This study was designed to evaluate Saturday nutrition classes for obese elementary students in Chungnam Province. Obesity index, nutrient intake, nutrition knowledge, nutrition attitude, and self-satisfaction of 36 obese elementary students were compared before and after attending nutrition classes every other Saturday for 3 months. The average age, height, weight, body fat, % body fat, and obesity index were 11.9 years, 145.5 cm, 53.3 kg, 24.5 kg, 45.7%, and 32.4%, respectively. Most of the subjects(94.5%) viewed themselves as fat. Sixty-three percent of children were discontent with their body-image. All answered that they have experience with weight control. The major methods of weight control were exercise and reduction of snacks. The mean serum cholesterol, blood glucose, GOT/GPT, and hemoglobin were 177.4 mg/dL, 90.4 mg/dL, 25.8/25.5 IU/L, 14.5 g/dL, respectively. After attending nutrition classes, the daily intakes of energy, plant protein, plant fat, carbohydrate, crude fiber, and cholesterol increased significantly. The scores for nutrition knowledge, nutrition attitude, and self-satisfaction also increased after nutrition classes, but there were no significant differences. Percent body fat decreased significantly after nutrition classes. In conclusion, nutrition education for elementary students is effective for the prevention and control of obesity. Further research is needed to develop a systematic program of nutrition education for obese children.

This study aims to identify the dietary patterns relevant to obesity of Korean women among low income classes. Adults 20-64 years were used as study subjects from the data of 2005 Korea National Health and Nutrition Examination Survey. We compared obese and normal-weight women in terms of their nutrients intake, diet quality and food patterns. Diet quality was assessed by using the Nutritional Adequacy Ratio (NAR) and Index of Nutritional Quality (INQ). Our results showed higher prevalence of obesity among lower socioeconomic status women. In men, there were no significant associations with socioeconomic status and prevalence of obesity. Higher risk of nutritional inadequacy was observed among obese women compared to normal weight women. Obese women showed significantly lower INQ for nutrients such as Ca, Fe, Vitamin A, Thiamin, Riboflavin and Vitamin C compared to other women. They consumed significantly higher amount of rice (p < 0.05) and lower amount of vegetables (p < 0.01). By contrast, obese men from low income classes showed higher intake of those nutrients. Obese men also consumed significantly higher amount of meats than normal weight men. Therefore, this study suggests that gender-specific approaches based on economic situation should be considered in developing the intervention program for managing obesity for low income classes.

BACKGROUND/OBJECTIVES: Filipino children aged 6-10 yrs are consuming poor quantities and quality of food based on the 2013 Philippine National Nutrition Survey. During these years healthy eating habits must be formed through family influence. Within this background, a complete package of nutrition intervention-feeding and nutrition classes, was pilot tested in selected schools to determine 1) changes in nutrition attitude and behavior and 2) food intake of schoolchildren after the intervention. SUBJECTS/METHODS: A quasi-experimental design was used in the study. School children aged 7-9 yrs enrolled in selected Philippine public elementary schools and their mothers/caregivers were the study participants. Profile and socio-demographic data were collected from each participant at baseline. The nutrition behavior and food intake of children were determined using the modified Child and Diet Evaluation Tool (CADET) and the 24-h food recall form, respectively. Data were analyzed using Stata version 15. RESULTS: No significant differences in characteristics were found among the 339 child-mother pairs in the 4 study groups. The modified CADET recorded improved mean attitude scores of children ranging from 22 to 24 points at endline in the group receiving both lunch feeding and nutrition education classes (group 3). The perceived better behavior of children was reported by their mothers in terms of increased intake of milk and vegetables and decreased consumption of sugar. These improvements were supported by the actual food intake of children obtained from the 24-h food recall. CONCLUSIONS: Family involvement, particularly of mothers/caregivers, appeared to be an important factor in shaping the children's eating behavior. An intervention package with lunch feeding and nutrition classes resulted in a substantial improvement in children's behavior and actual food intake with increased levels of vegetables and milk while lowering sugar consumption. The adoption of the intervention package in public elementary schools should therefore be pursued.

This report was the result of Food and Nutrition Intake Survey of 210 adults of 43 rural households in 7 villages located on Kyung Nam, Korea. It was intended to provide baseline information on the nutrintional status and inequality, the change of food consumption pattern of different rural socioeconomic classes. The survey results were as follows; 1. All the nutrient intakes(except Ca) were above RDA in landlord classes, but those were extremely poor in tenancy and rural laborer classes. Ca was the most deficient nutrient in all classes. 'Vitamin A' was deficient in most of the classes. 2. In per capita food consumption expenditure, the highest was in landlord class, next capitalist farmer and middle class farmer, the lowest were rural laborer and tenancy. There were highest consumption of vegetables and fish in landlord class, and milks and oils in capitalist farmer. The consumption of rice fruits, meats, eggs, and seasoning were relatively proportionated to the income. 3. In the change of food consumption, the most increased items were beverages and meats in capitalist farmer, fish and fruits in landlord, rice in the other classes. 4. In the correlation with food consumption, education level showed the highest correlation with meats, oils, and in contrast, land sire showed the highest correlation with cereals. Engel's coefficient was positively correlated to cereals, but negatively correlated to fish and meats.

Objectives: The purpose of this study was to explore the effectiveness of the STEAM (Science, Technology, Engineering, Arts, and Mathematics) education program on the use of specific food groups in improving nutrition-related knowledge and attitude, dietary behavior, creative problem solving, and STEAM attitude. Methods: We selected two classes at a kindergarten in Jeollabuk-do, South Korea. A total of 44 kindergarteners from the two classrooms participated in this study. The experimental group and the control group were formed with 22 students each. The experimental group attended 11 STEAM classes on the use of the grain, fruit, and milk food groups. First, we performed the paired t-test to examine changes from pre-to-post classes for both groups. Then, we used ANCOVA to compare post-test scores between the experimental and control groups with the adjustment of pre-test scores. Results: The results demonstrate that the STEAM education program on the use of the food groups significantly improved (1) nutrition-related knowledge and attitude, and dietary behavior (P < 0.001), (2) creative problem solving (P < 0.001), and (3) STEAM attitude (P < 0.001) in the intervention group when compared with the control group. Conclusions: The STEAM education program on the use of food groups is effective in enhancing nutrition knowledge and attitude, dietary behavior, creative problem solving, and STEAM attitudes among kindergarten students.

The purpose of this study was to investigate teacher's perceptions about the nutrition education of elementary schools. A total of 226 elementary school teachers within Changwon and Milyang city participated in this study. The results of this study were as follows. 90.8% of the teachers responded that nutrition education is necessaty in the elementary schools, and positive responses in the Milyang urban area were higher than that of the Changwon rural area(p＜0.001). The main reason for the necessity of nutrition education was for proper growth and good table manners and the Milyang urban city was significantly higher than three other classes in ‘for proper growth’(p＜0.05). The starting period for nutrition education was supported by 72.1% of the teachers as beging when the children are in kindergarten, proving that this early nutrition education is supported. Especially in the Changwon urban support was higher than in the three other classes(p＜0.01). The perceptions about a suitable person to teach nutrition indicated parents(39.6%), dietitions(35.5%), class teachers(24.9%), and the beliefs about nutrition specialists or dietitions was very low. 53.6% of the teachers responded that they would not teach nutrition education themselves and the main reason for this was that believed the teacher's work would be too hard(32.0%), lack of nutrition knowledge(29.4%), and that such courses should be taught courses by specialists(29.4%). However, 51.6% of the teachers disagreed with having a separate course for nutrition education. Proper eating habits(62.7%) and growth and nutrition(28.6%) were the main categories within nutrition education. The teacher recognized that elementary students' nutrition problem is to eat too much processed and instant foods(39.1%), deviated foods(36.9%), and lack of table manners(19.4%). The most effect method was to link the subject matter with the parents(38.7%), use of audio visuals and education materials(28.3%), and need of nutrition education teachers(10.1%) was low.

This study was conducted to gather the baseline data on realities of experimental-practice and opinions toward spot-practice, and to examine how to cope with the problems raised at the Department of Food and Nutrition of Junior Technical College in Korea. Questionnaires were gathered from 42 chairmans of the Department of Food and Nutrition and 140 Present dieticians worked in Seoul, Bucheon am Seongnam area. The results are as follows, First, as a whole, each college had 2~3 experimental laboratory (Lab), in which Cooking Science Lab. Chemistry Lab and Microbiology Lab were occurred at higher frequency as Lab's name. Second, the numbers per experimental-practice class were more than 40 at most colleges. 85% of Present dieticians have answered to feel too much numbers per the class during their college days, whereas professors' opinions toward the numbers per class were suitable at 20~30 persons per class. Third, professors' opinion toward the adquate ratio of the theory subject classes to experimental subject classes was suitable at 60 : 40. Dieticians answered to take the theory subject classes partly or mostly on behalf of the experimental-practice classes. Fourth, the main reasons which inhibited normal experimental-practice class were the class for emphasis on examination, the shortage of experiment budget, the excess of class members, the shortage of experimental Lab Also, this results showed same propensity to present dieticians' opinion toward the same question above. Fifth, among the experimenta1-practice subjects established at the Department of Food and Nutrition, Diet Therapy Lab was highest frequency class emphasized on theory followed by Nutrition Counselling Lab, Food Processing and Storage Lab, Food Hygiene Lab and Food Microbiology Lab in that order. Here, Basic Chemistry Lab, Biochemistry Lab, Food Microbiology Lab were pointed as subjects far from the present task of dieticians. Sixth, Department of Food and Nutrition, as a whole, has conferred with spot-practice arrangement About 50% (all who want to join spot-practice) of second year students took part in spot-practice. In the other way, all colleges except for 2 colleges didn't give the credit for the spot-practice system. Seventh, according to the on analysis on spot-practice places, manufacturing company was at highest frequcney followed by hospitals, elementary school having group feeding system in that order. Especially, 16.7% (5 colleges) of the total colleges sent the students to the research institute related to food industry for spot-practice experience. Eighth, Professors' opinions toward the spot-practice time and period were preferable on summer vacation of second year and for 1~2 weeks, respectively. On the contrary, 74 dieticians answered to the adquate period as for 4 weeks. Ninth, 86 dieticians of the total 140 answered to complete the spot-practice during their college days, which helps the present task of them. Lacks of spot-practice program, Lacks of comprehension of upper personals and lacks of group feeding equipments ranks higher as difficulties in spot-practice management.

This study empirically examined the actual level of elementary school children's knowledge of nutrition and the extent of current nutrition education for the children through the use of textbooks. Two or three classes were sampled from each of six schools, respectively, in Gangneung; of the 562 questionnaires that were distributed, 537 were returned and used for analysis. Respondents were all sixth-graders, on average boys and girls were 153.02$\pm$8.19㎝ and 152.79$\pm$7.15㎝ in height and 45.27$\pm$10.32㎏ and 43.33$\pm$7.46㎏ in weight, respectively, which was consistent with others' research. Most children had two siblings and a working mother, considered that they were well off, and their mother prepared meals. Children regularly had breakfast and dinner, although more children had dinner than breakfast. As a whole, their knowledge of the main nutrients contained in foods was lower than their general knowledge of nutrition. There were significant differences in knowledge of the main nutrients contained in foods, with girls showing more knowledge than boys (p<0.01). Most of them learned about nutrition at school, followed by home. At school, Practical Technology classes taught them the most about nutrition. Although Physical Education classes were expected to teach about nutrition in a quantitative way, they accounted for just 4.7% of the overall knowledge. As for the children's understanding of nutrition education through use of a textbook at school, just 19% of the students gained a very good understanding. As for interest in nutrition education at school, 22.2% of the students had no interest, while girls were more likely to have their interest in nutrition education at school affected by knowledge of nutrition than boys. For both boys and girls, the most desired method of education was cooking practice. More research across subjects is necessary so that nutrition education concentrated on the curriculum for fifth-graders can be provided by stages from the lower grades. Since cooking practice or games were preferred, it is necessary to develop nutrition education methods to incite active interest rather than passive education.

The purpose of this study was to examine the dietary habits and nutrient intakes of school-aged children participating in extracurricular classes, to with regards to class schedule. Three-hundred and two students from Seoul were selected and classified into two groups. One group attended extracurricular classes less than 12.43 hours per week, which was determined as the average number of hours per week(AELT, n=147). The other group attended extracurricular classes more than 12.43 hours per week(AEMT, n=155). The average student age in both the AELT and AEMT groups was 11.9 years, respectively. In terms of height and weight, there were no significant differences between the two groups. AELT received significantly more hours of sleep than AEMT(p<0.01), and there were significantly more responses with regard to lack of sleep in the AEMT group than in the AELT group(p<0.05). In a survey on 17 clinical symptoms regarding health, the AEMT group had significantly higher response rates than the AELT group in the following sections: no appetite (p<0.001), dizziness(p<0.001), headache(p<0.01), tiredness(p<0.01), cold symptoms(p<0.05), and sore eyes(p<0.05). Meal time irregularity was significantly higher than AEMT than in AELT(p<0.05). Approximately 50% of the subjects were picky eaters, and 40% and 20% skipped breakfast or dinner, respectively. The average energy intakes for AELT and AEMT were 2122.2 kcal and 2061.5 kcal, respectively, and there was no significant difference between the two groups. AEMT consumed significantly lower quantities of protein, animal fat, vitamin $B_6$, calcium, and phosphorus(each p<0.05) as compared to the AELT group. Beverage intake was significantly higher in AEMT than AELT(p<0.05). The number of hours in extracurricular classes showed a significant negative correlation with the intakes of protein, animal protein, animal fat, vitamin $B_6$, folate, calcium, plant calcium and phosphorus(each p<0.05). The number of hours in extracurricular classes also showed a significant negative correlation with soy foods intake(p<0.05). These results suggest that continuous and systematic nutritional education should be performed in order to prevent and improve the unbalanced diets and problematic of dietary habits that may result in students due to attendance in extracurricular classes.

In order to investigate the differences of nutrient intakes by the economic status and different age groups and to identify the nutritional risk group and its specific nutrition problem, 2001 Korean National Health and Nutrition Survey were analyzed. The subject's numbers of 9,391 were classified into four classes such as low (14.2%), medium (37.2%), high (26.0%), and high above (22.6%) on the basis of the family monthly income and the 2001 Korean minimum cost of living according to the family size. Mean intakes of energy and all nutrients assessed by the RDAs, lipid-energy %, and MAR were increased as the economic status were going up. Na intake expressed per 1,000kcal was in reverse. Nearly a half(45.5%) of the low-income people seemed to take nutritionally inadequate diet in consideration with MAR values. Deficiencies of iron and even energy in the toddlers (1 to 2 years) of low-income class were of great concern. Adolescent age group has been observed that their calcium and iron intakes, and possibly energy, were appeared to be the most deficient among all the age groups regardless of the economic status. For the elderly in all the economic status except high-above class, calcium, vitamin A, and riboflavin were commonly deficient nutrients. Calcium deficiency was appeared throughout nearly all the ages except toddlers and all the economic classes. Even in the high-above class 57.3% took insufficient amount of calcium.
