ObjectiveThe purpose of this study was to investigate the relationship between knowledge on arterial hypertension (AH) and its management, and adherence to pharmaceutical treatment.MethodsThe study included 233 patients diagnosed with AH and treated with hypotensive drugs for at least 1 year. The 8-item © Morisky Medication Adherence Scale (MMAS-8) and the Hypertension Knowledge-Level Scale (HK-LS) were used.ResultsSixty-three percent of the patients had a low level of knowledge on AH, with the smallest proportion of correct answers provided for items related to non-pharmaceutical treatment, diet, hypertension definition, and drug adherence. When compared to patients with a high level of knowledge, those with a low knowledge had lower scores in the MMAS (6.45±1.45 vs 7.08±1.04; P=0.038). Multiple-factor analysis showed that statistically significant independent determinants of good adherence included a high level of knowledge (β=0.208; P=0.001), non-pharmaceutical treatment (β=0.182; P=0.006), and frequent blood pressure measurements (β=0.183; P=0.004). The most significant factor in MMAS was knowledge in the “drug adherence” domain (ρ=0.303; P<0.001).ConclusionPatients’ knowledge on hypertension is a significant independent determinant of good adherence. Other independent determinants include non-pharmaceutical treatment and regular blood pressure measurements.Implication for practiceThe identification of knowledge deficits as a factor contributing to lack of adherence and poor hypertension control remains a key challenge for multidisciplinary team caring for patients with hypertension.

“…It seems that unhealthy behavior is rooted in misperceptions and incorrect knowledge of the nature of disease and its related nutritional issues, since poor knowledge of patients has been introduced as one of the reasons for the lack of blood pressure control [24, 25]. …”

Introduction and Objectives. Nutritional knowledge of the patients is important in dietary adherence. This study aimed to determine the relationship between illness perceptions and nutritional knowledge with the amounts of sodium intake among rural hypertensive patients. Methods. In a cross-sectional study, 671 hypertensive patients were selected in a multistage random sampling from the rural areas of Ardabil city, Iran, in 2013. Data were collected using a questionnaire consisting of four sections and were analyzed using Pearson correlation and multiple linear regressions by SPSS-18. Results. The mean of sodium intake in the uncontrolled hypertensive patients was 3599 ± 258 mg/day and significantly greater than controlled group (2654 ± 540 mg/day) (P < 0.001). Knowledge and illness perceptions could predict 47.2% of the variation in sodium intake of uncontrolled group. A significant negative relationship was found between knowledge and illness perceptions of uncontrolled hypertensive patients with dietary sodium intake (r = −0.66, P < 0.001 and r = −0.65, P < 0.001, resp.). Conclusion. Considering the fact that patients' nutritional knowledge and illness perceptions could highly predict their sodium intake, the importance of paying more attention to improve patients' information and perceptions about hypertension is undeniable, especially among the uncontrolled hypertensive patients.

“…Therapeutic drug adherence was evaluated using the Morisky 8-items questionnaire [12], assessment of high blood pressure related knowledge was done with the Hypertension Knowledge Level Scale, while the quality of the diet was evaluated with the food evaluation questionnaire [13] [14], and the Karasek questionnaire (validated French version) was used to estimate the level of stress in professional environment [15].…”

Background: Hypertension is the leading cardiovascular risk factor worldwide, with the greatest burden in low-income settings. Blood pressure (BP) control is usually low resulting in high rates of uncontrolled patients and complications. Low awareness resulting in poor therapeutic adherence represents an important factor for insufficient blood pressure control in developing countries. Methods: This was a three months non-randomized control trial at the cardiology clinic of the Yaoundé Central Hospital. We included adults with essential and uncontrolled hypertension. The intervention consisted of group educative sessions every week focusing on knowledge of hypertension risk factors, complications, treatment, comorbidities, home self-monitoring of BP. Home blood pressure figures, drug compliance, and knowledge regarding hypertension were evaluated before and after. Results: 17 participants (8 women) with a mean age 56.2 ± 8.1 years. During intervention, mean SBP decreased by 30 mmHg while mean DBP drooped by 11 mmHg using home BP measures. Knowledge regarding hypertension, adherence and drug compliance increased by 36.5%, 88.2% and 81.4% respectively. Conclusion: Therapeutic group education resulted in a significant improvement in BP control amongst uncontrolled hypertensive patients in sub Saharan Africa.
