Key result
Audio-visual education boosts DASH diet knowledge scores by ~29 points in elderly hypertensive patients.
Why the study?
Knowledge regarding the DASH diet among the elderly remains low despite its proven effectiveness in lowering blood pressure.
Does health education improve knowledge of the DASH diet in elderly patients with hypertension?
Does health education improve knowledge of the DASH diet in elderly patients with hypertension?
Absolute Event Rate: 85.46% vs 56.77%
p-value: p=<0.001
Health education interventions are highly effective at improving knowledge of the DASH diet among elderly patients with hypertension.
May support audio-visual education for DASH knowledge gains in elderly hypertensives; leaves open effects on adherence or BP control.
Background. Hypertension is a common health problem among the elderly and can increase the risk of cardiovascular complications. Dietary approaches, particularly the Dietary Approaches to Stop Hypertension (DASH) diet, have been proven effective in lowering blood pressure. However, knowledge regarding this diet among the elderly remains low. This study aimed to analyze the effect of health education on improving knowledge of the DASH diet among the elderly. Objective. To determine the effect of health education on knowledge of Dietary Approaches to Stop Hypertension among the elderly at Ciwaruga Public Health Center. Methods. This study employed a quantitative research method with a quasi-experimental pretest–posttest one group design using a cross-sectional approach. The sampling technique used was purposive sampling, involving 52 respondents. The data were analyzed using the Wilcoxon test. The measurement instrument was a DASH (Dietary Approaches to Stop Hypertension) knowledge questionnaire. Results. The results of the Wilcoxon test showed a p-value < 0.001. Conclusions. There was a difference in DASH (Dietary Approaches to Stop Hypertension) knowledge before and after the health education intervention.

Aprilyana et al. (2026) studied Hypertension (n=52). Health education on the DASH diet vs. Pre-intervention baseline was evaluated on Knowledge of the Dietary Approaches to Stop Hypertension (DASH) diet (p=<0.001). Health education using audio-visual media significantly increased DASH diet knowledge among elderly patients with hypertension, improving average scores from 56.77 to 85.46 (p < 0.001).
