  • The purpose of this study was to investigate dietary behavior and nutritional knowledge related to sodium intake in high school students. A questionnaire survey was conducted in 400 high school students (200 boys) in Incheon, Korea. Survey data were analyzed according to gender and degree of obesity. The distribution of the degree of obesity was the highest in 231 normal weight individuals (57.8%), followed by 89 underweight (22.3%), 41 overweight (10.3%), and 39 obese (9.8%). The sodium-related undesirable dietary behavior score was 2.9 points out of 5 points. The detailed dietary behavior scores of 'I eat kimchi when I eat instant noodles or noodles' and 'I like dried fish with salt' were significantly higher in boys than in girls (p<0.05). It was found that boys consumed more frequently high sodium foods, such as pizza, hamburger, and hotdog than girls. According to the degree of obesity, the underweight group consumed more kimchi fried rice and potato chips frequently than the other groups (p<0.05). Preference for salty taste was not significantly different among the groups by gender and degree of obesity. Sodium-related nutritional knowledge score was 5.3 points out of 10 and which was significantly higher in girls or normal weight group than in boys or obesity group. These results suggest that nutritional education on sodium intake is needed because the nutritional knowledge of adolescents is relatively low. Moreover, intensive nutritional guidance is required, especially in boys or adolescents with undesirable degree of obesity.

  • The purpose of this study was to assess sodium and potassium intakes and urinary excretion of adults in Busan and to evaluate the relationship of urinary sodium/potassium excretion (UNa/UK) to the status of anthropometric, blood pressure, urine analysis, and nutrient intake of subjects. Nutrient intake by 24-h recall, 24-h UNa/UK were measured with 87 adults aged 20-59 yrs (42 men and 45 women). The mean intakes of sodium and potassium were 3915.4 mg and 3093.9 mg, respectively. The mean 24-h UNa/UK was 3457.0/1680.4 mg. UNa showed significant positive correlations with sodium intake (p < 0.001, p < 0.001), sodium/potassium ratio (p < 0.001, p < 0.01), UK (p < 0.001, p < 0.001), and UNa/UK ratio (p < 0.05, p < 0.01) in men and women and with age, BMI, systolic blood pressure (SBP) and diastolic blood pressure in women (p < 0.05, p < 0.05, p < 0.05, p < 0.05). The UK showed significant positive correlations sodium intake (p < 0.001, p < 0.001), UNa (p < 0.001, p < 0.001) in men and women and with sodium density in men (p < 0.001) and with age, intakes of protein and potassium in women (p < 0.01, p < 0.05, p < 0.05). Mean SBP was lowest in the second quartile and highest in the fourth quartile of UNa. Mean UNa in the second, third, and fourth quartiles were 2821.1 mg, 3621.3 mg, and 5456.4 mg, respectively. Mean SBP in the second, third, and fourth quartiles were 115.8 mmHg, 120.7 mmHg, and 125.9 mmHg, respectively. Based on the results, UNa was related to sodium intake, UK, and SBP. We conclude that nutritional education for the reduction of high sodium intake is needed in the general population to prevent and control adverse blood pressure levels.

  • Kimchi is a traditional fermented food of Korea and made by salting and fermenting vegetables. A negative impression on kimchi as a great source of sodium intake has grown in Korea since 1980 as people argue that sodium is a major cause of high blood pressure and metabolic syndrome. While people are more interested in healthy living in Korea, the negative impression is stronger now. This study analyzes the sensitive and negative reaction to sodium intake from kimchi, and suggests an alternative in the viewpoint that the sensitive reaction is one of food faddism which is a very popular topic currently in Korea.

  • In this study, we examined food intake, sodium intake, and satiety rate for different methods of consuming soup. Healthy young women (n=50) participated in this study. The subjects ate cooked rice and soup using a method that they preferred and then they were assigned into separate intake groups based on how they consumed their rice and soup. One group consisted of women that ate their soup and cooked rice separately (separate intake group, n=30). The second group consisted of the women who mixed the rice and the soup prior to consumption (mixed intake group, n=20). The mixed intake group consumed significantly more food (p<0.001) and sodium (p<0.05) than the separate intake group. Because of the high water content and ease of swallowing for the mixed intake method, the eating rate of the mixed intake group (42.5 g/min) was significantly higher than that of the separate intake group (28.8 g/min) (p<0.01). However, despite consuming 79.5 g more food at lunch, the rates of satiety were not significantly different before and after eating between the mixed intake and separate intake group. Therefore, eating rate, consumption norms and concept of "clean one's bowl" may influence food intake and sodium intake. Although more studies are needed, these data suggest eating cooked rice and soup separately may help to control obesity and hypertension.

  • BACKGROUND/OBJECTIVES: South Korean's sodium consumption level is more than twice the upper limit level suggested by the WHO. Steep increases in the prevalence of hypertension and cardiovascular disease in Korea necessitate more effective sodium reduction programs. This study was conducted in order to compare sodium intake-related eating behaviors and key psychosocial factors according to age group and gender. SUBJECTS/METHODS: Using an online survey, a total of 1,564 adults (20-59 years old) considered to be geographically representative of South Korea were recruited and surveyed. The major outcomes were perceived behaviors, knowledge, intentions, and self-efficacy related to sodium intake. RESULTS: The results show that perceived behavior and level of self-efficacy related to low sodium consumption differed by age and gender. Female participants showed better behavior and intention towards low sodium intake than male counterparts. Young participants in their 20s showed the lowest intention to change their current sodium intake as well as lowest self-efficacy measures. CONCLUSIONS: Future sodium reduction interventions should be developed with tailored messages targeting different age and gender groups. Specifically, interventions can be planned and implemented at the college level or for workers in their early career to increase their intention and self-efficacy as a means of preventing future health complications associated with high sodium intake.

  • Sodium is a necessary element for the body. Excessive intake of sodium is known as one of the risk factors for chronic diseases. Recently, increasing numbers of people in Korea are suffering from chronic diseases. Major causes of deaths were chronic degenerative disease with the rising aging population. Especially, the population of rural areas is growing older fast. In rural areas, it is known that under nutrition and high sodium intake were major nutritional problems. For sodium intake, there were some studies about contributing food items. They were not enough to show diets relate to sodium intakes. Thus, this study analyzed dishes contributing to sodium intakes of elderly living in rural areas. Dietary intakes using "the 24hour recall method" were used. For the analysis for sodium intakes, "Can-pro3.0" was used. Ranking of dishes by contributions of sodium intakes were Korean cabbage, kimchi (19.6%), seasoned soybean paste (5.3%), soybean paste (4.6%), soybean paste soup dried radish leaves (3.5%), hot pork and kimchi stew (3.4%) in order. Ranking of dish groups by sodium intakes was kimchies (28.3%), soup and hot soups (22.8%), stews and casseroles (9.7%), seasonings (8.2%),and seasoned vegetables (6.0%) in order. One-dish meals among cooked rice, wheat noodles among noodle and mandu, soups using the soybean paste, stews using soybean paste and kimchi, salted fish among grilled foods, stir-fried anchovy among stir-fried foods, seasoned spinach, and Korean cabbage kimchi contributed to sodium intakes. As the nutrition deficiency of the elderly living in rural areas could be a problem, and excessive sodium intakes is threatening to their health, it is needed for the senior citizens to have adequate knowledge for diets containing less sodium. And recipes for healthy food and nutrition education based on their diets are needed.

  • This study was conducted to investigate the degree of practice of dietary behavior and dining out in accordance with intake of sodium among male and female adults aged 20 years or older residing in the Seoul Metropolitan area or Chungcheong Province. A total of 530 copies of the questionnaire were distributed from May to July, 2014. The SH group who responded that they eat a lot of sodium constituted 30.6% (158 people), followed by the SM group who responded that their sodium intake is about average at 55.7% (288 people) and the SL group who answered that they do not eat much sodium at 13.7% (71 people). Those in the SL group showed positive results for dietary behavior patterns. The SL group showed the lowest rate in terms of how often they eat harmful foods, including processed foods, sweet foods, salty foods, or food with high animal fat content such as pork belly. Positive results among the SL group were prominent in terms of avoiding over-drinking, regular exercise, and nutritional knowledge, indicating greater health management. The distribution of each group in terms of self-perceived sodium intake showed significant differences across age, gender, and household income in terms of frequency of fast food intake, regularity of meals, purchase of foods with consideration of sodium amount, frequency of missed meals, balance of food intake, and health management habits.

  • Objective: To examine the effects of sodium intake on the correlations between the saltsensitive gene ${\alpha}$-adducin 1 (ADD1) and inflammatory cytokines in Korean childhood obesity. Methods: A total of 2,070 students aged 8-9 years old participated in this study. The anthropometrics, serum biochemistry profile, inflammatory cytokines, and three-day dietary assessment were analyzed according to sex, obesity degree, and ADD1 polymorphism. Results: The obesity prevalence was higher in boys (15.6%) than in girls (11.9%). Boys also showed higher values in anthropometrics; lipid, glucose, and insulin profiles; total calorie intakes, as well as those of sodium and calcium compared with those of the girls. The more obese were boys and girls, the higher were the anthropometrics and the blood levels (total cholesterol, triglyceride, low-density lipoprotein cholesterol, fasting blood sugar, and insulin), but the lower was high-density lipoprotein cholesterol. The obese boys had significantly higher sodium and Na/K intakes, while the obese girls had higher visfatin level and Na/K intake. In addition, an increase in the risk factors for blood pressure and obesity in ADD1 variants was identified. Serum tumor necrosis $factor-{\alpha}$($TNF-{\alpha}$) significantly increased with increasing sodium intake in the ADD1 W allele carriers, regardless of sex. The presence of obesity with the ADD1 W allele induced inflammatory accelerators such as $TNF-{\alpha}$ or C-reactive protein(CRP) with higher sodium intake. Conclusion: Obese children with an ADD1w allele can experience a more complex form of obesity than non-obese when exposed to an obesity-inducing environment and need to be controlled sodium intake in the diet.

  • It is well established that excessive sodium intake is related to a higher incidence of chronic diseases such as hypertension, stroke, coronary heart disease, cardiovascular disease and gastric cancer. Although the upper limit of the current sodium intake guideline by WHO is set at 2,000 mg/day for adults, sodium intake of Koreans is well over 4,700 mg/capita/day implying an urgent need to develop and implement sodium intake reduction policy at the national level. This study investigated the cost-effectiveness of the sodium intake reduction policy, for the first time, in Korea. Analyses were performed using most recent and representative data on national health insurance statistics, healthcare utilization, employment information, disease morbidity/mortality, etc. The socioeconomic benefits of the policy, resulting from reduced morbidity of those relevant diseases, included lower medical expenditures, transportation costs, caregiver cost for inpatients and income losses. The socioeconomic benefits from diminished mortality included reductions in earning losses and welfare losses caused by early deaths. It is estimated that the amount of total benefits of reducing sodium intake from 4.7 g to 3.0 g is 12.6 trillion Korean Won; and the size of its cost is 149 billion Won. Assuming that the effect of sodium intake reduction would become gradually evident over a 5-year period, the implied rate of average return to the sodium reduction policy is 7,790% for the following 25 years, suggesting a very high cost-effectiveness. Accordingly, development and implementation of a mid-to-long term plan for a consistent sodium intake reduction policy is extremely beneficial and well warranted.
