The obesity incidence rate of children in Korea has increased from 2 to 3% in 1970 to 15% in 2004. The purpose of this study was to evaluate the effect of diet on obesity, and serum cholesterol and triglyceride concentrations by obese index in Korean elementary school students. The subjects were three hundred and thirteen students(male 157, female 156). Height, weight and body fat were measured. Dietary records by the 24-hr recall method were taken for 3 days, and serum cholesterol and triglyceride concentrations were determined. The obesity index was calculated by the Korean of Pediatrics Association standards. Nutrient intakes were calculated by CAN PRO. Almost twenty percent(19.8%) of the subjects were underweight, 60.1 % were normal, 10.2% were overweight and 9.9% were obesity. The obesity incidence rate of the males was not different from the females. Energy and nutrients intakes containing fatty acids were not significantly different by the obesity index. All the subjects had 59.7%～61.1% of carbohydrate and 24.2%～25.6% of fat for energy. Serum cholesterol concentrations of the obesity group(177.3 mg/dl) was higher than those of the underweight group(161.8 mg/dl) and normal weight group(163.5 mg/dl) and overweight group(163.8 mg/dl). Twenty nine percent of the obesity group had serum cholesterol concentrations over 200mg/dl, as compared with 4.8% of the normal and underweight group. Serum triglyceride in the obesity group(103.0mg/dl) was higher than those of the underweight group(79.7 mg/dL), normal weight group(81.0 mg/dl) and overweight group(81.1 mg/dl). Serum total cholesterol concentrations were correlated with the obese index, PIBW, R hrer index at p<0.001, with BMI at p<0.01 and with waist/hip ratio at p<0.05. Serum triglyceride concentrations were correlated with the obese index, PIBW, R hrer index at p<0.01. It is concluded that obesity increases serum total cholesterol concentrations and triglyceride concentrations, and that the obesity preventive program for normal weight children, and weight reduction program for obese children are necessary for elementary school children's education.

Purpose: Little is known about the dieting experiences of obese adolescent boys, as the majority of studies on obesity in children and adolescents have included only girls. This qualitative study was designed to explore the ways in which male middle school boys attach subjective meanings to their obese bodies, and experience dieting practices in their everyday lives. Methods: Fifteen obese boys aged 14 to 16 were interviewed via in-depth, face-to-face interviews. All interview data were audiotaped, transcribed, and analyzed using thematic analysis. Results: Having a large build and increased strength that prevented bullying by peers had positive meanings participants attributed to their obese bodies. However, negative meanings existed as well, including feeling heavy and having no physical endurance, having a clammy and odorous body, and being bullied and vulnerable to disease. With respect to dieting experiences, multiple positive and negative subthemes were identified. Conclusion: The findings of this study show the intersection between adolescence and everyday life challenges for obese middle school boys in the Korean culture. Further, recommendations for healthcare professionals include a gender-specific approaches when intervening and planning programs for obese adolescents.

In this study, the relationships among obesity, food behavior, and personality traits were studied in male and female elementary school children. The obesity rates were calculated via the measured heights and weights of the subjects. Food behavior was surveyed via a questionnaire. Personality traits were evaluated using an authorized personality test. The obesity rates in the child subjects in this study were 34.1%in the male children, and 28.7% in the female children, and the rates of underweight were 18.2% in the males and 28.7% in the females. The percentage of obese children was slightly higher in the male population than in the female population. With regard to food behavior, the females evidenced significantly higher points than the males, particularly on the items designated 'slow eating' and 'stop eating upon satiety'. Among the personality traits assessed herein, which included emotional stability, general activity, sociability, masculinity, responsibility, reflectiveness, and superiority, the females evidenced significantly higher sociability scores than the males. The personality traits did not appear to be significantly associated with the obesity rate. However, the obese children scored lowest on all personality traits among the three groups. In terms of the relationship between food behavior and personality traits, children with high stability, sociability, responsibility, and superiority also had significantly higher food behavior scores. These results imply that the maintenance of good food behavior may enhance stability, sociability, responsibility, and superiority in children.

This study was designed to evaluate food habits, anthropometry and obesity of 252 children(136 boys, 116 girls) aged $2{\sim}6$ years old. The anthropometric indices were measured and food habits were surveyed. Average food habit score was 11.7/20.0 in boys and 11.8/20.0 in girls. It was found that 60.3% of the subjects belonged to fair score group(7-13) in food habits, while subjects in poor (0-6) and in excellent (14-20) were 30.6% and 9.1% respectively. There was no significant difference in food habits score between boys and girls. The food habits score tended to be higher as the mother's education level, total family income, number of siblings were increased. The mean height, weight and chest circumference of the subjects were much higher than the Korean standards. Evaluating the obesity by weight for height, 77.8% subjects was normal, 4.0% was underweight and 18.3% was obese. Underweight children did not seem to enjoy their meals and ate too slowly compared to normal or obese children. Therefore they needed to promote food habits by good nutritional education.

This study was an investigation of obesity, food habits and daily nutrient intakes of the 4th grade elementary school students in daejeon. A total of 148 children(male:71, female:77) participated in the study. We classified the subjects into normal group and obese group according to the grade of obesity indices by body fat ratio(BFR), 70% of the male and 31% of the female were obese group. The average height, weight were $140.1{\pm}4.9cm$, $33.0{\pm}3.6kg$(obese group), $141.9{\pm}5.7cm$, $42.0{\pm}3.6kg$(normal group) for the male, $141.2{\pm}6.4cm$, $42.4{\pm}6.2kg$(obese group), $139.5{\pm}6.4cm$, $33.0{\pm}4.5kg$(normal group) for the female. Weight showed a noticeable increase in the obese group, but height was not statistically significant. In dietary habits, it wasn't statistically significant but male obese group showed statistically increase in terms of eating fast(p>0.05) and eating snacks before sleeping(p>0.01) and female obese group was higher in frequency of eating out a month than normal group. Energy intakes of obese group was more than normal group and the average intakes of Vit. A, folic acid, Ca, were below the RI. The average intakes of vit A, vit C, folic acid, Ca, were also below the RI in normal group. The average intakes of vit A, folic acid, Ca, Fe were below the RI in female. Especially in female the intake of Ca was only 53.6%(obese group), 56.4%(normal group) of RI. From these results, we knew prevalence of obesity in elementary school students were high and obese groups were high in energy intakes but low in essential nutrients. Therefore we have to try to prevent and treat childhood obesity. So nutrition education of balanced diet and good dietary habits is needed for elementary school students.

Purpose: We investigated the association of effector memory (EM) CD8⁺ T cell and CD4⁺ T cell immunity with metabolic syndrome (MS). Methods: Surface and intracellular staining of peripheral blood mononuclear cells was performed. Anti-interleukin-7 receptor-alpha (IL-7Rα) and CX3CR1 antibodies were used to stain the subsets of EM CD8⁺ T cells, while anti-interferon-gamma (IFN-γ), interleukin-17 (IL-17), and forkhead box P3 (FOXP3) antibodies were used for CD4⁺ T cell subsets. Results: Of the 47 obese children, 11 were female. Children with MS had significantly higher levels of serum insulin (34.8±13.8 vs. 16.4±6.3 µU/mL, p<0.001) and homeostasis model assessment of insulin resistance (8.9±4.1 vs. 3.9±1.5, p<0.001) than children without MS. Children with MS revealed significantly higher frequencies of IL-7Rα^low CD8⁺ T cells (60.1±19.1% vs. 48.4±11.5%, p=0.047) and IL-7Rα^lowCX3CR1⁺ CD8⁺ T cells (53.8±20.1% vs. 41.5±11.9%, p=0.036) than children without MS. As the serum triglyceride levels increased, the frequency of IL-7Rα^lowCX3CR1⁺ and IL-7Rα^highCX3CR1^- CD8⁺ T cells increased and decreased, respectively (r=0.335, p=0.014 and r=-0.350, p=0.010, respectively), in 47 children. However, no CD4⁺ T cell subset parameters were significantly different between children with and without MS. Conclusion: In obese children with MS, the changes in immunity due to changes in EM CD8⁺ T cells might be related to the morbidity of obesity.

Objectives: This study was to identify the food habits, dietary attitudes and exercise habits of senior elementary students and provide basic data for the development an obesity management program for these children. Methods: The survey participants were 626 fourth to sixth grade elementary students in G city. Data were analyzed by descriptive statistics, $\chi^2$-test, t-test, ANOVA and multiple logistic regression. Results: The prevalence of obesity was 9.1%. The score of food habits and dietary attitudes at normal-weight group was higher than that of obese group. The food habits of obese group were significantly different according to gender and consideration eating between meals too often as bad habits. The dietary attitudes were significantly different according to interest in obesity control and consideration eating fast and fat food preference as bad habits in obese group. The factors such as grade, intension in weight control and consideration eating fast, overeating, fat food preference and predilection for some food as bad habits were related to obesity. Conclusion: Food habits and dietary attitudes have relation with obesity of senior elementary students. Thus, to develop of obesity management program for senior elementary students, we considered the food habits and dietary attitudes of them.
