Hypertension, known as the silent killer, is a major risk factor for cardiovascular disease. Awareness and treatment of hypertension is not appropriate in the world, and this has led to an increase in mortality and morbidity caused by uncontrolled hypertension. This study aims to estimate awareness, treated, and controlled hypertensive and relevant predictors in an adult Iranian population. This cross-sectional study was conducted on 10,000 adults aged 20-69 years in Yazd, Iran. They were selected through multi-stage random cluster sampling in 2015-2016. Blood pressure was measured three-time with standard protocol by trained health workers. Those with a positive history of hypertension and using anti-hypertensive drugs, prescribed by a physician, were considered hypertensive. Hypertension was defined as systolic blood pressure ≥ 140 mmHg and/or diastolic BP of ≥90 mmHg. Uncontrolled hypertension was defined in accordance with recommended treatment targets by the Joint National Committee (JNC7). Logistic regression was used to assess the predictors of hypertension awareness, treatment and control. The prevalence of hypertension was 37.3%, and the prevalence of pre-hypertension was 46.4%. 49.7% of People with hypertension were aware of their disease, and 71.5% of them were using antihypertensive drugs prescribed by physicians. Blood pressure was controlled in 38.9% of the treated patients. In the adjusted model, older age, female sex, and history of diabetes mellitus were positively associated with higher awareness. High physical activity, tobacco smoking, and diabetes are the only predictors of treated high blood pressure. Younger age, female sex, and higher education were determinants of controlled hypertension. Having health insurance was significantly correlated with awareness and control of hypertension. Hypertension is a public health problem in this population, which is not well controlled. Half of the patients were unaware. Intervention for increased screening coverage is needed. It should plan to raise public awareness about hypertension and improve hypertension control under the supervision of physicians. Implement a family physician program is recommended in the health system.
