Correlation of Serum Sodium Levels with Blood Pressure in Adolescents in Amurang, South Minahasa District

Sodium intake is very important in the mechanism of increasing blood pressure [1]. The effect of sodium intake in increasing blood pressure is through an increase in plasma volume (body fluid) and blood pressure [2]. The research was conducted in the form of an analytic survey with a cross-sectional study design. The data were processed using the SPSS program. The population is all students of SMAN 1 Amurang, South Minahasa District, the sample is taken by total sampling. From 67 samples, the minimum sodium content was 137 mEq/L and the maximum sodium content was 164. The average Na content was 143.54 mEq/L. The average systolic blood pressure was 119.04 mmHg and the average diastolic blood pressure was 79.70 mmHg. Based on the results of the Spearman correlation test, the correlation coefficient value (R = 0.069) with a significance of 0.579 for the correlation between sodium levels and systolic pressure. These results indicate that there is no statistically significant relationship between Na levels and systolic blood pressure. For the other Spearman correlation test results, the correlation coefficient value (R=-0.089) with a significance of 0.473 for the correlation between sodium levels and diastolic pressure. These results also show that there is no statistically significant relationship between sodium levels and diastolic blood pressure. It can be concluded that there is no relationship between serum sodium levels and blood pressure in adolescents in Amurang, South Minahasa District.
