The aim of this study was to determine whether Nutrition Quotient (NQ) for children, which has been developed from data on urban children, can be applied to children in rural areas. A total of 200 children (108 boys and 92 girls) in fifth and sixth grade at three elementary schools in rural areas of Gyeongbuk participated in the survey conducted during June 2012. Questionnaires consisted of items on food intake frequency and dietary behavior. Food intake data were obtained using the 24-hour recall method, and nutrient intake was calculated using the CAN-Pro 4.0 Program. Percentages of children who took less than the estimated average requirement were 76.5%, 49.5%, 45.5%, 33.5%, and 26.0% for calcium, vitamin C, iron, vitamin A, and folate, respectively. Significant associations were observed between intake frequencies of vegetables, kimchi, and fruits, and intake of vitamin C, folate, and dietary fiber. White milk and legumes showed positive correlation with intake of calcium and vitamin A. Eating breakfast, meal regularity, and diverse side dishes showed positive correlation with intake of folate and calcium. The 19 food checklist items could be categorized according to five factors. The mean NQ score of the subjects was 62.0, which was similar to that of urban children, 64.4. NQ score and factor scores for balance, regularity, and practice were significantly lower in children with lower socioeconomic level as compared to those with higher socioeconomic level. Higher NQ score showed an association with increased intake of vitamin B2, folate, vitamin C, and calcium. In conclusion, NQ offers a valuable instrument for evaluation of food habit and dietary quality of rural children as well as urban children, and children with low socioeconomic status should be monitored by testing with NQ checklist before implementation of nutrition programs.

This study was performed to compare dietary behaviors based on residence types of female college students. Self reports on dietary behavior and one-day dietary records were obtained from 227 female college students using anonymous questionnaires. The mean age of the subjects was $20.4{\pm}1.43$, and the height and weight were $162.5{\pm}4.8cm$ and $52.3{\pm}7.9kg$, respectively, The dietary behavior of female college students was inadequate, showing indifference to dietary balance, irregularity of meals, skipping breakfast, and high experience of drinking. One-day dietary records were obtained from 24k recall methods also showed a high number registering skipped meal status ($55.3\%$) and less diverse food intake (DVS, 12.5; DDS, 3.93). The students in self boarding residence were especially more likely not to eat properly and their dietary behaviors were found to be significantly poor. In the case of home residence, food intake frequency scores for milk and dairy products, fruits, and fishes were significantly higher, however the students in self boarding residences showed high food intake frequency scores in salted food, retort food, canned food, and especially instant ramyun. Therefore, more attention needs to be given to them to recognize the problems in their own dietary behaviors and more practical nutritional supports, like developing a menu for breakfast in college cafeterias, would be helpful to improve their dietary choices.

Objectives: This study investigates dietary supplement intakes by examining the characteristics of dietary and health-related behaviors. Data were obtained from the Korea National Health and Nutrition Examination Survey (KNHANES). Dietary and health-related behaviors were also examined before and after the occurrence of COVID-19 and household types (multi-members vs. single person). Methods: Data used in this study were collected from the 2019-2020 KNHANES by including adults aged 19 to 64 years. Pregnant, lactating, and subjects consuming calories less than 500 and more than 5,000 were excluded. Differences in dietary and health-related behaviors before and after COVID-19, and between the two types of households were analyzed by Chi-square analyses using Rao-Scott. Logistic regression analyses were applied to determine which dietary and health-related behaviors affected the dietary supplement intakes. In addition, descriptive analysis was run for demographic characteristics. Results: The dietary supplement intake rate differed significantly with respect to the gender, age, education, marital status, and household income. Dietary supplement intakes, frequency of eating out, obesity, and body weight changes were significantly different before and after COVID-19. In addition, meal evaluation, frequency of eating out, drinking, smoking, activity, subjective health evaluation, and body weight changes showed significant differences by household type. Attitude towards nutrition, activity, meal evaluation, obesity, and smoking were factors that affected the intake of dietary supplements. Conclusions: While increased intake of dietary supplements is a prevalent phenomenon, this intake needs to be monitored and studied closely, considering the sociodemographic characteristics and dietary and health-related behaviors. Furthermore, the dietary supplement intake trend after COVID-19 needs to be studied along with food intake.

Purpose: Sodium intake in school meals is very high. Accordingly, many health problems have emerged. The objective of this study was to assess school dietitian's awareness and practice of sodium contents in urban and rural locations schools and suggest sodium reduction plan in school meal service. Methods: A total of 524 nationwide school dietitians from elementary, middle, and high schools in south Korea were surveyed using questionnaires to determine their awareness and practicing behavior for reducing high-salt contents in meals. Sodium reduction plan was then suggested accordingly. Results: Most school dietitians (83%, n=436) were aware of the necessities of sodium reduction in school meals. They were aware of optimum sodium levels at 700-1000 mg. However, the percentages of dietitians who had practicing behavior of using measuring utensils for seasoning were 20.7% (n=108), 14.9% (n=78), and 13.5% (n=71) in elementary, middle, and high schools, respectively (p<0.001). Dietitians in urban elementary and middle schools had significantly (p<0.01) higher practicing behavior of using measuring utensils compared to those in rural locations. Considering low levels of soup contents with high amount of leftover, the desirable soup portions to be reduced were '50-100 mL' (n=66, 12.7%) for elementary school and '100-150 mL' for middle school (n=62, 12.0%) and high school (n=57, 11.0%, p<0.001). Conclusion: Dietitians' awareness for sodium reduction was high but their practicing behavior was relatively low. Thus, continuous efforts are required to develop reduced-sodium menu by promoting the use of measuring utensils when preparing meals and by planning no soup meal day or educating students and teachers about the importances of reducing sodium in school meals.

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.

This study was conducted to investigate the relationship between body image and BMI with satisfaction of own body image, snack intake practices, food intake practices and weight control practices of 226 female college students in Jeonbuk province using questionnaire. The results were summarized as follows : 1. The average height, weight and BMI was 162.08cm, 52.02kg and 19.78, respectively. The average ideal body weight of the subjects was 48.92kg. Ninety percent of the subjects was dissatisfied with their body image. The degree of dissatisfaction was higher in the group who recognized themselves as fat. Most of subjects wanted to lose weight, but as the group having a recognition of thin body image significantly wanted to gain weight (p<0.001). 2. The subjects preferred fruits and juices for snack. The more subjects recognized themselves as fat, the more they restricted snack intake (p<0.05). 3. The rate of skipping meal tends to increase. The subjects did not intake balanced meals and skipped breakfast most (20.7%). The number of food groups taken at breakfast, lunch and dinner was 1.84, 2.25 and 2.55, respectively and the most variable food groups were taken at dinner(p<0.001). Dairy food group intake was low. The duration of meal time was longer in the underweight group by BMI regardless of body image recognition (p<0.05). 4. The weight controlling method was concentrated mostly on decreasing food intake. The more subjects recognized themselves as fat, the more they tried to control weight (p<0.001). Even though 59.5% of the subjects with no weight control experience had no future weight control plans, 50% of the group who recognized themselves as normal or fat did not want to control weight in the future (p<0.01). These results suggest that nutrition education programs and correction programs of food behaviors and weight control should start from focusing on the accurate recognition of body image for college female students.

The study examined the perceived health status, dietary habits, and health-related lifestyle habits of middle-aged men and women in Seoul and Gyeonggi-do areas. The survey was conducted on 670 individuals (320 men and, 350 women), aged 40~64 years, in Seoul and Gyeonggi-do areas. The online and written data were analyzed using the SPSS WIN 25.0 program. Although there was a significant difference in the perceived health status (P < 0.01), there were no significant differences in the subjective stress and the current disease status according to sex. For dietary habits, the scores for fruit intake (P < 0.05), meat and fish intake (P < 0.05), milk and dairy products intake (P < 0.01), and seaweed intake (P < 0.05) were higher in women than men. The scores for three-meal eating (P < 0.05) and water intake (P < 0.01) were higher in men than women. For the health-related habits, alcohol-drinking frequency, daily alcohol consumption, smoking experience, and daily smoking were higher in men than women (P < 0.001). In contrast, caffeinated beverage intake, exercise frequency, and daily smart-phone, computer, and TV using time were similar in both sexes. The meal-eating time was faster in men than women (P < 0.01). For dietary behavior changes, only appetite showed a significant gender difference (P < 0.05). This study provides essential information on the perceived health status, dietary habits, and health-related lifestyle habits in middle-aged men and women. Nevertheless, further research and a practical nutrition program will be needed to solve undesirable dietary habits and improve the health and lifestyle of middle-aged adults according to sex.

This study was conducted to measure the effect of a community-based nutritional intervention program on dietary behaviors and nutrient intakes of low-income elderly women in Korea. The subject of the study was a group of 88 elderly women using the free meal service in Dong-gu, Gwangju city in Korea. The study was carried out from April to July 2009, and the pretest, application of nutrition education, and post-test were applied in each stage. This community-based nutrition intervention program consisted of snack supplement and nutrition education provided three times a week and 36 times in total. The nutrition education was led by the nutritionists and professionals using various educational media. Snack supplement included were milk, soymilk, carrot juice, bread, yogurt, and bananas. The result of pretest showed that the nutrient intakes of the subjects were much below the Recommended Nutrient Intake (RNI) level of Dietary Reference Intake for Koreans. Comparison of the dietary behavior score and nutrient intakes before and after the nutritional intervention program indicated that the food behavior score increased from 3.1 to 5.6 (P<0.001) and intake of energy, protein, carbohydrate, thiamin, niacin, vitamin C, iron, and potassium of the subjects all increased significantly (P<0.05). Mean Adequacy Ratio (MAR) of their nutrient intakes was also improved from 0.53 to 0.64 (P<0.01). These results indicated that the nutrition intervention program conducted in this study was effective in improving dietary behavior and nutrient intakes of elderly women in local community.
