| Abstract

The purpose of the study was to explore the relationship between health literacy, hypertension-specific knowledge, patient activation, adherence to hypertension treatment plans, blood pressure control, and other important demographic factors (i.e. age, gender, comorbidity, education, and income). Additionally, this study examined whether hypertension-specific knowledge mediates the relationship between health literacy and patient activation. A descriptive, correlational design was used in this cross-sectional study. Data were collected using The Short-Test of Functional Health Literacy in Adults, the Brief Health Literacy Screen, the Hypertension Knowledge-Level Scale, the 13-item Patient Activation Measure, and the Hill-Bone Compliance to High Blood Pressure Therapy. The participants of this study involved 114 patients diagnosed with hypertension. The sample was drawn from primary healthcare centers in Riyadh, Saudi Arabia. Pearson correlations revealed that greater hypertension-specific knowledge and better adherence to hypertension treatment plans were significantly associated with lower systolic and diastolic blood pressure. Furthermore, age and gender were significantly correlated with patient activation, adherence to hypertension treatment plans, and diastolic blood pressure; education and income with health literacy. Additionally, adherence was significantly correlated in a positive direction with education and income. In the hierarchical regression analysis, 37% of the variance in adherence to hypertension treatment plans was explained, primarily by hypertension-specific knowledge and age. Accordingly, adherence to hypertension treatment plans was found to be a significant predictor and explained 26% of the variance in systolic blood pressure and %30 of the variance in diastolic blood pressure. Statistical analysis for logistic regression revealed that several independent variables/covariates were found to be significant predictors the dichotomous outcomes: higher/lower a) systolic and b) diastolic blood pressure. Participants with better adherence were 1.39 times more likely to be normotensive and have systolic blood pressure <140 mmHg. In addition, participants with greater disease knowledge were 1.30 times more likely to have lower systolic blood pressure. Conversely, Older participants were .91 times less likely to have normal systolic blood pressure. This work will be pivotal in devising self-management interventions to assist patients in the management of hypertension disease in Saudi Arabia.
