ABSTRACT

Background: High blood pressure is a risk factor for cardiovascular disease. Beets have various vitamins, minerals, fiber, folate, mangan, and nitrate. Nitrate in the body is converted into biologically active nitrite and nitric oxide. Nitric oxide can help relax and dilate blood vessels. This study aimed to determine the effect of beet sugar (Beta Vulgaris. L) in lowering high blood pressure among the elderly.

Subjects and Method: This was a quasi-experiment study one group before after with no control design carried out at Gunungan Integrated Health Post Elderly, Pleret, Yogyakarta. A sample of 22 elderly aged ≥ 56 years old was selected for this study. The dependent variable was blood pressure. The independent variable was consumption of 200 ml of beet juice for 6 days in a row. Blood pressure was measured by sphygmomanometer. The data were analyzed by paired t-test.

Results: Systolic blood pressure after intervention (Mean= 155.00; SD= 21.46) was lower than before intervention (Mean= 170.86; SD= 25.67) and it was statistically significant (p<0.001). Diastolic blood pressure after intervention (Mean= 92.54; SD= 12.14) was lower than before intervention (Mean= 97.54; SD= 12.88) and it was statistically significant (p=0.014). This reduction, however, was not large enough to reach the minimum clinically meaningful blood pressure level, i.e. 140 mmHg for systolic blood pressure and 90 mmHg for diastolic blood pressure.

Conclusion: Beet sugar decreases both systolic and diastolic blood pressures among the elderly, but this reduction is not large enough to reach the minimum recommended blood pressure level. Further studies are recommended to address this research question using randomized control trial (RCT) to provide stronger evidence.

Keywords: beet sugar, systolic, diastolic, blood pressure, hypertension, elderly.
