Objectives: This study was conducted to investigate the status and need for nutrition and dietary life education among nutrition teachers at schools. These characteristics were analyzed if they were different between elementary schools and middle-high schools. Methods: Subjects were 151 nutrition teachers from 70 elementary schools, 41 middle schools and 40 high schools in 17 cities nationwide selected by two-stage stratified cluster sampling process. Survey questionnaires included the items on general characteristics, status and need assessment for nutrition and dietary life education. Chi-square test or t-test was used for data analysis by school groups. Results: Nutrition education was implemented at 65.7% of elementary schools and 51.9% of middle-high schools. Nutrition education was mainly performed in 'discretionary activities extracurricular activities' at elementary school and through 'newsletters, school homepage, foodservice bulletin board' at middle-high school (p<0.001). The most needed topic for nutrition education in nutrition teachers was 'healthy dietary habits and table manners' and this was not significantly different by school groups. Responses on adequate frequency (p<0.01), methods used for nutrition education (p<001), materials for nutrition education (p<0.001), information sources for nutrition education (p<0.001) were significantly different by school groups. Major tasks for activating nutrition education included 'securing the time for implementing nutrition education by reducing work loads' and 'developing standardized nutrition education materials' in schools. Conclusions: Nutrition education at schools might be activated by improving working conditions of nutrition teachers and developing the practical programs that reflect the needs of nutrition teachers.

Objectives: This study aimed to investigate the changes in the eating habits and lifestyle of middle-aged women in Gwangju during the COVID-19 pandemic. Methods: A total of 428 middle-aged women aged between 40 and 60 participated in a survey relating to general information, food and lifestyle, health functional food, and menopausal symptoms. The correlation between the variables was analyzed. Results: In the positive habits, the intake of nutritional supplements for immunity enhancement increased the most, followed by the use of media to learn healthy eating tips, and diets including healthy food. Negative habits increased in the order of frequency of taking delivery orders, levels of stress or anxiety, and time spent sitting or watching movies. In the case of recommended foods, the intake increased the most in the order of eggs, fruits, vegetables, milk/dairy products, and seaweed. Non-recommended foods increased in the order of meat, bread, rice, and noodles. The awareness of health functional foods was in the increasing order of interest, knowledge, consumption experience, and purchase amount. The type of health functional food intake was in the increasing order of probiotics, multivitamin and mineral supplements, vitamin C, collagen, and omega-3. Menopausal symptoms were in the increasing order of bone and joint pain, poor sleep quality, emotional ups and downs, loneliness, and feeling of emptiness. In the correlation of major variables, positive habits showed a significant positive correlation with recommended food intake and the recognition of health functional foods. Negative habits showed a significant positive correlation with non-recommended food intake and a significant positive correlation with menopausal symptoms. Recommended food intake showed a significant positive correlation with health functional food recognition and intake and menopausal symptoms. Conclusions: This study suggests that it is necessary to establish social measures to reduce the negative effects of the COVID-19 pandemic on middle-aged women and to ensure effective self-management through a healthy lifestyle since the pandemic has a long-term impact.

The purpose of this study was to investigate effects of nutrition education program and pamphlet for the lower grades elementary students focused on individual daily needed food exchange units using Food Exchange System. Program consisted of four lessons (40 min/lesson), "5 major nutrients & function", "6 food group and sources", "daily needed food exchange units for normal body weight", and "smart snack choice and exercise". Pamphlet as activity book was developed for the program. The subjects were 3rd grade elementary students (educated group, 31 vs. non-educated group, 31). Educated group were lessoned as group and/or individual. We examined the differences in nutrition knowledge, dietary attitudes, dietary intakes and satisfaction of the program and pamphlet. In educated group, there were positive improvements on nutrition knowledge score "function and foods of 5 nutrients" and on dietary attitudes "type of breakfast and snacks". In the evaluation of dietary intakes according to KDRI, there were positive improvements on intakes level of riboflavin, vit. C, folate, Ca, P, Fe and Zn in educated group. In satisfaction with the program and pamphlet, contents, font size, visual, figure, difficulty and program curriculum were over 2.90/3.0. It showed that the developed nutrition education program and pamphlet focused on individual daily needed food exchange units using Food Exchange System improved nutrition knowledge, dietary attitudes and nutrients intake level in the lower grades elementary students.

This study was performed to investigate the relationships between obese index and major risk factors of cardiovascular disease in CVD patients. Anthropometry, food intake patterns, blood pressure, serum lipids and hematological values were analyzed in 550 patients from June, 1991 to August, 1992. The results are as follows: Total food intakes, especially total vegetable food and alcohol intakes were significantly related with obese index, so that the heavier patients tended to consume more carbohydrate and less fat. The blood pressure were observed to have positive correlation with obese index in man but not in women. However, both in men and women, blood levels of TG, TC, and VLDL tended to be related to obese index positively, while HDL and HDL-C were shown to be oppositive. So, it seems that as the degree of obesity is higher the blood pressure and blood lipids patterns worse. Therefore, these results suggest that obesity is one of the major risk factors of CVD, and for prevention & treatment of the disease, controlling body weight by nutritionally adequate diet along with alcohol restriction is necessary.

To promote health status, strategies and interventions to improve nutrition should be based on the proper diagnosis of the subject's eating patterns. The elderly usually have traditional food habits and preferences, and it is very difficult to change them. This study was designed to identify dietary behavior and food preference of the elderly, in order to provide baseline data for the Elderly Nutrition Intervention Program for the Public Health Center. A survey questionnaire was made for use by trained interviewers to query 151elderly people from 5 community elderly centers located in Suwon, Korea. The majority of them ate regularly and partook of all available side dishes. Their major dietary problems were frequent consumptions of salty foods, and eating too quickly. They consumed grains and vegetables regularly, but seldomly ate dairy products, fruits, meat and food prepared with oil. They also tended to eschew ready made processed food, high cholesterol food, and fast food. Also they did not dine out as much as younger people. Desirable eating habit score were not significantly influenced by socioeconomic variables and nutrition-related characteristics. These included nutrition knowledge, Nutritional Risk Index(NRI) and a score of health concerns. However, meal balance scores were significantly higher in the younger group(p<.05), the higher household income group(p<.05). According to stepwise multiple regression analysis, NRI was the most important determinant of a desirable eating habit score for the male elderly, whereas the score of health concerns was mo9st important for female elderly subjects. The greatest predictor of the meal f balance score was nutrition knowledge. The elderly liked sweet tasting food, grains, rice, stews and Korean style soups. They disliked sour food, dairy products, processed food, and bread. The results indicate that the Elderly Nutrition Education Program should focus on increasing consumption of dairy products, fruits and food with oil, prepared by traditional Korean cooking methods. It also suggests that the program planning should consider the socioeconomic status of the elderly, such as income and education level, as well as concern for health.

This study was performed to evaluate effects of dietary variety scores (DVS) and dietary diversity scores (DDS) on the nutritional quality of the diets of Korean college students, and to examine the association between food group intake patterns and nutritional adequacy. This study examined the relationship of dietary diversity scores (DDS), dietary variety scores (DVS), and food group intake patterns with nutrient intakes using 24-hour recall data (n=.358). The .DDS was calculated from the sum of each of the five food groups consumed as a score of 'I'. DVS was determined by counting the number of food items consumed daily. Food group intake patterns were expressed with the presence or omission of five major food groups-dairy, meat, grain, fruit, and vegetable. The four most prevalent food group patterns and the proportion of the population reporting them were as follows; no dairy and fruit, $23\%;\;no\;dairy,\;20\%;$ no dairy, meat, and fruit, $15\%$; all food groups, $14\%$. Even though the DDS or DVS was higher, the majority of this study population failed to meet the Korean RDA for calcium in both genders and iron in women. Higher DVS scores $(\geq31)$, within all DDS groups, were associated with the largest proportion of individuals consuming more than $75\%$ of the Korean RDA for selected nutrients. The consistency of these results indicates that screening diets to evaluate the overall dietary variety and variety among the major food groups including food group intake patterns provide meaningful information about their quality.
