QD: News Every Day--Hypertension prevalence stable, awareness of it improving but still poor


Prevalence of hypertension remained stable among men (30.5%) and women (28.5%) in the past decade, an analysis showed. Awareness, management, and control improved, but remained poor.

The study, which appeared in the Journal of the American College of Cardiology, used regression models to assess the trends in hypertension prevalence, awareness, management, and control from 1999 to 2010 among 29,000 men and women with blood pressure measurements from the National Health and Nutrition Examination Survey (NHANES).

From 1999 to 2010, the prevalence of hypertension remained stable. Although hypertension awareness, management, and control improved, the overall rates remained poor (74.0% for awareness, 71.6% for management, 46.5% for control, and 64.4% for control in management).

"Worse still, no improvement was shown from 2007 to 2010," the authors wrote.

The hypertension awareness rate was 69.7% (95% confidence interval [CI]; 62.0% to 77.4%) among men and 80.7% (95% CI: 74.5% to 86.8%) among women.

The hypertension control rate was 40.3% (95% CI: 33.7% to 46.9%) for men and 56.3% (95% CI: 49.2% to 63.3%) for women.

From 1999 to 2010, age-adjusted mean systolic blood pressure decreased by 4 mm Hg (P less than 0.001 for trend), especially for women (5 mm Hg; P less than 0.001 for trend). Mean diastolic blood pressure displayed a similar pattern, with a significant decrease of 3 mm Hg (P less than 0.001 for trend) and was significant for both men and women (P less than 0.001 for both). This result was comparable to other studies in the literature, the authors noted.
