Objectives: This study was conducted to measure the intake rate of SSBs (sugar sweetened beverages) and examine the relationship between health behavior factors and SSBs intake by adolescents. Methods: This study used data from the 2016 Korea Youth Risk Behavior Web-based Survey, which included 65,528 study participants. SSBs intake frequency was measured by asking respondents if they consumed soda, high-caffeinated beverages, and sugary drinks during the previous week. Type of intake was categorized into three groups according to the number of consumed drinks [SSBs (0): None; SSBs (1-2): 1 or 2 consumed; SSBs (3): 3 consumed]. Multinomial logistic regression analysis was used to examine health behaviors that affected SSBs consumption. Results: Increased SSBs intake was significantly correlated with current smoking (OR=2.4, 95% CI=1.82-3.17), current drinking (OR=2.13, 95% CI=1.82-2.51), sedentary time increase (OR=1.31, 95% CI=1.15-1.49), three days or more physical activity per week (OR=1.12, 95% CI=1.02-1.24), <8 hours sleep (OR=1.6, 95% CI=1.43-1.78), increased internet usage time (OR=1.44, 95% CI=1.25-1.65). Conclusions: Sugar-sweetened beverages intake by Korean adolescents was associated with health behaviors such as smoking, drinking, sedentary time increase, more physical activity, poor sleeping time, and increased internet use time. Based on these results, it is necessary to recognize the influence of SSBs intake and to intervene to reduce consumption of SSBs.

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.

Although excessive intake of sodium is known to cause various diseases and threaten public health and policies for reducing overconsumption of sodium are being implemented, the theoretical research on sodium intake is incomplete. This study attempted to provide a policy basis by examining whether or not planned behavior theory, which is a typical health communication theory used to describe health-related behaviors, can be applied to explain sodium intake behavior. Especially, sodium ingestion behaviors were compared using the theory of actions planned for men and women as well as young people, middle-aged, and elderly persons, who are predicted to show differences in eating habits. In this study, questionnaires were prepared to measure the daily eating habits of subjects and subordinate factors of planned behavior theory: behavioral beliefs, outcome expectations, normative beliefs, compliance motivation, and control beliefs. Questionnaires were given to 93 college students and their families. As a result of the difference analysis and path analysis of the questionnaire responses, the following suggestions were obtained. First, age difference is more obvious than sex difference in terms of low salt intentions. For example, older people are healthier than younger people in terms of eating habits and health concerns. Second, the elderly are more likely to practice the low-salt formula when they are provided information on the benefits and effects of the low-salt formula compared to younger ones. Third, systematic efforts are needed to promote a culture that emphasizes the health benefits of a low salt diet rather than providing piecemeal information on the advantages and effects of a low salt diet.

This study was conducted to assess improvements in nutritional status following the application of nutrition education to elderly patients in a long-term care hospital. The study was carried out from January to May 2009, during which a preliminary survey, a pretest, the application of nutrition education, and a post-test were applied in stages. The number of subjects at pretest was 81, and the number of participants included in the final analysis was 61 (18 men, 43 women), all of whom participated in both the nutrition education program and the post-test. The survey consisted of general demographic items, health behaviors, dietary behaviors, the Nutrition Screening Initiative checklist, and nutrient intake assessment (24 hour recall method). The nutrition education program lasted for four weeks. It included a basic education program, provided once a week, and mini-education program, which was offered daily during lunch times. The survey was conducted before and after the education program using the same assessment method, although some items were included only at pretest. When analyzing the changes in elderly patients after the nutritional education program, we found that, among subjective dietary behaviors, self-rated perceptions of health (P<0.001) and of depression (P<0.001) improved significantly and that dietary behavior scores also improved significantly (P<0.001), while nutritional risk levels decreased. In terms of nutrient intake, subjects' intake of energy, protein, fat, carbohydrate, calcium, phosphorus, iron, vitamin A, thiamin, riboflavin, niacin, and vitamin C all increased significantly (P<0.001). These results indicated that nutritional education is effective in improving the nutritional status of elderly patients. We hope that the results of this study can be used as preliminary data for establishing guidelines for nutrition management tailored to elderly patients in long-term care hospitals.

This study was conducted to search the health food intake behavioral intentions of male workers. The health-related behavior of 150 subjects were compared(smoke, alcohol drink, breakfast, BMI, sleep, exercise and health check). On the basis of the Theory of Planned Behavior, the factors health-food intake behavior were evaluated; there were normative beliefs, motivation for compliance, subjective norms, social influence factors, and barriers as perceived behavior control. The results were showed with five points by the Likert scale and Significance by t-test. The most frequently consumed health food was tea(3.40/4points) followed by healthy drinks(2.49/4). As behavioral beliefs, if consumption of 'nutritional supplements'(3.61/5) and 'fatigue recovery'(3.62/5) received the highest scores. As a result, the idea of 'nutritional supplements'(3.94/5) and 'fatigue recovery'(4.06/5) were the important aspects, but others were also positively evaluated. As a sub-factor of subjective norms on normative beliefs, The highest social groups to encourage consumption of health food were parents (3.93/5), and the lowest were doctors (3.02/5). The most influential people were doctors (3.67/5) and spouses (3.65/5). Barriers to consumption health food were side effects (1.09/5) and price (2.08/5). Taking Ginseng products and other processed foods (juice, honey, bamboo, etc.) were correlated with health concern (p<0.05). Taking traditional stamina foods was correlated with dietary habit recognition (p<0.05). Mineral intake was positively correlated with age. Healthy drinks was negative (p<0.05). Minerals and supplement consumption were correlated with the practice of healthy behavior (p<0.01).

The purpose of this study was to compare nutrients intake, eating behavior, and health indices according to intake frequency of wheat-based foods, using results from the 2013~2015 National Health and Nutrition Examination Survey. Subjects were 882 men age 40~64. According to intake frequency of wheat-based foods per week, two groups (Low intake group (LG); less than four times, High intake group (HG); more than four times) were divided, and their percentages were 54.0% and 46.0% respectively. Frequency of consuming wheat-based foods per week was 4.80, and there was significant difference (p<0.001) in both groups. Intake frequency according to wheat-based foods was high in noodles, cookies, and breads. Daily energy intake was higher, approximately 630 kcal in HG than LG (p<0.001). Also, energy ratio of fat and protein was higher in HG. There were significant differences in nutrient density per 1,000 kcal of minerals and vitamins between the two groups (p<0.01, p<0.001), except calcium, phosphorus, and niacin. In dietary behavior, frequency of meals (daily) was significant. In total cholesterol and LDL-cholesterol of health indices, HG was higher than LG (p<0.01). Results of this study reveal that frequent intake of wheat-based foods has negative effect on nutrition and health.

Especially, the teenage period, an important lifetime to develop both physically and mentally, needs to be helpful to promote the growth of the body and to keep a well-balanced mind through a balanced and nourishing diet. It is well known that the western style fast food is the most liked meal by teenagers. Wrong recognition about fast food and its frequent intake by adolescents can lead to unbalanced diet and food behaviors which may also connect with a poor impact on their personalities as well as their physical health. In this study, therefore, relationships between fast food intake frequency and food behavior, sociability, and personality, such as anger expression, were surveyed from 1,295 adolescents (666 in Seoul, 316 in Changwon, and 313 in rural communities), and then analyzed using SPSS program. The results are shown as follows. The fast food preference score and the fast food intake frequency score showed no differences between male students (22.9/30, 14.4/30 respectively) and female students (23.0/30, 14.0/30 respectively). But, the fast food preference score correlated positively with the intake frequency score (r=0.304) significantly (p<0.001). The more frequently eating of fast food group showed significantly lower scores (r=-0.233, p<0.001) in food behaviors. The frequency of fast food intake had no relationships with sociability, but it had a significantly effect on anger expression (r=0.213, p<0.001) and control (r=-0.l47, p<0.001). From these results, we could see the necessity of various nutrition education programs to build proper eating-out habits and also more studies are needed to find the relationships between fast food intake and growth and personality.

BACKGROUND/OBJECTIVES: Hypertension is the major risk factor for cardiovascular disease, a leading cause of deaths in Korea. The objective of this study was to evaluate the effect of a nutrition education in reducing sodium intake and increasing potassium intake in hypertensive adults. SUBJECTS/METHODS: Subjects who participated in this study were 88 adults (28 males and 60 females) who were pre-hypertension or untreated hypertensive patients aged ≥ 30 yrs in Gyeonggi Province, Korea. These subjects were divided into 2 groups: a lowsodium education (LS) group and a low-sodium high-potassium education (LSHP) group. Nutrition education of 3 sessions for 12 weeks was conducted. Blood pressure, blood and urine components, nutrient intake, and dietary behavior were compared between the two education groups. RESULT: Blood pressure was decreased in both groups after the nutrition education (P < 0.05). In the LSHP group, levels of blood glucose (P < 0.05), total cholesterol (P < 0.01), and lowdensity lipoprotein-cholesterol (P < 0.05) were decreased after the program completion. Sodium intake was decreased in both groups after the nutrition education (P < 0.05). However, Na/K ratio was only decreased in the LS group (P < 0.05). Intake frequency of fish & shellfish was only significantly reduced in the LS group (P < 0.05), while intake frequencies of cooked rice, noodles & dumplings, breads & snacks, stew, kimchi, and fish & shellfish were reduced in the LSHP group (P < 0.05). Total score of dietary behavior appeared to be effectively decreased in both groups after the education program (P < 0.001). CONCLUSIONS: This education for reducing sodium intake was effective in reducing blood pressure and sodium intake. The education for enhancing potassium intake resulted in positive changes in blood glucose and serum cholesterol levels.

Dietary behavior, body mass index(BMI) and nutrient intake status of 185 boys and 205 girls in 3rd grade middle school students in Daegu area were analyzed. Boys were 168.6cm tall and weighed 61.3kg on the average and girls 158.5cm and 54.4kg, respectively. From their BMIs, 17.9% were classified as the underweight, 54.2% as the average, 14.7% as the overweight and 13.2% as the obesity. The average energy intake per day was 2222.6 kcal for boys, 1796.2 kcal for girls which were 83.3% and 86.6% of the RDA, respectively. Composition rate of carbohydrate, protein, fat in relation to energy intake was 62.4 : 16.5 : 21.1 for boys and 58.8 : 16.0 : 25.2 for girls. Protein was taken low and carbohydrate and fat were high in this study. Particularly, fat intake rate of girls was high. Calcium, iron, vitamin A, and vitamin B2 did not meet the RDA and especially calcium was taken 63.9% for boys and 54.01 % for girls. Most of the students have tendency to eat irregularly and to overeat. For the nutrients intake, calories and calcium intake were lower than the RDA regardless of gender and iron intake was not enough for girls only. In relation to BMI, obesity group students were taking lower calories and proteins than the normal students were. No consistent trend was shown for boys about nutrient intake in relation to eating speed. Students had a correct perception of their body image which was similar to that of their mothers. Nutrient average intake is under the average and the percentile under 70% of RDA was high contrary to the fact that nutrient intake like calcium and iron was exceedingly important particularly in the growth process. Therefore, nutritional education for the proper intake of nutrients was required for the students in Daegu area. Especially, education has to be focused on the balanced diet and correct food choices for the proper dietary behaviors.

For the correct dietary habit and balanced dietary intake of aged people, the nutrition management that fits to the dietary behavior change stage has to be accomplished. In order to do so, in this paper, we chose 175 women that are aged more than 65 years old who are rural long life community residents and surveyed the dietary intake for 2 days including a twice depth interview and the 24 hour recall method. Also, for the sake of our aim, using the transtheoretical model, the dietary behavior change stage group was divided into the contemplation stage group, the preparation stage group, the action stage group and the maintenance stage group. The results are as follows: In the intake amount of protein (p < 0.01), vitamin $B_1$ (p < 0.05) and vitamin $B_6$ (p < 0.05), the intake amount of these nutrients in the action stage group and the maintenance stage group were significantly larger than the intake amount in the contemplation stage group and the preparation stage group. The nutrition evaluation according to the dietary behavior change stage, the ratio of subjects who took insufficient amount of energy, protein, vitamin A, and vitamin C were low as the dietary behavior change stage was upgraded. The subjects of maintenance stage group were most likely to consume vegetables more than once a day, and consume fruits and milk and milk products more than 5 times/week. MAR [13], MAR [10] and MAR [4] of subjects in the action stage group and the maintenance stage group were significantly higher than MAR [13], MAR [10] and MAR [4] of subjects in the contemplation stage group and the preparation stage group (p < 0.001). From the above results, there were differences of nutrient intakes according to the dietary behavior change stage. Therefore, it is considered that the intervention for the dietary behavior motivation induction has to be advanced before accomplishing the individually fitting intervention at the time of nutrient management intervention.
