The purpose of this study was to investigate the salt-related dietary behaviors according to the stage of change model in middle school students from the Gyeongsangbuk-do area. Data were collected from, a total of 253 male and 210 female middle school students through. Self-reporting questionnaire. By stage of salt-related dietary behaviors, the 'Pre-contemplation stage' was comprised of 57.3%, the 'Contemplation stage' of 12.2%, the 'Preparation stage' of 7.4% and the 'Action stage' of 23.2% of students. There were significant differences in the stage of change according to the experience with salt-related nutrition education (p<0.05), wherein differences according to gender and parent's education were not observed. In the salt-related dietary behaviors, there were significant differences according to gender (p<0.05), pocket money (p<0.01), and the stage of change (p<0.001). Males had higher salt-related dietary behavior scores than females, while students who had more pocket money also had higher scores, and the action group had lower scores than the other groups. Among the 10 items of salt-related dietary behaviors, only 4 showed above the average score (2.92/5.00), including behaviors of liking kimchi, completely consuming snacks and instant foods, and drinking the broth of soups. The salt-related dietary score of males was higher than females, while the action group's score was lower than the other stages.

Purpose: In this study, we comparatively investigated the nutrition knowledge, dietary attitude, and dietary behavior related to salt according to the types of dietary life style for differences between the groups. Methods: The survey was conducted between May 1 to July 31, 2014 among 500 adults aged >19 years in Seoul, Gyeonggi-do and Chungcheong-do areas. Results: Factor analysis of the dietary life style, indicated 4 factors including food convenience factor, food information emphasis factor, behavior factor of pursing food taste, and food purchase standard factor, which were classified into 3 groups according to differentiated dietary life style types; group 1 emphasized convenience and diversity of food, and price sensitiveness. and included subjects who had low interest in health and nutrition and were less likely to take care of their health through regular exercise,; group 2 emphasized food ingredients, food additives, usage and food purchase standards. and included subjects who were more likely to take care of their health through exercise and showed lower intake of fast food and less cases of eating out.; and group 3 showed relatively higher tendency toward dietary life style factors than the other two groups. The level of nutrition knowledge in sodium intake differed according to dietary life styles, and showed a significant difference in the dietary practice of sodium intake. Conclusion: Nutrition education on the healthy dietary habit of reducing sodium intake be based on ge and gender. In addition, an effort is required to improve behavior, interest, and attitude according to the important tendencies of the dietary life style.

The purpose of this study was to evaluate salt-related dietary attitudes, behaviors, and nutrition knowledge according to urinary salt signal of university students. Based on urinary salt signal, we classified subjects into an "adequate Na intake (ANI)" group (n=52) (salt ${\leq}6g$) and "excess Na intake (ENI)" group (n=66) (salt >6 g). Subjects were asked about general characteristics, lifestyle, salt-related dietary attitudes, behaviors, and nutritional knowledge using questionnaire. The ENI group had more subjects who were drinkers (P<0.05) compared to the ANI group. The ENI group (33.45) showed a significantly lower score in terms of salt-related dietary attitudes compared to the ANI group (35.50) (P<0.05). There was no significant difference in the total score of salt-related dietary behavior between the groups. The score of nutrition knowledge was significantly higher in the ANI (9.77) group than in the ENI (8.82) group (P<0.05). The correlation analysis indicated that the urinary salt signal had a negative correlation with the salt-related dietary attitude score after adjustments for age, sex, and body mass index (r=-0.2100, P<0.05). These results support the validity of using the urinary salt signal to simplify estimation of sodium intake.

Objectives: The purpose of this study was to compare and analyze the results of salty taste assessment, dietary attitudes, and dietary behaviors among adult and senior women by region and by age. The results generated from this was expected to provide fundamental data for implementing a nationwide salt reduction education program. Methods: The salty taste assessment tool was applied to 4,064 subjects from 15 areas in Korea. Also, a survey of dietary attitude and dietary behavior related to salt intake was conducted for all subjects participated in this study. Results: The salty taste assessment scores by region and by age were the lowest in capital (p < 0.01) and was highest among the 70+ year age group (p < 0.01). The dietary attitude scores and dietary behavior scores showed that Gyeongsang was the highest (p < 0.001) and the capital was the lowest. The dietary attitude scores were highest at 20&30's followed by 40's and 70's group (p < 0.001). Dietary behavior scores showed that 20's~30's and 40's groups were higher than the other age groups (p < 0.001). The score of 'I like kimchi' was $3.46{\pm}0.88$, which was the highest among 10 dietary behavior questions. The score of 'I eat a lot of kimchi' was $3.30{\pm}0.90$, which was the highest among 10 dietary behavior questions related to salt intake. The scores of salty taste assessment had significant positive correlations between the scores of dietary attitude (p < 0.001), dietary behavior (p < 0.001) and self-awareness (p < 0.001). Conclusions: Based on the results of salty taste assessment, we observed a tendency that older people and regions except the capital had higher preference for salty taste. Our results suggested the necessity for a nationwide salty reduction education program tailored for regions and for different age groups.

This study was designed to investigate dietary life related to sodium of participants in hypertension and diabetes preventive education at the public health center located in Incheon Metropolitan City. Subjects were comprised of 301 adults (males: 102, female: 199) of age 50 years and above. The questionnaire for dietary life and salty taste assessment were performed on the subjects. Data were analyzed using SPSS package (ver. 18.0). According to the result of questionnaire for dietary behavior, 70% of the subjects were in the low salt intake group (p<0.001). In the result of questionnaire for dietary frequency, all ages groups were in the low salt intake group (p<0.01). The data of questionnaire for dietary behavior showed that the subjects of age above 75 years preferred salted seafood, soup, and kimchi (p<0.01). The data of questionnaire for dietary frequency showed that the subjects of age between 65 and 74, least chose fried kimchi, noodle, and soybean paste soup with clams (p<0.05), and the healthy adult groups chose kimchi stew, ssam and ssamjang (p<0.05). The score for dietary behavior in male subjects was higher than female subjects (p<0.01). In particular, the score for dietary frequency was the lowest in the subjects of age between 65 and 74 (p<0.01). The mean value of salty taste assessment in the subjects was 0.41% which is higher than the ideal value of 0.3% (p<0.01). Offering more nutrition education and continuous feedback of healthcare center may be needed to improve the health status of the adults.

This study was performed for the purpose of establishing proper dietary behaviors and improving sodium intake status by investigating nutrition knowledge, dietary behaviors, and food intake frequency related to sodium in 398 university students living in Gyeonggi-do and Incheon. Female students showed a higher rate of eating out more than five times a week as well as daily snack intake than male students. Female students showed a higher score for sodium-related nutrition knowledge than male students, whereas male students showed higher sodium intake than female students. Subjects who showed a higher frequency of eating out and snack intake also showed a higher salt intake ratio and sodium-related nutrition knowledge. Subjects with higher scores related to sodium-related nutrition knowledge showed a higher low salt intake ratio and incidence of low sodium food intake. From this research, depending on the level of nutrition knowledge related to sodium university students showed differences in dietary behavior related to sodium intake. This result would be helpful to develop lower sodium training materials specific to low sodium food selection tips, reading nutrition labels, and so on.

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.
