Awareness, treatment and blood pressure control in patients with hypertension.

<p>Definitions: Aware  =  respondents who self report to have hypertension, Treated  =  respondents who self report to have hypertension, and who indicate to take drug treatment for hypertension, Controlled  =  respondents who self report to have hypertension, and who have a blood pressure below 140/90 (patients who use drug treatment or for whom treatment status is unknown).</p

Hypertension prevalence and distribution of blood pressure.

<p>2A: Age-standardized and age stratified hypertension prevalence. 2B: Distribution of blood pressure in patients with hypertension (treated and untreated cases). Optimal  =  systolic blood pressure (SBP) <120 and diastolic blood pressure (DBP) <80; Normal  =  SBP 120–129 and/or DBP 80–84; Pre-HT (hypertension)  =  SBP 130–139 and/or DBP 85–89; Grade 1 =  SBP 140–159 and/or DBP 90–99; Grade 2 =  SBP 160–179 and/or DBP 100–109; Grade 3 =  SBP> = 180 and/or DBP> = 110.</p

Participation in the 4 surveys (household and individual level).

<p>*HH  =  households, **Repeating sampling done because household were difficult to locate due to poor registries used for sampling, ^†BP =  blood pressure.</p
