Abstract

Background: Hypertension is a common chronic condition that can lead to serious complications if not properly and adequately treated. Medication adherence plays a crucial role in blood pressure control and the prevention of complications. Objectives: To determine the rate of medication adherence and its associated factors among hypertensive outpatients at Giong Trom District Medical Area, Vinh Long province, during 2023–2025. Materials and method: A cross-sectional descriptive study was conducted using retrospective data from 400 outpatients aged over 18 years receiving antihypertensive treatment. Systematic random sampling was applied. Logistic regression was used to analyze associated factors. Results: The non-adherence rate was 93.0%. Statistically significant associations were found between medication adherence and the following factors: adequate intake of vegetables and fruits (OR = 3.89; p = 0.040), non-smoking status (OR = 12.3; p = 0.005), and adherence to regular follow-up visits (OR = 1.11; p = 0.016). Patients aged 40–59 and male patients were more likely to have poor adherence (p < 0.05). Conclusion: The rate of medication adherence among hypertensive patients was low. Behavioral and lifestyle interventions, especially for men and middle-aged individuals, are essential to improve treatment effectiveness.
