This study was performed to observe the levels of serum and dietary Ca and P, and blood pressure in rural university male students(smoker : 35 persons, non smoker : 32 persons), Three-day dietary record and blood samples were collected for measurements of the Ca and P levels of dietary intake and serum. The results were as follows: 1) There were no significant differences between smokers and non-smokers in terms of height, weight, and BMI. 2) Mean blood pressures on smokers and non-smokers were 131.33/93.75mmHg, 119.37/80.62mmHg, respectively. Blood pressure of smokers was higher than that of non-smokers (p＜0.05). 3) There were no significant difference between smokers and non-smokers in calcium, phosphorus, and Ca/P ratio of dietary intake and serum. The results of this study suggest that non-smoking education programs for smokers including the information on the desirable food habits for prevention of hypertension should be developed.
