Prevalence, awareness, treatment, control and risk factors associated with hypertension in Lebanese adults: A cross sectional study

Abstract

Background: The prevention and control of hypertension is an essential component for reducing cardiovascular disease burden. Hypertension is an important public health issue, yet few studies have examined its current status among the Lebanese population. Objective: To examine the prevalence, awareness, treatment and control of hypertension and its associated risk factors among Lebanese adults. Methods: A cross-sectional study was conducted between December 2014, and May 2015, on adults from the five districts of Lebanon. Multistage sampling was used to enroll participants. Hypertension was defined as an average of two blood pressure (BP) measurements with systolic/diastolic blood pressure of at least 140/90 mm Hg, using an automated digital device, or the use of antihypertensive medication. A questionnaire was used to assess hypertension risk factors, awareness, treatment and control. Results: Of the 1362 Lebanese adults interviewed, 399 (29.3%) had hypertension. Of these, 106 (26.5%) were aware of their condition. Sixty-nine patients (65%) of those aware, were receiving treatment, and 38 (55%) participants from those treated were controlled. The significant risk factors were sex, gender, age, family history of hypertension, obesity, and a low level of education. Conclusions: Hypertension is prevalent among the Lebanese adult population and is multifactorial, but remains incompletely recognized, leading to insufficient control. Hypertension was highly prevalent in males in the age category 18-29 years. These findings show that improvements in detection, treatment, and control of hypertension among Lebanese adults, is much needed.
