Prevalence, awareness, treatment and control of hypertension in the Palestinian population.

We determined the prevalence of hypertension and the level of awareness, treatment and control of hypertension among Palestinian adults in a population-based cross-sectional survey. Two-stage stratified sampling method was used to select 2077 participants from the general population aged 25 years and over. Trained observers obtained two blood pressure (BP) measurements from each individual by the use of a standardized mercury sphygmomanometer after a 5-min sitting rest. Information on sociogeographical factors and antihypertensive medications was obtained using a standard questionnaire. Hypertension was defined as a mean systolic BP (SBP) 140 mm Hg, diastolic BP (DBP) 90 mm Hg, and/or use of antihypertensive medications. The overall prevalence of hypertension was 27.6%, with a higher percentage among men (29.2 vs 26.4%; P=0.04). Hypertension increased with age in both men and women. Among hypertensive patients, 51.0% were aware of their elevated BP, 40.2% had treatment and only 9.5% achieved targeted BP control (<140/90 mm Hg). Patients under antihypertensive treatment showed SBP and DBP that were only 3.1 mm Hg and 2.5 mm Hg lower than individuals without antihypertensive treatment, respectively. The data show that hypertension prevalence among Palestinian adults is high, whereas the proportions of awareness treatment and control of hypertension were low. Concerted public health effort is urgently required to improve the detection, treatment and control of hypertension in Palestine.
