In this study, we investigated protection motivation and behavioral intention to prevent serious illnesses related to excessive sodium intake among the university students in Gyeongnam and Busan. Within the protection motivation theory (PMT) framework, a survey questionnaire was developed to measure participants' perceptions on the severity of and the vulnerability to the threat of serious diseases due to the high sodium intake as well as the effectiveness of preventive measures (response efficacy), and the ability to perform them (self-efficacy) along with their willingness to follow recommendations (behavioral intention). Data was collected in June 2015. Study participants were divided into either low (n=117) or high (n=177) sodium intake behavior groups based on their current behaviors. Exploratory factor analysis was performed to measure construct validity and Cronbach's alpha was calculated to check reliability of measurement items. The high sodium intake behavior group perceived higher vulnerability than the low sodium intake behavior group among four PMT factors. Differences of the other three factors were not significant between the two groups. The results of hierarchical regression analysis indicated that self-efficacy and response efficacy affected behavioral intention of high sodium intake behavior among students. Hence, development of strategies to increase self-efficacy and response efficacy are strongly recommended.

Purpose: This study aimed to examine the compliance to a low-salt diet, sodium intake, and preferred salty taste in elderly patients with hypertension. Methods: A cross-sectional descriptive design was used. Participants were 105 elderly patients with hypertension living in a rural area. The compliance with a low-salt diet, sodium intake, and preferred salty taste, blood pressure, body mass index, and waist circumference were measured, and compared according to the general characteristics and the levels of blood pressure. Descriptive statistics, $X^2$-test, t-test, and ANOVA were used for data analysis. Results: compliance with a low-salt diet was marginally elevated. Sodium intake was relatively high and the main sources were seasonings and vegetables. The participants tended to prefer high levels of salt. Sodium intake was significantly higher the hypertensive individuals (stage I and II) compared to prehypertensive subjects on a normal maintenance diet. Sodium intake from vegetables was also significantly different between the two groups. Conclusion: Nursing intervention for hypertensive elderly patients should include strategies to decrease sodium intake.

With globalization taking place at a rapid speed, more and more people move from one place to another and more people with diverse cultural backgrounds are now living together than ever before. As a result, more people go through the process of acculturation. Dietary acculturation, a part of overall acculturation, is a series of changes that occur in food and nutrient consumption and dietary behaviors. This paper examined dietary acculturation in Korean Americans through a critical literature review. The current diet quality of Korean Americans is fair, and the areas in need of improvement include sodium, calcium, and fiber intakes. Korean Americans had different diet profiles by acculturation status； however, whether dietary acculturation leads to a lower diet quality is not conclusive at this time. This paper also suggests areas that warrant consideration in future research： 1) acculturation measures, 2) dietary measures, 3) possible factors affecting dietary acculturation, 4) health consequences of dietary acculturation, and 5) study design issues. Studying dietary acculturation among immigrants and their offspring is important because it will provide useful insights for designing health and nutrition interventions in both original and new countries. Quality research in dietary acculturation requires collaborations among researchers from different nations because it deals with diverse cultures.

The aim of this study is to elevate the efficiency of salting with low salt concentration in order to improve the quality of salted Chinese cabbage. The efficiency of salting was tested with various sub-atmosphere(760mmHg to 0mmHg), temperature(20$^{\circ}C$ and 30$^{\circ}C$), and concentration of salt(3%, 5% and 10%). The salting efficiency was estimated by amounts of juice, calcium elution, sodium penetration and the state of tissue. The amunts of juice eleuted from Chinese cabbage was increased significantly with the decrease of atmosphere and the time to reach the highest amounts was reduced. This tendency was promoted, with increase of salinigy(from 3% to 10%)and the increase of temperature(more juice at 30$^{\circ}C$ than 20$^{\circ}C$). The amounts of eluted calcium from Chinese cabbage tissue during salting under sub-atmosphere was directly proportional to amounts of juice and was inversely proportional to penetrated sodium. The salting time was reduced with elevation of sub-atmosphere. It was desirable to take between 5.5 and 9 hours to salt under the condition of 3% of salting, 20$^{\circ}C$, and 560-0mmHg. It took between 4.4 and 5 hours under 5% of salt and between 4 and 4.5 hours under 10% of salt. However, it was undesirable because the drying phenomenon and the transparency of tissue appeared under 30$^{\circ}C$ and 160-0mmHg.

This study assessed yearly trends of food and nutrient intake among high school students aged 16 to 18 years (n=2,377) using the 2007~2015 Korea National Health and Nutrition Examination Survey (KNHANES). Yearly trends of food or nutrient intake were analyzed via logistic regression analysis. The results showed that consumption of sugars & sweets, and beverages & alcohols was increased rapidly during this period (p<0.0001). Intake of meat & meat products, and fish & shellfish also was increased (p=0.0008). Intake of grains and grain products was increased until year 2011 but declined after 2012 (p=0.0025). Consumption of vegetables, and milk & milk products was decreased (p=0.0395). Intake of protein, fat, thiamin, riboflavin, niacin, and iron was increased (p=0.0445). Carbohydrate energy ratio was decreased, whereas fat energy ratio was increased (p=0.0235). Most nutrient intakes satisfied the dietary reference intakes for Koreans except dietary fiber (19.6~26.2%), calcium (46.9~55.2%) and sodium (more than 221.4%) during this period. There was a significant positive correlation between most food group intakes and most nutrient intakes (p=0.0468). Therefore, it is crucial to increase dietary fiber and calcium intake and decrease consumption of sugars, fats and sodium through diverse eating of food groups to ensure balanced nutrition of subjects.

Purpose: The aim of this study was to investigate the dietary quality of food consumed away from home among Korean children and adolescents. Methods: Data were obtained from the 2010~2012 KNHANES (Korea National Health and Nutrition Examination Survey) and included 3,583 subjects aged 7 to 18 years old. The frequency of food consumed away from home was dichotomized into more than once or less than once per day. Results: Thirty percent of subjects were shown to consume food away from home more than once per day, and older children from higher income households showed a higher frequency of food consumed away from home compared to other children. The percentage of children and adolescents cited as regularly skipping breakfast was 19%. Individuals who ate out more than once per day showed higher consumption of energy and sodium than those who ate out less than once per day. Conclusion: Excessive intakes of energy and sodium are associated with obesity, high blood pressure, diabetes, and obesity-related diseases. Thus, there is a need for nutritional intervention and educational efforts to improve child nutrition and prevent obesity.

This study was peformed to assess the nutritional status of female nursing home residents by dietary intake. The subjects were 60 nursing home residents aged over 60 from 3 different nursing homes in Seoul, Cheonan and Chunchon. Dietary intake was assessed by 24-hr recall and nutrient intake was calculated using CAN-Pro and database for vitamin E established by authors. To establish vitamin E database, we analyzed vitamin E concentration using HPLC in several foods consumed frequently by nursing home residents. The results of nutrient intake were as follows; 1) Average daily intakes of energy, protein, phosphorous, iron, vitamin $B_1$ and niacin were higher than RDA, but calcium, vitamin $B_2$ and niacin of Chunchon were lower than RDA. 2) Intakes of protein, sodium and niacin of Cheonan residents were significantly higher than those of Seoul. 3) Intakes of phosphorous, potassium, vitamin $B_1$ and dietary fiber of Cheonan residents were significantly higher than Seoul and Chunchon. 4) Intakes of sodium and cholesterol of Seoul residents were higher than Cheonan and Chunchon. 5) Average daily intake of vitamin E was lower than RDA. Especially vitamin A intake of Cheonan residents was significantly lower than other two cities.

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.

This study was intended to investigate the sodium-related perception, dietary behavior, and practicability of methods for reducing sodium intake(RSI) according to the stage of change in consumers. The survey was conducted to 770 housewives, among them 553 subjects who answered the key questions for the stage of change were categorized into 'Maintenance (M)' stage (maintaining reduced salt intake for more than 6 months; n = 287, 51.90%), 'Action (A)' stage (maintaining reduced salt intake for less than 6 months; n=139, 25.14%), and 'Pre-Action (P)' stage (not starting reduced salt intake; n = 127, 22.97%). The subjects in M and A were significantly older than those in P (p < 0.01). The scores of desirable dietary habit and dietary balance were the highest in M followed by A and P. When eating out, the subjects in P considered 'price' more and 'healthiness of food' less than those in M and A did. Among the guidelines for RSI, 'Avoid Processed Foods', 'Eat enough vegetables and fruits' and 'Add little amount of dipping sauce for fried food' were selected as the three easiest items to perform. With regard to the sodium-related perception, the subjects in M considered eating-out food to be more salty than homemade dishes, read nutrition labels more, avoided table salt or dipping sauce for fried food more, and had 'own low-sodium recipe' than those in P (p < 0.001). It is suggested that practicability of actions for RSI and the stage of change should be considered to develop effective personalized education program and nutrition guidance.
