboptimal physical activity, high non-HDL cholesterol and abdominal obesity, with its prevalence increasing gradually from 9.5% in the normal blood pressure group to 16.5% in stage 2 hypertension group.
