The purpose of this study was to investigate the effects of obesity on the satisfaction with school lunches and school lunch leftovers of elementary school children in the Kyeonggi area. The study was carried out on 235 children(male : 111, female :124) in December of 2000. The results are summarized as follows. A Rohrer index was used to define obesity. The proportions of severe underweight, underweight, normal, overweight, and obese were 0.9%, 16.6%, 57.9%,17.0%, and 7.7% respectively. For the data analysis, the subjects were divided into 3 groups : an underweight group(Rohrer index 109 including severe underweight), a normal group(Rohrer index 110-140), and an obese group(Rohrer index 141 including overweight). With regard to the satisfaction with school lunches, the proportions of children who were satisfied, neutral, and unsatisfied were 27.2%, 59.6% and 13.2% respectively. The proportion of the satisfaction with school lunches was significantly higher in the male group than in the female group(p〈0.05), and the proportion of the dissatisfaction with school lunches was significantly increased with obesity index(p〈0.05). The largest proportion of children who were satisfied with school lunches answered they felt hungry(56.3%) and the food tasted good(42.2%). Children sho were not satisfied with school lunches answered that the food was not tasty(93.5%), they did not have ant appetite(9.7%), and others. The children not finishing school lunches(leftovers) occasionally or always were 47.7% of the subjects. The behavior of leaving lunch foods was not significantly related to the gender or the frequency of eating snacks, wile it was positively related with dissatisfaction with school lunches(p〈0.01), obesity index(p〈0.05), and the decreased frequency of eating meals per day(p〈0.01). The reasons of school lunch leftovers were food dislikes(67.9%), excess of quantity(39.3%), tastelessness(31.3%), poor appetite(13.4%), and other. The children eating meals twice, 3 times, and 4 times per day were 18.7%, 74.9%, and 6.4% of the subjects respectively. The proportions of the obese and the satisfaction with school lunches were not changed significantly according to the frequency of eating meals, while the proportion of children leaving school lunches was significantly higher in the group of eating meals twice per day than in the other groups(p〈0.01). The frequency of eating snacks was not related to the obesity index, the proportion of school lunch leftovers, or the frequency of eating meals, while the proportion of satisfaction with school lunches was significantly higher in the group of eating snacks 1-2 times per day than in the other groups(p〈0.01). In conclusion, it is necessary to have children enjoy school lunches with efforts to improve the food´s taste in the school food services and to reexamine the serving sizes for the children, in addition to the nutrition education for the children to eat a variety of foods.

The purpose of this study was to evaluate the energy intake and energy expenditure of obese children. The body weight and height were measured, and the daily energy intake and activity pattern assessed for one day, using the 24 hour recall method and interviews in 83 elementary school children (59 boys and 24 girls). The average age, height, weight, ideal body weight and obesity index in boys and girls were 11.8 years, 144.8 cm, 54.2 kg, 39.9 kg and 35.9% and 11.5 years, 140.8 cm, 48.9 kg, 36.9 kg and 33.7%, respectively. The mean daily energy intakes of boys and girls were 1,670.5 and 1,656.5 kcal; these being 76.4 and 88.5% of estimated energy requirement for Koreans, respectively. The energy intake ratio from carbohydrates, proteins and fats in boys and girls were 61.5:14.7:23.6 and 62.0:14.7:23.7, respectively. The resting energy expenditure, as estimated by the Harris-Benedict, WHO/NAO/FAO and Korean DRI formulae in boys and girls were 1,452.7, 1,239.2 and 1,629.2 kcal and 1,323.9, 1,156.0 and 1,252.4 kcal, respectively. The activity coefficient for both the boys and girls was 1.39. The daily energy expenditure of boys (1,990.7 kcal) was significantly higher than that of girls (1712.1 kcal). No significant correlations were found between the obesity index, energy intake and energy expenditure. These results suggested that a nutrition and exercise program is required to increase the energy expenditure of elementary school children. Further research will be needed to assess multiple dietary factors and dove]lop a standard method for assessing the energy expenditure of obese children.

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)

This study was conducted to develop a comprehensive program for improving obese children's living habits such as wearing clothing and eating, and their self-esteem. Thirteen obese elementary school children, six boys and seven girls in the 4th to 6th grade, voluntarily participated in a ten-week intervention program. During the program, the obese children filled out a checklist consisted of daily ambient temperature inside the house, weight of clothing, meal diary, time taken for physical exercise, time taken for watching TV, etc. After carrying out the program, its effect was testified and evaluated. Percent body fat of the children measured using a body composition analyzer was reduced by $1.9\%$ after the program (p<.01). Wearing behavior of clothing was positively changed in view of the high correlation between ambient temperature and clothing weight (r=-.917, p<.01). Ability of dietary self control was improved and eating time was lengthened. Self-esteem was improved in global self-worth, athletic competence, and behavior/conduct. It was suggested that active interest of the family would be helpful and that an intervention program over longer than ten week would be necessary to improve childhood obesity.

As the population of overweight and obese children is rising rapidly around the world, there are many researches on purchasing and wearing children's clothing and optimal sizes, but researches on obese children are still inadequate. This study was carried out on 192 obese children over 75% in BMI. The purpose of the study was to set up the optimal interval of sizing system using the loss function which would be a guide for obese children for selecting ready to wear of suitable size. Introducing a loss function, which reflects how much the purchasing desire changes according to the difference, we formulate the problem and suggest a procedure to determine the optimal standard sizes minimizing the loss. These results were as follows ; In size chart of top's, 4 sizes had been determined by a loss function, had covered more than 91.1% of all subjects. In size chart of bottom's, 5 sizes had been determined by a loss function, had covered more than 87.0% of all subjects.

In the present study, in order to improve elementary students’ nutrition knowledge and form correct eating habits, dietitian in charge executed nutrition education for 4th-, 5th- and 6th-grade students at Namchang Elementary School in Suwon, Gyeonggi-do using various educational media for five weeks and two sessions a week (a total of 10 sessions) through discretional activity classes. As for change in nutritional knowledge after nutrition education, 4th-grade students showed improvement by 24.3points(p<0.001), 5th-grade ones by 18.0(p<0.001), and 6th-grade ones by 16.7(p<0.001). With regard to change in dietary habits after education, no effect was observed in the improvement of dietary life but the score of dietary habits was improved as a whole. Nutritional knowledge and dietary habits were in a positive correlation with each other before education(r=0.406, p<0.001), but in no correlation after education. Nutritional knowledge and dietary habit practice plan were in a positive correlation after education(r=0.310, p<0.01). With regard to nutritional knowledge after nutrition education by children’s body type measured using Rohrer Index, knowledge increased significantly in normal children(p<0.001), obese children(p<0.001) and highly obese children(p<0.05) but not in slim children. the effect of education was not significant for children’s dietary habits. Practice plan showed significant changes in all of children(p<0.001). This suggests that nutrition education should be executed from early age. It is necessary to define the goals of systematic nutrition education fit for children’s level and to develop various education programs and teaching materials.
