Abstract
PURPOSE: Effective management of hypertension requires consistent and long-term therapy. In Indonesia, the association between medication information from healthcare providers and adherence to antihypertensive therapy has not been examined. This study aimed to analyze the relationship between receiving antihypertensive medication information and medication adherence among adults with hypertension in Indonesia. METHODS: A cross-sectional analysis was conducted using secondary data from the 2023 Indonesian Health Survey. Baseline characteristics were described using descriptive statistics. Medication non-adherence, receipt of antihypertensive medication information, and potential confounders such as gender, age, education level, marital status, occupation, and island of residence were assessed through self-reported single-item measures. The association between lack of information and medication non-adherence was examined using binary logistic regression adjusted for confounders. Both Crude (COR) and Adjusted Odds ratios (AORs) with corresponding 95% confidence intervals (CIs) were reported. RESULTS: Among 53,668 patients, most were female (66.3%), married (77.4%), aged over 35 years (95.3%), and unemployed (40.9%). The majority (68.1%) had received information emphasizing the need for regular antihypertensive medication. A lack of information about the necessity of long-term antihypertensive treatment was significantly associated with medication non-adherence (AOR=5.05; 95% CI=4.84-5.26). CONCLUSION: This study demonstrates a strong association between a lack of information regarding long-term antihypertensive medication and non-adherence among hypertensive patients in Indonesia. Therefore, there is a need for improved communication strategies between patients and healthcare providers to improve long-term medication adherence.
