The purpose of this study was to develop of nutritional education activities and effect evaluation in related curriculums for all Dongbu Elementary School children in Jinhae by the teacher in charge. This educational purpose was to build a desirable dietary behavior for optimal growth and health in elementary school children. The educational program contents were developed according to 1) selection of content related curriculums 2) analysis of contents related on dietary habits by grade 3) preparation teaching plans to build desirable dietary habits 4) development of teaching manual by turns. Twelve hours of nutrition education at all school classes were done from March 2 to December 10 2004 in Dongbu Elementary School in Jinhae, Gyeongnam. The education effects were evaluated through the questionnaire surveys before and after the education and their comparative analysis. The results of this study were summarized as follows : Forty percent of the underweight group, $22.8\%$ of the normal group, $42.2\%$ of the obese group had the wrong perceptions on their body figures, but after nutrition education $80.5\%$ of the underweight group, $94.3\%$ of the normal group, $97.9\%$ of the obese group gleaned the correct perceptions on their body figures (p < 0.001). As the effects of the education, the subjects who exercise more than 3 times in a week increased in all groups (p < 0.01-0.001), notably in the obese group. Meal regularity (p < 0.001) , skipping meals (p < 0.001), eating rate and snack selection patterns (p < 0.01-p < 0.001) also improved by nutrition education. We could also observe the effects of the nutrition education through the affirmative statements which appeared in their dietary records. These results showed a possibility of nutrition education activities in related curriculums to improve in dietary habits of school children. Next year, we will start with the system of nutrition teachers in elementary school, but nutrition teacher cannot undertake the task of teaching and food service management alone. Because of that, we intend to develop this program as an alternative proposal for the nutrition education in elementary schools. (Korean J Community Nutrition 10(6) $795\∼804$, 2005)

In order to investigate the ecological factors affecting milk intake frequency of adolescents, the questionnaire survey was conducted with 929 middle and high school students living in Chungnam urban area through October and November 2004. The subjects consumed milk 8.6$\pm$6.7 times per week, other beverages 4.4$\pm$4.1 times per week and drinking water 3.7$\pm$2.1 cups per day. Of the students 77.3% took balanced meals, 72.8% ate regularly and 36.2% ate adequate amount. About 61% had breakfast everyday and nearly a half students snacked once a day. Nutritional knowledge scores about milk was 7.2$\pm$1.7 and milk attitude scores was 28.1$\pm$6.5. The subjects spent daily 1.8$\pm$1.1, 1.9$\pm$1.1, and 1.0$\pm$0.5 hours for computer use, TV watching and exercise, respectively. Milk intake frequencies were positively correlated with excercise, snack frequency, meal balance and regularity, breakfast frequency, food attitude score and milk preference, while showed negative correlationships with TV watching and computer use. Intake frequency of fruit-tasted and chocolate milk showed inverse correlation with nutritional knowledge. Subjects without either school store or vending machine took milk more frequently than those with one or both did. Of the correlated variables, milk preference was the most important influencing factor to milk intake frequency according to the stepwise linear regression analysis, which presented other 5 important influencing factors as food attitude, school vending facilities, excercise, snacking frequency and watching TV. In conclusion, the improvement of milk preference is the most important and effective way to promote milk consumption in adolescents. The favorite ways of drinking milk, nutritional benefit of milk, healthy beverage and good snacking should be taught in nutrition education. Also physical activities should be recommended to students rather than watching TV, computer use and vending facilities selling soft drinks should be limited to be established inside school.

Purpose: The goal of this study was to examine body image satisfaction and perception according to weight status, and to investigate those associations with dietary habits and nutritional status among preadolescent children. Methods: Body image and dietary habits and intake were assessed in 134 elementary school students in grade 4. Children were categorized according to normal and overweight or obese groups. Figure rating scales were used to assess body image perception (identification of perceived current body size) and dissatisfaction (difference between perceived current body size and ideal body image). Results: There were sex differences in body image perceptions. Normal-weight girls, overweight or obese girls and boys were more likely to desire a leaner body size than their perceived body size compared with normal-weight boys. Body image satisfaction and perception showed an association with weight status. More overweight or obese children indicated dissatisfaction or underestimation of body image than normal-weight children. Children with body image dissatisfaction due to heavier perceived body size than ideal body image showed lower frequencies of consumption of meals and vegetables, compared to those who were satisfied with their body image. Children who underestimated their body image were more likely to have a lower frequency of breakfast and meal regularity and a higher frequency of eating out of home or food deliveries than those with accurate body image perception. In addition, body image underestimation showed an association with lower intakes of protein, dietary fiber and calcium, and the higher percentage of calories derived from fat. Conclusion: Body image dissatisfaction as well as underestimation in children before puberty showed an association with overweight or obesity, and was also related to unhealthy dietary habits. These findings highlight the importance of accurate perception and satisfaction with body image in preadolescent children in order to prevent development of obesity in adolescents and adults.

This study examined to find out the relationship between nutritional knowledge and food habit of the students majoring food & nutrition(218 students) and the students majoring Korean oriental medicine(286 students). The results of this study are as follows; 1)The intake of vegetable and dairy products is high for the students majoring food & nutrition(p＜0.01), and the intake of instant food is low for the students majoring Korean oriental medicine(p＜0.01). 2)In the value of diet, the ratio which acknowledges the importance of the relationship between the diet and the nutrients is high for the students majoring food & nutrition (p＜0.01), and the ratio which acknowledges the diet as the way to remove hunger or to enjoy eating is high for the students majoring Korean oriental medicine(p＜0.01). The ratio of the students who acknowledge taste, nutrition and preference as the important factors in selecting foods is high for the students majoring food & nutrition(p＜0.01). The ratio of regularity in each meal, consuming time, and the food quantity is high for the students majoring Korean oriental medicine(p＜0.01). 3)The total score of 20 inquiring items about nutritional knowledge is high for the students majoring food & nutrition(p<0.01), and especially the mark is high in such items inquiring the relationship between animal fat and nutrition(p<0.01), the relationship between water and obesity(p<0.05), the relationship between cholesterol and food(p<0.01), the recommended energy quantity(p<0.05), and the vitamin B group (P<0.01). According to this study, it is hard to determine that there is inevitable positive relationship between diet habits and nutritional knowledge. The students majoring food and nutrition know better than the students majoring Korean oriental medicine about the relationship between diet, health and nutrients however they can not practice what they blow when selecting foods. On the other hand the students majoring Korean oriental medicine show lower marks in food habits and nutritional knowledge than those of the students majoring food and nutrition; however, they show higher marks in practicing regular diet. According to this result it is necessary to increase the subjects related nutrition in the curriculum not only lot the students majoring food & nutrition to practice their nutritional knowledge in their actual life but also for the students majoring Korean oriental medicine to obtain correct nutritional knowledge and information.

The purpose of this study was to investigate the effects of weight control program on dietary habits and blood composition in obese middle-aged women. The program consisted of nutrition education, physical exercise and nutrition counseling was conducted for 12 weeks. Participants of the preliminary study were 255 obese women, among which 82 women participated in the nutrition education program. We evaluated the anthropometry, blood lipid profiles, dietary habits of obese women before and after the nutrition education. Dietary habits of the subjects were significantly improved in regularity of having breakfast (p < .05), the frequency of eating snack after dinner (p < .001), eating out (p < .01) and the speed of meal (p < .05) after the program. There was significant decrease in total cholesterol, triglyceride, LDL-cholesterol and systolic pressure of the subjects after nutrition education. Changes of atherogenic index and diastolic pressure were not significant, but had a tendency to decrease. All of the anthropometric outcomes except lean body mass such as BMI, percent body fat, fat mass, and WHR were significantly decreased after weight control program. These findings show that weight control program including nutrition education and counseling can improve dietary habits and weight control pattern, and lead the authors to recommend that public health organizations and dietetic professionals should educate obese women on practical strategies for an effective weight management.

BACKGROUND/OBJECTIVES: The study was performed to investigate health-related lifestyle, dietary habits, and depression according to exercise frequency to understand complex factors that affect effective health management. Thus, exercise frequency, health-related lifestyle, dietary habits, and depression were evaluated in college students in Seoul and Gyeonggi-do areas. SUBJECTS/METHODS: A survey was conducted on college students, aged 19-29, in Seoul and Gyeonggi-do areas from May 13 to May 31, 2020. A total of 594 questionnaires were collected and 566 (269 from males, 297 from females) were statistically analyzed, except 28 with incomplete responses. Collected data were analyzed using SPSS WIN 21.0 program. RESULTS: The sex distribution of the 3 groups according to exercise frequency was significantly different; the ratio of males in over 3 times/week group was significantly higher than those in 1-2 times/week group and no-exercise group (P < 0.001). The height (P < 0.001), weight (P < 0.001), and body mass index (P < 0.05) were significantly higher in over 3 times/week group compared to no-exercise group. The ratio of subjects who answered 'good' or 'very good' for subjective health condition was significantly high in the order of 'over 3 times/week' group (59.1%), '1-2 times/week' group (34.5%), and 'no-exercise' group (25.0%) (P < 0.001). The ratio for meal regularity was high as 56.6% in 'over 3 times/week' group and the ratio for irregular meals was significantly higher in 'no-exercise' group (67.2%) and '1-2 times/week' group (54.9%) (P < 0.001). Among questions on dietary habits, 'Eat meat, fish, egg or beans' (P < 0.01) and 'Eat fruit' (P < 0.01) were significantly higher in 'over 3 times/week' group compared to 'no-exercise' group. 'Drink more than 2 liters of water' (P < 0.001) was 0.70 in 'over 3 times/week' group, which was significantly higher than 0.54 in '1-2 times/week' group and 0.38 in 'no-exercise' group. Moderate depression and severe depression that need treatments were significantly lower in 'over 3 times/week' group (18.7%) compared to '1-2 times/week' group (26.0%) and 'no-exercise' group (29.7%) (P < 0.05). CONCLUSIONS: It is considered that combined intervention for exercise habits, proper dietary habits, and depression management is needed for effective health management.

This study was conducted in order to investigate and compare anthropometric measurements, bone density, nutrient intake, blood composition and food habits between non-smoking, non-alcohol drinking and smoking, alcohol drinking male university students in Seoul, South Korea. The data for food habits and health-related behaviors were obtained by selfadministered questionnaires. The BQIs of the subjects were measured by Quantitative Ultrasound (QUS). The subjects were divided into two groups: NSND (non-smoking and non-alcohol drinking, n=62) group and General (smoking and alcohol drinking, n=160) group. The results were analyzed using the SPSS program and were as follows: The average heights, weights, and BMIs of the two groups were 173.3 cm, 66.5 kg and 22.1 and 173.4 cm, 68.7 kg and 22.9, respectively. There were no differences between the groups regarding height, weight or BMI. SBP and DBP, however, were significantly higher in the general group than in the NSND group (p<0.01). The BQIs, Z-scores and T-scores of the two groups were 99.83, -0.23, and -0.31 and 98.24, -0.27 and -0.39, respectively, producing no significant differences between the two groups. The percentages for normal bone status, osteopenia and osteoporosis were 83.88%, 16.12% and 0.0% and 74.37%, 25.62% and 0.01%, respectively. Mean intakes of animal protein (p<0.05), animal fat (p<0.05), fiber (p<0.05), animal Ca(p<0.05), animal Fe (p<0.001), Zn(p<0.05), vitamin B1 (p<0.05) and niacin (p<0.05) were significantly different between the two groups, and mean serum levels of SGOT (p<0.01), SGPT (p<0.001), ${\gamma}$-GTP (p<0.001), triglycerides (p<0.01), total cholesterol (p<0.05) and hematocrit (p<0.05) were also significantly different between the two groups. Overall, there were no differences in meal regularity, frequency of snacking, reasons for overeating, exercise and defecation between the groups. However, favorite foods (p<0.05) and night-time meals (p<0.05) were significantly different. In conclusion, the health status of the NSND group was superior compared to the general group. Thus, students who smoke and alcohol drink should receive a practical and systematically-organized education regarding the increased health benefits of quitting smoking and alcohol drinking.

The purpose of this study was to investigate the dietary habits, health status, and nutrients status of male college students in Seoul according to vegetarian habits. The heights of lacto-ovo vegetarian and non-vegetarian students were not significantly different. However, body weight was significantly higher in the non-vegetarians. The lacto-ovo-vegetarians were vegetarians for religious reasons, and indicated 86.0% satisfaction with their meals. However, the lacto-ovo vegetarian and non-vegetarians showed concerns about low nutrient intakes. Lacto-ovo vegetarians displayed a higher proportion of meal regularity and daily breakfast as compared to non-vegetarians. In addition, their favorite food when eating out was Korean food. Lacto-ovo vegetarians showed higher intakes of milk or other dairy products (yogurt, etc.), vegetables, and fruit, as well as more regular eating habits. In contrast, the non-vegetarians showed higher intakes of high-protein foods (eggs, beans, tofu, etc.) and fatty foods. Lacto-ovo vegetarians showed lower intakes of total energy, as well as vitamins $B_2$, $B_6$, and niacin. Non-vegetarians showed in sufficient dietary fiber intake. In conclusion, lacto-ovo-vegetarians need a meal plan to consider the intake of other nutrients, while non-vegetarians should try to prevent the occurrence of health problems due to excessive intake of nutrients.
