The purpose of this study was to investigate the eating habits and eating behaviors, nutrition knowledge of students in 4, 5 and 6th graders of elementary school in Jeonju Area. The subjects for questionnaire were 2,568 elementary school students (boys 1,364, girls 1,204). The results were analyzed by SPSS program, and were as follows. In anthropometric data, there were significant differences between boys and girls. In eating habits and eating behaviors, there were significant differences in the rate of 'Hasty eating habit(p<0.01)', 'Most heavy meal(p<0.01)', 'Eating when receive stress(p<0.05)', and 'Frequency of snack eating per day(p<0.01)' between boys and girls. In total scores of nutrition knowledge, there were significant differences between boys and girls. In nutrition knowledge, there were significant differences in the rate of 'Carbohydrate and fat give heat and force.(p<0.001)', 'Carbohydrate is nutrient that make muscle and blood of our body.(p<0.01)', 'Overeating of carbohydrate does not contribute gain of weight. (p<0.05)', To intake vitamin, it is good to eat fresh fruit and vegetable.(p<0.01)', 'Calcium deficiency is leading to anemia.(p<0.001)' between boys and girls. In conclusion, systematical educational programs need to be developed at elementary school. These should include information about achieving a balanced diet, good eating habit and behavior, meal management and Korean dietary culture. Also, nutritional education at home must be emphasized.

This study was designed to estimate mean daily iron intake and its bioavailabi- lity and to assess nutrition knowledge for 144 pregnant women in the last trimester. Serum ferritin concentration was analyzed to estimate their iron stores. Dietary intakes of iron(heme iron and nonheme iron), the amounts of MPF(meat, poultry and fish) and ascorbic acid were assessed by modified 24-hr recall method. The food frequency questionnaire was used to assess subjects usual food consumption patterns. The mean value of serum ferritin was $21.3\pm{15.2ng/ml}$ and 26.4% of the pregnant women had a serum ferritin level <12ng/ml(i.e. depleted iron stores). The mean daily intake of total orin in the pregnant women was 56.5%(17.0mg) of RDA and heme iron intake was 0.94mg which was 5.5% of total iron intake. Total absorbable iron calculated by the method of Monsen was 2.41mg and bioavailability of dietary iron was 2.41%. Food frequency test score of meats group was positively correlated(r=0.443) with the bioaavailability of dietary iron. The mean score on the nutrition knowledge test of subjects was 12.76(out of a possible 20 points). These results indicate that the nutritional iron status may be improved by increasing either the amount of iron in the diet or its availability.

This study was conducted using a self boarding questionnaire survey to investigate body image perception, dietary habits and nutrient intakes according to interest level in health of female university students in Masan area (n=302). The subjects were divided into 2 groups according to interest level in health ('High' group, n=101, 'Low' group, n=201). Body image according to BMI was significantly different regardless of interest level in health (p<0.001). The answer percentage indicated that the purpose of weight control is health, regular use of the scale, and regular exercise were significantly higher in the high group (p<0.05). Nutrient knowledge score (p<0.01) and food frequency score (p<0.001) were significantly higher in the high group (p<0.01). There were no significant differences in nutrient intake, but intake, NAR and INQ of vitamin C were significantly higher in the high group (p<0.001). Nutrition knowledge score (p<0.01), food intake frequency score (p<0.01), and INQ and NAR of vitamin C (p<0.01) were positively correlated with the interest level in health. These results will be useful as a basis for the development of effective nutrition education programs in order to increase interest level in health and apply well in real life what have learned through the correct nutrition knowledge.

The study evaluated the effectiveness of intervention for male adolescent smokers by making an assessment in terms of changes in food habits, nutrition knowledge, plasma catalase, superoxide dismutase(SOD), glutathione peroxidase peroxidase(GSH-px) activities and thiobarbituric acid reactive substance(TBARS) after Vit C supplementation and nutrition education. The subjects, male adolescent smokers, were assigned into four groups : Control group(19 students), education(Educ.) group(19 students), Vit C supplementation (suppl) group(19 students), and Educ. + Vit C suppl. group(19 students). The Educ. group and Educ. + Vit C suppl. group received nutrition education once a week for 2 weeks. The Vit C suppl. group Educ. + Vit C suppl. group received 500 mg ascorbic acid for 35 days. All data were collected before intervention and after intervention. Nutrition knowledge of those who received education increased, and the frequency of fruit and yellow-green vegetable consumption also increased. Plasma antioxidant enzyme activities were not different except for the SOD activity in the Educ. + Vit C suppl. group, which was significantly increased. The plasma ceruloplasmin level of groups that received Vit C supplementation was reduced more than any other groups, and the specific ceruloplasmin ferroxidase activity of groups that received Vit C supplementation was elevated more than other groups. These intervention programs had an impact on food habits, nutrition knowledge, plasma antioxidant enzyme activities, and plasma TBARS in male adolescent smokers. Various nutrition education programs must be implemented for adolescent smokers, and further studied are needed regarding sorts and amount of antioxidant nutrients and supplementation duration.

This study was carried out to evaluate the effects on elementary school children of Internet-based nutrition education programs. The subjects consisted of 80 boys and girls (book-loaming group : 42, Internet-based teaming group : 38) in the 5th grade of elementary school. The results were as follows : The evaluation of Internet-based education programs by Internet-teaming group showed above average in all domains. As the favorite and wholesome menu chose‘nutrition kingdom’(52.6%) made of animation. The educational effect of this program was evaluated by comparing the methods of the Internet-learning group with those of the book-learning group. For effect-evaluation were measured the degree of nutrition knowledge and diversity score of dietary intake from before and after education. Before undertaking the program, there was no significant difference between the two groups in terms of their nutrition knowledge. However, the nutrition knowledge of the Internet-based teaming group after the program had increased significantly (p < 0.01) compared to the book-learning group. There was no significant difference between the two groups in terms of the diversity of dietary intake before the start of the program, but upon its completion, the Internet-based learning group showed a significant increase compared to the book-loaming group (p < 0.05). This suggests that Internet-based educational programs could be effective in drawing the interest and boosting the concentration levels of schoolchildren. In conclusion, Internet-based nutrition education shows the potential to be an effective alternative education method. (Korean J Nutrition 36(5): 500∼507, 2003)

Parents play an important role in the development of their children's nutritional knowledge, attitude and practice (KAP). This study was conducted to investigate and assess the nutrition KAP status related to prevention of childhood obesity for parents of preschool children. 1828 subjects were selected cluster-randomly from 6 kindergartens in the urban of Chengdu, China and were surveyed by questionnaire. The results showed that the rate above $80\%$ of total score were $64.3\%(K),\;89.6\%(A),\;19.5\%(P)$ respectively. The nutrition KAP score of subjects was influenced by their education, gender and age. K, A and P scores were positively correlated with each other. The most expected approach obtained nutritional information for subjects was from newspaper, magazines, lectures and TV. It is concluded that the parents of preschool children in Chengdu indicated the limited nutrition knowledge, imperfect nutrition practice and better nutrition attitude. It is suggested that more nutritional education programs on childhood obesity prevention should be given mainly by newspapers, magazines and lectures in this population.

Television is a powerful and persuasive teacher. It has the potential to influence perceptions, knowledge, beliefs, and behaviors, thus nutritionists need to be aware of the nutrition-related information (NRI) in television programming and the effect this information has on viewers. The purpose of this article was to review research published in peer-reviewed journals between 1988 and 2003 that examined the NRI embedded in American television programming, which is exported to over 125 nations, and its impact on nutrition knowledge, attitudes, and/or behaviors. This review revealed that, for the past 15 years, NRI was commonly included in both television advertisements and shows. Advertised foods were mainly high in fat, sodium, and/or sugar. In addition, the NRI embedded in food advertisements tended to be misleading or inaccurate. Prime-time television shows included numerous NRI containing scenes every hour, with situation comedies having the most and real-life re-enactment shows the least. Overall, low nutrient density foods accounted for approximately 40 percent or more of all food references on prime-time television shows. In television shows, foods were mostly consumed as snacks rather than meals and children often ate more nutritious foods than adults. Although relatively few studies have examined the impact of television programming on viewers, those that do exist indicate that as children watch more television, nutrition knowledge and understanding declines while misconceptions about nutrition increase. Advertising influences children's food purchase requests and subsequent purchases by adults, with the most requested and purchased foods being high in sugar, fat, and/or salt foods. Existing research indicates that television must be acknowledged as a major source of NRI and a potentially powerful influence on dietary practices.

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.
