Abstract

This study was conducted to examine the effects of Na, K intake and stress level on the blood pressure and urinary excretion of Na, K in the third grade lacto-ovo vegetable male high school students. Twenty-one lacto-ovo vegetarian male high school students were selected, and their physical state, stress level, dietary intake and urinary excretion of Na, K were measured followed by examining the relationship among these factors and blood pressure. The results of the study can be summarized as follows : 1. The average age of the subjects was 17.7 years, and the average score of BMI was 20.4. The average score of Rohrer and blood pressure were 119.1, 112.3/7.5mmHg, each. All of these were in a normal range. Daily calorie intake was 2676.8kcal and Na, K intakes were 152.76mEq, respectively. 2. 71.4% of subjects were susceptible to the disease associated with stress, although there was no significant difference among the salt level, stress and blood pressure. 3. There was significant difference between dietary Na intake ratio, urinary Na excretion and urinary K excretion rate (p<0.001). 4. There was significant difference between systolic blood pressure and BMI/Rohrer score(p<0.01).
