Abstract

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.

Keywords: blood pressure; hypertension knowledge; medication adherence.

Resumen

Contexto: La hipertensión tiene una alta prevalencia en Vietnam, pero la tasa de hipertensión controlada sigue siendo baja. El conocimiento sobre la hipertensión está vinculado a las creencias del paciente y la adherencia a la medicación. Sin embargo, hay datos limitados sobre el conocimiento de la hipertensión entre los pacientes de atención primaria en Vietnam.

Objetivos: Evaluar el conocimiento sobre la hipertensión entre pacientes hipertensos en entornos de atención primaria en el centro de Vietnam e identificar factores que afectan su conocimiento.

Métodos: Se realizó un estudio transversal y un examen exhaustivo para evaluar el conocimiento sobre la hipertensión y sus factores relacionados. Utilizando la Escala de Nivel de Conocimiento sobre Hipertensión y la Escala de Informe de Adherencia a la Medicación, se evaluaron el conocimiento sobre hipertensión y la adherencia a la medicación. Además, se recopilaron datos demográficos, clínicos, de estilo de vida y de creencias de los pacientes. Se aplicaron análisis estadísticos y modelos de regresión logística para identificar factores clave asociados con el conocimiento sobre la hipertensión.

Resultados: En el estudio que involucró a 761 participantes (55,7% hombres), la puntuación promedio de conocimiento sobre hipertensión fue de 15,0 (DE = 4,6), y solo el 45,3% demostró un alto nivel de conocimiento. Se observaron correlaciones significativas entre el conocimiento sobre la hipertensión y variables como el nivel educativo, el origen étnico, el control de la presión arterial en el hogar, las creencias de los pacientes y la adherencia a la medicación. El análisis de regresión logística indicó que los niveles de educación más altos y la pertenencia a la etnia mayoritaria estaban relacionados con un mayor conocimiento sobre la hipertensión. En particular, las personas con mejores conocimientos sobre hipertensión tendían a reconocer la necesidad de los medicamentos recetados.

Conclusiones: El conocimiento sobre hipertensión entre los pacientes de atención primaria en el centro de Vietnam es subóptimo, y aproximadamente la mitad tiene un alto nivel de conocimiento. Estos hallazgos enfatizan la importancia del conocimiento sobre la hipertensión a la hora de moldear las creencias, percepciones y la adherencia a la medicación de los pacientes. Las intervenciones educativas personalizadas son cruciales, especialmente para aquellos con menor educación y antecedentes minoritarios, para mejorar el manejo de la hipertensión.

Palabras Clave: adherencia a la medicación; conocimientos sobre hipertensión; presión arterial.
