ABSTRACT

Background: Dietary Approaches to Stop Hypertension (DASH) is an eating plan to lower or control high blood pressure. The DASH diet emphasizes foods that are lower in sodium as well as foods that are rich in potassium, magnesium, and calcium- nutrients that help lower blood pressure. This study aimed to determine the effect of DASH on reducing blood pressure in the elderly with hypertension.

Subjects and Methods: This was a randomized controlled trial (RCT) conducted at Graha Wreda Marie Joseph, Siantan, Pontianak, West Borneo,  from April 10 to May 10, 2021. A sample of 30 older people with hypertension was selected for this study, and then assigned at random into two groups: (1) 15 patients in  the experimental group who underwent DASH; and (2) 15 patients in the control group who did not undergo DASH. The dependent variables were systolic and diastolic blood pressures. The independent variable was DASH. DASH was an eating plan applied at breakfast, lunch, and dinner, that lasted for 30 days. The mean difference of both systolic and diastolic blood pressures after DASH intervention between the experimental and control group was tested by independent t-test.

Results: The mean systolic blood pressure in the experimental group (Mean= 128.33; SD= 18.94) was lower than that in the control group (Mean= 145.20; SD= 25.63), and it was statistically significant (p= 0.027). Likewise, the mean diastolic blood pressure in the experimental group (Mean= 78.00; SD = 8.27) was lower than that in the control group (Mean= 84.07; SD= 6.45), and it was statistically significant (p= 0.043).

Conclusion: Dietary Approach to Stop Hypertension is effective to reduce systolic and diastolic blood pressures in the elderly with hypertension.
