The purpose of this study was to examine the research trend of nutrition for the recent 12 years from 1996 to 2007 by analyzing 734 articles published in the Korean Journal of Community Nutrition. The majority of the articles (61.4%) were classified as survey types in terms of data collection methods. Most of the subjects used in the articles were adults (28.8%), and the subject whose research has been increased at the highest rate was "patients". The most frequent keywords in the title of articles were "nutrient intake" (231times), "food service" (92times), "dietary habits" (69times), and "obesity" (69times). The keywords that have appeared more frequently with the years were "osteoporosis" (450.0%), "menopause" (350.0%) and "dietary attitudes" (208.3%). As for research interests, "nutrient intake" was dominant in the early stage of research while "disease", "dietary habits", "dietary attitudes" and "nutrition education" have increased in recent years. Some of the most common methods of nutrition assessment were "dietary intake" (41.2%), "anthropometric" (34.0%) and "biochemical test" (14.7%). The most common methods of dietary intake were "24-hours recall" (28.6%) and "dietary habits" (23.3%). The results of this study showed some biases in data collection methods, gender of the subjects, and study areas. Moreover, inconsistent terminologies, questionnaire contents, and measures were used for the researches on dietary behaviors, dietary habits, dietary attitudes, which made it difficult to compare their results for each research. Therefore, standardized research methods and terminologies need to be developed regarding dietary practices.

The purpose of this study was to evaluate the effect of nutrition education on dietary knowledge, dietary attitudes, and dietary behavior of elderly by analyzing changes before and after nutrition education. This study was conducted in Seoul from March 2022 to December 2022 for 50 elderly (6 male, 44 female) who participated in nutrition education for 8 weeks at three senior welfare centers (Seodaemun, Seongbuk, Jongno). A total of 35 responses were used in the final analysis. Statistical analysis was conducted using descriptive statistics, paired t-test, and Wilcoxon's signed rank test by age, hypertension, and dislipidemia to find effect of nutrition education on their nutritional knowledge, dietary attitudes, and dietary behavior. Results showed that nutrition education had a significant effect on the elderly. In particular, for those with chronic diseases such as hypertension and dislipidemia, the difference after education was significant, indicating significant changes in dietary habits. This study is expected to provide basic data for the development of a systematic nutrition education program for the elderly in the future.

We examined the obesity levels and dietary habits of 323 college students taking the course 'Health and Diet' as a part of their nutritional education. The average percentages of body fat, BMI and RBW for subjects in this study were 16.7%, $21.5kg/m^2$ and -1.2% in male students and 27.3%, $21.2kg/m^2$ and 1.0% in female students, respectively. BMI and RBW indicated fewer cases of obesity among female students than BIA did. The average intake of energy by subjects was lower than the RDA of energy. In particular, the average intakes of calcium, iron, and vitamin A by female students were much lower than the RDA of energy. In particular, the average intakes of calcium, iron, and vitamin A by female students were much lower than the RDAs of each of those nutrients. The percent RDAs of nutrient intakes of energy, protein, thiamin, and riboflavin were lower in under weight students than in students of normal and over-weight. Female students were found to skip meals and consume sweet foods more frequently than male students. The obesity levels of students related to the number of meals eaten per day as well as the frequency of consuming sweet foods. Although, it was not possible to determine statistically, the levels obesity also seemed to correspond to the speed at which meals were eaten as well as the frequency of eating salty foods. These results suggest that in order to assess obesity properly, more research that focuses on subjects' gender should be conducted. In addition, nutritional education should emphasize the importance of intakes of energy and phosphorus for male students, and the danger of iron and calcium deficiencies for female students. We should also educate students about dietary habits which contribute to obesity such as overeating and the intake of sweet foods.

This study was carried out to compare UCP2 polymorphism, dietary habits, and obesity index in normal and obese university students. The survey was carried out using self-questionnaires collected from the 126 normal and 60 obese university students. The results are summarized as follows. Breakfast was skipped in 43.7% of normal and 49.3% of obesity students and it appeared obese students eat faster than normal students. The percentage of weight control experience were 49.2 and 71.0 in the normal and obese students, respectively. Blood levels of lipid profiles(triglyceride, LDL cholesterol, and HDL cholesterol), hemoglobin, AST and ALT were anaylzed. In UCP2 genes, the frequency of deletion homozygote(DD) was 71.5%, heterozygote(DI) was 26.9% and insertion homozygote(II) was 1.6%. Plasma levels of triglyceride, total cholesterol, LDL cholesterol, and HDL cholesterol of normal students were 79.06, 172.25, 100.86 and 57.03 mg/dl, and those of obese students were 93.06, 173.22, 101.22 and 54.39 mg/dl, respectively. Blood parameters were in normal range in both group. Plasma triglyceride, total cholesterol and LDL cholesterol levels of obese students were higher than those of normal students. On the other hand, plasma HDL cholesterol levels of obese students were lower than those of normal students. Plasma levels of AST and ALT were in normal range in both group. However, AST and ALT levels of obese students were higher than that of normal students. Thus, it was recommended for them to have a nutritional education program to improve their dietary and living habits for obese students’health. Nutritional education program should also be organized practically and systematically.

Purpose : The purpose of this study was to investigated the dietary habits of students in order to identify risk groups according to their Body Mass Index (BMI), and to compare the eating behavior of students in the normal range (19${\le}$24) and those in risk groups (BMI${\le}$19, 24${\le}$27, BMI>27). Method : 1176 elementary school students, 850 middle school students and 672 high school students in Wonju City, were the participants The instrument for this study was a structured questionnaire that included demographic data as well as dietary habits, and the eating behavior instrument developed by Stunkard & Messick(1985) and revised by Kim & Kim (1997). Result : 1) As students moved up ingrade level their dietary habits became more irregular and the degree that students chewed food was reduced 2) As students moved up in grade level, a greater number of the student did not eat breakfast. The reasons given were that there were not enough time before classes started(40.4%) and a lack of appetite in the morning(10.6%) in high school students. 3) As for supper, from 67.8 to 81.9% of subjects reported having regular supper. However the rest of the subjects did not eat supper because of anorexia and fear of weight gain. 4) The results identified risk groups according to their BMI showed that for elementary school students, 55.9% were in the low weight group, 5.5% in the overweight group, and 0.9% in the obese group. For middle and high school students, 40.6% and 35.5% respectively were in the low weight group, 7.4% and 6.3% in the overweight group, and 4.1% and 2.5% the obese group. 5) Comparisons of the eating behavior of students in the normal weight group with that of those in the three risk groups showed that there significant differences in 'hunger' and cognitive restraint of eating' in elementary school students, and significant differences in 'cognitive restraint of eating' in middle and high school students. Conclusion : The results of this study show that management of diet in school health should be addressed from both the aspect of lack of nutrition and that of excess nutrition. In other words, good diet is as important for students in the low weight group as it is for those in the overweight and obese groups. The establishment of good dietary habits and eating behavior in students, by nurses and dieticians should be done by providing repeated diet education and involvement in diet counseling.

Objectives: The purpose of this study was to provide the nutritional education data of the fruit and vegetable eating habits and dietary fiber intake of male and female high school students in the Daegu area. Methods: A survey was conducted on 300 male/female students from four general high schools in the City of Daegu, and the survey included questions ongeneral characteristics, dietary habits, eating behavior patterns and dietary intake. A 24-hour recall method was used for the dietary intake, and the surveyed dietary intake information was analyzed using the Computer Aided Nutritional analysis program (CAN 3.0)--dietary fiber intake, in particular. The data was analyzed using the SPSS window 12.0 program. Results: The average ages of boys and girls were 16.8- and 15.6-years old, respectively. A classification based on BMI showed the following: the low-weight student group was comprised of 10.3% boys and 31.6% girls; the normal-weight group 68.4% boys and 67.5% girls; and the overweight group 21.3% boys and 0.9% girls, whereby showing a significant difference between boys and girls. Vegetable intake showed the following: the ratio of the response of 'taking it once a day' was more than 70%, which showed the low frequency of fruit intake; the ratio of 'taking it more than five times a week' was 53.0% for boys and 68.4% for girls, which showed a higher intake frequency for girls over boys; and the daily dietary fiber per 1,000kcal was 7.1g for boys and 8.2g for girls, whereby showing a significant difference between boys and girls. The meals that contributed most to dietary fiber intake were the school meals, whereas the dietary fiber intake rate through breakfast was the lowest among the three daily meals. The food groups that contributed to dietary fiber intake were vegetable, grains and flavoring matters for boys and vegetable, grains and fruits for girls. Conclusions: In order to increase the daily dietary intake for growing adolescents, who are in an important stage for building the foundation of health, it's recommended that, in addition to the supplement for insufficient dietary fiber through a regular breakfast consisting of high dietary fiber content foods, nutrition-related education about the effects of dietary fiber on the human body be conducted.

The purpose of this study was to investigate food preferences and dietary habits of university students in Kyungbuk province. We assessed anthropometric measurements, food preferences, and dietary habits of seventy nine male and sixty nine female students at K university. The results of this study were analyzed with $\chi$$^2$, t, and ANOVA test using SPSS package program. The percentages of students who were underweight, normal and overweight by body mass index (BMI) were 18.0, 22.1, and 27.7 for males, and 17.8, 21.7, and 28.7 for females, respectively. Preferences for noodles with bean sauce, bread (castella, red-bean bread), beef, pork, chicken, ham, garlic, milk soy bean milt carbonated drink ionic beverages, bun (fried, steamed), croquette, soju(alcohol) and tobacco were higher in males than females, but preferences for tangle, strawberry and orange were lower in males than females. Males did not skip meals compared to females, and ate more meat fat than females. Males exercised more frequently and longer than females. Eighty six point eight percent of females and 69.7% of males were dissatisfied with their weights, and females attempted the weight control more than males. Preferences for bibimbab(boiled rice with assorted mixtures), ionic beverages, and beer were shown higher in overweight males than in normal ones and preference for red fish, hamburger, and chocolate were higher in underweight females than overweight ones. Overweight females skipped meals more and ate more meat fats than normal weight ones. Normal weight males and underweight females were satisfied with their weight. The results of this study suggest that university students need more nutritional education, and modification of dietary habits based on food preference to prevent and treat obesity and to maintain their health.

The purpose of this study was to assess dietary variety by body mass index, waist circumference and exercise habits in 138 female university students residing in Bucheon and its adjacent area. Body mass index(BMI), waist circumference (WC) and exercise habits were assessed via a self reporting questionnaire, and a 3-day dietary recall survey was conducted by interviewing. Dietary variety was assessed by dietary diversity score(DDS), meal balance score(MBS), and dietary variety score(DVS). The average BMI, WC, DDS, MBS, and DVS were $20.7{\pm}2.59\;kg/m^2$, $69.3{\pm}5.03\;cm$, $3.87{\pm}0.57$, $7.27{\pm}1.48$, and $12.59{\pm}3.14$, respectively. The DDS for breakfast, lunch, supper and snack were $1.80{\pm}0.92$, $2.45{\pm}0.48$, $2.49{\pm}0.55$ and $0.53{\pm}0.52$, respectively. DDS, MBS, and DVS were not significantly correlated with BMI, WC and exercise habits. However, DDS for breakfast and supper were significantly higher(p<0.05) and lower(p<0.05) respectivly in subjects who exercised regularly compared to those who did not exercise regularly. And DDS for snack was significantly higher in subjects whose awareness of health status was good or somewhat compared to those whose that was bad(p<0.05). These findings suggest that nutritional education based on female university students' eating variety and regular exercise may be required to improved dietary variety.

This study was investigated to examine the dietary habits and satisfaction with a school lunch program for high school boys and girls. The survey was conducted on 416 students(208 boys and 208 girls) using questionnaire. Overall, 40.1% of the respondents reported that they skip breakfast, and more girls skipped breakfast than boys(p<0.05). The major reason for skipping meal was 'no enough time'(48.3%) and duration of meal appeared the highest ratio in '10~15 minutes'(51.7%) and boys having meal with 10 minutes were significantly higher than girls(p<0.001). When asked if they have an unbalanced diet, 58.8% responded "little bit do it but it depends on food". Vegetables were the foods most absent from an unbalanced diet. Additionally, 90% of all respondents takes a snack a day, and 21.5% of the respondents reported that snacks were the most preferable meals. In terms of a satisfaction with school meals, 70.6% of the respondents reported that they were "unsatisfied". Additionally, 43.5% of the students reported that they did not finish their soup. Moreover, 57.5% of the students reported that they were dissatisfied because that food was "not tasty". Based on the results of this study, the meal habits of the students were determined by various factors including gender. To ensure that boys and girls receive the proper nutrition, development of proper eating habits through school meals, nutrition education and a guidance during meal service should be achieved.

This study set out to investigate the effects of 16-week nutrition education and exercise intervention run by a public health center on the physical activities and dietary patterns of obese children at the before, after, and after one month point. After the program, the obese index of the obese children dropped by 5.9% from 38.4% to 32.5%. One month after the end of the program, their obese index increased by 1.4% to 33.9% (p < 0.001). The obese children's hours of walking of physical activities increased to 2.6 hours from 1.2 hours after the program and remained at the 2.6 hours range one month after the end of the program (p < 0.01). The total scores of their food habits increased to 10.4 points from 9.1 points after the program and 10.3 points one month after the end of the program with significant differences (p < 0.01). The total scores of their eating behavior made a significant increase to 6.5 points from 5.3 points after the program and then dropped to 5.9 points one month after the end of the program (p < 0.05). As for changes to their dietary pattern scores according to the obese index, only the food habits scores showed significant main effects of term (p < 0.05). According to these results, there is still a need to develop proper programs to help them increase regular exercise, improve their physical activities by cutting down time with TV, computer, Internet, and video games, and enhance their nutritional knowledge and to provide them with ongoing management and guidance until the improved food habits and eating behavior become part of their habits.
