The purpose of this study was to compare regional differences in salty taste assessments, nutrition knowledge, dietary attitudes and dietary behaviors associated with high-salt diets in four national regions in Korea (Region 1: Seoul, Sokcho, Region 2: Buyeo, Jecheon, Gong Ju, Region 3: Daegu, Gyeongsan, Region 4: Jeon Ju). Subjects were 860 persons who participated in sodium reduction campaign. The result of the salty taste assessment by region was not significantly different. The nutrition knowledge score of subjects in Region 1 was the highest. Dietary attitude scores that showed preference for high-salt diets of Region 2 and Region 4 subjects were higher than those of Regions 1 and 3 subjects (p < 0.001). Dietary behavior scores were not significantly different among regions. The correlation between sodium intake and salty taste assessment was significant (p < 0.01). Older subjects who had high blood pressure levels and lower nutrition knowledge were more likely to have high sodium intakes. Even though the salty taste assessment and dietary behavior scores by region were not significantly different, the salty taste assessment scores had a significant negative correlation with nutrition knowledge and had a significant positive correlation with dietary attitude and dietary behavior in terms of preference for high-salt diets. Therefore, nationwide education regarding salt intake reduction and health and a campaign to encourage favorable attitudes and behavioral changes regarding consumption of a no-salt / low-salt diet is needed.

Objectives: The purpose of this study was to analyze correlation thresholds and assessment for salty taste and high-salt dietary behaviors by age. Methods: A total of 524 subjects including 100 each of elementary school students, middle school students, college students, and elderly as well as 124 adults were surveyed for detection and recognition thresholds, salty taste assessments, and high-salt dietary behaviors. Results: Elementary students had a lower detection threshold (p<0.05) and recognition threshold (p<0.01) than did the other groups. Salty taste assessments were lowest among elementary students, followed by middle school students, while college students, adults, and elderly had higher assessment score (p<0.001). Elementary students had significantly lower scores for high-salt dietary behavior than did middle school students, college students, adults and elderly (p<0.001). Middle school students had higher scores for high-salt dietary behavior than did elementary school students and elderly (p<0.001) but no meaningful difference was found in dietary behavior scores between college students, adults, and elderly. There were positive correlations between high-salt dietary behavior and detection thresholds (p<0.001), recognition thresholds (p<0.001), and salty taste assessment (p<0.001). High-salt dietary behavior was more positively correlated with salty taste assessment than detection and recognition thresholds for salty taste. Conclusions: This study suggested that salty taste assessments were positively associated with scores for the detection and recognition thresholds and high-salt dietary behavior.

The purpose of this study was to compare and analyze the assessment of salty taste and high-salt dietary behaviors of Korean university students and their Chinese counterparts. The researchers developed a taste assessment computer program focusing on preference for salty taste, and it was applied to 300 university students, including 100 Korean students, and 100 Chinese students in Daegu of South Korea, and 100 Chinese students in Shenyang of China (144 males and 156 females). The results of the taste assessment of Chinese and Korean university students are as follows. Among males, Koreans (36.0%), Chinese students in Korea (36.2%), and Chinese (40.4%) scored highest in the "a bit salty" followed by "normal." Among females, Koreans (36.0%), Chinese students in Korea (49.1%), and Chinese (28.3%) scored highest in the "normal". In terms of salt concentration in solution, among the male subjects, most Koreans favored the salt concentration of 0.31%, which is considered to be a "normal" concentration; most Chinese students in Korea favored 0.63%, which is considered to be "a bit salty", and most Chinese favored the concentration of 1.25%, which is considered to be "salty". As for the female subjects, Koreans, Chinese students studying abroad, and Chinese favored 0.31%, the "normal" level of concentration. Korean students scored higher than Chinese students in Korea and Chinese students both in males and females (p < 0.001, p < 0.01), in terms of high-salt dietary behaviors favored salty taste. This study suggests that Chinese university students need nutrition education in terms of modifying eating behaviors to reduce dietary salt intake.

Objectives: Increasing salt preferences with age are said to increase preferences of salty foods, thereby leading to greater sodium consumption, which has further implication for hypertension. This study examined the link between preference of salty taste and dietary factors and health-related risk factors in Korean elderly people. Methods: We studied 312 elderly individuals aged > 65 years (male, 100 and female, 212). With each subject, pleasant concentration of NaCl was estimated using the sip-and-spit method. Dietary habits, food preferences, consumption frequencies, anthropometric and biochemical assessment were assessed. Results: The pleasant salt concentration was significantly increased in individuals older than 75 years (p < 0.05). Subjects who liked high concentration of salt showed significantly higher preferences for salty foods (p < 0.001). Results showed significant effects (p < 0.01) of fruit & fruit juice consumption frequencies, MNA (mini-nutritional assessment), cognition score, BMI, body fat %, waist circumference, arm circumference, calf circumference, vitamin D level that subjects who likes low salty taste were higher than subjects who likes high salty taste. Conclusions: The preference for salty taste in the elderly was not correlated with hypertension. But, increased preference for salty taste with age and increased salty food preferences may result in higher sodium consumption. Therefore, nutritional education regarding lowering salt preference and favorable behaviors of low-salt diet is needed to improve the quality of life in the rural elderly.

The purpose of this study was to evaluate the sodium-related dietary attitudes, behaviors, and nutritional knowledge in university students according to the practice of dietary guidelines for Koreans established by the Ministry of Health and Welfare, Republic of Korea. Based on the total practice score related to the dietary guidelines (PDG), we classified subjects into a "low practice of the dietary guidelines (LPDG)" group (n=94, male=43, female=51) (total score of PDG ${\leq}13$) and a "high practice of the dietary guidelines (HPDG)" group (n=56, male=32, female=24) (total score of PDG >13). Subjects were asked about general characteristics, lifestyle, salt-related dietary attitudes, behaviors, and nutritional knowledge using a questionnaire. The LPDG group had more subjects who were breakfast skippers (p<0.001) compared to the HPDG group. The LPDG group (31.26) had a significantly lower score in terms of salt-related dietary attitudes compared to the HPDG group (33.77) (p=0.0042). The score for salt-related dietary attitudes was significantly higher in the HPDG (32.52) group than in the LPDG (29.91) group (p=0.0041). There was no significant difference in the total score for salt-related nutrition knowledge between the groups. The correlation analysis indicated that the dietary guidelines practice score had a positive correlation with the salt-related dietary attitude score (r=0.3593, p<0.0001) and the dietary attitude score (r=0.3443, p<0.0001) after adjustments for sex. These results show that the degree of adherence to the dietary guidelines for adults may be related to sodium-related dietary attitudes, behaviors, and nutrition knowledge.

This study was to investigate the changes in dietary practices, reasons for making dietary changes, current food consumption patterns, and eating habits. Data were collected from 515 parents whose children were attending an elementary school and a middle school in Kimcheon. Among the twenty food groups studied, subjects reported eating more fruit, vegetables, lower-fat meats, high-fat meats, reduced/skim milk, and eggs and less sugar, fats, rice, salt, potato/sweet potato, and chicken. The changes in dietary practices except high-fat meats and salt were significantly different between sex, age, education level, income level, or BMI groups. The primary reason for making dietary changes was 'concerned about family's health'. The average rate of never eating breakfast or less than 2 times per week was found to be 23.2% with a greater rate in younger age group. The rate of breakfast skipping was found to vary between different age and education groups. The regularity of mealtime and overeating practices were significantly different between age groups. Eating out practices were found to vary between different age, education, and income groups. People at younger age group in Kimcheon should be targeted for nutrition education about eating habits. These findings are applicable at the planning and implementation stages of various nutritional improvement projects.

The purpose of this study was to investigate dietary behaviors and health-related lifestyles of adult visitors at a public health center in Gyeonggi urban area. A survey using questionnaire was conducted with 949 visitors at Seongnam public health centers from June to August, 2012. The data from 905 respondents were analyzed by gender, consisting of 322 males and 583 females, and age group, consisting of 243 low-age group (LA), 312 middle-age group (MA), 350 high-age group (HA), aged 20 to 30 years, 31 to 50 years, and 51 to 69 years, respectively. Average Body Mass Index was 23.0, which increased with age, and education level was high in LA. 59.0 percent of the subjects had various diseases, and the incidence of hypertension was the highest, followed by allergy, hyperlipidemia, diabetes mellitus, joint rheumatism. Incidence rates of chronic disease increased with age, which were lower than those from 2011 Korea National Health and Nutrition Examination Survey (KNHANES). Weekly drinking frequency rate and smoking rate decreased with age, and exercise performing rate was high at male and HA, which showed the same tendency as KNHANES. Female and HA showed more healthy dietary behaviors such as restricting salt, sugar, oily foods, foods containing food additives, calorie, caring for balanced diet, and referring to nutrition label. Subjects chose stress as the first factor, followed by diet, exercise, etc., among 13 suggested factors which strongly influence on human's life-span. In general, public health center visitors, especially female and HA, showed better dietary behaviors and health-related lifestyles compared with KNHANES.

Hypertension is among the most common and important risk factors for stroke, heart attack, and heart failure which is considered to be the leading cause of death in Korea. The prevalence rate of hypertension in Korea is 27.9%, according to the 2006 Korea National Health and Nutrition Survey. Since non-pharmacologic nutrition education is recommended as the first step in the management of hypertension, evaluation of nutrition program is needed to form strategies for improving patients' dietary adherence. This study was designed to evaluate the overall effectiveness of a hypertension nutrition education program (HNEP) for reducing the salt intake, at a public health center located in Gyunggi-province. The HNEP was offered for 16 weeks from May to September in 2007. Nutrition education activities included cooking classes, food preparation demonstrations, physical fitness programs, salty taste preference test sessions, games, case-study presentations, planning and evaluation of menus, etc. Forty patients participated fully in the program which had 47 female enrollees. Data about nutrient intake (24-hour recall), nutrition knowledge, food behavior were collected before (baseline) and after the program. Changes after program completion indicated the following: 1) diastolic blood pressure was decreased (p < 0.05), 2) sodium (salt) intake was also decreased (p < 0.01), especially baseline high salt intake group, 3) nutrition knowledge was improved (p<0.001), 4) dietary behaviors for maintaining a low salt diet was improved (p < 0.001), 5) participants preferred cooking class from nutrition education methods. As a conclusion, it appears that a nutrition education program for hypertensive female elderly for reducing the salt intake might effectively decrease blood pressure and salt intake. It also improves nutrition knowledge, dietary behavior, and finally adherence to a recommendable low-sodium diet.

This study was performed to understand recognition and behaviors related to sodium intake of Korean adults. The data were collected from subjects including 267 male and 285 female adults in nationwide and compared by gender and by age. We found that the male group showed significantly higher smoking, alcohol drinking, and exercise does the female group. The older group (40 to 59 years) revealed significantly higher exercise and lower alcohol drinking; however general disease and hypertension prevalence, diet therapy practice, and meditation for hypertension were higher. Recognizing sodium levels of foods containing high-sodium, and sodium-nutriture labels when purchasing foods, and knowing differences between salt and sodium of the male group or recognizing sodium levels of foods containing high-sodium of the older group was worse than the other. Among the 32 food behaviors, only 12 were identified as significantly correlated to sodium intake levels including behaviors of preferring Chinese and Japanese foods to Western foods, preferring kimchi to raw vegetables, completely consuming soup, stew, noodle liquid, liking of dried fish and salted mackerel, frequent eat-outs or delivered foods, and so forth. There were significant differences between gender or age groups in terms of sodium intake-increasing behaviors; the male group showed higher behaviors of preferring salty taste and eating all broths. And the older group revealed higher behavior of adding table salt as well as the previous two, however, the younger group showed more behaviors of eat-outs or delivered foods and not the liquid of kimchi.
