Abstract
Background: High Blood Pressure (HBP) is high prevalent among adult population in Bamako, but little is known about factors associated with knowledge. Methods: It was a cross-sectional study involving patients aged 15 years and more with a first classification in normal blood pressure (HTN-) and high blood pressure (HTN+), and Second classification inpatients without knowledge (who answered No) (K-) and patients with knowledge (who answered Yes) (K+). A logistic regression was performed to look up predictors among different variables. Results: The sample involved 456 patients with a mean age of 51.39 years and 65.1% of female. The age group 45 - 59 years old made 32.5% and unschooled patients 60.3%. Patients with HBP accounted for 69.7% and those reporting to know about it 67.3%. HTN- and HTN+ differed significantly except for HR, height, sex and level of schooling. HBP prevalence increased with age up to 74 years. Regarding knowledge, sex, age group and number of FDRs did not differ significantly. High education level and duration of HBP was predictive of knowledge with an OR of 1.186 [CI 0.058 - 0.796] and 1.192 [CI 0.332 - 4.275] respectively. Conclusions: Our study provided data on HBP knowledge among outpatients with high educational level and HBP duration associated with better knowledge on HBP.

Summary
Hypertension (HTN), a major cardiovascular risk factor, is a global public health problem with nearly 25% prevalence in 2000. Other authors found that unawareness differs by sex [7] Common to all these studies is the use of either self reported health information or administrated formularies in survey. Factors known to be associated with awareness, knowledge of HTN are family history of HTN, overweight, worker status [8], marital status, education, health status, periodically reading books, newspapers or other materials, history of blood pressure measurement, and attending hypertension educational sessions [9]. There is a lack of data on HTN knowledge determinants which must be considered in decisions for HTN prevention and management. These facts have motivated our study which aims to study knowledge about hypertension as well as factors associated with this knowledge
