Independent predictors of effective blood pressure control in patients with hypertension on drug treatment in Brazil.

Abstract

Population assessment of effective blood pressure (BP) control is fundamental for reducing the global burden of hypertension, especially in low- and middle-income countries. The authors evaluated the effectiveness of BP control and determined independent predictors associated with effective control among patients with hypertension on drug treatment in a large cross-sectional study performed in two metropolitan areas in Brazil's southeast region. A total of 43647 patients taking antihypertensive treatment were identified. Less than half of the patients (40.9%) had controlled BP (systolic BP <140mm Hg and diastolic BP <90mm Hg). Independent predictors of BP control were age, eating fruit daily, physical activity, previous cardiovascular disease, male sex, diabetes mellitus, ethnicity, and obesity. Simple variables associated with BP control may be utilized for knowledge translation strategies aiming to reduce the burden of hypertension.
