Purpose: This study was done to examine body satisfaction of children, self-rated health of children and parent-child attachment as perceived by children and their mothers in relation to children's health behavior and to identify factors affecting health behavior of children. Ultimately the purpose of this study was to provide basic data to develop health promotion programs for children. Methods: Participants were 140 couples, 4th grade elementary school students and their mothers residing in Busan. Data collection was done during June 1 and July 31, 2010. The data were analyzed using paired t-test, Pearson correlation coefficients and stepwise multiple regression with PASW 18.0 program. Results: Children and mothers rated body satisfaction of the child differently. Children's responses for body satisfaction of child and parent-child attachment were associated with health behavior of children. Self-rated health perceived by children was also a factor affecting health behavior, as were body satisfaction perceived by children and mothers' perception of body satisfaction of child in that order. These variables explained 18.2% of the total variances in health behavior of children. Conclusion: The findings indicate that body satisfaction and self-rated health of children are important variables to target within intervention research and treatment programs for health promotion behavior of children at home and school.

As children's apparel industry expands, there are many researches on purchasing and wearing children's clothing and optimal sizes, but researches on purchasing and wearing children's clothing and the appropriateness of sizes comparing average body shape and obese children are still inadequate. Therefore, in this research Late Elementary Schoolgirls ranging in age from 12 to 13 are categorized into the average or the obese body type, and by comparing and analyzing purchasing and wearing children's clothing and the appropriateness of its sizes between these groups, the problems in the size system of children's apparel are realized and the basic information about designing children's clothing for average body shape and non-average body shape(out-size)children are presented. The survey questions were composed of topics about general personal information, the purchasing practice and wearing practice, the appropriateness of its size when wearing children's clothing and the practice of mending apparel according to the satisfaction level of children's clothing sizes. Because subjects are often too big to wear children's clothing, and in the case of obese children the deviation of a body type is amplified, therefore in buying and wearing children's clothing, they demonstrate different forms of purchasing and wearing characteristics than adults. Considering the practice of increasing obesity in children due to westernized eating habits and decreased physical activities, along with developing programs for improving obesity, the development of an optimal size system in response to various body types will become an important challenge.

This Study was carried out to find out regional differences about dietary life and factors associated with meal of school children and adolescents between urban and rural area. Forty students from each of the nationwide 51 schools of three different levels(elementary, middle and high school) were surveyed by self-developed questionnaires. Total of 1,886 questionnaires (1,243 from urban and 681 from rural) were collected and distribution of subjects was 544 from elementary school, 661 from middle school, and 681 from high school. The results were summarized as follows. BMI and degree of satisfaction on body weight of elementary and middle school subjects were not significantly different between urban and rural area. But there were significant regional differences in $BMI(urban\;21.2{\pm}3.0,\;rural\;20.5{\pm}2.8,\;p<0.05)$ and degree of satisfaction on body weight of high school subjects(p<0.001). Elementary(p<0.01) and middle school(p<0.05) subjects in urban area had exercised more frequently than those in rural area. Regularity of having breakfast was not significantly different between urban and rural area at each of three different levels of school. Most subjects(urban 92.2%, rural 92.1%) had lunch regularly by virtue of school lunch service. Regularity of having dinner of elementary(p<0.01) and high school subjects (p<0.01) was significantly different between urban and rural area. Reason for skipping dinner of high school subjects was significantly different between urban and rural area (p<0.05). The most delicious meal was dinner for 51.8% of the urban high school subjects and lunch for 51.7% of the rural subjects. Only one third had intention of participating in school breakfast program regardless of region and levels of school. The findings suggested that nutrition education programs for school children and adolescents include different strategy according to region and levels of schools.

Objectives The purpose of this study was to validate the biopsychological structure of Sasang Personality Questionnaire (SPQ) measuring Yin-Yang temperament with Junior version of Temperament and Character Inventory (JTCI) for temperament and Body Mass Index (BMI) and Pondera Index (PI) for physical constitution in elementary school students. Methods 903 Korean elementary school students (430 boys and 473 girls) completed SPQ, JTCI, and height and weight measures. Then they were analyzed by their genders and age groups. The correlation between SPQ and JTCI subscales were examined. The differences found in the SPQ and JTCI subscales, BMI and PI among high (30%), middle (40%), and low (30%) SPQ groups were investigated by analysis of variance. The profile analysis was also performed to compare JTCI subscale profiles of three SPQ total score groups. Results The SPQ score was significantly (p<0.001), and positively correlated with the JTCI Novelty-Seeking and negatively with the JTCI Harm-Avoidance. The JTCI Novelty-Seeking score of high SPQ group was significantly (p<0.001) higher than that of low SPQ group, and the JTCI Harm-Avoidance score of low SPQ group was significantly higher than that of high SPQ group. The JTCI subscale profiles for three SPQ groups were significantly (p<0.001) different for boys and girls. Significant correlations between BMI and SPQ were not found. PI and BMI of high and low SPQ groups were not significantly different. Conclusions The SPQ was shown to have robust biopsychological structure in elementary school students. It would be useful clinical measures for Sasang typology in pediatric patients.

This study was conducted to evaluate the nutritional status of elementary school lunch programs. The subjects of this study consisted of 170 elementary school students(male 51.8% : female 48.2%) in the 5th and 6th grades. The dietary intake of nutrients was assessed by the modified 24-hour recall method. The results are summarized as follows: the average body weight was 41.3$\pm$7.93kg for boys and 40.5$\pm$ 8.35kg for girls. The average height was 149.5$\pm$5.88cm for boys and 146.2$\pm$5.82cm for girls. The total daily energy and nutrient intake was below the RDA's except for the intake of niacin and ascorbic acid. School lunchs provided 31.5% of total energy intake ; 32.5% of carbohydrate intake, 31.9% of protein intake and 33.4% of fat intake. Therefore, school lunchs largely contributed to the nutritional balance of these children. The food habit score was poor for 40.6% of the subjects.

Most research on verbal interaction in school has used general frameworks, not including general sense that encompass 'elementary' and 'science'. Considering the current framework, we developed a new framework containing items such as safety and science terms. In this study, we compared 2 beginner teachers and 2 career teachers using new frameworks. After preliminary experiments, we recorded 4 classes per each person and recorded all interaction. It was revealed that the career teachers shows more convergent question and agreement to students. And in experimental class the career teachers give more attention for safety. This study may present that it is necessary for beginner teachers to be trained focusing differences.

Objectives: This study aimed to develop a school-centered healthy eating environment for children in elementary care classrooms and prevent incorrect eating habits and obesity through the development and application of standardized healthy eating habit-forming educational materials. Methods: Ten schools in eight districts of Gyeonggi-do and 400 students from 19 care classes were selected. Based on the developed educational materials, the program was applied to students once in two weeks. 'Notices for Parents' forms were also sent to the students' home to educate their parents. Pre and post-surveys were conducted to evaluate the effectiveness of the education. The pre-education, education, and aftercare were conducted from September 28 to September 31, 2016, from October 3 to November 30, 2016, and from December 5 to December 9, 2016, respectively. Results: The healthy eating program for elementary care classes was designed to develop a school-centered healthy eating environment and provide standardized educational material for healthy eating habits. Twelve educational topics were developed: , , , , , , , , , , , and . Moreover, the materials were produced in four forms: for students, for after school caring teachers, for external specialists, and for parents. The effectiveness evaluation was conducted to confirm the application of the program. The average eating habits score was 3.3 ± 0.6, with no significant difference between before and after application. The score of overall satisfaction of the education was 3.9 ± 0.9. The most satisfying content was 'Did you get to know how to eat evenly?'. Significant increases were observed in two contents for parents regarding their children's knowledge changes after the education: 'Five nutrients needed for growing children' and 'Knowing sugar foods and sugar-containing foods'. On the other hand, their educational satisfaction was 3.6 ± 0.6, which was lower than the children's satisfaction. This might be because their education was conducted only through the 'Notices for Parents' form. Conclusions: In the long term, the healthy eating habit-formation education for lower elementary school children is expected to be beneficial. To prevent obesity and establish healthy eating habits of children, it is important to develop healthy eating education programs centered on elementary school aftercare classes, including the development of educational materials and an application system through connection with the home and community.

The purpose of this study was to investigate the relationship among nutritional status, serum lipids and leptin of 134 elementary school students with different obesity index residing in Kyunggi-do, Korea. Subjects were assigned to under weight, normal weight or over weight group according to the their obesity index. Their nutritional status, serum lipid and leptin levels were evaluated based on 24-hr dietary recalls, anthropometric measurements and blood analysis. The mean weight, height and obesity index of total subjects was 150.8cm, 45.6kg and 5.4%. The mean % of body fat was higher while LBM and TBW (total body water) were lower in over weight subjects than those of other two groups. Total food, plant protein, carbohydrate, and vitamin C intakes of underweight male students were lower than those of overweight male students. The consumption of total fat was the highest in the female normal weight subjects and the lowest in female overweight subjects. Male students consumed more plant protein and vitamin C than female students. The mean daily intake of vitamin B$_2$, calcium and zinc of all subjects did not meet the Korean RDA. Also, iron intake of female students was lower than the Korean RDA. The mean level of serum leptin was the highest in male and female overweight subjects (p＜0.001). The HDL-cholesterol level was the highest in the underweight group of male subjects (p＜0.05) and in the normal weight group of female subjects (p＜0.001) The serum level of leptin and atherogenic index (AI) of females were higher than those of males. Serum leptin of total subjects had significantly positive correlation with obesity index, weight, SBP, body fat, cholesterol intake, serum triglyceride, and AI. However, serum leptin was negatively correlated with LBM, TBW, intake of plant protein, vitamin B$_1$, vitamin C and serum HDL-cholesterol. Obesity index was also positively correlated with weight, SBP, body fat, serum triglyceride and AI. To summarize the results, the vitamin B$_2$, calcium, zinc, iron and fiber intakes should be supplied to elementary school students, especially those who were overweight. The average serum leptin level of students showed remarkably positive correlation with obesity index, body fat, serum lipids and AI. Also, it was suggested that the serum leptin might be related to the dietary factors like cholesterol, plant protein, vitamin B$_1$ and vitamin C of elementary school students.
