<![CDATA[Background: Hypertension, or high blood pressure, is often referred to as "the silent killer" because it often occurs without symptoms. The non-pharmacological therapy approach, the Dietary Approach to Stop Hypertension (DASH), is highly effective in reducing hypertension. Purpose: To determine the effectiveness of audiovisual-based DASH education on knowledge and attitudes about blood pressure control in elderly hypertensive patients. Method: This study used a quasi-experimental design with a pretest-posttest nonequivalent control group design. The subjects were hypertensive patients at the Baciro Village Elderly Health Post (Posyandu Lansia) and the Ngudi Waluyo Elderly Health Post (Posyandu Lansia) in the intervention group, with a total of 47 elderly hypertensive patients. Data were analyzed using independent sample t-tests and Wilcoxon tests. Results: The DASH diet education for hypertension patients achieved a p-value of 0.001 in the intervention group. A one-week follow-up showed an increase in knowledge scores of 43 participants (91.5%) and attitudes toward the DASH diet in 43 participants (89.4%) with a p-value <0.05. Conclusion: DASH diet education using audiovisual media is effective in changing the knowledge and attitudes of people with hypertension.
