This study was designed to examine fast food consumption, nutritional knowledge, food behavior and dietary intake of university students and to investigate if there were differences in these variables by fast food consumption. The questionnaire was administered to university students in Daejeon. Data(n=269) was analyzed using $x^2$-test and analysis of variance. Subjects were mostly female(62%) and freshmen or sophomores(86%). Based on the frequency of fast food consumption, subjects were categorized into non-users(27.9%), users(<2 times/week, 42%) and frequent users($\geq$2 times/week, 30.1%). Those who used fast foods(n=194) consumed the foods 7.5 times per month, on the average. Subjects scored 15.6 out of 20 on a nutritional knowledge scale, showing the moderate level of knowledge. When examined by fast food use, the nutritional knowledge score was 15.5 for non-users, 16.1 for users, and 15.0 for frequent-users(p<0.05). Only two items, regarding 'fat type(animal, plant) and health' and 'importance of having breakfast', were significantly different by fast food consumption, with user group and non-users scoring higher than frequent-users(p<0.05). Food behaviors, measured by 20 items, were not desirable, with mean scores of 51.5(possible score: 20-100). Subjects showed problems in eating meals regularly, eating a variety of foods, eating breakfast, and consumption of some food groups(vegetables, fruits, and proteins). Fast food non-users showed more desirable food behaviors than users or frequent-users, such as having processed foods (p<0.001) and eating-out less frequently(p<0.01). Dietary intake data showed that some nutrient intakes, including energy, calcium, iron, zinc and folic acid were less than 75% of the RDA. Index of nutritional quality(INQ) was adequate except for calcium and zinc. Compared to non-users or user group, frequent-users of fast foods consumed higher amounts of lipids(p<0.05), and had lower INQ for calcium(p<0.01). This study described the status of fast food consumption, nutritional knowledge, food behavior of university students, and provided some baseline data for planning nutrition education for university students.

The purpose of this study was to investigate the effect of nutritional education on the knowledge and the practice & Perception of diet therapy, and on the level of FBG and HBAlc. The subjects were selected among the patients treated in the Inha University Hospital from June of 1996 until April of 1998. Educated group consisted of 20 patients who visited the diet-counseling department as a part of diabetic treatment. Non-educated group consisted of 20 patients who visited the diet-counseling department ignoring doctors prescription purpose. The knowledge and the practice & perception of diet therapy drinking & smoking habits, regular exercise, and general characteristics including family history were analyzed by questionnaires. FBG and HbAlc were measured before and 4 months after the treatment. The results were as follows : Both groups were composed of 12(60%) male and 8(40%) female respectively. The mean age of subjects was 51.4 years in educated group and 51.9 tears in non-educated group. The duration and %IBW were 5.9 years and 109.8 % in educated group and 5.5 years and 111% non-educated group respectively. There were no significant differences in drinking & smoking habits and regular exercise between groups. The diet therapy knowledge score was significantly higher in educated group(p<0.001, 5.8$\pm$2.3/10.0 vs 3.4$\pm$2.0/10.0). The diet therapy practice & perception score was also significantly higher in educated group(p<0.001, 5.6$\pm$2.3/10.0 vs 2.8$\pm$2.2/10.0). Levels of FBG and HbAlc in both group were reduced at 4 month after the treatment(-74.2 mg/dl and -1.4% in educated group vs -58.7 mg/dl and -2.0% in non-educated group). However, the reduced amounts of them were not significantly different. Therefore, nutritional education seems to be very important in improving the knowledge and the practice & perception of the diet therapy. However, it appears no direct influence in reducing FBG and HbAlc levels. Further studies on diabetic management by using more efficient, consecutive and intensive nutritional education methods are needed. (Korean J Nutrition 34(1):69-78, 2001)

Purpose: This study was done to identify the relationships between body mass index, nutritional knowledge and the health promotion behavior of nursing students. Methods: Participants consisted of the entire 330 members of the student body of a Korean nursing college. Variables included body mass index, nutritional knowledge and health promotion behavior as well as demographic variables. Data was analyzed by frequencies, ANOVA and Pearson's correlation with the SPSS/Win 21.0 program. Results: The mean score for body mass index was $20.23kg/m^2$ for nutritional knowledge, $14.27{\pm}3.07$ on a total 20-point scale, and for health promotion behavior, $3.03{\pm}0.34$ on a 4-point scale. Nutrition knowledge positively correlated with health promotion behavior (r=.368, p<.001). Health promotion behavior positively correlated with underweightness (r=.120, p=.005), normal weight (r=.212, p<.001), negatively correlated to overweightness (r=-.351, p<.001), and obesity (r=-.413, p<.001). Nutrition knowledge positively correlated to underweightness (r=.155, p=.005), and normal weight (r=.346, p<.001), negatively correlated to overweightness (r=-.548, p<.001), and obesity (r=-.342, p<.001). Conclusion: In order to enhance the effective health promotion behavior of nursing students, it is important to actively intervene to improve body weight control behavior and nutritional knowledge. Therefore, developing an educational program for improving nutritional knowledge and body weight control behavior of nursing students is recommended.

This study examined students' nutritional knowledge on fat, the quantity of fat in food, and their dietary practices with regard to fat. The subjects were junior & senior students majoring in food and nutrition(n=188), Korean Oriental medicine(n=236), and physical education(n=13), respectively. The score for nutritional knowledge of fat was $8.48{\pm}0.15$ for food & nutrition majors, $6.73{\pm}0.14$ for Korean Oriental majors, and $4.97{\pm}0.72$ for physical education majors, with significant differences between groups(p<0.0l). The correct answer percentages were 65%, 52%, and 38% respectively, out of a total 13 items, and significant differences were observed between the majors. The score for knowledge on the quantity of fat in food was $5.40{\pm}01.3$ for food & nutrition majors, $5.40{\pm}0.10$ for Korean Oriental medicine majors, and $4.53{\pm}0.15$ for physical education majors, with significant differences between the groups. The correct answer percentages were 60%, 60%, and 50% respectively. The number of correct answers was significantly different in 7 out of a total of 9 food items depending on major. For dietary practices regarding fat there were significant differences in 10 out of a total of 12 items depending on major. The total scores were $34.02{\pm}0.45$, $33.04{\pm}0.44$, and $31.19{\pm}0.72$, respectively, showing no significant differences between the groups. Regarding the scores on nutritional knowledge about fat, the students majoring in food & nutrition received the highest scores, and on knowledge about the quantity of fat in food, students majoring in food & nutrition and Korean Oriental medicine attained higher scares than the students majoring in physical education. However, there were no significant differences between the groups regarding their dietary practices toward fat.

This study was to evaluate the anthropometry, dietary attitudes and the other factors of 201 children in day-care centers according to their parents' income levels. The evaluation was conducted using anthropometric measurements such as height, weight, skinfold thickness, blood pressure, and questionnaire survey which was completed by the children's mothers. The results are summarized as follows: Overall growth of children was normal according to Korean standard. There were no significant differences in anthropometry according to the income levels. The scores of eating habits of children were different significantly according to income levels. That is, the score was the lowest in the low-income group. Children generally prefer one-dish meal or snacks, while the preference levels of kimchi, seasoned vegetable and beans broiled in soysauce were lower than those cf other foods. In the questions to know mothers' nutrition knowledge, we could see that they didn't know well about protein, breast-feeding, weaning and balance in nutrients. Nutrition knowledge score of mothers was significantly lower in the low income group, which shows close relationship with low-score eating habits of their children. The score of nutrition knowledge was affected by the mother's education level. The higher the mother's nutrition knowledge and education level, the better children's eating habits. These findings emphasize the planning and application of nutrition education programs for mothers especially in the low income group.

The purpose of this study was to evaluate the nutritional knowledge and dietary behaviors of middle school students according to their mother's employment status. Of all 453 subjects, 52.1% were boys, and 67.5% of the mothers were employed. The total score of nutritional knowledge was 8.0 out of 10 for students with a non-working mom and 7.7 for those with a working mom, showing no significant difference. Among the 20 nutritional knowledge questions, correct answer rates for "lots of fruits may be eaten because of not gaining weight" (72.6% vs. 81.6%, p<0.05) and "eating raw carrots is better than eating fried ones with oil" (34.6% vs. 44.9%, p<0.05) were significantly higher in students with a working mom. The regularity of meals showed a significant difference according to the mother's employment, indicating that responses of "very regular" (62.4% vs. 72.1%) were high among students with a non-working mom and responses of "skipping breakfast" (31.4% vs. 19.7%) were higher in students with a working mom (p<0.05). The number of snacks a day was also significantly different according to the mother's employment, showing that 12.8% of the students with a working mom and only 3.4% of them with a non-working mom did not eat snacks at all (p<0.05). These results reveal no significant difference in middle school students' nutritional knowledge according to their mother's employment status; however, the students whose mother had a job were more likely to have more undesirable dietary behaviors such as irregular meals and snacking.

Nutrient supplements are often used by athletes as ergogenic aids. This study was done to investigate the use of nutrient supplements, nutritional knowledge and nutrient intakes of athletes. Subjects of this survey consisted of 195 national team athletes. The prevalence of nutrient supplement use among all subjects was 30.3%, and the frequency of use, by decreasing order, was weight lifting, taekwondo and badminton athletes. Sport drinks were the type of nutrition supplement used most frequently and vitamin C was the second one. Major reasons for nutrient supplement use were to improve training performance and to recover from fatigue, to supplement fluid and to control weight. The average score of nutritional knowledge was $19.9\pm{2.5}$ for nutrient supplement users, and $19.8\pm{3.6}$ for nutrient supplement nonusers. Intakes of protein, calcium and niacin of the user were higher than those of the nonuser. This information provided by this study can help sport nutritionists identify nutrient supplement most often consumed by national elite athletes and can aid counselors as they guide athletes towards more healthful nutrition practices.

This study was conducted to evaluate the nutritional status of the elderly women, who attended the Health Promotion Program of the Seogu Health Center in Daegu. The study subjects were 158 elderly women in an urban community. The general characteristics, dietary behavior (nutritional knowledge, nutritional attitudes and dietary habits), food and nutrient intake were surveyed by an individual interview. The average age of the study subjects was 70.9 $\pm$ 2.3 years of the subject group 79.1% ranged in age from 65 to 74 years and 20.9% were over 75 years. Their average score for nutritional knowledge, nutritional attitudes and dietary habits was 7.3 (total mark of 10), 7.2 (total mark of 10) and 9.1 (total mark of 22) respectively. Specifically, the level of the dietary habits of the study subjects was very low. In relation to food group intake of the study subjects according to age, their food intake was low. The total, plant. and animal food intake were 1078.9 g, 954.4 g (88.5%), and 244.4 g (11.5%), respectively. The mean daily energy intake and nutrient intake according to percentage of the Korean RDA were higher in the from 65 to 74 year group than in those people over 75 years. The average calories and the mean percentage of nutrient intake, except for vitamin C and phosphorus. were below 75% of the Korean RDA. It seems that the nutrient intake was very low. The mean nutrient adequacy ratio (MAR) was 0.59. Nutritional status of age over 75 years old was significantly lower than that of 6574 years old group (Mar ＝ 0.60 VS 0.54, p ＜ 0.05) The correlation coefficients between their dietary behavior (nutritional knowledge, nutritional attitudes, dietary habit) and their mean nutrient adequacy ratio (MAR) showed significant linear relations. In conclusion, if nutritional education is to affect the dietary behavior of elderly women, it should be included in a Program to Promote their nutrition and health status.

This study evaluated the effect of nutritional improvement of 0~5 year children of financially poor families after nutrition supplement of children and nutrition education in parents/guardians. The subject selected among applicants for low-income family financing of the government included 198 children (0~12 months:92, 1~5 years:106), and the average ages were 5.3 months and 2.4 years respectively. Food that includes each nutrient factor was provided to the subject for six months. Nutrition education was performed in two ways, through class and private education, once a month for both. Nutritional improvement was evaluated by body measurement and anemia prevalence rate. As to the survey on breast-feeding, complete breast-feeding accounted for 58.7%, weaning food 27.3%, and combined feeding 14.1% respectively, which shows that breast-feeding accounted for the largest percentage. The education program improved knowledge and attitude of the parents/guardians, which brings in positive effects on growth of children as well. The nutrition knowledge score was improved after nutrition education in 0~12 month children $(8.5\pm1.75\;to\;8.9\pm1.69)$ and 1~5 year children $(7.3\pm1.39\;to\;7.8\pm1.30)$. The nutrition attitude score was significantly improved in 0~12month children $(52.0\pm6.99$ to $53.5\pm5.21$, p < 0.001) and 1~5year children ($45.1\pm7.30$ to $49.0\pm5.96$, p < 0.001). In evaluation on nutritional improvement based on body measurements, it turned out that the wasting was reduced as for children in consideration of the height and weight according to the subject's age. The concentration of hemoglobin after the nutrient treatment for six months was significantly improved, and the anemia prevalence rate as well was reduced from 40.6% to 13.5%, which indicates the significant improvement. Based on the findings above, it turned out that providing quality food to children and nutrition education to the parents/guardians poorly fed in low-income families improved knowledge and attitude of the guardians and prevents anemia and improves growth, which brings in positive effects on growth of children. In the results regarding attitude and knowledge on nutrient/dietary life; however, the improvement level was relatively low when the extent before the education was too small, which indicates the need to revise and complement the contents and methods. In addition, as shown in the result of body measurement, long-term and consistent investigation is necessary since it is difficult to judge the effect on growth only based on short-term nutrient supplement.

Nutrition education in elementary school is confronted with the present problem, as a legal basis about obligation of nutrition education in school was clarified. Moreover, it's also important for providing evidence based scientific resources to make a study of evaluating the education effectiveness. Most studies of the nutrition education effectiveness have evaluated the changing dietary attitude and nutritional knowledge score before and after the nutrition education, and suggested the effectiveness of intervention as changing between pre- and post-treatment. Nutrition education, however, purposing long-term changes, follow-up evaluation process about the learned attitude and knowledge of nutrition education were requested. For these reasons, this study attempted to fulfilled standardized nutrition education program which use "Na Story and Food World" and "Na Story for Me", a textbook for the 1st-3rd grade and 4th-6th grade designed by KFDA, and analyzed the changes about the effectiveness of nutrition education happened over a period of time. In this study, each student was assessed their dietary attitude and nutritional knowledge by four periods, before the education, right after the education, after 3 months, and after 6 months. As a result, an average score of nutritional knowledge before the education, $70.08{\pm}17.91$, were changed significantly higher right after the education to $85.69{\pm}15.05$ (p < 0.001), but it lowered to $84{\pm}15.56$ after 3 month. After the nutrition education, students in all grades had positive dietary attitude to Na reduction (p < 0.001). However, the healthy eating attitude about Na reduction had been unable to maintain after 3 and 6 months. Therefore, the systematic reeducated program in elementary school was positively necessary to reinforce children's learning and cognitive skills to maintain healthy eating knowledge and attitude toward Na reduction.
