Abstract

This study compares salt-related dietary patterns according to sodium intake. A survey was conducted with 257 college students(130 male and 127 female students) in the Busan area. Dish Frequency Questionnaire 70(DFQ 70) was used to quantitatively estimate sodium intake. A short dish frequency questionnaire(DFQ 15) was used to screen subjects with high or low- salt intake. The sodium intake of male students based on DFQ 70 was significantly higher than that of female students(p<0.05). Sodium intake has significant negative effects on systolic and diastolic blood pressure(p<0.05). In the high-salt intake(HS) group, classified by DFQ 15, the number of male students was significantly higher than that of female students(p<0.01). The systolic blood pressure of the HS group was significantly higher than that of the low-salt intake(LS) group(p<0.05). Salt-related dietary behavior score and eating habit score for the HS group were significantly higher than those for the LS group(p<0.01). The sodium intake of the HS group based on DFQ 70 was significantly higher than that of the LS group(p<0.01). In these results, college students in Busan area showed high blood pressure and high sodium intake compared to Korean DRIs. The results indicate a need for various education programs to help college students practice a low-sodium diet.
