High blood pressure is caused by retention of sodium in the blood. Potassium can lower blood pressure by causing vasodilatation effect, thus decreasing total peripheral and increasing cardiac output. Magnesium is a nutrient for heart health that helps the heart muscle to relaxation. People with more body weight, show the blood pressure tend to be higher than thin. The prevalence of hypertension in Makamhaji village is 23%. To determine the relationship among the intake of sodium, potassium, magnesium and nutritional status with blood pressure of the elderly in theMakamhaji village. The research was an observational with cross-sectional approach. Subject of the research is 40 individuals selected by using multistage sampling. Data of sodium, potassium, and magnesium intake were obtained using recall. Data of nutritional status were acquired using body mass index. The blood pressure was measured using Sphigmomanometer. Data were analyzed using correlation test of Pearson Product Moment. The result research indicated that respondents with a high sodium intake as much as 40%, low potassium intake as much as 57,5%, then, less magnesium intake as much as 47,5%. Respondents with lack nutritional status were 25%. 30% respondents displayed a mild systole high blood pressure and were 60% respondents displayed a mild diastole high blood pressure. The Pearson Product Moment revealed the correlation between sodium intake and blood pressure with p value = 0.006. Potassium intake and blood pressure gave the correlation with p value = 0.019. Thus magnesium intake and blood pressure displayed a relation with p value = 0.029. Then the nutritional status showed the correlation with blood pressure p = 0.013. There are correlation among intake of sodium, potassium, magnesium and nutritional status with blood pressure of the elderly in the Makamhaji village.
