Context: Hypertension is highly prevalent in Vietnam, yet the rate of controlled hypertension remains low. Knowledge about hypertension is linked to patient beliefs and medication adherence. However, there's limited data on hypertension knowledge among primary care patients in Vietnam. Aims: To evaluate the knowledge of hypertension among hypertensive patients in primary care settings in Central Vietnam and identify factors affecting their knowledge. Methods: A cross-sectional study was conducted, and a thorough examination was performed to assess hypertension knowledge and its related factors. Utilizing the Hypertension Knowledge Level Scale and Medication Adherence Report Scale, hypertension knowledge and medication adherence were evaluated. Additionally, demographic, clinical, lifestyle, and patient belief data were gathered. Statistical analyses and logistic regression models were applied to pinpoint key factors associated with hypertension knowledge. Results: In the study involving 761 participants (55.7% male), the average hypertension knowledge score was 15.0 (SD = 4.6), with only 45.3% demonstrating a high level of knowledge. Significant correlations were observed between hypertension knowledge and variables such as education level, ethnicity, home blood pressure monitoring, patient beliefs, and medication adherence. Logistic regression analysis indicated that higher education levels and belonging to the majority ethnicity were linked to enhanced hypertension knowledge. Notably, individuals with better hypertension knowledge tended to recognize the necessity of their prescribed medications. Conclusions: Hypertension knowledge among primary care patients in Central Vietnam is suboptimal, with approximately half having a high knowledge level. These findings emphasize the importance of hypertension knowledge in shaping patient beliefs, perceptions, and medication adherence. Tailored educational interventions are crucial, especially for those with lower education and minority backgrounds, to enhance hypertension management.
