Abstract / Summary
Treatment adherence is a pivotal component of hypertension management. A large number of hypertensive patients do not adhere to their treatment regimen. This study aimed to identify the predictors of treatment adherence among hypertensive patients. This multicenter cross-sectional study was conducted between November 2025 and January 2026 in northwestern Iran. Five hundred eligible hypertensive patients were selected using a clustered random sampling method. Data were collected using a demographic questionnaire, the Patient Activation Measure (PAM), and the Treatment Adherence Questionnaire for Patients with Hypertension (TAQPH). Data were analyzed using descriptive and inferential statistics. SPSS ver.21 software was used for data analysis. The Mean ± SD of treatment adherence was 88.44 ± 7.01. It was found that treatment adherence had a direct correlation with patient activation. Also, a negative correlation was detected between treatment adherence with blood pressure and duration of disease. The multiple linear regression model revealed that patient activation, SBP, physical activity, education, history of smoking, and abdominal diameter were the main predictors of treatment adherence (adjusted R square = 0.66). Hypertensive patients’ treatment adherence is good but not optimal. Based on the results, improvement of patient activation should be prioritized. Also, weight loss, daily activity, and quitting smoking are recommended.
