This study was done to explore the effect of Korean women's salt usage behavior on their sodium intake and excretion according to aging. Dietary sodium intake and salt usage behavior were analyzed to compare the difference between young and middle-aged women. One hundred fifty six young women and 77 middle-aged women without hypertension or any current medication were recruited. Body mass index, waist hip ratio, blood pressure were measured from each subject. Salt usage behaviors were surveyed with questionnaire, sodium intake with 24-hr recall method, and sodium excretion with spot urine. Middle-aged women were more obese than young women according to body mass index and waist hip ratio. Blood pressure was significantly higher for the middle-aged. Young women consumed more fats and middle-aged women more carbohydrates. Middle-aged women consumed more sodium and potassium, and excreted more sodium. Among questionnaire items, kimchi, soup or pot stew, or salted vegetables were found to be related with high sodium diet. Salted vegetables and salted nuts and potato chips were significantly correlated with young women's high sodium diet, while soy sauce on fried food, kimchi, salted vegetables accounted for middle-aged women's high sodium diet. With these results, we concluded that middle-aged women consumed more carbohydrates, less fat, and more sodium and potassium than young women. Middle-aged women frequently choose kimchi, soup or pot stew, or salted vegetables, and they contribute to high sodium intake. We recommend to choose low-salt kimchi, less soup or pot stew, and more fresh vegetables for lower sodium diet.
本研究旨在探讨韩国女性的盐使用行为随年龄变化对钠摄入和排泄的影响。分析膳食钠摄入和盐使用行为，以比较年轻和中年女性之间的差异。共招募了 156 名年轻女性和 77 名无高血压或正在服用任何药物的中年女性。从每位受试者中测量体重指数、腰臀比、血压。通过问卷调查了解盐使用行为，通过 24 小时回忆法了解钠摄入量，通过随机尿样了解钠排泄量。中年女性的体重指数和腰臀比均高于年轻女性，且血压明显更高。年轻女性摄入更多的脂肪，中年女性摄入更多的碳水化合物。中年女性摄入更多的钠和钾，排泄更多的钠。在问卷调查项目中，发现泡菜、汤或炖菜或咸菜与高钠饮食有关。咸菜和咸坚果、薯片与年轻女性的高钠饮食显著相关，而油炸食品上的酱油、泡菜、咸菜则与中年女性的高钠饮食有关。根据这些结果，我们得出结论，中年女性比年轻女性摄入更多的碳水化合物、更少的脂肪和更多的钠和钾。中年女性经常选择泡菜、汤或炖菜或咸菜，这导致了高钠摄入。我们建议选择低盐泡菜、少喝汤或炖菜、多吃新鲜蔬菜，以减少钠的摄入。
