Objective: To examine the effects of sodium intake on the correlations between the saltsensitive gene ${\alpha}$-adducin 1 (ADD1) and inflammatory cytokines in Korean childhood obesity. Methods: A total of 2,070 students aged 8-9 years old participated in this study. The anthropometrics, serum biochemistry profile, inflammatory cytokines, and three-day dietary assessment were analyzed according to sex, obesity degree, and ADD1 polymorphism. Results: The obesity prevalence was higher in boys (15.6%) than in girls (11.9%). Boys also showed higher values in anthropometrics; lipid, glucose, and insulin profiles; total calorie intakes, as well as those of sodium and calcium compared with those of the girls. The more obese were boys and girls, the higher were the anthropometrics and the blood levels (total cholesterol, triglyceride, low-density lipoprotein cholesterol, fasting blood sugar, and insulin), but the lower was high-density lipoprotein cholesterol. The obese boys had significantly higher sodium and Na/K intakes, while the obese girls had higher visfatin level and Na/K intake. In addition, an increase in the risk factors for blood pressure and obesity in ADD1 variants was identified. Serum tumor necrosis $factor-{\alpha}$($TNF-{\alpha}$) significantly increased with increasing sodium intake in the ADD1 W allele carriers, regardless of sex. The presence of obesity with the ADD1 W allele induced inflammatory accelerators such as $TNF-{\alpha}$ or C-reactive protein(CRP) with higher sodium intake. Conclusion: Obese children with an ADD1w allele can experience a more complex form of obesity than non-obese when exposed to an obesity-inducing environment and need to be controlled sodium intake in the diet.

This study was carried out to investigate the difference of the body image recognition, food habits, food behaviors and nutrient intake according to the obesity index(underweight-, normal-, obese group) in children(aged 10.8 ys, 47 boys, 33 girls). Subjects were eva1uated based an anthrofometric measurement and questionnaries including food record diary in Changwon. The results are summarized as follows. The weight, BMI, body fat, waist circumference, hip circumference and birth weight except height showed a significant difference between the three groups(p<0.001). The waist and hip circumference showed the possibility of being a predictor of obesity in children. The children's obesity was related to mother's weight(p<0.01), but not to father's. Ninety percent of the obese group, 47.8% of the normal group, and 37.8% of the underweight group preferred a thinner figure than their current status. The underweight group did more exercise regularly than the other groups. The underweight and obese groups had more irregular meal times and foster eating habits compared to the normal group. Most of subjects(89.9%) had an overeating habit, and tole ratio of the overeating habit increased with obesity. Fifty five percent of the subjects clad the habit of skipping meals, mainly breakfast. 46.8% of the subjects ate snacks more than twice per a day, the underweight and obese groups had snacks more of than the normal group. The preferred snack was 'cookies'and 'fruits ＆ juices'. 53.8% of the subjects had a prejudice for special food(especially 'pulses'(37.9%) and 'vegetables'(31.0%)). The assessment scores of food behaviors was relatively low in most of the subjects. Most nutrient intakes, except vitamin B$_1$, C and phosphate, were lower than those of Korean RDA. The nutrient intake of the normal group was higher than the underweight and obese groups. The results of this study showed some nutritional problems, which indicates the need for nutritional management for the children. To educate children, who are able to change their food habits and lifestyle, each means to help healthy growth and to help them become healthy adults.

The widespread pursuit of a thin physique may have a detrimental impact on the wellbeing of preadolescents. The influence of body image distortions on the lifestyles, dieting behaviors, and psychological factors was investigated in 631 fifth and sixth grade children in Kyeonggi-do, Korea. Children were classified into three weight groups (underweight, normal, and overweight) and three perception groups (underestimation, normal, and overestimation). Necessary information was obtained by questionnaire, and each subject's weight status was determined by the Rohrer index calculated from the annual measurement records, which were obtained from the school. According to their current weights, 57.4% of children were normal and 32.2% were overweight or obese, 16.6% of the children overestimated their body weight, and 55.2% had an undistorted body image. Overweight children had desirable lifestyles and dietary habits and presented reasonable weight control behaviors. Compared to those without distortion, the overestimated group had greater interest in weight control ($P$ = 0.003) and dissatisfaction with their body weights ($P$ = 0.011), presented unhealthy reasons to lose weight ($P$ = 0.026), and had higher scores for "feeling sad when comparing own body with others" ($P$ = 0.000) and for "easily getting annoyed and tired" ($P$ = 0.037), even though they had similar obesity indices. More subjects from the overestimation group ($P$ = 0.006) chose drama/movies as their favorite TV programs, suggesting a possible role for the media in body image distortion. These findings suggest that body image distortion can lead preadolescents to develop stress about obesity and unhealthy dieting practices, despite similar obesity indices to those without distorted body images. These results emphasize the importance of having an undistorted body image.

The purpose of this study was to estimate the prevalence and to identify risk factors of overweight among preschool children in Korea. The study subjects were 750 children, aged 2-6, attending child care centers in Korea. A measurement of the height and weight of the children, as well as collection of wide range of variables including general characteristics, and potential factors related with dietary habit for children and their parents, were conducted. Overweight was defined based on more than 110% of ideal body weight. A logistic regression analysis was adopted to identify the factors associated with overweight. Subjects were classified into three categories according to the obesity index : underweight(PIBW〈90%, n=34), normal(90%$\leq$PIBW〈110%, n=577), and overweight(PIBW$\geq$110%, n=139). The overall prevalence of overweight and underweight of the subjects were 21.3% and 4.0% of the boys and 15.5% and 5.1% of the girls respectively. Parent's obesity was associated with a higher risk of overweight on girls. Subjects o the third quartile(girls) and fourth quartile(boys) of income level had a substantially higher risk of overweight than did those in the first quartile. Fast eating, overeating, and food prejudice were also associated with an increased risk of overweight. The results of a logistic regression analysis showed that the eating habits and food preferences of the children were the most influencial factors on overweight. These finding may imply the importance of early stage nutrition education on rational dietary habit to prevent prevailing obesity of preschool in Korea.

Purpose： The purpose of this study was to investigate the actual conditions of obesity, and the factors related to children's obesity. Method： The subjects were 568 students (5th, 6th grades) of ten elementary schools in a small city of about 350,000. Subjects self-reported after being instructed by researchers to identify health habits and attitudes toward obesity. The Rohrer index was calculated by using annual physical examinations preformed by the schools. Result： 17.5％ of the subjects were under weight, 22.2％ were overweight, and 60.3％ were normal. In girls, the under weight group was much larger, in boys the overweight group was larger. 46.2％ of overweight children had a familial tendency to obesity. 60.6％ of boys and 60％ of girls were on a diet in order to improve their looks or to prevent ridicule from mends. On average, one-third of the subjects misunderstood their own weight level. Subjects spent 3-4hours on weekdays, and over 6hours on the weekend watching TV or using personal computers. The overweight group enjoyed eating meat, fish, beans and vegetables, while the normal group tended to prefer fruit. Conclusion： Health education programs which guide elementary school students to form better health habits, more accurate perceptions of their own body weight, and better attitudes toward obesity and which make students aware of the importance of exercise, a healthy diet, and reducing time spent in front of TVs and computers may help them to keep at their appropriate weight.

Purpose: The purpose of this study was to identify the effects of a school-based obesity control program based on behavior modification and self-efficacy for obese elementary school children. The program was composed of strategies to modify diet and exercise habits and to increase self-efficacy. Method: The subjects were 57 obese children (experimental group = 28, control group = 29) whose Rohler index was 150 and over. The program was implemented once a week for 12 weeks from September 16 to December 12, 2003. The data was analyzed by Fisher's exact probability, $x^2$-test, t-test, and Wilcoxon Rank Sum test. Result: The Rohler index, fat mass and lean body mass of the experimental group positively changed after the intervention more than those of the control group, but there was a significant difference in the Rohler index only (t=2.06, p=.045). In addition, obesity stress significantly decreased (z=-2.86, p=.047) and dietary self-efficacy significantly increased (t=2.35, p=.023) in the experimental group than those of the control group. Conclusion: This study supports that a school-based obesity control program based on behavior modification and self-efficacy can be effective in decreasing obesity stress and increasing dietary self-efficacy. Parents, school nurses and the other support groups should be encouraged to participate from the planning stage of the program to be effective in weight control of obese elementary school children. Also school-based program should be implemented as an essential course in the curriculum, not as an elective.

Childhood obesity has rapidly increased worldwide and is one of the most serious health problems in this age group. In order to prevent and manage childhood obesity, we developed a nutrition education website. The website consisted of three parts. The first part was made for self-assessment with regard to obesity index, dietary habits, food frequency, dietary attitude, nutrition knowledge, nutrient intake, energy expenditure, and the stage of behavioral change, and tailored messages and advice according to the assessment results. A total of 612 real-size food photos as well as a nutrient database of 3,346 foods and 541 dishes were created to help children estimate nutrient intakes accurately. In addition, an energy expenditure database of 156 activities for children was established to calculate calorie consumption. The second part was made for setting long-term and short-term goals and keeping track of the changes in energy intake and expenditure in one's own page. The third part was made for education. Various types of nutrition information were provided; texts, pictures, calculators and games. The readability and design of the website were evaluated by 46 obese children. Usefulness, design and readability of the website were found to be desirable for children. This website is expected to be used by an obese child alone or with parents or nutrition teachers in order to control body weight through healthy dietary habits and physical activities. In addition, a non-obese child can also use this website for maintaining healthy dietary habits and preventing obesity.

Objective : As today obese children have increased rapidly in Korea, the interest has been much increased. The childhood obesity causes not only physical problems but also psychosocial problems and it is more difficult than that of adult to treat. That's why we started to intervene actively. Methods : In the Oriental Medical Center, several children were treated for obesity with aroma massage, low frequency wave acupuncture therapy. auricular acupuncture therapy and behavior modification and 3 children over the middle level are mentioned in this study with good results. Results : 1) After treatments, they became taller$(1.1667{\pm}0.8505cm)$. 2) After treatments, they lost their weights$(1.6333{\pm}0.7768kg)$. 3) After treatments, their BMI and OI were reduced$(1.4667{\pm}0.5774kg/m^2,\;9.8{\pm}1.7776%)$. Conclusion : We report the good results of oriental medicine on three cases of obese children over the middle level. And the further study is needed with more cases, longer duration and other tools.

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: The risk of cardiovascular disease (CVD) has been shown to be associated with systemic inflammation in obese adults with metabolic syndrome (MetS). The aims of this study were to evaluate the prevalence of MetS and its relation to inflammatory markers in obese Thai children. Methods: A cross-sectional study was conducted. Children with history of endogenous obesity, chronic diseases, drug ingestion, and any acute illness within 2 weeks prior to enrollment were excluded. Their fasting blood glucose (FBG) levels, oral glucose tolerance tests, insulin, lipid profiles, and selected inflammatory markers, including interleukin-6, tumor necrosis factor-alpha, and high-sensitivity C-reactive protein (hs-CRP) levels, were tested. Results: In this study, 58 obese Thai children (female, 20; male, 38) with a mean body mass index z score of $5.1{\pm}2.2$ were enrolled. The prevalence of MetS and prediabetes was 31% and 17.2%, respectively. None of the children had diabetes. FBG levels, 2-hour glucose levels, and lipid profiles were not statistically different between those with and without MetS. However, obese children with MetS had higher insulin levels and homeostasis model assessment of insulin resistance values. Elevated hs-CRP levels were found in 69% of the cases, although it was not statistically different between the 2 groups. Conclusion: We described a substantial prevalence of MetS in Thai obese children. Regardless of MetS status, two-thirds of the obese children had elevated hs-CRP level, indicating subtle ongoing inflammatory process. This chronic inflammation feasibly predisposes them to CVD in the future, even in children without MetS.
