HUBUNGAN PENGETAHUAN DIET DASH DENGAN KEPATUHAN DIET PADA PASIEN HIPERTENSI

Abstract

The increasing number of hypertension patients is attributed to insufficient public knowledge about hypertension management, particularly regarding lifestyle control through dietary patterns. One method to control hypertension by altering lifestyle involves adopting the DASH dietary approach. Adequate knowledge of the DASH method can encourage better behavioral practices. This study aims to investigate the relationship between knowledge of the DASH diet and dietary adherence among hypertensive patients at the Internal Medicine Clinic of Singasana General Hospital. The study was conducted using a quantitative design with an analytical observational approach and a cross-sectional design, carried out from February to March 2025 with a sample size of 78 respondents selected using consecutive sampling. Data were collected using a DASH diet knowledge questionnaire and a DASH diet adherence questionnaire. Data were analyzed using Spearman's rho test with p<0.05.  The results showed that the majority had insufficient knowledge (61.5%) and the majority were non-compliant with the diet (73.1%). Analyzing the relationship between DASH diet knowledge and dietary compliance in hypertensive patients using Spearman's rho yielded a p-value <0.001, indicating a significant relationship between DASH diet knowledge and dietary compliance in hypertensive patients at the internal medicine clinic of Singasana General Hospital. It is hoped that the recommendations of this study will motivate patients to seek knowledge about the DASH diet through various media, thereby increasing their knowledge and adherence to the diet.
